(57) Abstract:

Usage: the invention relates to medical equipment and can be used in the manufacture of electrodes for removing the electrocardiogram. The essence of the invention: in the manufacture of electrodes for removal of the ECG on the surface of the base material (1), having a form of a sheet and performs rhythmic movement, paste labels (4), after which the metal connecting elements (6A, 6b) are connected with labels (4), then from the base material in the form of fabric (1) with pasted in the number of labels (4) and connecting elements (6A, 6b) form separate electrodes. Solid tape 4', which is applied to the layer of thermally activated adhesive, is led to the device for applying labels (10) in which the individual labels are cut one by one from a tape, and, accordingly heating an adhesive is applied on the base material (1). 2 S. and 19 C.p. f-crystals, 2 Il.

The invention relates to a method of manufacturing electrodes, including electrodes for removing the electrocardiogram, in which the surface of the base material, having a form of a cloth, paste labels, and connecting elements are connected with labels, and envelopes form, preferably cut, the individual electrodes, respectively, with one label and the connecting element. Further, the invention relates to a device for implementing this method.

All existing methods based on the use of such labels are self-adhesive layer. They need to be submitted, as they are self-adhesive on the base layer, and treated with silicone. Order these labels print, they must be pre-cut in a separate working step, and the corresponding lattice deleted. Tape labels put then in a device for the manufacture of electrodes around sharp edges, so the label bounces and can be pressed to the canvas. This method has some significant drawbacks. Positioning on the canvas material, in particular in the longitudinal direction cannot be met exactly. Error in pre-production tape for labels lead to errors on the canvas material. But especially important is the fact that outdoor self-adhesive layer is not in contact with the machine parts, because otherwise you may end up sticking. In particular, it is very important, if consistently pursued the course of the reaction support, which would stick the adhesive label.

The objective of the invention is to provide a method for manufacturing electrodes with high accuracy, and in addition, the device for implementing this method.

According to the invention, this problem is solved by the characteristics of p. 1 of formula (method) or p. 17 (device).

As a thermally activated adhesive suitable such, which becomes adhesive under the influence of heat, and if the temperature does not possess such properties. When cooled to normal temperature, these adhesives retain strong connections, however, are not glue in places where there is no such strong connections. For example, suitable adhesive in the molten state of matter, which previously from the melt is applied to the canvas for labeling. After application and cooling this melt processed in such a way onto labels are self-adhesive at room temperature, but when heated is thermally activated. Other thermally activated gluten can be a dispersion gluten. Here on the canvas for labeling before use in the claimed method on the m only under the influence of heat. In principle, it is possible to use other adhesives having a thermally activated properties.

The claimed method has several advantages: material-based is just below the hole punching machine for labels, cut labels is pressed, for example with an accuracy of 0.1 mm, to the heated surface and adheres to it. As a thermally activated adhesive immediately cools, it (unlike self-adhesive labels, which are always sticky) in the following technological positions is not sticky in open areas and can therefore come into contact with machine parts.

Another advantage is that the well-known self-adhesive labels can be obtained as a finished product by another manufacturer or can be made with high costs. Thanks to the use of thermally activated adhesive to the fabric, for example of PVC or other synthetic material, the layer of adhesive may be applied by the manufacturer of the electrodes using inexpensive way. Simplifies the process of storing, because for labels of different sizes and shapes can use the shadow them on the base material, having a form of a cloth, such as punching machine for labels. Thus, the storage of similar webs for labels is useful to obtain a large number of different labels.

Through the use of a thermally activated adhesive, which at room temperature are not adhesive, particularly advantageously possible to carry out the printing of the label of the device for the manufacture of electrodes. You only need to bring a solid color (for example white) tape, from which the labels are cut and applied on the base material, having a form of cloth. Next, labels instantly cools and can therefore easily Tiznit, and the lining, which is necessary for pressure and which is in contact with the adhesive through the hole in the material-based, not sticks together with the label, as it happens with self-adhesive labels. Thanks to the printing of labels in the machine itself, the process of storing even more simplified, because in the warehouse must be kept for labels, printed in a variety of ways, and only the neutral strip, on the bottom side which caused a thermally activated adhesive. "Printing" in accordance with the desires of the customers is tx2">

For applying labels to the base material, having a form of paintings, there are many opportunities. First, you can use a separate harvested the label on the underside of which is coated with the layer of thermally activated adhesive. To facilitate automatic feeding of labels is particularly advantageous, if the labels are served in the form of a continuous tape, which is below the coating in the form of a thermally activated adhesive. In this case there are two possibilities: either from a cloth just before gluing on the base material to form individual labels (for example by stamping are applied) and then paste these separate labels or labeling tape, paste a whole, and labels make only then, in particular, when the base material is cut or carve for formation of separate electrodes. Simultaneously with this process of cutting or die-cutting may be cutting or die-cutting from label canvas pasted on the base material.

