Disposable anesthetic gas adsorber

Abstract

The invention relates to a disposable anesthetic gas adsorber, which comprises an upper cover (1), a lower seat (2), a gas inlet packaging cover (3) and a gas outlet packaging cover (4), wherein the upper cover and the lower seat are connected through a clamping structure, the joint surface of the upper cover and the lower seat is sealed through an outer sealing ring (6), a spacer ring (9) is clamped on the outer side of an air outlet pipe (5) and in the lower seat, the lower seat forms an inner side active carbon mounting area (11) and an outer side active carbon mounting area (12) through the spacer ring, the upper end of the air outlet pipe is sleeved with an elastic filter plate (13), the elastic filter plate (13) is provided with air outlet holes (14), air distribution heads (15) areclamped on the spacer ring (9), the outer side edge of the clamping groove of the air distribution head (15) and the spacer ring (9) are sealed through an inner sealing ring (16), air inlet holes (17)are formed in the outer sides of the air distribution heads (15), and a plurality of pressing plates (18) for pressing the air distribution heads (2) are arranged on the inner side of the upper cover(1). The disposable anesthetic gas adsorber is simple in structure and convenient to install.

Description

technical field [0001] The invention relates to a medical device accessory, in particular to a gas purifier for an anesthesia machine, in particular to a disposable anesthesia gas adsorber. Background technique [0002] As we all know, most of the anesthesia gas generated during the use of the anesthesia machine enters the mouth of the anesthetized object, but some gas will still escape during the generation of the anesthesia gas, which must be collected and purified before being discharged, otherwise the discharged gas will be harmful to the medical staff. To cause injury to personnel, the usual purification method is to use activated carbon for adsorption. Through the adsorption of activated carbon, the anesthetic gas is deactivated and converted into oxygen and carbon dioxide to achieve safe discharge. The absorption rate of the anesthetic in the anesthesia tail gas can reach more than 99∅ by using the disposable anesthetic gas adsorber, so it is widely used. [0003] As...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to design a disposable anesthesia gas adsorber that is not only convenient to connect but also can properly adjust the volume of the activated carbon installation cavity for the problems of inconvenient installation and difficulty in adapting to the volume change of activated carbon in the existing anesthetic gas adsorber.
