Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a sample storage device and a sample analysis system. Background Technology

[0002] Existing sample analyzers typically have an infeed area and a retrieval area for storing sample racks. The number of sample racks that can be stored in these areas is limited, preventing the pre-positioning of more racks. When more racks are needed, it's necessary to wait for the samples in the previously placed racks to be tested and removed before manually inserting new racks. Further, if increased sample rack storage capacity is required, the first option is to expand the storage space beyond the existing equipment, but this makes the equipment bulky. The second option is to connect with other equipment. In this case, the common practice is to build a pipeline system allowing multiple models to work together. This involves adding an infeed mechanism, which includes both infeed and retrieval areas, responsible for transporting and retrieving sample racks. However, the infeed mechanism has a complex structure and a large footprint, similarly contributing to the overall complex structure and large footprint of the equipment. This affects the applicability of the equipment, preventing the sample analyzer from simultaneously achieving large sample rack storage space and high applicability.

[0003] As can be seen from the above, existing technologies have the problem that sample analysis equipment cannot simultaneously accommodate large sample rack storage space and high applicability. Summary of the Invention

[0019] Furthermore, there are two second abutting parts, two second synchronous belts, and two second guide rods. The two second abutting parts, two second synchronous belts, and two second guide rods are spaced apart and symmetrically arranged, and the two second abutting parts abut against the two ends of the sample holder respectively.

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0046] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0047] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0048] To address the problem that existing sample analysis equipment cannot simultaneously accommodate large sample rack storage space and high applicability, this invention provides a sample storage device and a sample analysis system. The sample storage device is included in the following description of the sample analysis system.

[0049] like Figures 1 to 15 As shown, the sample storage device includes an injection storage chamber 200 and an output recovery chamber 300, which are respectively disposed on both sides of the sample analyzer 100 and detachably connected to the sample analyzer 100. The injection storage chamber 200 and the output recovery chamber 300 each have a storage slot for storing sample racks 400. The injection storage chamber 200 includes a first conveying component 210 and a second conveying component 220. The second conveying component 220 is disposed at one end of the storage slot of the injection storage chamber 200. The first conveying component 210 is used to convey the sample rack 400 to the second conveying component 220, and the second conveying component 220 is used to convey the sample rack 400 to the sample analyzer 100. The output recovery chamber 300 includes a third conveying component 310, which is used to convey the sample rack 400 that has been tested by the sample analyzer 100 from one end of the storage slot to the other end.

[0050] The technical solution of this invention provides a detachable sample storage chamber 200 and a sample return chamber 300 on both sides of the sample analyzer 100. This increases the sample rack storage space while allowing for flexible disassembly when a large storage space is not needed, ensuring high site adaptability. Furthermore, the sample storage chamber 200 and the sample return chamber 300 are equipped with storage slots and the sample rack is transported via a conveying assembly, eliminating the need for a separate sample transfer mechanism. This greatly simplifies the overall structure of the sample analysis equipment, reduces the floor space required, and further ensures the applicability of the sample analysis equipment, achieving both a large sample rack storage space and high applicability.

[0051] In this embodiment, the storage slot extends along a first direction, and the conveying direction of the second conveying assembly 220 is a second direction, which is perpendicular to the first direction. Specifically, the first direction is... Figure 1 The front and back directions, the second direction is Figure 1 The left and right directions in the middle, that is, the arrangement direction of the sample storage chamber 200, the sample analyzer 100 and the sample recovery chamber 300.

[0052] In this embodiment, as Figure 2 and Figure 13As shown, the sample injection storage chamber 200 has a first storage slot 290, and the sample retrieval chamber 300 has a second storage slot 360. To ensure the overall compactness of the sample analysis system, both the sample injection storage chamber 200 and the sample retrieval chamber 300 are cuboid structures, with their long sides adjacent to the sample analyzer 100 and their lengths matching those of the sample analyzer 100, resulting in a compact and regular overall arrangement of the sample analysis system. It can be understood that the first direction is the length direction of the sample injection storage chamber 200 and the sample retrieval chamber 300; therefore, the storage slots are also rectangular. Furthermore, the length of the sample rack 400 matches the width of the storage slot. When multiple sample racks 400 are stored in the storage slot, the multiple sample racks 400 are arranged along the first direction, thereby maximizing the storage capacity of the sample racks 400.

