  By the way, in any of the conventional biomedical electrode pads as described above, in order to make good electrical contact between the adhesive conductive gel 3 and the skin surface before being attached to the skin surface, the electrode on the skin surface is used in advance. It is necessary to perform a skin treatment such as wiping the mounting site with alcohol cotton as a degreasing agent and then lightly boiling with sandpaper as an abrasive. However, in the actual medical field, since the medical staff is extremely busy, such skin treatment has not been thoroughly performed, and there are many cases where electrocardiograms or electromyogram data are not stably measured.

  The present invention advantageously solves the problems of the conventional biomedical electrode pad, and the biomedical electrode pad of the present invention includes an electrode for detecting a bioelectric signal, an adhesive conductive gel covering the electrode, A release sheet that covers the adhesive conductive gel when the electrode is not used, and the adhesive conductive gel is a biological electrode pad that is peeled off when the electrode is used and is attached to the skin of a living body. The skin treatment sheet is inserted between the release sheet and the adhesive conductive gel so as to face at least a part of the surface opposite to the side facing the electrode, so that the skin treatment sheet can be pulled out. It is characterized in that at least one of a degreasing agent and an abrasive is fixed to the surface of the sheet facing the release sheet.

  In such a biomedical electrode pad, when being applied to the surface of the skin, first, an electrocardiograph or the like is connected to the connection terminal via an electric cable, and the release sheet is peeled off to remove the adhesive conductive gel and the skin treatment. The sheet is exposed, and then the adhesive sheet of the adhesive conductive gel that is not opposed to the skin treatment sheet or the adhesive sheet surrounding the adhesive conductive gel is pressed against the skin surface of a predetermined part of the living body, and is applied. The skin treatment sheet is sandwiched between the adhesive conductive gel and the skin surface. Then, when the skin treatment sheet is pulled out from between the adhesive conductive gel and the skin surface in that state, the degreasing agent and the polishing agent fixed to the surface of the skin treatment sheet that is initially opposed to the release sheet and is opposed to the skin surface are then polished. At least one of the agent moves on the skin surface together with the skin treatment sheet while being pressed against the skin surface with the adhesive conductive gel, and performs skin treatment to improve electrical contact on the skin surface. Thereafter, the part of the adhesive conductive gel exposed by extracting the skin treatment sheet is pressed against the skin surface and pasted.

  Therefore, according to the biomedical electrode pad of the present invention, there is no need to perform skin treatment such as wiping the electrode mounting site on the skin surface with alcohol cotton or lightly stroking with sandpaper beforehand. Since skin treatment can be performed with at least one of a degreasing agent and an abrasive provided in the biomedical electrode pad when attached, an electrocardiogram or electromyogram data, etc. in a medical site where medical personnel are extremely busy Can always be measured stably.

  In the biomedical electrode pad of the present invention, the degreasing agent and the abrasive may be aligned and fixed in the drawing direction on the skin treatment sheet. In this way, when the biological electrode pad is attached, the skin treatment can be sequentially performed with the degreasing agent and the abrasive provided in the biological electrode, so that the skin treatment can be made more effective. Here, the degreasing agent and the abrasive may precede each other in the drawing direction of the skin treatment sheet, but it is more preferable to first degrease the skin surface with the degreasing agent and then roughen the skin surface with the abrasive. .

  In the biomedical electrode pad of the present invention, the skin treatment sheet is folded in the middle so that one end of the skin treatment sheet faces the adhesive conductive gel with respect to the folded portion and the other end side with respect to the folded portion May be opposed to the release sheet, and at least one of the degreasing agent and the abrasive may be fixed to the other end side. In this way, the skin treatment sheet can be pulled out without being brought into sliding contact with the adhesive conductive gel, so that the skin treatment sheet can be easily pulled out and the surface of the adhesive conductive gel can be prevented from being rough. .

  Furthermore, in the biomedical electrode pad of this invention, the said skin treatment sheet may extend across the center part of the said adhesive conductive gel. In this way, the skin treatment sheet can be pulled out from the central portion of the adhesive conductive gel with both sides of the adhesive conductive gel attached to the skin surface and the bioelectrode positioned, so that the skin treatment sheet can be easily pulled out. Can be.

It shows with the same code | symbol.

  As shown in FIG. 1, the biomedical electrode pad of this embodiment includes an electrode 1 having a plate-like collar portion 1a and a connecting terminal 1b protruding from the central portion thereof, as in the conventional example shown in FIG. The surface of the base material made of, for example, plastic that forms the flange portion 1a and the connection terminal 1b is covered with silver plating or silver chloride coating, which is a highly conductive metal, and the connection terminal 1b of the electrode 1 The protective sheet 2 made of a conductive material is inserted into the central hole 2a of the central portion from the back side and protrudes to the front side of the protective sheet 2, and the back surface of the protective sheet 2 is, for example, directly or via a double-sided adhesive tape not shown. And the sheet-like adhesive conductive gel 3 is affixed so that the collar part 1a may be covered.

