The technical field to which the invention relates.

The present invention relates to a clamp for closing a wound or incision.

The level of technology

The prior art compositions and methods for closing wounds or incisions. The conventional methods of closing wounds or incisions are stitches or brackets, that is, relate to invasive technologies, which can be painful and often require the use of anesthetic. Such methods often lead to ugly scars remain in the perforation of the skin and the changing forces acting on the wound or surgical incision between points suturing and intermediate areas of the skin. In addition, such methods do the necessary follow-up visit to the 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 because of the scarcity of the underlying schemes. There is a clear need for non-invasive or less traumatic method of closing a wound or incision, which would be practical and easy to use.

The invention

In a preferred embodiment, the bandage includes a first flat flexible component with the adhesive layer on the bottom surface and multiple first elongated who passed the connecting elements, the waste in the first direction from one of the edges of this component. The dressing also contains a second flat flexible component with the adhesive layer on the bottom surface and one or more second elongated connecting elements extending in a second direction essentially opposite the first direction, from one of the edges of this component.

With the first elongated connecting elements connected 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 is connected with the second elongated connecting elements and is made with 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 superimposing the dressing face, all elongated connecting elements with which they are connected. Also provides a means of securing the first elongated connecting elements on the second flat flexible component and means for securing the second elongated connecting elements on the first flat flexible component.

Adhesive material covering the bottom surface of the first and second flat flexible components can be chosen according to its compatible with the terms of skin, as well as the ability to securely hold the bandage long enough to heal wounds. In the prior art there are many such materials. Until the bandage adhesive layers are protected from contamination and oxidation of one or more strips of the protective film. This film removed before applying the bandage, revealing the adhesive layer.

In embodiments of the present invention, where the first and second flat flexible components thin and extremely flexible, the choice of the protecting adhesive film layer may be made of the calculation give these components a certain degree of rigidity for ease of dressing. To protect the adhesive layer on the same flat flexible component can be provided by several protective film that provides a convenient position for engagement by the fingers of the top and secure the bottom of the bandage in the process of blending.

Means securing the first elongated connecting elements on the second flat flexible component and a second elongated connecting elements on the first flat flexible element in the preferred embodiments are also adhesive layers. After imposition of a flat flexible components and achieve the tension required to close a wound or incision, the elongated connecting element is brought into contact with the flat the mi flexible components, and the adhesive layer thus secures their position relative to each other. It is clear that the production of the adhesive layer can be applied on the upper surface of the flat flexible components on the bottom surface of the elongated connecting elements, or both. For this kind of blend is suitable plenty of self-adhesive materials, and the selection of any particular material largely depends on the design and optimality criteria. As described above with respect to the adhesive layer on the bottom surface of the flat flexible components mentioned adhesive layers are protected with a thin film to be removed before applying a bandage.

The dimensions of all components vary within defined functional considerations. For example, the length of the first and second flat flexible components, i.e. the length of a side essentially parallel to the wound or incision, should approximately correspond to the length of the wound or incision, to ensure closure. 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 direction in which the measured length of the first and second flat flexible components in the plane of the bandage. In other words, attributed the e of length to width should be chosen so that to ensure the application of adhesive material in a quantity sufficient 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 the overlay is not attached securely and prone to premature and unintentional separation from the skin. The definition of the correlation length-width actually is empirically and depends on the type of adhesive material. In General, an acceptable length to width ratio may lie in the range from 1:2 to 8:1. These values of the ratio are given as examples and do not set a maximum or minimum value of.

Another consideration that affects the choice of the sizes 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 elongated connecting elements was enough to install the first and second flat flexible components in relation to each other. More specifically, in the process of wrapping the skin is first wrapped one flat flexible component, and then the other component. After applying the second component, it cannot easily be removed and placed on another place. Therefore, a sufficient distance between the elongated soy is intalniri elements it is important to ensure accurate installation loose flat flexible component relative to the fixed component. It is impossible to specify the absolute minimum value of the distance between the elongated connecting elements. Probably the most rational is the establishment of preferred intervals of values in percentage of the length of the bandage. For example, a distance value between adjacent elongated connecting elements lying in the range from about 5% to 10% of the length of the bandage as defined above, will be an example of an acceptable interval.

In preferred versions of the flat flexible components, extra long connecting components and tensioning elements described in the preceding paragraph, made of essentially non-elastic polymer material. Alternatively, they can be made of flexible material, reinforced inelastic structural element, providing, in essence, the lack of elasticity of the structure. For example, such non-resilient materials may include a grid or line of polymeric monofilament. The strengthening of the flat flexible components along the wound edges of the bandage, as well as increased tension elements should preferably be hard and at the same time, inelastic material. For this purpose, preferred, for example, a rigid polymeric material.

In other preferred embodiments, the step is Okie flexible components, elongated connecting element and the tension element is made of sheet material, such as plastic sheet material. Cutting out these items of plastic sheet material with the formation of the solid components, which are then combined in the manufacture of functional bandages, is an extremely effective price approach. This sheet material can be perforated to provide ventilation to the skin under the bandage. The thickness of the sheet material can be different depending on the type of use. In addition, as described above, some sections of the sheet material can be optionally reinforced with a rigid material.

