Description

Technical Field

[0001] This utility model relates to the field of diagnostic reagent technology, and in particular to a testing device for examining the stability of the opening of a diagnostic reagent. Background Technology

[0002] Currently, for diagnostic reagents susceptible to interference from atmospheric carbon dioxide, open-ended stability tests typically involve opening the reagent bottle and placing it in a biochemical analyzer to measure stability over 30 or 60 days. This method is time-consuming, and the concentration of carbon dioxide is difficult to control, significantly extending the reagent development cycle. To shorten the development cycle, a specific concentration of carbon dioxide is prepared and then delivered to a chamber containing the reagent to be tested for stability evaluation. While rapidly providing a suitable concentration of carbon dioxide facilitates quick and convenient stability testing of diagnostic reagents, uneven carbon dioxide concentration can affect the accuracy of the test results. Therefore, to address the aforementioned issues, it is necessary to develop a detection device for evaluating the open-ended stability of diagnostic reagents. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a detection device for examining the stability of the opening of diagnostic reagents, which is designed to address the shortcomings of existing technologies. This detection device facilitates the uniform distribution of carbon dioxide and improves the accuracy of the detection results.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A testing device for examining the stability of diagnostic reagent openings includes a main body and a sealing door. The main body has a rotating shaft inside, one end of which is connected to a motor. The rotating shaft has a perforated storage component, which has multiple placement cylinders adapted to the test reagents. Multiple first flow-dispersing components are located around the storage component, and multiple second flow-dispersing components are located below the storage component. A gas distributor connected to an air inlet pipe is located above each storage component. A carbon dioxide concentration sensor is located on one side above each layer of storage components. The carbon dioxide concentration sensor and a solenoid valve on the air inlet pipe are electrically connected to a controller.

[0006] As an improved technical solution, the storage component is a hollowed-out plate, the placement tube is a hollowed-out structure, and the top of the placement tube is open.

[0007] As an improved technical solution, the first turbulence component is a fan-shaped plate or trapezoidal plate with a hollow structure.

[0008] As an improved technical solution, the second agitator is an L-shaped plate arranged at an angle.

[0009] As an improved technical solution, two adjacent gas distributors are interconnected by a pipe.

[0010] As an improved technical solution, the gas distributor includes a hollow disc body with a through hole at the center and multiple conical bodies communicating with the disc body on the lower surface, with multiple air distribution holes on the conical bodies.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are:

[0012] The testing device for assessing the open-ended stability of diagnostic reagents includes a main body and a sealed door. Inside the main body is a rotating shaft, one end of which is connected to a motor. The shaft has a perforated placement component with multiple placement cylinders adapted to the test reagents. Multiple first-stage flow-dispersing components surround the placement component, and multiple second-stage flow-dispersing components are located below it. Above each placement component is a gas distributor connected to an inlet pipe. A carbon dioxide concentration sensor is located on one side above each layer of placement components. The carbon dioxide concentration sensor and a solenoid valve on the inlet pipe are electrically connected to a controller. In practical applications, the sealed door is opened, and the test reagent is placed into the placement cylinder of the placement component. The motor starts, causing the rotating shaft, placement component, and test reagent in the placement cylinder to rotate. Carbon dioxide gas enters the gas distributor inside the main body along the inlet pipe. After being evenly dispersed by the gas distributor, it participates in the test reagent stability test. The multiple first-stage and second-stage flow-dispersing components on the placement component work together to further disperse the carbon dioxide gas inside the main body, ensuring that the test reagent fully absorbs the carbon dioxide, thus guaranteeing the accuracy of the test reagent stability assessment. A concentration sensor detects the carbon dioxide concentration around each shelf component. When the concentration falls below a set value, the controller activates a solenoid valve on the air inlet pipe, allowing carbon dioxide to enter the main body and further replenish the concentration required for the stability test of the reagents. This detection device is rationally designed, ensuring uniform dispersion of carbon dioxide gas and constantly monitoring the concentration inside the main body, significantly improving the accuracy of the reagent stability test results.

