The present invention relates to a pad for a biostimulation electrode, in particular a pad applicable to a biostimulation electrode integrated with a small low-frequency therapy device.

In general, a bioelectrode refers to a conductor which contacts an organism and guides an electrical phenomenon or an electrical stimulus, and there are two kinds thereof.

In other words, there are bioinduction electrodes for inducing electrical phenomena in vivo and, on the contrary, biostimulation electrodes for introducing electrical stimuli from outside.

For example, the bioinduction electrode is used to derive the potential of two points on the surface of the living body from the living body and input it to the electrocardiograph to output the electrocardiogram. It is introduced in the stomach and is used to relax muscles and neuralgia.

However, it is not preferable to bring any of the above electrodes into direct contact with a living body for the following reason.

That is, since the electrode plate constituting the electrode is made of metal, it is difficult to adhere closely to the skin surface of the living body, and it is difficult to accurately guide the electrical phenomenon or electrical stimulation due to the contact resistance generated between the skin surface of the living body and the electrode plate. Because many patients use it, contamination of pathogens and skin adheres to the electrode, which is unsanitary, and infection becomes a problem.

For this reason, as shown in FIG. 6, neither the bioinduction electrode nor the biostimulation electrode, the electrode plate 20 connected to the medical device 10 such as the electrocardiograph or the low frequency treatment device, and the electrode plate 20 It is composed of a pad 30 that can be attached to. The pad 30 is made of a conductive and adhesive hydrous gel layer, and in use, one surface 42 is brought into contact with the electrode plate 20 while the other surface 41 is placed on the skin surface 50 of the living body. ) Is intended to be in close contact.

That is, the bioelectrode is constituted by a pad formed of a hydrous gel layer having both conductivity and adhesiveness in addition to the electrode plate. By making the pad detachable with respect to the electrode plate, the above points 1 to 3 are simultaneously overcome.

The present invention relates to a pad for a biostimulation electrode that can be adapted to a small low-frequency therapy device, particularly a pad having such significance.

In the conventional low frequency therapy apparatus, as shown in FIG. 7A, the first electrode plate 5 and the second electrode plate are provided at the tip ends of two pad cords 8 and 9 connected to the main body 7. (6) is attached.

In each of these two electrode plates 5 and 6, the first pad 1 and the second pad 2 are detachable.

When the low frequency treatment device is used, the first electrode plate 5 and the first pad 1 and the second pad 2 are accommodated in the first recess 5A and the second recess 6A. After the adhesion to the second electrode plate 6, the surface is brought into close contact with, for example, the skin surface of both shoulders.

However, with the miniaturization of electronic components, the low frequency treatment devices described above have also been shifted from large ones to small ones. In recent years, portable small low frequency treatment devices have been proposed as shown in FIG. 7B.

This small low frequency therapy device is such that the first electrode plate 5 'and the second electrode plate 6' are mounted directly on the main body 7 without intervening the padcodes 8 and 9a. It is.

In other words, in the small low-frequency therapy apparatus, the semicircular first electrode plate 5 'and the second electrode plate 6' constituting the biostimulation electrode are integrally disposed with the main body 7 'and disposed adjacent to each other.

With respect to the first electrode plate 5 'and the second electrode plate 6' as described above, the first pad 1 'and the second pad 2' corresponding to them are detachable.

However, the small pads 1 'and 2' must be detached from the electrode plates 5 'and 6' separately each time they are used, and the detachable operation is performed twice. This is very cumbersome for the user.

In addition, each small pad 1 'and 2' is directly gripped with a finger at each detachment operation and accommodated in each recess 5A 'and 6A' or taken out therefrom. Since (1 '), (2'), and corresponding recessed parts (5A ') and (6A') are about the same size, it becomes very difficult operation. This is because the hydrogel layer constituting the both pads 1 'and 2' is sticky, so that the finger and the hydrogel layer are in close contact with each other. Therefore, it takes time to adhere the pads 1 ', 2' to the electrode plates 5 ', 6'.

In addition, since a small pad is directly held by a finger, dirt or dust attached to the finger adheres to the entire hydrogel layer and loses conductivity and adhesion.

In short, conventionally, since two small pads are formed separately even if the corresponding pads are detached from the two electrode plates of the small low-frequency treatment device, the detachable operation itself is also used in terms of the number of detachable operations. Even, there was a problem that requires time and effort.

An object of the present invention is to easily and quickly perform the detachable operation of the pad for a biostimulation electrode with respect to a small low frequency therapeutic apparatus.

