Description

Technical Field

[0001] This utility model relates to the field of platelet-rich plasma preparation technology, and in particular to an apparatus for preparing allogeneic platelet-rich plasma. Background Technology

[0002] Platelet-rich plasma (PRP), as a bioactive preparation, has broad application prospects in regenerative medicine, tissue repair, and wound healing. Allogeneic PRP, a platelet concentrate obtained from healthy donors, can overcome the limitations of autologous PRP in emergency situations and specific patient groups. With the deepening development of precision medicine, the demand for high-quality allogeneic PRP is increasing. Particularly in geriatric medicine, severe trauma, and the treatment of chronic, difficult-to-heal wounds, higher requirements are being placed on preparation devices.

[0003] A search of Chinese Patent Publication No. CN217221033U reveals a device comprising a housing with an internal centrifuge chamber. A rotating shaft is movably mounted within the centrifuge chamber, and a cross-shaped movable platform is movably mounted at the top of the rotating shaft. Semi-circular fixing plates are fixedly mounted at each of the four corners of the cross-shaped movable platform. A movable frustum is movably mounted inside each of the semi-circular fixing plates. Two spring grooves are provided on the outer surface of each semi-circular fixing plate, and compression springs are movably mounted inside each of these spring grooves. This invention, through the cooperation of the fixed arc plate and the outer groove of the frustum, allows the device to be laterally engaged with the movable frustum in the semi-circular fixing plate during use, thus locking the fixed arc plate into the outer groove of the frustum. This secures the movable frustum on the outer surface of the semi-circular fixing plate, facilitating the assembly and disassembly of the movable frustum and the storage and retrieval of blood samples from the sample placement slot on the surface of the movable frustum.

[0004] While the aforementioned technology facilitates the storage and retrieval of blood samples through the disassembly and assembly of the movable stage, during the storage and retrieval process, the blood samples may be spilled and scattered in the centrifuge chamber due to collisions. The movable stage fixed on the drive mechanism affects the cleaning efficiency of the centrifuge chamber, thereby affecting the preparation efficiency of platelet-rich plasma. Therefore, a device for preparing allogeneic platelet-rich plasma is proposed to solve the above problems. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-3 An embodiment of this utility model provides a device for preparing allogeneic platelet-rich plasma, comprising a housing 1, a top cover 2 rotatably connected to the top of the housing 1, a centrifuge tank 3 fixedly connected to the middle of the housing 1, a drive assembly installed inside the housing 1, an insert block 19 fixedly connected to the top of the drive assembly, the drive assembly including a servo motor 15, the servo motor 15 fixedly connected inside the housing 1, a rotating rod 22 fixedly connected to the output end of the servo motor 15, the insert block 19 fixedly connected to the other end of the rotating rod 22, a locking block 14 slidably connected to the outer periphery of the insert block 19, a tray 16 fixedly connected to the outer periphery of the locking block 14, a locking plate 4 fixedly connected to the top of the tray 16, a sample 5 inserted into the middle of the locking plate 4, and a sealing ring 10 fixedly connected to the top of the housing 1. First, insert sample 5 into card plate 4 and merge top cover 2 with box body 1. At the same time, the sealing performance between box body 1 and top cover 2 is improved by sealing ring 10, so that servo motor 15 can drive rotating rod 22, so that rotating rod 22 drives tray 16 through insert block 19, thereby allowing sample 5 to be prepared under the centrifugal action of rotation.

[0036] Reference Figures 1-3A slider 25 is slidably connected to the middle of the locking block 14. A round rod 24 is fixedly connected to the bottom of the slider 25. An elastic component is installed on the outer periphery of the round rod 24. Insert rods 20 are fixedly connected to the left and right sides of the bottom of the slider 25. The insert rods 20 pass through the locking block 14 and are slidably connected to the middle of the insert block 19. A pull rod 6 is fixedly connected to the top of the slider 25. The elastic component includes a stop block 21, which is fixedly connected to the bottom end of the round rod 24. A compression spring 23 is sleeved on the outer periphery of the round rod 24. A groove 18 is opened in the middle of the locking block 14. The slider 25 is slidably connected to the middle of the groove 18. A through groove 7 is opened in the middle of the locking block 14. The groove 18 and the through groove 7 are connected. When the blood sample is spilled after prolonged use, pulling the lever 6 will drive the slider 25, causing the slider 25 to slide the insertion rod 20 out from the middle of the insertion block 19. After the insertion rod 20 slides out from the middle of the groove 18, rotating the lever 6 will drive the insertion rod 20 to rotate into the through groove 7, so that the insertion rod 20 contacts the top of the insertion block 19. This will allow the locking block 14 to slide out from the outer periphery of the insertion block 19, and then the tray 16 and the locking plate 4 can be removed, so as to reduce the obstruction to the cleaning of the centrifuge tank 3 and allow the equipment to quickly enter the working state.

[0037] Reference Figures 4-6 An airflow slot 17 is provided in the middle of the housing 1. A second fan 27 is fixedly connected to the middle of the housing 1. A semiconductor cooling chip 26 is fixedly connected to the middle of the housing 1. An air outlet 8 is provided on the right side of the housing 1. A heat dissipation assembly is installed in the middle of the housing 1. The heat dissipation assembly includes a first fan 12, which is fixedly connected to the middle of the housing 1. A heat dissipation vent 9 is provided in the middle of the housing 1. The first fan 12 is located in the middle of the heat dissipation vent 9. A flow guide ring 13 is fixedly connected between the housing 1 and the centrifuge tank 3. A filter screen 11 is fixedly connected to the left side of the housing 1. During the preparation process, the thermoelectric cooler 26 is first energized to cool one side of the thermoelectric cooler 26. At the same time, the low-temperature air is sent into the airflow channel 17 by the second fan 27. The flow time of the low-temperature air in the airflow channel 17 is increased by the flow ring 13, so that the centrifuge tank 3 and the sample 5 can always be kept at a low temperature, thereby avoiding premature activation of platelets and preserving therapeutic potential. At the same time, the filter screen 11 can prevent dust from adhering to the centrifuge tank 3 with the airflow. While driving the second fan 27, the first fan 12 is also driven so that the heat generated by the thermoelectric cooler 26 can be quickly discharged through the heat dissipation port 9, thereby preventing heat from accumulating in the chamber 1.

[0038] Working principle: When centrifuge tank 3 needs to be cleaned, the slider 25 is pulled by the lever 6, so that the slider 25 drives the insertion rod 20 to slide out from the middle of the insertion block 19. The slider 25 is rotated to align the insertion rod 20 with the through groove 7, so that the slider 25 and the insertion rod 20 can slide out from the middle of the locking block 14, so that the locking block 14 can be removed from the middle of the insertion block 19, thereby reducing obstruction and improving cleaning convenience.

[0039] During the preparation of platelet-rich plasma, the driving semiconductor cooling chip 26 generates cold air, and the low-temperature air is sent into the airflow channel 17 by the fan 27. At the same time, the flow time of the cold air in the airflow channel 17 is increased under the action of the drainage ring 13, so that the centrifuge tank 3 and the sample 5 in the centrifuge tank 3 are kept at a low temperature, thereby inhibiting premature activation of the sample 5.
