Hydraulic Component Hygienic Treatment via Permeable Port Covers

The patent applies preliminary sterilization treatment to the pipes during the extrusion process itself, before they are subjected to storage and installation. By incorporating sterilizing agents into the plastic material during extrusion, the pipes are pre-sterilized and can then be stored and handled in non-protected environments without immediate contamination, resolving the contradiction between ease of distribution and hygienic characteristics

The patent changes the chemical parameters of the pipe material by incorporating sterilizing agents (such as silver ions, zinc ions, or other biocidal substances) into the plastic matrix during extrusion. This parameter change gives the pipes inherent antimicrobial properties that prevent contamination during storage and installation, allowing them to maintain hygienic characteristics even when exposed to environmental factors

The patent performs sterilization during the extrusion process itself, which occurs before any autoclave cross-linking treatment. This preliminary sterilization ensures that the pipes are already sterile before entering the autoclave, and the cross-linking process then maintains rather than compromises these hygienic characteristics, resolving the contradiction between improving mechanical strength and maintaining hygiene

The patent merges the sterilization function with the extrusion manufacturing process by incorporating sterilizing agents directly into the plastic material during extrusion. This combination ensures that sterilization and cross-linking are coordinated processes, where the sterilization occurs first and the cross-linking subsequently preserves the hygienic characteristics while providing the desired mechanical strength
