Device and method for separating small-capacity blood components

Abstract

The invention discloses a device and method for separating small-capacity blood components. The device and method aim to solve the problems that currently, domestically voluntary blood donation blood components are mainly separated in a manual work mode, in the mode, the purity of the blood components acquired through separation is low, blood resources are severely wasted, labor and time are wasted, efficiency is extremely low, and blood can be further wasted due to breakage of blood bags. The device comprises a machine hemostix, a first pipeline, a first three-way connector, a combination pump clamp, a second pipeline, an anticoagulant adding device and the like, wherein the first pipeline is connected with the machine hemostix, and the second pipeline is arranged on the combination pump clamp. When the device is used for voluntary blood donation (300ml to 400ml), rapid blood collection can be achieved and the blood components of whole blood can be separated immediately, and the multiple blood components can be gathered, separated and collected at one time. In the process of use, the whole blood can be automatically gathered only through a blood collection point or a blood collection vehicle, the device is used for separating and collecting the blood components, and eventually collection bags filled with the blood components are taken down.

Description

technical field [0001] The invention relates to the field of medical instruments, especially the field of medical instruments for blood collection, in particular to a small-capacity blood component separation device and a separation method thereof. The device of the present invention can replace the manual method of collecting whole blood with blood bags used in the current voluntary blood donation (300ml-400ml) in blood banks at home and abroad, and can realize automatic collection, separation, and collection of various blood components, and has the advantages of fast, accurate, simple, and painless Pollution, high purity of blood component separation, etc. Background technique [0002] At present, the separation of blood components for voluntary blood donation in China mainly relies on manual work. The separation process is as follows: medical personnel first collect whole blood through blood collection points or blood collection vehicles, and store the whole blood compon...