  In this embodiment, however, a skin treatment sheet 8 made of, for example, the same material as that of the release sheet 4 is stacked so as to extend across the central portion of the adhesive conductive gel 3 and face the adhesive conductive gel 3. The adhesive conductive gel 3 is attached to both sides not covered with the skin treatment sheet 8 so as to cover and protect the entire adhesive conductive gel 3 when the electrode pad is not used. A release sheet 4 made of a normal film that has been subjected to a surface treatment that is easily peeled off from the conductive gel 3 is provided.

  The skin treatment sheet 8 inserted between the adhesive conductive gel 3 and the release sheet 4 in this way is folded back at an intermediate portion thereof, and one end portion 8a overlaps with one end portion 3a of the adhesive conductive gel 3. The folded portion 8b protrudes from the other end portion 3a of the adhesive conductive gel 3, and the other end portion 8c is disposed so as to protrude from the one end portion 3a of the adhesive conductive gel 3 as a puller.

  2 (a) to 2 (d) show how to use the biomedical electrode pad of this example over time, and when the biomedical electrode pad of this example is applied to the surface of the skin, FIG. First, an electrocardiograph or the like is connected to the connection terminal 1b via an electric cable, and as shown in FIG. 2 (a), the release sheet 4 is peeled off to remove the adhesive conductive gel 3 and the skin treatment sheet 8. As shown in FIG. 2 (b), both sides of the adhesive conductive gel 3 not facing the skin treatment sheet 8 (not covered with the skin treatment sheet 8) are exposed to the skin of a predetermined part of the living body. The skin treatment sheet 8 is sandwiched between the adhesive conductive gel 3 and the skin surface S by being pressed against the surface S and pasted.

  In this state, as shown in FIG. 2C, when the other end 8c of the skin treatment sheet 8 is pulled and the skin treatment sheet 8 is pulled out between the adhesive conductive gel 3 and the skin surface S, The degreasing agent 9 and the abrasive 10 fixed to the surface of the skin treatment sheet 8 that is initially opposed to the release sheet 4 and that opposes the skin surface S, together with the skin treatment sheet 8, are adhesive conductive gel 3. The skin surface is moved by moving on the skin surface S while being pressed against the skin surface S, first degreased with the degreasing agent 9, and then subjected to skin treatment to roughen the skin surface S with the abrasive 10. The electrical contact of S is improved. At this time, the folded portion 8b gradually moves between the adhesive conductive gel 3 and the skin surface S while making a transition on the skin treatment sheet 8 so as to approach the one end portion 8a. When it comes out between the gel 3 and the skin surface S, it disappears. After that, as shown in FIG. 2 (d), the remaining portion of the adhesive conductive gel 3 exposed after the skin treatment sheet 8 is extracted is pressed against the skin surface S and pasted.

  Further, according to the biomedical electrode pad of this embodiment, the skin treatment sheet 8 is folded back in the middle so that the one end 8a side faces the adhesive conductive gel 3 with respect to the folded portion 8b and the folded portion 8b. Since the other end 8b is opposed to the release sheet 4 and the degreasing agent 9 and the abrasive 10 are fixed to the other end 8b, when the skin treatment sheet 8 is pulled out, the folded portion 8b While the portion on the one end 8a side is adhered to the adhesive conductive gel 3, the portion on the other end 8b side is in sliding contact with the portion on the one end 8a side and the skin surface S with respect to the folded portion 8b. Since it gradually moves between the adhesive conductive gel 3 and the skin surface S while making a transition on the skin treatment sheet 8 so as to approach the one end 8a, the skin treatment sheet 8 is brought into sliding contact with the adhesive conductive gel 3. Without It can be pulled out, thereby preventing the roughening of the with adhesive conductive gel third surface to facilitate withdrawal of the skin processing sheet 8.

  Furthermore, according to the biomedical electrode pad of this embodiment, since the skin treatment sheet 8 extends across the central portion of the adhesive conductive gel 3, both side portions of the adhesive conductive gel 3 are applied to the skin surface S. Since the skin treatment sheet 8 is pulled out from the central portion of the adhesive conductive gel 3 with the biomedical electrode pad positioned, the skin treatment sheet 8 can be easily pulled out.

  3 (a) and 3 (b) are perspective views showing another embodiment of the biomedical electrode pad of the present invention from the front side and the back side, respectively, and FIGS. 4 (a) and 4 (b) are views of the above embodiment. It is a disassembled perspective view which shows the structure of the biomedical electrode pad, and the half part sectional view which shows the flexible substrate periphery, In the figure, a part is shown with the same code | symbol as it like the prior art example shown in FIG.

It is arranged so that it overlaps with one end portion 3a of the gel 3, the folded portion 8b protrudes from the other end portion 3a of the adhesive conductive gel 3, and the other end portion 8c protrudes from the one end portion 3a of the adhesive conductive gel 3 as a puller. ing.

  And the degreasing agent 9 which consists of the nonwoven fabric etc. which impregnated alcohol etc. in the surface which opposes the peeling sheet 4 of the part between the folding | turning part 8b and the other end part 8c of this skin treatment sheet 8, and fine An abrasive 10 made of solid particles or the like is bonded and fixed so as to be aligned in the longitudinal direction of the skin treatment sheet 8 and to extend in a strip shape over the entire width of the skin treatment sheet 8.

