Inhalation type anaesthesia device

Abstract

The invention discloses an inhalation type anaesthesia device. The inhalation type anaesthesia device comprises a box body, wherein a box door is rotatably connected to the outer side of the box bodythrough a hinge; trundles are arranged at the bottom of the box body; an oxygen tank is fixedly mounted on one side in the box body; a drug evaporation case is arranged at the top of the oxygen tank;an evaporating heater is arranged at the bottom of the drug evaporation case; the drug evaporation case and the evaporating heater are fixedly mounted in the box body; a gas mixing cylinder is fixedlymounted at the middle part of the box body; a piston is in sliding connection to the bottom of an inner cavity of the gas mixing cylinder; and an electric push rod is arranged at the bottom of the gas mixing cylinder. According to the inhalation type anaesthesia device disclosed by the invention, the bottom end of a rotating rod is in spiral sleeving combination with a cannula, and then during continuous lifting of the piston, a rotating disk and a lever at the top of the rotating rod are driven to rotate to sufficiently stir and mix oxygen and drug anesthetic gas inhaled in the gas mixing cylinder, so that favorable anaesthesia effects of the device can be guaranteed, and the anaesthesia performance of the device is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an inhalation anesthesia device. Background technique [0002] Anesthesia is a variety of methods used to eliminate pain, ensure patient safety, and create good surgical conditions during operations or diagnostic inspections. It is also used to control pain. It is divided into inhalation anesthesia according to the way anesthetics enter the body. , intravenous anesthesia (general anesthesia) and basic anesthesia, in which both intravenous anesthesia and basic anesthesia use syringes, this method will increase the fear of patients, make them mentally stressed and inconvenient for follow-up treatment, and inhalation anesthesia is the use of The anesthesia method in which the gas anesthetic enters the human body from the respiratory tract is non-invasive and painless. In the actual use of inhalation anesthesia, the agent needs to be evaporated and mixed with oxygen for use b...

AI Technical Summary

Problems solved by technology

[0003] The prior art has the following deficiencies: in the existing inhalation anesthesia devices, most of the anesthesia gas and oxygen are directly drawn out and mixed by pipelines, and the patients inhale them by themselves, and the mixing efficiency of anesthesia gas and oxygen is not high, and the gas supply effect is poor , which reduces the actual anesthetic performance, has certain limitations and dangers
