Apparatus for the reliable filling of the container of an infusion pump
First Claim
1. Apparatus for the reliable filling of at least two containers below the skin surface of an infusion pump comprisinga first and second septa juxtaposed to each other, each having a top and bottom surface, the first and second septa made from a soft material for perforation by a needle,a first and second seal located below the first and second septa respectively, each seal having a top and bottom surface, the seal top surface spaced apart from the bottom surface of each first and second septum respectively,the spaced apart portion between the bottom surface of the first and second septa and the top surface of the first and second seal respectively adapted to receive a medicament from a needle,a first needle stop adjacent and below the bottom surface of the first seal and a second needle stop adjacent and below the bottom surface of the second seal,the first seal having a narrower depth than the second seal, a first needle for the first septum having a lateral filling opening spaced from the first needle tip a distance corresponding to the depth of the first seal,a second needle for the second septum having a lateral filling opening spaced from the second needle tip a distance corresponding to the depth of the second seal so that insertion of either the first or second needle into the wrong septum will result in no flow of medicament.

Abstract
Apparatus for the reliable filling of at least two containers below the skin surface, particularly of an infusion pump, with two septa made from a soft material, so that easy perforation by needles is possible and further seals which are positioned after the septa, at least one space being in each case provided between the seals and the septa connected to the catheters or containers to be filled, in the case of different septa said spaces being at different distances from a needle stop, a corresponding number of needles with lateral openings for filling purposes are provided and the openings for different needles are at different distances (A, B) from the needle tip.
