Description

A blood perfusion circuit based on Braun blood purification machine

technical field

The utility model relates to the technical field of medical supplies, in particular to a blood perfusion pipeline based on a Braun blood purifier.

Background technique

Hemoperfusion is a method of blood purification. Hemoperfusion is designed to remove macromolecular substances, such as drug poisoning, high bilirubin, and severe infections. For such patients, the current clinical strategy of hemoperfusion is 3 times/day, and double hemoperfusion is performed each time. Due to the limitation of the hemoperfusion circuit, double hemoperfusion can only be performed in series, but the effect of series is obviously low. Because of 2 separate hemoperfusions, in addition, 2 separate hemoperfusions must consume 2 sets of tubing; so neither series nor 2 separate hemoperfusions are suitable for the current treatment strategy.