The invention relates also to a device to implement the method with guide and transport device for the base material, having a form of fabric that is characterized by the fact that the cover is termoaktivirovannoe adhesives, and for applying them to the base material, and in the field of devices for applying labels is a heater for heating the adhesive.

Other advantages and details of the invention are given below in the description of the figures.

Fig. 1 shows a disassembled electrode, accurately and cost-effectively manufactured using the inventive method.

Fig.2 shows an example implementation of a device for implementing the inventive method.

It is shown in Fig. 1, the electrode has the base material 1, for example from foam, fabric or non-woven material. Material-based, having the form of a disk on the bottom is smokeasy layer 2, which, in turn, has a small coating on the edge. This is a small floor 3 allows you to easily remove the cover 4 which covers smokeasy layer 2 before application of the electrode and which is removed for the purpose of opening smokeasy layer 2 only before bonding the electrode to the skin of the patient.

Material-based, having the form of a disk, is in the middle of the hole 1a. This hole is closed on top by label 4, for example, of PVC or other plastics. Label 4 in the exemplary embodiment is connected to the base 1 by means of gluing in the molten coricnogo hold the connecting element, which represents in this case a metal rivet. The upper part 6A and the lower part of the rivet 6b are connected to each other through the label and thus occupy a fixed position. Under the rivet is spongy material 7, which tends to adhere to the molten adhesive 5. The spongy material 7 is impregnated in a known manner conductive gel for electric transmission capacity.

In Fig. 2 shows an example implementation for implementing the inventive method of manufacturing electrodes, including electrodes for removal of the ECG. Unwinding from the reel 8 material-based in the form of a tape is moving in Fig.2 from left to right through the device. Is rhythmic transportation, and known, by themselves, guiding and transporting device not shown. Material-based, for example, consists of foam, nonwoven or similar width 35-80 mm and having samoklejushchiesja cover, lower smokeasy layer covered by a paper treated with silicone. Using a punching stamp 9 material basis in mid-punch round hole, the size of, for example, 15-25 mm.

According to the claimed method, a continuous strip 4', covered with a layer of thermally activated prophetic is a specific example of a device for labeling performed as punching device 10, which carve on canvas 4' one after the other labels 4 and during technological operations presses the material basis. In order to obtain bonding in the field of devices for applying labels 10 need heating adhesive located on the bottom side of the label, because this substance at room temperature is not a glue. For this purpose a heater 11 for heating the base material 1 from below. Thanks adhesive in the molten state of matter is a reliable adhesion to a material basis. Thanks to stanziani and subsequent pinning possibly extremely accurate positioning of the labels on the material basis. In subsequent processing position, the pressing pad 12 is glued to the material on the basis of 1 the label is pressure. It is particularly advantageous that due to the appropriate distance between the position of the pressure 12 and a device for applying labels 10, and through the inlet of the transportation speed of the base material can be achieved, so that the adhesive in the molten state of the substance at the position of the push 12 was no longer sticky. Thus, the exposed areas containing substance, also can not stick together with the basis of which admission is a large number, as each order must be provided with a large number of labels for replacement, if necessary, possible defective items. In the proposed method, the printing may occur sequentially, the number of labels corresponds exactly to ordered, when the change order does not change the canvas for labels, and only printing cliche.

In the following technological position 13 (position klenke) items 6A and 6b rivets are connected to each other through the label 4 and later form electrical connecting element. There is also a big advantage is that the layer of adhesive in the molten state of matter in this case is not sticky. The next step should be a connection spongy material 7 with the label 4 in the corresponding stamp 14 below. As the adhesive in the molten state, the substance is not adhesive at room temperature, before the stamp 14 has a heating device 15, from which the heated air comes out and heats the exposed areas of adhesive located on the bottom side of the label 4, and thus provides the possibility of gluing. Due to the small distance between technological positions 15 and 14 nagrevayetsya porous material 7 and labels 4.

Then known by itself, the operation of soaking a piece of spongy material 7, glued with label 4, when applying gel 16. Thus, the electrodes are ready. Then with the bottom side of the base material in the form of cloth is removed, treated with silicone paper film 1A, and the outdoor therefore, smokeasy layer is supplied with treated silicone tape that already has a cell for receiving the impregnated pieces of porous material 7. This tape is indicated by numeral 17.

The last step in the final stamp 18 of the finished electrodes are cut from the base material, having a form of cloth. They fall out of the device in the direction of the arrow 19.

Instead of the above-described adhesive with molten substance may also be used and other thermally activated adhesive, for example, dispersion adhesives, which at room temperature have no adhesive properties, and become adhesive under the action of heat.
