Description

Technical Field

[0001] This utility model relates to the field of D-dimer, and more particularly to a D-dimer assay kit. Background Technology

[0002] An existing patent (publication number: CN206624210U) discloses a reagent kit including a box body with matrix-arranged cavities inside. Two opposing support legs are located at the bottom of the box body, each with a guide groove. A cooling box is positioned between the two support legs, each containing a cavity filled with ice. A slider that mates with the guide groove is mounted on the cooling box, which is slidably connected to the guide groove. The guide groove is located on the end face of the support leg that contacts the box body. When the slider is within the guide groove, the end face of the cooling box contacts the bottom surface of the box body. The end face of the cooling box is coated with sealing grease. An elastic rubber strip is fixedly mounted at the bottom of the guide groove. However, this reagent kit is inconvenient for D-dimer assays because the multiple reagent tubes inside the box are difficult to remove individually for testing. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a D-dimer assay kit that allows multiple reagent tube holders to move when the motor is running, ensuring that reagent tubes at different positions all pass through the test tube outlet. The kit also allows for easy removal of the reagent tube corresponding to the test tube outlet by opening the cover.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A D-dimer assay kit includes a kit body, a kit cap, a cover plate, reagent tube holders, a side toothed plate, a support trunk, an annular support rod, a sliding toothed plate, a rectangular slide rod, an eccentric rotating shaft, and a motor. The kit body is connected to the upper part of the kit cap, which is connected to the cover plate via a hinge. The kit cap has a test tube outlet, and the cover plate is positioned above the test tube outlet. An annular track connects to the kit body and has an annular groove. A slider is connected to the lower part of the reagent tube holders, and the slider is adapted to the annular groove. The slider is inserted into the annular groove and slides and rotates within the annular groove. Multiple reagent tube holders are distributed on the annular track. The upper part of the reagent tube holders is connected to the support trunk, and the upper part of the support trunk is connected to the annular support rod. The support trunk is symmetrically arranged on both sides of the annular support rod.

[0006] The reagent tube holder has an inner holding groove. The reagent tube passes through the annular support rod and is inserted into the inner holding groove. One end of the reagent tube holder has a No. 1 side plate, and the other end of the reagent tube holder has a No. 2 side plate. The lower surface of the No. 1 side plate is in contact with the No. 2 side plate. The No. 1 side plate is connected to the No. 2 side plate through a rotating shaft. The side of the reagent tube holder is connected to a side toothed plate.

[0007] The reagent kit has a clearance groove and a motor mounting plate inside the reagent kit. The motor is connected to the motor mounting plate by bolts. The motor shaft passes through the motor mounting plate and is connected to the eccentric shaft. The side of the sliding toothed plate has a toothed plate protrusion. The side of the eccentric shaft fits into the sliding toothed plate and the side of the eccentric shaft fits into the toothed plate protrusion. Beneficial effects

[0008] 1. The reagent kit cover of this utility model protects the test tubes inside the kit body. The annular track is installed and fixed inside the kit body. The reagent tube holder is connected to the annular support rod through the support trunk. The annular support rod and the inner holding groove cooperate to support the reagent tubes, so that the reagent tubes are placed in the reagent tube holder and kept vertical, preventing shaking during the transportation of D-dimer determination reagents. The second side plate is connected to the first side plate through the rotating shaft, so that the two adjacent reagent tube holders are connected by the shaft and can rotate around the rotating shaft. The slider is inserted into the annular groove, so that the reagent tube holder is placed on the annular track. The slider slides in the annular groove, so that a movable chain seat composed of multiple reagent tube holders connected end to end can move along the trajectory of the annular track.

[0009] 2. In this invention, a spring is fitted onto a rectangular slide rod. The spring, supported by the side plate of the slide rod, applies a pushing force to a circular pad, thereby pushing the sliding toothed plate to move. This causes the sliding toothed plate to disconnect from the side toothed plate. When the motor is running, it drives the eccentric shaft to rotate, causing the motor to push the sliding toothed plate to move. This causes the sliding toothed plate to move the side toothed plate, allowing multiple reagent tube holders to slide along a circular track inside the reagent kit. Under normal conditions, the eccentric shaft is disconnected from the sliding toothed plate, and the spring causes the sliding toothed plate to disconnect from the side toothed plate. This device allows multiple reagent tube holders to move when the motor is running, ensuring that reagent tubes at different positions pass through the test tube outlet. The cover can be opened to remove the reagent tube corresponding to the test tube outlet, making the operation convenient. Attached Figure Description

