A device for detecting air tightness of heparin sodium raw material container

Abstract

The invention provides an air tightness detection device for a sodium heparin raw material container, relates to the technical field of detection devices, and comprises: a mounting component; the mounting component comprises a frame, a bottom groove and an insertion rod, and the frame is a cross-shaped structure; during detection, the sealed container is placed in a groove-shaped space surrounded by a surrounding plate, and air is blown into the space. During the blowing process, the air pressure in the surrounding plate increases, so that the lifting plate pushes the sphere to rise through the supporting plate. If a group of containers on the inner side of the surrounding plate leaks, a part of the air pressure in the surrounding plate will enter the container, which causes the air pressure in the surrounding plate to decrease, the rising speed of the lifting plate to decrease, and the sphere will tilt toward the supporting plate on this side. Through such an arrangement, the air tightness of the container can be intuitively judged through a simple structure, thereby solving the problem that the detection device mainly relies on a barometer or an air pressure sensing structure, and the detection device with such a detection structure not only has a high manufacturing cost, but also has a high maintenance cost in the later stage.

Description

Technical Field

[0001] The invention relates to the technical field of detection devices, and in particular to an airtightness detection device for a heparin sodium raw material container. Background Art

[0002] Heparin sodium is a common drug. After production, most microorganisms are killed through a sterilization process, and it can be stored for a long time at room temperature under closed and vacuum conditions. The airtightness of the storage container determines the quality and pass rate of the heparin sodium drug. Therefore, before storage, the airtightness of the storage container needs to be tested by testing equipment to avoid microbial contamination of the internal heparin sodium due to container leakage.

[0003] For example, the application number: CN202122148863.1 involves an overall sealing detection device for an ink tank, including an ink tank and a detection device body, a vacuum assembly, a sealing detection assembly and a lifting assembly. The vacuum end of the vacuum assembly is connected to the air compressor through a pipeline. The vacuum assembly performs vacuum sealing on the cavity after the sealing cover and the platform are closed. The sealing detection assembly is installed on the top of the sealing cover. The sealing detection assembly includes a second vacuum pressure gauge and a pinhole drill. The second vacuum pressure gauge detects the vacuum pressure value in the ink tank cavity. The lifting assembly is installed in the detection device body. The lifting assembly includes a lifting platform embedded on the platform. The lifting assembly lifts the lifting platform to make the ink tank contact with the sealing detection assembly. The overall sealing detection device for the ink tank designed by the utility model can not only meet the requirements of sealing the ink tank after vacuuming, but also detect the vacuum degree of the ink tank, with high detection efficiency and high detection quality.

[0004] However, there are some shortcomings in the design of current container sealing detection equipment. First, in order to ensure the accuracy of the test results, the existing detection device can only detect the sealing of a group of containers at a time, which leads to low detection efficiency of the detection device. Secondly, the existing detection device mainly relies on a barometer or an air pressure sensing structure.
