Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary devices, specifically to a portable blood sample anticoagulation and mixing device. Background Technology

[0002] In medical testing, blood samples need to be thoroughly mixed with anticoagulants promptly after collection to avoid blood clotting affecting the accuracy of test results. Currently, there are two main mixing methods commonly used in clinical practice: one is for medical staff to manually shake the blood collection tubes, and the other is to use a desktop electric mixer.

[0003] However, existing blood sample anticoagulation and mixing devices still have many problems that fail to meet clinical needs, as follows: 1. Existing desktop electric mixers are large and heavy, and rely on mains power, making them unsuitable for use in scenarios such as ambulances and community clinics where there is no fixed power source and frequent movement is required.

[0004] 2. The traditional method of manually shaking blood collection tubes relies on the experience of medical staff to control the force and frequency, which can easily lead to problems such as "insufficient force causing anticoagulant to deposit at the bottom of the tube and uneven mixing" or "excessive force causing blood cells to rupture". 3. Unstable blood collection tube fixation and poor adaptability: The existing devices mostly have a fixed inner diameter design for the placement of blood collection tubes, which can only be used for a single size of blood collection tube. They cannot be used for the 10mL and 15mL blood collection tubes commonly used in clinical practice. Moreover, the placement structure is mostly made of rigid plastic material, which makes the blood collection tubes easy to move up and down or collide with the placement structure during the mixing process, resulting in damage to the blood collection tubes and contamination of the specimen.

[0005] Therefore, those skilled in the art have provided a portable blood sample anticoagulation mixing device to solve the problems mentioned in the background art. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a portable blood sample anticoagulation mixing device. It includes a mixing support base and a detachable sealing protective cover located on the upper end of the mixing support base, wherein a carrying handle is fixedly connected to the upper end of the sealing protective cover. It also includes a mixing mechanism, wherein the mixing support base has a lifting limit groove inside, and the lower end of the mixing mechanism is slidably connected inside the lifting limit groove. The mixing mechanism includes a lifting limit column fixedly connected to the bottom of the lifting limit groove, a lifting connecting drive block slidably sleeved on the outside of the lifting limit column, a lifting connecting drive column fixedly connected to the upper end of the lifting connecting drive block, and a lifting connecting drive disc fixedly connected to the upper end of the lifting connecting drive column. A spring is fixedly connected between the lifting connecting drive block and the bottom of the lifting limit groove, and multiple sets of drive placement mechanisms are connected to the outside of the lifting connecting drive block.

[0007] Preferably, the drive placement mechanism includes a rack fixedly connected to the outside of the lifting drive block, two sets of rotating connecting seats fixedly connected to the upper end of the mixing support base, a rotating shaft rotatably connected between the two sets of rotating connecting seats, a gear fixedly sleeved on the outside of the rotating shaft, and a mounting bracket.

[0008] Preferably, the drive placement mechanism further includes a test tube placement sleeve fixedly connected to the upper end of the mounting frame, and a rubber anti-slip pad fixedly connected to the inner wall of the test tube placement sleeve, wherein multiple sets of rubber protrusions are fixedly connected to the inner wall of the rubber anti-slip pad.

[0009] Preferably, the gear is meshed with the rack.

[0010] Preferably, the spring is sleeved on the outside of the lifting limit post.

[0011] Preferably, the lower end of the lifting connecting drive block is provided with a lifting limit hole, which is slidably sleeved on the outside of the lifting limit column.

[0012] Preferably, the upper end of the mixing support base is provided with a sealing mounting ring groove, the inner wall of the sealing mounting ring groove is provided with an external thread, the inner wall of the lower end of the sealing protective cover is provided with an internal thread, and the lower end of the sealing protective cover is threadedly connected to the inside of the sealing mounting ring groove through the cooperation of the internal and external threads.

[0013] The technical effects and advantages of this utility model are as follows: 1. Significantly improved portability, perfectly adapted to mobile scenarios: The device features a compact design, with a detachable mixing support base and a sealed protective cover. When closed, it is small in size and lightweight. The upper part of the sealed protective cover has a dedicated carrying handle, making it easy for medical staff to hold and carry. It can be manually pressed by staff in conjunction with a spring to reset, requiring no power supply and solving the problems of "poor portability and reliance on mains power" of existing devices.

[0014] 2. The mixing effect is uniform and stable, avoiding damage to the specimen: The device achieves bidirectional oscillation of the blood collection tube by pressing and shaking, which can drive the liquid inside the tube to form deep convection, avoid anticoagulant deposition, and solve the problems of uneven mixing caused by manual shaking and blood cell rupture caused by excessive force in the existing technology.

