Description

Monitor for monitoring diaphragmatic motion

[Technical Field]

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

【Background technique】

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

The clinical status of general muscle relaxation monitoring is as follows:

The anesthesiologist directly measures the muscle strength of the voluntary muscle, such as raising the head, gripping force, blinking the eye, stretching the tongue, etc. Disadvantages: the patient needs to stay awake.

The muscle relaxation monitor monitors the mechanical effects/electrical effects/acceleration effects of muscle contraction of non-respiratory muscles (such as the adductor muscles, orbicularis oculi muscles). Disadvantages: The purpose of applying muscle relaxants is to relax the respiratory muscles for tracheal intubation and Intraoperative operation, different muscle groups are sensitive to muscle relaxants and recovery speed, so the evaluation of non-respiratory muscles can not directly reflect the respiratory muscles.

In addition, muscle relaxants can be monitored by measuring tidal volume, vital capacity, etc., which are affected by various factors, such as general anesthesia and central nervous system inhibitory drugs, and the measurement results are not accurate.

Generally, the muscle relaxation can be detected by observing the transverse movement under the X-ray. The disadvantage is that the X-ray has radiation damage to the human body and cannot be monitored for a long time.

[Summary of the Invention]

Based on this, it is necessary to provide a monitor that monitors the movement of the diaphragm muscles to safely monitor the degree of muscle relaxation.

A monitor for monitoring diaphragmatic motion, including:

The ultrasonic probe is fixed on the body surface of the user for transmitting ultrasonic waves to the user and scanning the diaphragm movement;

An ultrasonic detecting module, coupled to the ultrasonic probe, for controlling the ultrasonic probe to transmit ultrasonic waves to a user, and receiving an echo signal obtained by the ultrasonic probe;

a diaphragm movement state generating module, configured to generate curve information or image information indicating a diaphragm muscle motion state according to the echo signal received by the ultrasound detecting module;

The first display module is configured to display curve information or image information generated by the diaphragm movement state generating module.

The above monitor for monitoring the movement of the diaphragm muscle obtains the movement state of the diaphragm of the user in real time through an ultrasonic probe fixed on the surface of the user, and converts it into curve or image information, so as to provide the monitor with accurate information on the diaphragm movement, which can be accurately and safely monitored. The degree of muscle relaxation.
