Description

Technical Field

[0001] The utility model relates to the technical field of drug package detection and analysis equipment, and more specifically to a drug packaging material analysis device which is easy to clean. Background Art

[0002] Pharmaceutical packaging testing instruments mainly include pharmaceutical packaging material barrier performance testing (gas permeability test and water vapor permeability test), etc.

[0003] A negative pressure detector is a device that generates a pressure difference between the inside and outside of a sample immersed in water by evacuating a vacuum chamber to create a negative pressure, and observes the escape of gas from the sample to determine the sealing performance of the sample; or it generates a pressure difference between the inside and outside of the sample by evacuating a vacuum chamber, and observes the expansion of the sample and the recovery of its shape after the vacuum is released to determine the sealing performance of the sample. A vacuum pump is provided in the negative pressure detector to evacuate the vacuum barrel. However, the existing negative pressure detector has the problem that the vacuum pump vibrates during use and affects the use of the vacuum barrel, causing the vacuum barrel to fall or be damaged due to vibration. The existing patent is a negative pressure detector with a position-limiting structure. The negative pressure detector with a position-limiting structure in patent authorization number CN216955051U reduces the impact of the vacuum pump inside the negative pressure detector controller body vibrating during use.

[0004] The possibility of using the vacuum tank is reduced while reducing the noise generated by the device.

[0005] However, when the vacuum barrel in patent authorization number CN216955051U performs sealing detection on the drug package, if the sealing of the drug package is not good, the drug package will burst, so that the drug adheres to the inner wall of the vacuum barrel, and manual cleaning is required, which is very inconvenient. Therefore, we propose a drug packaging material analysis device that is easy to clean to solve the above problems. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a drug packaging material analysis device which is easy to clean.

The upper surface of the barrel cover 4 is fixedly connected with a bracket 8. A driving motor 9 is installed on the top of the bracket 8. A driving gear 10 is installed at the power output end of the driving motor 9.

A driven gear 12 meshing with the driving gear 10 is installed at the top of the connecting shaft 11. The bottom end of the connecting shaft 11 is connected to a connecting frame 14 located in the inner cavity of the vacuum detection barrel 3, and the connecting frame 14 is arranged in an inverted L-shaped structure. A brush 15 connected to the inner wall of the vacuum detection barrel 3 is installed at the connecting frame 14;

[0032] It should be noted that when the easy-to-clean drug packaging material analysis device is used, firstly, a proper amount of water is added to the inner side of the vacuum detection barrel 3, and then the drug package to be detected is placed below the water surface, and the barrel cover 4 is installed on the top of the vacuum detection barrel 3 and connected to the negative pressure detector body 1 through the vacuum tube 2 for vacuuming;

[0033] When bubbles appear inside the vacuum detection barrel 3, it means that the sealing effect of the drug package is not good. After the drug package bursts, the driving motor 9 is turned on to drive the driving gear 10 to rotate and drive the driven gear 12 to operate, so that the connecting shaft 11 drives the connecting frame 14 to rotate. At the same time, the second sealing rubber ring 13 is used to ensure the airtightness of the joint between the connecting shaft 11 and the barrel cover 4. The bristles 15 are attached to the inner wall of the vacuum detection barrel 3 for cleaning, so that the medicine attached to the joint between the liquid surface and the inner wall of the vacuum detection barrel 3 can be cleaned, eliminating the tedious operation of manual cleaning. The cleaning is very convenient. After the cleaning is completed, the barrel cover 4 is opened to pour out the water in the vacuum detection barrel 3.

[0034] like Figure 3 , Figure 6 As shown, a cover 16 is placed inside the vacuum detection barrel 3, and a through hole 17 is opened in an array on the top of the cover 16;

[0035] It should be noted that by placing the drug package to be tested on the inner side of the cover 16, and then placing the cover 16 upside down in the vacuum test barrel 3 and sinking it to the bottom of the water to prevent interference with the connecting frame 14, it is helpful to clean the inner wall of the vacuum test barrel 3.

[0037] It should be noted that the connection between the vacuum detection barrel 3 and the barrel cover 4 is facilitated, while the air tightness of the joint between the vacuum detection barrel 3 and the barrel cover 4 is ensured.

[0038] like Figure 3As shown, the vacuum detection barrel 3 is made of transparent glass, and the cover 16 is made of stainless steel;

[0039] It should be noted that the air tightness of the drug package can be conveniently checked through the vacuum detection barrel 3, and the drug package can be completely immersed below the liquid surface through the cover 16.

[0040] like Figure 1 , Figure 3 As shown, a connection port 18 is provided on the upper surface edge of the barrel cover 4, and the connection port 18 is plugged and connected to the vacuum tube 2;

[0041] It should be noted that the vacuum detection barrel 3 is subjected to a vacuum treatment.

[0042] When in use: first add a proper amount of water to the inner side of the vacuum detection barrel 3, then place the drug package to be detected below the water surface, install the barrel cover 4 on the top of the vacuum detection barrel 3 and connect it to the negative pressure detector body 1 through the vacuum tube 2 to perform vacuuming;

[0043] When bubbles appear inside the vacuum detection barrel 3, it means that the sealing effect of the drug package is not good. After the drug package bursts, the driving motor 9 is turned on to drive the driving gear 10 to rotate and drive the driven gear 12 to operate, so that the connecting shaft 11 drives the connecting frame 14 to rotate. At the same time, the second sealing rubber ring 13 is used to ensure the airtightness of the joint between the connecting shaft 11 and the barrel cover 4. The bristles 15 are attached to the inner wall of the vacuum detection barrel 3 for cleaning, so that the medicine attached to the joint between the liquid surface and the inner wall of the vacuum detection barrel 3 can be cleaned, eliminating the tedious operation of manual cleaning. The cleaning is very convenient. After the cleaning is completed, the barrel cover 4 is opened to pour out the water in the vacuum detection barrel 3.

[0044] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
