Abstract

The invention discloses an evaporator and an anesthesia machine with the same. The evaporator comprises a body, an evaporator valve seat and a liquid level display unit. An evaporation chamber is arranged in the body and provided with a first air inlet and a first air outlet. The body is provided with a second air inlet communicated with the first air inlet of the evaporation chamber and a second air outlet communicated with the first air outlet of the evaporation chamber. The evaporator valve seat is mounted on the body. The liquid level display unit is a resin tube and arranged on the body. According to the evaporator, the liquid display unit uses the resin tube having the characteristics of low thermal conductivity, high light transmittance, high impact resistance, light weight, ultraviolet ray resistance, stable optical property and the like, so that the liquid level display unit of the evaporator is high in fogging resistance, high in transparency, unbreakable and wide in anti-solvent range when compared with a liquid level display unit using a glass tube.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, to a vaporizer and an anesthesia machine with it. Background technique [0002] The vaporizer is an important part of the anesthesia machine, which is used to precisely control the mixture of the evaporated gas of the anesthetic agent and the fresh gas, so that it can be accurately output to the patient according to the concentration set by the anesthesiologist. In actual use, in order for the user to know the amount of anesthetic liquid in the evaporator, a liquid level display device is designed. The main display component in the existing evaporator device is a glass tube. Low, not UV resistant, prone to fogging due to weather changes. [0003] In the actual application of the evaporator, fresh gas enters the evaporator, and the gas is divided into two paths. One path is called the carrier gas entering the evaporation chamber, and the other path is called the by...
