Background

The induction anesthesia refers to the time process that after preoperative preparation and preparation of various articles of a patient are completed, an anesthesiologist uses an intravenous anesthetic and injects the intravenous anesthetic into the body of the patient in a transfusion mode, and the patient gradually enters a general anesthesia state from waking. The dosage of the anesthetic is required to be comprehensively evaluated and used according to the physical condition of the patient during induction anesthesia, after the dosage of the anesthetic is accurately calculated and applied, the fluctuation range of the blood pressure and the heart rate of the patient is small, and the fluctuation range comprises sedative drugs, analgesic drugs, muscle relaxant drugs and anticholinergic drugs which are respectively injected into the body of the patient according to different sequences.

However, the following disadvantages still exist when injecting multiple drugs into a patient's body:

1. when injecting corresponding anesthetic, medical care personnel are required to insert a syringe needle into an anesthetic reagent bottle to extract corresponding liquid medicine, after extraction is finished, a doctor is required to push out the anesthetic in the syringe according to the physical condition of a patient, the residual anesthetic in the syringe is left in the syringe through visual inspection, and the residual anesthetic in the syringe is judged through visual inspection, so that the accuracy of the later-period anesthetic injection is insufficient, the phenomenon of excessive or insufficient anesthetic injection is easy to occur, and the later-period operation is influenced;

2. because the types of the medicines to be injected are more, the medicines are required to be injected into the body of a patient respectively according to different sequences, and the medicines are uniformly placed, the medicines cannot be sequentially placed according to the injection sequence of the medicines, so that the injection sequence confusion of the medicines is easy to occur when the corresponding medicines are injected at the later stage;

3. when extracting the liquid medicine in inserting the syringe into the reagent bottle, there is the bacterium in the reagent bottleneck, when the syringe needle inserts in the reagent bottle, take the bacterium into the liquid medicine easily, and then can bring the hidden danger for the patient when later stage pours into the liquid medicine into the patient internal.
