A continuous plasma collection method and collection device used therefor

Abstract

The invention discloses a continuous plasma collection method and a collection device thereof. According to the scheme, the plasma collection method and the collection device have the beneficial effects that continuous separation and collection of blood components are achieved, time required by a collection process is shortened, and collection efficiency and medicine liquid return efficiency for adverse reactions are improved; and meanwhile, the operating state of the entire device is monitored, so that the operating safety, stability and service life of the device are improved.

Description

technical field [0001] The invention relates to a plasma collection device and a continuous plasma collection method based on it. Background technique [0002] In the process of plasma collection, after the single-cycle plasma collection is completed, the blood components are not directly reinfused, but the blood components are transferred, and the anticoagulated whole blood is collected in backup during the transfer process, and the backup collection is performed when the blood components are reinfused The anticoagulated whole blood enters the separation device to start the next separation cycle, which is called continuous collection process. In a continuous collection process, the separator continues to rotate until a preset volume of plasma is collected. [0003] The acquisition process of the continuous acquisition process and the devices used in the prior art have the following problems: [0004] 1. The collection process takes a long time, and the amount of isolated ...

AI Technical Summary

Problems solved by technology

[0004] 1. The collection process takes a long time, and the amount of isolated blood at one time is large, which is likely to cause adverse reactions

[0005] 2. During the collection process, if you encounter lipid slurry or the liquid medicine used to deal with adverse reactions, it needs to be returned to the human body through a centrifugal 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. 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

[0007] 4. 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
