Abstract

The invention discloses an electronic evaporation device for inhalation anesthetics. The device comprises a liquid anesthetic storage unit, a differential pressure liquid level meter, an electromagnetic valve, a proportional valve, a flow sensor, a temperature sensor, a carrier gas and anesthetic gas path differential pressure sensor, an altitude sensor, an electric control anesthetic concentration adjusting disc and an electronic control system. After the technical scheme is adopted, the liquid level of a liquid anesthetic can be accurately monitored through an anesthetic gas evaporation tankby means of a differential pressure sensor, and errors caused by human eye observation are avoided; the flow of anesthetic gas is measured through the flow sensor, heat brought away by vaporization of the liquid anesthetic is estimated, data of the liquid level sensor is also used, the data is fed back to an electric control heating system, and the constancy of the temperature in the electronic evaporation device is further improved; through an altimeter, the altitude is obtained; a motor is utilized to drive the anesthetic concentration adjusting disc to correct the anesthetic gas concentration change caused by the altitude.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an electronic vaporization device for inhalation anesthetics. Background technique [0002] The anesthetic is inhaled through the respiratory tract to inhibit the central nervous system, causing the patient to temporarily lose consciousness without feeling pain all over the body. It is the main method of general anesthesia. The depth of anesthesia is related to the partial pressure of the drug in the brain tissue. Or after being metabolized in the body, the patient gradually regains consciousness without leaving any sequelae. Inhalation anesthesia has little metabolism and decomposition in the body; most of it is excreted from the lungs in its original form, so inhalation anesthesia is easy to control, relatively safe and effective, and is a commonly used method in anesthesia. [0003] Anesthetics are usually shipped in liquid form in suitable containers for the safety of patients...
