Description

Technical Field

[0001] This invention relates to the field of medical blood anticoagulation technology, specifically to a medical blood transfusion anticoagulation device for hematological diseases. Background Technology

[0002] In the clinical treatment of hematological diseases, blood transfusion is one of the key means to save patients' lives, especially for patients with severe anemia, coagulation disorders, and other hematological diseases. Timely and safe blood transfusion is directly related to the treatment effect and the patient's life safety. Because hematological disease patients have abnormal blood components (such as thrombocytopenia and clotting factor deficiency), and because blood is prone to coagulation reactions triggered by temperature changes and slowed flow rates after leaving the body during transfusion, if blood coagulates before transfusion, it will not only lead to blockage of the transfusion line and affect transfusion efficiency, but may also cause serious complications such as thrombosis and organ embolism, threatening the patient's life. Therefore, it is essential to thoroughly mix blood with anticoagulant drugs before transfusion to inhibit the activation of clotting factors and prevent blood coagulation. This is an indispensable and crucial step in the transfusion treatment of hematological diseases.

[0003] Currently, the most common methods for mixing blood and anticoagulants in clinical practice are manual shaking. Manual shaking relies on medical staff manually agitating the blood bag, a cumbersome and labor-intensive process. Especially in mass transfusions or emergency resuscitation scenarios, it's difficult to guarantee the timeliness and consistency of mixing. Furthermore, the force, frequency, and direction of manual shaking are random, easily leading to insufficient mixing and uneven drug distribution, resulting in localized blood clotting risks and failing to meet the stringent anticoagulant requirements of hematological patients. In addition, some existing mechanical mixing devices use a single reciprocating oscillation mode, propelling blood flow within the blood bag through a unidirectional force. However, mixing blood and anticoagulants requires multi-directional shearing and agitation. In a single-motion mode, dead zones easily form within the blood bag, making it difficult for the drug to penetrate all areas of the blood, resulting in low mixing efficiency and unstable anticoagulant effects. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a medical blood transfusion anticoagulation device, which solves the problems of low mixing efficiency and unstable anticoagulation effect caused by the single reciprocating swing mode used in some existing mechanical mixing devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a medical blood transfusion anticoagulation device for hematological diseases, comprising a fixed column, a motor 1 fixedly mounted on the outer wall of the fixed column, a swing ring fixedly connected to the output end of the motor 1, a main frame rotatably connected to the inner ring wall of the swing ring, a motor 2 fixedly mounted on the outer wall of the fixed column away from the motor 1, a transmission mechanism provided at the output end of the motor 2, a sleeve connected to the transmission mechanism, the outer wall of the sleeve rotatably connected to the outer wall of the fixed column, a rotating shaft rotatably connected to the inner wall of the sleeve, one end of the rotating shaft rotatably connected to the outer wall of the fixed column, the other end of the rotating shaft fixedly connected to the outer wall of the swing ring, a bevel gear 1 fixedly connected to the outer wall of the sleeve, a bevel gear 2 meshing with the tooth end of the bevel gear 1, and the bevel gear 2 fixedly connected to the outer wall of the main frame.

[0006] Preferably, the transmission mechanism includes a first spur gear and a second spur gear. The first spur gear is fixedly connected to the output end of the second motor, and the tooth end of the first spur gear meshes with the tooth end of the second spur gear. The second spur gear is fixedly connected to the outer wall of the sleeve.

[0007] Preferably, a limiting block is fixedly connected to the outer wall of the main frame, and the outer wall of the limiting block is embedded inside the swing ring and rotatably connected to the swing ring.

[0008] Preferably, an insulation board is fixedly connected to the outer wall and lower surface of the fixed column, a handrail is fixedly connected to the outer wall of the insulation board, and casters are fixedly connected to the lower surface of the insulation board.

[0009] Preferably, a slide rail is fixedly connected to the outer wall of the main frame, a slider is slidably connected inside the slide rail, and a pressing mechanism is fixedly connected to the upper surface of the slider.

[0010] Preferably, the extrusion mechanism includes a fixed rod, the lower surface of which is fixedly connected to the upper surface of the slider, an extrusion rod is fixedly connected to the outer wall of the fixed rod, and an extrusion ball is fixedly connected to the outer wall of the extrusion rod.

