Embodiment Construction

[0010] As shown in the drawings, the present invention includes two clamping members 2, 2' with a pair of inwardly protruding fins 7, 7' in the middle. On the rotating shaft 4 of the two pairs of wings 7, 7', one end of the clamp spring 3 is fixed on the inner surface of one clamping member 2, and the other end of the clamp spring 3 is fixed on the inner surface of the other clamping member 2, so as to realize a pair of clamping The opening and closing movement of the components 2 , 2 ′ around the clamp shaft 4 . An electrode 1 connected with a wire 6 is installed on the inner surface of the upper end of one clamping member 2 , and a non-conductive buffer pad is installed on the inner surface of the upper end of the other clamping member 2 ′ opposite to the electrode 1 .

[0011] The electrode 1 is a conductor with a raised surface, which can be a metal mesh or a solid metal or a hollow metal. The cross-section is square or rectangular or circular or oval or other cross-secti...

Abstract

The invention discloses a reference electrode clip for measuring biological resistance, impedance and potential. It consists of two clamping members with a pair of fins protruding inward in the middle. The fin holes are connected by a clamp shaft. The clamp spring is sleeved on the rotation shaft of the two pairs of fins. On the inner side, the other end of the clip spring is fixed on the inner side of the other clamping member to realize the opening and closing movement of the pair of clamping members around the clamping shaft. On the inner side of the upper end of a clamping member, an electrode connected with a wire is provided. Or a non-conductive buffer pad is installed on the inner surface of the upper end of the other clamping member at the position opposite to the electrode. When in use, connect the reference electrode clip to the measurement circuit, then open the electrode clip, and fix the electrode on the surface of the human body by the clamp force of the clip, so that the electrode is in full contact with the surface of the human body, and can be used together with the measuring electrode for measurement. It is also very convenient and quick to take off the electrodes, which will not cause discomfort to the human body and is suitable for repeated use.

Description

technical field [0001] The invention relates to a medical device, in particular to a reference electrode clip for measuring biological resistance, impedance and potential. Background technique [0002] The utility model patent 93227306.8 proposes a contact electrode of an electronic therapy device. The electrode is fixed on the surface of the human body by glue. The human body brings discomfort. The utility model patent 95246280.X proposes an electrode of an electronic diagnosis and treatment device with a sheath, which also has the above-mentioned problems. Contents of the invention [0003] The object of the present invention is to provide a reference electrode clip for bio-resistance, impedance and potential measurement, which is used to inject measurement signals into the human body and form a loop together with the measurement electrodes. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is as follows: [0005] It ...
