Description

Technical Field

[0001] The present invention relates to the technical field of centrifugal equipment, and specifically to a centrifugal equipment for use in a hospital laboratory. Background Art

[0002] The centrifugal equipment for use in a hospital laboratory is an important medical instrument. It generally has a box-like appearance, a sturdy main body, and a rotor inside that can rotate at high speed. The rotation speed is accurate and adjustable, capable of generating a strong centrifugal force. The operation panel is simple and intuitive, and parameters such as time and rotation speed can be set. It is made of high-quality materials, easy to clean and disinfect. During the inspection process, it can effectively separate different components in samples such as blood and urine, providing a reliable basis for subsequent accurate detection, and greatly improving the inspection efficiency and quality.

[0003] The existing Chinese patent with the publication number CN218531345U discloses a centrifugal equipment for use in a hospital laboratory, including a box body. A box cover is installed on the outer wall of one side of the box body near the top through a hinge, and two buckles are installed on the outer wall of one side of the box cover near the bottom through bolts. Two latches are installed on the outer wall of one side of the box body near the top through bolts, and one end of the latch is clamped inside the buckle. A storage groove is opened on the outer wall of one side of the box cover, and a curtain cloth is installed inside the storage groove through bolts. A substrate is installed inside the box body through bolts, and a first loading plate is embedded inside the substrate. When carrying this equipment, the structure composed of the box body, box cover, etc. and the handle can reduce the difficulty for medical staff to carry.

[0034] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0035] Combined with Figures 1 - 5 , a centrifugal device for laboratory tests in a hospital laboratory, comprising a centrifuge body 1, a box cover 11 is hinged on the upper surface of the centrifuge body 1, a separation mechanism 3 for centrifuging reagents is arranged inside the centrifuge body 1, and an auxiliary cover assembly 2 for preventing the centrifuge tube from slipping off is arranged on the upper surface of the separation mechanism 3;

[0036] The separating mechanism 3 includes a sleeve 32 disposed inside the centrifuge body 1. A motor is provided inside the centrifuge body 1. The output end of the motor is fixedly connected to a rotating shaft. One end of the rotating shaft is fixedly connected to the bottom surface of the sleeve 32. A separating cylinder 31 is fixedly connected to the inner wall of the sleeve 32. An arc-shaped ring plate 33 is fixedly connected to the upper surface of the separating cylinder 31. A placement frame 311 is arranged inside the separating cylinder 31. There are a total of eight groups of the placement frames 311, and the eight groups of the placement frames 311 are symmetrically arranged in pairs. A partition ring assembly 34 is rotatably connected inside the separating cylinder 31. The inside of the placement frame 311 is divided into a placement groove A313 and a placement groove B3131 by the partition ring assembly 34. The placement groove B3131 is closer to the center of the separating cylinder 31 and its inner wall inclines downward toward the outside of the separating cylinder 31. An air storage groove 315 is formed inside the placement frame 311. A soft pad pressing plate 314 is slidably connected inside the air storage groove 315. An air guiding groove 316 is formed on the inner wall of the air storage groove 315. An airbag is arranged inside the placement frame 311, and the airbag is communicated with the air guiding groove 316. A buffer pad A312 is fixedly connected to the outside of the airbag. There are two groups of the air guiding groove 316 and the airbag, and the two groups of the air guiding groove 316 and the airbag are symmetrically arranged. A spring rod 317 is fixedly connected to the bottom surface of the soft pad pressing plate 314. A fixing plate 318 is fixedly connected to the inner wall of the air storage groove 315. The spring rod 317 penetrates through the fixing plate 318. A connecting inclined block 37 is fixedly connected to the bottom surface of the fixing plate 318. A balancing component 38 is fixedly connected to the bottom surface of the connecting inclined block 37. A liquid storage box 39 is fixedly connected to the inner wall of the centrifuge body 1. The balancing component 38 penetrates through the liquid storage box 39. A balancing component 35 is arranged between the corresponding two groups of the connecting inclined blocks 37. A liquid storage tray 5 is fixedly connected between the corresponding two groups of the liquid storage boxes 39. The liquid storage box 39 and the liquid storage tray 5 are internally communicated and filled with coolant. A liquid discharging component 4 for discharging the coolant inside the connecting inclined block 37 is fixedly connected to the bottom surface of the liquid storage box 39. When centrifuging the reagent, the centrifuge tube is placed inside the placement groove A313. Under the action of the gravity of the centrifuge tube, the soft pad pressing plate 314 is driven to press down, so that the spring rod 317 drives the connecting inclined block 37 to press down. By pressing down, the balancing component 35 is driven to move toward the corresponding end, driving the other connecting inclined block 37 to move upward. The balancing component 38 below the connecting inclined block 37 moves upward. The coolant inside the liquid storage box 39 is made to flow into the balancing component 38 by using the balancing component 38, so as to increase the weight inside the balancing component 38, realizing automatic balancing. As the weight of the balancing component 38 increases, the connecting inclined block 37 rises again to reach balance. Then, the auxiliary cover assembly 2 is inserted and the partition ring assembly 34 is rotated, so that the centrifuge tube moves from the placement groove A313 to the placement groove B3131. Then the motor is started to complete the centrifugation operation. During the centrifugation process, the centrifuge tube is inclined and pressed down under the action of the centrifugal force, driving the soft pad pressing plate 314 to press down further, and further squeezing the air inside the air storage groove 315, so that the airbag bulges, and the buffer pad A312 is used to fit the centrifuge tube more stably to ensure the clamping effect.

