Infusion tubes are a common medical consumable in the medical field. They are usually sterile treated and then packaged.The air tightness of the infusion tube is very important. If the air tightness is not good, it will be easily damaged, and if you are not careful, the infusion tube will be contaminated.Therefore, it is very necessary to conduct sealing testing of infusion tubes.

As an expert in sealing testing and a developer of sealing equipment, Hirays Technology also has special research on the sealing testing of this infusion tube.

one, The necessity of testing the tightness of infusion tubes

The sealing integrity of the infusion tube is related to the quality and safety of medicines.If the sealing performance is not up to standard, external impurities will enter the infusion tube and contact the internal medicine, and the medicine will deteriorate, fail, and even harm the patient's health.

Therefore, the infusion tube must have a perfect seal throughout its validity period, and the infusion tube must undergo professional and strict sealing performance testing.Testing the sealing performance of the infusion tube is to test its air tightness. This test can ensure that the entire product seal is complete and leak-free.In the pharmaceutical industry, it is essential to conduct sealing testing of the infusion tubes produced, which will directly determine whether the quality of the medical treatment meets the standards and whether it will pose a threat to human safety.

two, Difficulties in detecting infusion tubes

Generally, the shape of the infusion tube is an irregular long strip. In addition to the long transparent soft rubber tube that is sealed, air can directly enter the two ends connecting the infusion bottle and the needle.Infusion tubes, as one of the medical devices, have the same characteristics as other medical devices. They are easily damaged, easily deformed, and have complex structures. In addition, they also have problems in detection due to difficulty in fixing and small size, making it difficult to accurately control the detection.

two, How to check the tightness of infusion tubes

Hirays Technology uses indirect sealing testing for infusion tubes. Because the diameter of the infusion tube is small and the rubber hose of the infusion tube is easy to fold, the irregular-shaped flow rate regulator and liquid filter in the middle cannot fix the infusion tube well. Therefore, the infusion tube needs to be put into a special mold, so that during the test, the upper and lower parts of the mold can be closed to form a good sealing state.And the gas filled into the mold uses compressed air as the detection medium, and the mold is directly inflated. Liquid detection is not used to avoid unnecessary contamination of the infusion tube.
