Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a clinical medical testing oscillation device. Background Technology

[0002] The laboratory department serves as a bridge between clinical and basic medicine, encompassing sub-disciplines such as clinical chemistry, clinical microbiology, clinical immunology, hematology, body fluid analysis, and transfusion medicine. Test tubes are commonly used instruments in chemistry and medicine, serving as reaction containers for small amounts of reagents. In medical laboratories, the application of test tubes is indispensable. Many liquid test samples require manual shaking of the sample test tube by laboratory personnel to mix the sample with the reagents.

[0003] A search revealed a patent with publication number CN120586722A, which proposes an oscillation device for clinical medical testing, relating to the field of medical equipment. This oscillation device for clinical medical testing, because both ends of the rotating rod are rotatably engaged, can be pulled and pushed with the oscillation rod to complete the shaking of the rotating column. Due to the rotatable connection between the rotating column and the top plate, the oscillator at the top of the rotating column can be shaken. This structure achieves vibration and improves the oscillation effect.

[0004] The existing technology uses a fixed, integrated design for the support unit, which cannot be flexibly adjusted according to the number of samples tested. Even if only a few samples need to be oscillated, the entire large equipment must be used, which will waste electricity when processing a small number of samples. At the same time, since all moving parts need to participate in the entire process every time, the fatigue wear of the equipment is accelerated and the service life is shortened. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the problems existing in the above and / or existing clinical medical testing oscillation devices, the present invention is proposed.

[0007] To address the aforementioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A clinical medical testing oscillation device includes a housing with a cover, a movable frame slidably mounted inside the housing, a plurality of placement modules on the movable frame, and the placement modules being slidably mounted on the movable frame via a plurality of insert rods, and an oscillation mechanism inside the housing.

[0008] As a preferred embodiment of the clinical medical testing oscillation device of the present invention, the placement module includes a placement frame and a contact plate connected vertically, and both the placement frame and the contact plate are configured as elastic structures.

[0009] As a preferred embodiment of the clinical medical testing oscillation device of the present invention, the oscillation mechanism includes a rotating frame rotatably installed in a housing, a contact frame slidably installed in the rotating frame, a first contact block evenly distributed on the inner wall of the contact frame, and a protrusion evenly distributed on the outer wall of the contact plate.

[0010] As a preferred embodiment of the clinical medical testing oscillation device described in this invention, a second contact block is also provided on the inner wall of the contact frame in a uniformly distributed manner.

[0011] As a preferred embodiment of the clinical medical testing oscillation device of the present invention, the outer wall of the contact frame is provided with uniformly distributed insert plates, and the insert plates are magnetically compatible with the rotating frame, and the outer wall of the outer shell is provided with an adjustment port.

[0012] As a preferred embodiment of the clinical medical testing oscillation device of the present invention, a motor is provided inside the housing, a support block is provided inside the housing, a second gear is rotatably mounted on the outer wall of the support block, and the second gear is connected to the rotating frame through several connecting plates. A first rotating shaft is rotatably mounted inside the housing and is connected to the output end of the motor. A first gear is provided at one end of the first rotating shaft, and the first gear meshes with the second gear.

[0013] As a preferred embodiment of the clinical medical testing oscillation device of the present invention, a second rotating shaft is inserted and rotatably mounted in the support block, and the second rotating shaft is connected to the first rotating shaft through a pulley group. A rotating block is provided on the second rotating shaft, and a transition block is provided on the rotating block. A connecting block is provided in the movable frame, and a top rod is provided at the bottom of the connecting block, and the top rod abuts against the transition block.

[0014] As a preferred embodiment of the clinical medical testing oscillation device described in this invention, the transition block is a smooth, spirally upward-pointing arc surface, and a cross-section is provided on one side.

[0015] In a preferred embodiment of the clinical medical testing oscillation device of the present invention, an insert block is rotatably installed inside the rotating block, a second guide rod is inserted and slidably installed inside the connecting block, and the second guide rod is disposed on the top surface of the insert block, and a spring is sleeved on the outside of the insert block.

[0016] As a preferred embodiment of the clinical medical testing oscillation device of the present invention, the bottom of the connecting block is symmetrically provided with uniformly distributed first guide rods, and the first guide rods are inserted into the plug block and slidably installed. The outer wall of the first guide rod is sleeved with uniformly distributed elastic rings, and the top surface of the plug block is provided with uniformly distributed contact sleeves corresponding to the first guide rods.

[0017] Compared with the prior art, the beneficial effects of the present invention are: Since the placement module is detachably connected to the movable frame via a plug, unused modules can be removed, which reduces the motion load on the equipment, reduces energy waste, and avoids fatigue wear caused by idle parts participating in the motion.

