Patient simulator

Abstract

The invention relates to a patient simulator that is characterized by comprising an electromyographic signal generation module (1), a stimulation sheet (2), a stimulation loop electrode wire (3), a grounding electrode wire (4) and a simulation subcutaneous recording electrode wire (5), and the stimulation sheet (2), the stimulation loop electrode wire (3), the grounding electrode wire (4) and thesimulation subcutaneous recording electrode wire (5) are electrically connected with the electromyographic signal generation module (1). When the nerve monitoring system breaks down, the patient simulator can be used for rapidly and effectively eliminating the system faults, and after the system faults are rapidly eliminated, the nerve monitoring system continues to work to help a surgeon locate and identify dangerous nerves in a surgical operation area, so that the nerves are protected from being damaged in the operation process. When the nerve monitoring system needs to be demonstrated outside an operation, the patient simulator is used, interaction with a patient is not needed, operation is easy and convenient, and the patient simulator is a convenient tool for testing all functions ofthe nerve monitoring system.

Description

technical field [0001] The invention relates to a medical testing product, in particular to a nerve monitoring technology, in particular to a patient simulator used in the nerve monitoring and testing process. Background technique [0002] In surgery, a neuromonitoring system is often used to monitor nerve electromyographic signals and provide assistance for surgery. Surgeons can touch sites on a patient with stimulating electrodes to deliver a stimulating current to the site on the patient's body, thereby stimulating nerve activity and causing a muscle response. After the recording electrode receives the EMG signal, it transmits it to the nerve monitoring host, and the host records the EMG after processing and gives an alarm in real time. Helps surgeons locate and identify nerves at risk in the surgical field, thereby protecting nerves from damage during surgery. [0003] In the normal demonstration process of the nerve monitoring system, it is necessary to establish a ne...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that there is no quick and effective method to eliminate the system failure when the existing nerve monitoring system breaks down. After the failure is solved, the nerve monitoring system continues to work, and the operation is cumbersome when the nerve monitoring system is demonstrated. , to design a quick and effective way to troubleshoot the nerve monitoring system, and at the same time provide a convenient connection method during the demonstration of the nerve monitoring system, a simple and feasible patient simulator
