Background

The most commonly used induction method for general anesthesia by anesthesiologists is that multiple (e.g. 4-5) anesthetic drugs and adjuvant drugs are sequentially injected through a pre-established venous access of a patient in a short time (about 30s), so that the patient can be in an operable state after anesthesia induction with sufficient sedation, analgesia and muscle relaxation.

During specific operation, an anaesthetist connects a plurality of syringes pre-filled with anaesthetics with a three-channel rotary valve on a venous transfusion channel of a patient in sequence and injects a plurality of medicines in sequence. However, this rapid induction process has several drawbacks due to the need to repeatedly connect (disconnect) multiple syringes to the three-way stopcock for administration:

1. the liquid medicine in the vein passage and the syringe is easy to exosmose in the administration process;

2. small bubbles are easily generated in the three-channel rotary valve in each connection process;

3. the operation of the anaesthetist is quite complicated, and the operation burden is increased;

4. most importantly, repeated connection of the syringe to the three-way stopcock requires repeated access by the anesthesiologist to the three-way stopcock, which increases the risk of bacterial contamination of the patient's venous access.

At present, most of the intravenous induction processes adopt the administration mode, and the existing problems need to be solved urgently. Although individual devices are also improved in a targeted manner, the essence that the front ends of the syringes need to be connected one by one is not changed, the operation procedure is still complicated, and the risk of bacterial contamination of the front ends of the syringes still exists.
