Anesthesia evaporation tank accurately controlling spraying concentration

Abstract

The invention belongs to the field of medical apparatuses and instruments, and discloses an anesthesia evaporation tank accurately controlling the spraying concentration. The anesthesia evaporation tank comprises a tank body, a heating device is arranged at the bottom of an inner cavity of the tank body, a temperature sensor is arranged at the bottom of the right side of the inner cavity of the tank body, a liquid feeding pipe is movably arranged at the top of the left side of the tank body, an air discharging pipe is arranged at the top of the tank body, and is movably sleeved with an adjusting valve, and a spraying head is connected to the other end of the air discharging pipe; medicine is added into the inner cavity of the tank body from a hopper, a plug body is plugged into after medicine adding is end, the liquid feeding pipe is rotated, a liquid inlet of the hopper is formed downwards, and dust is prevented from entering an inner cavity of the hopper; a rolling wheel moves left and right, extrusion force of the rolling wheel for the air discharging pipe is changed, the flowing speed of steam in the air discharging pipe is adjusted; by rotating a cover, air discharging openings of the cover are in contact with three groups of silica gel rings in sequence, the air discharging openings are plugged through the silica gel rings, the quantity of the air discharging openings capable of discharging air is changed, and the spraying concentration is changed.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to an anesthesia evaporation tank with precise control of spray concentration. Background technique [0002] As the core component of the anesthesia machine, the anesthesia evaporation tank can effectively evaporate the anesthetic liquid, and can accurately inject the anesthetic into the anesthesia breathing circuit at a certain concentration. The accuracy of the evaporation tank not only marks the technical level of the anesthesia machine itself, but also relates to the success or failure of inhaling anesthesia, and directly relates to the safety of the patient. Modern anesthetic vaporizers require convenient operation, convenient dosing, absolute safety, temperature, flow, and pressure compensation, and precise control of anesthetic vapor concentration. [0003] With the trend of high body weight in modern humans, the existing evaporator can not adapt to the rapid and large-dose supply ...

AI Technical Summary

Problems solved by technology

[0003] With the trend of high body weight in the modern human body, the existing evaporation tank cannot adapt to the fast and large-dose supply of anesthetic drugs, and the change of heating temperature will also affect the vapor concentration. In the actual control process, it is difficult to maintain the concentration of anesthetic drugs to achieve high-precision and stable delivery. , resulting in unstable drug concentration and inaccurate administration concentration, which in turn makes the concentration of anesthetic vapor delivered to the patient unable to be accurately monitored
