Inhalational anesthetic evaporation device

Abstract

The invention relates to the technical field of medical devices, in particular to an inhalational anesthetic evaporation device. The device includes a first gas path, one end of the first gas path isprovided with an inlet, and the other end of the first gas path is provided with a mixed gas outlet; the first gas path is connected with a second gas path and a third gas path communicated with eachother; the connection portion of the second gas path and the first gas path is provided with a pressure monitoring diversion opening, and the other end of the second gas path is connected with a pressure monitoring unit; the connection portion of the third gas path and the first gas path is provided with a gas mixing hole; the pressure monitoring unit is connected with a seventh gas path through asixth gas path, one end of the seven gas path is communicated with an evaporation chamber unit, and the other end of the seven gas path is connected with an anesthetic gas control unit. The problemsare solved that the boiling point of desflurane is low, heat required by evaporation cannot be supplemented in time and added medicines are leaked, and meanwhile the evaporation control problem of clinical application of desflurane is solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an inhalation anesthetic evaporation device. Background technique [0002] Medically, the inhalable liquid anesthetic is inhaled from the respiratory tract through an evaporator, which can make the patient temporarily lose consciousness without pain. 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. After being excreted from the body or metabolized, 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 respiratory system in its original form, so inhalation anesthesia is easy to control, relatively safe and effective, and is the most commonly used method in general anesthesia. [0003] Currently known anesthetics are usually stored in liquid form in suitable con...

Problems solved by technology

Some models use flow monitoring and altitude monitoring for feedback control, such as patent application number 201710337242.3, which has high cost, complex control system, more fault points at the same time, and high maintenance and use costs