[0011] Preferably, a sliding column is fixedly connected to the lower surface of the main frame, a sliding ring is slidably connected to the outer wall of the sliding column, one end of a connecting rod is rotatably connected to the outer wall of the sliding ring, and the other end of the connecting rod is rotatably connected to the lower surface of the slider.

[0012] Preferably, the lower surface of the slip ring is bolted with multiple sets of counterweight rings, the counterweight rings are bolted together, and the upper surface of the slip ring is fixedly connected with a tension spring, the top end of the tension spring being fixedly connected to the lower surface of the main frame.

[0013] Preferably, the inner wall of the main frame is fitted with a sliding plate, the outer wall of the sliding plate can rotate and slide on the inner wall of the main frame, the lower surface of the sliding plate is fixedly connected with a spring, the bottom end of the spring is fixedly connected with a ball, and the bottom surface of the ball can fit against the inner bottom wall of the main frame.

[0014] Preferably, a limiting protrusion is fixedly connected to the inner bottom wall of the main frame. The limiting protrusion is circumferentially arranged, and the upper surface of the limiting protrusion can fit against the bottom surface of the sphere.

[0015] This invention provides a medical transfusion anticoagulation device for hematological diseases. It has the following beneficial effects: 1. This invention uses a motor to drive the swing ring to swing back and forth, and a motor to drive the sleeve to rotate through a transmission mechanism. The main frame rotates while swinging, and the main frame rotates by means of bevel gear transmission, thus forming a multi-dimensional composite motion. This motion can apply a multi-directional and multi-angle mixing force to the blood bag, which can efficiently and evenly promote the mixing of blood and anticoagulant drugs and perform physical anticoagulation, effectively preventing blood coagulation before transfusion.

[0016] 2. The device of the present invention is equipped with multiple sets of sliding rails and sliders and matching extrusion mechanisms along the circumference of the main frame. The extrusion ball is made of medical-grade silicone material, which can simultaneously fit the blood bag from multiple directions. The opening and closing movement of the extrusion mechanism can achieve stable fixation of the blood bag, and at the same time, the extrusion action helps to promote blood mixing, prevents the blood bag from shifting in the compound movement, and further improves the mixing uniformity.

[0017] 3. The slip ring of this invention, through the cooperation of the counterweight ring and the tension spring, utilizes the centrifugal force generated by the shaking of the equipment to automatically achieve the sliding block closing and squeezing, and automatically resets and opens after the centrifugal force disappears, without the need for manual adjustment; at the same time, the counterweight ring adopts a detachable bolt connection design, and the counterweight weight can be adjusted by increasing or decreasing the number, thereby adjusting the squeezing and clamping force, adapting to blood bags of different capacities and specifications, and improving the versatility of the equipment.

[0018] 4. This invention can also utilize the sliding engagement between the slide plate and the inner wall of the main frame, combined with the elastic support structure of the spring and the ball, to allow the slide plate to slide back and forth under the force of the swaying motion and the elasticity of the spring during operation. This causes the blood bag to move synchronously, effectively preventing blood from settling at the bottom of the blood bag and allowing the blood inside the blood bag to flow fully. This further improves the uniformity of mixing the blood with the anticoagulant medication and enhances the anticoagulant effect. Furthermore, through the collision engagement between the circumferential limiting protrusion on the bottom wall of the main frame and the ball, and by utilizing the rotational connection between the slide plate and the main frame, the ball and the limiting protrusion collide during relative rotation, generating vibrations that are transmitted to the blood bag. This causes violent disturbance in the blood, breaking the tendency for blood to settle. Compared to simple sliding mixing, this significantly improves the mixing efficiency and anticoagulant effect.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 - Appendix Figure 7 This invention provides a medical blood transfusion anticoagulation device for hematological diseases, including a fixed column 1. A motor 2 is fixedly installed on the outer wall of the fixed column 1. A swing ring 3 is fixedly connected to the output end of the motor 2. A main frame 4 is rotatably connected to the inner ring wall of the swing ring 3. A motor 6 is fixedly installed on the outer wall of the fixed column 1 on the side away from the motor 2. A transmission mechanism 7 is provided at the output end of the motor 6. A sleeve 8 is rotatably connected to the transmission mechanism 7. The outer wall of the sleeve 8 is rotatably connected to the outer wall of the fixed column 1. A rotating shaft 26 is rotatably connected to the inner wall of the sleeve 8. One end of the rotating shaft 26 is rotatably connected to the outer wall of the fixed column 1. The other end of the rotating shaft 26 is fixedly connected to the outer wall of the swing ring 3. A bevel gear 9 is fixedly connected to the outer wall of the sleeve 8. A bevel gear 10 is meshed with the tooth end of the bevel gear 9. The bevel gear 10 is fixedly connected to the outer wall of the main frame 4.