[0053] In this embodiment, the second delivery component 220 is disposed at the first end of the storage slot of the sample storage chamber 200, i.e. Figure 1 The front end is the first end, and correspondingly, the rear end is the second end. That is to say, in Figure 2 In the middle, the sample holder 400 is located at the second end of the storage slot, in Figure 3 In the sample rack 400, the sample rack 400 is located at the first end of the storage tank. Similarly, the first and second ends of the sample return chamber 300 are also the front and rear ends.

[0054] In this embodiment, the sample storage chamber 200 and the sample recovery chamber 300 can be connected to the sample analyzer 100 by means of snap-fit ​​connection, magnetic connection, bolt connection, etc., and no limitation is made here.

[0055] like Figures 2 to 11 As shown, the sample injection storage chamber 200 also includes a first base 240, a first support 250, a first carrier plate 270, and a first housing 280. The first housing 280 is fastened to the first base 240 to form an accommodating space, and most of the components of the sample injection storage chamber 200 are located within the accommodating space. The top of the first housing 280 has a rectangular opening, and a first storage groove 290 is formed between the first carrier plate 270 and the first housing 280, that is, the first carrier plate 270 is the bottom surface of the first storage groove 290. The first carrier plate 270 is located above the first base 240 and spaced apart from the first base 240, and the first delivery assembly 210 is located between the first carrier plate 270 and the first base 240. The first support 250 is disposed at the first end of the first base 240, the first end of the first carrier plate 270 is connected and fixed to the first support 250, and the second end and the middle part are connected and fixed to the first base 240 through support columns.

[0056] like Figures 7 to 11As shown, the first conveying assembly 210 includes a first abutment 211, a first synchronous belt 212, and a first drive component 213. The first abutment 211 is connected and fixed to the first synchronous belt 212 and abuts against the sample holder 400.

[0057] The first driving component 213 is drivenly connected to the first synchronous belt 212 and is used to drive the first synchronous belt 212 to transport the sample rack 400. Specifically, the first synchronous belt 212 moves in a first direction. The first driving component 213 is located at the second end of the first base 240. A driven wheel is provided at the first end of the first base 240. A driving wheel is provided on the output shaft of the first driving component 213. The first synchronous belt 212 is sleeved on the driving wheel and the driven wheel and rotates under the drive of the first driving component 213.

[0058] Specifically, the first abutting member 211 includes a fixed base and an abutting section. The fixed base is connected and fixed to the first synchronous belt 212, specifically by fastening with a pressure plate and screws. The abutting section is disposed on the fixed base, and the abutting section first extends outward and then bends upward to pass over the first carrier plate 270, and then bends inward again to extend above the first storage slot 290, thereby abutting against the sample holder 400, and driving the sample holder 400 to move along the first direction under the drive of the first driving member 213.

[0059] Furthermore, such as Figures 7 to 11 As shown, the first conveying assembly 210 also includes a first guide rod 214. The extension direction of the first guide rod 214 is parallel to the conveying direction of the first synchronous belt 212, and the first abutment 211 is movably sleeved on the first guide rod 214. Specifically, the first guide rod 214 extends along a first direction, and the fixing seat of the first abutment 211 is movably sleeved on the first guide rod 214. A vertical plate is provided at the second end of the first base 240, and the two ends of the first guide rod 214 are respectively connected and fixed to the first bracket 250 and the vertical plate. Through the above arrangement, the conveying stability of the first conveying assembly 210 can be improved, ensuring the stable movement of the sample rack 400 within the first storage tank 290.

