Anesthesia respirator and structure thereof for sealing soda lime tank

Abstract

The invention provides a structure for sealing a soda lime tank, which is used on a respiration loop main body of an anesthesia respirator, and comprises an upper tray, a seal ring and a filter mesh, wherein the upper tray is fixed on the respiration loop main body of the anesthesia respirator; the upper tray comprises a first vent hole which is communicated with a vent hole of the respiration loop main body; the seal ring is arranged between the upper tray and a port of a tank body of the soda lime tank; the seal ring comprises a second vent hole penetrating through the upper end surface and the lower end surface; the first vent hole is communicated with the second vent hole; the lower end surface of the seal ring is a plane; and the filter mesh is arranged between the upper tray and the seal ring. According to the structure for sealing the soda lime tank, the effect of sealing the soda lime tank is good; simultaneously, according to the structure for sealing the soda lime tank, the assembly and the disassembly are convenient, the assembly working time is effectively saved, and the effect of improving the working efficiency can be achieved.

Description

technical field [0001] The invention relates to the field of medical devices, more specifically, to an anesthesia ventilator and a sealing structure of a soda lime tank thereof. Background technique [0002] At present, the absorption of carbon dioxide in the breathing circuit of the anesthesia ventilator adopts the method of soda lime absorption, and the soda lime is packed in the soda lime tank, so the soda lime tank is a main part of the breathing circuit of the anesthesia machine, and the typical anesthesia ventilator on the market now Breathing circuit structure such as figure 1 As shown, it mainly includes the main body of the breathing circuit, the soda lime tank 30, the clamping mechanism of the soda lime tank, the alignment mechanism of the soda lime tank, the sealing structure of the soda lime tank (such as figure 2 Shown) and other parts, carbon dioxide gas is discharged into the soda lime tank from the vent hole of the breathing circuit. Because the soda lime ...
