Abstract

The invention discloses an efficient blood recycler which comprises a pressure adjuster, a suction tube, a rough blood filter, a fine blood filter and a blood bag, wherein the suction tube is connected with a blood inlet at the top of the rough blood filter; the pressure adjuster is connected with the top of the rough blood filter; the bottom of the rough blood filter is connected with a blood collector through a blood transfusion tube with a valve a; the blood collector is connected with the fine blood filter; the fine blood filter is provided with a liquid outlet connected with the blood bag and a draining port connected with an effluent box; a branch which is connected with an anticoagulant bottle filled with anticoagulant is arranged on the suction tube; a flow meter is arranged between the branch and the rough blood filter. The invention aims to provide the efficient blood recycler which is used for multilevel filtering the recycled blood, has a simple and reliable structure, can quickly remove effluent from the blood and can break cells and harmful components.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a high-efficiency blood recovery machine. Background technique [0002] Blood salvage can reduce the loss of blood of patients, reduce the use of blood in blood banks, and reduce the medical expenses of patients. The blood recovery machine collects traumatic bleeding or intraoperative bleeding into the blood storage device through a negative pressure absorption device. After multi-layer filtration, the waste liquid, broken cells and harmful components are shunted into the waste liquid, and the blood cells are treated with normal saline. Cleaning, purification and concentration are carried out, and the pure and concentrated blood cells are stored in the blood bag and returned to the patient. [0003] Most of the existing blood salvage machines are cleaning type blood salvage machines, but the equipment of the cleaning type blood salvage machines is expensive and the operation is ...