  In use of the biomedical electrode pad of this embodiment, first, an electrocardiograph or the like is connected to the connection terminal 1b via an electric cable, and the release sheet 4 is peeled off to release the adhesive conductive gel 3 and the skin treatment sheet. 8 and the adhesive surface of the adhesive sheet 7 are exposed, and then the adhesive sheet 7 located on both sides of the adhesive conductive gel 3 is not opposed to the skin treatment sheet 8 (not covered with the skin treatment sheet 8). Both side portions are pressed against and adhered to the skin surface S of a predetermined part of the living body, and the skin treatment sheet 8 is sandwiched between the adhesive conductive gel 3 and the skin surface S.

  In this state, when the skin treatment sheet 8 is pulled out from between the adhesive conductive gel 3 and the skin surface S, the skin treatment sheet 8 is initially opposed to the release sheet 4 and then the skin surface S, as in the previous embodiment. On the skin surface S, the degreasing agent 9 and the abrasive 10 fixed to the surface of the skin treatment sheet 8 that opposes the skin surface are pressed against the skin surface S by the adhesive conductive gel 3 together with the skin treatment sheet 8. The skin surface S is first degreased with the degreasing agent 9, and then the skin treatment is performed to roughen the skin surface S with the abrasive 10, whereby the electrical contact of the skin surface S is improved. Thereafter, the remaining portions of the adhesive conductive gel 3 and the adhesive sheet 7 that are exposed when the skin treatment sheet 8 is extracted are pressed against the skin surface S and pasted.

  Therefore, according to the biomedical electrode pad of this embodiment, the skin treatment such as wiping the electrode mounting portion of the skin surface S in advance with alcohol cotton or lightly stroking with sandpaper is not performed as in the previous embodiment. However, since the skin treatment can be performed with the degreasing agent 9 and the polishing agent 10 included in the biomedical electrode pad when the biomedical electrode pad is mounted, the medical staff is extremely busy at the medical site where the implementation is extremely busy. Electrocardiogram or electromyogram data can be always measured stably.

  In addition, according to the biomedical electrode pad of this example, the degreasing agent 9 and the abrasive 10 are aligned and fixed in the drawing direction on the skin treatment sheet 8 as in the previous example. Since the skin treatment can be performed in the order of degreasing and then polishing with the degreasing agent 9 and the abrasive 10 provided in the biomedical electrode pad at the time of wearing, the skin treatment can be made more effective. .

  Further, according to the biomedical electrode pad of this example, the skin treatment sheet 8 is folded in the middle, and the one end 8a side is opposed to the adhesive conductive gel 3 with respect to the folded part 8b, as in the previous example. When the skin treatment sheet 8 is pulled out, the other end 8b is opposed to the release sheet 4 with respect to the folded portion 8b, and the degreasing agent 9 and the abrasive 10 are fixed to the other end 8b. In addition, while the portion on the one end 8a side is adhered to the adhesive conductive gel 3 with respect to the folded portion 8b, the portion on the other end 8b side on the folded portion 8b and the portion on the one end 8a side and the skin surface S The slidable contact and the folded portion 8b gradually move between the adhesive conductive gel 3 and the skin surface S while moving on the skin treatment sheet 8 so as to approach the one end 8a.

The adhesive conductive gel 3 can be surrounded by the adhesive sheet 7 and can be reliably maintained on the skin surface S while being able to adhere firmly to the surface S.

  As mentioned above, although demonstrated based on the example of illustration, this invention is not limited to the above-mentioned example, It can change suitably within the description range of a claim, For example, the skin treatment sheet 8 is adhesive. The conductive gel 3 may extend from the center to the outside through one side. In this case, the other side of the adhesive conductive gel 3 is attached to the skin surface S to position the bioelectrode. In this state, the skin treatment sheet 8 is pulled out from the one side portion of the adhesive conductive gel 3, so that the skin treatment sheet 8 can be pulled out to some extent.

  Further, in the biomedical electrode pad of the present invention, the skin treatment sheet 8 is not provided with the folded portion 8b so that the surface of the adhesive conductive gel 3 can easily slide on the surface of the skin treatment sheet 8 facing the adhesive conductive gel 3. For example, surface treatment such as Teflon may be performed, and the skin treatment sheet 8 may be pulled out while being in sliding contact with the adhesive conductive gel 3 and the skin surface S. In the biomedical electrode pad of the present invention, only one of the degreasing agent 9 and the abrasive 10 may be fixed to the skin treatment sheet 8, or the arrangement of the degreasing agent 9 and the abrasive 10 is reversed. It may be provided.

  Thus, according to the biomedical electrode pad of the present invention, it is possible to attach the biomedical electrode pad in advance without performing skin treatment such as wiping the electrode mounting site on the skin surface with alcohol cotton or lightly stroking with sandpaper. Since the skin treatment can be performed with at least one of a degreasing agent and an abrasive provided in the biomedical electrode pad, the electrocardiogram or electromyogram data can be obtained at a medical site where the medical staff is extremely busy. It can always measure stably.
