The invention relates to the technical field of
medical instruments, and discloses a preparation method and application of a disposable pump infusion apparatus extension tube. Medical-grade
polyvinyl chloride, a
polyolefin elastomer,
polyethylene glycol terephthalate,
thermoplastic vulcanized rubber, an acetyl
tributyl citrate plasticizer, a
titanium dioxide coloring agent, a
zinc-based stabilizer, a
zinc stearate lubricant, an
antioxidant, an
erucyl amide anti-blocking agent, a
chitosan antibacterial agent and a carbon
fiber reinforcing agent are prepared as main raw materials; preparing a PP filter membrane, a PC joint and a PE protective cap according to the total
mass use ratio of a finished product as key functional components, firstly,
drying, crushing, sieving and disinfecting part of the raw materials, weighing and proportioning in a hundred-grade clean room according to a formula, mixing and plasticizing into a
molten material through high-speed stirring and twin-screw
extrusion,
sizing and cooling after extruding a
pipe blank, and assembling the functional components, so as to obtain a finished product. An on-line
quality monitoring system is installed on the
production line to automatically recognize and isolate unqualified products, finally, finished products are comprehensively detected, and qualified products are sterilized through
ethylene oxide and then packaged in a full-sealed mode.
