Description

Technical Field

[0001] The invention relates to the technical field of autologous blood recovery machines, and specifically relates to an autologous blood recovery transition storage box. Background Art

[0002] The blood recovery machine uses a negative pressure absorption device to collect traumatic bleeding or intraoperative bleeding into a blood reservoir, mixes it with an appropriate amount of anticoagulant during the suction process, and then uses a high-speed centrifugal blood recovery tank to separate the cells after multi-layer filtration. The waste liquid, broken cells and harmful components are diverted to the waste liquid bag, and the blood cells are washed, purified and concentrated with saline. Finally, the pure and concentrated blood cells are stored in a blood bag and returned to the patient.

[0003] In current clinical practice, due to the uncertainty of the amount of bleeding in surgical patients, in order to improve the safety of surgery, an autologous blood recovery machine is usually used during surgery. Regardless of the amount of bleeding during the surgery, the patient's autologous blood is directly transported to the blood recovery machine for processing. Blood recovery machines are mostly disposable consumables and are expensive. If the patient's surgical bleeding is small and the conditions for autologous blood recovery are not met, and a blood recovery machine is used directly, it will cause a waste of medical resources for the blood recovery machine.
