The technical field to which the invention relates.

The present invention relates to a clamp for closing a wound or incision. Initially, the present invention has been disclosed in accordance with the Program disclosure documents USPTO U.S. Patent Office Disclosure Document Program in the form of documents, Disclosure Documents No. 448944 and 446186.

The level of technology

The prior art compositions and methods for closing wounds or incisions. Conventional technology of this kind are stitches or brackets, i.e. relate to invasive technologies, which can cause pain and often require the use of anesthetic. Such methods often lead to ugly scars remain in the perforation of the skin and uneven forces acting on the wound or surgical incision between points suturing and intermediate areas of the skin. In addition, after the application of these methods required a visit to hospital or doctor for removal of sutures or brackets.

Although the prior art and other compositions and methods for closing wounds or incisions, they have not received wide acceptance due to inherent limitations of the underlying schemes. There is an obvious need for non-invasive or less traumatic method of closing wounds or incisions, which would be practical and easy to use.

Disclosure of inventions

In a preferred embodiment, the bandage includes a first flat flexible component with the adhesive on the bottom surface and multiple first elongated connecting elements extending in the first direction from one edge of the flexible component. In addition, the bandage includes a second flat flexible component with the adhesive on the bottom surface and one or more second elongated connecting elements extending from one edge of the flexible component in the second direction essentially opposite to the first. To the first elongated connecting elements attached to the first tension element is made with the possibility of transverse displacement of the first flat flexible component towards the edge of the wound. The second tension element attached to the second elongated connecting elements, and he also performed with the possibility of transverse displacement of the second flat flexible component towards the edge of the wound. Tensioning elements contribute to the distribution of the tensile force exerted by the person imposing the bandage of the present invention, across each of the elongated connecting elements to which they are attached. Also provides a means of attaching the first and second elongated connecting elements, matched with the public, the second and the first flat flexible component.

The adhesive applied on the bottom surface of the first and second flat flexible components, chosen based on their compatibility with the skin, as well as the ability to securely hold the dressing in a period of time sufficient for wound healing. In the prior art there are many such materials. Until the bandage they are protected from contamination and oxidation of one or more sheets of protective film. This film removed before applying the bandage, revealing the adhesive.

In embodiments implementing the present invention, in which the first and second flat flexible components thin and extremely flexible, the choice of film covering the adhesive can be carried out based give these components a certain degree of rigidity for ease of dressing. To protect the adhesive on a single flat flexible component can be provided by a multilayer protective film that provides a convenient position for engagement by the fingers of the upper and protected the lower parts of the bandage in the process of blending.

Means attaching the first and second elongated connecting elements respectively to the second and the first flat flexible component in the preferred options for implementation are also adhesives. After the application of the decree is the R components and achieve tension, required for the effective closure of the wound or incision, the elongated connecting element is brought into contact with the flat flexible components, and adhesive fix their position relative to each other. It is clear that in the manufacture of adhesive can be applied to the upper surface of the flat flexible components on the bottom surface of the elongated connecting elements or both. For this application fits a lot of pressure-sensitive adhesives, and the selection of any particular material for the most part depends on the chosen design and optimality criteria. As mentioned above in relation to the adhesive on the bottom surfaces of the flat flexible components, these adhesives before applying dressings protected by a thin removable film.

The dimensions of all components vary within defined functional considerations. For example, to ensure closure of the length of the first and second flat flexible components (i.e. the size of the hand, essentially parallel to the wound or incision) should approximately correspond to the length of the wound or incision. The length of the first and second flat flexible components, due to the length of the wound or incision, mainly determines the width of these components, measured in the direction perpendicular to the length of the first and second flat flexible comp the components in the plane of the bandage. In other words, the ratio of length to width should be selected in such a way as to ensure the application of the adhesive enough to hold the bandage in place after applying to the skin. If the width of the bandage about its length is too small, the bandage after applying will be assigned unreliable and possibly premature and unintentional separation from the skin.

The definition of the correlation length-width actually is empirically and depends on the type of adhesive. Generally speaking, an acceptable ratio of length to width may lie in the range from 1:2 to 8:1. These values are provided as examples and should not be construed as maximum or minimum values of the ratios.

