Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a trash can module and a nucleic acid testing device. Background Technology

[0002] Used disposable tip heads, reaction cups, and other medical waste from in vitro diagnostic equipment are ultimately disposed of in the waste bins inside the equipment. Because the disposal location and the opening of the waste bin are fixed, there is a problem where the area near the opening of the waste bin is filled with medical waste, while other parts of the waste bin are not filled with medical waste.

[0003] A waste bin assembly exists, in which the waste bin is installed within a bracket cavity. A drive mechanism propels the bracket to move linearly along a guide rail, adjusting the position of the waste bin to facilitate the placement of medical waste at different locations within the bin, preventing waste accumulation and low space utilization. However, this design has an assembly gap between the waste bin and the bracket. If the reciprocating speed is too high, additional abnormal noise may occur. Alternatively, when the sample analyzer is running, the waste bin assembly is susceptible to shaking and noise due to the mixing and processing of nearby sample pretreatment modules. Furthermore, removing or placing the waste bin requires pulling it out or inserting it from above, which, from an ergonomic perspective, poses a risk of waste spillage due to instability. Utility Model Content

[0004] The primary objective of this invention is to provide a trash can module that can prevent trash cans from shaking and reduce noise.

[0005] The second objective of this invention is to provide a nucleic acid testing setup that includes the aforementioned trash can module.

[0006] To achieve the aforementioned first objective, the present invention provides a trash can module comprising a mounting plate, a bracket, a trash can, and a drive assembly. The bracket is slidably mounted on the mounting plate, and the trash can is detachably mounted on the bracket. The drive assembly drives the bracket and the trash can to move linearly back and forth. The bracket is provided with a guide groove and a first magnetic attractor. One end of the guide groove has an inlet and outlet, and the first magnetic attractor is located at the end of the guide groove away from the inlet and outlet. The trash can is located in the guide groove, and one end of the trash can is provided with a second magnetic attractor. The second magnetic attractor is flexibly connected to the trash can, and the second magnetic attractor is correspondingly arranged with the first magnetic attractor and can be magnetically connected.

[0007] As can be seen from the above scheme, by setting the first magnetic suction component and the second magnetic suction component to be magnetically connected, it is convenient to fix the trash can on the bracket and prevent the trash can from moving relative to the bracket during linear reciprocating movement. On the one hand, this helps to ensure that the trash can is always on the bracket and avoids being thrown out. On the other hand, it helps to avoid noise caused by the movement of the trash can relative to the bracket. By setting the second magnetic suction component to be flexibly connected to the trash can, it is not only conducive to the two magnetic suction components adapting to the ground surface, but also has a buffering effect.

[0008] A further option is that one of the first and second magnetic components is an electromagnet, and the other is a permanent magnet, a magnetic metal plate, and / or a magnetic assembly.

[0009] As can be seen from the above scheme, the above settings facilitate the control of the attraction and separation of the first magnetic suction component and the second magnetic suction component; when it is necessary to remove the trash can, the magnetic connection between the first magnetic suction component and the second magnetic suction component can be cut off first, and then the trash can can move in the guide groove, making it easy and effortless for staff to remove the trash can.

[0010] A further solution is to install an elastic element between the second magnetic component and the trash can, with the extension and retraction direction of the elastic element parallel to the movement direction of the trash can.

[0011] A further option is that the trash can module also includes a positioning detection component, which includes a positioning detector and a sensor. The positioning detector is mounted on the bracket, and the sensor is mounted on the trash can and moves with the trash can. The positioning detector and the sensor are configured accordingly.

[0012] As can be seen from the above scheme, the above settings make it easy to detect whether the trash can has moved into place. Once the trash can has moved into place, the electromagnet can be energized immediately to fix the trash can in place by magnetic attraction. After that, the bracket can drive the trash can to perform linear reciprocating motion.

[0013] A further solution is to install guide strips on both sides of the bracket, forming a guide groove between the two guide strips, and place the trash can in the guide groove.

