Infusion set is a device for inserting a cannula into tissue, including a cannula, a protective element which can accommodate said cannula, an operating element for moving the cannula out of the protective element, and a holder fixedly connected to the cannula. The invention encompasses a system for connecting a liquid supply to the cannula. Contract Packaging organizations providing infusion sets ensure that the device has these features: The tubing and chamber must be non-toxic, non-irritant material; The flow regulator and piercing spike must be made from medical friendly ABS compound to offer superior performance; The protective cap must offer due protection of piercing spike and better penetration of EO for sterilization; The flow regulator should allow to adjust the flow of the infusion solution between Zero and the maximum smoothly. Nowadays, infusion sets are available in various tubing, cannula, and needle sizes. Pharma Packaging service providers today offer infusion sets with various available options such as: With or Without Airvent; With or Without Needle; With or Without "Y" Connection; With or Without Luer Lock; With or Without Dial type Flow Regulator; Latex or Latex Free; PVC or PVC Free; Available with 1.2 or 0.2 Micron In-Line Filter; Available with Needle-Free Connectors; Available with DEHP Free Material; Available with Check – Valve; Tube Length : 150cms, 180cms, 200cms; Size : Adult, Child.