A slider 28 is connected to the lower part of the reagent tube holder 09. Block 28 is adapted to the annular groove 08. The slider 28 is inserted into the annular groove 08, so that the reagent tube holder 09 is placed on the annular track 07. The slider 28 slides in the annular groove 08 and rotates in the annular groove 08, so that a movable chain seat composed of multiple reagent tube holders 09 connected end to end can move along the trajectory of the annular track 07. Multiple reagent tube holders 09 are distributed on the annular track 07. The upper part of the reagent tube holder 09 is connected to the support trunk 14. The upper part of the support trunk 14 is connected to the annular support rod 15. The support trunk 14 is symmetrically arranged on both sides of the annular support rod 15. The annular support rod 15 and the inner holding groove 10 cooperate to support the reagent tube 16, so that the reagent tube 16 is placed in the reagent tube holder 09 and kept vertical, preventing shaking during the transportation of D-dimer determination reagents.

[0020] Example 2:

[0021] The reagent tube holder 09 of this utility model has an inner holding groove 10. The reagent tube 16 passes through the annular support rod 15 and is inserted into the inner holding groove 10. One end of the reagent tube holder 09 has a first side plate 11 and the other end has a second side plate 12. The lower surface of the first side plate 11 is in contact with the second side plate 12. The first side plate 11 is connected to the second side plate 12 through a rotating shaft 27, so that the two adjacent reagent tube holders 09 are axially connected and can rotate about the rotating shaft 27. The side of the reagent tube holder 09 is connected to a side toothed plate 13.

[0022] Example 3:

[0023] The reagent kit body 01 of this utility model has a relief groove 05. Inside the reagent kit body 01, there is a motor mounting plate 06. The motor 26 is connected to the motor mounting plate 06 by bolts. The motor 26 is mounted and fixed on the motor mounting plate 06. The rotating shaft of the motor 26 passes through the motor mounting plate 06 and connects to the eccentric rotating shaft 25. When the motor 26 works, it drives the eccentric rotating shaft 25 to rotate. The eccentric rotating shaft 25 rotates eccentrically. The side of the sliding toothed plate 17 has a toothed plate protrusion 18. The side of the eccentric rotating shaft 25 is in contact with the sliding toothed plate 17, and the side of the eccentric rotating shaft 25 is in contact with the toothed plate protrusion 18.

[0024] Example 4:

[0025] The sliding toothed plate 17 of this invention has a toothed side plate 19 on its side, and the toothed side plate 19 has a strip-shaped sliding hole 20. A rectangular slide rod 21 is adapted to the strip-shaped sliding hole 20 and is inserted into the strip-shaped sliding hole 20. The rectangular slide rod 21 slides within the strip-shaped sliding hole 20. The side of the rectangular slide rod 21 is connected to the reagent kit 01. The rectangular slide rod 21 passes through the strip-shaped sliding hole 20 and is connected to the reagent kit 01. A set of rectangular slide rods 21 provides guidance and support for the sliding toothed plate 17, ensuring the height of the sliding toothed plate 17 within the reagent kit 01. The rectangular slide rod 21 passes through a circular pad 22 and slides within the circular pad 22. The side of the circular pad 22 is in contact with the toothed side plate 19. The side of the rectangular slide rod 21 has a slide rod side plate 24. A spring 23 is sleeved on the rectangular slide rod 21. One end of the spring 23 abuts against the slide rod side plate 24, and the other end of the spring 23 abuts against the circular pad 22. The sliding toothed plate 17 and... The side toothed plate 13 is engaged, and the spring 23 is sleeved on the rectangular slide rod 21. The spring 23 applies a pushing force to the circular pad 22 with the slide rod side plate 24 as support, thereby pushing the sliding toothed plate 17 to move, so that the sliding toothed plate 17 is disconnected from the side toothed plate 13. When the motor 26 works, it drives the eccentric rotating shaft 25 to rotate, so that the motor 26 pushes the sliding toothed plate 17 to move, so that the sliding toothed plate 17 drives the side toothed plate 13 to move, thereby causing multiple reagent tube holders 09 to slide along the annular track 07 inside the reagent kit body 01. Under normal conditions, the eccentric rotating shaft 25 is disconnected from the sliding toothed plate 17. Under the action of the spring 23, the sliding toothed plate 17 is disconnected from the side toothed plate 13. This device causes the motor 26 to drive multiple reagent tube holders 09 to move when it works, so that the reagent tubes 16 at different positions all pass through the test tube outlet 03. The cover plate 04 can be opened to take out the reagent tubes 16 corresponding to the test tube outlet 03, which is convenient to operate.
