[0002] Urine testing is a routine test item in modern medical engineering and clinical medicine, and is one of the three major routine tests. Urine protein analyzer is a special instrument for clinical urine analysis combined with reagents made using dry chemical principles.

[0026] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0027] like Figure 1-3 A reagent storage mechanism of a urine protein analyzer, the urine protein analyzer includes a machine and a controller, a reagent extraction mechanism is arranged on the machine, the reagent storage mechanism and the reagent extraction mechanism are electrically connected to the controller respectively, and the reagent extraction mechanism can extract the detection reagent from the reagent storage mechanism.

[0028] The reagent storage mechanism comprises a storage mounting frame 1, which is fixedly connected to the machine, and a reagent storage tray 2 is arranged on the storage mounting frame 1, and the reagent storage tray 2 is rotatably connected to the storage mounting frame 1, and a plurality of reagent holding slots 3 are arranged in the reagent storage tray 2, and the reagent holding slots 3 are used to place the detection reagent. A storage drive component is arranged on the storage mounting frame 1, and the output end of the storage drive component is connected to the reagent storage tray 2, and the storage drive component is used to drive each reagent holding slot 3 to be connected to the reagent extraction mechanism respectively. Before the detection, various detection reagents are placed in each reagent holding slot 3 respectively; during the detection, the storage drive component is controlled to work, and the reagent storage tray 2 is driven to rotate, so that each reagent holding slot 3 is connected to the reagent extraction mechanism. When the reagent holding slot 3 is connected to the reagent extraction mechanism, the reagent extraction mechanism is controlled to extract the detection reagent from the reagent holding slot 3. The reagent storage mechanism can place multiple detection reagents at the same time, and the storage drive component can be operated to enable the reagent extraction mechanism to extract different detection reagents respectively, without manual replacement, thereby improving the degree of automation and reducing the difficulty and labor intensity of the operation.

[0029] Specifically, the storage drive assembly includes a storage drive motor 4, which is connected to the storage mounting frame 1. The output end of the storage drive motor 4 is provided with a storage transmission assembly, which is connected to the reagent storage tray 2. During detection, the storage drive motor 4 is controlled to drive the storage transmission assembly to move, thereby driving the reagent storage tray 2 to rotate, and driving each reagent containing tank 3 to move, so that the reagent containing tanks 3 storing different detection reagents are respectively aligned with the reagent extraction mechanism, so that the reagent extraction mechanism extracts different detection reagents.

[0030] The storage drive assembly includes a storage drive wheel 5, a storage transmission belt 6 and a storage driven wheel 7. The reagent storage tray 2 is provided with a storage drive shaft 8, which is rotatably connected to the storage mounting frame 1. The storage driven wheel 7 is sleeved on the storage drive shaft 8. The storage drive wheel 5 is connected to the output end of the storage drive motor 4, and the storage transmission belt 6 is sleeved on the storage drive wheel 5 and the storage driven wheel 7. When working, the storage drive motor 4 works, drives the storage drive wheel 5 to rotate, drives the storage transmission belt 6 to move, and then pulls the storage driven wheel 7 to rotate; the rotation of the storage driven wheel 7 will drive the storage drive shaft 8 and the reagent storage tray 2 to rotate synchronously, thereby driving each reagent holding tank 3 to a position relative to the reagent extraction mechanism, so that the reagent extraction mechanism extracts different detection reagents from each reagent holding tank 3.

[0031] In order to accurately limit the movement stroke of the reagent storage tray 2, a sensing paddle 9 is sleeved on the storage drive shaft 8, and sensing convex teeth 10 are respectively provided at the corresponding positions of the sensing paddle 9 and the reagent holding tank 3. A storage sensor 11 is provided on the storage mounting frame 1, and the sensing convex teeth 10 can be connected with the storage sensor 11 respectively. When it is necessary to drive different reagent holding tanks 3 to align with the reagent extraction mechanism, the storage drive motor 4 is controlled to work, drive the storage drive shaft 8 and the reagent storage tray 2 to rotate, and drive the sensing paddle 9 to rotate at the same time. When the corresponding sensing convex teeth 10 are connected with the storage sensor 11, the feedback signal controls the storage drive motor 4 to stop working; at this time, the reagent storage tray 2 also drives the corresponding reagent holding tank 3 to the position relative to the reagent extraction mechanism, and then controls the reagent extraction mechanism to extract the detection reagent from the reagent holding tank 3. Through the cooperation of each sensing convex tooth 10 on the sensing paddle 9 and the storage sensor 11 on the reagent storage mechanism, it is possible to accurately control the alignment of each reagent holding tank 3 with the reagent extraction mechanism, thereby improving the accuracy of control.