Another parameter related to the choice of dimensions of the elements of the bandage of the present invention, is the distance between the elongated connecting elements. It is important that the distance between adjacent elements of this kind was sufficient for adjusting the position of the first and second flat flexible components in relation to each other. The fact that in the process of wrapping one of these components put on the skin before the other. After applying the second component, the first cannot easily be removed and placed on another place. Therefore, to facilitate accurate installation is loose flat flexible component relative to the same fixed component important factor is sufficient distance between the elongated connecting elements. The absolute minimum value of this distance it is impossible to specify. Probably, for this value the most rational approach is to establish a preferred intervals, expressed in percentage of the length of the bandage. For example, an example of an acceptable interval is the distance value between adjacent elongated connecting elements lying in the range from about 5% to 10% of the length of the bandage, corresponding to the above definition.

In preferred variants of the invention, the flat flexible components, elongated connecting elements and the tension elements described in the preceding paragraph, made of essentially non-elastic polymer material. In the alternative, they can be made of elastic material, which is reinforced inelastic structural component, essentially, inelasticity of the device. The list of such inelastic materials may include, for example, a grid or line of polymeric monofilament. The strengthening of the flat flexible components along the so-called wound edges bandages, as well as the strengthening of the tension elements should preferably be hard and at the same time, inelastic material. For this purpose, preferred, in particular, rigid polymeric material. For example, the R, the device may further comprise a hard plastic strip attached to the edges of the first and second flat flexible components located near the wound or incision and essentially parallel to the wound or incision.

In other preferred embodiments, the implementation of flat flexible components, elongated connecting element and the tension element is made of sheet material, for example of plastic sheet material. Cutting out these items from plastic sheet material with the formation of solid components, then joined to produce functional bandages, is an extremely effective price approach. To provide ventilation to the skin under the bandage sheet material can be perforated. The thickness of the sheet material can be changed depending on the type of use. In addition, as noted above, some portions can be optionally reinforced rigid material.

In the following preferred embodiments, the first and second tensioning elements are designed to remove after the bandage on the skin. The size of the bandage after its imposition on the patient becomes minimum. Reduction of overall dressing size reduces the likelihood of snagging some parts of it, nab is emer, clothing or pillow. When such engagement can tear the bandage from the skin, causing the opening of the wound or incision. In addition, to minimize the overall size of the bandage after applying it provides a more comfortable fit.

The preferred design, which includes the removal of the tension elements, includes linearly spaced perforations or notches, applied across the first and second elongated connecting elements. The first and second tensioning elements are removed by means of a rupture of elongated connecting elements along these perforations.

In another preferred embodiment of the bandage according to the present invention the first and second elongated connecting elements are interleaved. This alternation can be implemented in various ways, obvious to a person skilled in this field. For example, at least one member of a pair of flat flexible components can be cut down together with the elongated connecting elements in the form of a single block, while the corresponding tensioning element is cut out separately. Further, the first and second elongated connecting elements can be positioned with alternating, and then to the corresponding connecting elements, for example, with an adhesive attached individually cut ateneu element.

Another way layout variant implementation, using the specified interleaving, is evident from the following example. Provide the first solid component containing a tension element, a pair of first elongated connecting elements and the first flat flexible component. Provide a second solid component containing a tension element, three second elongated connecting element and the second flat flexible component. The distance between the elongated connecting elements chosen, taking into account the possibility of their rotation when pairing, but given the fact that the average of the second elongated connecting elements being fixed at both ends, prevents the pairing of the two other elements. To ensure the interface of two solid components, it is necessary to cut the specified average item to put in pairing two solid component so that the elongated connecting elements are alternated, and then reconnect the specified secondary element. It is clear that this method of composition is also applicable to variants of implementation, with more than five elongated connecting elements.

Alternative options described with alternating connecting elements was named design with a wide hole in the form of a keyhole. In theconstruction used two one-piece component, made, for example, by way of cutting down. Each of these components contains the first flat flexible component, the elongated connecting element (or several elements) and the tension element. The elongated connecting element of the first solid component placed in the center of the assembled and attached armband, and in the case of multiple items, they are located next to each other. Elongated connecting elements of the second solid component are located on both sides of the same elements of the first solid component with an offset to the outside edges of the dressing. This construction facilitates the manufacture of bandages, because you can both integral component to cut down the normal way, and then insert the first solid component in a relatively wide gap between the two sets of elongated connecting elements of the second solid component. When turning the solid components of the arrangement in one plane corresponding to the superimposed state of the bandage, is their mutual coupling with each other, realized in the preferred embodiment of the present invention.

