おり、正確に特定することが因難である。(2) Prior art and problems Recently, with the development of emergency patient treatment rooms and central control rooms, it has become important to continuously and accurately directly measure substances in the body, such as blood, gases, and other specific components. is increasing. In response to this, a method has been considered in which wire-type electrodes with thin conductive wires are inserted directly into blood vessels and tissues of a living body, and substances in the living body are continuously detected through electrode reactions. We have already proposed an electrode (Utility Application No. 54-153522). However, when inserting an electrode attached to the tip of a thin conductive wire directly into a living body, the position and depth of the sensing part at the tip are determined by the experimenter's sense, and it is difficult to identify it accurately. be.

達成することができる。(4) Structure of the invention The above-mentioned object of the invention is to provide a wire-type electrode for biological use that has a sensing part at the tip of the conducting wire, and to provide insulation along the length of the conducting wire on the insulating coating of the part of the conducting wire near the sensing part. This can be achieved with a biomedical wire type electrode, which is characterized by a raised scale on the coating.
絶縁被覆上の目盛は色相が異ることが便宜であ

ことを防止する効果を有する。 It is convenient for the scales on the insulation coating to have different hues. For example, if the scale interval is 1 mm and the hue is different every 5 mm, the scale can be easily read. Also, the scale is somewhat raised on the insulation coating.
When inserted into a living body, the convex portion stimulates the muscles and causes them to contract, which has the effect of preventing the sensor from being pulled out of the living body.

A detection part 2 is provided at the tip of the conducting wire 1, and the conducting wire 1 is covered with an insulating coating 3. A scale 4 is provided on a portion of the conductive wire near the detection section 2. Although the figure shows a continuous linear scale 4 surrounding the periphery of the insulating coating 3, this may be a continuous point.

い。 The insulating coating 3 is made of epoxy resin, polyvinyl formal, polyamide, polyurethane, or the like. The film thickness varies depending on the diameter of the conducting wire 1, the degree of insulation, and the purpose of use, but is usually about 5 to 200 μm. The raised scale 4 may be formed by coating the coating resin with a different dye or pigment, for example.

抜け出ることを防止する。(6) Effects of the invention The biomedical wire type electrode of the present invention allows the distance from the skin to the detection part to be measured visually using the scale provided on the insulation coating of the conductor near the detection part, so the depth and position of the detection part can be measured visually. Not only can the sensor be accurately identified, but also the convex portion of the scale prevents the sensor from slipping out of the living body.
