1. A skin adherable apparatus for delivery of a therapeutic fluid to the body of a patient, comprising:
- a dispensing unit comprising;
a driving mechanism comprising at least a motor, a shaft coupled to said motor, and one or more cogwheel;
a pump driven by said driving mechanism for delivering the therapeutic fluid to the body of the patient;
a flexible reservoir separate from the pump and configured to be compressed by the pump to deliver the therapeutic fluid to the body of the patient from the flexible reservoir;
one or more rails for guiding the pump therealong, the one or more rails being arranged adjacent to the flexible reservoir and extending at least a length along the flexible reservoir; and
wherein the one or more cogwheel is configured to engage the one or more rails, and rotation of the shaft causes rotation of the one or more cogwheel, the one or more cogwheel configured to have teeth that engage teeth disposed along the one or more rails, causing a reusable part, placeable entirely above the reservoir and containing the motor, to translate along a length of a housing of a disposable part in a direction substantially perpendicular to a plane of shaft rotation, such translation pushing down upon the reservoir, causing the therapeutic fluid to be squeezed out from an outlet port and folding the flexible reservoir in a concertina-like fashion.