In another embodiment, the present invention relates to intended for wound closure device of the type indicated above, which, however, has only outlining the second coupling element, extending from the first flat flexible component, and only a single elongated connecting element extending from the second flat flexible component. This option is preferred for use in the case of relatively small wounds or cuts. In this embodiment, designed for small wounds, the width of the flat flexible component is less than approximately 2 cm is Achieved for such wounds or incisions advantage is based on the fact that the elongated connecting element is made extending from edges of the corresponding flexible component offset to the outer edge of this flexible component (i.e. he departs not from the center of the wound edges, and from a point that is offset to one side). If flat flexible component had a sufficiently large width, comprising, for example, 5 cm, attempts efficient way to have the wound edge would lead to deformation due to the flexible nature of the components. When reduced scale proposed under this option, the exercise, the risk of deformation of this type is essentially excluded.

When designing this option so that only the elongated connecting element is moved away from the associated flat flexible component offset to the outer edge, in a two-component device p which is the ability to put each component so that that wound edges essentially parallel to one another and aligned to the center, and elongated connecting elements of each component essentially parallel. When using coated on the reverse side of the adhesive area of the elongated connecting element extending from the first flat flexible component that is attached to the second flat flexible component. Likewise coated on the reverse side of the adhesive area of the elongated connecting element extending from the second flat flexible component that is attached to the first flat flexible component. During the process of designing and manufacturing should pay attention to the fact that the adhesive did not get on elongated coupling element in such a place, the presence of adhesive which will result in contact between the adhesive and the wound.

The device has a tensioning element extending from each of the elongated connecting element on the side, which is opposite to the corresponding flat flexible component. In preferred variants of the invention, the tensioning element can be removed immediately after the fixing device. To facilitate such removal of the material from which the designed device that provides perforation located along a line essentially perpen icularly the main axis of each elongated connecting element. Some properties of the type described here in combination with other variants of the invention are equally applicable to the alternative implementation that uses a single elongated connecting element.

When applying on the skin and the corresponding tension one edge of the first flat flexible component and one edge of the second flat flexible component come as close as possible to the wound or incision and essentially parallel to them. With respect to these edges will be next used the term "wound edge. To facilitate wound healing in preferred embodiments, the implementation of the present invention, these edges are made with the possibility of screwing out out or raise the edges of the skin. It is known that the screwing out out, lifting the edges of the skin or the education of these bumps in the wound or incision prevents eversion of the wound. One way to solve this problem is the presence of a bend at the wound edges. He may have an angular or arcuate shape. The adhesive on the lower section of flat flexible component also covers the portion of the wound edges. After attaching to the skin, this turned edge strives to raise the edges of the skin in contact with it, thereby facilitating healing of a wound or incision.

As indicated above, the preferred embodiments of the present the th of the invention include modifications using the process of cutting. In this embodiment, the elongated connecting elements, respectively, its size can be in the form of belts. In preferred embodiments, implementation of elongated connecting elements cut out section to increase the open area of the surface over the wound. This facilitates the outflow of exudate and application of medicines. Such slots are best realized in the process of cutting.

In addition, in preferred embodiments, the implementation of the bandage of the present invention is arranged to align wound closure. As noted above, a significant factor for the solution of this problem is the gap between adjacent elongated connecting elements. In addition, in preferred embodiments, the bandage according to the invention is provided by the indicators align wound closure. These indicators are visual indicators positioned on a flat flexible components near the wound edge. As a rule, they are made in the form of lines or arrows, essentially directed perpendicular to the wound or incision. When closing a wound or incision Clinician usually performs this procedure manually fingers approximately at the midpoint, and then surgical tassel makes a small mark or draws a line, p is erpendicular wound. These stamps are used for precise location of the device, combining them with alignment indicators on the bandage of the present invention. In addition, to align the wound closure of the first and second flat flexible components can be provided with alignment marks to align them with one another and/or with markers placed directly on the skin.

If necessary, the bandage according to the invention can be made with the possibility of transdermal (skin) drug delivery. It is known that drugs can be delivered transdermal way through the skin. For such applications, at least one flat flexible component attach the pad containing the drug, and so that it could be delivered through the skin. Since the area of the specified lining should not be adhesive contact between the skin and the flat flexible component, for the variant of implementation of such appointment at fixing the bandage may be necessary to increase the size of the flat flexible component. Transdermal delivery of drugs is well known, and for the manufacture and use of the device of the present invention technician is not required overview of the field of technology.