By toggling the contact frame up and down to switch between the first and second contact blocks, the mixing requirements of samples with different viscosities can be accommodated, making the oscillation effect flexible and adjustable without the need to change equipment or adjust motor parameters. The combination of the oscillation effect created by the impact of the contact block and the up-and-down shaking created by the cross-section of the transition block, along with the downward jerking sensation brought about by the contact between the elastic ring and the contact sleeve, forms a multi-layered mixing effect, which can effectively break up the sample stratification, making the mixing more thorough and improving the sample mixing effect.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. Example

[0023] Please refer to the following: Figures 1 to 6 This embodiment provides a clinical medical testing oscillation device for mixing liquid samples and reagents in clinical medical testing. It addresses the problems of energy waste and accelerated fatigue wear caused by the fixed, integrated design of existing devices with small sample volumes, and the constant involvement of moving parts. Through a detachable placement module, dual oscillation coordination, and adjustable oscillation intensity, it achieves efficient sample mixing while reducing energy consumption and equipment wear. The device includes a shell 1, a cap 3, a movable frame 4, a placement module 5, an oscillation mechanism 7, and a drive component. The shell 1 serves as a sealed oscillation space and structural carrier; the cap 3 can be opened and closed for easy sample placement and removal; the movable frame 4 carries the placement module 5, which is used to fix test tubes; the oscillation mechanism 7 achieves multi-dimensional oscillation; and the drive component provides power for the overall operation.

[0024] Specifically, the outer shell 1 is a hollow structure with an open top. The cover 3 is closed on the opening of the outer shell 1. A movable frame 4 is slidably installed in the vertical direction inside the outer shell 1. The movable frame 4 is frame-shaped, and several placement modules 5 are connected inside it through several insertion rods 21. The insertion rods 21 are inserted into the movable frame 4 and the placement modules 5 in the horizontal direction, so that the placement modules 5 can be removed along the insertion rods 21. When only a small number of samples need to be processed, the placement modules 5 without test tubes can be removed from the movable frame 4. This can avoid unnecessary frictional wear caused by the movement of idle modules with the movable frame 4, and at the same time reduce the overall motion load of the equipment and reduce power consumption.

[0025] The placement module 5 includes a placement frame 19 and a contact plate 18 connected vertically. Both are designed as elastic structures. The internal space of the placement frame 19 is adapted to the outer diameter of the test tube, and the test tube can be embedded in the placement frame 19. The elastic structure can not only tightly fix the test tube and prevent it from shifting during oscillation, but also buffer the impact force of oscillation. Multiple evenly distributed protrusions 20 are integrally formed on the outer wall of the contact plate 18. The protrusions 20 are used to cooperate with the contact block of the oscillation mechanism 7 to transmit the oscillation force to the placement frame 19 and the test tube, so as to achieve full mixing of the sample in the test tube.

[0026] The oscillation mechanism 7 includes a rotating frame 17 and a contact frame 23. The rotating frame 17 is rotatably mounted inside the housing 1 in the horizontal direction. The contact frame 23 is slidably mounted on its inner sidewall in the vertical direction. Two sets of contact blocks, a first contact block 24 and a second contact block 25, are integrally formed on the inner wall of the contact frame 23. The distribution density of the second contact block 25 is greater than that of the first contact block 24. Several insert plates 22 are fixedly arranged on the outer wall of the contact frame 23. The insert plates 22 have a magnetic fit relationship with the inner sidewall of the rotating frame 17. When the contact frame 23 is moved in the vertical direction, the first contact block 24 or the second contact block 25 can be switched to correspond with the protrusion 20 of the placement module 5. The magnetic fit can fix the contact frame 23 in the switched position and prevent displacement during oscillation.

[0027] When the rotating frame 17 rotates, it drives the contact frame 23 to rotate synchronously. The contact blocks on the inner wall of the contact frame 23 will periodically impact the protrusion 20. The protrusion 20 transmits the impact force to the elastic contact plate 18 and the placement frame 19, thereby causing the sample in the test tube to oscillate in the horizontal direction. When the second contact block 25 is selected, because the contact block density is higher, the number of times it impacts the protrusion 20 per unit time is more, and the oscillation intensity is stronger. It can be adapted to scenarios with high sample viscosity and need for vigorous mixing. Conversely, the first contact block 24 is used to achieve flexible adjustment of the oscillation effect.

[0028] An adjustment port 2 is provided on the outer wall of the housing 1. The adjustment port 2 corresponds to the position of the contact frame 23. The operator can insert his finger through the adjustment port 2 and move the contact frame 23 in the vertical direction to switch the contact block. The operation is convenient and does not require any additional tools.