[0037] The present invention will be further described below in conjunction with embodiments.

[0038] Please refer to Figures 1 - 13 , the balancing assembly 35 includes a horizontal inclined block 351. There are two groups of the horizontal inclined blocks 351 in total. A connecting long plate 354 is fixedly connected between the two groups of the horizontal inclined blocks 351. An inclined groove is formed on one side of the connecting inclined block 37. The inclined groove is arranged corresponding to the horizontal inclined block 351. The outer side of the roller 353 is attached to the inner wall of the inclined groove. When a centrifuge tube is added to drive the connecting inclined block 37 to press down, the inclined groove presses against the horizontal inclined block 351, driving the horizontal inclined block 351 to move to the other side, and jacking up the connecting inclined block 37 on the other side to balance the weight.

[0039] Magnets are arranged inside the connecting long plate 354. A rolling groove 352 is formed on the outer side of the horizontal inclined block 351. A rotating rod is fixedly connected to the inner wall of the rolling groove 352. A roller 353 is rotatably connected to the outer side of the rotating rod. By rolling the roller 353, the friction between the connecting inclined block 37 and the horizontal inclined block 351 is reduced. The magnets inside the connecting long plate 354 are used to reduce the friction between the connecting long plates 354.

[0040] The trimming component 38 includes a balancing box 381 fixedly connected to the bottom surface of the connecting inclined block 37. An inlet water groove 382 is formed on one side of the balancing box 381. A balancing groove 383 is also formed on one side of the balancing box 381. The balancing groove 383 is arranged above the inlet water groove 382. An inner baffle 391 is arranged on the inner wall of the liquid storage box 39. The inlet water groove 382 is attached to the inner wall of the inner baffle 391. When the centrifuge is in a balanced static state, the inlet water groove 382 is attached to the inner baffle 391, thereby preventing the coolant inside the liquid storage box 39 from entering the balancing box 381. When the balancing box 381 moves upward, the inlet water groove 382 is separated from the inner baffle 391 when the balancing box 381 moves upward, and the inlet water groove 382 leaks to start admitting coolant. The balancing groove 383 is used to balance the air pressure.

[0041] The separating ring assembly 34 includes an annular plate 341 rotatably connected inside the separating cylinder 31. A buffer pad B343 is fixedly connected to the inner wall of the annular plate 341. A side groove 342 is formed on one side of the annular plate 341. The buffer pad B343 is arranged corresponding to the side groove 342 and the placement groove A313. When placing the centrifuge tube, the placement groove A313 is separated from the placement groove B3131 by using the annular plate 341. The buffer pad B343 is used to buffer and protect the centrifuge tube during the centrifugation process. When the annular plate 341 rotates, the side groove 342 corresponds to the centrifuge tube, so that the centrifuge tube moves from the placement groove A313 to the placement groove B3131, facilitating subsequent centrifugation operations.

