Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PRP tubes, and specifically relates to a self-assembling PRP storage tube. Background Art
[0002] A PRP storage tube, also known as a PRP blood collection tube or a PRP rapid extraction tube, is a blood collection tube used in aesthetic medical projects and is specifically used for extracting and storing platelet-rich plasma. Its main principle is to draw one's own blood and use serum separation gel to extract high-concentration plasma rich in platelets.
[0003] The utility model patent with the authorization announcement number CN215874663U discloses a filtering type PRP extraction tube. The filtering type PRP extraction tube includes an outer tube. A support body is fixedly installed in the inner cavity of the outer tube, and the support body inside the outer tube supports an inner tube. A filtering fiber is embedded in the inner tube, and a filtering device is connected below the filtering fiber in the inner tube. An opening is provided at the middle position of the lower surface of the filtering device. An additive carrier sheet is provided on the upper surface of the filtering fiber. The upper ends of the outer tube and the inner tube are snap-connected with a first butyl rubber stopper, and a second butyl rubber stopper is provided at the lower end of the outer tube. For this filtering type PRP extraction tube, blood penetrates the butyl rubber stopper through a blood collection needle and enters the inner tube. First, it contacts the additive carrier sheet, and then passes through the filtering fiber. Most red blood cells and white blood cells are blocked in the filtering fiber, and a very small number of deformed blood cells are further blocked by the filtering device. The unblocked platelets and plasma enter the lower part of the outer tube from the outlet. Due to the properties of the inner tube, the outer tube, and the filtering material, the pollution and side effects of the blood separation gel are avoided, which is more conducive to the promotion of clinical applications. Using a combination of two butyl rubber stoppers makes it more convenient to extract PRP and easier to perform aseptic operations.
[0004] Although the filtering type PRP extraction tube avoids the pollution and side effects of the blood separation gel, the device still has the following problems in actual use: The butyl rubber stoppers provided at both ends of the PRP extraction tube are only simply inserted and fixed to the outer tube. Although this connection method ensures the sealing performance, the butyl rubber stopper and the outer tube are prone to detachment due to external force in this connection method, thus easily causing contamination and leakage of the sample in the tube body. In view of this, we propose a self-assembling PRP storage tube. Content of the Utility Model
[0005] The purpose of the utility model is to provide a self-assembling PRP storage tube to solve the problems raised in the above background art.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] This embodiment provides a technical solution:
[0027] Please refer to Figures 1-5As shown in the figure, a self-assembled PRP storage tube includes a tube body 1. The upper and lower ends of the tube body 1 are transparent, and butyl rubber stoppers 15 are inserted at the openings at the upper and lower ends of the tube body 1. A fixing seat 11 is fixed at the center of the outer wall of the tube body 1. Two symmetrically arranged grooves 111 are provided inside the fixing seat 11. Through grooves 110 communicating with the grooves 111 are provided at both the upper and lower ends of the fixing seat 11. Sliders 12 are slidably installed in the grooves 111. Clamping blocks 120 are fixed on the arc-shaped inner walls of the sliders 12, and the clamping blocks 120 are tightly bonded to the sliders 12. A threaded rod 13 is rotatably installed at the arc-shaped outer wall of the slider 12. The end of the threaded rod 13 passes through the fixing seat 11 and is threadedly connected to the fixing seat 11. Pressing caps 2 are provided at both the upper and lower ends of the tube body 1. The pressing caps 2 are sleeved outside the butyl rubber stoppers 15 and press the butyl rubber stoppers 15 tightly. Connecting plates 22 are fixed on the two opposite end faces of the two pressing caps 2. The ends of the connecting plates 22 pass through the through grooves 110 and penetrate into the grooves 111. Card slots 220 are provided at the outer wall ends of the connecting plates 22, and the clamping blocks 120 are clamped and matched with the corresponding card slots 220.
[0028] In this embodiment, a through hole 20 is provided at the center of the pressing cap 2, and the overall shape of the through hole 20 is circular. The setting of the through hole 20 facilitates the staff to pass a syringe, etc. through the through hole 20 and the butyl rubber stopper 15 and extract the sample in the tube body 1, which facilitates the operation.
[0029] In this embodiment, two limiting grooves 21 are provided on the circumferential outer wall of the through hole 20. Two symmetrically arranged limiting blocks 151 are provided on the outer wall of the butyl rubber stopper 15, and the limiting grooves 21 are inserted and matched with the limiting blocks 151. This design can realize the stable connection between the butyl rubber stopper 15 and the pressing cap 2. At the same time, the limiting blocks 151 play a limiting role, which is beneficial to restricting the position of the pressing cap 2 so that the connecting plate 22 can pass through the through groove 110.
[0030] In this embodiment, two positioning blocks 10 are fixed at both the upper and lower ends of the inner wall of the tube body 1. Two positioning grooves 150 are provided on the outer wall of the butyl rubber stopper 15, and the positioning grooves 150 are inserted and matched with the positioning blocks 10. The setting of the positioning grooves 150 and the positioning blocks 10 provides positioning and fixing for the butyl rubber stopper 15, ensures its accurate position in the tube body 1, and thus is beneficial to the stable installation of the pressing cap 2.
[0031] In this embodiment, an adjusting head 14 is coaxially key-connected to the end of the threaded rod 13, and a plurality of anti-slip grooves are provided on the outer wall of the adjusting head 14. This design increases the friction between the adjusting head 14 and the user's hand, making it more stable and easier to operate when rotating the adjusting head 14.
[0032] In this embodiment, the size of the groove 111 is adapted to the size of the slider 12, and the overall shape of the slider 12 is arc-shaped. This design ensures the smooth sliding of the slider 12 within the groove 111, reducing friction and wear, and the arc-shaped design facilitates the better cooperation between the latch 120 on the slider 12 and the card slot 220.
[0033] In this embodiment, the compression cap 2 and the connecting plate 22 are of an integrally formed structure, and both the compression cap 2 and the connecting plate 22 are made of plastic materials. The integrally formed structure enhances the overall strength of the part, and the choice of plastic materials makes the entire structure lightweight and has a certain corrosion resistance, improving the service life of the compression cap 2 and the connecting plate 22.
[0034] It should be added that the fixing base 11 in this embodiment is tightly adhered to the outer wall of the pipe body 1. This tightly adhered manner has the advantages of firm and tight connection between the fixing base 11 and the pipe body 1, ensuring the connection stability between the fixing base 11 and the pipe body 1.
[0035] During specific use, the user first puts the compression cap 2 on the outside of the butyl rubber stopper 15 and inserts the limit groove 21 into alignment with the limit block 151. At the same time, the user passes the connecting plate 22 through the through groove 110, and the compression cap 2 is put on the outside of the butyl rubber stopper 15. Repeat the above steps and put another compression cap 2 on the outside of the butyl rubber stopper 15 on the other side. Subsequently, the user rotates the adjusting head 14, and the adjusting head 14 drives the threaded rod 13 to rotate. As the threaded rod 13 rotates, the slider 12 moves along the inner cavity of the groove 111, and the slider 12 simultaneously drives the latch 120 to move. When the latch 120 snaps into the card slot 220, the connecting plate 22 is fixed within the fixing base 11. At this time, the compression caps 2 on both sides are fixed, and the butyl rubber stopper 15 is stably fixed to both ends of the pipe body 1.
