Technical Field
The utility model relates to the field of medical supplies, in particular to a platelet-rich plasma separation and collection bag.
Background
Platelet-rich plasma (PRP) is a platelet concentrate extracted from autologous blood by centrifugation. The platelet-rich plasma can promote the repair of bones and soft tissues, is self-originated, and has the characteristics of no immunological rejection and small damage to organisms. For more than twenty years, platelet rich plasma has been used in a variety of disciplines such as orthopedics, oromaxillofacial surgery, cardiothoracic surgery, neurosurgery, obstetrics and gynecology, ophthalmology, otorhinolaryngology, general surgery, and plastic cosmetology. The principle of preparing the platelet-rich plasma is as follows: platelets are extracted by centrifugation, depending on the sedimentation coefficients of the various components in the whole blood. In the process of centrifuging, because the sedimentation speed of red blood cells is the fastest, the blood enters the bottom of the test tube after centrifugation, and the supernatant is at the uppermost layer, namely the middle layer of the platelet. The red blood cells and a part of the supernatant are removed, and the remainder is the platelet rich plasma. The removed supernatant is called platelet-poor plasma (PPP). The quality of the platelet rich plasma extraction is a key factor affecting its function and effectiveness.
At present, most of the separation operations of the platelet-rich plasma are still performed by placing a plurality of centrifuge tubes in an open space, and the operation mode is easy to cause pollution, thereby reducing the extraction quality of the platelet-rich plasma.