The problem is that the first pad comprising the conductive and tacky first bio-side hydrogel layer and the first electrode-side functional gel layer by sandwiching one side of the insulating base sheet, and the other side of the insulating base sheet, A second pad composed of a conductive and tacky second bio-side hydrogel layer and a second electrode-side hydrogel layer is integrally mounted with the small low frequency therapeutic base to be adjacent to the adjacent first electrode plate and the second electrode plate. Correspondingly disposed, respectively, the central portion of the insulating base sheet is continuously exposed throughout the entirety between the first pad and the second pad, and the gripping surface protrudes toward the outside of the first pad and the second pad. It is solved by a pad for a biostimulation electrode, characterized in that the present.

As described above, in the present invention, as shown in FIG. 1, the insulating substrate sheet (1) corresponds to the first electrode plate 500 and the second electrode plate 600 of the small-frequency treatment basic body 700. On one side 310 and the other side 320 of 300, the first pad 100 and the second pad 200 are disposed, respectively, and are insulated over the entire area between the pads 100 and 200, respectively. The central portion 330 of the base sheet 300 is continuously exposed.

Therefore, both pads 100 and 200 are connected in an insulating state via the insulating base sheet 300.

In addition, as apparent from FIG. 1, in the present invention, the gripping piece 400 protrudes toward the outside of the pads 100 and 200.

For this reason, when the grip piece 400 is gripped with a finger, the first and second pads 100 and 200 which are connected to each other in an insulated state are not directly touched. And the second electrode plates 500 and 600 can be attached and detached at the same time.

Therefore, both in terms of the number of times of detachable operation and in terms of the detachable operation body, the labor and time are much smaller than before.

As described above, according to the present invention, the detachable operation of the pad for the biostimulation electrode can be easily and quickly performed with respect to the small low frequency therapy apparatus.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

2 is a diagram showing a first embodiment of the present invention. In Fig. 2A, reference numeral 100 denotes a first pad, 200 denotes a second pad, and 300 denote an insulating substrate.

The first and second pads 100 and 200 correspond to the adjacent first and second electrode plates 500 and 600 integrally formed with the small low frequency treatment main body 700 ( 1), respectively. Since the first and second electrode plates 500 and 600 have a disk shape in this embodiment, both pads 100 and 200 are also formed in a semi-circular shape which is generally flat in correspondence thereto.

The insulating base sheet 300 is formed of a porous member such as a fabric base, a knitting base, a nonwoven fabric, and has a disc shape. The first pad 100 is a conductive and tacky first biological side sewage gel layer 110 and a first electrode side functional gel layer 120 which sandwich one side 310 of the insulating base sheet 300. It is formed of two layers structure. The first biological side function gel layer 110 can be adhered to the skin surface of the living body, and the first electrode side functional gel layer 120 can be adhered to the electrode plate surface. As shown in FIG. 2B, the holes 311, 312,... Of the one side 310 of the insulating base sheet 300 are provided. The first functional gel column 113 penetrates through. (114)... By this, they are mutually connected and are electrically connected. Also for the second pad 200, the conductive and sticky second bio-side functional gel layer 210 and the second electrode-side functional gel layer 220 sandwich the other portion 320 of the insulating base sheet 300 to each other. The point of coupling is only different from that of the first pad 100, and as is apparent from Figs. 2a and b, the components themselves are exactly the same as the first pad 100.

Between these pads 100 and 200, the center part 330 of the insulating base sheet 300 is exposed continuously throughout. That is, the pads 100 and 200 are opposed to each other via the exposed central portion 330 and are connected in a completely insulated state.

In addition, both ends of the exposed center portion 330 protrude toward the outside of the pads 100 and 200, and the protruding portions of the first and second gripping pieces 410 and 420 are formed. The holding piece 400 is formed.

The first and second gripping pieces 410 and 420 are bent when the two pads 100 and 200 are mounted on the small low frequency treatment body 700, as shown in FIG. 2C. The outer surface 710 can be adhered to.

Thereby, the pads 100 and 200 according to the present invention have an effect of being in close contact with the body skin surface together with the body 700. In other words, only the main body 700 is separated from the pads 100 and 200 to prevent it from falling off.

Next, a second embodiment of the present invention shown in FIG. 3 will be described.

The first embodiment (FIG. 2) differs from the forming member of the insulating base sheet 300, and a joining means between the biological side functional gel layer and the electrode side functional gel layer.

That is, the insulating base sheet 300 in the second embodiment is formed of a member having no holes, for example, rubber ground and resin ground.

