Description

Technical Field

[0001] The invention belongs to the field of medical technology, and more specifically, particularly relates to a quantitative filling device for testing reagents used in a hospital laboratory. Background Art

[0002] When testing a test product in a hospital laboratory, it is necessary to place the test reagent in a reagent bottle first. At this time, a filling device is needed, but the existing filling device has the following disadvantages:

[0003] 1. When the existing filling device is in use, the reagent will be discharged through the discharge pipe of the device. However, when discharging the reagent, the existing filling device cannot scrape and discharge the reagent on the wall of the discharge pipe, resulting in the reagent sticking to the wall of the pipe after discharging, causing the actual discharge amount to be less than the expected discharge amount, resulting in errors in the test data.

[0004] 2. After the existing discharge pipe is discharged, a large amount of reagents will remain in the pipe wall. The residual reagents will undergo qualitative changes after coming into contact with the air. During the next discharge, the residual reagents from the last time may fall, causing an erroneous chemical reaction during hospital testing, resulting in test errors.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, the first float and the second float are affected by buoyancy to move upward and reset into the feed port, and at the same time, the air in the storage tube is discharged through the exhaust pipe. When the plug is reset, the feed tube stops feeding. At this time, the user places the reagent bottle in the rubber sleeve and manually rotates the connecting rod to magnetically attract the fourth magnetic block and the third magnetic block. At this time, the second motor drives the push plate to move downward, and the push plate moves downward to completely scrape the reagent inside the storage tube and drop it. By designing the filling machine into two-stage adjustment, on the one hand, the amount of reagent received in each test can be adjusted, and on the other hand, it can ensure that the reagent inside the storage tube can fall completely each time, thereby reducing residue and improving the accuracy of the reagent test.

[0014] In the present invention, before the user places the reagent bottle inside the rubber sleeve, the user can adjust the height of the support seat according to reagent bottles of different lengths. The user rotates the support seat, and the support seat rotates above the support column through the thread, and the height is raised and lowered at the same time. Then the user places the reagent bottle into the rubber sleeve. The rubber sleeve has a certain elasticity and thickness, so the reagent bottle can be clamped firmly, which can facilitate the use of reagent bottles of different models and improve the stability of the reagent bottle in receiving reagents.

[0015] In the present invention, the movement of the curved frame will drive the upper disc to move, the movement of the upper disc will drive the movement of the second motor, and the movement of the second motor will drive the lower push plate to move through the second threaded rod, so that the heights of the upper disc and the lower push plate inside the storage tube will change, and the height of the lower push plate determines the amount of material discharged from the storage tube at a single time. By adjusting the height of the lower push plate to adjust the single material discharge amount, the material discharge amount can be kept accurate each time, and the adjustment is more accurate and intuitive. In the existing device, the storage tube is longer and the discharge amount is lower, resulting in a large area of ​​the reagent material sticking to the tube wall of the storage tube, resulting in the discharge amount failing to meet the test standard.

[0016] In the present invention, the second motor is operated to drive the second threaded rod to rotate through the output shaft, and the second threaded rod cooperates with the upper disc through the thread. Since the upper disc cannot rotate, the lower push plate is horizontally fixed by the main pipe frame, so the second threaded rod will move downward, and the downward movement of the second threaded rod will drive the lower push plate to move downward. The downward movement of the lower push plate will push the reagent in the storage tube downward, and at the same time, it will push the reagent stuck to the wall of the storage tube to fall, effectively avoiding the situation where the reagent sticks to the wall of the storage tube after discharging, resulting in the actual discharge amount being less than the expected discharge amount, resulting in errors in the test data. The present device effectively improves the accuracy of discharging.

[0017] In the present invention, after the existing storage tube is unloaded, a large amount of reagents will remain in the tube wall. The residual reagents will undergo a qualitative change after coming into contact with the air. When the material is unloaded next time, the residual reagents from the previous time may fall down, causing an erroneous chemical reaction during hospital testing, resulting in test errors. The present device effectively reduces the error probability of such detection by pushing out the reagents remaining on the inner wall of the storage tube.

