Description

Technical Field

[0001] The utility model relates to the technical field of sample injection devices for in vitro diagnostic equipment, in particular to an assembly line track sample injection module. Background Art

[0002] The assembly line system for in vitro diagnostic equipment primarily utilizes conveyor tracks to connect various stand-alone testing devices in series. The assembly line automatically schedules and allocates samples based on the test items, and automatically recovers samples after the measurement is completed, greatly reducing manual operation costs and improving the efficiency and automation of sample testing and processing. Currently, each in vitro diagnostic device includes a test track and a transport track, a track change unit located between the two, and an independently set emergency sample injection track. The transport tracks of multiple in vitro diagnostic devices are connected in sequence to form a conveyor assembly line. The sample rack is transported to the test track for sampling via the track change unit, and then returned to the transport track via the track change unit. Emergency samples that need to be queued for testing are sampled individually via the independently set emergency sample injection track, requiring manual assistance. This not only increases labor costs but also increases the risk of biological infection, which runs counter to the purpose of the assembly line, which is to reduce manual operation costs and improve sample testing and processing efficiency.

[0025] The following is a more detailed description of the embodiments of the present invention with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the invention after studying this specification. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The utility model provides a pipeline track sampling module, which comprises a track unit and a track changing unit.

[0027] The track unit includes a transport track 10 and a detection track 20, both of which are arranged in parallel. Each of the transport track 10 and the detection track 20 includes a sample rack conveyor belt 11, and guard plates 12 are provided on both sides of the sample rack conveyor belt 11 to prevent the sample racks from tipping over. The sample rack conveyor belt 11 can be formed by connecting multiple belt conveyors end to end, and is used to transport sample racks carrying test samples. The transport track 10 and the detection track 20 are two parallel tracks. The transport tracks 10 of different testing equipment are connected in sequence to form an assembly line, and the detection tracks 20 are also connected in sequence to form an assembly line. The sample racks mainly move on the transport track 10 and then enter the detection track 20 adjacent to a specific testing equipment. One side of the detection track 20 is generally equipped with a barcode scanning module 21 and a sampling mechanism of the testing equipment to enter the information barcode of the sample tube on the sample rack and sample. Its structure can refer to the relevant art. The guard plate 12 is provided with multiple notches to accommodate other equipment or facilitate the passage of sample racks, such as notches corresponding to the barcode scanning device, the support plate 31, the sample introduction handle 33, and the sample discharge handle 34.

[0028] The track changing unit includes a sample input cache module 30, a sample output cache module 40, a first track changing module and a second track changing module, which are arranged between the transport track 10 and the detection track 20. The four are arranged in parallel, and the first track changing module is arranged on the side of the sample input cache module away from the sample output cache module, and the second track changing module is arranged on the side of the sample output cache module away from the sample input cache module. Figure 1 The sample feeding module near a certain detection device, the transport track 10 and the detection track 20 are both partial schematic diagrams of the assembly line, a first track changing module is set on the right side of the sample feeding buffer module 30, and a second track changing module is set on the left side of the sample discharging buffer module 40. The first and second track changing modules are arranged on the left side of the sample discharging buffer module 40. Figure 1 Not shown in the figure.

[0029] The sample rack can first enter the sample loading buffer module 30 from the transport track 10 for caching and waiting. Multiple sample racks are sequentially transferred to the detection track 20 by the sample loading buffer module 30. After the sample rack is scanned and sampled on the detection track 20, it leaves the detection track 20 and enters the sample output buffer module 40 for temporary storage. After the test is completed, it is transported to the transport track 10 by the sample output buffer module 40 and then enters other detection equipment. When there is an emergency need, the sample rack waiting for scanning and sampling on the detection track 20 will be transferred from the detection track 20 via the second track change module and the transport track 10 to the sample loading buffer module 30 to re-queue. The sample rack requiring emergency treatment will be transported from the transport track 10 via the first track change module to the detection track 20, where scanning, sampling, and testing will be prioritized, thus enabling queue-jumping testing of emergency sample racks.

[0030] Specifically, the sample injection buffer module 30 includes a pallet 31 connected between two parallel sample rack conveyor belts 11, a sample rack pusher 32 for pushing the sample rack on the pallet 31, a sample injection pusher 33 for pushing the sample rack from the sample rack conveyor belt 11 of the transport track 10 to the pallet 31, and a retracting pusher 35 arranged at one end of the pallet 31 facing the detection track 20.

[0031] Please refer to Figure 1 The support plate 31 is used to support the sample rack, which is flush with the upper surface of the sample rack conveyor belt 11 to facilitate the transportation of the sample rack; the guard plate 12 on the side of the sample rack conveyor belt 11 is provided with a notch corresponding to the support plate 31.

[0032] Please refer to Figure 2 The sample rack pusher 32 includes a sample rack pusher base 321 disposed at the bottom of the support plate 31, a slide rail 322 disposed on the sample rack pusher base 321, a U-shaped bracket 323 slidably connected to the slide rail 322, and a drive device 324 for sliding the U-shaped bracket 323. The slide rail 322 extends perpendicular to the sample rack conveyor belt 11. The drive device 324 can adopt a synchronous belt transmission structure. After the U-shaped bracket 323 is connected to the synchronous belt, the movement of the synchronous belt drives the U-shaped bracket 323 to slide linearly. In other embodiments, the drive device 324 can also adopt a linear module.

