Problems solved by technology

[0004] The centrifuges in the prior art can only realize the stratification of different components in whole blood, and generally rely on the staff to use tools such as pipette guns to realize the transfer and separation of the components of each layer, the workload is heavy, and in the process of pipetting , the centrifuge tube is in an open state, which increases the risk of infection, so the present invention provides a low-cost centrifuge device that can greatly reduce the workload of the staff, and can completely separate the centrifuged layers in a closed environment

Abstract

The invention discloses a blood processing device for a blood transfusion department, which belongs to the technical field of medical equipment. The blood processing device includes a first piston head of a dispensing mechanism arranged in the centrifuge tube; the piston rod is connected to the first piston head, and the tube cover of the centrifuge tube is provided with a through hole for the piston rod to pass through, and the piston rod and the first piston head are connected to each other. The through hole on the tube cover is sealed and connected; the piston driving mechanism is used to drive the first piston head to move up and down; the separation channel is arranged on the tube cover, and the separation channel is provided with a liquid inlet and a liquid outlet; the sealing plug is arranged on The separation channel is used to block and open the liquid inlet and outlet; the plug driving mechanism is used to drive the plug to move along the separation channel; gas device. The blood processing device of the present invention can not only realize the automatic packaging of the separated blood components, but also provide power to multiple mechanisms only through the air-inflating and pumping device, so the cost is lower.

Description

technical field [0001] The invention relates to the technical field of blood processing devices, in particular to a blood processing device for blood transfusion department. Background technique [0002] The Department of Blood Transfusion is responsible for clinical blood transfusion. It is a key department involved in clinical first aid and treatment of critically ill patients. The routine work of the Department of Blood Transfusion includes specimen sampling, blood type identification, pre-transfusion inspection and cross-matching, etc., ensuring clinical safety, effectiveness and scientific blood transfusion . [0003] The blood centrifuge is one of the commonly used blood processing equipment in the blood transfusion department. The two components of plasma or serum cannot be directly separated from the blood, and need to be obtained by centrifugal separation in a blood centrifuge. The centrifugal principle of the centrifuge is based on the different specific gravity o...
