Anesthesia respirator evaporation device

Abstract

The invention relates to an anesthesia respirator evaporation device. The problems are effectively solved that drawdown of liquid levels of current anesthesia evaporators influences evaporation speed,the evaporation speed and the amount of carried gas cannot be matched and adjusted, and the evaporation speed is low. According to the technical scheme, the anesthesia respirator evaporation device includes an evaporation chamber, multiple layers of evaporating dishes are arranged inside the evaporation chamber, a drug storage cavity is formed above the evaporation chamber, a vertical pipe whichpenetrates through the evaporating dishes in sequence is installed inside the evaporation chamber, the upper end of the vertical pipe is communicated with the bottom of the drug storage cavity, a plurality of plungers which are in one-to-one correspondence to the evaporating dishes and capable of moving up and down are installed inside the vertical pipe, and the plungers move up and down and thencan control whether or not medical liquid is stored inside the corresponding evaporating dishes. The liquid level of the anesthesia respirator evaporation device is constant; according to the amount of the carried gas, the working conditions of the evaporating dishes on each layer can be selectively started and closed, so that the evaporation efficiency of the medical liquid inside the evaporationchamber is matched with the amount of the carried gas; the space utilization rate of the evaporation chamber is high, and the anesthesia respirator evaporation device is compact in structure, small in size and high in evaporation speed.

Description

technical field [0001] The invention relates to the field of anesthesia equipment, in particular to an evaporation device for an anesthesia ventilator. Background technique [0002] Breathing anesthesia machine refers to the equipment that evaporates the anesthetic drug and mixes it with the carrier gas for the patient to breathe, and anesthetizes the patient. The device is to soak the lower end of the drug core in the anesthetic liquid in the evaporation chamber. The liquid spreads upward through the siphon effect. The concentration of the anesthetic vapor in the inhalation gas is adjusted by the flow ratio of the diluting gas; as the evaporation progresses in this type of device, the amount of liquid medicine in the evaporation chamber decreases, the liquid level drops, and the siphon speed slows down, which affects the evaporation speed and makes the vapor in the carrier gas Insufficient anesthetic concentration; secondly, the evaporation area of ​​the anesthetic solutio...
