JPH1066682A - Medical tape electrode structure in which mounting of electrode cord is improved - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reduce the peeling of a tape electrode by body movement seen in the case of connecting the tape electrode to an electrode cord by arranging snap terminals in one column with fixed intervals on the tape electrode. SOLUTION: In this medical tape electrode structure for which the mounting of the electrode cord is improved, snap male terminals 4 are disposed in one column with the fixed intervals on the existing tape electrode 3 and a snap female terminal 2 is used at the tip of the electrode cord 1 further. Since the follow-up ability of the electrode cord to the body movement is excellent even at the time of being cut in an optional length, the peeling of the tape electrode is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical tape electrode structure having an improved mounting of an electrode cord, and more particularly to an electrode structure using a medical disposable (disposable) tape electrode.

[0002]

2. Description of the Related Art The technology relating to the conventional medical disposable tape electrode is a known fact and has been commercialized by medical device manufacturers. When an existing disposable tape electrode (hereinafter, abbreviated as a tape electrode) is connected to an electrode cord, a clip is used to fix the tape electrode and the electrode cord.

FIG. 4 is an external view showing an example of using a conventional medical disposable tape electrode. In FIG. 4, the clip 6 at the tip of the electrode cord 1 is used to connect to the aluminum portion 7 of the tape electrode 3, and is further attached to the living body with a clip fixing tape 8.

[0004]

The conventional problem is that the clip at the tip of the electrode cord moves due to body movement, and as a result, the tape electrode itself comes off.

[0005] The reason for this is that the clip is made of a harder material than the living body and has poor ability to follow the body movement, so that the space between the clip fixed with tape and the contact portion of the living body expands.
That is, the movement of the clip cannot be suppressed.

[0006]

According to the medical tape electrode structure of the present invention, in which the mounting of the electrode cord is improved, the first snap terminals (see FIG. 1A) are arranged on the existing tape electrode (3 in FIG. 1A) at regular intervals in a line. 1) 4) is arranged, and the second snap terminal (2 in FIG. 1) of the electrode cord is inserted and connected via the first snap terminal.

[0007]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 shows a first embodiment of the medical tape electrode structure of the present invention.
(A) is a plan view, and (b) is an AA
It is sectional drawing. In the figure, an existing tape electrode 3 is stuck on the skin 5 of a living body. The tape electrode 3 is an aluminum electrode, but may be another conductive electrode.

At the center of the tape electrode 3, fixed metal male snap terminals 4 are fixed in a line at regular intervals, preferably at intervals of 4 cm. The spacing between the snap male terminals is such that the average chest circumference of an adult male is about 85 cm, and half the circumference of the chest circumference can be divided into approximately 10 equal parts. Snap male terminal 4
Has an electrode protrusion 4a extending vertically from the electrode bottom fixed to the tape electrode 3.

On the other hand, a snap female terminal 2 is fixed to the tip of the electrode cord 1 connected to the tape electrode 3.
The snap female terminal 2 is an electrode projection 4 of the snap male terminal 4.
a is inserted and connected.

As shown in FIG. 2, the snap female terminal 2 is
An insulator housing 20 and an electrode portion 21 fixed in the housing and connected to the code electrode 1 are provided. The electrode portion 21 has a spring-shaped connection portion with the electrode protrusion 4a of the snap male terminal 4. I have. Therefore, the snap female terminal 2 is firmly connected to the snap male terminal 4. However, the snap female terminal 2 is rotatable about the electrode protrusion 4a with respect to the snap male terminal 4.

The electrode portion 21 shown in FIG. 2 does not necessarily need to be connected to the snap male terminal 4 by a spring property.
For example, the electrode portion 21 may be a cylindrical electrode portion, and the outer diameter of the electrode protrusion 4a inserted therein may be substantially equal to the inner diameter.

The electrode portion 21 of the snap female terminal 2 may be formed as a cylindrical electrode, and the electrode projection 4a of the snap male terminal 4 may be connected in the electrode portion 21 with a spring property.

As described above, in the medical tape electrode structure of FIG. 1, the connection strength between the tape electrode 3 and the code electrode 1 is maintained, and the code electrode 1 may come off from the tape electrode 3 due to the movement of the living body. Is prevented. Further, since the snap male terminals 4 are fixed at regular intervals in the length direction of the tape electrode 3, the tape electrode 3 can be cut at an arbitrary position.

FIG. 3 shows a second embodiment of the medical tape electrode structure of the present invention.
(A) is a plan view, (b) is BB
It is sectional drawing. In the present embodiment, the snap female terminal 2 is fixed to the tape electrode 3, and the snap male terminal 4 is connected to the code electrode 1. That is, the relationship between the male and female snap terminals is opposite to that of the first embodiment.

The second embodiment is superior to the structure shown in FIG. 1 in that the snap terminal on the living body side is a female type, so that the projection does not interfere.

[0017]

A first effect of the present invention is that peeling of the tape electrode due to body movement can be reduced. The reason is that, by connecting the tape electrode and the electrode cord with a snap terminal, the followability of the electrode cord to body movement is improved.

A second advantage of the present invention is that it can be cut to an arbitrary length and used as a tape electrode with a snap terminal. The reason is that the snap terminals are arranged in a line at regular intervals on the tape electrode.
