Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a waste collection device and an analyzer provided with the waste collection device. Background Art

[0002] Chemiluminescent immunoassay analyzers usually use consumables such as waste materials. Waste materials are used as reaction containers for samples, diluents, reagents, etc., and need to be discarded into a special waste bucket for recycling after use. However, during the test process, since the interval between discarding the cup is very short, and this type of equipment is usually designed with only one waste bucket, when the waste bucket is full and the waste needs to be taken out and dumped, it is necessary to either suspend the test operation of the equipment or clean up the waste that fell during the dumping of the waste bucket. Among them, if the test is suspended during the dumping of the waste bucket, it is very easy to cause abnormal test results and even require retesting; and if the waste is allowed to fall and be cleaned during the dumping of the waste bucket, it is very easy to cause the inside and surrounding of the equipment to be contaminated by samples, diluents, reagents, etc., and there are health and safety hazards.

[0003] In this regard, the invention patent application with the publication number CN110015522A discloses a waste collection device, including a waste bin, an inlet and a control circuit board, the number of waste bins is at least two and the openings are upward, the number of inlets is more than one, a channel is provided between the inlet and the waste bin, each inlet has a separate channel leading to each waste bin, a cover plate is provided above the waste bin, a plurality of through holes are provided on the cover plate, the channel is connected to the through holes through a fixture, a laser sensor is provided on the inner side of the cover plate, a bottom plate is provided below the waste bin, a motor, a cam and a pressure sensor are provided on the bottom plate, the motor is connected to the cam, an outer plate is provided around the waste bin, a proximity sensor is provided on the inner side of the outer plate, and the control circuit board is electrically connected to the laser sensor, the pressure sensor, the motor and the proximity sensor respectively. When the laser sensor detects that the waste in the current waste bin is full and the pressure sensor detects that the weight of the current waste bin is full, the control circuit board 17 controls the inlet to cut off the connection with the current waste bin, so that the waste entering the inlet enters another waste bin through another channel, so as to avoid the need to suspend the equipment when replacing the full-loaded waste bin. However, the waste collection device has the disadvantages of over-reliance on electronic components. When the electronic components fail (such as laser sensors, pressure sensors, proximity sensors, and any of the inlets), waste will fall around the waste bin, resulting in poor reliability, high cost, and increased difficulty in programming the equipment control circuit board. Summary of the invention

[0004] In order to solve the above problems, the main purpose of the utility model is to provide a waste collection device with high reliability and low production cost.

[0005] Another object of the utility model is to provide an analyzer provided with the above waste collection device.

[0006] In order to achieve the main purpose of the utility model, the utility model provides a waste collection device, including a waste barrel installation frame, a main barrel and a sub-barrel, the waste barrel installation frame includes a main body, the main body has a holding chamber and a feed port, the main barrel and the sub-barrel can be detachably arranged in the holding chamber, the main barrel has a first recovery port, and the sub-barrel has a second recovery port, wherein the waste collection device also includes a mechanical drive mechanism for driving the sub-barrel to move from a first position to a second position, and the mechanical drive mechanism is connected to the sub-barrel through a connecting piece; when the main barrel and the sub-barrel are both placed in the holding chamber, the first recovery port is located directly below the feed port, and the sub-barrel is located in the first position; when the main barrel is pulled out of the holding chamber, the mechanical drive mechanism drives the sub-barrel to move to the second position, so that the second recovery port is located directly below the feed port.

[0007] As can be seen from the above, through the design of the waste collection device, when the main barrel and the sub-barrel are both placed in the containing chamber, the sub-barrel is located in the first position, and the main barrel plays a major role in recovery, so that the waste dropped from the feed port falls into the main barrel; when the main barrel is full of waste and is taken out from the containing chamber and dumped, the main barrel releases the restriction on the mechanical drive mechanism, so that the mechanical drive mechanism can automatically drive the sub-barrel to move to the second position, so that the sub-barrel is located directly below the feed port. At this time, the waste dropped from the feed port falls into the sub-barrel, and the sub-barrel temporarily replaces the main barrel to recycle the waste during the dumping of the main barrel. Therefore, the analyzer provided with the waste collection device does not need to suspend testing during the dumping of the main barrel, thereby ensuring that the test results are accurate and there is no need to retest; in addition, since the sub-barrel is driven by a mechanical drive mechanism with a purely mechanical structure, the reliability of the waste collection device is effectively improved, the production cost is reduced, and there is no need to program the mechanical drive mechanism with a variety of electronic components.