[0018] In the present invention, when the reagent is almost full and contacts the first float and the second float, the first float and the second float are driven by the buoyancy to move the plug upward, and at the same time, the air inside the storage tube is discharged through the main pipe rack, and the second float can control the plug to move upward as a whole, and the first float can assist the plug to rotate forward and reset, thereby ensuring that the plug can be accurately reset. At the same time, the upper plug block above the first magnetic block and the magnetic suction of the feed port can help the plug to quickly reset, thereby accurately cutting off the feed of the feed tube, greatly improving the speed and accuracy of automatic feeding of the equipment, and further improving the accuracy of detection.

[0019] In the present invention, the rubber plug is inserted into the storage tube by the connecting rod, and the fifth magnetic block and the lower end of the storage tube are magnetically attracted at the same time. By designing the lower cover plate to be manually adjusted, the reagent inside the storage tube can slowly fall, and the storage tube is effectively prevented from being far away from the reagent bottle, resulting in splashing of the reagent inside the storage tube when it falls, causing pollution and damage. The device greatly improves the stability of the reagent when it falls, and ensures the hygiene level of the material taking process. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A support column 11 is fixedly installed at the bottom of the discharge bin 49, a support seat 12 is installed on the upper end of the support column 11 through a thread, a rubber sleeve 13 is fixedly installed on the upper end of the support seat 12, and the rubber sleeve 13 is used to fix the reagent bottle, a first threaded rod 15 is fixedly installed on the end of the output shaft of the first motor 14, a fixing sleeve 16 is fixedly installed on the inner wall of the filler 1, and the top of the first threaded rod 15 is rotatably connected to the fixing sleeve 16, the user rotates the support seat 12, and the support seat 12 rotates above the support column 11 through a thread, and the height is raised and lowered at the same time, and the filling machine 10 is filled with a plurality of pieces of material. The user then places the reagent bottle into the rubber sleeve 13. The rubber sleeve 13 has a certain elasticity and thickness, so it can hold the reagent bottle firmly, which is convenient for the use of reagent bottles of different types and can improve the stability of the reagent bottle in receiving reagents. The lower end of the curved frame 17 located on the outside of the storage tube 4 is arranged on the outside of the first threaded rod 15 through a threaded sleeve and cooperates with the first threaded rod 15. The fitting surface of the curved frame 17 and the storage tube 4 is provided with an arc groove 18, and the side wall of the curved frame 17 located inside the storage tube 4 is penetrated by a side slide rail 19.

[0033] A second motor 24 is installed on the side of the curved frame 17, and a side slide 25 is fixedly installed on the side end of the second motor 24, and the side slide 25 is slidably installed in the side slide rail 19 opened in the curved frame 17.

A rib 28 is fixedly installed on the lower end of the lower push plate 27, and the rib 28 is conical and close to the edge of the lower push plate 27. Since the outer wall of the curved frame 17 cooperates with the first threaded rod 15 through a thread, the rotation of the first threaded rod 15 will drive the curved frame 17 to rotate. The frame 17 moves upward or downward, and the movement of the curved frame 17 will drive the upper disc 2 to move. The movement of the upper disc 2 will drive the second motor 24 to move. The movement of the second motor 24 will drive the lower push plate 27 to move through the second threaded rod 26, so that the heights of the upper disc 2 and the lower push plate 27 inside the storage tube 4 will change. The height of the lower push plate 27 determines the amount of material discharged from the storage tube 4 at a single time. A discharge port 29 is penetrated and opened at the lower end of the lower push plate 27. The second magnetic block 39 is located at the outer circle of the discharge port 29. Two support frames 38 are located on the left and right sides of the second magnetic block 39. An upper plug block 36 is fixedly installed at the upper end of the plug 3. The upper plug block 36 is inserted into the inside of the discharge port 29, and a first magnetic block 35 is installed at the upper end of the plug 3.

