Description

A monitor for monitoring the movement of the diaphragm

technical field

The invention relates to the field of medical devices, in particular to a monitor for monitoring the movement of the diaphragm

Background technique

Due to factors such as the large dose range of muscle relaxants, large individual differences, and inaccurate effect failure, routine monitoring of the degree of muscle relaxation can guide the rational application of muscle relaxants during anesthesia, and can ensure the muscle relaxation requirements of different stages of anesthesia. In addition, maintaining adequate recovery of neuromuscular function after surgery is a necessary condition to ensure that patients can maintain adequate ventilation and maintain airway patency, and postoperative residual muscle relaxation is the most common cause of postoperative respiratory complications. Relaxation can reduce the incidence of postoperative residual muscle relaxation and avoid postoperative respiratory complications.

In the prior art, the clinical status of muscle relaxation monitoring is as follows:

The anesthesiologist directly manually measures the muscle strength of voluntary muscles, such as raising the head, grip strength, opening eyes, tongue out, etc. Disadvantage: The patient needs to stay awake and cooperate.

The muscle relaxation monitor monitors the mechanical effect/electrical effect/acceleration effect of muscle contraction of non-respiratory muscles (such as adductor hallucis, orbicularis oculi, etc.). Disadvantages: the purpose of using muscle relaxants is to relax the respiratory muscles to facilitate tracheal intubation and During operation, different muscle groups have different sensitivity to muscle relaxants and recovery speed, so the evaluation of non-respiratory muscles cannot directly reflect the muscle relaxation of respiratory muscles.

In addition, muscle relaxation can also be monitored by measuring tidal volume, vital capacity, etc., which are affected by many factors, such as the depth of general anesthesia and the effect of central nervous system inhibitors, and the measurement results are inaccurate.

In the prior art, muscle relaxation can also be detected by observing the movement of the diaphragm under X-rays. The disadvantage is that X-rays have radiation damage to the human body and cannot be monitored for a long time.

Therefore, it is necessary to provide a technical solution that can monitor the degree of muscle relaxation in real time, accurately and safely.
