DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail by combining with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0021] A device for detecting the opening stability of diagnostic reagents, such as Figure 1 As shown, the device includes a main body 1, inside which is a reaction chamber 2 and multiple gas storage chambers 3 (with a sealing door 32 on the outer wall, the sealing door is hinged to the gas storage chambers). The reaction chamber 2 is located at the center of the main body and is connected to the multiple gas storage chambers 3 through an exhaust pipe 4. Each gas storage chamber 3 has a placement rack 5 and a gas dispersion component 6 inside. The top of the reaction chamber 3 has a first feed pipe 20 and a second feed pipe 21, and the bottom of the reaction chamber 1 has an outlet pipe 22. The inside of the reaction chamber 1 has a rotating shaft 7 and a carbon dioxide concentration sensor 8. One end of the rotating shaft 7 is connected to a motor 9, and the rotating shaft 7 has a stirring component 70 (a multi-layer hollow structure stirring plate). The solenoid valves 11 and flow meters 10 on the first feed pipe 20 and the second feed pipe 21, the solenoid valve 40 on the exhaust pipe 4, the gas dispersion component 6, and the carbon dioxide concentration sensor 8 are electrically connected to a controller 12.

[0022] In practical applications, the detection reagents are first placed on the rack in the gas storage chamber. A certain concentration of citric acid solution and sodium bicarbonate solution are then added to the reaction chamber through the first and second inlet pipes. The motor starts, driving the rotating shaft and stirring components to ensure thorough contact and reaction between the citric acid and sodium bicarbonate. When the carbon dioxide concentration sensor detects the set concentration value, the solenoid valve on the reaction chamber exhaust pipe opens, allowing carbon dioxide gas to enter the corresponding gas storage chamber. After dispersion by the gas dispersion component, the gas is then used to test the stability of the detection reagents. After one carbon dioxide concentration test is completed, the detection reagents are placed on the rack in another gas storage chamber. The carbon dioxide of a suitable concentration prepared in the reaction chamber then enters the gas storage chamber, dispersed by the gas dispersion component, and used to test the stability of the detection reagents. This process is repeated for the next carbon dioxide concentration test. This detection device is rationally designed, easy to operate, and can provide the appropriate carbon dioxide concentration required by the detection reagents, significantly shortening the reagent development cycle.

[0023] The plurality of gas storage chambers 3 include a first gas storage chamber 30 and a second gas storage chamber 31. Carbon dioxide of different concentrations used for testing the stability of reagents after opening is stored in the first gas storage chamber and the second gas storage chamber respectively, which is convenient for testing the stability of the reagents.

[0024] The gas dispersion component 6 comprises a pipeline 60 communicated with the exhaust pipe 4, the exhaust pipe 4 is provided with an air draught fan 14, the exhaust end of the pipeline 60 is provided with a hollow conical part 62, the bottom of the conical part 62 is provided with a plurality of exhaust holes, and the air draught fan 61 is electrically connected with the controller 12. The controller starts the air draught fan, the carbon dioxide gas in the reaction chamber enters the conical part along the exhaust pipe, and is uniformly dispersed through the exhaust holes, so that the dispersion of the carbon dioxide gas is realized, and the stability of the detection reagent is more conducive to investigation.

[0025] The upper and lower parts of the inside of the first gas storage chamber 30 and the second gas storage chamber 31 are respectively provided with fans 13, and the fans 13 are electrically connected with the controller 12. The controller starts the fan to run, and the carbon dioxide gas is circulated in the inside of the gas storage chamber through the fan, so that the uniformity of the carbon dioxide concentration is ensured, and the accuracy of the detection result of the detection reagent is facilitated.

[0026] The placing rack 5 is provided with a plurality of placing plates 50, and each placing plate 50 is provided with a plurality of detection reagent placing grooves 500. The design is reasonable, the structure is simple, the detection reagent is fixed, and the stability is convenient to investigate.

[0027] The inside of the first gas storage chamber 30 and the second gas storage chamber 31 is respectively provided with a carbon dioxide concentration sensor 8, and the carbon dioxide concentration sensor 8 is electrically connected with the controller 12. With the absorption of the detection reagent to the carbon dioxide, the concentration of the carbon dioxide is reduced, and when the concentration detected by the carbon dioxide concentration sensor is lower than the set value, the material of the reaction chamber can be used to prepare carbon dioxide, and then the carbon dioxide is transported to the inside of the gas storage chamber to continue to investigate the stability of the detection reagent.
