Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a device for medical detection, separation, and sampling. Background Art

[0002] In medical detection, a centrifuge is a commonly used device mainly for separation and sampling. A medical centrifuge is a commonly used device in medical detection, used for separating serum, plasma, precipitating proteins, or performing urine sediment examinations, etc. The medical centrifuge utilizes the powerful centrifugal force generated by the high-speed rotation of the rotor to force the particles in the liquid to overcome diffusion and accelerate the sedimentation speed, thereby separating substances with different sedimentation coefficients and buoyancy densities in the sample. Its working principle is mainly based on two mechanisms: centrifugal filtration and centrifugal sedimentation.

[0003] In the Chinese patent with the publication number CN105964419A, a medical centrifuge is mentioned, which includes a housing. A touch screen is provided on the side of the housing, and a centrifugal chamber is provided on the top of the housing. The center of the centrifugal chamber is connected to a centrifugal turntable through a motor shaft. A barcode scanning slot is provided beside the centrifugal chamber, and a switch and a USB interface are provided on the side of the housing. When in use, first place the gel card on the centrifugal turntable, place the centrifugal turntable into the centrifugal chamber, touch the touch screen to select the operation mode. After the operation is completed, open the upper cover to take out the gel card, aim the barcode on the gel card at the barcode scanning slot for photographing and barcode scanning and store it in the built-in storage bar, and it can be transmitted through the USB interface, which is convenient for data recording and transmission. And because a heating plate and a temperature sensor are provided, constant-temperature incubation can be achieved.

[0004] The medical centrifuge in the above-mentioned comparative patent includes a housing. A touch screen is provided on the side of the housing, and a centrifugal chamber is provided on the top of the housing. The center of the centrifugal chamber is connected to a centrifugal turntable through a motor shaft. A barcode scanning slot is provided beside the centrifugal chamber, and a switch and a USB interface are provided on the side of the housing. However, for the existing medical centrifuge, the test tube rack of the centrifuge is fixed and cannot swing. The working principle of the centrifuge is to generate centrifugal force through rotation, so that the sample is separated under the action of force in the test tube. During the centrifugation process, the test tube and the test tube rack will be subjected to an outward centrifugal force. If the test tube rack is fixed, the test tube may break or shift due to uneven force. At the same time, the test tubes inside the device need to be taken out one by one, which is prone to bump damage. The height of the centrifuge is fixed, making it difficult to be compatible with the placement and removal. Summary of the Invention

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Example 1:

[0033] Please refer to Figures 1 - 6 As shown in the figure, a medical detection separation and sampling device includes:

[0034] The device main body 1; the device main body 1 includes a slide rail 11, and one end of the slide rail 11 is slidably connected to the machine cover 12;

[0035] A protection mechanism 3 is arranged inside the device main body 1. The protection mechanism 3 includes an inner disk 31, a second driving member 32 is installed at the upper end of the inner disk 31, and a tube placing disk 33 is arranged at the upper end of the second driving member 32.

[0036] Furthermore, an insertion groove 34 is formed inside the tube placing disk 33, a rotating member 35 is inserted into the insertion groove 34, and a sampling test tube 36 is inserted into the rotating member 35.

[0037] In summary, the outer surface of the rotating member 35 is rotationally matched with the inner wall of the tube placing disk 33, and the outer surface of the sampling test tube 36 is attached to the inner wall of the rotating member 35.

[0038] Specifically, in the carefully designed experimental device, the device main body 1 is the core part. A machine cover 12 is ingeniously configured at its upper end. This design not only gives the device an aesthetic appearance, but more importantly, it realizes convenient operation. The machine cover 12 is tightly combined with the device main body 1 in a sliding opening and closing manner. The user can easily open or close the machine cover 12 with a gentle push or pull, greatly improving the efficiency and smoothness of the experimental operation. The protection mechanism 3 is installed inside the device main body 1. By installing the second driving member 32 at the upper end of the inner disk 31 and starting the second driving member 32 to drive the tube placing disk 33 to rotate, an insertion groove 34 is formed inside the tube placing disk 33. Since the rotating member 35 is inserted into the tube placing disk 33, the sampling test tube 36 inside the rotating member 35 swings inside the tube placing disk 33. The rotatable rotating member 35 can better adapt to this mechanical change and disperse and balance the forces received through swinging, thereby protecting the sampling test tube 36 from damage. A series of carefully formed insertion grooves 34 are evenly distributed inside it. These grooves are specially designed to accommodate the sampling test tubes 36, ensuring that each sampling test tube 36 can be stably and safely supported. More ingeniously, a rotatable rotating member 35 is inserted into each insertion groove 34. This design allows the sampling test tube 36 installed inside the rotating member 35 to swing slightly when the tube placing disk 33 rotates.

[0039] In addition, a disassembly and assembly mechanism 4 is installed between the second driving member 32 and the tube placing disk 33, which is convenient for lifting multiple groups of sampling test tubes 36 inside the tube placing disk 33 from the inside of the device main body 1.

[0040] Example 2:

[0041] Reference Figures 1 - 6 As shown, the disassembly mechanism 4 is arranged inside the protection mechanism 3. The disassembly mechanism 4 includes a sleeve block 41. The upper end of the second driving member 32 is installed with an insertion block 42. Both ends of the insertion block 42 are movably connected to elastic members 43. The inner wall of the sleeve block 41 is fitted with the outer surface of the insertion block 42. The outer surface of the elastic block 44 is fitted with the inner groove of the sleeve block 41.

