ORAL MEDICINE DISPENSING SYSTEM

摘要

A liquid dispensing system for oral administration comprises a dispenser and cartridges from which medicine is dispensed. Each cartridge includes a hollow shell with a septum at one end, a piston at the other end, and the medicine in a cavity between the septum and the piston. The dispenser includes receiver in which a cartridge is received, a plunger that can slide relative to the receiver and that has a plunging head that can drive the piston, and a barrel in which the cartridge, receiver and plunger can be received, at least partly. Once a cartridge has been inserted into the receiver, the receiver and cartridge are inserted into the barrel and a piercing head ruptures the septum. The plunger is pushed to drive the piston and the medicine is dispensed by the piston, through a discharge passage of the barrel.

a hollow, elongate shell that has a longitudinal axis and that defines an internal cavity and that is closed at one end with a septum, at least part of said septum being thin enough to rupture when pricked with a sharp object;a piston that is disposed inside the shell and that can slide axially inside the cavity, while sealing against the inside of the shell; anda liquid medicine, which is held inside the cavity between the closed end and the piston; and a dispenser that includes:
a body defining a receiving formation in which at least the closed end of the shell of the cartridge is receivable;a sharp protuberance disposed in the receiving formation and configured to rupture the septum if the cartridge is moved far enough in the axial direction; anda plunger that is displaceable in the axial direction towards the protuberance wherein said dispenser includes a receiver defining a recess in which the cartridge is receivable, at least in part, said plunger being attachable to the receiver, to slide relative to the receiver and cartridge shell in the axial direction.
