Infusion device provided with a water-tight cover
First Claim
1. An infusion device for therapeutic use, comprising a waterproof covering which forms one of a casing, casing part or a container for storing the infusion device and monitoring means for monitoring the water-impermeability of the covering, the monitoring means comprising:
- a) a medium situated in the covering and having at least one physical or chemical parameter which changes in accordance with the impermeability of the covering; and
b) information means which, if said parameter changes, automatically outputs an information signal, at least when the extent of the change signifies a loss of water-impermeability in the covering;
wherein the medium is a gas or vapour which fills the inner space enveloped by the covering; and
wherein the physical or chemical parameter is pressure, and the monitoring means comprises a pressure detector for the pressure prevailing in the inner space or a differential pressure between the inner space and the outer surroundings of the covering.

17. An infusion device comprising a substantially impermeable covering which forms one of a casing of the infusion device, a part of the casing, or a container for storing the infusion device and a monitor for monitoring the impermeability of the covering, the monitor comprising:
-
a medium having at least one physical or chemical parameter which changes in accordance with a change in the impermeability of the covering; and an output which, if said parameter changes, automatically outputs an information signal, at least when the extent of the parameter change signifies a loss of impermeability of the covering, wherein the medium is a gas or vapour which fills an inner space enveloped by the covering, wherein the physical or chemical parameter is pressure, and the monitor comprises a pressure detector for one of the pressure in the inner space or a differential pressure between the inner space and the outer surroundings of the covering.
