Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a medical clip electrode.

[Conventional technology]

For example, conventional medical clip electrodes include
There is something published in Publication No. 8834.

The above-mentioned medical clip electrode is connected to a button electrode attached to the body by a pair of electromagnetic clamping pieces fixed to the tip of the clip. The clip part that holds the clamping piece is composed of an operating member made of hard synthetic resin and an extensible part made of soft synthetic resin that covers the entire operating member, and the clamping piece is opened and closed from a connecting fulcrum piece formed on the operating member. There is.

[Problem that the invention attempts to solve]

The conventional medical clip electrodes described above not only have a complicated structure, but also require materials such as magnets, hard synthetic resins, and soft synthetic resins, making manufacturing time-consuming and costly. In addition, there are problems such as difficulty in using it for small children who are not large and heavy.

The object of the present invention is to solve the above-mentioned problems and to provide a medical clip electrode that has a very simple structure, is suitable for mass production, is small and lightweight, and is optimal for infants.

[Means for solving problems]

The technical means of the present invention is to form a clip body 1 in the shape of a substantially circular frame from a soft synthetic resin, and a pair of clamping pieces 4, 5 formed from metal plates on the thick walled parts 2, 3 arranged opposite to each other on the left and right inner sides of the clip body 1. The bent bases 4a, 5a of the two are embedded and fixed, and the conducting wire 6 is connected to one of the bent bases 5a, and the arc-shaped recessed tips 4b, 5b provided on each clamping piece 4, 5 are connected to the button electrode a. protrusions 8, 8' which are opposed to each other with a width slightly narrower than the head a' of the clip body 1, and further have a leaf spring 7 fitted in a curved shape in the inner right half of the clip body 1, and whose both ends are provided inside the clip body 1.
This is because it was locked in place.

[Effect]

When the clip body 1 is pinched with fingertips, the clip body 1 deforms and the clamping pieces 4,
5 moves left and right, and has an arc-shaped recessed tip 4b, 5b.
The gap between them widens. In this state, when the button electrode a is inserted into the head part a' of the button electrode a attached to the body and the fingertip is released, the clip body 1 moves as shown in FIG. The neck of the head a' with the recessed tips 4b and 5b of the tips of the clamping pieces 4 and 5.
The clip body 1 is securely connected to the button electrode by holding the button a''.Also, the clip body 1 can be removed by operating the clip body 1 with the fingertips in the same manner as described above.

〔Example〕

In the figure, reference numeral 1 denotes a clip body having a substantially circular frame shape and made of soft synthetic resin. Reference numerals 2 and 3 refer to thick portions disposed opposite to each other on the left and right inner sides of the clip body 1;
Reference numerals 4 and 5 indicate clamping pieces made of conductive material, each of which has bent bases 4a and 5a embedded in and fixed in the thick parts 2 and 3, and a conductive wire 6 is connected to one of the bent bases 5a. . Then, the arc-shaped recessed tips 4b and 5b provided on each clamping piece 4 and 5 are opposed to each other with a width slightly narrower than the head a' of the button electrode a. Furthermore, a leaf spring 7 is fitted into the right inner half of the clip body 1 in a curved manner, and both ends of the leaf spring 7 are engaged with protrusions 8 and 8' provided inside the clip body 1. In the figure, reference numeral 9 denotes an anti-slip protrusion protruding from the outside of the clip body 1, and 10 denotes a protective tube for the conducting wire 6, which is formed integrally with the clip body 1.

[Effect of idea]

The clip electrode of the present invention has a much simpler structure than conventional ones, so it can be mass-produced and supplied at a low cost, and is small and lightweight, making it ideal for infants.
