The invention discloses blood component single sampling equipment capable of monitoring in real time in the field of blood treatment equipment. The equipment comprises a blood sampling module, a centrifugal separation module, a component collection module and an anticoagulant conveying module, and further integrates a multi-dimensional real-time monitoring system and a closed-loop self-adaptive regulation and control module. The multi-dimensional real-time monitoring system comprises an online micro-fluidic component detection unit, a physiological parameter monitoring unit and an equipment operation monitoring unit, can realize real-time online detection of blood component purity, cell activity and pollutant residue in the separation process, and synchronously monitors circulation physiological parameters of a blood donor and an equipment operation state at the same time; the closed-loop self-adaptive regulation and control module can dynamically adjust parameters such as the centrifugal rotating speed, the fluid pump speed and the anticoagulant ratio according to real-time monitoring data, and precise closed-loop control over the separation process is achieved. The quality stability of blood single-sampling components can be remarkably improved, meanwhile, the operation risk is greatly reduced, and the method is suitable for clinical blood component single-sampling and preparation scenes.

The invention relates to the field of cell cryopreservation, in particular to a cryopreservation solution combination and a cryopreservation method thereof.The cryopreservation solution combination comprises a cryopreservation solution A and a cryopreservation solution B. The cryopreservation solution A comprises NAD + or precursor molecules thereof or proline; the cryopreservation solution B comprises any one or more of L-carnitine, methyl cellulose, synanthrin, betaine, polyvinyl alcohol (PVA), trehalose or dextran. Meanwhile, the invention provides a cryopreservation method using the cryopreservation liquid combination, the apoptosis phenomenon of cells after resuscitation can be remarkably reduced, the dryness of the cells is maintained, the high activity and high survival rate of the resuscitated cells are ensured, and the cryopreservation liquid combination is particularly suitable for cryopreserved single blood sampling.

The utility model generally relates to the technical field of medical instruments, in particular to a vascular bypass end-side anastomosis deformable supporting device which comprises a main supporting body, an auxiliary supporting body and a connecting piece. The main supporting body is used for being arranged in a receptor blood vessel lumen to expand the vessel wall to assist anastomosis. The auxiliary supporting body is arranged on the main supporting body and used for being placed in a donor blood vessel lumen to expand the vessel wall for end-side anastomosis. The connecting piece is connected to the main supporting body and / or the auxiliary supporting body. The main support body is arranged in the lumen to expand and support the proximal end and the telecentric end of a receptor blood vessel; and expanding and supporting the donor blood vessel through the auxiliary support body, and performing end-side anastomosis. The three-way lumen of a donor blood vessel and a receptor blood vessel is internally supported, anastomotic stoma suturing is completed under supporting, knotting is not performed after two-needle suturing, the supporting body is pulled out from the unknotted opening through the connecting piece, and finally knotting is performed to seal the whole anastomotic stoma. An anastomosis platform with a clear visual field is established for an operator, and the probability of technical errors is reduced.

The utility model relates to the technical field of medical instruments, and discloses a blood matching device convenient for tracing, which comprises a base, a plurality of placing units are arranged on the base, each placing unit comprises a label placing box, a donor sample placing part and a patient blood sample placing part, the donor sample placing part is used for storing donor blood samples and donor blood braids, and the patient blood sample placing part is used for storing patient blood samples. A blood matching card placing part and a blood bag placing part are arranged on the base between the donor sample placing part and the patient blood sample placing part, and the label placing box is fixedly connected to the base. According to the technical scheme, the problems of low working efficiency, high management difficulty, easiness in sample loss and the like caused by scattered storage of samples in the existing blood transfusion department work are solved.

A system and method of transfusing blood from a donor source to a patient. To facilitate the transfusion, a transfer tube is provided. One end of the transfer tube is connected to the donor source and the opposite end is intravenously connected to the patient. A pump assembly is provided that contains a pump and a microprocessor. The transfer tube is engaged with the pump assembly wherein the pump, when activated, acts upon the transfer tube to move blood. The microprocessor monitors the blood volume moved and automatically stops the pump once a predetermined volume of blood has been transferred. If the donor source is a person, the predetermined volume is between 400 milliliters and 450 milliliters. The flow rate of the pump is preferably 100 milliliters per minute.

The present invention provides recombinant antibodies that bind to RhD blood group antigens as well as compositions comprising these recombinant antibodies and methods for selecting combinations of different recombinant antibodies derived from donor blood. The recombinant antibodies are useful in the prevention of neonatal hemolytic disease (HDN), the treatment of idiopathic thrombocytopenic purpura (ITP), and the prevention of anti-RhD alloimmunity in RhD negative patients receiving RhD + transfusion.