[0042] The auxiliary cover assembly 2 includes a cover ring 21 disposed above the arc-shaped ring plate 33. A connecting inclined plate 22 is fixedly connected to the inner wall of the cover ring 21. A magnet D 23 is fixedly connected to the bottom surface of the connecting inclined plate 22. A magnetic plate B 344 is fixedly connected to the upper surface of the annular plate 341. The magnet D 23 and the magnetic plate B 344 are magnetically attracted to each other. After placing the centrifuge tube, the cover ring 21 is placed above the arc-shaped ring plate 33 to prevent the centrifuge tube from slipping off. The magnet D 23 and the magnetic plate B 344 are aligned. By using the magnetic attraction between the magnet D 23 and the magnetic plate B 344, when the cover ring 21 rotates, it drives the annular plate 341 to rotate, thereby switching the correspondence between the buffer pad B 343, the side groove 342, and the centrifuge tube.

[0043] A plug rod 24 is fixedly connected to the bottom surface of the connecting inclined plate 22. A jack 355 is formed on the upper surface of the connecting long plate 354. The plug rod 24 and the jack 355 are correspondingly arranged. After the auxiliary cover assembly 2 is placed, the plug rod 24 is inserted into the jack 355 to limit the connecting long plate 354, ensuring the stability of the connecting long plate 354 during the centrifugation process.

[0044] A liquid discharging assembly 384 for discharging liquid is provided at the bottom of the balance box 381. The liquid discharging assembly 384 includes a sealing plate 3841 disposed on the bottom surface of the inner wall of the balance box 381. A connecting short block 3842 is fixedly connected to the bottom surface of the sealing plate 3841. The connecting short block 3842 penetrates through the bottom surface of the balance box 381. A magnetic plate A 3843 is fixedly connected to the bottom surface of the connecting short block 3842. A spring A 3844 is fixedly connected to the surface of the magnetic plate A 3843. The upper end of the spring A 3844 is fixedly connected to the bottom surface of the balance box 381. The liquid discharging component 4 includes a bottom box 41 fixedly connected to the bottom of the liquid storage box 39. The bottom box 41 is a hollow structure. An electromagnet 411 is fixedly connected to the inner wall of the bottom box 41. The electromagnet 411 and the magnetic plate A 3843 are correspondingly arranged. When it is necessary to discharge the coolant inside the balance box 381 after the centrifugation is completed, the electromagnet 411 is energized. By using the magnetic repulsion between the electromagnet 411 and the magnetic plate A 3843, the magnetic plate A 3843 is driven to move upward. The spring A 3844 is compressed, and at the same time, the connecting short block 3842 and the sealing plate 3841 move upward. The internal coolant flows out from the rising position of the sealing plate 3841 to complete the liquid discharging.

[0045] A drainage inclined pipe 42 is fixedly connected to one side of the bottom box 41, a vertical pipe 44 is fixedly connected to one side of the drainage inclined pipe 42, and a mounting chassis 43 is fixedly connected to the bottom surface of the vertical pipe 44. The bottom box 41, the drainage inclined pipe 42 and the vertical pipe 44 are internally connected, and a solenoid valve 46 is provided at the connection between the drainage inclined pipe 42 and the vertical pipe 44. An electric telescopic rod 45 is fixedly connected to the bottom surface of the mounting chassis 43. One end of the electric telescopic rod 45 passes through the mounting chassis 43 and is fixedly connected to a pressure plate 47. A one-way pressure valve A is provided inside the pressure plate 47. The upper end of the vertical pipe 44 is fixedly connected to the bottom surface of the liquid storage tray 5 and The interior is connected, and a one-way pressure valve B48 is provided at the connection between the vertical pipe 44 and the liquid storage pan 5. After the coolant is discharged from the balance box 381 and flows into the bottom box 41, it flows into the interior of the vertical pipe 44 through the drainage inclined pipe 42. Then the solenoid valve 46 is opened to close the connection between the drainage inclined pipe 42 and the vertical pipe 44. The electric telescopic rod 45 drives the pressure plate 47 to be pressed down. The coolant below flows to the surface of the pressure plate 47 through the one-way pressure valve A. The coolant moves upward by the upward movement of the pressure plate 47, so that the coolant squeezes the one-way pressure valve B48 and pours the coolant back into the liquid storage pan 5.