[0042] As can be seen from the above, between the second driving member 32 and the catheter placement tray 33, the designer cleverly incorporated an easily operable disassembly mechanism 4. This design greatly improves the flexibility and maintenance convenience of the device. Specifically, the disassembly mechanism 4 mainly consists of key components such as a sleeve block 41, an insertion block 42, elastic members 43, elastic blocks 44, snap buttons 45, and a reset member 46. The insertion block 42 is precisely inserted into the sleeve block 41 at the lower end of the catheter placement tray 33, forming a stable connection foundation. The elastic members 43, with their unique elastic properties, cleverly drive the elastic blocks 44 to be clamped at specific positions in the sleeve block 41, ensuring the stability and reliability of the catheter placement tray 33 during rotation. A snap button 45 is inserted inside the sleeve block 41. When wanting to disassemble the entire elastic block 44, press the snap button 45 inward to make the elastic block 44 contract through the elastic members 43, and then the catheter placement tray 33 at the upper end of the sleeve block 41 can be disassembled, facilitating the unified lifting of multiple sampling test tubes 36 inside the catheter placement tray 33 from the inside of the device main body 1. The reset member 46 is sleeved outside the snap button 45 to facilitate the quick reset of the snap button 45. The presence of the reset member 46 not only ensures that the snap button 45 can quickly reset after the disassembly operation, preparing for the next use, but also adds a charm of both delicacy and practicality to the entire disassembly mechanism 4. Therefore, when the user needs to unify lift multiple sampling test tubes 36 inside the catheter placement tray 33 from the inside of the device main body 1, this goal can be easily achieved with just a few simple operations, greatly improving the convenience and efficiency of experimental operations.

[0043] Embodiment 3:

[0044] Reference Figures 1 - 6As shown in the figure, there is a picking mechanism 2. The picking mechanism 2 is arranged at the lower end of the device main body 1. The picking mechanism 2 includes a chassis 21. A first driving member 22 is installed at the upper end of the chassis 21. One end of the first driving member 22 is drivingly connected to a transverse tooth column 23. The upper end of the transverse tooth column 23 is drivingly connected to a first rotating tooth 24. One end of the first rotating tooth 24 is connected to a connecting column 25. One end of the connecting column 25 is connected to a second rotating tooth 26. A guide plate 27 is installed at the upper end of the chassis 21. A vertical tooth column 207 is installed at the lower end of the device main body 1. Sliders 28 are installed at both ends of the device main body 1. A chute 29 is formed on the inner wall of the guide plate 27. The outer surface of the first rotating tooth 24 is engaged with the upper end of the transverse tooth column 23. The outer surface of the second rotating tooth 26 is engaged with one end of the vertical tooth column 207. Two groups of sliders 28 are installed. The outer surface of the slider 28 is slidably matched with the chute 29.

[0045] Under the design concept of pursuing the ultimate user experience, an innovative and practical picking mechanism 2 is given to the lower end of the device main body 1. This design skillfully combines mechanical principles and ergonomics, aiming to meet the usage needs of staff with different heights. The core composition of the picking mechanism 2 includes a stable chassis 21, inside which a powerful first driving member 22 is carefully installed. When the first driving member 22 is activated, it drives a transverse tooth column 23 to perform precise lateral movement. This action is like a linkage device in precision machinery, instantly activating the vitality of the entire picking mechanism 2.

[0046] The movement of the transverse tooth column 23 then drives the closely connected first rotating tooth 24 to start rotating. The first rotating tooth 24 is seamlessly connected to the connecting column 25 at the other end through its precise tooth design. This design ensures the high efficiency and stability of power transmission. As the first rotating tooth 24 continues to rotate, the second rotating tooth 26 engaged with it also starts to rotate. This series of gear transmissions is like the internal mechanism of a precision clock, and every action is full of strength and beauty.

[0047] Especially importantly, the rotation of the second rotating tooth 26 is finally perfectly engaged with the vertical tooth column 207. The vertical tooth column 207, as the "elevator" in the entire picking mechanism 2, starts to drive the device main body 1 to perform smooth lifting adjustment after receiving the power from the second rotating tooth 26. This design not only realizes the free adjustment of the height of the device main body 1, but also endows the device with flexibility and compatibility, ensuring that no matter how tall the staff is, they can easily place the sampling test tube 36 inside the device main body 1, greatly reducing the accidental bumps caused by improper height.

[0048] To further enhance the stability and safety of the device main body 1 during the lifting process, the designer cleverly installed sliders 28 at both ends of the device main body 1. These sliders 28 can precisely slide in the chutes 29 on the inner wall of the guide plate 27, just like a pair of accurate guide rails, providing solid support and guidance for the height adjustment of the device main body 1. This design not only improves the overall stability of the device, but also makes each lifting operation appear smooth and natural.

[0049] In summary, the introduction of the picking mechanism 2 not only greatly improves the compatibility and practicality of the device main body 1, but also ensures that each staff member can use the device in the most comfortable and safe way through a series of delicate design details, thus greatly improving the efficiency and safety of the experimental operation.
