Lead electrode connecting device for experimental animal electrocardiogram

Abstract

The invention relates to a lead electrode connecting device for an experimental animal electrocardiogram. The lead electrode connecting device comprises an electrode clamp and a groove which are connected to the two ends of a wire. The electrode clamp comprises an upper clamp body and a lower clamp body which are rotationally connected, and the head ends of the two clamp bodies are attached to each other to form a clamp opening with a protrusion. The electrode clamps comprise limb lead electrode clamps and chest lead electrode clamps, upper clamp bodies and lower clamp bodies of the chest lead electrode clamps are made of conductor materials, the upper clamp bodies of the limb lead electrode clamps are made of conductor materials, and the lower clamp bodies of the limb lead electrode clamps are made of insulating materials; the groove is a cylindrical conductor, the rear end of the groove is connected with the wire, and an insertion hole is formed in the front end of the groove and used for containing a lead wire connector of the electrocardiograph. The electrode clamp with the protrusions is used for clamping the chest or four limbs of a rat, tissue damage caused by traditional sharp objects is avoided, the electrode clamp is connected with the groove through the wire, an expansion space is provided for a connector of an electrocardiograph through the opening in the groove, and the electrode clamp is prevented from being pulled to be disconnected from the electrocardiograph in the experiment operation period.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a lead electrode connection device for an experimental animal electrocardiogram. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Electrocardiogram is an important physiological index, which can reflect the basic state and pathological changes of the heart, and is an important basis for judging heart function. In research experiments related to cardiac electrophysiology, the electrocardiogram data of experimental animals is an important observation index. [0004] The ECG data is obtained by using the electrocardiograph together with the lead electrodes, and the lead electrodes need to be connected with the electrocardiograph by a connection device to obtain the electrocardiogram data. The lead electrode designed for the human b...

AI Technical Summary

Problems solved by technology

However, the chest area of ​​rats is small, and it is difficult to measure the chest leads, while the existing technology uses electrode needles inserted into the rat chest subcutaneously for measurement

If the insertion is deep during the measurement process, it may cause tissue damage, or even damage the heart; if the insertion is shallow, it may lead to unstable fixation of the electrode needle, resulting in greater interference of the ECG signal