[0033] Each end of the U-shaped bracket 323 is provided with a push handle 325. The middle portion of each push handle 325 is rotatably connected to the U-shaped bracket 323. One end of each push handle 325 protrudes from the support plate 31. The support plate 31 is provided with a linear through-slot corresponding to the push handle 325, allowing one end of the push handle 325 to extend above the support plate 31 and contact the sample rack. The other end of each push handle 325 extends toward the sample rack push handle base 321. The U-shaped bracket 323 is provided with a stopper 326 to limit the rotation range of the push handle 325. When push handle 325, driven by drive mechanism 324, pushes the sample rack forward, the sample rack exerts a counter-force on push handle 325, causing it to rotate clockwise. However, stopper 326 prevents this clockwise rotation, allowing push handle 325 to complete its push of the sample rack. When push handle 325 returns to its original position, it encounters another sample rack and, under the force, rotates counterclockwise, passing through the bottom of the other sample rack to the other side. Then, under the action of its own gravity, it returns to its original position, flipping over onto the support plate 31, allowing it to continue pushing the other sample rack forward. Furthermore, a bolt hole 327 is provided at the other end of push handle 325, to which a counterweight is connected to strengthen the gravity at the other end of push handle 325.

[0034] In another embodiment, please refer to Figure 3 The sample rack pusher 32 includes a sample rack pusher base 321 arranged at the bottom of the support plate 31, a slide rail 322 arranged on the sample rack pusher base 321, a U-shaped bracket 323 slidably connected to the slide rail 322, and a driving device 324 for pushing the U-shaped bracket 323 to slide. The extension direction of the slide rail 322 is perpendicular to the sample rack conveyor belt 11. The driving device 324 can adopt a synchronous belt transmission mechanism or a linear module connected to the U-shaped bracket 323. Pushers 325 are provided at both ends of the U-shaped bracket 323. The middle part of the pusher 325 is rotatably connected to the U-shaped bracket 323. One end of the pusher 325 extends upward from the side of the support plate 31 and bends to the top of the support plate 31. A tension spring 328 is provided between the other end of the pusher 325 and the U-shaped bracket 323, and the U-shaped bracket 323 is provided with a stopper 326. The principle of pushing the sample rack is the same as Figure 2 The embodiment shown is similar, but the reset is accomplished by the elastic force of spring 58 rather than its own weight.

[0035] Please refer to Figure 4 or Figure 5The sample introduction pusher includes a pusher base 331 disposed at the bottom of the sample rack conveyor belt 11 of the transport track 10, a guide rail 332 disposed on the pusher base 331, a pusher bracket 333 slidably connected to the guide rail 332, and a drive device 334 for pushing the pusher bracket 333 to slide. The guide rail 332 extends perpendicularly to the sample rack conveyor belt 11. The drive device 334 can be a synchronous belt transmission mechanism or a linear module connected to the pusher bracket 333. The pusher bracket 333 is provided with a push plate 335 extending above the sample rack conveyor belt 11, and the guard plate 12 is provided with a notch corresponding to the push plate 335. Driven by the drive device 334, the push plate 335 performs linear reciprocating motion, pushing the sample rack on the sample rack conveyor belt 11 onto the support plate 31. Furthermore, the push plate 335 is provided with a plurality of pads 336, which can concentrate the force of the push plate 335 on the sample rack from the entire plane to a plurality of small points, which can more effectively prevent the sample rack from tipping over during movement, thereby improving the reliability and transportation efficiency of the instrument.

[0036] The end of the support plate 31 of the sample injection buffer module 30 facing the detection track 20 is also provided with a retraction pusher 35 to prevent the sample rack that should be left on the support plate 31 from invading the detection track 20 and interfering with the transportation of other sample racks. Figure 6 The retraction pusher 35 includes a retraction bracket 351 disposed at the bottom of the support plate 31, a retraction shaft 352 rotatably connected to the retraction bracket 351, a retraction hook 353 disposed on the retraction shaft 352, and an electric push rod 354 disposed on the retraction bracket 351. The retraction hook 353 is provided with a driving arm 355 corresponding to the electric push rod 354. The retraction hook 353 is provided with a protrusion 356 extending toward the support plate 31, and the support plate 31 is provided with a through slot corresponding to the protrusion 356. After the electric push rod 354 extends, it contacts the driving arm 355, thereby driving the retraction hook 353 to rotate, extending the protrusion 356 out of the through slot, and pushing the sample rack away from the detection track 20. The driving arm 355 also acts as a counterweight. After the electric push rod 354 retracts, the protrusion 356 returns to its original position under the action of gravity and returns to the bottom of the support plate 31.

[0037] The structure of the first track change module can refer to the sample injection buffer module, including a pallet 31 connected between two parallel sample rack conveyor belts 11, a sample rack pusher 32 for pushing the sample rack on the pallet 31, a sample injection pusher 33 for pushing the sample rack from the sample rack conveyor belt 11 of the transport track 10 to the pallet 31, and a retracting pusher 35 arranged at one end of the pallet 31 facing the detection track 20.

[0038] The sample discharge buffer module 40 includes a support plate 31 connected between two parallel sample rack conveyor belts 11, a sample rack pusher 32 for moving the sample rack on the support plate 31, a sample discharge pusher 34 for pushing the sample rack from the sample rack conveyor belt 11 on the detection track 20 to the support plate 31, and a retraction pusher 35 provided at the end of the support plate 31 facing the transport track 10. The sample rack pusher 32 can be referred to as the sample rack pusher of the sample injection buffer module 30, and the two push in opposite directions. The sample discharge pusher 34 can be referred to as the sample injection pusher 33 of the sample injection buffer module 30, but the sample discharge pusher 34 is provided near the detection track 20. The retraction pusher 35 can be referred to as the retraction pusher of the sample injection buffer module 30.

[0039] The structure of the second track changing module can refer to the sample output buffer module 40. The structures of the first and second track changing modules can also refer to the existing sample rack conveying mechanism capable of completing bidirectional conveying.

[0040] The above is a description of one or more embodiments of the present invention, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
