Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a sample buffer device and a sample testing and analysis pipeline system. Background Technology

[0002] A sample buffering device is installed between the analytical instrument and the sample supply and recovery unit for buffering and scheduling samples. The sample buffering device uses a scheduling trolley to schedule sample racks (each rack can hold multiple reaction cups for loading samples). The sample supply and recovery unit and the scheduling trolley are directly connected. However, existing analytical instruments require connection to sample supply and recovery units from different brands, making it difficult for the scheduling trolley to be connected according to actual needs. This makes it difficult to arrange the sample buffering device according to actual requirements and adapt it to different working environments. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a sample caching device that solves the problems of sample caching devices being difficult to lay out according to actual needs and adapting to different working environments.

[0035] Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0037] This utility model embodiment provides a sample caching device.

[0038] like Figures 1 to 6 The sample buffer device includes a recovery track assembly 210, a sample introduction track assembly 220, a regular sample buffer space 500, an emergency sample space 600, and a dispatch trolley 100.

[0039] The dispatching trolley 100 can move in the forward and backward direction so that it can dock with one of the recovery track assembly 210, the sample introduction track assembly 220, the conventional sample buffer position 500, and the emergency sample position 600 in the left and right direction, and can mutually retrieve and store the sample rack 800 during docking.

[0040] The support bottoms of the recovery track assembly 210 and the sample infeed track assembly 220, which support the sample rack 800, can move left and right.

[0041] Based on this structural design, firstly, a recovery track assembly 210 and a sample infeed track assembly 220 are set between the scheduling trolley 100 and the sample supply and recovery device. This reduces the required length of the sample supply and recovery device and facilitates pairing between the sample supply and recovery device and the sample buffer device. Secondly, the supporting bottoms of the recovery track assembly 210 and the sample infeed track assembly 220, which support the sample rack 800, can move left and right.

[0042] Based on this structural design, a recovery track assembly 210 and a sample loading track assembly 220 were added, allowing the sample buffer device to be laid out according to actual needs and adapt to different working environments, thereby improving the efficiency and flexibility of sample buffering. The docking of the scheduling trolley 100 with each component enables the sample rack 800 to be quickly moved between different locations, improving sample scheduling speed. Simultaneously, the overall layout of the sample buffer device can be adjusted according to actual working requirements, enhancing the adaptability and practicality of the device.

[0043] In addition, the recovery track assembly 210 and the sample introduction track assembly 220 can drive the sample holder 800 to move, ensuring the continuity of the sample holder 800's movement.

[0044] It should be noted that in other embodiments, there may be two sample introduction track components 220, one for regular sample introduction and the other for emergency sample introduction; the number of regular sample buffer positions 500 and emergency sample positions 600 will be adjusted according to the actual situation. Usually, the number of regular sample buffer positions 500 will be more than the number of emergency sample positions 600, and their occupied areas are correspondingly related, as shown in the figure.

[0045] In this embodiment, the recovery track assembly 210 and / or the sample introduction track assembly 220 are docking structures 300;

[0046] The docking structure 300 includes:

[0047] The mating part 310 includes the base plate 311.

[0048] The drive structure 320 includes a drive wheel 321, a first driven wheel 322, a second driven wheel 323, a conveyor belt 324, and a drive motor 325. The rotation lines of the drive wheel 321, the first driven wheel 322, and the second driven wheel 323 are in the left-right direction. The first driven wheel 322 and the second driven wheel 323 are arranged at left and right intervals, respectively. The conveyor belt 324 is sleeved on the outside of the drive wheel 321, the first driven wheel 322, and the second driven wheel 323. The drive motor 325 is used to drive the drive wheel 321.

[0049] The section of the conveyor belt 324 located between the first driven wheel 322 and the second driven wheel 323 is the drive section. The drive section is located above the base plate 311 and is used to drive the sample rack 800 to move. It is located between the two side plates 312.

[0050] The application of the drive structure 320 enables the sample holder 800 to move automatically within the docking structure 300. This design also makes the transfer of the sample holder 800 more stable and reliable, improving safety and accuracy.

[0051] In this embodiment, the docking structure 300 further includes:

[0052] Two side plates 312 are respectively connected to the left and right sides of the base plate 311 and extend upward. The base plate 311 and the two side plates 312 together form the sample rack 800 channel.

[0053] This structural design allows the recovery track assembly 210 and the sample introduction track assembly 220 to better interface with the scheduling trolley 100, improving the efficiency of sample scheduling.

[0054] In this embodiment, the docking structure 300 further includes at least one docking detection optocoupler for detecting whether a sample holder 800 is placed on the docking component 310. This allows for timely detection of whether a sample holder 800 is placed on the docking component 310, facilitating timely adjustments to the working state.

[0055] like Figure 6 As shown, in this embodiment, the sample buffer device further includes a pusher assembly 700 for moving the sample rack 800 from the sample inlet track assembly 220 to the scheduling trolley 100. This effectively ensures that the sample rack 800 is moved from the sample inlet track assembly 220 to the scheduling trolley 100, preventing the sample rack 800 from being unable to be driven to the scheduling trolley 100 by the driving force of the sample inlet track assembly 220 itself.

