Monitor for monitoring diaphragm motion conditions

Abstract

Disclosed is a monitor for monitoring the movement of the diaphragm, comprising: an ultrasound probe (100), which is fixed on the surface of the user's body for transmitting ultrasonic waves to the user and scanning the user's diaphragmatic movement; an ultrasonic detection module (120) connected to the ultrasound probe (100) for controlling the ultrasound probe (100) to transmit ultrasonic waves to the user, and to receive the echo signals acquired by the ultrasound probe (100); a diaphragm movement state generation module (121) for generating curve information or image information characterizing the diaphragm movement state according to the echo signals received by the ultrasonic detection module (120); and a first display module (122) for displaying the curve information or image information generated by the diaphragm movement state generation module (121). The monitor can obtain the real-time movement condition of the diaphragm and transform it into a movement image or movement curve so as to accurately and safely detect the degree of muscle relaxation.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a monitor for monitoring the movement of the diaphragm Background technique [0002] 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. [0003] In the prior art, th...

Problems solved by technology

[0004] 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

[0005] 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 applying muscle relaxants is to relax the respiratory muscles to facilitate tracheal intubation and During the 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

[0006] 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 depressants, and the measurement results are inaccurate

[0007] 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