If necessary bandages which the present invention may contain elastic element indicating tension. The purpose of this element is a visual indication achieve the desired tension in the bandage. For example, known materials that change color during the application of a predetermined load. Similarly for this purpose can be used appropriate graphic techniques. In particular, the elastic element indicating the tension may be applied to a graphic image of the rectangle. When the tension of the specified element in this image is drawn. Such an element can be constructed so that the tension of the source image rectangle to a state close to the geometric square, meant the achievement of the desired tension.

Preferably, this elastic element indicating the tension was made with the possibility of removal together with the tensioning elements after dressing. At least the specified item should be placed in a sling so that when superimposed bandage he had no opportunities for further expansion and thereby dropping the previously achieved the desired tension.

The present invention relates also to a method of closing wounds. The method includes the imposition of the above-described dressing a certain way.

In addition, the device according to the invention can be adapted for stretching the skin before chirurgiche is some procedure. We mean, for example, the situation when the surgeon wants to remove a defective piece of skin. If this piece has a more or less circular shape with a diameter of 25 mm, it is easy to imagine the problem that occurs when closing the incision, remaining after such removal. At the present time decide by stretching the skin with the use of invasive procedures, which is placed under the skin with the device type of the balloon and inflate it. After some time, the skin over the device is pulled, and deleting unwanted piece creates a gap that can be closed more easily.

To perform the specified function of the stretching of the skin, you can apply the device according to the present invention. This is done by placing the wound edges of each component of the two component devices on different sides of the removed piece of skin. The device then stretch the manner described above. Because of this overlap, the distance between the two wound edges is relatively high, applied to the device the force increase. To ensure that this is stretching the leather version, the adhesion of the components of the device, it is desirable to provide an adhesive of the tension elements. In this embodiment, there are components that are attached not only due to the adhesion of the contact is between the elongated connecting element (elongated connecting elements) and flat flexible components, but also due to the same contact between the tensioning element and the skin. In this embodiment, after applying device tensioning elements are not removed.

The implementation of the invention

Figure 1 shows the bandage (1) of the present invention in the unstrained condition. It contains the first flat flexible component (5) and the second flat flexible component (25). Each of these components has an upper surface to which is directed the index lines 5 and 25, and invisible in the drawing the lower surface. The lower surface is covered with adhesive, providing attachment to the skin. From the wound edge (20) of the first flat flexible component (5) in the first direction away a few first elongated connecting elements (15), and from the wound edge (42) of the second flat flexible component in a second direction that is generally opposite to the first, there are some second elongated connecting elements (35). To the first elongated connecting elements (15) attached to the first tension element (40), which is made with possibility of transverse displacement of the first flat flexible component (5) in the direction of the wound or incision. Similarly, the second tension element (45) is attached to the second elongated connecting elements (35), and he also performed with the possibility of transverse displacement of the second flat flexible component (25) in the direction of the wound or incision. In preferred embodiments, the implementation of the means of fastening the first and second outlining the x connecting elements (15 and 35), accordingly, the second and the first flat flexible component (25) and 5) contain the adhesive. It can be applied on the bottom surface of the first and second elongated connecting elements (15 and 35) or on the upper surface of the first and second flat flexible components (5 and 25).

Perforation (17 and 37), made in elongated connecting elements (15 and 35), facilitate the separation of the tension elements (40 and 45) from the above items after dressing.

The bottom surface of the first and second flat flexible components at least partially covered by an adhesive that facilitates attachment to the patient's skin. In addition, these adhesives allow you to easily remove the bandage after healing of the wound or incision. Removed manually protective film (not shown) is performed prior to use of the bandage, the function of protection of the adhesive applied on the first and second flat flexible components (5 and 25).

Figure 2 is shown in figure 1 bandage in the tense, but uncommitted state. More specifically, figure 2 shows the first and second flat flexible components (5 and 25)attached by an adhesive to the skin. The tensile force applied to the tension elements (40 and 45), shifts the wound edges (20 and 42) in direction to each other, thereby closing the wound. The bandage is not completed, because the ku elongated connecting elements (15 and 35) is still not fixed with an adhesive on a flat flexible components (5 and 25).

Figure 3 shows shown in figure 1, the bandage taut and fixed (i.e. applied) state. The tension elements (40 and 45), shown in figures 1 and 2, separated by perforations (17 and 37). Elongated connecting elements (15 and 35) are attached to the flat flexible components (5 and 25) with an adhesive. Directly over the wound or incision are slits (47 and 49) in the elongated connecting elements (15 and 35), providing the outflow of exudate and application of medicines.