[0056] Specifically, in this embodiment, the pusher assembly 700 includes a pusher base 710, a pusher block 720, an elastic element 730, and a drive mechanism 740. The drive mechanism 740 can drive the pusher base 710 to reciprocate between a starting position and an ending position. The pusher block 720 is rotatably connected to the pusher base 710, and the pusher block 720 has a push position and an avoidance position relative to the pusher base 710. Under the elastic force of the elastic element 730, the pusher block 720 rotates to the push position. During the process of the pusher base 710 resetting from the ending position to the starting position, when it is blocked by the sample rack 800, the pusher block 720 rotates to the avoidance position, thereby avoiding the sample rack 800. The design of the pusher block 720 also enables the pusher to automatically avoid the sample rack 800 when it encounters it, avoiding collisions and damage, and improving safety and reliability.

[0057] In this embodiment, the pusher assembly 700 further includes a connecting rod 750, which extends vertically and connects the push seat 710 and the drive mechanism 740.

[0058] The drive mechanism 740 is located below the recovery track assembly 210.

[0059] The reduced spacing between the recovery track assembly 210 and the sample introduction track assembly 220 results in a more compact structure. The placement of the drive structure 320 below the recovery track assembly 210 also enhances the overall aesthetics of the device, reduces space requirements, and provides greater convenience for practical applications.

[0060] In this embodiment, the pusher assembly 700 further includes a pusher baffle and at least two pusher slot optocouplers. The application of the pusher baffle and pusher slot optocouplers can monitor the position of the pusher block 720 in real time, providing accurate information for operation. At the same time, this automated detection method also reduces human error and improves work efficiency and reliability.

[0061] In this embodiment, the sample buffer device further includes an active track assembly 400;

[0062] The active track assembly 400 includes a channel structure 410 and a track-changing structure 420. The channel structure 410 is movable between a clearance position and a docking position. When the channel structure 410 is in the docking position, it docks with the recovery track assembly 210. The track-changing structure 420 enables the channel structure 410 to move between the clearance position and the docking position.

[0063] When the dispatching trolley 100 moves to dock with the recovery track assembly 210, the track-changing structure 420 causes the channel structure 410 to move to the clearance position so that the sample rack 800 of the recovery track assembly 210 can return to the dispatching trolley 100.

[0064] When the sample rack 800 needs to return directly from the testing and analysis instrument to the recovery track assembly 210, the track-changing structure 420 puts the channel structure 410 in the docking position, allowing the sample rack 800 to pass through. At this time, there is no need for the scheduling trolley 100, which can perform other operations.

[0065] The activity track assembly 400 also includes a connector 431 connected to the recycling track assembly 210, and the connector 431 is provided with a limiting plate 432.

[0066] When the elastic force of the track-changing structural component 420 drives the channel structure 410 to move to the avoidance position, it abuts against the limiting plate 432.

[0067] The spring, as a track-changing structural component 420, can quickly respond to the movement of the scheduling trolley 100, enabling the channel structure 410 to move to the avoidance or docking position in a timely manner, thus improving the sample scheduling speed. At the same time, the limiting plate 432 can prevent the channel structure 410 from moving excessively, ensuring the safety and stability of the device.

[0068] In this embodiment, the track-changing structure 420 is a spring, which undergoes compression deformation under force;

[0069] In this embodiment, the channel structure 410 is connected to the connector 431 via a slider rail structure.

[0070] The application of a slider-rail structure makes the movement of the channel structure 410 smoother, reducing jamming and shaking, and improving the transfer speed and safety of the sample rack 800. At the same time, this structure also makes the maintenance and replacement of the channel structure 410 easier, improving the maintainability of the device.

[0071] In this embodiment, the channel structure 410 is connected to a rubber pad 440. When the dispatching trolley 100 moves to dock with the recovery track assembly 210, the rubber pad 440 abuts against the channel structure 410. The application of the rubber pad 440 can reduce wear and collision during the docking process and extend the service life of the equipment. At the same time, the cushioning effect of the rubber pad 440 can also reduce the vibration of the sample rack 800 during the transfer process, improving the safety and stability of the sample.

[0072] In this embodiment, the movable track assembly 400 also includes a movable track baffle and a movable track slot type optocoupler. When the scheduling trolley 100 moves to dock with the recovery track assembly 210, the movable track baffle triggers the movable track slot type optocoupler.

[0073] The application of movable track baffles and movable track slot-type optocouplers allows for real-time monitoring of the docking status between the dispatching trolley 100 and the recovery track assembly 210, providing accurate information for operation. Simultaneously, this automated detection method reduces human error and improves work efficiency and reliability.

[0074] This invention also proposes a sample testing and analysis pipeline system, which includes a sample buffer device. The specific structure of the sample buffer device is as described in the above embodiments. Since this sample testing and analysis pipeline system adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0075] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
