The video shows the appearance and relative dimensions of the working head of the auxiliary blood circulation pump BIOPUMP before the start of tests at the stand. Such pumps help patients who are waiting for heart transplantation, and are also used in resuscitation. In the United States of America about 300,000 operations for the installation of auxiliary circulation pumps are carried out annually.
BIOPUMP is tested at the stand. The purpose of the tests is to find the optimal modes of operation of the pump, in which the risk of thrombus formation is minimal.
The coagulation system was activated during the operation of BIOPUMP. The macroscopic fibrin clots, visible by the naked eye, were formed inside the working pump head. Such clots are able to disrupt the normal operation of the pump, or lead to serious complications and thrombosis.
The coagulation system was activated during the operation of BIOPUMP. It can be seen that the thrombi formed during the test completely blocked the outlet of the working head of the pump, thereby violating its operation.
