Abstract

The invention discloses a closed and pre-charge feedback type extracorporeal circulation pipeline for rats, which belongs to the technical field of experimental auxiliary equipment. The technical scheme is that the closed and pre-charge feedback type extracorporeal circulation pipeline for the rats is characterized by comprising a venous drainage tube, a blood storage chamber, a rolling pump connecting tube, a heat exchanger, a membrane oxygenator and an arterial draft tube. One end of the venous drainage tube is used for connecting veins of the rats, the other end is connected with the bloodstorage chamber; the blood storage chamber is connected with a blood inlet of the heat exchanger through the rolling pump connecting tube; the rolling pump connecting tube is externally connected witha rolling pump; a blood outlet of the heat exchanger is connected with a blood inlet of the membrane oxygenator through a butt tube, and a blood outlet of the membrane oxygenator is connected with the artery puncture needle of the rats through the artery draft tube, and therefore the closed and pre-charge feedback type extracorporeal circulation pipeline for the rats has the advantages that the external circulation tube is closed, and the situations are avoided that venous drainage is insufficient, and the blood storage chamber and other pipelines are easy to intake air, the overall pre-charge of the pipeline, and the like.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of experimental auxiliary equipment, in particular to a small closed pre-charge feedback type extracorporeal circulation pipeline for rats. Background technique [0002] Cardiac surgery and critical care medicine have done research on rat extracorporeal circulation and hypothermic circulatory arrest models. Most of the animal experiments are for experimenters to buy membrane lungs, heat exchangers, etc., and build pipelines by themselves. A set of finished products, high efficiency, simple operation, Low-cost pipelines can greatly help experimental progress, and such simple and efficient pipelines are currently lacking. [0003] At present, most of the domestic and foreign literature reports use open extracorporeal circulation in rats, and the amount of priming is large, the model establishment time is long, the intermediate operation is cumbersome, and the success rate of the model...
