First Claim
Patent Images
1. A low profile medication delivery device comprising:
- a chassis having a first dimension X, a second dimension Y orthogonal to the first dimension X, and a third dimension Z orthogonal to both first dimension X and second dimension Y, wherein the first dimension X and the second dimension X form a plane, and wherein the chassis has a first pocket and a second pocket;
an actuator assembly overlaying a plurality of collapsible reservoirs disposed within the first pocket; and
electronics disposed within the second pocket and coupled to the actuator assembly, the actuator assembly being configured to separately control expansion and compression of each collapsible reservoir in response to current being passed through the actuator assembly.
