Preferably, the mixing part includes a driving source and a mixing member rotated by the driving source.
Preferably, the number of the liquid storage containers is two, and the multi-way valve is a three-way valve.
The utility model has the advantages that:
1. the peristaltic pump is adopted to avoid the problem of pollution caused by mixing of the solution before flowing into the multi-way valve or liquid backflow, and simultaneously, the peristaltic pump parameters can be regulated according to actual needs to accurately control the perfusion flow speed and flow, so that the operability is high;

Detailed Description
The following describes the embodiments of the present utility model in further detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present utility model and are not intended to be limiting.
In the description of the present utility model, it should be noted that the azimuth or positional relationship indicated by the terms "inner", "outer", etc. are based on the azimuth or positional relationship shown in the drawings, and are merely for convenience of describing the present utility model and simplifying the description, and are not indicative or implying that the apparatus or element in question must have a specific azimuth, be constructed and operated in a specific azimuth, and thus should not be construed as limiting the present utility model.
In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.
Furthermore, in the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more.
As shown in fig. 1, the utility model provides a perfusion device for experimental animals, which comprises a plurality of liquid storage containers 1 and a multi-way valve 4, wherein the liquid storage containers 1 are respectively communicated with a perfusion tube 2, and the multi-way valve 4 is a confluence valve and comprises a plurality of inlet ends and an outlet end. The infusion tubes 2 are connected with the inlet ends of the multi-way valves 4 one by one through peristaltic pumps 3, and the outlet ends of the multi-way valves 4 are communicated with the injector 7. The multi-way valve 4 is further provided with a mixing section 5 for uniformly mixing the liquids. Specifically, the syringe 7 is an injection needle; the multi-way valve 4 is provided with a mixing chamber 6 near the outlet end, and the mixing section 5 is arranged in the mixing chamber 6. The mixing part 5 comprises a driving source, which may be a motor or a cylinder, and a mixing element, which may be a mixing drum, a mixing shaft or a mixing wheel with blades, which is driven by the driving source to rotate. The liquid storage container 1 is a liquid storage bottle or a liquid storage bag.
The working principle of the utility model is as follows:
when in use, a worker pours the perfusion solution into each liquid storage container 1, starts the peristaltic pump 3, discharges the gas in the pipeline, and fully washes the pipeline. The injection needle of the injector 7 is inserted into the heart of an experimental animal, then the working parameters of the peristaltic pump 3 are regulated according to actual needs to control the flow rate and the flow rate of the solution in each infusion tube 2, the liquid in the liquid storage container 1 enters the mixing chamber 6 through the infusion tube 2, the peristaltic pump 3 and the inlet end of the multi-way valve 4, the liquid can be uniformly mixed in the mixing chamber 6 by the mixing part 5, and finally the mixed liquid enters the experimental animal body through the outlet end of the multi-way valve 4 and the injector 7, so that the perfusion work is completed. In the whole perfusion process, a closed flow is formed from the liquid storage containers 1 to the injectors 7, and the multi-way valve 4 is adopted, so that on one hand, the problems of air bubbles, time and labor waste and the like caused by the simple perfusion of the injectors can be avoided, and on the other hand, the experimental requirements of the alternative perfusion of the liquid in the liquid storage containers 1 can be met. The liquid flowing out of the multi-way valve 4 can be uniformly mixed by the matching mixing part 5, and the experimental result is more accurate.