[0060] In this embodiment, there are two first abutment members 211, two first synchronous belts 212, and two first guide rods 214. These two first abutment members 211, two first synchronous belts 212, and two first guide rods 214 are spaced apart and symmetrically arranged. The two first abutment members 211 abut against both ends of the sample holder 400. It can be understood that the abutment sections of the two first abutment members 211 are bent towards each other, thereby abutting against both ends of the sample holder 400. This arrangement ensures that the sample holder 400 can be transported with uniform force, preventing deviation during movement and affecting the sample loading efficiency of the sample holder 400.

[0061] Furthermore, such as Figure 7As shown, to more rationally position the first driving member 213, the first conveying assembly 210 further includes a first transfer connector 215. The first transfer connector 215 is located at the second end of the first base 240 and outside the first driving member 213. The first driving member 213 is located between the two first synchronous belts 212, thus not occupying additional space. The first transfer connector 215 includes a rotating shaft and a rotating bracket. The rotating shaft is movably inserted through the rotating bracket in a second direction. The rotating shaft is fitted with three spaced synchronous pulleys. The synchronous pulley in the middle is driven to the drive wheel of the first driving member 213 via a synchronous belt. The two first synchronous belts 212 are respectively fitted onto the synchronous pulleys at both ends, so that the first driving member 213 can simultaneously drive the two first synchronous belts 212 to rotate.

[0062] like Figure 5 , Figures 8 to 11 As shown, the second conveying assembly 220 includes a first conveyor belt 221 and a second drive member 222. The second drive member 222 is drivenly connected to the first conveyor belt 221 and is used to drive the first conveyor belt 221 to convey the sample rack 400. Specifically, the conveying direction of the first conveyor belt 221 is the second direction.

[0063] like Figure 8 and Figure 10 As shown, to more rationally arrange the second conveying assembly 220, the second conveying assembly 220 also includes a second transfer connector 223. Specifically, synchronous pulleys are respectively provided at both ends of the first bracket 250, and the first conveyor belt 221 is sleeved on the two synchronous pulleys. The second transfer connector 223 includes a connecting wheel and a synchronous belt. The connecting wheel is coaxial with and spaced apart from one of the synchronous pulleys. The second drive member 222 is connected and fixed to the first bracket 250, and a drive wheel is provided on its output shaft. The drive wheel and the connecting wheel are driven and connected by the synchronous belt, so that the second drive member 222 drives the first conveyor belt 221 to rotate through the second transfer connector 223.

[0064] In this embodiment, the first housing 280 has an avoidance notch on the side near the sample analyzer 100. The avoidance notch is correspondingly provided with the first conveyor belt 221, so that the first conveyor belt 221 can transport the sample holder 400 to the sample analyzer 100.

[0065] like Figure 4 and Figure 7 As shown, the sample storage chamber 200 also includes a pushing component 230. The pushing component 230 is located on one side of the second transport component 220 and is also located on the first support 250. It is used to push the sample rack 400 on the second transport component 220 out of the storage slot. This arrangement assists in the transfer of the sample rack 400, ensuring that the sample rack 400 can smoothly enter the sample analyzer 100.

[0066] Specifically, such as Figures 5 to 6 , Figures 8 to 11 As shown, the pushing component 230 includes a push plate 231, a second conveyor belt 232, a third drive member 233, and a first slide rail mechanism 234. The push plate 231 is disposed on the first slide rail mechanism 234, which is connected and fixed to the second conveyor belt 232. The conveying direction of the second conveyor belt 232 is parallel to the conveying direction of the second conveying component 220. The sliding direction of the first slide rail mechanism 234 is perpendicular to the conveying direction of the second conveyor belt 232 and faces the second conveying component 220. The third drive member 233 is drivenly connected to the second conveyor belt 232 and is used to drive the push plate 231 to push the sample rack 400.

