  • Patent number: 7147623
    Abstract: The invention relates to a medication infusion set of the type having a flexible cannula adapted for subcutaneous placement, in combination with an insertion, or puncturing, device comprising an insertion needle extending through the cannula and beyond the outer tip thereof, the insertion device further comprising a shield adapted to cover the insertion needle when the latter is withdrawn from the cannula. More specifically, the invention provides a fully integrated shield member having a position in which it covers the cannula and the needle when the insertion device is connected to the housing, a position allowing the cannula to be inserted when the insertion device is connected to the housing, and a position in which the shield covers the needle and the outer tip thereof when the insertion device has been removed from the housing. By this arrangement the need for a separate cover to protect the needle prior to use can be dispensed with.