[0015] 3. The blood collection tubes are securely fixed and highly adaptable. The inner wall of the test tube placement sleeve is equipped with a rubber anti-slip pad and multiple sets of rubber protrusions. The elasticity of the rubber material allows for adaptive adjustment of the inner diameter, solving the problems of fixed inner diameter and poor adaptability of existing devices. The cushioning effect of the rubber material can prevent hard collisions between the blood collection tube and the test tube placement sleeve, reducing the risk of blood collection tube breakage.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose. Example 1

[0018] Please see Figures 1-4This embodiment provides a portable blood sample anticoagulation mixing device, including a mixing support base 1 and a detachably connected sealing protective cover 2 located on the upper end of the mixing support base 1. A carrying handle 3 is fixedly connected to the upper end of the sealing protective cover 2. A sealing mounting ring groove 4 is formed on the upper end of the mixing support base 1. An external thread is formed on the inner wall of the sealing mounting ring groove 4. An internal thread is formed on the inner wall of the lower end of the sealing protective cover 2. The lower end of the sealing protective cover 2 is threadedly connected to the inside of the sealing mounting ring groove 4 through the cooperation of the internal thread and the external thread. A lifting limit groove 5 is formed inside the mixing support base 1. The device also includes a mixing mechanism, the lower end of which is slidably connected to the inside of the lifting limit groove 5.

[0019] Among them, the mixing support base 1 serves as the core load-bearing structure of the device, providing a stable installation foundation for all internal mechanisms such as the mixing mechanism and the drive placement mechanism. Meanwhile, the lifting limit groove 5 and the sealing installation ring groove 4 at the top of the base respectively limit the movement of the mixing mechanism and seal the connection with the sealing protective cover, ensuring the overall structural stability of the device.

[0020] The sealing protective cover 2 is fixed by engaging the internal thread at its lower end with the external thread of the sealing mounting ring groove 4 at the upper end of the mixing support base 1. This allows for a threaded connection, which can completely enclose the internal mixing mechanism, drive placement mechanism, and blood collection tubes, preventing external dust and liquids from entering and affecting the operation of the equipment when it is not in use.

[0021] The carrying handle 3 is fixed to the upper end of the sealed protective cover 2, making it easy for medical staff to hold and carry the device. It is especially suitable for mobile scenarios such as emergency rooms and pre-hospital emergency care, directly improving the portability of the device.

[0022] The external thread on the inner wall of the sealing installation ring groove 4 engages with the internal thread of the sealing protective cover 2 to achieve a detachable and sealed connection between the two, which ensures the sealing performance when the device is closed and facilitates the opening and removal of blood collection tubes.

[0023] The mixing mechanism includes a lifting limit post 6 fixedly connected to the bottom of the lifting limit groove 5, a lifting connecting drive block 7 slidably sleeved on the outside of the lifting limit post 6, a lifting connecting drive post 9 fixedly connected to the upper end of the lifting connecting drive block 7, and a lifting connecting drive disk 10 fixedly connected to the upper end of the lifting connecting drive post 9. A spring 11 is fixedly connected between the lifting connecting drive block 7 and the bottom of the lifting limit groove 5. Multiple sets of drive placement mechanisms are connected to the outside of the lifting connecting drive block 7. A lifting limit hole 8 is opened at the lower end of the lifting connecting drive block 7, and the lifting limit hole 8 is slidably sleeved on the outside of the lifting limit post 6.

[0024] The lifting limit groove 5 provides a vertical sliding track for the lifting connection drive block 7, restricting it to move only up and down along the groove body to avoid movement deviation leading to unstable mixing. At the same time, it plays a role in accommodating and protecting internal components such as the spring 11 and the lifting limit column 6.

[0025] The lifting limit post 6 provides precise guidance for the up and down movement of the lifting connecting drive block 7, preventing it from shaking or tilting during movement. On the other hand, the spring 11 sleeved on its outer side can reset the lifting connecting drive block 7 through its own elastic deformation, making it the core power transmission guide component for the mixing motion.

[0026] The core function of the lifting drive block 7 is to convert the reciprocating motion in the vertical direction into the vertical motion of the rack 13, thereby driving the gear 16 to rotate. It is a key intermediate component for power transmission; at the same time Spring 11 provides stable elastic power for the reciprocating motion of the mixing mechanism, avoiding reliance on complex motor structures to achieve reciprocating motion, simplifying the device structure and reducing energy consumption.

[0027] The drive placement mechanism includes a rack 13 fixedly connected to the outside of the lifting drive block 7, two sets of rotating connecting seats 14 fixedly connected to the upper end of the mixing support base 1, a rotating shaft 15 rotatably connected between the two sets of rotating connecting seats 14, a gear 16 fixedly sleeved on the outside of the rotating shaft 15, and a mounting bracket 17; the drive placement mechanism also includes a test tube placement sleeve 18 fixedly connected to the upper end of the mounting bracket 17, a rubber anti-slip pad 19 fixedly connected to the inner wall of the test tube placement sleeve 18, multiple sets of rubber protrusions fixedly connected to the inner wall of the rubber anti-slip pad 19, and the gear 16 meshing with the rack 13; a spring 11 sleeved on the outside of the lifting limit post 6.

