At present, the chemical stability and airtightness of medicinal liquid infusion containers are still important criteria for assessing their qualification rate in medical devices. There are three main types of medicinal infusion containers in China: glass bottles, plastic bottles, and infusion soft bags. Glass infusion bottles are heavy, have high transportation costs, large volume, occupy a large space, are fragile, and are prone to bottle breakage and contamination, making them inconvenient to use. Therefore, they have gradually been replaced by the latter two. Therefore, the application of infusion soft bags and plastic infusion bottles is becoming increasingly widespread. In order to ensure the quality and safety of infusion bags, the modern medical industry has developed a sealing tester for medicinal infusion bags through technological means to verify whether the sealing of medicinal infusion bags is qualified.

The sealing tester for medicinal infusion bags uses high-precision pressure sensors to place infusion bottles on top and apply pressure for testing. By measuring pressure changes, determine whether there are any leakage points in the infusion bag, and thus evaluate the sealing of the infusion bag. This detection instrument is suitable for infusion bags and soft bags of different capacities, specifications, and shapes, and has the characteristics of accuracy, speed, and convenience.

Instructions for use

(1) Put an appropriate amount of distilled water into the vacuum sealed tank (i.e. vacuum chamber) and immerse the infusion bag sample into the water. At this time, the distance between the top of the sample and the water surface shall not be less than 25 mm.

(2) Cover with a sealing cap to ensure that there is no air leakage around the sealing cap and that the sealing can is well sealed.

(3) Set the test parameters such as the required vacuum degree (i.e. negative pressure value) and the holding time inside the vacuum tank through the microcomputer operation interface.

(4) Turn on the vacuum pump, click the test button, and the test begins.

(5) Observe the leakage of the sample during the vacuum pumping and pressure holding process, and observe whether there are continuous bubbles generated.

(6) If there are continuous bubbles generated on the surface of the sample, record the pressure value and the location of the bubbles when they appear.

(7) Turn off the vacuum pump, connect the vacuum chamber to the atmosphere, open the sealing cover, take out the sample, wipe off the water on its surface, and if necessary, open it to check if there is any test water seeping into the interior of the sample.

(8) Turn off the power of the instrument.

Overall, as a professional testing equipment, the infusion bottle sealing tester plays an important role in improving the quality control and product safety of the medical industry. It not only ensures the health and safety of patients, but also enhances the reputation and brand image of medical institutions. We believe that with the combination of advanced technology and human intelligence, the sealing tester for medicinal infusion bags will contribute to the development of the medical industry and become the guardian of medical safety.
