Description

Technical Field

[0001] The utility model relates to the field of medical diagnostic instruments, and particularly relates to a sample analyzer and a reaction cup conveying structure. Background Art

[0002] A sample analyzer is a widely used inspection instrument in the field of in vitro diagnosis technology. It can obtain clinical diagnostic information by detecting samples such as human blood and body fluids, and provide a basis for the diagnosis of diseases and the judgment of body functions.

[0003] When a sample analyzer works, a large number of reaction containers are required for the reagent and the sample to undergo a biochemical reaction by mixing. There are various reaction containers, such as reaction cups with one end closed and the other end open. Existing sample analyzers generally use a reaction cup conveying device to convey a large number of messy reaction cups in a linear direction with the same orientation in an array. When conveying, the reaction cups are hung in a chute and slide down through the flange on the outer side of the reaction cup. Therefore, before the reaction cup enters the chute, it is necessary to ensure that the bottom of the reaction cup faces one side of the chute, so that the bottom of the reaction cup enters the chute first, so as to ensure that the reaction cup can maintain an overall hanging state in the chute. However, before the existing reaction cup conveying device conveys the reaction cup into the chute, some reaction cups will have the situation that the bottom is far from one side of the chute, resulting in the reaction cup sliding into the chute from the cup mouth side. As Figure 1 shown, since the flange on the outer side of the reaction cup used in the sample analyzer is located at the cup mouth, the distance between the cup mouth of the reaction cup that has been arranged and cached in the chute and the surface of the chute is too short. When the subsequent reaction cup slides down along the chute, due to the action of inertia, it is easy to rush out of the chute along the surface of the neatly arranged reaction cups, resulting in the phenomenon of cup flushing. Summary of the Invention

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] As shown in Figure 2 、 Figure 3 , a reaction cup conveying structure includes: a hopper 1 for storing reaction cups 2 disorderly; a cup - separating tray 3 for storing and transferring reaction cups 2; a cup feeding device 4 and a chute 5. One end of the cup feeding device 4 is connected to the hopper 1, and the other end is connected to the chute 5 for conveying the reaction cups 2 in the hopper 1 to the chute 5. The chute 5 receives the reaction cups 2 conveyed by the cup feeding device 4 and enables them to enter the cup - separating tray 3 in a linear arrangement; a cup - deflecting piece 6 is installed on one side of the cup feeding device 4 for deflecting the reaction cups 5 with the cup mouths facing the chute 5 side on the cup feeding device 4 into the hopper 1.

[0032] With the provision of the cup deflecting piece, the present utility model can deflect the reaction cups with the cup mouths facing the chute side on the cup feeding device into the hopper, so that all the reaction cups transported by the cup feeding device to the chute are with the bottoms facing the chute side. The bottoms of the reaction cups enter the chute first, ensuring that all the reaction cups can be in a suspended state in the chute, and avoiding the occurrence of the cup flushing phenomenon caused by the cup mouth side of the reaction cup entering the chute first.

[0033] It can be understood that, in order to prevent damage or blockage to the cup feeding device 4 when the cup deflecting piece 6 deflects the reaction cup 2, the cup deflecting piece 6 of the present utility model is made of an elastic material.

[0034] Furthermore, one end of the cup deflecting piece 6 is fixed on the hopper 1, and the other end extends into the cup feeding device 4 for deflecting the reaction cups 2 on the cup feeding device 4.

[0035] As Figure 4 shown, an embodiment of the reaction cup 2 used in the present utility model includes a cup body 7 and a flange 8 provided on the outer side of the cup body 7; when the reaction cup 2 enters the cup feeding device 4 with the cup mouth facing the chute 5 side and the cup feeding device 4 carries the reaction cup 2 to move upward, the cup deflecting piece 6 extending into the cup feeding device 4 will block the flange 8 of the cup mouth of the reaction cup 2, causing the reaction cup 2 to turn over and fall into the hopper 1 on the cup feeding device 4; when the reaction cup 2 enters the cup feeding device 4 with the cup bottom facing the chute 5 side, since there is no flange on the outer side of the bottom of the cup body 7, the cup deflecting piece 6 extending into the cup feeding device 4 will not block the cup bottom 7, so it can smoothly pass through the cup deflecting piece 6 and move to the chute 5 for normal sliding.

[0036] As Figure 5 shown, the cup feeding device 4 includes a driving mechanism and a plurality of cup-hooking sliders 9; the driving mechanism is used to drive the plurality of cup-hooking sliders 9 to move from the hopper 1 to the chute 5 side. The plurality of cup-hooking sliders 9 pick up the reaction cups 2 from the hopper 1, and the driving mechanism carries the cup-hooking sliders 9 loaded with the reaction cups 2 to move to align with the chute 5, and then the reaction cups 2 slide from the cup-hooking sliders 9 to the chute 5.

[0037] As Figure 6 shown, the cup-hooking slider 9 includes a fixed block 10 and a protrusion 11 provided on the fixed block 10; the protrusion 11 inclines towards the chute 5 side and can be aligned with the chute 5 for receiving the reaction cups 2 in the hopper 1. At the same time, in order to smoothly deflect the reaction cups 2 with the cup mouths facing the chute 5 side on the protrusion 11 into the hopper 1, the end of the cup deflecting piece 6 extending into the cup feeding device 4 is close to the lower side of the protrusion 11.

[0038] As Figure 2 、 Figure 5As shown in the figure, the driving mechanism includes a transmission chain 12, a driving sprocket 13, a driven sprocket 14, a transmission gear 15, an intermediate gear 16 and a driving motor 17; the transmission chain 12 is arranged between the driving sprocket 13 and the driven sprocket 14; the driving sprocket 13 is fixed on the transmission gear 15; the transmission gear 15 meshes with the driving motor 17 through the intermediate gear 16.