[0013] The container is a perforated disc, and the placement tube is also perforated, with the top of the placement tube open. The perforated design of both the disc and the placement tube facilitates the circulation of carbon dioxide gas, allowing it to enter the reagent and be used for stability testing.

[0014] The first turbulence-dispersing component is a perforated fan-shaped or trapezoidal plate. This design is reasonable and simple, facilitating the dispersion of carbon dioxide gas around the placement component, which helps in the evaluation of the stability of the detection reagent.

[0015] The second turbulence-dispersing component is an L-shaped plate with an inclined orientation. This design is reasonable and simple in structure, facilitating the dispersion of carbon dioxide gas below the placement component, which is helpful for examining the stability of the test reagent.

[0016] Because adjacent gas distributors are interconnected by pipes, this design facilitates the entry of carbon dioxide gas into multiple gas distributors.

[0017] The gas distributor comprises a hollow disc with a central through-hole. Multiple conical sections connected to the disc are located on the lower surface of the disc, each with numerous gas distribution holes. A rotating shaft passes through the central through-hole, allowing carbon dioxide to enter the hollow disc via an inlet pipe and then the conical sections. The carbon dioxide then disperses evenly through the gas distribution holes in the conical sections, participating in the stability testing of the detection reagents. This gas distributor is rationally designed and achieves uniform dispersion of carbon dioxide gas. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] A testing device for evaluating the open-ended stability of diagnostic reagents, such as... Figure 1As shown, the device includes a main body 1 and a sealing door 2 (the sealing door is hinged to the main body). The main body 1 has a rotating shaft 3 inside, one end of which is connected to a motor 4. The rotating shaft 3 has a hollowed-out storage component 5 (a hollowed-out disc). The storage component 5 has multiple placement cylinders 6 (hollowed-out structure with open tops) adapted to the test reagents. The periphery of the storage component 5 has multiple first flow-dispersing components 7 (hollowed-out fan-shaped plates, or trapezoidal plates; only the structure of the fan-shaped plates is shown in the attached diagram). Below the storage component 5 are multiple second flow-dispersing components 8 (tilting...). Each storage component 5 has an L-shaped plate arranged at an angle. Above each storage component 5 is a gas distributor 10 connected to the air inlet pipe 9 (including a hollow disc 100, the disc 100 is fixed to the inner wall of the main body by a connecting plate, the center of the disc has a through hole through which the rotating shaft passes, and the lower surface of the disc has multiple conical bodies 101 connected to the disc, with multiple air distribution holes on the conical bodies 101). A carbon dioxide concentration sensor 11 is provided on one side above each storage component 5. The carbon dioxide concentration sensor 11 and the solenoid valve 90 on the air inlet pipe 9 are electrically connected to the controller 12.

[0022] In practical applications, the sealed door is opened, and the reagent to be tested is placed into the placement cylinder of the storage component. The motor starts, driving the rotating shaft, the storage component, and the reagent in the placement cylinder to rotate. Carbon dioxide gas enters the gas distributor inside the main body along the air inlet pipe, passes through the gas distribution holes on the conical body of the disc, and is evenly dispersed before participating in the stability test of the reagent. Multiple first turbulence components (perforated fan-shaped plates) and second turbulence components (tilted L-shaped plates) on the storage component work together to further disperse the carbon dioxide gas distributed inside the main body and around the storage component. The reagent to be tested fully absorbs the carbon dioxide, thus ensuring the accuracy of the stability test. The concentration of carbon dioxide around each layer of the storage component is detected by a concentration sensor. When the concentration is lower than the set value, the controller activates the solenoid valve on the air inlet pipe, allowing carbon dioxide to enter the main body and further replenish the carbon dioxide concentration required for the stability test of the reagent.

[0023] The placement component 5 is a perforated disc, and the placement tube 6 is also perforated with an open top. Both the disc and the placement tube are perforated, a reasonable design that facilitates the circulation of carbon dioxide gas into the test reagent for stability testing.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
