Plasma collecting device adopting centrifugal separation method

Abstract

The invention discloses a plasma collecting device adopting a centrifugal separation method and relates to the field of medical instruments. The device comprises a centrifuge, a centrifuge bin arranged at the first half part of the centrifuge and a control circuit arranged in the centrifuge, wherein a centrifugal cup, a plasma layer and a blood cell layer which are connected sequentially from inside to outside in a wrapping manner are arranged in the centrifuge bin, the centrifugal cup is connected with a centrifugal cup blood feeding pipe, the plasma layer is connected with a centrifugal cup plasma discharging pipe, a blood cell detector is arranged in the middle of the centrifugal cup plasma discharging pipe, the other end of the centrifugal cup plasma discharging pipe is connected with a plasma collecting bag, a bowl photoelectric sensor is fixed on the inner wall of the centrifuge bin and located in front of the blood cell detector, the control circuit consists of a control module, a debugging module and an alarming module, and the alarming module is connected with the control module and the alarming module and electrically drives and controls an audible and visual alarm. Modular and multi-channel design is adopted, the system response time is short, processing of abnormal information is timely, and the function is advanced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a centrifugal separation plasma collection device. Background technique [0002] Plasma is an important component of human blood, and it is also an important raw material for some blood products, such as: human albumin, human placental albumin, human immunoglobulin for intravenous injection, human immunoglobulin for intramuscular injection, human histamine Immunoglobulin, specific immunoglobulin, hepatitis B immunoglobulin, rabies immunoglobulin, tetanus immunoglobulin, human coagulation factor VIII, human prothrombin complex, human fibrinogen, anti-human lymphocyte immunity Blood products such as globulin. [0003] According to relevant regulations and requirements, the collected raw plasma should not be mixed with excessive blood cell components, including: platelets, white blood cells, red blood cells and other formed components. In order to extract plasma components from bloo...
