Umbilical cord blood separation device capable of preventing centrifugal dropping and folding of blood bags

Abstract

The invention discloses an umbilical cord blood separation device capable of preventing centrifugal dropping and folding of blood bags. The umbilical cord blood separation device comprises an umbilical cord blood separation device body. The umbilical cord blood separation device body comprises a pearl wool foam plate, and double blood bags including a large blood bag and a small blood bag. A connection pipe is arranged between the large blood bag and the small blood bag. The pearl wool foam plate is arranged on the upper middle portion of the large blood bag. Upper support plates and lower support plates are arranged on the pearl wool foam plate. The upper support plates include a first support plate and a second support plate. The lower support plates include a third support plate and a fourth support plate. A clamping space is formed between the upper support plates and the lower support plates. The umbilical cord blood separation device has the advantages that the device has a certain support hardness relative to sponge foam blocks, and dropping and folding in a centrifugation process are avoided to ensure the cell layering effect; the device has high elasticity and a strong anti-vibration effect and is often applied to various transportation protections, avoiding cell layering turbidity caused by vibration generated in a braking process of a centrifugal machine; the devicehas good adsorption property, and if the blood bags are broken, blood can be sucked in time to avoid splash contamination.

Description

technical field [0001] This technology is applied to centrifugation and concentration of umbilical cord blood hematopoietic stem cells. As a centrifugal separator, this product can improve the preparation efficiency, reduce the impact on cord blood cell viability, improve the quality of cord blood preparation, and provide a new solution to the common problems encountered in blood preparation. Background technique [0002] The use of blood collection bags to prepare blood components has gradually become popular in our country. Cord blood is a source of hematopoietic stem cells, most of which are red blood cells. When establishing a cord blood bank, in order to reduce the volume of cryopreservation, it is necessary to remove a large number of red blood cells by centrifugation and only preserve nucleated cells rich in hematopoietic stem cells. At present, the blood bag is usually placed in the centrifuge cup of the centrifuge for centrifugation and concentration, but the phen...

AI Technical Summary

Problems solved by technology

We have found in actual work that the use of sponge foam blocks cannot play a supporting role in the blood bag, resulting in an unsatisfactory recovery rate of nucleated cells from umbilical cord blood

For large-volume umbilical cord blood, plastic double bags are used to clamp or water bags are placed in the centrifuge cup, which will cause extrusion, resulting in unclear boundaries between plasma, buffy coat, and red blood cells after centrifugation, which will affect the collection of nucleated cells.
