The multichannel transfusion collector provided by the scheme is provided with at least three liquid inlets 11, so that transfusion requirements of patients can be met. In this embodiment, the number of the liquid inlets 11 is five, as shown in fig. 3, and the direction indicated by the arrow in the figure is the direction of the liquid flow inside the infusion set. The on-off switch 5 can control the on-off of the liquid inlet 11 matched with the on-off switch, so that the technical effect that different liquid inlets 11 can be independently opened or closed is achieved. Compared with the traditional three-way serial infusion apparatus, the scheme can effectively overcome the infection risk possibly occurring when the three-way serial infusion apparatus is connected in series, and meanwhile, the liquid inlets 11 are also arranged at different positions of the fixed main body 1, so that nursing staff can observe and operate conveniently.

In this embodiment, the fixing body 1 is further provided with an infusion tube 4, the infusion tube 4 is connected to the infusion port 12, and the liquid medicine delivered into the chamber through the liquid inlet 11 can be delivered into the patient through the infusion port 12 and the infusion tube 4.
