Suction type anesthesia machine for general anesthesia

Abstract

The invention relates to an anaesthesia machine technology, in particular to an inhalation type anaesthesia machine for general anesthesia, which is used for solving the problems that water vapor in a mask is gathered into water drops to drip and then enters the trachea of a patient along with breathing to cause discomfort, and the anaesthesia effect is affected due to the fact that more water vapor easily breeds bacteria and the exhaust speed of waste gas is low at the position of a mask connecting port. Comprising an anaesthesia machine body, an air inlet pipe, an exhaust pipe and a mask. A dehumidification driving gear is driven by a driving shaft to rotate, the dehumidification driving gear is matched with a driven gear, so that water vapor on the inner wall of a mask is cleaned through reciprocating swing of a telescopic sleeve connected with a dehumidification sponge, and a bacteriostatic driven gear is driven by the driving shaft to rotate; the cleaning sponge on the rotating frame can absorb water vapor at a connector of the mask, bacteria and dust are prevented from being bred and attached to the connector, the reciprocating lead screw is driven by the driving shaft to rotate, and waste gas exhaled by a patient in the mask is rapidly transmitted into an exhaust pipe through the telescopic hose.

Description

technical field [0001] The invention relates to anesthesia machine technology, in particular to an inhalation anesthesia machine for general anesthesia. Background technique [0002] The anesthesia machine sends the anesthetic into the alveoli of the patient through a mechanical circuit, forming a partial pressure of the anesthetic gas, which diffuses into the blood, and directly inhibits the central nervous system, thereby producing the effect of general anesthesia. The anesthesia machine is a semi-open anesthesia device. [0003] In the prior art, when the mask rolls on the patient's mouth and nose to guide the atomized anesthetic, the exhaust gas exhaled by the patient carries a certain amount of heat. In the case of condensation, the water vapor in the exhaust gas condenses into small water droplets and adheres to the inner wall of the mask. With the increase of the attached small water droplets, the small water droplets are easy to gather into water droplets and fall. ...

Problems solved by technology

[0005] The purpose of the present invention is to drive the dehumidification drive gear to rotate through the drive shaft, and the mutual cooperation between the dehumidification drive gear and the driven gear makes the reciprocating swing of the telescopic sleeve connected to the dehumidification sponge clean the water vapor on the inner wall of the mask. Drive the antibacterial slave gear to rotate, so that the expansion box on the rotating frame and the cleaning sponge on the outside of the cleaning plate can absorb the water vapor at the connection between the intake pipe, exhaust pipe and the mask, and prevent the growth and adhesion of bacterial dust at the connection port. Drive the reciprocating lead screw to rotate through the drive shaft, so that the telescopic hose can quickly transmit the exhaust gas exhaled by the patient inside the mask to the inside of the exhaust pipe, so as to solve the problem of discomfort caused by the water vapor inside the mask gathered into water droplets and then entering the patient's trachea with breathing, and the connection port of the mask. Due to the problem that there is more water vapor, bacteria are easy to breed and the exhaust gas discharge speed is slow, which affects the anesthesia effect, an inhalation anesthesia machine for general anesthesia is proposed
