Stainless Steel Venous Indwelling Needle Tube For Medicine Administration ISO9626 SUS304
Stainless Steel Venous Indwelling Needle Tube for Medicine Administration ISO9626 SUS304
An indwelling needle tube is a type of needle tubes that remains inserted in a patient's body, which can be temporarily or permanently, for various medical purposes, such as medicine administration, fluid drainage, or monitoring. The indwelling needle that is implanted in veins for a long time can avoid repeated punctures. It's also known as an indwelling catheter or a permcath. It’s the core cannula of a venous indwelling needle (IV catheter), designed for safe insertion into peripheral veins for infusion or blood sampling for multiple times over a period (typically 72-96 hours). The indwelling needle tubes are one of our company’s high-volume manufactured medical needle tubes. We have the most advanced auto machines for needle grinding and mature technical conditions. And our needle tubes are mainly made from medical grade stainless steel 304 grade. If clients have special requirements for needle tube sizes and needle points, we can design the medical needle tubes basing on clients’ drawings and samples.