[0014] As can be seen from the above scheme, the above settings make it easy to restrict the position of the trash can in the horizontal direction of the bracket.

[0015] A further solution is to install a limit block at the end of the guide channel away from the entrance / exit, and the limit block can abut against the trash can.

[0016] As can be seen from the above scheme, the above settings can effectively limit the position of the trash can in the longitudinal direction of the bracket, and prevent damage to the magnetic components.

[0017] A further option is that the trash can module also includes a motion detection component, which includes a trigger and two detection sensors. The two detection sensors are arranged on the mounting plate along the movement direction of the bracket, and the trigger is set on the bracket and moves back and forth between the two detection sensors.

[0018] As can be seen from the above scheme, the above settings facilitate the detection and recording of the number of reciprocating movements of the bracket and its current position.

[0019] A further option is to include a drive assembly comprising a motor and an eccentric linkage mechanism, wherein the motor drives the bracket to reciprocate linearly via the eccentric linkage mechanism.

[0020] As can be seen from the above scheme, the above settings facilitate the linear reciprocating motion of the bracket and the trash can.

[0021] To achieve the second objective mentioned above, this utility model provides a nucleic acid testing device, which includes the aforementioned trash can module.

[0022] A further proposed solution is that the nucleic acid testing equipment also includes a reagent module, a sample module, a pipette tip module, an incubation and interpretation module, a transport module, an auxiliary reagent module, and a sample pretreatment module. The sample pretreatment module and the sample module are both located on the first side of the transport module, the incubation and interpretation module and the pipette tip module are both located on the second side of the transport module, the auxiliary reagent module is located between the incubation and interpretation module and the pipette tip module, the reagent module is located at the end of the transport module, and the waste bin module is located below the sample module, with the waste inlet of the waste bin module located close to the transport module.

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0038] Example of a trash can module:

[0039] See Figures 1 to 3 The trash can module 10 provided in this embodiment includes a mounting plate 1, a bracket 2, a trash can 3, and a drive assembly 4.

[0040] The bracket 2 is slidably mounted on the mounting plate 1, and the drive assembly 4 is fixedly mounted on the mounting plate 1 and located at one end of the longitudinal direction of the bracket 2. The trash can 3 is detachably mounted on the bracket 2. The drive assembly 4 drives the bracket 2 and the trash can 3 to reciprocate longitudinally, so that the waste reaction tube, waste suction head and other waste near the inlet of the trash can 3 can be spread out to other positions inside the trash can 3 during its reciprocating movement, avoiding the accumulation of waste.

[0041] The bracket 2 is equipped with a fixing seat 24, a first magnetic suction element 25, and two guide strips 21. The two guide strips 21 are respectively located on both sides of the bracket 2 laterally, forming a longitudinally extending guide groove 22 between them. One end of the guide groove 22 has an inlet / outlet. The trash can 3 is movably positioned within the guide groove 22, with the end of the trash can 3 equipped with a handle 32 located near the inlet / outlet, allowing staff to easily, comfortably, and effortlessly remove and move the trash can 3 from the inlet / outlet without risking spillage during removal. The fixing seat 24 is located at the end of the guide groove 22 furthest from the inlet / outlet. The first magnetic suction element 25 is mounted on the fixing seat 24.

[0042] The two ends of the trash can 3 are respectively provided with a second magnetic suction member 31 and a handle 32. The second magnetic suction member 31 is correspondingly provided with the first magnetic suction member 25 and can be magnetically connected, which serves to fix the trash can 3 on the bracket 2, ensuring that the trash can 3 will not detach from the inlet and outlet of the guide groove 22 during the reciprocating movement of the bracket 2.

