Abstract

The invention relates to the field of mechanical technology, in particular to a simple autologous blood recovery device, which includes a recovery device. One side of the recovery device is provided with a recovery cover and a recovery box. The recovery device includes a blood bag and several recovery tubes below it, one of which recovers The middle section of the tube is equipped with a blood ultrafilter, the bottom of several recovery tubes is equipped with an artificial heart-lung machine pump head, the top of the recovery cover is provided with a handle, the inner side of the top of the recovery cover is provided with a hanging plate, and the inner side of the bottom end of the recovery cover is symmetrical An arc plate is arranged, and a groove is provided on the top surface of the front end of the recycling box. The blood of the present invention is pumped through the pump head of the artificial heart-lung machine, so that the blood passes through the ultrafiltration of the blood ultrafilter, and the excess metabolites and water are separated, and the ultrafiltered blood is returned to the blood bag, so that the circulating ultrafiltration, Finally, the blood reaches or approaches the original level of the patient; by assembling the recovery device on the recovery cover, and closing the recovery cover with the recovery box, it is easy to carry.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a simple autologous blood recovery device. Background technique [0002] The blood recovery in the prior art is through the pumping of the pump head of the artificial heart-lung machine, and the blood diluted in the patient's operation is pumped to the ultrafiltration of the blood ultrafilter, and the excess metabolites and water are separated, so that the blood reaches or close to the patient's preoperative level. Among them, the pump head of the artificial heart-lung machine is an essential equipment in hospitals that carry out cardiothoracic surgery and extracorporeal circulation operations. At present, special blood salvage machines are used at home and abroad to recover blood. Blood salvage machines are expensive. Each machine is about 400,000 yuan, and the price of supporting consumables is also about 3,000 yuan. This brings a large economic burden to hospitals and pat...
