Carbon dioxide absorber

Abstract

The invention relates to the technical field of carbon dioxide absorption equipment, and particularly discloses a carbon dioxide absorber. The carbon dioxide absorber comprises a shell, and a gas inlet pipeline, a gas outlet pipeline and an absorbent sieve plate which are mounted in the shell, wherein the shell is hollow, and a gas inlet and a gas outlet which communicate with the outside are formed in the upper end of the shell; the absorbent sieve plate is horizontally installed in the shell and divides the interior of the shell into an absorption area and a dust collection area; the upper end of the gas inlet pipeline hermetically communicates with the gas inlet, the lower end of the gas inlet pipeline is provided with a gas outlet hole, and the gas inlet communicates with the absorption area through the gas outlet hole; and the upper end of the gas outlet pipeline is connected with the gas outlet, a gas inlet hole is formed in the gas outlet pipeline close to the gas outlet, and the gas outlet communicates with the absorption area through the gas inlet hole. The carbon dioxide absorber disclosed by the invention has a simple structural design, so that the carbon dioxide absorber has relatively low product cost, one-person and one-tank distribution and use are further realized, the hidden danger of cross infection is thoroughly avoided, and the carbon dioxide absorber is easy to popularize clinically.

Description

technical field [0001] The invention relates to the technical field of carbon dioxide absorbing equipment, in particular to a carbon dioxide absorber. Background technique [0002] During the mechanical ventilation of the anesthesia machine, the closed loop mode is adopted. The exhaled gas (mixed gas containing carbon dioxide, mainly oxygen, or anesthetic gas) in the breathing circuit of the anesthesia machine absorbs carbon dioxide gas through the carbon dioxide absorption tank and then enters the breathing circuit again for use. . The working principle of the carbon dioxide absorption tank is that the carbon dioxide absorbent contained in it reacts chemically with carbon dioxide, thereby realizing the absorption of carbon dioxide. When using the carbon dioxide absorption tank to absorb the exhaled gas in the breathing circuit of the anesthesia machine, the exhaled gas in the breathing circuit of the anesthesia machine enters the carbon dioxide absorption tank through the ...

AI Technical Summary

Problems solved by technology

Different anesthesia machines have complex tank structures. In order to ensure the tightness of product assembly, the product structure is complex and the tank cost is high

At the same time, each type of original tank has a large cross-sectional area. In order to ensure the carbon dioxide absorption effect, the weight of the carbon dioxide particles that need to be loaded is relatively large. If one person uses one tank, the waste will be large and the cost will be extremely high.

This is contrary to the current reduction of clinical medical expenses. It is difficult to promote the one-time use of one person and one can in the clinic, and it is difficult to completely eliminate the hidden danger of cross-infection. Therefore, there is an urgent need for low-cost disposable carbon dioxide absorption devices in clinical practice.
