Description

Technical Field

[0001] This utility model relates to the field of blood inhibitory factor extraction technology, and in particular to a human blood inhibitory factor extraction device. Background Technology

[0002] Blood circulating in the blood vessels of the human or animal body performs multiple functions, including: transporting oxygen inhaled from the lungs to tissue cells; transporting carbon dioxide from tissues to the lungs and releasing it to the outside; transporting nutrients absorbed from the digestive tract to organs or tissue cells as tissue breakdown products; transporting excess substances to the kidneys for excretion; transporting hormones secreted by endocrine glands to target organs and tissues; evenly distributing body heat to maintain body temperature; and destroying and detoxifying bacteria and foreign substances that invade the body. While blood is used as a key indicator for assessing various diseases or health conditions, platelets and white blood cells rich in growth factors are used for therapeutic purposes. Blood contains red blood cells, white blood cells, and platelets, with platelets primarily found in plasma. Plasma is divided into platelet-rich plasma and platelet-poor plasma layers. Platelet-rich plasma, located relatively low in the plasma, contains growth factors such as cytokines, platelet-derived growth factor, transforming growth factor-β1, and vascular endothelial growth factor. If red blood cells enter the human body, they can cause great pain and inflammation. Therefore, the focus is on the technology of collecting platelet-concentrated blood (PRP) after removing red blood cells.

[0003] Publication (Announcement) No.: CN106176214B A blood separation and extraction apparatus for extracting platelet-rich growth factors is described. The apparatus performs centrifugation while blood is contained in a receiving space formed at the lower part of the main tube. White blood cells, which are the separation layer of the centrifuged blood, are injected into the separation space of the main tube. Then, an upper cover is attached in a manner connected to the passage of the main tube so that only concentrated platelets can be collected and extracted. Thus, blood separation and concentrated platelet extraction can be performed simultaneously through a single centrifugation and in a single container.

[0004] The existing main tube makes it inconvenient to export the separated blood components during centrifugation. The main tube needs to be removed to export the separated liquid before a second separation operation is performed, which reduces work efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing main tubes are inconvenient to export the separated blood components during centrifugation, requiring the main tube to be removed and the separated liquid exported before a second separation operation, which reduces work efficiency. The proposed invention is a human blood inhibitory factor extraction device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A human blood inhibitory factor extraction device includes:

[0008] The base has two straight plates fixedly installed on its top, and each of the two straight plates is provided with a synchronous rotation mechanism;

[0009] A circular ring is installed between two synchronously rotating mechanisms. A support cylinder is rotatably installed inside the circular ring, and a main tube is installed inside the support cylinder.

[0010] A centrifugal rotation mechanism is installed on the top of the base, and a driven gear is fixedly installed at the bottom of the support cylinder. The driven gear is adapted to the centrifugal rotation mechanism.

[0011] Preferably, the base has a built-in power supply and control chip, and a control switch and indicator light are provided on the outside of the base.

[0012] Preferably, the two synchronous rotation mechanisms include two synchronous motors, which are mounted on the outer sides of two straight plates. Two rotating rods are mounted on the output shafts of the two synchronous motors, and the inner ends of the two rotating rods are fixedly mounted to a ring. The two synchronous motors drive the two rotating rods to rotate 90-120 degrees. The two rotating rods drive the main tube to flip through the ring and support cylinder, which can export the centrifugally separated liquid.

[0013] Preferably, a rotating ring is fixedly installed on the outer side of the support cylinder, and a limiting groove is formed on the inner wall of the ring. The rotating ring is slidably connected to the inner wall of the limiting groove to ensure that the support cylinder rotates stably within the ring.

[0014] Preferably, the outer side of the support cylinder is symmetrically threaded with two screws, each screw has a handle fixedly installed at its outer end, and each screw has a rubber sheet at its inner end, both rubber sheets being in contact with the main tube; by rotating the two handles in sequence, the two handles drive the two screws to rotate, and the two screws press and fix the main tube through the two rubber pads.

[0015] Preferably, the centrifugal rotation mechanism includes a servo motor, and a drive gear is mounted on the output shaft of the servo motor. The driven gear cooperates with the drive gear. The servo motor drives the drive gear to rotate, and the drive gear drives the support cylinder to rotate through the driven gear. The support cylinder drives the main tube to rotate centrifugally.

[0016] Preferably, a rubber pad is installed on the bottom inner wall of the support cylinder, and the top of the rubber pad is arc-shaped to support the main tube.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] This method involves placing the main tube inside the support cylinder, rotating two handles in sequence, which in turn rotate two screws. The two screws then press and fix the main tube through two rubber pads. Blood is then added into the main tube. The servo motor drives the drive gear to rotate, which in turn drives the support cylinder to rotate through the passive gear. The support cylinder then drives the main tube to rotate, causing the main tube to perform centrifugal operation.

[0019] In this design, two synchronous motors drive two rotating rods to rotate 90-120 degrees. The two rotating rods, through a ring and a support cylinder, cause the main tube to flip, which can export the centrifugally separated liquid. Then, the two synchronous motors control the main tube to reset.

[0020] This invention has a simple structure and can export the separated blood components without frequently unfastening the main tube, thus improving work efficiency. Attached Figure Description

The two synchronous motors 19 drive the two rotating rods 18 to rotate 90-120 degrees. The two rotating rods 18 drive the main tube 8 to flip through the ring 14 and the support cylinder 9, which can export the centrifugally separated liquid.

[0033] Reference Figure 2 , Figure 3 , Figure 4 In this embodiment, a rotating ring 16 is fixedly installed on the outer side of the support cylinder 9, and a limiting groove 15 is formed on the inner wall of the ring 14. The rotating ring 16 is slidably connected to the inner wall of the limiting groove 15 to ensure that the support cylinder 9 rotates stably within the ring 14.

[0034] Reference Figure 2 In this embodiment, two screws 11 are symmetrically threaded on the outer side of the support cylinder 9. A handle 12 is fixedly installed on the outer end of each screw 11, and a rubber sheet 13 is provided on the inner end of each screw 11. Both rubber sheets 13 are in contact with the main tube 8. When the two handles 12 are rotated in sequence, the two handles 12 drive the two screws 11 to rotate, and the two screws 11 press and fix the main tube 8 through the two rubber pads 10.

[0035] Reference Figure 1 In this embodiment, the centrifugal rotation mechanism includes a servo motor 5, and a drive gear 6 is mounted on the output shaft of the servo motor 5.

The rotating rods 18, through the ring 14 and the support cylinder 9, cause the main tube 8 to flip, allowing the centrifuged liquid to be discharged. The two synchronous motors 19 then control the main tube 8 to reset, and a second centrifugation is performed until the desired inhibitory factor is extracted. Finally, the two screws 11 are rotated in the opposite direction to release the fixation on the main tube 8, allowing it to be removed.
