Inventor: KUPER TOM GERRIT
IPC: A61J1/05
Filed: 1995-02-27
Abstract: The invention relates to a system for the administration of a medical substance. The system comprises a substance reservoir which has a metering opening which is sealed by a sealing element. A metering line system is detachably connected to a relatively rigid, annular coupling element of the reservoir. The metering line system comprises a flexible channel section with a penetration means located therein. By shortening the channel section, the penetration means can be pushed through the seal of the reservoir after fixing the metering line system to the reservoir. A reliable and relatively simple coupling is obtained by means of a coupling bush which has an annular wall and a base surface with a central opening. The flexible channel section forms one end of the metering line system and extends through the opening of the coupling bush and terminates in a flexible sealing flange. By tightening the coupling bush against the coupling element of the reservoir, the flexible sealing flange is pushed hermetically into contact with the coupling element of the reservoir. The invention further relates to a metering line system and a reservoir for use in a system of this type.
