Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a PRP sealing structure. Background Technology

[0002] Currently, autologous platelet-rich plasma (PRP) is increasingly widely used in clinical applications in orthopedics, dentistry, and other fields. With the continuous advancement of medical technology, the need for tissue repair and regeneration is becoming increasingly urgent. PRP, obtained by centrifuging whole blood to obtain high concentrations of platelets, can play a crucial role in promoting tissue repair and regeneration, highlighting its clinical value and attracting growing attention. Its expanding application scope has brought new hope and better recovery outcomes to many patients. However, existing PRP preparation technologies still have many shortcomings in practical applications, limiting its further development and promotion.

[0003] In existing technologies, PRP preparation typically employs a combination of ordinary centrifuge tubes and syringes, or a dedicated PRP preparation kit. The ordinary centrifuge tube and syringe combination is less expensive and relatively simple to operate, making it widely used in some basic medical settings. It utilizes ordinary centrifuge tubes for blood centrifugation, followed by PRP extraction and transfer using a syringe. Dedicated PRP preparation kits, on the other hand, are more professionally designed, offer better sealing, and some kits even possess specific structures and functions that can improve the quality and efficiency of PRP preparation to a certain extent. They achieve blood centrifugation and PRP collection through specially designed components and processes.

[0004] Existing technologies have significant drawbacks. Traditional PRP preparation methods lack sufficient sealing, which can easily lead to blood leakage or contamination, affecting not only the quality of the PRP but also potentially posing a threat to the patient's health. Furthermore, the cumbersome procedures increase the workload of medical staff and reduce work efficiency. Moreover, PRP is easily exposed to open environments during transfer, increasing the risk of infection. In addition, unstable centrifugation efficiency and platelet recovery rates make it difficult to guarantee PRP quality and meet the high standards required for clinical treatment.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] This utility model discloses a PRP sealing structure, such as Figure 1 and Figure 3 As shown, it includes a centrifuge tube 1 and a syringe 2. The centrifuge tube 1 and syringe 2 are nested to form a sealed structure. The centrifuge tube 1 and syringe 2 are connected by nesting to form a closed system, which can effectively prevent PRP from contacting the external environment and prevent it from being contaminated. At the same time, the core rod of syringe 2 can move up and down to realize the extraction and transfer of PRP. The end of centrifuge tube 1 is provided with a gray plug 3 for sealing the preparation device, ensuring the airtightness of the entire preparation process.

[0022] Specifically, centrifuge tube 1 includes components such as the tube body and the sealing outer tube 4. The tube body is a center-end type, made of polypropylene material. Polypropylene material has good chemical stability and corrosion resistance, ensuring that centrifuge tube 1 will not chemically react with PRP during use, thus affecting its quality. The sealing outer tube 4 is provided at the end of the tube body. The sealing outer tube 4 has internal threads for threaded connection with other components. The sealing outer tube 4 can also be replaced by some rubber sleeves with sealing properties, as long as the sealing performance of the connection can be guaranteed.

[0023] The gray plug 3 at the end of centrifuge tube 1 includes a plug body and a sealing inner tube 5. The sealing inner tube 5 has external threads and is threadedly connected to the sealing outer tube 4 of centrifuge tube 1, thus sealing the end of centrifuge tube 1. This threaded connection of the sealing inner tube 5 provides a good seal, preventing external contaminants from entering. A positioning groove is provided in the middle of the sealing inner tube 5, and a positioning tube 6 is provided in the middle of the sealing outer tube 4 of centrifuge tube 1. The positioning tube 6 interlocks with the positioning groove. This positioning structure ensures accurate connection between the gray plug 3 and centrifuge tube 1, further improving the sealing performance.

[0024] Specifically, the syringe 2 includes components such as a syringe barrel and a plunger. The syringe barrel is also of the mid-head type and is made of polypropylene material to ensure its chemical stability. A sliding sleeve 7 is provided on the outside of the syringe barrel, and the sliding sleeve 7 is set inside the centrifuge tube 1. The sliding sleeve 7 is provided with a sealing inner tube 5 that is the same as the gray plug 3. The end of the syringe barrel is provided with a sealing outer tube 4 that is the same as the end of the centrifuge tube 1. The syringe 2 and the sliding sleeve 7 are connected to each other by threads through the sealing outer tube 4 and the sealing inner tube 5, so that the syringe 2 and the sliding sleeve 7 are tightly connected and can slide relative to each other inside the centrifuge tube 1.

[0025] A sealing gasket 8 is provided at the end of the sliding sleeve 7, and a raised structure is provided on the sealing gasket 8. A limiting protrusion is provided inside the centrifuge tube 1 to limit the sliding sleeve 7 and prevent it from sliding excessively. The sealing gasket 8 further enhances the sealing performance, and the raised structure increases the friction with the inner wall of the centrifuge tube 1, improving the sealing effect. The sliding sleeve 7 can be removed from the centrifuge tube 1 under force. A through hole is provided in the middle of the sealing gasket 8, and a protrusion is also provided at the end of the sliding sleeve 7. The protrusion passes through the through hole and connects with it. This connection method ensures that the sealing gasket 8 and the sliding sleeve 7 are firmly connected. The end of the sliding sleeve 7 is provided with external threads, and the sealing gasket 8 is provided with internal threads. The sliding sleeve 7 and the sealing gasket 8 are threaded together, making the connection tight and not easy to loosen.

[0026] The implementation principle of this embodiment is as follows: The PRP sealing structure of this embodiment forms a closed system through the nested connection of centrifuge tube 1 and syringe 2, effectively solving the problem of poor sealing in traditional PRP preparation devices and avoiding blood leakage and contamination. Simultaneously, the movable design of the syringe 2 core makes PRP extraction and transfer operations more convenient, achieving closed transfer of PRP and reducing the risk of infection. The use of polypropylene material ensures the chemical stability and corrosion resistance of the device, and the mid-head structure design improves the adaptability and operational efficiency of the device, increasing work efficiency and making platelet enrichment and recovery rates more stable, ensuring the quality of PRP. Compared with existing technologies, this represents a significant improvement and enhancement.