[0008] A further solution is that the main body includes a bottom plate, and the main barrel and the sub-barrel are located on the bottom plate; the mechanical drive mechanism is arranged in a chassis located below the bottom plate, and the mechanical drive mechanism includes a guide rail module and a spring member, and the bottom plate is provided with a long strip through hole parallel to the guide rail module, and the connecting member is connected to the slider of the guide rail module through the long strip through hole; the first end of the spring member is connected to the connecting member, and the second end of the spring member is fixedly connected to the first hook portion arranged in the chassis, and the spring member can force the connecting member to drive the sub-barrel to move to the second position; the spring member is a tension spring or a compression spring.

[0009] As can be seen from the above, the rail module guides the movement of the connecting member, so that the sub-barrel mounted on the connecting member can be switched between the first position and the second position stably and reliably; the spring member stores energy when the sub-barrel is moved to the first position, and releases its own elastic potential energy when the main barrel is pulled out of the accommodating chamber, so as to drive the connecting member to drive the sub-barrel to move to the second position; the type of spring member can be changed according to actual usage requirements, installation space, etc., so that the spring member can reliably drive the connecting member to move.

[0010] A preferred solution is that the mechanical drive mechanism includes two sets of guide rail modules, two spring members, two first hook parts, and the deformation direction of the spring member is parallel to the extension direction of the guide rail module.

[0011] It can be seen from the above that this design is conducive to the mechanical drive mechanism to drive the sub-barrel to move more smoothly.

[0012] Another preferred solution is that the connecting member includes a sub-barrel mounting portion and a fixing frame arranged in the chassis and connected to the slider, the sub-barrel mounting portion is provided with a placement groove for placing the sub-barrel, the fixing frame has a fixing portion and a second hook portion, the fixing portion passes through the long strip through hole and is connected to the sub-barrel mounting plate arranged above the bottom plate, and the second hook portion is connected to the first end of the spring member.

[0013] As can be seen from the above, the connection member is set as the auxiliary barrel mounting part and the fixing frame, so that the assembly between the connection member and the slider and the spring member of the guide rail module is more convenient, and the structure is more optimized and reasonable. The fixing part can ensure the reliability and convenience of the connection between the fixing frame and the auxiliary barrel mounting turntable, and the second hook part and the first hook part can ensure the reliability and convenience of the connection between the spring member and the fixing frame and the waste barrel mounting frame.

[0014] A further solution is that a first limit block is further provided on the fixing frame; a second limit block is provided in the chassis, and when the auxiliary barrel is in the second position, the first limit block abuts against the second limit block.

[0015] As can be seen from the above, the provision of the first limit block and the second limit block enables the auxiliary barrel to stop accurately at the second position, so that the waste falling from the outlet can accurately fall into the auxiliary barrel located at the second position.

[0016] A further solution is that the connecting member also includes a connecting plate fixedly connected to the fixing frame, the second hook portion and the first limiting block respectively, and the connecting plate is connected to the slider of the guide rail module.

[0017] A further solution is that a baffle is provided on one side of the secondary barrel mounting plate close to the main barrel.

[0018] As can be seen from the above, the baffle can prevent the auxiliary barrel from escaping from the placement groove due to inertia when the connecting member drives the auxiliary barrel to move to the second position.

[0019] A further solution is that the main barrel and the sub-barrel are arranged side by side on the bottom plate along a direction parallel to the guide rail module, and the direction in which the main barrel and the sub-barrel enter the accommodating chamber is perpendicular to the extension direction of the guide rail module; the sub-barrel mounting plate is also provided with a guide portion protruding in the direction of entry of the main barrel, and the side of the guide portion close to the main barrel entering the accommodating chamber is an inclined surface, and the inclined surface gradually moves away from the placement position of the main barrel in the accommodating chamber from the direction in which the main barrel gradually leaves the accommodating chamber.

[0020] As can be seen from the above, by providing the guide part, the main barrel can be placed in the accommodating chamber more conveniently and easily operated, and the main barrel can better push the connecting member through the guide part to drive the sub-barrel to move to the first position.

