Infuser
First Claim
1. An infusion system comprising:
- a housing for receiving a replaceable unit; and
a self-contained, replaceable unit having;
a reservoir containing a liquid to be infused, an infusion line communicating with said reservoir, a pump for pumping liquid from said reservoir out through said infusion line, an energy reservoir for operating said pump, and a memory for storing a value representing the amount of liquid remaining in said reservoir; and
wherein said housing and replaceable unit further include a mating coupling for releasably securing said replaceable unit within said housing so as to allow said replaceable unit to be readily removed and replaced when desired, and wherein a portion of said infusion line extends to the exterior of said housing.

Abstract
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).