[0034] A spring 37 is fixedly installed on the upper end of the front side of the plugging plug 3, and the upper end of the spring 37 is fixedly connected to the bottom of the lower push plate 27, and a second float 32 and a first float 31 are fixedly installed on the lower end of the plugging plug 3, and the second float 32 is located in the middle of the plugging plug 3, and the first float 31 is located at the rear side of the second float 32. A conical tube 48 is fixedly installed inside the storage tube 4 near the lower end opening, and the plugging plug 3 is pushed downward as a whole, and the plugging plug 3 drives the two sliders 34 to slide downward, and the two sliders 34 slide in the two support frames 38. When the upper plug block 36 slides away from the discharge port 29, the plugging plug 3 will rotate. Since a spring 37 is installed between the front side of the plugging plug 3 and the lower push plate 27, the rear side of the plugging plug 3 will rotate. At this time, the reagent falls into the storage tube 4, and the third magnetic block 41 and the rotating shaft frame 42 are fixedly installed on the left outer wall of the storage tube 4. The rotating shaft frame 42 is located below the third magnetic block 41. A lower cover plate 43 is installed below the storage tube 4, and a rubber plug 47 is fixedly installed on the upper end of the lower cover plate 43, and the rubber plug 47 is located inside the storage tube 4, and a fifth magnetic block 46 is fixedly installed on the upper end of the lower cover plate 43, and the fifth magnetic block 46 is located on the outer circle of the rubber plug 47, and a connecting rod 44 is fixedly installed on the lower end of the lower cover plate 43. The connecting rod 44 is rotatably sleeved outside the rotating shaft frame 42, and a torsion spring is arranged between the connecting rod 44 and the rotating shaft frame 42, the cross-section of the connecting rod 44 is Z-shaped, and a fourth magnetic block 45 is fixedly installed on the upper surface of the connecting rod 44.

[0035] Working principle:

[0036] In the first step, a storage bin is installed on the top of the filling machine 1, and the storage bin is connected to the feeding pipe 23. Before taking materials for the test, the user can start the first motor 14 to drive the curved frame 17 to move up and down, and the curved frame 17 drives the upper disc 2 and the lower push plate 27 to move up and down, so as to adjust the amount of reagent received by the storage tube 4. When the user needs to take the reagent from the reagent bottle, the pump body inside the storage bin transports the reagent downward through the feeding pipe 23, and the reagent moves downward to push the plug 3 downward, and the plug 3 drives the upper plug block 36 to leave the discharge port 29. At this time, the reagent enters the storage tube 4. As the reagent inside the storage tube 4 gradually rises, the reagent contacts the first float 31 and the second float 32. The first float 31 and the second float 32 are moved upward and downward. The second float 32 moves upward under the influence of buoyancy and resets into the discharge port 29. At the same time, the air in the storage tube 4 is discharged through the exhaust pipe 22. When the plug 3 is reset, the feeding tube 23 stops discharging. At this time, the user places the reagent bottle in the rubber sleeve 13, and manually rotates the connecting rod 44 so that the fourth magnetic block 45 and the third magnetic block 41 are magnetically attracted. At this time, the second motor 24 drives the push plate 27 to move downward. The push plate 27 moves downward to completely scrape and drop the reagent inside the storage tube 4. By designing the filling machine 1 into two-stage adjustment, on the one hand, the amount of reagent received in each test can be adjusted, and on the other hand, it can ensure that the reagent inside the storage tube 4 can fall completely each time, thereby reducing residue and improving the accuracy of the reagent test.

[0037] In the second step, before the user places the reagent bottle inside the rubber sleeve 13, the user can adjust the height of the support seat 12 according to the reagent bottles of different lengths. The user rotates the support seat 12, and the support seat 12 rotates above the support column 11 through the thread, and the height is raised and lowered at the same time. Then the user places the reagent bottle into the rubber sleeve 13. The rubber sleeve 13 has a certain elasticity and thickness, so the reagent bottle can be clamped stably, which can facilitate the use of reagent bottles of different models and improve the stability of the reagent bottle in receiving the reagent;

[0038] Before the experiment, the user can adjust the amount required for the next reagent bottle, start the first motor 14, and the first motor 14 drives the first threaded rod 15 to rotate through the output shaft. Since the outer wall of the curved frame 17 cooperates with the first threaded rod 15 through the thread, the rotation of the first threaded rod 15 will drive the curved frame 17 to move upward or downward, and the movement of the curved frame 17 will drive the upper disc 2 to move, and the movement of the upper disc 2 will drive the second motor 24 to move, and the movement of the second motor 24 will drive the lower push plate 27 to move through the second threaded rod 26, so that the height of the upper disc 2 and the lower push plate 27 inside the storage tube 4 will change, and the height of the lower push plate 27 determines the amount of material discharged from the storage tube 4 at a time. By adjusting the height of the lower push plate 27 to adjust the word discharge amount, the discharge amount can be kept accurate each time, and the adjustment is more accurate and intuitive. In the existing device, the storage tube 4 is longer and the discharge amount is lower, resulting in a large area of ​​the reagent material sticking to the tube wall of the storage tube 4, resulting in the discharge amount failing to reach the test standard;