Accordingly, the first bio-side functional gel layer 110 and the first electrode-side functional gel layer 120 also, for example, along the end surface 311 of one side 310 of the insulating base sheet 300 made of rubber based material. Integrally coupled to one another (figure 2a, b).

The coupling means is completely the same with respect to the second biological side functional gel layer 210 and the second electrode side functional gel layer 220 (FIGS. 2A and 2B).

Hereinafter, the effect | action of this invention which has the said structure is demonstrated based on FIG.

First, one of the gripping pieces 400, for example, the first gripping piece 410 is picked up with two fingers, and the first and second electrode side function gel layers 120 and 220 are turned downward, and the small low frequency Both gel layers 120 and 220 are disposed on the first and second electrode plates 500 and the plate 600 in the first recess 500A and the second recess 600A of the treatment body 700, respectively. Glue.

Thus, the pads 100 and 200 can be adhered to the positive electrode plates 500 and 600 at the same time without directly touching the pads 100 and 200. Further, the first gripping piece 410 and the second gripping piece 420 are folded and bent to adhere to the outer surface 710 of the main body 700 (FIG. 2C).

In this state, the small low frequency therapeutic body 700 equipped with both pads 100 and 200 is held in the hand, for example, the first and second recesses on the skin surface of the hand and the foot of the human body. The first and second biological side function gel layers 110 and 210 exposed from 500A and 600A are brought into close contact with each other. Thereby, the pads 100, 200, and the main body 700 are in close contact with the living body, and do not fall off during treatment.

When the treatment is finished, together with the small low-frequency treatment main body 700, the gel layers 110, 210 are peeled off to the skin surface and at the same time, both gripping pieces 410 and 420 are folded back from the body outer surface 710. Peel off, the first gripping piece 410 is again picked up with two fingers, and the first and second electrode side function gel layers 120 and 220 are respectively placed on the first and second electrode plates 500 and 600. ) Thereby, the operation of removing the pads 100 and 200 from the positive electrode plates 500 and 600 can also be performed simultaneously in one hand without being directly touched.

Such a pad for a biostimulation electrode according to the present invention having an action effect can be produced, for example, by the following method.

That is, as shown in FIG. 5, when the stock solution of the acrylic functional gel having conductivity and adhesiveness penetrates through the hole from the upper surface of the insulating base sheet 300 of warp knit base material, the acrylic system is also formed on the lower surface thereof. The stock solution of the hydrous gel leaks out.

Therefore, when the stock solution is solidified by ultraviolet treatment or the like, a bio-side functional gel layer and an electrode-side functional gel layer which sandwich the insulating base sheet 300 are formed. For this reason, as shown in the drawing, if two layers of the hydrogel layer sandwiching the insulating base sheet 300 are formed in the boundary where the base sheet is exposed, and a few rows are formed, they are extracted by punching or the like as a dashed line. The pad for a biostimulation electrode according to the present invention can be manufactured as much as possible.

As described above, in the present invention, the first pad made of the conductive and tacky first biological side functional gel layer and the first electrode side functional gel layer sandwiched with one side of the insulating base sheet, and the insulating base sheet A second pad composed of a conductive and tacky second bio-side functional gel layer and a second electrode-side functional gel layer, which are held together by interposing the other portion, is mounted integrally with the small-sized low-frequency treatment main body to adjoin the first electrode plate and the first. Corresponding to the two electrode plates, respectively, the center portion of the insulating base sheet is continuously exposed throughout the entirety between the first pad and the second pad, and held toward the outside of the first pad and the second pad. Technical measures have been taken that the side is protruding.

For this reason, the first and second pads disposed in correspondence with the first and second electrode plates of the small low-frequency treatment main body are interconnected in an insulated state, and when the grip pieces are held, both pads are directly held in the hand. Without attaching, the two electrode plates can be attached and detached at the same time.

Therefore, the technical effect that the detachable operation of the pad for a biostimulation electrode is performed easily and quickly with respect to a small low-frequency therapy device is brought.

In addition, if the pad for the biological stimulation electrode is composed of a hydrogel layer having both conductivity and adhesiveness, the gripping piece can be folded and adhered to a small low frequency therapy device even when it is mounted in the same manner. The pad can be adhered to the surface of the skin, and since the bio-side functional gel layer and the electrode-side functional gel layer forming the pad are bonded to each other by sandwiching one side and the other side of the insulating base sheet, even when peeling from the electrode plate. These one-layered gel layer is made of one body, and can be easily removed and detached, and the pad of the present invention also has a side effect of not drying for a long time.
