Problems solved by technology

However, the currently prepared PRF is mainly in the form of fibrous clots. This form of PRF is not conducive to combining with other biological materials, which limits its clinical application, and there will be problems of blood contamination during the preparation process.

Abstract

The invention relates to a device for preparing injection type autologous i-PRF and a preparation method. The device comprises a centrifugal tube which can be placed in a centrifugal machine for centrifugation and is of a barrel-shaped structure, and a tube opening of the centrifugal tube is in sealed connection with a protective cover capable of allowing an injection needle to penetrate through;an axial opening is formed in the side wall of the centrifugal tube in the axial direction, and a puncturable membrane which is used for sealing the axial opening and can be punctured is connected tothe axial opening in a sealed mode; and a sliding block sliding in the axial opening is further arranged on the side wall of the centrifugal tube in a sliding mode, and a through hole corresponding tothe axial opening is formed in the sliding block. Meanwhile, the invention also discloses the i-PRF prepared by using the device through blood sampling, low-speed centrifugation, extraction and uniform mixing. The device is simple in structure and convenient to operate, the probability of blood pollution is reduced, and the prepared product is in a liquid state with fluidity, is convenient to useand is also beneficial to promoting tissue healing and regeneration.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to a device and a preparation method for preparing injection-type autologous i-PRF. Background technique [0002] Autologous platelet-rich plasma (PRP) was first proposed in the 1970s and became widely used in the 1980s. Due to the addition of anticoagulant components that can cause immune rejection and are not easy to operate, in order to continue the advantages of PRP and avoid the above shortcomings, Choukroun prepared the second-generation platelet concentrate in France in 2001, called platelet-rich fibrin ( PRF) is a fibrin clot rich in platelets obtained by one centrifugation of autologous venous blood without added anticoagulant. From the perspective of ultrastructure, it is found that the different conformation of fibrin network structure is the main structural feature that distinguishes the two, and they also have obvious differences in density and type. The density of fibrin i...
