Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a reagent kit. In addition, the present invention also relates to a reagent kit storage tray, and a medical analyzer comprising the reagent kit and the reagent kit storage tray. Background Art

[0002] At present, some in vitro diagnostic projects require the use of solid-phase reagents, and such solid-phase reagents need to be mixed evenly before they can be used. This requires that the reagent bottle must be in a constant state of motion when the reagent kit is used in a medical analyzer. Therefore, the reagent bottle and the reagent kit rack must not only be matched properly, but also not affect the rotation of the reagent bottle; and the existing reagent bottle assembly design and installation method is single, and the driving and positioning methods on different instruments are also different, resulting in the reagent kit cannot be universal. In addition, when the reagent kit on the market is rotated and mixed, the friction surface of the reagent bottle rotating surface contacts more, and it is easy to drop powder. The powder will accumulate between the reagent bottle body and the reagent bottle rack, affecting the rotation of the reagent bottle, causing instrument-related drive system failure, and then causing the mixing function to fail; the puncture sealing sheet is too thick, causing the reagent needle to puncture and obtain the reagent. The reaction force of the sealing sheet on the reagent needle is too large, and the diaphragm reset elastic force is too large, causing the reagent needle and the sealing diaphragm to vibrate, resulting in serious splashing; the flat sealing sheet is not easy to recover, causing the reagent to volatilize, the concentration of the magnetic beads changes, and affecting the reagent experiment results. During transportation, the test kit tipped over and the vibration caused the magnetic beads to enter between the puncture cap and the sealing cap, causing the concentration of the magnetic beads to change and affecting the reagent test results.

[0003] Therefore, how to improve the applicability of the kit is a technical problem that those skilled in the art currently need to solve. Summary of the invention

[0028] In this embodiment, the reagent kit 2 includes a reagent kit rack 2-3, and the side of the reagent kit rack 2-3 has at least one contoured positioning portion 2-1 extending in the longitudinal direction, and the contoured positioning portion 2-1 is similar in structure to the side wall of the rib 3-1 of the reagent kit storage tray 3, that is, after the reagent kit rack 2-3 and the rib 3-1 of the reagent kit storage tray 3 correspond in radial position, the reagent kit rack 2-3 can be inserted in the longitudinal direction between the two ribs 3-1 of the reagent kit storage tray 3. Preferably, for easy assembly and stable installation, the two sides of the reagent kit rack 2-3 are provided with contoured positioning portions 2-1, and preferably have the same structure.

[0029] Furthermore, after the contoured positioning portion 2 - 1 is assembled with the rib 3 - 1 along the longitudinal direction, the contoured positioning portion 2 - 1 and the rib 3 - 1 can be engaged with each other along the radial direction of the reagent kit storage tray 3 .

[0030] The reagent kit 2 provided by the present invention utilizes the contour structure design between the reagent kit rack 2-3 and the retaining edge 3-1 of the reagent kit storage tray 3. When assembling the reagent kit rack 2-3, the positional relationship between the contour structures can be utilized to achieve rapid positioning, accurate positioning, and stable installation.

[0031] Specifically, the reagent box rack 2-3 is preferably an integrated structure, and the reagent box rack 2-3 is provided with a plurality of reagent compartments and at least one bottle holder, and the plurality of reagent compartments can realize the independent coexistence of multiple reagents for use by the instrument. Specifically, the partition between two adjacent reagent compartments can be eliminated, and a reagent compartment with a larger size exists, which can be achieved by adjusting the structure of the mold when processing the reagent box rack 2-3. Since the external structure of the reagent box rack 2-3 does not change, it does not affect the use in the instrument.

[0032] Furthermore, the profiling positioning portion 2-1 is a profiling positioning groove, and correspondingly, a positioning boss should be provided on the rib 3-1 of the reagent box storage tray 3. The above-mentioned setting, by using the setting of the profiling positioning groove, can make the reagent box rack 2-3 and the reagent box storage tray 3 convenient and fast to position, and realize the clamping connection between the two in the radial direction of the reagent box storage tray 3, that is, the profiling positioning portion 2-1 can not only meet the requirements of fast positioning, but also realize the limit in the radial direction of the reagent box storage tray 3. Of course, the profiling positioning portion 2-1 can also be a profiling positioning boss, and correspondingly, a positioning groove should be provided on the rib 3-1 of the reagent box storage tray 3. Preferably, in order to improve the convenience of assembly, the profiling positioning groove is preferably arc-shaped along the radial direction of the reagent box storage tray 3.

[0033] On the basis of the above-mentioned embodiments, the side of the reagent box rack 2-3 is also provided with a side clamping portion 2-2 which can be clamped with the retaining edge 3-1 of the reagent box storage tray 3 in the longitudinal direction.

The elastic side clamping portion is easy to use, and is provided with an introduction slope. When the reagent reagent rack 2-3 is inserted into the reagent reagent storage tray 3, the introduction slope on the elastic side clamping portion first contacts the side clamping platform 3-1-2 on the retaining edge 3-1 of the reagent reagent storage tray 3. As the reagent reagent rack 2-3 moves downward, the elastic side clamping portion moves toward the inner side of the reagent reagent rack 2-3 until the elastic side clamping portion is clamped with the side clamping platform 3-1-2. When the reagent reagent rack 2-3 needs to be removed, it can be pulled out with force in the reverse direction, which is easy to operate and reliable in positioning.

Specifically, the side of the reagent kit rack 2-3 is designed to imitate the "mountain"-shaped structure, and after being installed on the reagent kit storage tray 3, multiple position positioning and limiting can be achieved, and the positioning is accurate and the installation is stable. Of course, the above-mentioned mountain-shaped structure is a preferred solution, and it can also be replaced by other structures, which can be assembled in the longitudinal direction and the radial clamping structure are all possible.

Specifically, the movable block 4 is connected to the reagent box rack 2-3 through a slideway and a slider, and the movable block 4 can slide horizontally and / or vertically relative to the reagent box rack 2-3. Preferably, the movable block 4 is provided with a barcode identification portion and / or a radio frequency identification portion.

[0041] The above arrangement utilizes the side positioning edge 3-1-1 to realize rapid positioning of the reagent kit rack 2-3, and through the clamping connection between the contoured positioning portion 2-1 and the side positioning edge 3-1-1, the two are limited in the radial direction of the storage tray body, thereby improving assembly efficiency, accurate positioning, and stable installation.

[0042] Preferably, the retaining edge 3-1 is provided with a mountain-shaped structure, which can cooperate with the mountain-shaped structure of the side of the reagent kit rack 2-3.