[0023] Specifically, the medical hematology transfusion anticoagulation device disclosed in this invention is primarily designed to solve the technical problem of blood coagulation during transfusion in hematology patients. It achieves efficient mixing of blood and anticoagulant drugs through compound motion. The device includes a fixed column 1, with two sets of fixed columns located on either side of the main frame 4. A motor 2 is mounted on the outer wall of the fixed column 1, secured with bolts to ensure no displacement or vibration during operation. The output end of the motor 2 is fixedly connected to a swing ring 3, driving the swing ring 3 to reciprocate. A support is fixedly mounted on the fixed column 1, rotatably connected to the swing ring 3 to support its rotation. The swinging motion creates an initial shaking force on the blood bag placed inside. The inner ring wall of the swing ring 3 is rotatably connected to the main frame 4. On the side away from the motor 2, a second motor 6 is also fixedly mounted on the outer wall of the fixed column 1. The output end of the second motor 6 is equipped with a transmission mechanism 7, which transmits the power of the second motor 6 to the sleeve 8. The outer wall of sleeve 8 is rotatably connected to the outer wall of fixed column 1, and the inner wall of sleeve 8 is rotatably connected to rotating shaft 26. One end of rotating shaft 26 is rotatably connected to the outer wall of fixed column 1, and the other end is fixedly connected to the outer wall of swing ring 3. Rotating shaft 26 provides auxiliary support for swing ring 3, further improving the structural stability of swing ring 3 during swing. A bevel gear 9 is fixedly connected to the outer wall of sleeve 8. Bevel gear 9 meshes with bevel gear 10 fixedly connected to the outer wall of main frame 4, forming a bevel gear transmission mechanism. When the equipment is started, the fixed column 1 provides stable support. The motor controller controls the forward and reverse rotation, start and stop, and speed of motor 2 to achieve reciprocating oscillation. After motor 2 starts, it drives the swing ring 3 to oscillate back and forth, achieving the initial shaking of the blood bag. At the same time, motor 6 on the other side starts, and the power is transmitted to the sleeve 8 through the transmission mechanism 7, driving the sleeve 8 to rotate. During the rotation of the sleeve 8, the bevel gear 9 rotates synchronously. The central axis of bevel gear 9 and the output end of motor 2 coincide. Bevel gear 9 drives bevel gear 10 to rotate through meshing transmission, thereby driving the main frame 4 to rotate while swinging with the swing ring 3. Through the combined oscillation and rotation of the main frame 4, the blood bag inside can be subjected to forces from multiple directions and angles, thereby achieving full and uniform mixing of blood and anticoagulant drugs, effectively preventing blood coagulation before transfusion.

[0024] The transmission mechanism 7 includes a first spur gear 701 and a second spur gear 702. The first spur gear 701 is fixedly connected to the output end of the second motor 6. The tooth end of the first spur gear 701 meshes with the tooth end of the second spur gear 702. The second spur gear 702 is fixedly connected to the outer wall of the sleeve 8.

[0025] Specifically, in the transmission mechanism 7 used in this equipment, a first spur gear 701 is fixedly connected to the output end of a second motor 6. The connection method adopts a keyed connection with end face pressing structure, which ensures stable power transmission between the first spur gear 701 and the output shaft of the second motor 6. The tooth ends of the first spur gear 701 and the tooth ends of the second spur gear 702 form a meshing connection. The second spur gear 702 is fixedly connected to the outer wall of the sleeve 8, and its connection method also adopts a keyed connection with a locking nut for reinforcement, ensuring that the second spur gear 702 and the sleeve 8 can rotate synchronously, and completely transmitting the power received by the second spur gear 702 to the sleeve 8. When motor 26 starts, the output shaft of motor 26 drives spur gear 1 701 to rotate around its own axis. spur gear 1 701 drives spur gear 2 702 to rotate synchronously through the meshing action of the tooth ends. Since spur gear 2 702 is fixedly connected to sleeve 8, when spur gear 2 702 rotates, it will drive sleeve 8 to rotate around the axis of fixed column 1, thereby completing the process of power transmission from motor 26 to sleeve 8.

