Anesthesia induction method and device and anesthetic machine

Abstract

The invention discloses an anesthesia induction method and device and an anesthetic machine. The method comprises the following steps of receiving an induction command, and according to the inductioncommand, enabling a machine to enter an induction process; after the induction command is received, executing an oxygen supply and denitrification stage, and rinsing nitrogen in a loop and a breathingtube; after the nitrogen is rinsed for a preset time, executing a medicine induction stage, according to the current autonomous respiration frequency of a patient, starting a controller for controlling ventilation, and according to the current exhalation oxygen concentration and the current oxygen inspired concentration of the patient, giving out trachea cannula reminding; and after the breathingtube is reconnected, executing a trachea cannula stage, according to the current ventilation data, the current inhalation carbon dioxide concentration value and the current exhalation carbon dioxideconcentration value, when the ventilation is determined to be valid, giving out intubating completion reminding, or else giving out anew intubating reminding. The anesthesia induction method can effectively assist in anaesthetization doctors to complete an anesthesia induction process, so that the working efficiency is improved, the anaesthetization safety and reliability are effectively improved,and anaesthetization is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of medical anesthesia, in particular to an anesthesia induction method, device and anesthesia machine. Background technique [0002] In the related art, in the common general anesthesia induction, after the anesthesiologist administers the drug, the patient's consciousness gradually disappears, and the spontaneous breathing gradually weakens to stop, so the anesthesiologist needs to assist the patient to breathe through the mask. When the anesthesiologist believes that the patient's muscles are sufficiently relaxed (if muscle relaxants are used) and oxygen reserves are sufficient to tolerate a pause in ventilation during intubation, perform tracheal intubation or placement of a laryngeal mask and confirm correct placement of the artificial airway Afterwards, machine-controlled ventilation was started, and anesthesia maintenance was entered. [0003] However, when the anesthesiologist pinches the balloon for...

Problems solved by technology

[0003] However, when the anesthesiologist pinches the balloon for mask ventilation, the airway pressure may be too high, and the gas may enter the stomach and cause the risk of reflux and aspiration; Support the jaw and ask an assistant to assist ventilation; or when the mask leaks and the fresh gas flow rate is small, the balloon is easy to collapse, and the anesthetist needs to press the quick oxygenation button to fill the balloon, resulting in cumbersome and inconvenient operations during the induction process. It not only reduces work efficiency, but also has low safety and reliability, which needs to be solved urgently
