Integrated injection device for animal experiment

The utility model relates to the technical field of experimental instruments, in particular to an integrated injection device for animal experiments. The device comprises a device body which comprises a liquid conveying pipeline. One end of the infusion pipeline is connected with normal saline through a corresponding valve assembly, and the other end of the infusion pipeline is connected with an infusion needle; a plurality of communicating interfaces are sequentially formed in the side wall of the liquid conveying pipeline in the axial direction, and the communicating interfaces are connected into corresponding experimental liquid medicine through corresponding valve assemblies. Compared with the prior art, related experimental liquid medicine needed by experimental researchers in the injection stage of animal experiments can be concentrated at one position, and the corresponding valve assembly is arranged, so that injection of the animal related experimental liquid medicine by a single experimental research
