Description

[0001] This utility model claims the priority of a Chinese patent application titled "A Low-temperature Centrifugal Refrigeration Device for Medical Clinical Treatment" with the application number 202321930629.7 and filed on July 21, 2023. The content of the above Chinese patent application is hereby incorporated into this application by reference. Technical Field

[0002] This utility model relates to the technical field of medical devices, and particularly to a centrifugal device for PRP preparation. Background Art

[0003] Platelet-rich plasma (PRP), platelet-poor plasma (PPP), and platelet-rich fibrin (PRF) are all extracted from blood. Among them, PRP is highly concentrated platelets and rich in various growth factors. It can promote cell proliferation and differentiation, and PRP has been gradually applied to tissue repair in the fields of stomatology, plastic surgery, orthopedics, otolaryngology, neurosurgery, etc.

[0004] Since PRP is easily activated at room temperature, coagulates quickly and is prone to deterioration, most of the existing PRP preparations are obtained by centrifugation after adding anticoagulants to venous blood at room temperature. However, adding anticoagulants to blood will destroy the physical and chemical properties of blood components, resulting in certain side effects of the injected PRP and thus reducing the use effect of PRP.

[0029] In order to better explain the present utility model for easy understanding, the present utility model will be described in detail below in conjunction with the accompanying drawings through specific embodiments.

[0030] As Figure 1 shown, this embodiment provides a centrifugation device for PRP preparation. The centrifugation device includes a refrigeration device 1, a centrifugation device 2, and a secondary cooling module (not shown). Among them, the refrigeration device 1 includes a box body 11, a cover body 12, and a main cooling module. The cover body 12 covers the box body 11.

The main cooling module is used to cool the first cooling space 13 and the second cooling space 14. The centrifugation device 2 is disposed in the first cooling space 13. The first cooling space 13 provides a low-temperature environment for the centrifugation device 2. The secondary cooling module is disposed in the second cooling space 14 to maintain the low-temperature environment of the centrifugation device 2 in the adjacent first cooling space 13. The centrifugation device 2 is used to centrifuge the blood reagent tubes placed therein to form PRP.

[0031] The centrifugation device for PRP preparation in this embodiment, due to including the refrigeration device 1, the centrifugation device 2, and the secondary cooling module, by forming adjacent first cooling space 13 and second cooling space 14 inside the refrigeration device 1, where the first cooling space 13 provides a low-temperature environment for the centrifugation device 2. Through the combination of the refrigeration device 1 and the centrifugation device 2, the PRP prepared by the centrifugation device 2 can be kept at a low temperature to avoid the coagulation and deterioration of PRP and avoid the use of anticoagulants, improving the use effect of PRP. At the same time, since the secondary cooling module is disposed in the second cooling space 14 adjacent to the first cooling space 13, when the cover body 12 of the centrifugation device is opened and closed multiple times to take blood, the temperature rise in the first cooling space 13 is avoided, further ensuring the low-temperature environment in the first cooling space 13. And this low-speed low-temperature centrifuge only needs to open the cover body 12 and put the blood reagent tubes into the centrifugation device 2, which is simple and convenient to operate and is convenient for clinical application.

[0032] A storage rack (not shown) is also provided in the second cooling space 14. The storage rack is used to place the centrifuged blood reagent tubes, that is, the PRP reagent tubes, for convenient storage of PRP.