[0026] The outer wall of the main frame 4 is fixedly connected to a limiting block 5, and the outer wall of the limiting block 5 is embedded in the interior of the swing ring 3 and rotates and connects with the swing ring 3.

[0027] Specifically, the main frame 4 consists of multiple annular frames and vertical rods. Limiting blocks 5 are fixedly connected to the outer wall of the main frame 4. A limiting groove is provided inside the swing ring 3, supporting the rotation of the limiting blocks 5. The limiting blocks 5 are embedded in the limiting groove of the swing ring 3 and form a rotational connection with the swing ring 3. The limiting blocks 5 not only provide radial support to the main frame 4 but also ensure the coaxiality of the main frame 4 during rotation, preventing the main frame 4 from shifting or tilting, and ensuring the stability of the rotational motion. The limiting blocks 5 continuously provide support and guidance during the rotation of the main frame 4, ensuring the stable and reliable rotational motion of the main frame 4.

[0028] An insulation board 19 is fixedly connected to the outer wall and lower surface of the fixed column 1. A handrail 21 is fixedly connected to the outer wall of the insulation board 19, and a caster wheel 20 is fixedly connected to the lower surface of the insulation board 19.

[0029] Specifically, to ensure the temperature stability of blood during transfusion and prevent temperature changes from affecting its activity and anticoagulant effect, an insulation plate 19 is fixedly connected to the outer wall and lower surface of the fixed column 1. The insulation plate 19 effectively reduces heat exchange between the inside of the equipment and the external environment, maintaining a stable temperature for the blood bags inside the equipment. The insulation plate 19 is connected to the fixed column 1 by a combination of adhesive bonding and bolt fastening, ensuring a firm and reliable connection and forming an effective insulation space. A handle 21 is fixedly connected to the outer wall of the insulation plate 19 for easy gripping and pushing of the equipment by the operator. Casters 20 are fixedly connected to the lower surface of the insulation plate 19, each equipped with a braking device. When the equipment moves to the designated position, the casters 20 can be locked by the braking device to prevent accidental slippage. Through the coordinated arrangement of the insulation plate 19, handle 21, and casters 20, convenient movement and stable parking of the equipment are achieved, improving its practicality and ease of operation.

[0030] The outer wall of the main frame 4 is fixedly connected to a slide rail 11, the slide rail 11 is slidably connected to a slider 12, and the upper surface of the slider 12 is fixedly connected to a pressing mechanism 13.

[0031] Specifically, multiple sets of slide rails 11 are evenly arranged circumferentially along the outer wall of the main frame 4. The specific number can be adjusted according to the size of the main frame 4 and the specifications of the blood bag, usually 3-4 sets are set to ensure that a uniform force can be applied to the blood bag from multiple directions. The slide rails 11 are provided with grooves to provide precise guidance for the sliding of the slider 12. The slider 12 is slidably connected inside the slide rails 11, and the structure of the slider 12 is adapted to the grooves of the slide rails 11. A compression mechanism 13 is fixedly connected to the upper surface of the slider 12, and the two are connected by bolts to ensure that the compression mechanism 13 can slide synchronously with the slider 12. The slide rails 11 provide stable support and guidance for the sliding of the slider 12. Through the cooperative arrangement of multiple sets of slide rails 11 and sliders 12, multiple compression mechanisms 13 can open and close synchronously, providing a structural basis for subsequent multi-directional compression and fixation of the blood bag and auxiliary mixing.

[0032] The extrusion mechanism 13 includes a fixed rod 1301, the lower surface of which is fixedly connected to the upper surface of the slider 12, an extrusion rod 1302 is fixedly connected to the outer wall of the fixed rod 1301, and an extrusion ball 1303 is fixedly connected to the outer wall of the extrusion rod 1302.