[0021] A further solution is that the waste collecting device further comprises a waste port mounting frame and a pipeline, wherein a first end of the pipeline is connected to the waste port mounting frame, and a second end of the pipeline is connected to the feed port.

[0022] As can be seen from the above, the pipeline is reliably connected to the analyzer equipped with the waste collection device through the waste port mounting frame, and the pipeline is used to guide the discarded waste to the outlet, so that the waste falls from the outlet into the main barrel or the auxiliary barrel.

[0023] In order to achieve another object of the utility model, the utility model provides an analyzer, which includes the waste collection device as mentioned above.

[0024] As can be seen from the above, by setting up the above-mentioned waste collection device, the analyzer does not need to suspend testing when recycling waste, and ensures the accuracy of test results without the need for retesting; at the same time, since the waste collection device switches from the main barrel to the auxiliary barrel to receive waste through a mechanical drive mechanism with a purely mechanical structure to drive the auxiliary barrel, the reliability of the waste collection device is effectively improved, the production cost is reduced, and there is no need to program and control the mechanical drive mechanism with a variety of electronic components.

[0038] Analyzer Example

[0039] Combination Figure 1 and Figure 2 The analyzer 100 includes a frame 101, a turntable 102, a first manipulator 103, a second manipulator 104 and a waste collection device 105. The turntable 102 is rotatably mounted on the workbench of the frame 101 around its own rotation axis; the first manipulator 103 and the second manipulator 104 are respectively used to transfer the waste (such as reaction cups, gun tips, etc.) on the turntable 102 after the test to the first cup-dropping opening 411 or the second cup-dropping opening 412; specifically, the first manipulator 103 and the second manipulator 104 have different action paths - the first manipulator 103 can rotate around its installation axis to drop the waste into the first cup-dropping opening 411, and the second manipulator 104 moves along a straight line to drop the waste into the second cup-dropping opening 412.

[0040] The waste enters the waste collection device 105 through the first cup-discharging port 411 or the second cup-discharging port 412. The waste collection device 105 is preferably arranged in the analyzer 100. The waste collection device 105 includes a waste barrel mounting frame 1, a main barrel 21, a secondary barrel 22, a mechanical drive mechanism 3, a waste port mounting frame 41 and a pipeline 42. Among them, the waste port mounting frame 41 and the pipeline 42 can be used as components of the waste collection device 105, and can also be inherent components of the analyzer 100.

[0041] Specifically, refer to Figure 2 The first cup-discarding port 411 or the second cup-discarding port 412 is respectively arranged on the top of the waste port mounting frame 41 and respectively connected to the first end of the pipe 42. The second end of the pipe 42 is connected to the feed port 112 of the waste collection device 105, so that the discarded waste can be gathered from the cup-discarding port through the pipe 42 to the same inlet-the feed port 112.

[0042] Combination Figure 3 The waste barrel installation frame 1 includes a body 11 and a bottom plate 12, wherein the body 11 has a receiving chamber 111, the opening 1111 of which is preferably located on the side of the body 11, and the receiving chamber 111 is used to accommodate the main barrel 21 and the auxiliary barrel 22. A feed port 112 is provided at the top of the body 11, and the feed port 112 is communicated with the receiving chamber 111, so that the waste entering through the feed port 112 can fall into the main barrel 21 or the auxiliary barrel 22 located below it.

[0043] Combination Figure 4 The chassis 12 is installed below the bottom plate 113 of the body 11 , and the chassis 12 has a receiving cavity 121 .

[0044] The top of the main barrel 21 has a first recycling port 211, and the main barrel 21 can be detachably placed in the receiving chamber 111 of the main body 11. The main barrel 21 plays a major role in recycling discarded waste. The top of the auxiliary barrel 22 is provided with a second recycling port 221, and the auxiliary barrel 22 can be detachably placed in the receiving chamber 111 and is detachably connected to the mechanical drive structure through a connecting member 31. The mechanical drive mechanism 3 is used to drive the auxiliary barrel 22 to move between the first position and the second position.