[0043] One of the first magnetic attractor 25 and the second magnetic attractor 31 is an electromagnet, and the other is a permanent magnet, a magnetic metal plate, and / or a magnetic assembly. The magnetic assembly includes a thin plate and a magnet, with the magnet positioned between the thin plate and the end wall of the trash can 3. In this embodiment, the first magnetic attractor 25 is preferably an electromagnet, and the second magnetic attractor 31 is a magnetic metal plate. When the electromagnet is energized, it can magnetically connect with the magnetic metal plate. The magnetic metal plate has a protrusion on the side near the trash can 3, and the end wall of the trash can 3 has a receiving groove (not shown in the figure). The depth of the receiving groove is greater than the height of the protrusion, and the protrusion is embedded in the receiving groove to position the magnetic metal plate, facilitating assembly.

[0044] The second magnetic suction member 31 is flexibly connected to the trash can 3. Specifically, multiple elastic members 5 and multiple locking members 6 are provided between the second magnetic suction member 31 and the trash can 3. The extension and retraction direction of each elastic member 5 is parallel to the movement direction of the trash can 3, and the locking members 6 are inserted into the end wall of the trash can 3 through the second magnetic suction member 31 and the elastic members 5 in sequence. The locking members 6 are preferably screws, and the elastic members 5 are preferably springs.

[0045] Under normal conditions, there is a preset gap between the second magnetic chuck 31 and the end wall of the trash can 3. When the trash can 3 moves towards the first magnetic chuck 25, the second magnetic chuck 31 abuts against the first magnetic chuck 25 and compresses the elastic element 5, reducing the preset gap. The elastic element 5 can act as a buffer and reduce noise, preventing damage to the first magnetic chuck 25. In addition, this embodiment can also adjust the size of the preset gap by adjusting the depth of the locking fastener 6 inserted into the end wall of the trash can 3, that is, adjusting the longitudinal position of the second magnetic chuck 31. This helps to absorb assembly and production errors, ensuring that the first magnetic chuck 25 and the second magnetic chuck 31 can abut against each other before magnetic attraction, thus avoiding impact caused by the first magnetic chuck 25 attracting the second magnetic chuck 31 instantaneously when energized when the first magnetic chuck 25 and the second magnetic chuck 31 are a certain distance apart.

[0046] Combination Figure 2 and Figure 3This embodiment also includes a positioning detection component 7, which includes a positioning detector 71 and a sensing element 72. The positioning detector 71 is mounted on the bracket 2. Preferably, the positioning detector 71 is mounted on the fixed base 24 and positioned to one side of the first magnetic suction member 25. The sensing element 72 is mounted on the trash can 3 and positioned to one side of the second magnetic suction member 31. The sensing element 72 can move with the trash can 3. The positioning detector 71 and the sensing element 72 are correspondingly positioned. The positioning detector 71 is electrically connected to the control module. The sensing element 72 can trigger the positioning detector 71 to send a positioning signal to the control module. Subsequently, the control module controls the first magnetic suction member 25 to be energized, and the first magnetic suction member 25 is magnetically connected to the second magnetic suction member 31. In this embodiment, the positioning detector 71 is preferably a Hall sensor, and the sensing element 72 is preferably a magnet; in other embodiments, the positioning detector 71 can be a pressure sensor, a proximity switch, etc.

[0047] Combination Figure 2 and Figure 3 The guide groove 22 has two limiting blocks 23 at one end near the first magnetic suction member 25. The two limiting blocks 23 are respectively located on both sides of the guide groove 22 away from its inlet and outlet. The limiting blocks 23 can abut against the end wall of the trash can 3 to restrict the longitudinal position of the trash can 3 into the guide groove 22 and prevent damage to the second magnetic suction member 31. The limiting blocks 23 can be fixed posts protruding from the bottom of the guide groove 22 or fixed blocks protruding from the wall of the guide groove 22. This embodiment takes the former as an example.

[0048] The mounting plate 1 is provided with two slide rail assemblies 11. The slide rail assemblies 11 extend longitudinally, and the bracket 2 is simultaneously mounted on both slide rail assemblies 11. The slide rail assemblies 11 are conventional technology in the art, and their specific structure will not be described in detail here.

