Abstract

The invention discloses a device for collecting and reusing red blood cells, which includes a negative pressure device and a processing device. The negative pressure device includes a first housing, a vacuum pump and a liquid injection tube. A plurality of flexible tubes are arranged in the first housing. The processing device includes The second housing and the separate washing device with the third housing, the third housing is provided with a first orifice plate and a second orifice plate, the first orifice plate and the second orifice plate divide the third housing into a washing area and the protective agent storage area, the third housing is provided with a third orifice, the first hose is located in the second housing, the second hose is located in the washing area, the third hose is located in the protective agent storage area, and the washing A fourth hose and a fifth hose are respectively provided in the area and the protective agent storage area, and the fourth hose and the fifth hose are respectively connected to a detergent storage and a protective agent storage, and a Y-shaped pipe is arranged in the second housing. The device can effectively solve the problems of long centrifugation time, small single separation volume and separated cells not meeting utilization requirements.

Description

technical field [0001] The invention belongs to a red blood cell collection device, in particular to a red blood cell collection and reuse device. Background technique [0002] With the improvement of medical level and people's health needs, the demand for clinical blood is also increasing, but at present, there is a problem of insufficient supply of blood sources, which cannot meet the needs of clinical blood; on the other hand, massive intraoperative bleeding has not yet been effectively treated Utilization, resulting in a great waste of blood resources. Although the prior art products can collect and wash intraoperative bleeding, because the prior art basically adopts the step-by-step centrifugation technology of collecting blood and then centrifuging blood cells, resulting in long separation time, damage to the integrity of cells and other adverse consequences, Most of the existing blood separation devices are centrifuges, which are large in size and complex in structur...
