Description

Technical Field

[0001] The present application belongs to the technical field of in vitro diagnostic equipment, and specifically relates to a tube cap recovery device and a sample pre-processing system. Background Art

[0002] In order to improve the automation level of the in vitro diagnostic pipeline system, a sample pretreatment system is set at the front end of the pipeline, which can centrifuge and open the lid of the sample tubes on the test tube rack.

[0003] The uncapping operation is the process of removing and discarding the cap of the sample tube. In the prior art, a trash can for holding tube caps is placed at the bottom of the equipment. The number of tube caps dropped into the trash can is used to estimate whether the trash can is full. For example, if the full load number is set to 200, when the tube cap count reaches 200, the system will remind the staff that the trash can is full, and then the staff will clean it up.

[0004] However, simply relying on counting pipe caps to estimate whether the trash can is full can easily lead to the failure to identify the pipe caps when they are already full, resulting in the continued production of pipe caps scattered inside the equipment, affecting the operation of the equipment. On the other hand, the pipe caps fall into the trash can at a fast speed, and the sensor needs to be able to quickly capture the information of the falling pipe caps in a timely manner. If the sensor recognition is unstable, there may be missed detections, which will lead to inaccurate recognition of the full load status. Utility Model Content

DETAILED DESCRIPTION

[0029] The following is a clear and complete description of the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] Reference Figure 1 As shown in the structural schematic diagram, an embodiment of the present application provides a pipe cap recovery device, including: a frame 1; a weighing component 2, fixed on the frame 1; a recovery box 3, fixed on the surface of the weighing component 2, and the weighing component 2 is used to identify the recovery box 3 and the weight of the pipe caps contained in the recovery box 3.

[0031] Sample pre-processing systems typically include a controller for receiving and processing information. In this embodiment, the weighing assembly 2 feeds the identified weight information back to the controller, which then determines whether the bin is fully loaded based on whether the weight information reaches a preset threshold. Specifically, if the weight information does not reach the preset threshold, the bin is determined to be partially loaded; if the weight information is greater than or equal to the preset threshold, the bin is determined to be fully loaded.

[0032] It can be seen from the above technical solution that in this embodiment, a weighing component is used for weight identification, and the tube caps removed during the opening operation all fall into the recycling box 3, so that each tube cap can be weighed. Compared with the existing technology, the solution of using a weighing component to determine whether it is fully loaded is more stable and reliable, reduces the tediousness of manual identification, and improves the efficiency and convenience of instrument use.

[0033] Reference Figure 2 As shown in the structural schematic diagram, the frame 1 includes: a base plate 11; a slide rail 12, which is arranged on the base plate 11; a movable plate 13, which is slidably connected to the slide rail 12 and is used to slide on the slide rail 12; a connecting plate 14, which is mounted on two parallel movable plates 13 and moves with the movable plates 13, and the weighing assembly 2 is fixedly connected to the connecting plate 14.

[0034] In this embodiment, two slide rails 12, two movable plates 13 and two connecting plates 14 are provided. A rectangular area is formed between the two movable plates 13 and the two connecting plates 14. The area is used to place the recycling box 3. Therefore, the size of the area is slightly larger than the bottom area of ​​the recycling box 3.

[0035] The weighing assembly provided in this embodiment is arranged at the bottom of the rectangular area, and the weighing assembly 2 includes: a weighing sensor 21, which is fixedly connected to the connecting plate 14 and is used to identify the weight of the recycling box 3 and the pipe cap; a weighing circuit board 22, which is electrically connected to the weighing sensor 21 and is used to feedback weight information.

[0036] The load cell 21 is a cantilever beam sensor equipped with a strain gauge. Pressure from the recycling bin 3 and the pipe caps causes the strain gauge to deform. The greater the deformation, the greater the weight. This deformation is converted into an electrical signal, which is detected by the weighing circuit board 22 and fed back to the controller. Furthermore, since the weight of the recycling bin 3 is fixed, the weight of the recycling bin 3 is pre-determined. The weight of the recycling bin 3 is subtracted from the weight obtained by the load cell 21 to obtain the weight of the pipe caps in the recycling bin 3, i.e., the tare weight. The threshold data required for full load determination is adjusted accordingly based on whether or not the tare weight is used.

