A medical hematopoietic stem cell collection instrument

Abstract

The invention belongs to the technical field of medical devices, specifically a medical hematopoietic stem cell collection instrument, including an installation body, a blood collection unit, a stem cell separation unit, a stem cell collection tank, a plasma collection tank, a pressurized pump, a negative pressure pump, a heparin bottle, The plasma conveying tube and the ice cube storage box, the blood collection unit is connected with the stem cell separation unit; the stem cell separation unit is connected with the stem cell collection tank; the stem cell separation unit is also connected with the plasma separation tank; the booster pump is connected with the plasma collection tank; The pressure pump is connected to the stem cell collection tank; the heparin bottle is connected to the stem cell separation unit; one end of the plasma delivery tube is connected to the blood collection unit, and the other end of the plasma delivery tube is connected to the plasma collection tank; the plasma delivery tube is also provided with a normal saline introduction tube; The invention can improve the purification precision of stem cell collection under the continuous working state.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a medical hematopoietic stem cell collection instrument. Background technique [0002] Hematopoietic stem cells are generally derived from stem cells in bone marrow, peripheral blood, umbilical cord blood, and placenta. Hematopoietic stem cells have the ability to self-renew and can differentiate into various blood cell precursor cells, and finally generate various blood cell components, including red blood cells, white blood cells, and platelets. Can also differentiate into various other cells. They have good ability to differentiate and proliferate, so they are widely used in the treatment of malignant hematological diseases, severe aplastic anemia, some solid tumors, some abnormal immune diseases, some genetic diseases, metabolic diseases and very severe bone marrow type acute radiation sickness . At the same time, hematopoietic stem cell transplantation is also an...

Problems solved by technology

Although this technical solution can solve some disadvantages of the blood collection method of negative pressure generated by artificial pulling, if the negative pressure pump is used to directly collect blood from the human body, the blood collection method is not gentle. This stem cell collection device also uses centrifugation to process the collected blood. blood, but this stem cell collection device does not clean up the plasma other than stem cells, so that the purity of the obtained stem cells is actually not high. When the blood is in a state of differential centrifugation, if no external pressure is applied, the purified stem cells will not Easy to collect, if the time spent in the separation chamber is too long, the stem cells will be easily broken by centrifugation; at the same time, because the plasma other than stem cells is not processed, the plasma in the stem cell collection device will accumulate, resulting in the stem cell collection device cannot work continuously
