Blood component separation device and blood component separation method

Abstract

The invention discloses a blood component separation device, which is used for separating erythrocyte, platelet and plasma in blood. The blood component separation device comprises a first storage bag, a first filtering mechanism, a blood component separator, a second filtering mechanism, a third filtering mechanism and a second storage bag, wherein the first storage bag is used for storing blood; the first filtering mechanism is communicated with the first storage bag and is used for filtering the blood; the blood component separator is communicated with the first filtering mechanism; the second filtering mechanism is arranged in the blood component separator and is used for separating the platelet and the plasma to obtain the erythrocyte; the third filtering mechanism is arranged in the blood component separator and is used for filtering the plasma to obtain the platelet; the second storage bag is communicated with the blood component separator and is used for storing the filtered remained plasma; the third filtering mechanism is positioned under the second filtering mechanism. The invention also discloses a blood component separation method. The blood component separation method has the steps that under the gravity action, microcapsules are filtered by a microcapsule filter, leukocyte is filtered by a leukocyte filter, and the erythrocyte, the platelet and the plasma are separated by the first filter and the second filter. The device has the advantages that the cost is low, and the operation is easy.

Description

Technical field [0001] The invention relates to a blood component separation device and a blood component separation method. Background technique [0002] The scientific and rational use of blood is one of the four major strategies of the World Health Organization for safe blood transfusion, and its core content is component blood transfusion. Basically, the preparation of blood components adopts mechanical centrifugation and then uses a slurry clamp or a blood component separator to separate red blood cells and plasma. Its advantages are simple, rapid and batch operation. However, the current method has the following shortcomings: [0003] The quality of the prepared blood components is greatly affected by the centrifugation parameters (speed, temperature, time, acceleration, deceleration). For example, when the centrifugal force is 3840g and centrifugation for 12 minutes, the hematocrit value is 0.47±0.03; when the centrifugal force is 2475g and centrifugation for 10 minutes, t...

AI Technical Summary

Problems solved by technology

[0007] The cost of blood component preparation is high: it requires resources such as equipment (centrifuge / component separator), manpower (professional technicians), electricity, etc.

[0008] A clean operating space is required, and it is not suitable for field (wartime, disaster relief, anti-terrorism) and blood collection vehicles
