Description
Technical field
The utility model relates to blood collection device technical fields, fill more particularly, to a kind of blood bag fixation device and blood sampling
It sets.
Background technique
Cord blood is to remain in the blood in placenta and umbilical cord after delivery of baby, ligature of the cord and detachment, usually discarded
It is unused.Containing a large amount of stem cell in Cord blood, stem cell is the seed of life, it can break up the various cells of adult body,
Bear a variety of different fruits --- blood cell, nerve cell, bone cells etc..With the prosperity of science and technology, medical expert
The method for treating disease is developed using the stem cell in Cord blood.Stem cell is with self-renewing, hyperproliferation and more
The cell colony of item differentiation potential.These cells can maintain the characteristic and quantity of own cells by division, and can be further
Be divided into various histocytes, thus in terms of play a positive role.Medical research discovery in the late three decades,
Contain candidate stem cell (HSC) very rich in Cord blood, human body hematopoiesis and immune system can be rebuild, can be used for Hematopoietic Stem
Cell transplantation, treatment hematological system, immune system and hereditary metabolic disorders and congenital disorders.Therefore, Cord blood, which has become, makes
The important sources of hemocytoblast, have been widely used in clinic, are valuable human biological's resources.
Cord blood collection blood bag is that bleeding of the umbilicus saves one of series of products, is mainly used for acquisition, the separation of Cord blood.Cord blood collection
Blood bag is that bleeding of the umbilicus saves one of series of products, is mainly used for acquisition, the separation of Cord blood.One cord blood can only generally be collected
100ml or so, after Cord blood is separated, upper layer is blood plasma, and middle layer is tunica albuginea layer, and lower layer is red blood cell, and navel blood stem cell is rich
It is contained in tunica albuginea layer, only 20-30ml.Currently, cord blood collection blood bag is generally the rectangle blood bag of standard.
In the prior art, blood taking bag is needed when separating to plasma component, red blood cell component and candidate stem cell component
It is centrifuged, and needs to be separated at least twice, it could be by plasma component, red blood cell component and candidate stem cell
Component completes separation, and such lock out operation is more troublesome.And during the separation process, due to gravity, inside blood taking bag
Blood can reduce the settling height of red blood cell, so that Hematopoietic Stem is thin because the reason of acceleration of gravity collapse downwards
Born of the same parents cannot be sufficiently separated with red blood cell, and the ratio that red blood cell accounts in the candidate stem cell after separation is higher.
The information disclosed in the background technology section is intended only to deepen the reason to the general background technology of the utility model
Solution, and it is known to those skilled in the art existing to be not construed as recognizing or imply that the information is constituted in any form
Technology.
