In research experiments on cardiac electrophysiology and the like, electrocardiogram data of experimental animals is an important observation index.
The electrocardiogram data is obtained by matching the electrocardiograph with the lead electrodes, and the lead electrodes are connected with the electrocardiograph by using the connecting device to obtain the electrocardiogram data. The lead electrode designed for human body is too large in volume, can not be fixed on four limbs of experimental animal and put the chest lead on the corresponding part of animal heart, and is easy to contact other parts of animal body or nearby objects to generate interference, so that the electrocardiogram of experimental animal can not be directly measured.
Some lead electrodes adopt small-sized metal clamps, although the lead electrodes can be fixed on limbs of animals, metal needles or similar sharp objects are needed to be used for puncturing the skin of the four limbs of the anesthetized animals, and then the electrode clamps and the metal needles are connected and fixed, so that the process is complicated, the electrodes are easy to touch surrounding objects during operation to cause interference, and laboratory personnel are also easy to be affected by the sharp objects to be accidentally punctured.

Lead electrodes, metal conductors for obtaining electrocardiogram data.
As described in the background art, most of the electrocardiogram lead electrode clamps used in experimental animals can only measure the data of the four limbs of the animal, and the chest lead data contains abundant information reflecting the heart state. For example, in the case of a rat, the chest area of the rat is small, and chest lead data is difficult to measure, while the measurement is performed subcutaneously by inserting an electrode needle into the chest of the rat in the prior art. If the insertion depth is deep in the measurement process, the tissue damage and even the heart damage can be caused, and if the insertion depth is shallow, the electrode needle fixation can be unstable, so that the electrocardiosignal interference is large.
Therefore, the following embodiments provide a lead electrode connecting device for electrocardiogram of experimental animals, which utilizes an electrode clip with protrusions to clamp on the chest or four limbs of a rat, thereby avoiding tissue damage caused by traditional sharp objects, the electrode clip is connected with a groove through a lead, an expansion space is provided for a joint of an electrocardiogram machine by utilizing an opening on the groove, and the electrode clip is prevented from being pulled and disconnected with the electrocardiogram machine during experimental operation.
