Loop type anesthesia ventilation system

Abstract

The invention relates to the field of medical equipment, and particularly relates to a loop type anesthesia ventilation system. The loop type anesthesia ventilation system comprises an anesthesia machine, a breathing loop for preventing repeated breathing, a breathing mask and a fixing device, wherein the anesthesia machine, the breathing loop for preventing repeated breathing and the breathing mask are connected through corresponding interfaces, and the breathing mask is fixed through the fixing device. The loop type anesthesia ventilation system has the advantages that repeated inhalation and exhalation of gas during autonomous respiration of a patient are effectively decreased through the breathing loop for preventing repeated breathing, the volume of an invalid cavity is decreased, andthe sedative or anesthetic patient performs autonomous respiration through a loop at low fresh air flow rate, especially when the patient inhales anesthetic. The stress of the contact position of thepatient, the breathing mask and the fixing device is dispersed and stable, so that the sedative or anesthetic patient can conveniently achieve continuous and stable autonomous respiration through theloop type anesthesia ventilation system.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a loop-type anesthesia ventilation system. Background technique [0002] In clinical anesthesia, patients who have received sedation or anesthesia, especially those who need to maintain sedation or anesthesia for a long time, because their respiratory function is inhibited to a certain extent, pure inhalation of air cannot meet the oxygen demand of such patients Or there is a risk of potential hypoxia, which often requires the inhalation of a higher concentration of oxygen; when the patient is sedated or anesthetized with inhaled anesthetics, due to the requirements for the effect of sedation or anesthesia and the consideration of environmental pollution, it is necessary to have an operating room The environment is relatively isolated breathing pathway; in addition, due to the requirements of disinfection and draping, the patient's face needs to be covered, and the patient needs ...

AI Technical Summary

Problems solved by technology

[0006] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a loop anesthesia ventilation system, which is used to solve the problem that in the existing clinical anesthesia technology, patients who are sedated or anesthetized maintain spontaneous breathing through the loop anesthesia ventilation system. When low fresh gas flow ventilation, CO 2 Easy to accumulate, poor stability and inconvenient fixing method of breathing mask
