Technical Field
[0001] This utility model relates to the field of in vitro diagnostic instrument technology, specifically to a reagent compartment for in vitro diagnostic instruments with a low-viscosity coating protective structure. Background Technology
[0002] In vitro diagnostic instruments are instruments that test human samples, such as blood, outside the human body to obtain clinical diagnostic information. They are commonly used in fields such as physical examinations, critical illness monitoring, and disease management. In vitro diagnostic instruments include clinical chemistry analyzers, immunochemistry analyzers, blood analyzers, and microbiology analyzers. In vitro diagnostic instruments are usually composed of reagent compartments, optical modules, liquid circuits, and gas circuit systems. The reagent compartments of in vitro diagnostic instruments are equipped with refrigeration equipment to maintain the internal temperature of the reagent compartment and facilitate reagent storage. There are various types of reagent compartments for in vitro diagnostic instruments on the market.
[0003] For example, patent application CN211478335U discloses an in vitro diagnostic instrument and a waterproof sleeve. The in vitro diagnostic instrument includes a reagent compartment, an identification mechanism, and a waterproof sleeve. The reagent compartment includes a circumferentially arranged wall defining a space for placing reagents, and has a mounting hole penetrating the wall. The identification mechanism identifies the reagents within the reagent compartment. The waterproof sleeve is fitted around the identification mechanism and installed together with the identification mechanism within the mounting hole. Through this method, the present application can reduce the amount of condensate generated on the wall of the reagent compartment flowing to the identification mechanism, thus protecting the identification mechanism.
[0004] For example, the utility model with authorization announcement number CN205506850U provides a reagent compartment for in vitro diagnostic equipment, including a reagent storage device and a reagent mixing and conveying device. An insulation layer is provided around the reagent storage device, which is mounted on the reagent mixing and conveying device. The reagent mixing and conveying device includes a transfer device and a driving device, and the transfer device includes a conveying mechanism and a mixing mechanism. The reagent compartment has a large reagent storage capacity and can accurately deliver reagents to the reagent collection position of the analyzer. Furthermore, it can effectively mix the reagents while transferring them.

Therefore, we propose an in vitro diagnostic instrument reagent compartment with a low-viscosity coating protective structure to solve the problems mentioned above. Utility Model Content

Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-7 The present invention provides a technical solution: an in vitro diagnostic instrument reagent compartment with a low-viscosity coating protective structure, comprising a first base 1, a reagent storage refrigerator 2, an insulation cover 3, a dual-axis motor 4, an adjusting wheel 5, a second base 6, a drive motor 7, an adjusting block 8, a connecting plate 9, a reagent tray 10, a limiting and fixing ring 11, a sliding groove 12, an electric sliding rail 13, a sample loading gun 14, and a low-viscosity coating protective structure body 15;
[0032] First, as attached Figure 1 As shown, the first base 1 is installed on the in vitro diagnostic instrument. A reagent storage refrigerator 2 is installed on the upper right side of the first base 1. The reagent kit is placed in the reagent storage refrigerator 2. An electric slide rail 13 is installed on the upper left rear of the first base 1. A sample loading gun 14 is installed on the electric slide rail 13. The position of the sample loading gun 14 is adjusted. An adjustment mechanism to prevent cold air loss is provided on the top of the reagent storage refrigerator 2. The position of the heat preservation cover 3 is adjusted so that the sample loading gun 14 can be inserted into the reagent storage refrigerator 2. The sample loading gun 14 loads the reagent. An intermittent rotation drive mechanism is provided inside the reagent storage refrigerator 2 to drive the reagent tray 10 to rotate intermittently and move the reagent intermittently, which facilitates accurate sample loading and improves work efficiency. The sample loading gun 14 is provided with a low-viscosity coating protective structure body 15. When loading the sample, it can prevent the sample from adhering to the sample loading gun 14, prevent cross-contamination of samples, and ensure the test results.
[0033] As attached Figure 2 and attached Figure 3As shown, the adjustment mechanism includes an insulated cover plate 3, a dual-axis motor 4, and adjusting wheels 5. The dual-axis motor 4 is installed inside the reagent storage refrigerator 2. When the dual-axis motor 4 is turned on, adjusting wheels 5 are installed on both the front and rear sides of the dual-axis motor 4. The dual-axis motor 4 drives the adjusting wheels 5 to rotate. The insulated cover plate 3 and the adjusting wheels 5 are meshed and connected. The adjusting wheels 5 drive the insulated cover plate 3 to move. The insulated cover plate 3 is connected to the reagent storage refrigerator 2 in a slot. The reagent storage refrigerator 2 plays a limiting role for the insulated cover plate 3, allowing the insulated cover plate 3 to slide on the reagent storage refrigerator 2. Adjusting the position of the insulated cover plate 3 exposes the reagent tray 10 and reagent kit inside the reagent storage refrigerator 2. The insulated cover plate 3 covers the reagent storage refrigerator 2 to prevent the cold air inside the reagent storage refrigerator 2 from escaping during sample loading, ensuring that the reagent is stored within a suitable temperature range, stabilizing the ambient temperature of the reagent, reducing changes in the chemical properties of the reagent, and ensuring the accuracy of the test results.
[0034] As attached Figure 2 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 As shown, a second base 6 is installed at the bottom of the interior of the reagent storage refrigerator 2. A reagent tray 10 is tightly attached to the top of the second base 6. The driving mechanism includes a drive motor 7, an adjusting block 8, and a connecting plate 9. The drive motor 7 is installed inside the second base 6. When the drive motor 7 is turned on, the adjusting block 8 is installed at the output end of the drive motor 7. The drive motor 7 drives the adjusting block 8 to rotate. The outer slot of the adjusting block 8 is connected to the connecting plate 9. The adjusting block 8 drives the connecting plate 9 to rotate. The reagent tray 10 is fixed on the top of the connecting plate 9. The connecting plate 9 drives the reagent tray 10 to rotate, thereby adjusting the position of the reagent kit installed on the reagent tray 10. Since the lower inner cross-section of the connecting plate 9 has a concave-convex structure, the convex corner and the rounded edge on the adjusting block 8 can be connected to the slot of the connecting plate 9 respectively. When the convex corner is connected to the slot of the connecting plate 9, it can push the connecting plate 9 to rotate. When the rounded edge is connected to the slot of the connecting plate 9, it can limit the movement of the connecting plate 9 and prevent the connecting plate 9 from moving. This allows the connecting plate 9 and the reagent tray 10 to rotate intermittently, achieving accurate sample loading.
[0035] As attached Figure 4 and attached Figure 5 As shown, a sliding groove 12 is provided on the upper part of the second base 6, and a limiting ring 11 is integrally provided on the lower outer side of the reagent tray 10. The limiting ring 11 is connected to the second base 6 in a slot. When the reagent tray 10 rotates, the limiting ring 11 slides in the second base 6 to limit the reagent tray 10 and ensure the stability of the reagent tray 10 when it rotates.