[0067] In this embodiment, the push plate 231 is horizontally positioned and its height is higher than that of the first conveyor belt 221. The conveying direction of the second conveyor belt 232 is the second direction, and the sliding direction of the first slide rail mechanism 234 is the first direction.

[0068] like Figure 6 As shown, the first slide rail mechanism 234 includes a first slide rail 2341, a first slider 2342, a seat 2343, and an elastic element 2344. A push plate 231 is disposed on the first slider 2342, the first slider 2342 is slidably connected to the first slide rail 2341, the seat 2343 is fixedly connected to the second conveyor belt 232, and the elastic element 2344 is connected to both the push plate 231 and the seat 2343, providing a force for the push plate 231 to slide towards the second conveying assembly 220.

[0069] In this embodiment, the elastic element 2344 is a spring. It can be understood that the spring in this embodiment is in a stretched state. The spring force is within a range that can both drive the push plate 231 to move towards the second conveying assembly 220 and prevent it from pushing the sample rack 400 on the first conveyor belt 221 in the first direction.

[0070] Furthermore, such as Figure 6 , Figures 8 to 9 as well as Figure 11As shown, a guide wheel 235 is provided at one end of the push plate 231, specifically at the end away from the clearance notch of the first housing 280. The push assembly 230 also includes guide members 236 corresponding to and spaced apart from the guide wheel 235. The guide members 236 are mounted on the first bracket 250 and have a guide ramp and a stop surface that cooperate with and are sequentially connected to the guide wheel 235. The guide ramp is closer to the clearance notch than the stop surface, and the guide ramp is inclined towards the second conveying assembly 220 along the conveying direction of the second conveyor belt 232. The stop surface is parallel to the second direction. Specifically, in the initial state, the guide wheel 235 abuts against the stop surface, and the stop surface forms a limiting stop on the guide wheel 235, thereby creating a gap between the push plate 231 and the first conveyor belt 221. When the guide wheel 235 moves from the stop surface to the guide ramp, it is no longer limited and stopped. Under the action of the elastic element 2344, the push plate 231 gradually moves inward. The guide wheel 235 contacts the guide ramp and rolls along it until it abuts against the side wall of the first bracket 250. This arrangement allows the push plate 231 to move more smoothly and stably, ensuring a proper pushing effect on the sample holder 400.

[0071] Specifically, when the first conveying assembly 210 conveys the sample holder 400 from the second end to the first end of the first storage tank 290, the sample holder 400 is located on the first conveyor belt 221. The push plate 231 is kept at a distance from the sample holder 400 by the limiting stop action of the guide wheel 235 and the stop surface of the guide member 236. The second driving member 222 drives the first conveyor belt 221 to rotate, thereby driving the sample holder 400 to move towards the sample analyzer 100 in the second direction. After the sample holder 400 moves a certain distance, the third drive component 233 drives the second conveyor belt 232 to rotate, causing the push plate 231 to move along the second direction. The guide wheel 235 moves from the stop surface to the guide slope. At this time, the guide wheel 235 is no longer limited and stops, and rolls along the guide slope. Under the action of the elastic component 2344, the push plate 231 moves inward synchronously to above the first conveyor belt 221. Then, the push plate 231 continues to move along the second direction and one end abuts against the end of the sample holder 400, thereby pushing the sample holder 400 out of the clearance notch and pushing it into the first storage slot 290, allowing the sample holder 400 to smoothly enter the sample analyzer 100. After the pushing of the sample holder 400 ends, the third drive component 233 drives the second conveyor belt 232 to rotate in the opposite direction, causing the push plate 231 to exit from above the first conveyor belt 221 and return to the state where the guide wheel 235 is limited and stopped by the stop surface. Further, as Figure 5 , Figures 9 to 11As shown, the pushing component 230 also includes a second slide rail 237 and a second slider 238 that are slidably connected. The second slider 238 is fixedly connected to the first slide rail mechanism 234, and the extension direction of the second slide rail 237 is parallel to the conveying direction of the second conveyor belt 232. It can be understood that the second slide rail 237 and the second slider 238 constitute the second slide rail mechanism. Specifically, the second slide rail 237 is disposed on the side wall of the first bracket 250 and extends along the second direction, and the second slider 238 is fixedly connected to the seat 2343, so that the first slide rail mechanism 234 can move with the second conveyor belt 232 and is also guided by the second slide rail mechanism, so that the push plate 231 on it can move more smoothly and stably, ensuring the pushing effect on the sample rack 400.

