Anesthetic atomizing device for surgical anesthesia

Abstract

The invention relates to an anesthetic atomizing device for surgical anesthesia. The anesthetic atomizing device effectively solves the problems that an existing anesthetic atomizing device is single in atomizing function and cannot be adaptively adjusted according to different conditions of patients. According to the technical scheme, the device can correspondingly adjust the amount of anesthetic atomized gas fed into the airway of a patient according to the change of the exhaled air amount of the patient, so that the supply amount of the anesthetic atomized gas is adjusted according to different anesthetic stages of the patient. The situation that atomized gas is directly heated and becomes dry is avoided, and part of liquid medicine volatilized when the anesthetic liquid medicine is heated can be recycled (waste of the anesthetic liquid medicine is avoided).

Description

technical field [0001] The invention belongs to the technical field of surgical anesthesia, in particular to an anesthetic atomizing device for surgical anesthesia. Background technique [0002] Anesthesia is the use of drugs or other methods to temporarily lose the patient's overall or local sensation in order to achieve painless surgical treatment. Nowadays, anesthesiologists usually use anesthesia nebulizers in operating rooms for anesthesia operations, which use air suction, etc. The principle makes the anesthetic liquid become misty (dispersed into tiny mist or particles) and enters the patient's airway along with the carrier gas to achieve the effect of anesthesia; Anesthesia is divided into anesthesia induction (the patient is awakened to unconsciousness, which occurs before the operation), anesthesia maintenance (the patient is continuously inhaled anesthesia atomized gas to keep the patient under anesthesia), and anesthesia recovery (the anesthesia will be stopped ...

AI Technical Summary

Problems solved by technology

That is, during the initial period of anesthesia, the patient's breathing is deep and fast (large inspiratory volume), and when entering the anesthesia maintenance stage, the patient's breathing becomes shallow and slow (small inspiratory volume). The supply of anesthesia nebulized gas is automatically adjusted according to the stage of anesthesia, so that when entering the anesthesia maintenance stage, more gas than the patient needs will enter the trachea (easy to cause tracheal spasm, dyspnea, breathlessness and other symptoms);