[0046] A magnetic plate C345 is fixedly connected to the outside of the annular plate 341, and the magnetic plate C345 is corresponding to the buffer pad B343. A push tube assembly 36 for pushing the centrifuge tube is provided on one side of the placement frame 311, and the push tube assembly 36 includes a side plate 361 fixedly connected to one side of the placement frame 311, and a spring B362 is fixedly connected to the inner wall of the side plate 361. A push plate 363 is fixedly connected to one side of the spring B362. The push plate 363 and the magnetic plate C345 magnetically repel each other. During the rotation of the annular plate 341, due to the magnetic repulsion between the magnetic plate C345 and the push plate 363, the push plate 363 is always compressed inside the side plate 361. After the annular plate 341 rotates and moves away, the push plate 363 pops out under the action of the spring B362, pushing the centrifuge tube into the placement groove B3131, ensuring that the centrifuge tube can stably enter the placement groove B3131.

[0047] Specifically, during detection, the centrifuge tube is first placed in the placement groove A313. Under the action of the gravity of the centrifuge tube, the soft pad pressing plate 314 is driven to press down, so that the spring rod 317 drives the connecting inclined block 37 to press down. During the downward movement of the connecting inclined block 37, the inner wall of the connecting inclined block 37 presses against the horizontal inclined block 351, driving the horizontal inclined block 351 to move to the other side, thereby driving the connecting inclined block 37 at the other end to move upward. The balance box 381 below the connecting inclined block 37 also moves upward at the same time. When the balance box 381 moves upward, the water inlet groove 382 is separated from the inner baffle 391. After the water inlet groove 382 is exposed, the coolant enters the balance box 381 from it. The balance groove 383 is used to balance the air pressure. By the entry of the coolant, the weight inside the balancing component 38 is increased to achieve automatic balancing. As the balancing progresses, the previously rising connecting inclined block 37 gradually descends until both sides are balanced. Subsequently, the insertion rod 24 is inserted into the insertion hole 355 to limit the connecting long plate 354, ensuring the stability of the connecting long plate 354 during the centrifugation process. The cover ring 21 is placed above the arc-shaped ring plate 33 to prevent the centrifuge tube from slipping off. The magnet D23 is aligned with the magnet plate B344. By the attraction between the magnet D23 and the magnet plate B344, when the cover ring 21 rotates, the annular plate 341 is driven to rotate, thereby switching the correspondence between the buffer pad B343, the side groove 342, and the centrifuge tube, allowing the centrifuge tube to enter the placement groove B3131 inside. Subsequently, the motor is started to complete the centrifugation operation. During the centrifugation process, the centrifuge tube is tilted and pressed downward under the action of centrifugal force, driving the soft pad pressing plate 314 to press down further, and then squeezing the air inside the air storage tank 315, so that the airbag inflates, using the buffer pad A312 to fit the centrifuge tube more stably to ensure the clamping effect. When the coolant inside the balance box 381 needs to be discharged after the centrifugation operation, the electromagnet 411 is energized. Using the magnetic repulsion between the electromagnet 411 and the magnet plate A3843, the magnet plate A3843 is driven to move upward. While the spring A3844 is compressed, the connecting short block 3842 and the sealing plate 3841 also move upward, and the internal coolant flows out from the rising part of the sealing plate 3841. After the coolant flows out of the balance box 381 and into the bottom box 41, it flows into the vertical tube 44 through the liquid discharge inclined tube 42. Subsequently, the solenoid valve 46 is opened to close the connection between the liquid discharge inclined tube 42 and the vertical tube 44. The liquid pressing plate 47 is driven to press down by the electric telescopic rod 45. The coolant below surges towards the surface of the liquid pressing plate 47 through the one-way pressure valve A. The coolant is driven to move upward by the upward movement of the liquid pressing plate 47, so that the coolant squeezes open the one-way pressure valve B48, and the coolant is poured back into the liquid storage tray 5 for reuse. Finally, the purpose of automatic balancing when the centrifuge tube is placed and enhancing the fixing effect is achieved.
