Description

Anesthesia maintenance device for clinical anesthesia

Technical Field

The invention relates to a medical instrument, in particular to an anesthesia maintenance device for clinical anesthesia.

Background

The general anesthesia is divided into three stages of anesthesia induction, anesthesia maintenance and anesthesia recovery. Anesthesia induction refers to the transition from waking to sleeping. After the patient enters the operating room, a nurse opens a venous access (namely, needle insertion transfusion), an anesthesiologist is connected with monitoring of electrocardiogram, blood pressure, blood oxygen saturation and the like, and a mask inhales oxygen. The anesthesiologist may then begin anesthesia induction. An anesthesiologist can intravenously inject general anesthetic or inhale anesthetic gas to a patient, and the patient can disappear 3-5 minutes after administration and enters a sleep state from waking. Under the general anesthesia state, because no consciousness and general muscle are relaxed, the patient loses the breathing strength, and the spontaneous breathing usually disappears, therefore, after the patient enters the general anesthesia state, an anaesthetist can carry out tracheal intubation operation, namely, a tracheal catheter is inserted into the trachea of the patient through the oral cavity or the nasal cavity of the patient under the assistance of intubation instruments such as a laryngoscope, the other end of the tracheal catheter is connected with an anaesthesia machine, and the anaesthesia machine delivers oxygen to the patient through the tracheal catheter to help the patient to breathe.

After the patient enters the anesthesia maintenance state, the anesthesiologist can continuously inhale the anesthetic gas into the patient through the anesthesia machine or continuously infuse the anesthetic drug through the intravenous route, so that the patient is continuously in the anesthesia state. At this point, the procedure can begin. The duration of the whole anesthesia depends on the duration of the operation. The operation time is long, and the anesthesia maintenance time is long; the operation time is short, and the anesthesia maintenance time is also short. When the operation is finished successfully, the anaesthetist stops using the anaesthetics medicine, and the patient enters the anaesthesia recovery period. The concentration of the anesthetic is gradually reduced as the metabolism of the anesthetic in the patient is discharged. When the concentration in the anesthetic drug is reduced to a certain degree, the patient can recover spontaneous breathing, consciousness can be conscious, and at the moment, an anesthesiologist can pull out the tracheal catheter, continue to inhale oxygen to the mask of the patient and suck oral secretion. When the spontaneous respiration of the patient is recovered well, the consciousness is completely clear, the distinguishing capability is good and the vital signs are stable, the standard of anesthesia and recovery from the room is achieved, and the patient can return to the ward.

Need carry out intensive mixing to anesthetic gas and oxygen at the anesthesia in-process, it is inhomogeneous to prevent that the anesthetic gas from mixing the inequality anesthesia that leads to the inequality or supply medicine during the anesthesia, and anesthesia in-process owing to adopt the intubate to carry out the anesthesia, inevitable existence has some patients to have foreign body sensation, if there is palirrhea and can block up patient's trachea and esophagus this moment, need in time discharge secretion and palirrhea thing, could guarantee to perform the operation normally.