[0029] The housing 1 contains a motor 8 and a support block 13. The support block 13 extends vertically and a second gear 12 is rotatably mounted on its outer wall. The second gear 12 is fixedly connected to the outer wall of the rotating frame 17 through several connecting plates 16, so that the rotation of the second gear 12 can drive the rotating frame 17 to rotate synchronously. The housing 1 also contains a first rotating shaft 10. One end of the first rotating shaft 10 is fixedly connected to the output end of the motor 8, and the other end is fixedly fitted with a first gear 11. The first gear 11 meshes with the second gear 12. The first gear 11 is a large gear structure and the second gear 12 is a small gear structure. The transmission method of the large gear driving the small gear can amplify the speed of the motor 8, so that the rotating frame 17 can obtain a higher rotation speed. The frequency of the contact block hitting the protrusion 20 per unit time increases, further enhancing the horizontal oscillation effect and improving the sample mixing efficiency.

[0030] A second rotating shaft 14 is inserted vertically and rotatably installed inside the support block 13. The second rotating shaft 14 is connected to the first rotating shaft 10 through a pulley set 9. When the motor 8 starts, the first rotating shaft 10 drives the second rotating shaft 14 to rotate synchronously through the pulley set 9. A rotating block 15 is fixedly installed at the top of the second rotating shaft 14. A transition block 32 is fixedly installed on the top surface of the rotating block 15. The transition block 32 is a smooth spiral upward arc surface, and one side of the arc surface has a cross section. A connecting block 6 is fixedly installed on the bottom surface of the movable frame 4. A top rod 33 is fixedly installed vertically at the bottom of the connecting block 6. The bottom end of the top rod 33 is in close contact with the arc surface of the transition block 32. When the second rotating shaft 14 drives the rotating block 15 to rotate, the spiral arc surface of the transition block 32 will gradually lift the top rod 33, causing the top rod 33 to drive the connecting block 6 and the movable frame 4 to rise in the vertical direction. When the top rod 33 rotates with the rotating block 15 to the cross section of the transition block 32, the top rod 33, which loses the support of the arc surface, will drive the movable frame 4 to suddenly drop, forming an impact oscillation in the up and down direction. Combined with the horizontal oscillation, it achieves a double oscillation effect, and the sample is mixed more thoroughly.

[0031] A second guide rod 31 is inserted vertically and slidably installed inside the connecting block 6. An insert block 30 is rotatably installed inside the rotating block 15. The bottom end of the second guide rod 31 is fixedly connected to the top surface of the insert block 30. A spring 26 is sleeved on the outside of the insert block 30. The two ends of the spring 26 abut against the inner wall of the rotating block 15 and the outer wall of the insert block 30, respectively. Several first guide rods 27 are also symmetrically fixedly installed at the bottom of the connecting block 6. The first guide rods 27 are inserted vertically into the insert block 30 and slide to fit the insert block 30. Several elastic rings 28 are sleeved on the outer wall of the first guide rods 27. A contact sleeve 29 corresponding to the first guide rods 27 is fixedly installed on the top surface of the insert block 30. The inner wall of the contact sleeve 29 fits the elastic ring 28. When the movable frame 4 descends, the first guide rod 27 moves down with the connecting block 6, and the elastic ring 28 intermittently presses against the inner wall of the contact sleeve 29. The contact sleeve 29 generates a slight blocking force on the elastic ring 28, making the descent of the movable frame 4 feel jerky. This jerky oscillation further breaks the static stratification of the sample and improves the mixing uniformity. At the same time, the elastic restoring force of the spring 26 can buffer the impact force of the insert block 30 and prevent the components from being damaged by rigid collision.

[0032] In actual clinical medical testing scenarios, if it is necessary to mix 3 test tubes, the operator first opens the cap 3, inserts the 3 test tubes containing the samples into the placement frames 19 of the 3 placement modules 5 respectively, removes the remaining unused placement modules 5 from the movable frame 4 along the insertion rod 21, and, according to the sample viscosity, moves the contact frame 23 through the adjustment port 2 to select the first contact block 24 or the second contact block 25. The magnetic adapter restricts the contact frame 23 to a fixed position, and the motor 8 is started. The motor 8 drives the first rotating shaft 10 to rotate, and the first gear 11 meshes. The second gear 12 accelerates the rotation, and the connecting plate 16 drives the rotating frame 17 and the contact frame 23 to rotate. The contact block periodically impacts the protrusion 20. The elastic contact plate 18 and the placement frame 19 cause the test tube to oscillate horizontally. At the same time, the first rotating shaft 10 drives the second rotating shaft 14 to rotate through the pulley group 9. The transition block 32 lifts the top rod 33 to raise the movable frame 4. The cross-section suddenly drops. Combined with the jerking action of the first guide rod 27 and the contact sleeve 29, double oscillation is achieved. After mixing is completed, the motor is turned off, the cap 3 is opened and the test tube is taken out.

[0033] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