[0033] Specifically, the lower surface of the fixing rod 1301 is fixedly connected to the upper surface of the slider 12 by bolts. A squeezing rod 1302 is fixedly connected to the outer wall of the fixing rod 1301. Multiple squeezing rods 1302 are evenly distributed vertically along the fixing rod 1301; the specific number can be adjusted according to the size of the blood bag. The squeezing rods 1302 and the fixing rod 1301 are connected by welding or integral molding to ensure a firm and reliable connection, stably transmitting the movement of the fixing rod 1301 to the squeezing ball 1303. A squeezing ball 1303, made of medical-grade silicone, is fixedly connected to the outer wall of the squeezing rod 1302. The squeezing ball 1303 can pass through the main frame 4, extending into the interior of the main frame 4 and directly contacting the blood bag. When the slider 12 slides along the slide rail 11, it drives the fixing rod 1301 to slide synchronously, and the fixing rod 1301 then drives the squeezing rods 1302 and the squeezing ball 1303 to move together. When the squeeze ball 1303 slides towards the center of the main frame 4, it can compress the blood bag placed inside the main frame 4, thus fixing the blood bag. This is used in hematology departments, ICUs, operating rooms, and other places to process special blood products that are extremely sensitive to mixing uniformity and anticoagulation effects, such as platelets, frozen plasma, and stem cell preparations. Insufficient mixing of these blood products can easily lead to coagulation or cell damage, and manual shaking cannot guarantee consistent quality. Simultaneously, the squeeze balls 1303 of multiple compression mechanisms 13 compress the blood bag from different directions, which can help promote the mixing of blood and anticoagulant drugs inside the blood bag, further improving the mixing effect.

[0034] A sliding column 14 is fixedly connected to the lower surface of the main frame 4. A sliding ring 15 is slidably connected to the outer wall of the sliding column 14. One end of a connecting rod 16 is rotatably connected to the outer wall of the sliding ring 15. The other end of the connecting rod 16 is rotatably connected to the lower surface of the slider 12.

[0035] Specifically, the slide post 14 is vertically positioned to provide smooth guidance for the sliding ring 15. The slide ring 15 is slidably connected to the outer wall of the slide post 14, and the inner diameter of the slide ring 15 is matched with the outer diameter of the slide post 14. A clearance fit is used between the two to ensure that the slide ring 15 can slide smoothly along the axial direction of the slide post 14. The outer wall of the slide ring 15 is rotatably connected to one end of the connecting rod 16 via a pin. The other end of the connecting rod 16 is also rotatably connected to the lower surface of the slider 12 via a pin. This structure drives the rotation of the connecting rod 16 through the sliding of the slide ring 15, thereby enabling the slider 12 to slide along the slide rail 11. When the slip ring 15 slides downward along the slide post 14, it generates a centripetal pulling force on the slider 12 through the connecting rod 16, causing multiple sliders 12 to converge synchronously towards the center of the main frame 4, thereby driving the compression mechanism 13 to compress and fix the blood bag; when the slip ring 15 slides upward along the slide post 14, the pulling force of the connecting rod 16 on the slider 12 disappears, and the slider 12 moves away from the center of the main frame 4 under the action of the subsequent reset mechanism, thereby opening the compression mechanism 13.

[0036] The lower surface of the slip ring 15 is bolted with multiple sets of counterweight rings 17, which are bolted together. The upper surface of the slip ring 15 is fixedly connected with a tension spring 18, and the top of the tension spring 18 is fixedly connected to the lower surface of the main frame 4.

[0037] Specifically, to achieve adaptive opening and closing of the compression mechanism 13, multiple sets of counterweight rings 17 are bolted to the lower surface of the slip ring 15. The counterweight rings 17 are also fixed together using bolts. This detachable connection method allows for adjustment of the number of counterweight rings 17 according to actual usage requirements. The counterweight rings 17 are fitted onto the outer wall of the sliding column 14 and can slide along the axis of the sliding column 14 together with the slip ring 15. A tension spring 18 is fixedly connected to the upper surface of the slip ring 15, and the top of the tension spring 18 is fixedly connected to the lower surface of the main frame 4. The main frame 4 can initially limit the placement of the blood bag. When the equipment starts to shake, centrifugal force is generated. Under the action of centrifugal force, the counterweight rings 17 generate a downward pulling force, pulling the slip ring 15 downward along the sliding column 14. Through the connecting rod 16, the slider 12 is driven to converge towards the center of the main frame 4, causing the compression mechanism 13 to compress and fix the blood bag. When the main frame 4 returns to an upright position, the centrifugal force generated by the shaking of the equipment disappears. At this time, the elastic tension of the tension spring 18 will drive the slip ring 15 to slide upward along the sliding column 14, realizing the reset of the slip ring 15. Then, through the connecting rod 16, the slider 12 will move away from the center of the main frame 4, opening the squeezing mechanism 13, making it convenient for operators to handle blood bags. This structure can automatically adjust the clamping force of the squeezing mechanism 13 according to the degree of shaking of the equipment, i.e., the magnitude of the centrifugal force. The more violently the equipment shakes, the greater the centrifugal force, the greater the tension of the counterweight ring 17 on the slip ring 15, and the greater the clamping force of the squeezing mechanism 13, which can effectively prevent the blood bag from shifting during violent shaking. When the equipment stops shaking, the squeezing mechanism 13 automatically opens for easy operation. At the same time, operators can also adjust the counterweight weight by increasing or decreasing the number of counterweight rings 17, thereby adjusting the magnitude of the centrifugal force to meet the fixing requirements of blood bags of different specifications and capacities. The counterweight ring 17 is fitted onto the outer wall of the sliding column 14. The structure is compact and will not affect the movement of other components. The adjustment method is simple and convenient, which further improves the versatility and practicality of the equipment.