[0032] The reagent storage mechanism also includes a refrigeration component, which is connected to the reagent storage tray 2 and is used to cool down each detection reagent in the reagent storage tray 2. By setting up the refrigeration component, the detection reagent in the reagent storage tray 2 can be cooled down to meet the requirement of low temperature storage of the detection reagent; the possibility of deterioration of the detection reagent is reduced, thereby ensuring the accuracy of the detection result.

[0033] Specifically, the refrigeration assembly includes two refrigeration fins 12, and a heat preservation cover 13 is fixedly installed on the storage mounting frame 1. The heat preservation cover 13 is set on the periphery of the reagent storage tray 2. By setting the heat preservation cover 13, the temperature rise rate of the reagent storage tray 2 can be delayed, thereby playing a role in heat preservation for the detection reagent in the reagent storage tray 2. The two refrigeration fins 12 are respectively fixedly installed on the heat preservation cover 13, and the two refrigeration fins 12 are respectively arranged directly below the reagent storage tray 2; by controlling the operation of the refrigeration fins 12, the reagent storage tray 2 can be cooled, thereby achieving a cooling effect on the detection reagent in the reagent holding tank 3.

[0034] In this embodiment, the cooling temperature of the cooling plate 12 is controlled at 2-8° C. In other embodiments, the cooling temperature may also be controlled at other cooling temperatures.

[0035] In order to improve the heat preservation effect of the heat preservation sleeve 13, heat preservation cotton 14 is filled in the heat preservation sleeve 13. By filling the heat preservation cotton 14, the heat preservation performance of the heat preservation sleeve 13 can be improved, the working frequency of the refrigeration plate 12 can be reduced, and the energy consumption can be reduced.

[0036] In order to further improve the heat preservation effect, an end cover 15 is provided on the upper end surface of the heat preservation sleeve 13, and the end cover 15 and the heat preservation sleeve 13 can be opened and closed. A through hole 16 is provided on the end cover 15 at a position corresponding to the reagent extraction mechanism. By covering the end cover 15 in the heat preservation sleeve 13, a relatively closed space is formed in the heat preservation sleeve 13, which can reduce the conduction of heat and improve the heat preservation performance; when it is necessary to extract the detection reagent, the reagent extraction mechanism can be controlled to pass through the through hole 16 to extract the detection reagent from the reagent storage tray 2.

[0037] During the operation of the refrigeration plate 12, heat will inevitably be generated; in order to dissipate the heat of the refrigeration plate 12, a water-cooled heat sink 17 is installed on the storage mounting frame 1, and the water-cooled heat sink 17 is connected to the side of the refrigeration plate 12 away from the reagent storage tray 2. The water-cooled heat sink 17 is provided with a water inlet joint 18 and a water outlet joint 19, and the water inlet joint 18 and the water outlet joint 19 are respectively used for external circulating cooling water. During detection, the water inlet joint 18 and the water outlet joint 19 are respectively connected to the cooling system of the urine protein analyzer; the heat generated by the operation of the refrigeration plate 12 will be transferred to the water-cooled heat sink 17, and the heat on the water-cooled heat sink 17 will be taken away by connecting cooling water to the water inlet joint 18, and the water will flow out of the water-cooled heat sink 17 through the water outlet joint 19, thereby realizing the function of dissipating heat for the refrigeration plate 12.

[0038] The above-mentioned specific implementation mode is a preferred implementation mode of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation mode. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
