AMBULATORY INFUSION SYSTEM WITH DETACHABLE DRUG CONTAINER
First Claim
Patent Images
1. A dosing unit for an ambulatory infusion system, the ambulatory infusion system designed for the infusion of a liquid drug into a patient'"'"'s body over an extended time period, the dosing unit comprising:
- an inlet port;
an outlet port, the outlet port being configured to couple to the patient'"'"'s body; and
a pump kernel, the pump kernel comprising a kernel body, the kernel body forming a limiting surface of a stepwise or continuously variable dosing volume;
a control valve, the control valve being configured to couple the variable dosing volume alternatively, in a filling state, to the inlet port for filling or refilling the dosing unit by increasing the dosing volume, or, in a infusing state, to the outlet port for dosing liquid drug out off the dosing unit by decreasing the dosing volume;
wherein the inlet port is configured for being repeatedly manually attached to and detached from an external liquid drug container, thus enabling a repeated sequence of attaching the external liquid drug container to the inlet port, filling the dosing unit with the control valve being in the filling state, detaching the liquid drug container from the inlet port and infusing drug from the dosing unit with the control valve being in the infusing state.

17. A method for storing a drug container comprising:
-
providing; a container storage box having a storage box housing, the container storage box being a self-contained unit, the container storage box comprising a compartment for replaceably receiving a liquid drug container, a temperature control unit housed within the storage box housing, the temperature control unit being designed to vary a temperature of a liquid drug that is stored inside the liquid drug container by actuating an electrically driven heating element and a cooling element to maintain a pre-set temperature within the container storage box; a temperature sensor housed within the storage box housing; the liquid drug; and the liquid drug container storing the liquid drug; and storing the liquid drug container inside the container storage box; storing the container storage box inside a refrigerator; sensing a temperature with the temperature sensor; actuating the electrically driven heating element to maintain the pre-set temperature. - View Dependent Claims (18, 19)
