The main body 1 is tubular, and the plurality of liquid outlet members 2 are connected to the main body 1 and arranged along the tubular length direction of the main body 1. In practical application, the number of the liquid outlet member 2 and the on-off valve 3 can be determined according to practical situations.

Specifically, the main body 1 is formed with a liquid feeding channel 11, each liquid discharging member 2 is formed with a liquid discharging channel 21, each liquid discharging channel 21 is connected with the liquid feeding channel 11 through a switch valve 3, and the switch valve 3 controls the on-off of the corresponding liquid discharging channel 21 and the liquid feeding channel 11, that is, each liquid discharging channel 21 is communicated with the liquid feeding channel 11, and the communication position of each liquid discharging channel 21 and the liquid feeding channel 11 is provided with a switch valve 3, so that the on-off control of the liquid discharging channel 21 can be realized by driving the switch valve 3. Moreover, since each liquid outlet channel 21 is communicated with the infusion channel 11, the plurality of liquid outlet members 2 are preferably integrally formed with the main body 1 (for example, integrally formed by injection molding), so that the plurality of liquid outlet members 2 can be seamlessly connected with the main body 1, and leakage caused by assembly gaps between the liquid outlet members 2 and the main body 1 is avoided.

When the swelling anesthesia operation is performed, the output ends (i.e. needle points) of a plurality of needle members (such as medical needles; the needle members are used for puncturing the subcutaneous tissues of the patient to realize the injection operation of liquid) are inserted into the subcutaneous tissues of the patient, and then the input ends of the needle members are connected with the liquid outlet member 2 by using the water pipes, so that the liquid in the infusion channel 11 is injected into the subcutaneous tissues of the patient through the liquid outlet channel 21, the water pipes and the needle members.

In particular, the body part 1 is provided with at least one port for injecting an external liquid (e.g. an anesthetic agent) from one end of the infusion channel 11 into the infusion channel 11, and the port is preferably oriented in the longitudinal direction of the infusion channel 11.
