FIGS. 2 and 3 show examples of conventional biological stimulation electrodes that are generally used, and of these figures, A is a perspective view, and B is a sectional view of the electrode in use. Third
In the example shown in the figure, the biological stimulation electrode 1 includes an electrode main body 2 made of an insulating material having a horizontally elongated hole 2 1 on the upper side and electrodes 3 1 and 3 2 on the lower surface, and an electrode body 2 on the upper side of the electrode main body 2. It is composed of a grip part 4 consisting of a vertical part 4 1 and a horizontal part 4 2 integrally formed, and a lead wire 5 for connecting an electrode to a medical device. The hole 2 1 is elongated in the lateral direction corresponding to the cross-sectional shape of the belt 6 in order to pass the fixing belt 6 therethrough. Electrode 3 1 and 3 2
is electrically connected to the lead wire 5 within the electrode main body 2 .

During use, if you want to fix it to a specific body part, such as your arm, you can fix it by passing the fixing belt 6 through the hole 21 of the electrode main body 2 and wrapping it around the arm 7 several times as shown in Figure 3B.

た。 The example shown in FIG. 2 shows an electrode main body 2 and a grip 4 that are detachable. A male screw portion 4a is formed at the lower end of the grip portion 4, and a corresponding female screw portion 4b is formed on the upper surface of the electrode main body portion 2, so that it can be attached and removed. When fixing the electrode main body part 2 to a living body, the grip part 4 was turned and removed, and as shown in FIG. 3B, the electrode body part 2 was fixed in the same manner as in FIG. 3B.

In the example shown in FIG. 3, when fixing the living body stimulation electrode 1 to a specific part of the living body, the electrode main body 2 and the gripping part 4 are integrally formed and cannot be removed, so the gripping part 4 as shown in FIG. The fixing belt 6 had to be wound around the living body from above the living body, and the height at the time of fixation was large and unstable. For this reason, even the slightest movement of the living body tends to cause agitation, and the contact area or pressing force of the electrodes 3 1 and 3 2 against the living body becomes uneven, which may cause noise during measurement or accurate identification of current during electrical stimulation. It was not possible to stimulate the body part, and the current density was concentrated locally, causing pain to the living body. Particularly in the case of infants and the like, because they are active, the disturbance caused by the above-mentioned agitation is significant.

把持部4を電極本体部2に固定できなくなること
もあつた。更に、着脱時に把持部4を回す必要が
あり、取扱いに時間を要する等の不都合な点もあ
つた。 The example shown in Figure 2 improves the above drawback by making it possible to remove the grip part 4 from the electrode main body 2 with a screw. The stability is better than that shown in FIG. 3 because it is lower. However, such a structure requires the formation of a threaded portion, which increases the number of manufacturing steps and increases costs. In addition, the threaded portion was sometimes worn out, making it impossible to fix the gripping portion 4 to the electrode main body portion 2. Furthermore, it is necessary to turn the grip part 4 when attaching and detaching, which is inconvenient and requires time to handle.
したがつて、本考案は、電極本体部と把持部を
ただ1回の操作で着脱できる簡単な構造の取り扱
い易い生体刺激用電極を提供しようとするもので
ある。 Therefore, the present invention aims to provide a biostimulation electrode that has a simple structure and is easy to handle, in which the electrode body and the gripping part can be attached and detached with just one operation.

In the present invention, a notch is provided on the upper side of the hole in the electrode body, and a horizontal part is provided in the gripping part to correspond to the hole, and the horizontal part and the vertical part of the gripping part fit into the hole and the notch with a slight pressing force. I made it possible.

Figure 1 shows an embodiment of the present invention.
1 is an exploded perspective view showing a state before the electrode main body 2 and the gripping part 4 are fitted together, and FIG. In FIG. 1, parts corresponding to those of the conventional example in FIG. 3 are given the same numbers. Horizontally long hole 2 in electrode body 2
A notch 2 3 is provided at approximately the center of the upper side 2 2 of the hole 2 1 in a direction approximately perpendicular to the longitudinal direction of the hole 2 1 . Gripping part 4
In addition to the vertical part 4 1 and the horizontal part 4 2 , another horizontal part 4 3 corresponding to the hole 2 1 is provided, and the cross section is made into an E-shape. The thickness of the horizontal part 4 3 below the grip part 4 is the hole 2 1
The vertical gap is slightly larger than that of hole 2, and its length is
Make it shorter than the horizontal (longitudinal) length of 1 . The thickness of the vertical portion 4 1 is made smaller than the width of the notch 2 3 (the gap in the longitudinal direction of the hole 2 1 ). If the shapes of the upper and lower horizontal portions 4 2 and 4 3 are substantially the same, there is an advantage that the grip portion 4 can be used without distinction between the upper and lower portions.