[0037] To maintain the stability of recycling bin 3, this embodiment includes two load cells 21. These load cells 21 are positioned diagonally opposite each other, allowing bin 3 to be suspended above the load cells 21, enabling accurate weighing of bin 3 and the pipe caps. In other embodiments, three or four load cells 21 may be provided; this embodiment utilizes two load cells to reduce costs. Each load cell 21 is capable of detecting a specific weight, and the average of these multiple weights represents the weight of bin 3 and the pipe caps.

[0038] Reference Figure 2 As shown in the structural diagram, the tube cap recovery device also includes a handle bracket assembly 4, which is used to slide the movable plate 13 and the recovery box 3 under the action of an external force. In this embodiment, the recovery box 3 is fixedly connected to the movable plate 13 via the weighing assembly 2. The handle bracket assembly 4 is fixedly connected to the movable plate 13. The handle bracket assembly 4 is located near the outside of the sample pretreatment system so that the operator can access the handle bracket assembly 4 and pull it outward, causing the recovery box 3 to slide outward at the same time. Here, "sliding outward" refers to sliding in a direction away from the entire device.

[0039] In this embodiment, the handle bracket assembly 4 includes a vertical panel 41 and a handle 42 disposed on the panel 41. The bottom end of the panel 41 is fixedly connected to the movable plate 13. To save effort, the handle 42 can be located on the end of the panel 41 away from the movable plate 13. The operator pulls the handle 42 to slide the recycling bin 3 outward, thereby cleaning the pipe caps inside the recycling bin 3.

[0040] Reference Figure 3 As shown in the structural diagram, a reset sensor 5 is provided on one side of the slide rail 12. The reset sensor 5 is used to provide feedback on whether the recycling box 3 is reset. The reset sensor 5 includes an optical coupler sensor 51 and a light shielding plate 52. The light shielding plate 52 can be fixed to one side of the recycling box 3 or provided on one side of the connecting plate 14. When reset, the light shielding plate 52 is located within the U-shaped position of the optical coupler sensor 51.

[0041] The following briefly describes the overall process of the embodiment of the present application: when the weight of the pipe caps inside the recycling box 3 reaches a preset threshold, the controller reminds the operator to clean it; the operator pulls the handle 42 outward and slides the recycling box 3 outward. At this time, the light-shielding plate 52 disengages from the U-shaped position of the optical coupling sensor 51; after cleaning is completed, the operator pushes the handle 42 inward until the light-shielding plate 52 returns to the U-shaped position, and the optical coupling sensor 51 is blocked, which is reset at this time.

[0042] To prevent the operator from leaving the cap unreset for a long time after cleaning the tube, causing abnormalities in the sample pretreatment system, an alarm device can be provided in this embodiment. For example, a timer can be set starting from the moment the light shield 52 leaves the U-shaped position. If the controller does not receive the reset signal after a 2-minute interval, the alarm device will sound an alarm. The alarm device can be an acoustic or optical sensor, etc. By adding an automatic alarm device, this device can further eliminate human error and improve weighing stability.

[0043] In order to prevent the recycling box 3 from impacting the reset sensor 5 when being pushed inward, this embodiment is further equipped with a limit block 6. When the recycling box 3 is reset, the limit block 6 abuts against the connecting plate 14 to prevent the recycling box 3 from continuing to slide inward.

[0044] The present invention also provides a sample pre-processing system, comprising: Figure 1 The tube cap recovery device provided by any implementation method. The sample pretreatment system provided in this embodiment has all the technical effects of the above-mentioned tube cap recovery device, which will not be described in detail here.

[0045] The above are merely embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application are included in the scope of the claims of the present application to be approved.