[0072] like Figures 13 to 15 As shown, the sample collection chamber 300 also includes a second base 320, a second support 330, a second carrier plate 340, and a second housing 350. The second housing 350 is fastened to the second base 320 to form an accommodating space, and most of the components of the sample collection chamber 300 are located within the accommodating space. The top of the second housing 350 has a rectangular opening, and a second storage groove 360 ​​is formed between the second carrier plate 340 and the second housing 350, that is, the second carrier plate 340 is the bottom surface of the second storage groove 360. The second carrier plate 340 is located above the second base 320 and is spaced apart from the second carrier plate 320. The third conveying assembly 310 is located between the second carrier plate 340 and the second base 320. The second support 330 is disposed at the first end of the second base 320, and the two ends and the middle part of the second carrier plate 340 are connected and fixed to the second base 320 by support columns.

[0073] like Figure 15 As shown, the third conveying assembly 310 includes a second abutment 311, a second synchronous belt 312, and a fourth drive member 313. The second abutment 311 is connected and fixed to the second synchronous belt 312 and abuts against the sample holder 400. The fourth drive member 313 is drivenly connected to the second synchronous belt 312 and is used to drive the second synchronous belt 312 to convey the sample holder 400. Specifically, the movement direction of the second synchronous belt 312 is the first direction. The fourth drive member 313 is located at the second end of the second base 320. A driven wheel is provided at the first end of the second base 320. A drive wheel is provided on the output shaft of the fourth drive member 313. The second synchronous belt 312 is sleeved on the drive wheel and the driven wheel, and rotates under the drive of the fourth drive member 313.

[0074] In this embodiment, the first driving component 213, the second driving component 222, the third driving component 233 and the fourth driving component 313 are all motors.

[0075] Specifically, in this embodiment, the structure and arrangement of the second abutment 311 are the same as those of the first abutment 211, and will not be described again here.

[0076] Furthermore, such as Figure 15 As shown, the third conveying assembly 310 also includes a second guide rod 314. The extension direction of the second guide rod 314 is parallel to the conveying direction of the second synchronous belt 312, and the second abutment 311 is movably sleeved on the second guide rod 314. Specifically, the second guide rod 314 extends along a first direction, and the fixing seat of the second abutment 311 is movably sleeved on the second guide rod 314. A vertical plate is provided at the second end of the second base 320, and the two ends of the second guide rod 314 are respectively connected and fixed to the second bracket 330 and the vertical plate. Through the above arrangement, the conveying stability of the third conveying assembly 310 can be improved, ensuring the stable movement of the sample rack 400 within the second storage tank 360.

[0077] In this embodiment, there are two second abutting members 311, two second synchronous belts 312, and two second guide rods 314. The two second abutting members 311, two second synchronous belts 312, and two second guide rods 314 are spaced apart and symmetrically arranged. The two second abutting members 311 abut against the two ends of the sample holder 400 respectively.

[0078] Furthermore, such as Figure 15 As shown, to more rationally position the fourth drive member 313, the third conveying assembly 310 also includes a third transfer connector 315. The third transfer connector 315 is located at the second end of the second base 320 and outside the fourth drive member 313, which is situated between the two second synchronous belts 312, thus not occupying additional space. The structural configuration of the third transfer connector 315 is the same as that of the first transfer connector 215, and will not be described again here.