[0039] A plurality of hook cup sliders 9 are arranged on the surface of the transmission chain 12. The driving motor 17 drives the intermediate gear 16 to rotate, and the intermediate gear 16 drives the transmission gear 15 to rotate to drive the driving sprocket 13 to rotate. The transmission chain 12 provided with a plurality of hook cup sliders 9 is driven by the driving sprocket 13 to rotate between the driving sprocket 13 and the driven sprocket 14.

[0040] Furthermore, an origin sensor 18 is also arranged on the output shaft of the driving motor 17, which is used to control the driving motor 17 to rotate the same angle each time, so as to ensure that the hook cup sliders 9 on the surface of the transmission chain 12 stop after moving the same distance each time, so as to ensure that there is always a hook cup slider 9 aligned with one end of the chute 5, reducing the failure probability that the hook cup slider 9 and the chute 5 cannot be aligned, and enabling the reaction cup 2 in the hook cup slider 9 to slide smoothly into the chute 5.

[0041] As Figure 7 shown, in order to improve the intelligent control degree of the present utility model, the present utility model further includes a controller. At the same time, a first sensor 19, a second sensor 20 and a third sensor 21 are arranged at one end of the chute 5 close to the cup dividing disc 3; the first sensor 19, the second sensor 20 and the third sensor 21 are arranged successively upward along the bottom of the chute 5.

[0042] After the reaction cup 2 of the present utility model slides into the chute 5, due to its large top size and small bottom size, it forms a state of being arranged in sequence with the opening facing upward. When the second sensor 20 or / and the third sensor 21 detects the reaction cup, it indicates that there are enough reaction cups 2 arranged at the bottom of the chute 5. Therefore, the controller controls the driving motor 17 not to drive the transmission chain 12 to perform the cup feeding operation; when the second sensor 20 does not detect the reaction cup, the controller controls the driving motor 17 to continuously drive the transmission chain 12 to perform the cup feeding operation; when none of the first sensor 19, the second sensor 20 and the third sensor 21 detects the reaction cup 2, the controller controls the driving motor 17 to continue to operate a certain number of times and then stop operating and feedback the error information to the controller. At the same time, the cup dividing disc 3 is controlled to stop operating and wait until the first sensor 19 at the bottom of the chute 5 detects the reaction cup 2 and then continue to operate.

[0043] Furthermore, a pushing mechanism 22 is further included, which is used to push the reaction cup 2 in the hopper 1 into the hook cup slider 9.

[0044] Furthermore, a residual sensor 23 is provided in the hopper 1; the residual sensor 23 of the utility model is a beam sensor, and the accumulation state of the reaction cups 2 gradually decreasing in the hopper 1 is uncertain, and the use of other sensors may result in unstable detection.

[0045] Furthermore, a fan 24 is provided at one end of the cup feeding device 4 located at the slide 5; when some reaction cups 2 move to the slide 5 along with the cup feeding device 4, due to the friction between the reaction cups 2 and the hook cup slider 9, the reaction cups 2 cannot slide smoothly from the hook cup slider 9 into the slide 5. At this time, turning on the fan 24 can help the reaction cups 2 slide smoothly into the slide 5.

[0046] Working principle: when a large number of reaction cups 2 are poured into the hopper 1, the reaction cups 2 are in a disordered state. At this time, the driving motor 17 drives the transmission gear 15 to rotate, driving the conveying chain 12 to move obliquely upward. The hook cup slider 9 is assembled on the conveying chain 12. When passing through the disordered reaction cups 2 inside the hopper 1, the pushing mechanism 22 moves up and down along the moving direction of the conveying chain 12 to push the reaction cups 2 onto the hook cup slider 9; at the same time, due to the large number of disordered reaction cups 2 inside the hopper 1, some reaction cups 2 automatically slide into the hook cup slider 9. When the conveying chain 12 rises to one side of the chute 5 with the hook cup slider 9, the reaction cups 2 will automatically slide into the chute 5 due to their own weight, but some reaction cups 2 will not be able to slide due to the friction resistance with the hook cup slider 9. At this time, the fan 24 is turned on to help the reaction cups 2 slide accurately into the chute 5; the reaction cups 2 slide to After the chute 5, due to the large size at the top and the small size at the bottom, the openings are arranged in sequence upward. When the second sensor 20 or / and the third sensor 21 detect the reaction cup, it indicates that there are enough reaction cups 2 arranged at the bottom of the chute 5, so the controller controls the driving motor 17 to no longer drive the conveying chain 12 to perform the cup feeding operation; when the second sensor 20 does not detect the reaction cup, the controller controls the driving motor 17 to continue to drive the conveying chain 12 to perform the cup feeding operation; when the first sensor 19, the second sensor 20 and the third sensor 21 do not detect the reaction cup 2, the controller controls the driving motor 17 to continue to operate for a certain number of times. If the above sensors still do not detect the reaction cup, the controller stops the operation and feeds back the error information to the controller. At the same time, the cup-distributing plate 3 is controlled to stop operating and wait for the first sensor 19 at the bottom of the chute 5 to detect the reaction cup 2 before continuing to operate.

[0047] The utility model also discloses a sample analyzer, which comprises the reaction cup conveying structure described above.

[0048] The utility model can gradually arrange the reaction cups stacked disorderly in the hopper in an orderly manner during the transportation process, and through the arrangement of the cup-pushing piece, the occurrence of cup collision when the reaction cup slides in the chute is effectively avoided, thereby improving the detection efficiency of the instrument.

[0049] The above are only the embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model are included within the scope of the claims of the present utility model pending approval of the application.
