Electrode substrate and monitoring electrode

Abstract

The invention relates to the field of medical instruments, in particular to an electrode substrate and a monitoring electrode. The electrode substrate comprises a substrate body, wherein a blood accommodating space is formed in the substrate body, and the blood accommodating space can suck blood of a monitored part during bleeding. The monitoring electrode comprises electrode plates, electrode guide wires and the electrode substrate, wherein the electrode plates are arranged on the electrode substrate, one end of each electrode guide wire is connected with the corresponding electrode plate, and the other end of each electrode guide wire is used for being connected with monitoring equipment. The blood accommodating space is formed in the substrate body, exudative blood can be sucked throughthe blood accommodating space under the condition that bleeding exists in human tissue or bleeding exists due to vascular rupture, then whether bleeding exists among tissues or not can be judged in time according to whether blood is sucked in the blood accommodating space or not; then corresponding operations can be performed in time, and the probability of complications and a secondary surgery is reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an electrode base and a monitoring electrode. Background technique [0002] In some operations involving the central nervous system, such as brain tumor resection, EEG monitoring, spinal cord tumor resection, and scoliosis correction, there is a risk of neurological damage. Once damaged, it will cause serious complications to the patient. The neurophysiological monitoring can enable the operator to know whether the ongoing operation has caused nerve damage; it can detect and correct the damage caused by the operation in time to avoid permanent damage. Therefore, effective intraoperative neuromonitoring is necessary. [0003] Strip electrodes are widely used in neurophysiological monitoring. Specifically, in the process of intraoperative use, such as spinal surgery, the spine and the inner dura mater of the spine need to be opened first, and the monitoring electrodes are pushed in...

AI Technical Summary

Problems solved by technology

[0004] Because the electrodes need to be pushed into the tissue space during use, they put pressure on the surrounding tissue and may cause bleeding

If this type of bleeding cannot be detected in time during the operation, on the one hand, it will affect the monitoring. On the other hand, the bleeding will usually cause serious complications to the patient. If necessary, a second surgery is required to correct it.
