50. A disposable, wearable medicine dispensing device comprising
a housing; -
means for attaching said housing to the skin of a user of said device, a medicine container disposed in the housing;
a flexible piston rod having an outer thread pattern on at least a portion thereof, the piston rod being movable in a forward longitudinal direction to force medicine from the medicine container;
a ratchet wheel having an inner thread pattern on a central aperture to mate with the outer thread pattern of the flexible piston rod such that rotation of said ratchet wheel in a forward rotational direction displaces the flexible piston rod in the forward longitudinal direction;
a pivotable body disposed in the housing and adjustable between a forward position and a reset position, wherein adjustment of the pivotable body from the reset position to the forward position causes the ratchet wheel to rotate in said forward rotational direction;
a spring device to bias said pivotable body toward the forward position; and
an actuation system to controllably adjust the pivotable body toward the reset position, the actuation system comprising;
a thread member coupled to the pivotable body, and a battery powered actuator coupled to the thread member so as to apply a tension force to the thread and thereby adjust the pivotable body. - View Dependent Claims (51, 52, 53, 54, 55, 56, 57)
