Problems solved by technology

Although this separation method solves the above problems, since the plasma pipeline needs to form centrifugal motion at the same time, the difference in centrifugal force will cause the plasma pipeline to be easily entangled and worn, which will easily lead to damage to the plasma pipeline and cause PRP products to be damaged. Pollution and unusable problems occur

Abstract

The invention belongs to the technical field of medical instruments, and discloses a plasma separation device and a centrifugal machine applying the same. The plasma separation device comprises a separation cup which is constructed to be an airtight container and installed on a rotary disc of the centrifugal machine in a horizontal mode; The plasma separation device further comprises a plasma pipeline which communicates with the left end and the right end of the separation cup, wherein the plasma pipeline is made of a rubber material, and the rubber material is constructed as follows: the abrasion loss is less than 100mg, the tearing strength is greater than 45N, and the Shore hardness range is 50-100, so that the plasma pipeline can automatically rebound after distortion. The plasma separation device is capable of prolonging the service life of the plasma pipeline while reducing the manual operation, simplifying a PRP preparation process, and reducing the risk that a PRP product is polluted.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a plasma separation device and a centrifuge using the device. Background technique [0002] Platelet rich plasma (Platelet rich plasma, referred to as PRP) is a platelet concentrate extracted from autologous venous blood by density gradient centrifugation, containing high concentrations of platelets, white blood cells and fibrin. Because PRP is derived from autologous body, has no immune rejection, is simple to make, and has little damage to the body, it has been used in many disciplines in recent years, such as orthopedics, cardiothoracic surgery, neurosurgery, obstetrics and gynecology, ophthalmology, otolaryngology, and general surgery. and Plastic Surgery etc. Especially in many European and American countries, PRP is widely used. Usually, the extraction of platelet concentrate from autologous blood by centrifugation is to input the plasma into the plasm...