[0039] When receiving the material, the lower cover plate 43 is opened, and then the second motor 24 operates to drive the second threaded rod 26 to rotate through the output shaft. The second threaded rod 26 cooperates with the upper disc 2 through the thread. Since the upper disc 2 cannot rotate, the lower push plate 27 is horizontally fixed by the main pipe frame 21, so the second threaded rod 26 will move downward, and the downward movement of the second threaded rod 26 will drive the lower push plate 27 to move downward. The downward movement of the lower push plate 27 will push the reagent in the storage tube 4 downward, and at the same time, it will push the reagent stuck to the wall of the storage tube 4 to fall, effectively avoiding the situation that the reagent sticks to the wall of the storage tube 4 after discharging, resulting in the actual discharge amount being less than the expected discharge amount, resulting in errors in the test data. The device effectively improves the accuracy of discharging;

[0040] After the existing storage tube 4 is unloaded, a large amount of reagents will remain in the tube wall. The residual reagents will undergo qualitative changes after contact with the air. When the material is unloaded next time, the residual reagents from the last time may fall, resulting in an erroneous chemical reaction during the hospital test, resulting in test errors. The device effectively reduces the error probability of such detection by pushing out the residual reagents on the inner wall of the storage tube 4;

[0041] When the feed pipe 23 is unloaded, the reagent falls downward through the feed pipe 23 and pushes the plug 3 downward as a whole. The plug 3 drives the two sliders 34 to slide downward. The two sliders 34 slide in the two support frames 38. When the upper plug block 36 slides away from the unloading port 29, the plug 3 rotates. Since a spring 37 is installed between the front side of the plug 3 and the lower push plate 27, the rear side of the plug 3 rotates. At this time, the reagent falls into the storage tube 4. When the reagent is almost full and contacts the first float 31 and the second float 32, the first float 31 and the second float 32 are The float 32 is driven by the buoyancy to move the plug 3 upward, and at the same time, the air inside the storage pipe 4 is discharged through the main pipe rack 21. The second float 32 can control the plug 3 to move upward as a whole, and the first float 31 can assist the plug 3 to rotate forward and reset, thereby ensuring that the plug 3 can be accurately reset. At the same time, the upper plug block 36 above the first magnetic block 35 and the discharge port 29 are magnetically attracted to help the plug 3 to quickly reset, thereby accurately cutting off the discharge of the feed pipe 23, greatly improving the speed and accuracy of automatic discharge of the equipment, and further improving the accuracy of detection.

[0042] The third step is that when the experimenter takes the material, the user uses his hand to quickly rotate the connecting rod 44 to the left, and the connecting rod 44 is forced to drive the lower cover plate 43 to rotate. The rotation of the connecting rod 44 drives the torsion spring on the rotating shaft frame 42 to be forced, and at the same time, the fourth magnetic block 45 is magnetically attracted to the third magnetic block 41, and at the same time, the fifth magnetic block 46 is magnetically separated from the lower end of the storage tube 4. At this time, the reagent inside the storage tube 4 can fall smoothly. After the material is connected, the user rotates the connecting rod 44 to the right, and the connecting rod 44 drives the rubber plug 47 to be inserted into the storage tube 4, and at the same time drives the fifth magnetic block 46 and the lower end of the storage tube 4 to be magnetically attracted. By designing the lower cover plate 43 to be manually adjusted, the reagent inside the storage tube 4 can fall slowly, effectively avoiding the storage tube 4 being far away from the reagent bottle, resulting in splashing of the reagent inside the storage tube 4 when it falls, causing pollution and damage. The device greatly improves the stability of the reagent when it falls, and ensures the hygiene level of the material taking link;

[0043] The conical tube 48 is installed near the discharge port of the storage tube 4 to reduce the speed of the feed tube 23 when discharging materials, reduce the impact force between reagents, and effectively reduce the impact force of the reagents on the lower cover plate 43, thereby ensuring the stability of the inside of the storage tube 4.

Many modifications and variations will be apparent to those of ordinary skill in the art.
