Description

PRP kit with detachable inner and outer tube {Detachable Platelet Rich Plasma Kit}

The present invention relates to a PRP kit equipped with a detachable inner and outer tube, and more particularly, a detachable inner and outer tube in which the inner tube is separated into an upper inner tube, a lower inner tube, and a central receiving tube so that PRP can be easily extracted from blood. It relates to the provided PRP kit.

Blood is divided into plasma and blood cells, and the plasma is rich in platelets. PRP is platelet-rich plasma (PRP), which is a concentrate obtained by selectively extracting the platelet portion from autologous blood. Platelets included in PRP induce skin regeneration by directly inducing regeneration of damaged skin tissue due to various growth factors.

PRP kits are widely used for procedures using platelet-enriched plasma obtained by collecting blood to produce platelet-rich plasma and then using a centrifuge to obtain platelet-enriched plasma.

In addition, the inner periphery of the central outer pipe (1b) is provided with a connecting pipe support plate (1b') extending inwardly to support the outer periphery of the upper capillary connecting pipe (31), thereby disengaging the upper inner pipe (10). When the central receiving tube 30 is separated from the lower inner tube 20 can be prevented.

Looking at the action of the PRP kit having a detachable inner and outer cover according to the present invention having the above configuration is as follows.

As shown in FIGS. 2 to 6, in the PRP kit equipped with a separable inner and outer tube of the present invention, the inner tube 2 is composed of an upper inner tube 10, a lower inner tube 20 and a central receiving tube 30, The exterior 1 is composed of an upper exterior 1a, a central exterior 1b, and a lower exterior 1c to correspond to the configuration of the inner tube 2, so that the upper exterior 1a is rotated to form the central exterior 1b. ) When the coupling is released, the upper inner tube 10 in close contact with the inner periphery of the upper outer tube 1a is released from the central receiving tube 30. At this time, the connecting pipe support plate 1b' provided in the central outer pipe 1b is in close contact with the upper capillary connecting pipe 31 of the central receiving pipe 30, so that the central receiving pipe 30 is attached to the lower inner pipe 20. ) to prevent dissociation.

In addition, the upper cover 40 and the lower cover 50 provided on the inner tube 2 are lifted up and down from the inner periphery of the upper inner tube 10 and the lower inner tube 20 by the upper gripping part 42 and the lower part. By holding and then rotating the gripper 52, it is possible to finely adjust the internal pressure of the upper inner tube 10 and the lower inner tube 20, which is controlled so that the PRP is accurately positioned in the central receiving tube 30. When the upper inner tube 10 and the lower inner tube 20 are disengaged, PRP (platelet-rich plasma) accommodated in the central receptor tube 30 can be easily obtained by adjusting the position of the PRP.

On the other hand, after inserting the syringe (S) into the inner periphery of the upper capillary conduit 31 of the central accommodating tube 20 where the coupling with the upper inner tube 10 is released, the PRP kit is switched in the up-and-down direction so that the lower By rotating the exterior (1c), the lower inner tube (20) can be separated from the central accommodation tube (30), and the PRP accommodated in the central accommodation tube (30) seals the central accommodation tube (30). Then refrigerate and use as needed.

In this way, the PRP kit equipped with the separable inner and outer tubes of the present invention is provided so that the outer tube 1 and the inner tube 2 are separated into three stages, so that only the PRP contained in the central receptor tube 30 can be accurately extracted from the blood. do.

The present invention is not limited to the specific preferred embodiments described above, and various modifications can be made by anyone having ordinary knowledge in the art to which the present invention belongs without departing from the gist of the present invention claimed in the claims. Of course, such changes are within the scope of the claims.