[0038] Example 2 The inner wall of the main frame 4 is fitted with a slide plate 22. The outer wall of the slide plate 22 can rotate and slide on the inner wall of the main frame 4. A spring 23 is fixedly connected to the lower surface of the slide plate 22. A ball 24 is fixedly connected to the bottom end of the spring 23. The bottom surface of the ball 24 can fit against the inner bottom wall of the main frame 4.

[0039] Specifically, in this embodiment, the slide plate 22 is fitted against the inner wall of the main frame 4, and the outer wall of the slide plate 22 slides in cooperation with the inner wall of the main frame 4, allowing the slide plate 22 to slide vertically up and down inside the main frame 4. A spring 23 is fixedly connected to the lower surface of the slide plate 22. The spring 23 is made of high-strength spring steel and has good elasticity. A ball 24 is fixedly connected to the bottom end of the spring 23. The slide plate 22 is used to place blood bags, which are placed on the upper surface of the slide plate 22. The up and down sliding of the slide plate 22 drives the blood bags to move up and down synchronously. In hematology departments, ICUs, operating rooms, and other places, this is used to process special blood products such as platelets, frozen plasma, and stem cell preparations that are extremely sensitive to the uniformity of mixing and anticoagulation effects. If these blood products are not mixed sufficiently, they are prone to coagulation or cell damage, and manual shaking cannot guarantee consistent quality. When the equipment is working, the swinging and rotating motion of the main frame 4 will drive the slide plate 22 to move together. At the same time, under the force generated by the shaking of the equipment and the elasticity of the spring 23, the slide plate 22 can slide up and down reciprocally inside the main frame 4. This up-and-down sliding motion further prevents blood from settling at the bottom of the blood bag, allowing the blood inside the bag to flow fully and mix more evenly with the anticoagulant medication, effectively improving the anticoagulant effect.

[0040] Example 3 The inner bottom wall of the main frame 4 is fixedly connected to a limiting protrusion 25, which is circumferentially arranged, and the upper surface of the limiting protrusion 25 can fit against the bottom surface of the sphere 24.

[0041] Specifically, Embodiment 3 further optimizes Embodiment 2. In this embodiment, the outer wall of the slide plate 22 can not only slide on the inner wall of the main frame 4, but also rotate freely on the inner wall of the main frame 4, ensuring that the rotation and sliding of the slide plate 22 can proceed smoothly, while ensuring the stability of the connection. A limiting protrusion 25 is fixedly connected to the inner bottom wall of the main frame 4. Multiple sets of limiting protrusions 25 are evenly arranged along the circumference of the inner bottom wall of the main frame 4. The upper surface of the limiting protrusion 25 can contact the bottom surface of the ball 24, providing support and limiting for the ball 24. When the main frame 4 swings and rotates under the drive of the motor, relative rotation can occur between the slide plate 22 and the main frame 4 due to the rotatable connection between them. During this relative rotation, the bottom surface of the ball 24 will continuously collide with the circumferentially arranged limiting protrusions 25, and the force generated by the collision will cause the slide plate 22 to vibrate. This vibration can be transmitted to the blood bag placed on the slide plate 22, causing violent disturbance to the blood inside the blood bag, further breaking the tendency of blood to settle, promoting thorough mixing of blood and anticoagulant drugs, and significantly improving the anticoagulant effect and mixing efficiency.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
