Abstract
Description
Technical Field
[0001] This invention relates to blood collection technology, specifically to a vibration device for collecting anticoagulant blood samples. Background Technology
[0002] Hospitals require blood samples for diagnosing many diseases. Blood collection can screen for numerous illnesses in the body. In clinical medical testing, the quality of blood samples is paramount to ensuring accurate test results. Collected blood samples must be immediately and thoroughly mixed with anticoagulants (such as EDTA, sodium citrate, heparin, etc.) to prevent clotting or the formation of microclots. Clotting will directly render the sample unusable, delaying diagnosis, increasing patient suffering and medical costs associated with repeat blood draws, and potentially affecting clinical decisions due to the inability to detect key indicators.
[0003] Chinese patent CN222093116U discloses a blood anticoagulation oscillation device for blood collection. This device, through the coordinated use of a mixing component, mechanical grippers, a camera, and a control device, automatically inverts the collection tubes after blood sample collection, causing the blood sample to oscillate and mix thoroughly. After mixing, it works with a first and second moving component to automatically classify and store the collection tubes according to the color markings on the tubes, facilitating subsequent testing. This convenient design avoids manual errors that could affect test results. A sliding plate, connecting plate, baffle, and magnetic strip work together to limit the movement of the storage box. When the storage box is full, it and the collection tubes inside are removed for testing. The storage box can be replaced without interrupting the mixing process, preventing any impact on collection efficiency.
[0004] Existing equipment is prone to forgetting, insufficient number of times, or insufficient force during use, and it cannot set the optimal processing conditions for different types of samples. This can lead to blood clotting or the formation of micro-clots in the collected blood samples. At the same time, the samples cannot be accurately held in the predetermined position during the experiment, causing the whole sample to shift or tilt during shaking, which makes it susceptible to the influence of external forces during the shaking process. Therefore, an anti-clotting blood sample collection shaking device was developed. Summary of the Invention

[0041] Example: Please refer to Figures 1-9 A vibration device for collecting anticoagulant blood samples includes a base 1, which constitutes the main body of the device.
[0042] Furthermore, the locking mechanism 3, which is assembled at the upper end of the movable mechanism 2, is used to generate a trigger signal when the sample body is inserted into place; wherein, the locking mechanism 3 includes a locking plate 31 that is engaged with the movable mechanism 2, a protective cylinder 311 is slidably disposed on the outer surface of the locking plate 31, a support block 32 is fixedly disposed on the inner wall of the protective cylinder 311, and a power cylinder 321 is fixedly disposed at the end of the support block 32.
[0043] In this embodiment, the end of the locking plate 31 is provided with bolts or other fixing components to fix the locking plate 31 on the movable mechanism 2 and to swing with the movable mechanism 2.
[0044] The power cylinder 321 is supported by the support block 32, thereby stabilizing the power cylinder 321 in the inner cavity of the protective cylinder 311 and ensuring the stability of the rotating block 33. At the same time, a limiting block is provided on the inner wall of the power cylinder 321, and the outer surface of the limiting block is slidably connected to the inner wall of the arc groove 331.
[0045] Furthermore, a rotating block 33 is rotatably provided on the inner wall of the power cylinder 321, and an arc-shaped groove 331 is provided on the outer surface of the rotating block 33.
[0046] Specifically, a squeezing plate is rotatably provided at the upper end of the power cylinder 321 to support the sample. At the same time, it is slidably connected to the limiting block through the arc groove 331 opened on the outer surface of the power cylinder 321, so that when the power cylinder 321 moves downward, the power cylinder 321 rotates along the trajectory of the arc groove 331.
[0047] Furthermore, a pressing block 34 is rotatably fitted into the inner wall of the rotating block 33, a locking block 341 is slidably provided on the outer surface of the pressing block 34, and a locking block 342 is rotatably provided at the middle position of the upper end of the locking plate 31. The outer surface of the locking block 342 is slidably connected to the ends of the pressing block 34 and the locking block 341, respectively.
[0048] Specifically, since the pressing block 34 is fitted and rotatably disposed on the inner wall of the rotating block 33, when the rotating block 33 moves, it drives the pressing block 34 to move downward.
[0049] The lower end of the pressing block 34 is provided with two pressing rods, and a guide groove is provided between the two pressing rods. The lower end of the locking block 341 is symmetrically provided with locking rods, and the outer surface of the locking rods is slidably connected to the inner wall of the guide groove.
[0050] The outer surface of the locking block 342 has two locking grooves, one high and one low, which are slidably connected to the outer surfaces of the locking rod and the pressing rod, respectively. The inner wall of the locking block 342 is rotatably connected to the inner wall of the pressing block 34 through a fixed rod, so that when the pressing block 34 moves, it drives the locking block 342 to move synchronously.
[0051] A spring is fitted on the outer surface of the pressing block 34. One end of the spring is connected to the end of the pressing block 34, and the other end is connected to the end of the locking block 341. The spring tightly presses the locking rod against the inner wall of the two locking grooves. The pressing rod squeezes the locking block 342 to rotate, thereby adjusting the locking position of the locking rod and the locking groove, generating a trigger signal, realizing the detection of the sample body being inserted into place, and causing the pressing block 34 to press up and down to lock.
[0052] The outer surface of the locking block 341 is fixedly connected to the inner wall of the protective cylinder 311 through the positioning plate, so that the locking block 341 is stably in the current position.
