Injection Gateway
First Claim
1. Injection gateway comprising:
- a base part secured to the skin of a patient during use,a cannula connected to the base part and inserted into the body of the patient during use,a gate comprising a pierceable septum through which fluid is injectable into the gateway via a needle-based injection device, said gate located at a fixed position in relation to said base part,a fluid passageway operably connecting the gate to the cannula, anda closing mechanism, said closing mechanism having a first position where a needle is insertable into the gateway and insertable into the cannula and a second position where a needle of a needle based injection device is insertable into the gateway to inject fluid into the patient via the cannula but where said needle is prevented from contacting the cannula,wherein the gate is located at the same position in relation to the base part when the closing mechanism is in the first position and when the closing mechanism is in the second position.

Abstract
The current invention relates to an injection gateway (1) comprising a base part (2) which during use is secured to the skin (3) of a patient, a cannula (7) which is connected to the base part and which is inserted into the body of the patient during use, a gate (13) through which fluid is injectable into the gateway via a needle based injection device, and a fluid passageway (12) where fluid injected through the gate is communicated to the cannula. The injection gateway further comprises a closing mechanism (5), said closing mechanism having a first position where a needle inserted into the gateway can be inserted into the cannula and a second position where a needle inserted into the gateway is prevented from coming into contact with the cannula. In this way, the gateway allows the use of typical injection needles without the risk of piercing the cannula or penetrating too deeply into the body of the user.

- 25. A method of using an injection gateway comprising the steps of placing an inserter needle through a cannula of the injection gateway, inserting the inserter needle and cannula beneath the skin of the user, securing the injection gateway to the user, removing the inserter needle, displacing a closing mechanism such that access to the cannula with a needle is prevented, and injecting fluid from a needle based injection device into the user via the injection gateway without further displacement of the closing mechanism.
