Abstract:
An apparatus (120) useful for, among other things, subcutaneous drug delivery includes a housing (124), a fluid reservoir (154) disposed within the housing for storing the fluid, a pump or pressurized chamber for pressurizing a driving gas and exerting a force on the fluid reservoir to expel the fluid reservoir's contents, and a needle (150) or absorbent pad fluidically communicating with the reservoir. The apparatus may further include a pump activation mechanism such as a button and an electrical circuit such that pushing the button activates a circuit and connects a battery (138) to a pump (126), and a pump control mechanism such as electrical circuitry to control the voltage gradient to a pump to control fluid delivery.