[0045] When the main barrel 21 and the auxiliary barrel 22 are both placed in the receiving chamber 111, the first recovery port 211 is located directly below the feed port 112, and the auxiliary barrel 22 is located at the first position (such as Figure 5 When the main barrel 21 is withdrawn from the containing chamber 111 and the auxiliary barrel 22 is placed on the connecting member 31, the mechanical driving mechanism 3 drives the auxiliary barrel 22 to move to the second position, so that the second recovery port 221 is located directly below the feed port 112 (as shown in FIG. Figure 6At this time, the auxiliary barrel 22 recycles the discarded waste.

[0046] Preferably, the volume ratio of the main barrel 21 to the auxiliary barrel 22 is greater than or equal to 3:1, so as to reduce the number of times the waste in the main barrel 21 is dumped, and ensure that the auxiliary barrel 22 has sufficient capacity to recycle the waste during the dumping of the waste in the main barrel 21.

[0047] Combination Figure 3 and Figure 4 , the mechanical drive mechanism 3 is arranged in the accommodating chamber 121, and the mechanical drive mechanism 3 includes a guide rail module 32 and a spring member 33. Preferably, the guide rail module 32 includes two guide rails arranged in parallel and a slider 321 slidably connected to the guide rails. The connecting member 31 has a sub-barrel mounting portion 311, and preferably, the sub-barrel mounting portion 311 is formed with a placement groove 3111, so that the sub-barrel 22 can be detachably placed in the placement groove 3111. Furthermore, a baffle 3112 is provided on one side of the sub-barrel mounting portion 311 close to the main barrel 21, and the baffle 3112 can prevent the sub-barrel 22 from escaping from the placement groove 3111 due to inertia when the connecting member 31 drives the sub-barrel 22 to move to the second position.

[0048] Preferably, the connecting member 31 further comprises a fixing frame 312. The fixing frame 312 is used to connect the slider 321 of the guide rail module 32 and the auxiliary barrel mounting portion 311. The fixing frame 312 comprises a connecting plate 3120, a fixing portion 3121 and a second hook portion 3122, wherein the connecting plate 3120 and the second hook portion 3122 are located in the accommodating cavity 121 of the chassis 12 of the waste barrel mounting frame 1; the connecting plate 3120 is respectively connected to the fixing portion 3121 and the second hook portion 3122, and the connecting plate 3120 is fixedly connected to the slider 321 of the guide rail module 32. In this embodiment, there are two second hook portions 3122, which are respectively arranged on both sides of the connecting plate 3120 along the moving direction of the guide rail module 32, and there are four fixing portions 3121, which are also respectively arranged on both sides of the connecting plate 3120 along the moving direction of the guide rail module 32, two on each side, and the second hook portion 3122 is located between the two fixing portions 312 on the same side. The fixing portion 3121 is used to connect with the auxiliary barrel mounting portion 311, and the second hook portion 3122 is used to connect with the first end of the spring member 33. In addition, the waste barrel mounting frame 1 also has two first hook portions 122 opposite to the second hook portion 312, the first hook portion 122 is formed in the accommodating cavity 121 of the chassis 12, and the first hook portion 122 is connected to the second end of the spring member 33; preferably, the straight line where the first hook portion 122 and the second hook portion 312 connect the spring member 33 is parallel to the guide rail module 32.

[0049] Furthermore, the bottom plate 113 of the body 11 is provided with an elongated through hole 114 that penetrates the body 11, so that the accommodating cavity 121 is connected with the accommodating chamber 111 through the elongated through hole 114, and the elongated through hole 114 is parallel to the guide rail module 32. Most of the fixing frame 312 is located in the chassis 12, and the fixing portion 3121 extends upward along the connecting plate 3120 and extends from the bottom of the bottom plate 113 of the body 11 into the accommodating chamber 111 through the elongated through hole 114, thereby connecting with the auxiliary barrel mounting portion 311 located in the accommodating chamber 111 above the bottom plate. In this embodiment, the fixing portion 3121 extends to the accommodating chamber 111 and is bent to form a mounting plate, which has screw holes, and the auxiliary barrel mounting portion 311 is provided with corresponding screw holes, and the fixing portion 3121 and the auxiliary barrel mounting portion 311 are fixed by screw connection. By setting up the chassis 12 and setting most of the guide rail module 32, the spring component 33 and the fixing frame 312 inside the chassis 12 and outside the main body 11, it is possible to better prevent the guide rail module 32 and the spring component 33 from being contaminated, and will not cause any hindrance to the installation of the main barrel 21, thereby ensuring the smooth sliding of the connecting component 31 and enabling the spring component 33 to reliably drive the connecting component 31 to slide.

