Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a full-automatic urine protein analyzer. Background Art

[0002] The specific protein analyzer is an analytical instrument used to measure the content of specific proteins in human body fluids. It uses the principle of laser scattering turbidimetry to measure the turbidity of the solution after the reaction of the sample and reagent in the reaction cup to determine the level of specific protein content in the sample. The level of specific protein content reflects the corresponding state of the patient's body and provides effective reference data for doctors' diagnosis.

[0003] First, the immune response is sensitive to temperature, and the reliability of the test results can only be guaranteed in the appropriate temperature environment for the tested samples and reagents. However, the incubation tray for incubating samples in the prior art is heated unevenly and has a large temperature difference, which has a great impact on the analysis and diagnosis results.

[0004] Second, most specific protein analyzers are semi-automatic specific protein analyzers, and their typical feature is that they require a lot of manual operation. Therefore, there are problems such as low efficiency, large errors, large reagent usage, and high cost. They often require inspectors with high professional skills to operate. And currently, in the analysis device for liquid samples, after the sampling needle absorbs the sample or reagent, the sample will remain on the inner and outer surfaces of the sampling needle, so the sampling needle needs to be cleaned to avoid interference with the next sample test. The existing specific protein analyzers have poor cleaning effects, large carryover contamination, cumbersome operations, and a long time.

[0005] Third, the optical path detection mechanism of the specific protein analyzer in the prior art has a fixed halogen lamp position. If the halogen lamp position is offset, causing the optical signal detected by the CCD charge coupled device to exceed or fail to reach the required intensity, it will affect the detection result.

[0066] The incubation plate mechanism 92 , the sampling mechanism 93 , the flushing assembly 94 , and the optical path detection assembly 95 are arranged on the bottom plate 1 .

[0067] like Figure 3-4 As shown, the incubation tray mechanism 92 includes a placement tray 2, and the placement tray 2 includes a reaction cup rack 201 and a sample reagent rack 202. The reaction cup rack 201 is annular, and the reaction cup rack 201 is evenly provided with a plurality of reaction cup placement holes 2011 along the circumferential direction. The reaction cup rack 201 includes a plurality of fan-shaped cup rack pieces. The sample reagent rack 202 includes an upper frame and a lower frame, and the upper frame and the lower frame are fixedly connected by a plurality of frame connecting columns 12. The upper frame and the lower frame are both disc-shaped. A plurality of urine collection tube placement holes 2021 and reagent placement holes 2022 are evenly provided on the upper frame along the circumferential direction. The reaction cup rack 201 is fixedly connected to the edge of the upper frame. Therefore, the reaction cup rack 201 and the sample reagent rack 202 are separately arranged, so that the temperature transfer between the reaction cup rack 201 and the sample reagent rack 202 is slow.

[0068] A main shaft turntable 11 is disposed at the bottom of the lower frame. A rotating motor 10 is connected to the main shaft turntable 11 . The rotating motor 10 is fixedly mounted on the bottom plate 1 .

[0069] A cooling plate 3 is provided below the lower frame, and the cooling plate 3 is fixedly connected to the bottom plate 1 through a plurality of cooling plate mounting columns 13. A heat preservation component 4 is provided below the reaction cup holder 201 and the upper frame. The upper frame, the heat preservation component 4 and the cooling plate 3 form a first accommodating space, and the reaction cup holder 201 and the heat preservation component 4 form a second accommodating space, in which a heating component is provided.

[0070] In this embodiment, the heat preservation component 4 includes an inner heat preservation ring 401 and an outer heat preservation ring 402, wherein the inner heat preservation ring 401 is fixedly connected to the edge of the refrigeration plate 3, and the outer heat preservation ring 402 is arranged on the outer periphery of the inner heat preservation ring 401. The outer heat preservation ring 402 is installed on the bottom plate 101 through a plurality of heat preservation ring installation columns 14.

The radiator 6 is connected to a cooling fan 7. The cooling fan 7 is installed below the radiator 6 through a fan mounting bracket 8.

[0072] The semiconductor cooling plate 5 is a heat transfer tool. When a current passes through a thermocouple formed by connecting an N-type semiconductor material and a P-type semiconductor material, heat transfer will occur between the two ends, and the heat will be transferred from one end to the other end, thereby generating a temperature difference to form a cold and hot end. However, the semiconductor itself has resistance. When current passes through the semiconductor, heat will be generated, which will affect heat transfer. In addition, the heat between the two plates will also be reversely transferred through the air and the semiconductor material itself. When the cold and hot ends reach a certain temperature difference and the amount of these two heat transfers is equal, an equilibrium point will be reached, and the positive and reverse heat transfers will cancel each other out. At this time, the temperature of the cold and hot ends will not continue to change. In order to achieve a lower temperature, the temperature of the hot end can be reduced by heat dissipation or other methods.

[0073] The cooling fan 7 and the radiator 6 are mainly used to dissipate heat from the hot end of the semiconductor refrigeration chip 5. Usually, the temperature difference between the hot and cold ends of the semiconductor refrigeration chip 5 can reach 40 to 65 degrees. If the hot end temperature is lowered by active heat dissipation, the cold end temperature will also drop accordingly, thereby reaching a lower temperature.
