Abstract

The invention relates to a bubble extrusion machine used for plasma bags, and comprises a shell (1), a extrusion plate (2), a screw pulling mechanism used for pulling the extrusion plate (2), and a controller (6); the screw pulling mechanism comprises a screw (4), and a motor (5) used for pulling the screw (4); one end of the screw (4) is connected with the extrusion plate (2); the motor (5) is arranged in the shell (1) and controlled by the controller (6); the extrusion plate (2) is arranged outside the shell (1). By adopting the extrusion plate and the screw pulling mechanism, the invention can quickly squeeze air out of the plasma bags.

Description

technical field [0001] The present invention relates to equipment used in the separation of blood components. Background technique [0002] From blood collection to clinical application, blood will go through the process of collection, blood component separation, quick freezing, thawing, and clinical application. During the separation and quick-frozen storage of blood components, the purity of each blood component and the gas content will affect its quick-frozen storage. [0003] The blood is in the plasma bag, if the air in the bag cannot be completely discharged, the plasma bag will be easily broken during the quick freezing process. However, the existing blood component separation equipment does not have the function of automatic exhaust, and the air in the plasma bag can only be discharged by hand pressure or ordinary gravity exhaust clips, both of which are slow and accurate. Not high disadvantage. Contents of the invention [0004] The technical problem to be solv...
