Description

Medical breathing type anaesthesia device

Technical Field

The invention relates to the technical field of anesthetics, in particular to a medical breathing type anesthetic machine.

Background

Anesthesia is a reversible functional inhibition of the central and peripheral nervous systems, produced by drugs or other means, characterized primarily by loss of sensation, particularly pain sensation, which is frequently used in various clinical procedures.

General anesthesia, general anesthesia for short, means that anesthetic enters into the body through respiratory tract inhalation, vein or intramuscular injection, produces the temporary inhibition of the central nervous system, the clinical manifestations are that the mind disappears, general pain sense disappears, forgets, reflex suppression and skeletal muscle relaxes, the degree to the inhibition of the central nervous system is related to the concentration of medicine in the blood, and can be controlled and regulated, this inhibition is totally reversible, after the medicine is metabolized or is discharged from the body, the mind and various reflexes of the patient recover gradually; the inhalation anesthetic is a volatile liquid or gas, enters a human body through a respiratory tract to play a role of anaesthesia from shallow to deep, has the characteristics of strong anaesthesia function, high controllability and the like, and has a leading position in general anaesthesia and the maintenance process of anaesthesia.

However, the following problems generally occur in the existing general anesthesia operation:

1. after anaesthetizing patients, residual anesthetic gas in the anesthetic corrugated pipe can overflow and disperse to the air, so that medical workers are injured for a long time, and the harm of the overflowed anesthetic gas to the environment is very serious.

2. Although the prior art is relatively perfect in anesthesia operation, accidents can also occur, when a patient receives anesthesia, accidents such as sudden respiratory arrest and sudden cardiac arrest occur due to excessive depth of anesthesia or other reasons, at the moment, emergency oxygen supply operation needs to be carried out on the patient, oxygen is inhaled to a mask of the patient, a stabilizing agent is injected, and precious time is wasted due to switching of the anesthesia mask and the oxygen mask, so that rescue time of the patient is influenced.

3. Current suction-type anesthesia lets the patient inhale after mixing oxygen and anesthetic gas usually to when playing the anesthesia effect, guarantee that patient's oxygen is supplied with, prevent the patient oxygen deficiency, but in oxygen among the current anaesthesia device and anesthetic gas directly input anaesthetic mask through the gas-supply pipe, be difficult to the misce bene, certain potential safety hazard has.

Therefore, the present invention provides a medical respiratory anesthetic apparatus to solve the problem.