In the following preferred embodiments of 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 engagement with any portion of the bandage, for example, clothing or pillows. If this happens, can tear the bandage from the skin and the opening of the wound or incision. The process of minimizing the overall size of the bandage after applying it also provides a more comfortable fit.

The preferred design, which include the treno remove the tension elements, includes rectilinear perforations or notches marked on the first and second elongated connecting elements. The first and second tensioning elements are removed by breaking elongated connecting elements along this perforation.

In a further preferred embodiment of the bandage according to the present invention the first and second elongated connecting elements are interleaved. The alternation of these elements can be implemented in various ways, obvious to the expert. For example, at least one flat flexible component can be cut together with the elongated connecting elements in the form of a single whole, while the corresponding tensioning element is cut out separately. First and second elongated connecting elements can then be arranged interleaved, and then to the corresponding connecting elements attached individually cut the tension element, for example, with an adhesive. Another way layout options headbands with alternating connecting elements are obvious 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 cell battery (included) is t, three second elongated connecting element and the second flat flexible component. The distance between the elongated connecting elements choose their rotation when pairing. However, the middle element of the second elongated connecting elements, being connected at both ends, prevents the pairing of the two other elements. To ensure the interface of two solid components, the specified average item cut, match these two components so that the elongated connecting elements are interleaved, and then restore the connection of the middle element. It is clear that this method of composition is also applicable to variants of headbands that have more than five elongated connecting elements.

Alternative options described with alternating connecting elements named as the bandage with a wide hole in the form of a keyhole. In the design of such bandage used two one-piece component made, for example, by way of cutting down. Each of the two solid components includes the first flat flexible component, the elongated connecting element or 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 elements onitake placed in the center of the dressing and next to each other. Elongated connecting elements of the second solid component are located on both sides of the connecting elements of the first solid component with an offset to the outside edges of the dressing. This construction facilitates the manufacture of bandages, since both one-piece component can be cut in the usual way, then the first solid component can be inserted in a relatively wide opening of the second solid component between the two sets of elongated connecting elements. When turning components for location in one plane corresponding to the superimposed state of the bandage, they clutch each other, resulting in a realized choice of dressings according to the present invention.

When applying the bandage to 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 and essentially parallel to the wound or incision. These edges are referred to as wound edges. In preferred embodiments of the present invention wound edges made with the possibility of screwing out out or raise the edges of the skin to facilitate wound healing. 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 to prevent the t eversion of the wound. This can be achieved, for example, the supply of wound edges of the strip. The strip may have an angular or arcuate shape. The adhesive layer on the lower parts of the flat flexible component also covers part of the wound edges. After dressing to the skin of this gut-wrenching edge strives to raise the edges of the skin in contact with it, thereby facilitates the healing of the wound or incision.

As mentioned above, the preferred variants of the present invention include variants of the bandage, manufactured using the process of cutting. In such embodiments, the elongated connecting elements appear in their dimensions in the form of straps. In preferred embodiments, in the elongated connecting elements are made slots to increase access to the wound or incision through the bandage that promotes the drainage of exudate and application of medicines. Such slots are preferably realized in the process of cutting.

In preferred embodiments, the bandage of the present invention is arranged to align wound closure. As mentioned above, the distance between adjacent elongated connecting elements is essential to align dressings for wound closure. In addition, in preferred embodiments, the bandage of the present invention provides indicators iraniansecurity wounds. These indicators are visual indicators positioned on a flat flexible components near the wound edge. These are usually in the form of a line or arrow pointing perpendicular to the wound or incision. The Clinician usually closes the wound with your fingers approximately at the midpoint, then surgical tassel makes a small mark or draws a line perpendicular to the wound. These marks are used when precise alignment of the alignment indicators provided on the bandage of the present invention.

The bandage of the present invention can also be implemented with the possibility of transdermal drug delivery. It is known that drugs are delivered through transdermal skin. For such applications, at least one flat flexible component attach the pad containing the drug, so that it can be delivered through the skin. Due to the lack of adhesive contact between the skin and the flat flexible component in the field of delivering the drug problems in this implementation with the transdermal delivery of drugs may be necessary to increase the size of the flat flexible component for securing bandages. Transdermal delivery of drugs with which edst well known, and for the implementation and use of specialist present invention overview of the field of prior art is not required.

The bandage of the present invention may further comprise an 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 the predetermined load. Similarly for this purpose can be used in other graphical representations. For example, the elastic element indicating the tension can be caused by a rectangle, which gives a graphical representation. Tensile element is a corresponding elongation of the rectangle. This element can be designed in such a way that the stretching of the original rectangle to the point where it is close to the geometric square means achieving the desired tension.

Although it is preferred that the flexible element indicating the tension was made with the possibility of removal together with the tensioning elements after dressing. At least an elastic element indicating the tension should be placed on the bandage so that when superimposed bandage he had no opportunities for further expansion and thereby dropping earlier oligotoma the desired tension.

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