[0050] Furthermore, a first limit block 3123 is also provided on the fixing frame 312. A second limit block 34 is provided in the chassis 12 opposite to the first limit block 3123, and the first limit block 3123 and the second limit block 34 are located between the guide rail module 321. When the connecting member 31 of the mechanical driving structure drives the auxiliary barrel 22 to move to the second position, the first limit block 3123 abuts against the second limit block 34. The cooperation of the first limit block 3123 and the second limit block 34 can accurately limit the auxiliary barrel 22 to stop at the second position, so that the waste dropped from the feed port 112 can accurately fall into the auxiliary barrel 22 located at the second position.

[0051] It should be noted that in other embodiments, the connecting member 31 can be directly connected to the auxiliary barrel 22 and the slider. By reasonably setting the length of the guide rail of the guide rail module 321 or the relative position of the first hook portion 122 and the slider, the auxiliary barrel 22 can slide just below the feed port after the main barrel 21 is pulled out.

[0052] In this embodiment, the spring member 33 is a tension spring, and the spring member 33 is used to drive the connecting member 31 to drive the auxiliary barrel 22 to move to the second position through its own elastic potential energy. When the connecting member 31 and the auxiliary barrel 22 are pushed to the first position by the main barrel 21, the tension spring is stretched to store energy, and when the main barrel 21 is pulled out of the accommodating chamber 111, the tension spring releases its own elastic properties to contract, thereby driving the connecting member 31 to drive the auxiliary barrel 22 to move to the second position.

[0053] Of course, in other embodiments, the spring member 33 may also be a compression spring. When the spring member 33 is a compression spring, when the connecting member 31 and the auxiliary barrel 22 are pushed to the first position by the main barrel 21, the tension spring is compressed to store energy; when the main barrel 21 is pulled out of the accommodating chamber 111, the tension spring releases its elastic properties to stretch, thereby driving the connecting member 31 to drive the auxiliary barrel 22 to move to the second position. It can be seen that the type of the spring member 33 can be changed according to actual use requirements, installation space, etc., so that the spring member 33 can reliably drive the connecting member 31 to move.

[0054] In other embodiments, the main barrel 21 and the auxiliary barrel 22 are distributed along the depth direction of the accommodation chamber 111, and correspondingly, the guide rail module 32 is parallel to the depth direction. However, this design is not convenient for cleaning the auxiliary barrel 22. It can be seen that the distribution arrangement of the main barrel 21 and the auxiliary barrel 22 can be adjusted according to the overall layout of the analyzer 100 in which the waste collection device 105 is installed, so as to ensure that the analyzer 100 can install and accommodate the waste collection device 105.

[0055] Preferably, in this embodiment, the main barrel 21 and the auxiliary barrel 22 are arranged side by side on the bottom plate 113 in a direction parallel to the guide rail module 32, and the direction in which the main barrel 21 and the auxiliary barrel 22 enter the receiving chamber 111 is perpendicular to the extension direction of the guide rail module 32; preferably, the auxiliary barrel installation portion 311 is also provided with a guide portion 3113 protruding in the direction in which the main barrel 21 enters the receiving chamber 111. The side of the guide portion 3113 close to the main barrel 21 entering the receiving chamber 111 is an inclined surface, and the inclined surface gradually moves away from the placement position of the main barrel 21 in the receiving chamber 111 from the direction in which the main barrel 21 gradually leaves the receiving chamber 111; so that the main barrel 21 can always abut against the inclined surface when entering the receiving chamber 111, and push the auxiliary barrel 22 to move to the first position. The setting of the guide portion 3113 makes it more convenient and easy to operate when placing the main barrel 21 in the receiving chamber 111 of the body 11, and the auxiliary barrel 22 can be driven to move to the first position through the guide portion 3113 while installing the main barrel 21.

