The invention relates to a portable pump device and a cartridge therefore. The cartridge comprises a first reservoir for a flowable drug provided in combination with a second reservoir comprising a pump liquid, a pump chamber being associated with the first reservoir and adapted to receive the pump liquid in order to expel drug from the first reservoir. In a first aspect, the reservoirs of the system may be provided as a disposable cartridge unit to be combined with a further unit to form an delivery device, the delivery device as a whole comprising the pump means for pumping the pump liquid from the second reservoir to the pump chamber, control means for controlling the action of the pump means, and an energy reservoir for energizing the pump means as well as the control means, however, one or more of these components may be incorporated in the disposable cartridge.

Delivery device and cartridge therefore

A drug delivery device comprising a housing ( ) with a drug container ( ) being provided with delivering means comprising a piston ( ) for expelling a drug ( ) from the drug container ( ). The housing ( ) further comprising a displaceable piston rod ( ) abutting the piston ( ) of the drug container ( ) and rotating means being in engagement with the piston rod ( ), said rotating means being provided with a one-way mechanism. The one-way mechanism comprises a helical spring ( ) wound tightly around an axle ( ), one end of said helical spring ( ) being fixed in relation to the housing ( ), the other end of the helical spring ( ) being in a free state.

Drug delivery device provided with a one-way mechanism

An infuser for infusing a liquid from a reservoir, comprising a durable part (1,2,3) forming a housing and a disposable part (4) containing the liquid reservoir and an energy reservoir for energizing the pumping function. The infuser, further, contains in its disposable part (4) all liquid-contacting elements of the device, and the disposable part (4) and the durable part (1,2,3) are provided with mating coupling means (10,11). A controlling unit in an electronic compartment (3) of the durable part (1,2,3) has a socket (12) into which a plug (13) may be inserted, the plug (13) contains a ROM carrying information defining infusion data. The plug (13) has a transparent sheet (14) covering a display (8) of the durable part when the plug (13) is inserted in the socket (12). The sheet (14) carries a graphic representation of the information in the ROM to be seen in relation to information displayed on the display (8).
