[0002] A pharmaceutical stability test chamber is an important piece of equipment specifically designed to simulate the stability of pharmaceuticals under different environmental conditions. It is widely used in the pharmaceutical industry, research institutions, and quality control laboratories. The design principle of this equipment is to simulate various environmental conditions to ensure the stability of pharmaceuticals under different temperature and humidity conditions. Its main components include a temperature control system, a humidity control system, an air circulation system, sensors, and a data recording system.

[0003] As the name suggests, a multi-chamber drug stability test chamber is a type of chamber that contains multiple independent chambers, allowing for multiple tests to be conducted simultaneously, thereby improving experimental efficiency. Each chamber can also independently control temperature and humidity to meet different experimental needs.

[0004] However, when using this type of multi-chamber drug stability test chamber to conduct high-temperature tests on volatile drugs, some volatile drugs will remain in the test chamber after the test. The remaining drugs may affect the next drug to be tested in the same test chamber, thus affecting the test results of the equipment. Therefore, it does not meet the existing requirements. In response, we have proposed a multi-chamber drug stability test chamber. Utility Model Content

[0005] The purpose of this invention is to provide a multi-chamber drug stability test chamber to solve the problems mentioned in the background art, such as the residual volatile drug in the test chamber after the high-temperature test of volatile drugs, which may affect the next drug to be tested in the same test chamber, thus affecting the test effect of the equipment.

The output shaft of the stepper motor is connected to a transmission shaft via a coupling. The rear end face of the transmission shaft is connected to a threaded rod with opposite threads on both sides of the outer surface of the threaded rod. An internal threaded sleeve matching the external thread is fitted on both sides of the outer surface of the threaded rod. A square metal block is fixedly connected to the lower end face of the internal threaded sleeve. A sponge sleeve is fitted on both sides of the outer surface of the square metal block, and the outer surface of the sponge sleeve is in contact with the inner wall of the test chamber.

[0008] Preferably, a guide rod is provided on the upper side of the interior of the test chamber, both ends of which are fixed to the inner wall of the test chamber, and the guide rod moves laterally through the square metal block and sponge sleeve located inside the test chamber.

This utility model, when a volatile drug is subjected to a high-temperature test in the test chamber located at the top of a multi-chamber drug stability test chamber, and volatile drugs remain inside, sprays water into the test chamber through a corresponding spray head. The water's absorbent properties draw the remaining drugs into the water. Simultaneously, a stepper motor moves a sponge sleeve back and forth inside the test chamber to wipe the inner wall. After the sponge sleeve has moved back and forth for five minutes, a small water pump extracts the water containing the drugs from inside the test chamber. This technical solution automatically cleans the volatile drugs inside the test chamber. Attached Figure Description

Detailed Implementation

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] The multi-chamber drug stability test chamber 1 (model ZW-00821065), stepper motor 5 (model 42D5417-02), and small water pump 12 (model DC41B) mentioned in this utility model can all be purchased from the market or customized.

[0021] Please see Figures 1 to 3 The present invention provides an embodiment of a multi-chamber drug stability test chamber, comprising a multi-chamber drug stability test chamber 1, wherein the multi-chamber drug stability test chamber 1 is provided with multiple test chambers 2 inside, and a spray head 4 fixedly installed inside the multi-chamber drug stability test chamber 1 is provided above the test chambers 2.

[0022] A stepper motor 5 is fixedly installed inside the multi-chamber drug stability test chamber 1 in front of the spray head 4. The output shaft of the stepper motor 5 is connected to the transmission shaft 14 through a coupling. The rear end face of the transmission shaft 14 is connected to a positive and negative threaded rod 6. The threads on both sides of the outer surface of the positive and negative threaded rod 6 are opposite. Both sides of the outer surface of the positive and negative threaded rod 6 are fitted with an internal threaded sleeve 7 that matches its external thread. A square metal block 8 is fixedly connected to the lower end face of the internal threaded sleeve 7. Both sides of the outer surface of the square metal block 8 are fitted with a sponge sleeve 9, and the outer surface of the sponge sleeve 9 is in contact with the inner wall of the test chamber 2.

