Description

Technical Field

[0001] The present invention relates to the technical field of infusion bottle bag detection, and in particular to a device, method and application for detecting welding integrity of a sealing surface of an infusion bottle bag. Background Art

[0002] When treating patients in hospitals, drugs are often infused into patients through intravenous injection. Infusion bottles and bags are one of the commonly used packaging containers for intravenous injection. The liquid medicine for treating diseases is stored in the infusion bottles and bags. The sealing integrity of the infusion bottles and bags is particularly important. Once the sealing surface is poorly welded, the internal liquid medicine may be invaded by external microorganisms, causing the liquid medicine to be contaminated and grow bacteria.

[0003] When pouring liquid medicine into the infusion bottle bag, it needs to be done in the clean area of ​​the pharmaceutical production enterprise. A few seconds after the liquid medicine is filled into the infusion bottle bag, the sealing surface of the infusion bottle bag and the polypropylene combination cover needs to be heated non-contactly under the C+A grade air supply background. After passing through the welding cover heating area, the end faces of the infusion bottle bag and the polypropylene combination cover are melted and sealed into one by gravity pressing.

[0004] The welding cover heating area is composed of 3-5 groups of 14R-19R arc-shaped heating plates made of special aviation steel. When the transformer outputs the control voltage in the corresponding range, the heating plate presents a red spectrum of different strengths, and the surface temperature will rise to 100-400℃. Since the heating plate is an executive component made of special metal, the actual heating efficiency will also decay after long-term use (there may be poor welding on the sealing surface), so it is necessary to monitor the key components of the sealing surface welding of the infusion bottle bag in real time. Therefore, a detection device, method and application of the welding integrity of the sealing surface of the infusion bottle bag are needed to solve the above problems. Summary of the invention
