Description

Technical Field

[0001] The invention relates to the technical field of experimental equipment, in particular to a drug testing system with an air duct circulation device. Background Art

[0002] Drug stability test chambers are used in the pharmaceutical, medical, and biotechnology industries. They simulate temperature, humidity, and light conditions in the environment, providing a scientific basis for drug production, packaging, storage, and transportation conditions. They also determine the drug's shelf life through testing.

[0003] Currently, the common air duct circulation devices on the market usually discharge reflux gas at a fixed position. However, in actual applications, drugs may face various complex airflow environments. Traditional air duct circulation devices are difficult to simulate real scenarios such as airflow differences caused by changes in air pressure at different altitudes, and changes in wind direction and wind speed under different climatic conditions. At the same time, when facing different drug experiments, the airflow cannot be adjusted accordingly according to different products, which affects the accuracy and repeatability of the test results.

[0004] Therefore, in order to solve the above problems, a drug testing system with an air duct circulation device is proposed. Summary of the Invention

[0005] In order to make up for the shortcomings of the prior art and the problem of limited real environment simulation, the present invention provides a drug testing system with an air duct circulation device.

[0007] Preferably, a filter element is fixedly installed inside the purification cylinder, and a cylinder cover is fixedly installed on the top of the purification cylinder.

[0008] Preferably, air inlets are provided at the four corners of the test box, and a rectangular air outlet is provided on one side of the L-shaped air duct close to the test box, and the rectangular air outlet is matched with the air inlet.

[0009] Preferably, a plurality of heating rods are fixedly mounted on the top of the inner cavity of the test box, a humidifier is fixedly mounted on one side of the top of the test box, and an atomizing nozzle is fixedly mounted on the surface and the end of the humidifier output pipe.

[0010] Preferably, a plurality of slide rails are fixedly installed on both sides of the inner cavity of the test box, and a bearing plate is movably installed inside the slide rails.

[0011] Preferably, a control panel is fixedly mounted on one side of the test box, and a temperature and humidity sensor is fixedly mounted on the back of the control panel.

[0012] Preferably, a door is movably installed on the front of the test box, and a transparent window is opened on the front of the door.

[0013] The beneficial effects of the present invention are:

[0014] 1. The present invention realizes the function of multi-dimensional airflow regulation through the structural design of L-shaped air duct, adjustment motor, threaded rod, sealing plate, vent group, and connecting ear. Therefore, multi-dimensional airflow regulation can be achieved by adjusting the exhaust port up and down, thereby simulating more complex and real-life airflow conditions, so that the airflow impact on the drug during the test is closer to the actual use or storage conditions, thereby improving the accuracy and reliability of the test results. At the same time, the airflow in the test equipment can be more evenly distributed in every corner, ensuring that the drug samples at each position are affected by the same airflow conditions, solving the problem of limited real-life environment simulation.

Therefore, multi-dimensional airflow regulation can be achieved by adjusting the exhaust port up and down, thereby simulating a more complex and real-life airflow condition, so that the airflow effect on the drug during the test is closer to the actual use or storage situation, thereby improving the accuracy and reliability of the test results. At the same time, the airflow in the test equipment can be more evenly distributed in every corner, ensuring that the drug samples at each position are affected by the same airflow conditions.

[0026] A filter element 10 is fixedly installed inside the purification cylinder 3 , and a cylinder cover 11 is fixedly installed on the top of the purification cylinder 3 .

[0027] Reference Figure 1 and Figure 4 By setting the filter element 10, it is convenient to filter the recycled gas, thereby ensuring the purity of the gas inside the experimental equipment and reducing the interference of impurities in the air on the medicine. By setting the cylinder cover 11, it is convenient to close the top opening of the purification cylinder 3, thereby preventing external air from invading the interior of the equipment, and at the same time, it is also convenient for subsequent users to quickly disassemble and install the filter element 10.

[0029] Reference Figure 3 and Figure 4 The setting of the air inlet 12 facilitates the provision of space for the purified gas to enter the interior of the test box 1. At the same time, the air inlet at the four corners can reduce the dead corners of the air flow in the test box 1, thereby ensuring the uniform flow of gas inside the test box 1. The setting of the rectangular air outlet 13 facilitates the coordination with the air inlet 12, so that the air in the L-shaped air duct 4 can fully enter the test box 1.

The setting of the carrier plate 18 facilitates the placement of drug test samples and provides stable support for the test samples, thereby ensuring the stability of the test samples during the experiment.

[0034] A control panel 19 is fixedly mounted on one side of the test box 1 , and a temperature and humidity sensor 20 is fixedly mounted on the back of the control panel 19 .

[0035] Reference Figure 1 and Figure 3 By setting the temperature and humidity sensor 20, it is convenient to monitor the temperature and humidity in the test box 1 in real time, and feed the data back to the control panel 19 so as to adjust the equipment operating parameters in time.

[0036] A door 21 is movably mounted on the front of the test box 1 , and a transparent window 22 is provided on the front of the door 21 .

[0037] Reference Figure 1 The transparent window 22 is provided to facilitate the staff to observe the internal operating status of the test box 1 in real time so as to take corresponding measures in time.

[0038] Working principle: When using this device, open the control panel 19, set the temperature, humidity and other parameters required for the test, heat the air inside the test box 1 through the heating rod 14, humidify the air inside the test box 1 through the humidifier 15 and the atomizing nozzle 16, place the experimental drug through the carrier plate 18, place it inside the slide rail 17 through the carrier plate 18, complete the placement of the experimental drug, start the fan 2, force the air inside the test box 1 to flow through the fan 2, and transport the gas inside the test box 1 to the purification cylinder 3 through the fan 2, filter the gas through the filter element 10, and transport the filtered gas to the rectangular exhaust port 13 through the L-shaped air duct 4, drive the threaded rod 6 to rotate by adjusting the motor 5, and convert the rotational motion into linear motion through the threaded rod 6 and the connecting ear 9 to drive the sealing plate 7 to rise and fall, and adjust the vent group 8 to the predetermined position of the simulated environment through the sealing plate 7, and then seal the blank area of ​​the rectangular exhaust port 13 through the sealing plate 7, and the gas enters the test box 1 through the vent group 8 and the air inlet 12.
