Abstract

Some embodiments of a wearable, disposable medicine dispensing device may include a piston rod that is advanced to dispense medicine from the device. A rotational motor may be coupled to a drive mechanism so as to carry out a certain number of revolutions and thereby displace the piston rod by a desired distance. Such a device can be used in a method of dispensing liquid medicine.

Claims

1. An actuator comprising:

a rotational motor;

one or more elongate, flexible elements such as a string, a filament, a strip, a ribbon and combinations thereof, said one or more elements being attached to said motor for rotation thereby and to a displaceable body, such that rotation of said motor twists said one or more elements and shortens the overall length thereof so that said displaceable body is displaced by the shortened element or elements.