4 shows an alternative implementation is shown in figure 1 bandage, in which the first flat flexible component (5) is attached to only a single elongated connecting element (15). This option is referred to as a bandage with a wide hole in the form of a keyhole.

Figure 5 shows a transparent breathable protective coating (51) running along the perimeter of the adhesive strip (53). It can be used for protection area overlay bandage of the present invention. Figure 6 shows the protective coating (51)placed on the skin over dressing (1) according to the present invention.

7 is a schematic representation of a two-component device of the present invention, intended for closing wounds. The first and second components of the specified device denoted by respectively the AK 54 and 56. Each of these two components has a single elongated connecting element (15 and 35)connected with the corresponding flat flexible component (5 and 25). Each of these elements (15 and 35) departs from the corresponding flat flexible component (5 and 25) and shifted to the outer edge of this component. This figure using the feather presents no claim to any restrictions example illustration of the application of adhesive to bond the two components. In preferred embodiments of the invention the adhesive is applied on each flat flexible component (5 and 25), and the plot elongated connecting elements (15 and 35). For ease of application and adjustment of a two-component device, closing the wound, is provided by the presence of the tension elements (40 and 45). In preferred embodiments, the implementation for the Department of the tension elements are intended perforation (17 and 37). 7 they are located near the Central zone of the elongated connecting elements. It should be borne in mind that the location of the perforations (17 and 37) is selected from structural considerations. 7 shows also the slot (47 and 49). They are designed to outflow of fluid, as well as to facilitate the application of medicines to the area of the wound.

As can be seen from Fig, in working condition specified offset connecting ale is now allows you to have a two-part device, what both of its components (54 and 56) are mutually aligned. When this wound edges (20 and 42) of each of them (i.e. the closest to the wound or the cut edge of the flat flexible component) are essentially parallel and centered, and essentially become parallel and longitudinal connecting elements (15 and 35), Although Fig shows an extreme version of the offsets of each of the elongated connecting element (when one edge of each of the elongated connecting element is a continuation of one edge of each flat flexible component), such a significant shift is not necessary. The offset is sufficient if each component of the device can be positioned, as noted above, without contact between the first and second elongated connecting elements. In situ coated on the reverse side of the adhesive area of the elongated connecting element (15)extending from the first flat flexible component (5), is attached to the second flat flexible component (25). Similarly, coated on the back side of the adhesive area of the elongated connecting element (35)extending from the second flat flexible component (25)is attached to the first flat flexible component (5).

In the case of medical devices from which retenu for stretching the skin before surgical procedure (for example, when the surgeon wants to remove a defective piece of skin) of the first and second tensioning elements (40, 45 see, for example, Fig.1-3) preferably have on their bottom surfaces are not shown in the drawing the adhesive. In this embodiment, device attachment components (5, 25) is secured as by adhesive contact between the first and second elongated connecting elements (15, 35) and flat flexible components (5, 25), and using the adhesive contact between the tensioning elements (40, 45) and the skin. The presence of an additional adhesive contact created tension elements (40, 45), allows to provide with this option, the medical device is pulling the skin in relatively large distance between the two wound edges, i.e. with increasing force applied to the device.

The method of stretching the skin before surgical procedure according to the invention, carried out using the described two-component medical devices, in which the first and second tensioning elements (40, 45) preferably have an adhesive on its lower surface, includes the following operations:

attach the bottom surface of the first flexible component (5) to the skin of the patient along the first side of the wound,

attach the bottom surface of the second flexible component (25) to casepatient along the second side of the wound,

pull both the first and second tensioning elements (40, 45) to reach elongated connecting elements (15, 35) tension sufficient to close a wound or incision, attach the first elongated connecting elements (15) to the second flexible component, and the first tension element (40) to the skin of the patient and

attach the second elongated connecting element (35) to the first flexible component (5), and the second tension element (45) to the patient's skin. The first tension element (40) and the second tension element (45) can be attached to the skin of the patient, respectively, next to the second flat flexible component (25) and next to the first flat flexible component (5).

According to the described embodiment of the method of tensioning elements (40, 45) is not removed.

An alternative method of stretching the skin additionally includes the steps of separating the first and second tensioning elements (40, 45) respectively from the first and second elongated connecting elements (15, 35).

The method according to the invention avoids the use of invasive procedures with a location under the skin of the inflatable balloon used to date for stretching the skin before surgery.
