Anesthesia system compatible with ascending and descending bellows breathing circuits

Abstract

The invention relates to an anesthetization system integrating an ascending type bellow respiration loop and a descending type bellow respiration loop. The anesthetization system comprises an anesthetization main machine and the ascending type bellow respiration loop and the descending type bellow respiration loop which are detachably mounted on the main anesthetization machine respectively. The ascending type bellow respiration loop comprises an ascending bellow and a first bellow main machine connected with the ascending bellow, and the first bellow main machine comprises a first joint assembly which achieves air channel communication with the inner side and the outer side of an ascending air bag. The descending type bellow respiration loop comprises a descending bellow and a second bellow main machine connected with the descending bellow; the second bellow main machine also comprises a first joint assembly which achieves air channel communication with the inner side and the outer side of a descending air bag. The anesthetization main machine comprises a second joint assembly, and the first bellow main machine and the first joint assembly of the second bellow main machine are correspondingly matched with the second joint assembly, so that communication of an air channel between the ascending type bellow respiration loop and the anesthetization main machine as well as an air channel between the descending type bellow respiration loop and the anesthetization main machine is achieved. The anesthetization system can meet requirements of different groups of customers.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an anesthesia system compatible with ascending and descending bellows breathing circuits. Background technique [0002] In the anesthesia machine system scheme, the breathing circuit is the closest to the patient. Its main function and role are: to provide a closed breathing channel for mechanical ventilation or manual ventilation, so that the CO2 gas in the patient's exhaled gas is absorbed by soda lime and exhaled The anesthetic gas in the gas can be repeatedly inhaled by the patient; at the same time, the breathing circuit also realizes the monitoring of tidal volume, airway pressure and oxygen concentration. [0003] In the global market, different countries or regions have different preferences for bellows. Some countries and regions are accustomed to using the breathing circuit of ascending bellows, while some countries and regions are accustomed to using the breathing circ...

Problems solved by technology

[0007] And the user who chooses the descending bellows breathing circuit thinks: 1) If the machine of the ascending bellows breathing circuit leaks, it is necessary to press the quick oxygenation device to fill up the collapsed folding bag until it rises to the top of the bellows; As a result, the concentration of anesthetic gas in the breathing circuit is rapidly diluted by the rapidly inflated oxygen, that is, the concentration of anesthesia drops significantly, which affects the effect of anesthesia. It takes a long time for the system to reach the previous anesthesia concentration
