Gateway System
First Claim
1. A system comprising an inserter device and a gateway for subcutaneous injection of fluid where the gateway comprises a body (1) with at least one through-going opening (6), at least one cannula (3) and a restriction (4) for microorganisms placed at the distal end of the at least one cannula (3) or in the at least one through-going opening (6);
- and which system comprises at least one penetrating member having a proximal end protruding from the lower side of the body (1);
drugs to be injected is delivered to the gateway by a drug delivery device (20) being able to pass the restriction (4) for microorganisms, the gateway is releasably connected to a biasing unit (15) in the inserter device (10, 13) which unit (15) can bring the gateway from a retracted to a forward position when released, characterized in that the gateway comprises a distal surface (1a) corresponding to a proximal surface (1b) integrated with the inserter device.

Abstract
This invention relates to an injection site or gateway or a system comprising such an injection site or gateway. In one form the invention concerns a system comprising an inserter device and a gateway for subcutaneous injection of fluid where comprises a distal surface (1a) corresponding to a proximal surface (1b) integrated with the inserter device. In another form the invention concerns a gateway for subcutaneous injection of fluid, which gateway comprises—a body (1) with at least one through-going opening (6) with an entrance and an outlet, and at least one cannula (3) and having a proximal end protruding from the lower side of the body; —and at the entrance of the through-going opening medication can be injected by a delivery device (20) which delivery device has protruding parts (22) which form an inner opening with a diameter di; wherein the surface of the entrance is shaped in such a way that the cross-section of the top part of entrance, i.e. from the top of the entrance to a position di/3 below the top, do not exceed di.
