An annular separator applied to a continuous plasma collection device

Abstract

The invention discloses an annular separator applied to a continuous blood plasma collection device. The separator adopts a hollow cylindrical structure, a separation cavity is formed in the separator, a central channel is formed in the center of the separator and is connected with the separation cavity through a liquid connection channel, an isolation wall with one end connected with an outer wall is arranged in the liquid connection channel and divides the liquid connection channel into an inlet channel and an outlet channel, and a baffle extending towards the outer wall is further arranged in the liquid connection channel and divides the outlet channel into a first outlet channel and a second outlet channel. According to the scheme, the annular separator is characterized in that the annular separator can be matched with a separating machine to quickly separate blood plasma and collect separated substances in a classified manner, the collection-separation time of the blood plasma is shortened, and the probability of adverse reactions is reduced.

Description

technical field [0001] The invention relates to a structural component of a medical device, in particular to an annular separator applied to a continuous plasma collection device. 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 proc...

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
