technical field

The utility model belongs to the field of medical devices, in particular to a muscle relaxation monitor.

Background technique

The muscle relaxation monitor is suitable for the monitoring of surgical anesthesia and ICU patients, continuous real-time monitoring of changes in the degree of muscle relaxation, objectively reflecting the ebb and flow process of muscle relaxation, correctly guiding the application of muscle relaxants and conducting research on the pharmacodynamics of muscle relaxants , In the process of surgical anesthesia, it is an instrument to observe the effect of muscle relaxant by stimulating the peripheral nerve to cause the patient's muscle twitching. There are large individual differences in muscle relaxants, and different muscle groups in the body have different sensitivities to muscle relaxants. Monitoring muscle tension can guide the rational application of muscle relaxants during anesthesia, and can ensure muscle relaxation requirements at different stages of anesthesia. It is beneficial to grasp the timing of intubation and extubation, reduce the incidence of residual effect of postoperative muscle relaxants, and ensure patient safety.

In the case of complete neuromuscular function, when the peripheral motor nerves are stimulated with electricity to achieve a certain stimulation intensity, the muscle will contract to generate a certain muscle force. The force depends on the number of muscle fibers involved in the contraction. If the stimulation intensity exceeds the threshold, all the muscle fibers innervated by the nerve will contract, and the muscle will produce the maximum contraction force. The largest contraction response, super stimulation will produce pain, the patient feels no pain during anesthesia, but can feel pain during the recovery period.