[0053] Furthermore, a turntable 36 is fixedly provided at the end of the rotating block 33, and multiple sets of connecting rods 35 are evenly slidably provided at the lower end of the turntable 36. The other end of the connecting rod 35 is connected to the upper end of the locking plate 31. An elastic element 351 is sleeved on the outer surface of the connecting rod 35, and the two ends of the elastic element 351 are respectively connected to the two ends of the connecting rod 35.
[0054] Specifically, the connecting rod 35 is a telescopic rod or other component with telescopic function, and the two ends of the connecting rod 35 are supported by the elastic element 351, which is a spring or other elastic component.
[0055] When the turntable 36 moves downward, it presses against the connecting rod 35. After the force stops, the turntable 36 is restored to its initial position by the force of the elastic element 351. At the same time, the upper end of the connecting rod 35 is slidably connected to the lower end of the turntable 36, so that the turntable 36 will not be disturbed when it rotates.
[0056] Furthermore, a ring 361 is fixedly provided on the inner wall of the turntable 36, and multiple sets of push rods 37 are evenly rotatably provided at the end of the ring 361, and a clamping plate 371 is rotatably provided at the end of the push rod 37.
[0057] Specifically, when the turntable 36 rotates and moves synchronously with the rotating block 33, it drives the ring 361 fixedly installed on its inner wall to rotate, which in turn drives the push rod 37 rotatably installed at its end to move. Since the end of the push rod 37 is rotatably equipped with a clamping plate 371, the clamping plate 371 moves with the push rod 37.
[0058] Furthermore, a support plate 38 is rotatably provided at the end of the turntable 36, and a support groove 381 is provided at the lower end of the support plate 38. The inner wall of the support groove 381 is slidably connected to the outer surface of the ring 361, while the end of the clamping plate 371 is rotatably connected to the lower end of the support plate 38.
[0059] Specifically, the ring 361 is constrained by the support groove 381 on the support plate 38, so that the ring 361 moves along the inner wall of the support groove 381 and supports the end of the clamping plate 371. After being subjected to force, the clamping plate 371 rotates around the connection with the support plate 38, thereby locking the sample in the middle position of the support plate 38. The outer surface of the clamping plate 371 is provided with a flexible material to protect the outer surface of the sample.
[0060] Furthermore, a docking block 39 is fixedly provided on the outer surface of the support plate 38, and the lower end of the docking block 39 is engaged with the upper end of the protective cylinder 311.
[0061] Specifically, the inner wall of the upper end of the docking block 39 is arc-shaped, which is used to quickly dock the sample and at the same time perform preliminary calibration of the sample to ensure that the sample can smoothly enter the locking mechanism 3.
[0062] Furthermore, the active mechanism 2, which is assembled on the upper end of the base 1, is used to perform uniform automatic reciprocating oscillation on the sample; the active mechanism 2 includes a fixed plate 21 that is snapped into the base 1, a drive rod 22 is rotatably provided on the upper end of the fixed plate 21, and a drive cylinder 23 is rotatably provided on the outer surface of the drive rod 22.
[0063] In this embodiment, the end of the drive rod 22 is provided with a device with power output such as a motor, and the outer surface of the drive cylinder 23 is engaged with a device with power output such as a motor and connected to an external control device, thereby enabling the drive rod 22 and the drive cylinder 23 to rotate coaxially. At the same time, transmission gears are fixedly provided on the outer surfaces of the upper ends of both the drive rod 22 and the drive cylinder 23.
[0064] Furthermore, a semi-circular plate 24 is fixedly installed at the upper end of the fixed plate 21, and a semi-circular plate 25 is snapped onto the end of the semi-circular plate 24; a ring gear 26 is fixedly installed on the inner wall of the semi-circular plate 25, and the outer surface of the ring gear 26 meshes with the outer surface of the drive cylinder 23.
[0065] Specifically, when the drive cylinder 23 rotates, it drives the ring gear 26 that meshes with it to rotate. Since the ring gear 26 is fixedly installed on the inner wall of the semicircular plate 25, it drives the semicircular plate 25 to rotate synchronously.
[0066] Furthermore, a limiting rod 27 is rotatably provided on the inner wall of the second semicircular plate 25, and a mating gear 271 is symmetrically fixed on the outer surface of the limiting rod 27. At the same time, the other end of the limiting rod 27 is rotatably connected to the inner wall of the first semicircular plate 24. The outer surface of the mating gear 271 meshes with the outer surface of the drive rod 22.
[0067] Specifically, the first semicircular plate 24 and the second semicircular plate 25 are connected together by the limiting rod 27. At the same time, the mating gear 271 fixed on its outer surface meshes with the outer surface of the drive rod 22, thereby driving the entire limiting rod 27 to rotate.
[0068] Furthermore, a power plate 28 is rotatably mounted on the inner wall of the second semicircular plate 25. The outer surface of the power plate 28 meshes with the outer surface of another mating gear 271, and the end of the power plate 28 extends through and to the outside of the second semicircular plate 25. A support plate 29 is fixedly mounted on the end of the power plate 28, and the end of the support plate 29 engages with the end of the locking plate 31.
[0069] Specifically, when the limiting rod 27 rotates, it works with the docking gear 271 to drive the power plate 28 to rotate, which in turn drives the support plate 29 fixed on the power plate 28 to rotate. The end of the support plate 29 is provided with multiple sets of through holes, which limit the locking mechanism 3 and make it stable on the support plate 29.
[0070] The control device can choose a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption.
[0071] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
