A portal access device that is adapted to provide long term access to a port implanted in a patient has two major components, an infuser assembly and a safety needle insertion device. The infuser assembly has an infuser housing that can be configured into a specific shape, for example a dome. A blunt cannula is attached to and extends downwardly from the underside of the infuser housing. Also connected to the infuser housing, preferably at a side thereof, is a tubing or catheter. The safety needle inserter assembly has a base having a proximal portion that is configured to form fit over the infuser housing. At the distal portion of the base uprights are provided so that a second end of an arm, to which first end a needle or a sharp cannula is connected, may be movably and hingedly connected to the base. The sharp cannula extends from the underside of the proximal end of the arm and passes through the base by way of a bore formed at the proximal portion of the base. The bore is defined between an opening at the underside of the base and an opening at the upper surface of the base. Locking mechanisms are provided at the base uprights and the distal end of the arm so that when the arm is moved away from the base, and as the distal end of the arm pivots about the uprights, the respective locking mechanisms provided at the arm and the base would coact to lock the arm in place, to thereby maintain the tip of the needle within the bore formed in the base. To use, the safety needle inserter is placed over the infuser assembly, with the sharp cannula extending through the infuser housing and axially mating with the blunt cannula of the infuser assembly, but with the tip of the sharp cannula protruding beyond the tip of the blunt cannula. The combined needle inserter/infuser assembly is pressed down onto the skin surface of the patient so that the combination sharp/blunt cannulas penetrate the patient and puncture the self-sealing septum of a portal reservoir implanted in the patient. Once the safety needle inserter is removed from the infuser assembly, with the infuser housing septum being self-sealing, a closed fluid communication path is established between the portal reservoir and a fluid store that may be connected to the catheter of the infuser assembly. Long term access of the implanted portal reservoir is thereby achieved.

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.
