1. A portable ambulatory therapeutic fluid delivery device for delivering a therapeutic fluid in bolus doses into a body of a patient, the device comprising:
- at least one housing connectable to a cannula;
a counter for displaying a value representative of an amount of therapeutic fluid delivered by operation of the device, the counter comprising a mechanically detachable counter housing configured for attaching and detaching from the at least one housing; and
a cradle securable to the patient'"'"'s skin, wherein the cradle is configured for releasably receiving the at least one housing enabling connection and disconnection of the at least one housing therefrom;
the at least one housing including;
a reservoir for storing a therapeutic fluid;
a pump for delivering one or more bolus doses of the therapeutic fluid from the reservoir to the body of the patient through the cannula, wherein the pump is configured for non-electrical operation; and
an actuator for transferring manual power provided by the patient for operating the pump;
wherein displacement of the pump is limited for delivery, of a bolus dose corresponding to a pre-determined amount.

Abstract
Disclosed is an ambulatory therapeutic fluid delivery device (10). The device includes at least one housing (200) connectable to a cannula (250), the at least one housing retaining a reservoir (220) to hold the therapeutic fluid. The device also includes a mechanically powered pumping mechanism (150) to cause delivery of at least some of the fluid from the reservoir, and a power-transfer mechanism to transfer manually-delivered power provided by a user to mechanically actuate the pumping mechanism.
