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.

specific Embodiment 1

[0029] see figure 1 , figure 2 It can be seen that the present invention is a umbilical cord blood separation device that prevents the blood bag from falling down centrifugally and folds, including the umbilical cord blood separation device body; The two blood bags are a large blood bag and a small blood bag respectively, a connecting pipe is arranged between the large blood bag and the small blood bag, the pearl cotton foam board is arranged in the middle and upper part of the large blood bag, and the pearl foam There is an enhanced friction structure on the board. The pearl cotton foam board is provided with an upper support plate and a lower support plate. There is a clamping space between the upper support plate and the lower support plate. The pearl cotton foam board is rectangular, and the length of the pearl foam board is 15cm, the height of the pearl cotton foam board is 11cm, the pearl cotton foam board is set in the middle and upper part of the big blood bag, the p...

specific Embodiment 2

[0031] A method for using a umbilical cord blood separation device with a blood-proof bag centrifugally falling and folding, characterized in that:

[0032] Step 1: Place the pearl foam board, place the pearl cotton foam board between the two blood bags, the big blood bag passes through one side of the pearl cotton foam board or in the clamping space, and place the pearl cotton foam board on the upper part of the big blood bag 2 -3cm;

[0033] Step 2: The pearl foam board acts as a centrifugal partition. Place the two blood bags and the pearl foam board in the centrifugal adapter. Place the blood bag on the side that needs to be grouted close to the pearl foam board. The big blood bag is labeled One side is in close contact with the pearl foam board;

[0034] Step 3: Place the small blood bag, place the small blood bag above the large blood bag, and press the label surface of the small blood bag against the upper 2-3cm of the blood bag;

[0035] Step 4: Take out the two blood ...

specific Embodiment 3

[0037] see figure 1 , figure 2 It can be seen that the pearl cotton foam board 1 is placed between the two bags, and the blood bag on the side that needs to be grouted is placed close to the centrifugal separator 10. The side of the blood bag with the label is in close contact with the foam cotton to increase friction. Prevent the blood bag from sliding down. Pass the upper 2cm of the blood bag around the foam board and press it with another blood bag, such as figure 2 shown. After centrifugation, take out the centrifugal adapter 11 slowly, grab the blood bag connecting tube 8, and slowly pull out the blood bag that has sunk in the centrifugation, so that the layering effect can be clearly defined. Foam pearl cotton as a blood bag support has the following advantages: 1) Foam pearl cotton is easy to obtain, no other production is required, just cut to a suitable size; 2) Foam pearl cotton has a certain strength compared to sponge foam blocks. Supporting hardness, it will ...

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...
