Specifically, the plugging piece is made of a material which can expand after absorbing water.
Specifically, the plugging piece is annular after being expanded.
Specifically, the opening end of each branch pipe is communicated with a guide piece, and the guide piece is in a conical shape with the diameter gradually reduced towards the opening end.
Specifically, the guide piece is made of a material which can expand after absorbing water.
Specifically, the outer wall surface of the guide part is spiral.
Specifically, the adapter with three way valve threaded connection.
Compared with the prior art, the utility model has the beneficial effects that: the blood circulation device is provided with the three-way valve, and the flow passage ports of the three-way valve are connected with branch pipelines, so that blood can flow in multiple directions through the branch pipelines through the three-way valve; the three-way valve can be closed to cut off the blood circulation, or the three-way valve is turned by 90 degrees to change the flow direction of the blood, so as to prevent the blood seepage from obstructing the suture operation of other ruptured branch blood vessels; or rotating the three-way valve at a particular angle to vary the flow of blood therethrough.
In addition, each branch pipeline is the spiral folding form, is favorable to reducing the volume and is convenient for storage and transportation, and can be according to the length that the required bridge of blood vessel, stretch the heliciform branch pipeline in order to reach the sufficient length and bridge the two disconnected end blood vessels.