[0079] In this embodiment, position sensors 260 are respectively provided at both ends of the storage tank to detect the position of the sample holder 400. Specifically, the position sensor 260 located at the first end of the storage tank is used to detect whether the sample holder 400 is present in the storage tank, while the position sensor 260 not located at the second end of the storage tank is used to detect whether the sample holder 400 has been conveyed onto the first conveyor belt 221 or to the second end of the storage tank. The position sensor 260 can be of the photoelectric sensing type, magnetic sensing type, etc.

[0080] like Figure 1 As shown, the present invention also provides a sample analysis system, including a sample analyzer 100 and the sample storage device described above. A sample inlet storage chamber 200 and a sample outlet recovery chamber 300 are respectively disposed on both sides of the sample analyzer 100 and detachably connected to the sample analyzer 100.

[0081] like Figure 1As shown, the sample analyzer 100 includes an analysis body 110 and a base, with the analysis body 110 mounted on the base. The base is provided with a sample inlet area 120 and a recovery area 130. The sample inlet area 120 corresponds to the second transport component 220 of the sample storage chamber 200, which transports the sample rack 400 to the sample inlet area 120. The first end of the second housing 350 has an clearance notch on the side near the sample analyzer 100, and the recovery area 130 corresponds to the clearance notch of the sample recovery chamber 300, thereby transporting the tested sample rack 400 into the sample recovery chamber 300.

[0082] like Figure 1 and Figure 12 As shown, the sample analyzer 100 includes a fourth conveying assembly 140, which is used to convey the tested sample rack 400 to the sample return chamber 300. Specifically, the fourth conveying assembly 140 is located at the first end of the return area 130 and includes a third conveyor belt 141 and a fifth drive member (not shown). The fifth drive member is driven to connect with the third conveyor belt 141, thereby driving the third conveyor belt 141 to rotate in a second direction.

[0083] Furthermore, in this embodiment, the sample analyzer 100 also includes a pushing component 230, which is disposed on one side of the fourth conveying component 140 and is used to push the sample rack 400 on the fourth conveying component 140 into the sample return chamber 300. Specifically, the specific structural configuration of the pushing component 230 is the same as described above, and will not be repeated here. Through the above configuration, it plays an auxiliary pushing role in the transfer of the sample rack 400, ensuring that the sample rack 400 can smoothly enter the sample return chamber 300.

[0084] Furthermore, the sample analyzer 100 is also provided with a transport assembly in the sample introduction area 120 and the recovery area 130, so as to transport the sample rack 400 entering the sample introduction area 120 to the analysis body 110, and from the analysis body 110 to the fourth transport assembly 140.

[0085] In this embodiment, the sample analysis system also includes a controller, which is electrically connected to the sample analyzer 100, the sample storage chamber 200, and the sample return chamber 300. Specifically, the controller is electrically connected to each conveying component, the pushing component 230, and the position sensor 260, thereby receiving the position detection signal of the sample rack 400 from the position sensor 260, and then controlling the corresponding operation of each conveying component and the pushing component 230 to realize the conveying of the sample rack 400 from the sample storage chamber 200 to the sample analyzer 100, and from the sample analyzer 100 to the sample return chamber 300.

[0086] As can be seen from the above description, the above embodiments of the present invention achieve the following technical effects: by setting detachably connected sample inlet storage chamber 200 and sample outlet recovery chamber 300 on both sides of the sample analyzer 100, the sample rack storage space is increased, and it can be flexibly disassembled when a large storage space is not needed, ensuring high site applicability. Furthermore, the sample inlet storage chamber 200 and sample outlet recovery chamber 300 are provided with storage slots and the sample rack is transported through a conveying component, thereby eliminating the need for a separate sample transfer mechanism, greatly simplifying the overall structure of the sample analysis equipment, reducing the floor space, and further ensuring the applicability of the sample analysis equipment, achieving both a large sample rack storage space and high applicability.