[0023] A control panel 15 is fixedly installed on one side of the outer surface of the multi-chamber drug stability test chamber 1, and the multi-chamber drug stability test chamber 1, the spray head 4, the stepper motor 5 and the small water pump 12 are all electrically connected to the control panel 15; the multi-chamber drug stability test chamber 1, the spray head 4, the stepper motor 5 and the small water pump 12 can be controlled through the control panel 15.

[0024] One side of the upper end of the spray head 4 is connected to a water inlet pipe 3, and the other end of the water inlet pipe 3 is connected to the mixing tank. When a volatile drug is subjected to a high-temperature test in the test chamber 2 located at the top of the multi-chamber drug stability test chamber 1, and there are volatile drugs remaining inside, water and adsorbent are added to the inside of the mixing tank. Then, the two are mixed evenly through the mixing tank. After that, the water mixed with adsorbent is transmitted to the corresponding spray head 4 through the water inlet pipe 3, and the water is sprayed into the inside of the test chamber 2 through the spray head 4. Through the adsorption of this water, the drug remaining in the test chamber 2 can be adsorbed into the water. The adsorbent can also enhance the adsorption effect of the water on the residual drug.

[0025] A guide rod 10 is provided on the upper side inside the test chamber 2. Both ends of the guide rod 10 are fixed to the inner wall of the test chamber 2, and the guide rod 10 moves laterally through the square metal block 8 and the sponge sleeve 9 located inside the test chamber 2. Because the guide rod 10 moves laterally through the square metal block 8 and the sponge sleeve 9, neither the square metal block 8 nor the sponge sleeve 9 can rotate. When the spray head 4 is opened, the stepper motor 5 is started, which drives the connected positive and negative threaded rod 6 to rotate. When the positive and negative threaded rod 6 rotates, it is threaded onto the outer surface of the spray head 8, but because it is fixed to the square metal block 8, it causes itself to... The non-rotating internal threaded sleeve 7 will move back and forth under the transmission of the threaded structure. Since the threads on both sides of the outer surface of the positive and negative threaded rod 6 are opposite, when the positive and negative threaded rod 6 rotates, the two internal threaded sleeves 7 respectively sleeved on both sides of the outer surface of the positive and negative threaded rod 6 will move inward or outward synchronously. During the movement of the internal threaded sleeve 7, the square metal block 8 fixed to it and the sponge sleeve 9 sleeved on the outer surface of the square metal block 8 will move synchronously. The sponge sleeve 9 moving back and forth inside the test chamber 2 can wipe the inner wall of the test chamber 2, thereby cleaning away the volatile medicine adhering to the inner wall of the test chamber 2.

[0026] A small water pump 12 is fixedly installed inside the multi-chamber drug stability test chamber 1 at the front of the square metal block 8. The rear end of the small water pump 12 is connected to a water suction pipe 11 that communicates with the inside of the test chamber 2. The front end of the small water pump 12 is connected to a drain pipe 13, and the front end of the drain pipe 13 is connected to a wastewater collection tank. After the sponge sleeve 9 moves back and forth for five minutes, the water containing the drug inside the test chamber 2 is drawn out through the water suction pipe 11 on the small water pump 12 and transferred to the wastewater collection tank through the drain pipe 13. Through the above technical solution, the drug volatilized inside the test chamber 2 can be automatically cleaned up, thereby improving the functionality of the equipment.

[0027] After the water inside the test chamber 2 is pumped out, turn off the spray head 4, but do not turn off the small water pump 12 and the stepper motor 5 for the time being. When the stepper motor 5 drives the sponge sleeve 9 to move back and forth, the sponge sleeve 9 will also absorb some water. When the water inside the test chamber 2 is pumped out and the spray head 4 is turned off, as the sponge sleeves 9 located on both sides inside the test chamber 2 move, the sponge sleeves 9 facing the inner wall of the test chamber 2 will squeeze against each other with the inner wall of the test chamber 2, and the two sponge sleeves 9 in opposite positions will squeeze against each other to squeeze out the water absorbed by the sponge sleeves 9. When the sponge sleeves 9 can no longer squeeze out water, move the sponge sleeves 9 back to their original position through the stepper motor 5, and then turn off the stepper motor 5 and the small water pump 12.

[0028] When the interior of test chamber 2 is cleaned and it is needed to be used again, the required medicine is added inside test chamber 2, and then the environment inside test chamber 2 is changed by using multi-chamber medicine stability test chamber 1.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