[0028] Among them, the rack 12 meshes with the gear 16, and its core function is to convert the vertical reciprocating motion of the lifting connection drive block 7 into the rotational motion of the gear 16, thereby realizing the conversion of motion form and providing power for the swinging and mixing of the test tube placement sleeve 18.

[0029] The test tube placement sleeve 18 provides a dedicated placement space for the blood collection tubes. Its inner diameter is compatible with commonly used blood collection tube specifications, which can fix the blood collection tubes and prevent them from shaking or colliding during the mixing process. At the same time, it moves synchronously with the swing of the mounting frame 17, which drives the convection of liquid inside the blood collection tubes to achieve mixing.

[0030] The inner wall of the rubber anti-slip pad 19 is provided with multiple sets of rubber protrusions. On the one hand, the high friction of the rubber material enhances the fit between the blood collection tube and the inner wall of the test tube placement sleeve 18, preventing the blood collection tube from moving up and down or rotating during swinging. On the other hand, the elasticity of the rubber material can play a buffering role, avoiding hard collision between the blood collection tube and the inner wall of the test tube placement sleeve 18, which could cause damage. At the same time, the rubber protrusions can further improve the anti-slip effect.

[0031] The working process of this utility model is as follows: 1. Equipment preparation stage Medical staff first hold the carrying handle 3 and carry the device to the blood collection site, such as an ambulance or community clinic. Then, they rotate the sealing protective cover 2 and use the engagement between its lower internal thread and the external thread of the sealing installation ring groove 4 of the mixing support base 1 to remove the sealing protective cover 2 from the mixing support base 1, exposing the internal drive placement mechanism.

[0032] According to the specifications of the blood collection tube, the blood collection tube containing the blood sample and anticoagulant is directly placed into the test tube placement sleeve 18. The rubber anti-slip pad 19 and rubber protrusions on the inner wall of the test tube placement sleeve 18 conform to the outer wall of the blood collection tube through elastic deformation, and use friction to stabilize and fix the blood collection tube, preventing it from loosening during subsequent movement. If there are slight differences in the diameter of the blood collection tube, the elasticity of the rubber anti-slip pad can be adjusted adaptively to ensure compatibility.

[0033] 2. Mixing stage If it is manually driven, medical staff can press the lifting connection drive plate 10 to directly push the lifting connection drive block 7 downward.

[0034] Under pressure, the lifting connection drive block 7 slides downward along the lifting limit post 6, while simultaneously compressing the spring 11 sleeved on the outside of the lifting limit post 6. The spring 11 generates elastic potential energy due to compression. During this process, the rack 13 on the outside of the lifting connection drive block 7 moves downward synchronously with it. Since the rack 13 meshes with the gear 16, the downward movement of the rack 13 drives the gear 16 to rotate clockwise.

[0035] Gear 16 is fixedly sleeved on the outside of rotating shaft 15. Its clockwise rotation drives rotating shaft 15 to rotate synchronously clockwise under the support of two sets of rotating connecting seats 14. This, in turn, drives mounting bracket 17 fixed on the outside of rotating shaft 15 to swing clockwise. Test tube placement sleeve 18 at the upper end of mounting bracket 17 swings clockwise together with mounting bracket 17. The swing angle can be controlled between 15-30° by the design of rack length and gear teeth to ensure mixing effect and avoid blood cell rupture. Blood in blood collection tube and anticoagulant generate convection under the swing action, and are initially mixed.

[0036] When the medical staff releases the pressure, the pressure on the lifting connection drive block 7 disappears, the elastic potential energy stored in the spring 11 is released, and the lifting connection drive block 7 is pushed upward along the lifting limit post 6 to reset to the initial position.

[0037] During the upward reset of the lifting connection drive block 7, the rack 13 moves upward synchronously, driving the meshing gear 16 to rotate counterclockwise, which in turn drives the test tube placement sleeve 18 to swing counterclockwise through the rotating shaft 15 and the mounting bracket 17, causing the liquid in the blood collection tube to convect and mix again; thus, a reciprocating motion of "downward compression-upward reset" is completed, and the test tube placement sleeve 18 achieves a complete swing of "clockwise-counterclockwise".

[0038] Repeat the above steps to make the test tube placement sleeve 18 continuously swing the blood collection tube. The swing frequency can be controlled by manually pressing the frequency at 50-100 rpm. The blood and anticoagulant are fully and evenly mixed under multiple convection actions to avoid anticoagulant deposition or uneven mixing.

[0039] 3. Work completion stage Once the mixture is fully mixed, stop manually pressing. Spring 11 will push the lifting connection drive block 7 back to its initial position, and rack 13, gear 16, rotating shaft 15, mounting bracket 17, and test tube placement sleeve 18 will all return to their initial state.

[0040] Remove the mixed blood collection tube from the test tube placement sleeve 18 and proceed with subsequent testing. If continued use is required, repeat the "device preparation - mixing process". If the device is not used for a long time, clean it, install the sealing protective cover 2 on the mixing support base 1, and carry it to the storage location via the carrying handle 3.
