An intermittent plasma collection device

Abstract

The invention discloses an intermittent type plasma collecting device which comprises a collecting module, an anticoagulation module, a separating module, a collecting module, a medicine conveying module, an anticoagulation whole blood pump pipe and an integrated module.The integrated module is provided with a plurality of connectors which are connected with all the modules and the pump pipe respectively.A monitoring module and a filter cavity are arranged in the integrated module.The intermittent type plasma collecting device has the advantages that the time required for backward conveying flow in the collecting process is saved, the collecting efficiency and the liquid medicine backward conveying efficiency for adverse reactions are improved, the running state of the whole device is monitored, and the running safety and stability of the device are improved.

Description

technical field [0001] The present invention relates to a medical device, especially a device for whole blood collection-separation-plasma collection-component reinfusion. Background technique [0002] Plasma collection requires the matching of plasma collection equipment and collection consumables. After venipuncture of the human body through the blood collection needle of the consumable, the blood and other liquids in the consumable channel are driven by the collection equipment to flow, so that the anticoagulated blood enters the centrifuge driven by the centrifuge and rotates at a high speed. Centrifuge the anticoagulated blood in the centrifuge cup, and the centrifuged plasma enters the plasma collection bag. After the single cycle is completed, the centrifuge stops rotating, and the blood components in the centrifuged separation cup are reinfused. After the reinfusion is completed, the next single cycle is carried out. Circulation until a set amount of plasma is collec...

AI Technical Summary

Problems solved by technology

[0004] 1. The monitoring modules of the acquisition system are many and scattered, and the equipment is large in size. The installation of consumables on each monitoring module needs to be done manually, which limits the efficiency of operators

[0005] 2. During the collection process, if encountering lipid slurry or medical liquid for dealing with adverse reactions, it needs to be returned to the human body through a centrifuge separation cup. This process reduces the collection efficiency and is not conducive to relieving the adverse reactions of the collected objects as soon as possible.

[0006] 3. In the collection process, the working status of the separation module lacks pressure monitoring means, which is not conducive to the operator's grasp of the collection situation