[0056] The following is a brief description of the process of the analyzer 100 recovering discarded waste:

[0057] First, the two waste port mounting racks 41 in this embodiment are installed at different positions on the rack 101, and the first manipulator 103 and the second manipulator 104 are also located at different positions on the rack 101. When it is necessary to discard the waste, the first manipulator 103 grabs the waste after completing the function on its own motion trajectory and throws it into the corresponding cup-discharging port 411 of the first waste port mounting rack 41, and then the waste enters the corresponding pipe 42 through the cup-discharging port 411, and slides out of the feed port 112 of the body 11 of the waste bucket mounting frame 1 through the pipe 42; and / or the second manipulator 104 grabs the waste after completing the function on its own motion trajectory and throws it into the corresponding cup-discharging port 412 of the first waste port mounting rack 41, and then the waste enters the corresponding pipe 42 through the cup-discharging port 412, and slides out of the feed port 112 of the body 11 of the waste bucket mounting frame 1 through the pipe 42.

[0058] When the main barrel 21 and the sub-barrel 22 are simultaneously placed in the accommodating chamber 111 of the main body 11 (at this time, the first recovery port 211 of the main barrel 21 is located directly below the feed port 112, the sub-barrel 22 is located at the first position, and the second recovery port 221 of the sub-barrel 22 is staggered with the feed port 112, and the elastic member is in an energy storage state), the waste falling from the feed port 112 of the main body 11 falls into the main barrel 21.

[0059] When the main barrel 21 is full of discarded waste, the main barrel 21 is pulled out of the containing chamber 111 from the opening 1111 of the containing chamber 111, so that the spring member 33 of the mechanical drive mechanism 3 releases its own elastic potential energy to drive the connecting member 31 and the auxiliary barrel 22 thereon to move to the second position until the first limit block 3123 of the fixing frame 312 is adjacent to the second limit block 34 on the chassis 12; at this time, the auxiliary barrel 22 is in the second position, and the second recovery port 221 of the auxiliary barrel 22 is located directly below the feed port 112, and the waste falling from the feed port 112 of the main body 11 falls into the auxiliary barrel 22 for recovery, so that when the waste in the main barrel 21 is dumped, the analyzer 100 does not need to pause the test.

[0060] After the waste in the main barrel 21 is dumped, the main barrel 21 is pushed back into the original position from the opening 1111 of the accommodating chamber 111. In the process of the main barrel 21 being pushed into the accommodating chamber 111, the wall of the main barrel 21 contacts the guide portion 3113 of the sub-barrel mounting portion 311, and the sub-barrel mounting portion 311 and the sub-barrel 22 thereon are pushed to the second position through the guide portion 3113. When the main barrel 21 is in place, the first recovery port 211 of the main barrel 21 is located directly below the feed port 112, so that the waste dropped from the feed port 112 of the main body 11 falls back into the main barrel 21, and the sub-barrel 22 is confined to the second position, and the spring member 33 completes the re-energy storage.

[0061] In summary, it can be seen that through the design of the waste collection device 105, when the main barrel 21 and the sub-barrel 22 are both placed in the receiving chamber 111, the main barrel 21 can force the mechanical drive mechanism 3 to drive the sub-barrel 22 to move to the first position with its back to the feed inlet 112, so that the waste dropped from the feed inlet 112 falls into the main barrel 21, and at this time the main barrel 21 plays a major role in recycling; when the main barrel 21 is full of waste and is taken out and poured out from the receiving chamber, the main barrel 21 releases the restriction on the mechanical drive mechanism 3, so that the mechanical drive mechanism 3 can automatically drive the sub-barrel 22 to move to the second position, so that the sub-barrel 22 is located in the feed inlet 112. Directly below the material port 112, the waste material dropped from the material port 112 falls into the auxiliary barrel 22, and the auxiliary barrel 22 temporarily replaces the main barrel 21 to recycle the waste material during the pouring of the main barrel 21. Therefore, the analyzer 100 does not need to suspend the test during the pouring of the main barrel 21, thereby ensuring that the test results are accurate and there is no need to retest. In addition, since the auxiliary barrel 22 is driven by the mechanical drive mechanism 3 with a purely mechanical structure, the reliability of the waste collection device 105 is effectively improved, the production cost is reduced, and there is no need to program the mechanical drive mechanism 3 with a variety of electronic components.