[0049] The trash can module 10 also includes a movement detection component 8, which includes a trigger 81 and two detection sensors 82. The two detection sensors 82 are arranged on the mounting plate 1 along the movement direction of the bracket 2, and are positioned below the bracket 2. The trigger 81 is located on the bottom wall of the bracket 2 and positioned between the two detection sensors 82, moving back and forth between them. The detection sensors 82 are electrically connected to the control module, and are preferably photoelectric sensors.

[0050] Trigger 81 can trigger the detection sensor 82 to send a movement detection signal to the control module. The counting unit of the control module increments the count by one, thereby calculating and recording the number of reciprocating movements of the bracket 2 and the garbage bin 3, and recording their current movement position.

[0051] Combination Figure 2 and Figure 3The drive assembly 4 includes a motor 41 and an eccentric linkage mechanism. The motor 41 drives the bracket 2 to reciprocate linearly through the eccentric linkage mechanism. The eccentric linkage mechanism is a mechanism that can convert rotational motion into linear reciprocating motion.

[0052] Specifically, the eccentric linkage mechanism includes an eccentric rotating block 42, an eccentric shaft 43, a swing link 44, and a push block 45. The eccentric rotating block 42 is mounted on the drive shaft of the motor 41, and the eccentric shaft 43 is mounted on the eccentric rotating block 42, with the eccentric shaft 43 being eccentrically positioned to the drive shaft of the motor 41. The push block 45 is fixedly mounted on the bracket 2, and a connecting shaft is provided on the push block 45. The two ends of the swing link 44 are hinged to the eccentric shaft 43 and the connecting shaft, respectively. The motor 41 drives the eccentric rotating block 42 to rotate, which in turn drives the bracket 2 to reciprocate longitudinally via the eccentric shaft 43 and the swing link 44.

[0053] In this embodiment, different strokes and frequencies can be achieved by adjusting the eccentricity of the eccentric shaft 43 and the size of the swing link 44.

[0054] See Figure 4 and combined Figure 1 The nucleic acid testing equipment provided in this embodiment includes a reagent module 20, a sample module 30, a pipette tip module 40, an incubation and interpretation module 50, a transport module 60, an auxiliary reagent module 70, a sample pretreatment module 80, and a waste bin module 10 as described in the above embodiment.

[0055] In this embodiment, the sample pretreatment module 80 and the sample module 30 are both located on the first side of the transport module 60, the incubation and interpretation module 50 and the pipette tip module 40 are both located on the second side of the transport module 60, the auxiliary reagent module 70 is located between the incubation and interpretation module 50 and the pipette tip module 40, the reagent module 20 is located at the end of the transport module 60, and the waste bin module 10 is located below the sample module 30, with the waste inlet of the waste bin module 10 located close to the transport module 60. The reagent module 20 contains reaction tubes, the sample module 30 contains sample tubes, and the pipette tip module 40 contains disposable pipette tips.

[0056] The pull-out and push-in direction of trash can 3 is set on the side of the nucleic acid testing equipment, which has the advantage of being more labor-saving from an ergonomic point of view. From the perspective of the equipment's usage scenarios, it can save the vertical dimension of the equipment, making the equipment structure more compact.

[0057] In other embodiments, the positions of the various modules can be adjusted according to actual needs, and no restrictions are imposed here.

[0058] In summary, this utility model, by setting the first magnetic suction member 25 and the second magnetic suction member 31 to magnetically connect, facilitates fixing the trash can 3 to the bracket 2 and prevents the trash can 3 from moving relative to the bracket 2 during linear reciprocating movement. On the one hand, this helps to ensure that the trash can 3 is always on the bracket 2 and avoids being thrown out; on the other hand, it helps to avoid noise caused by the movement of the trash can 3 relative to the bracket 2. By setting the second magnetic suction member 31 to flexibly connect with the trash can 3, it not only helps the two magnetic suction members to adapt to the ground surface but also has a buffering effect.

[0059] Finally, it should be emphasized that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
