Abstract
A device for dispensing a fluid includes a fixed part to be worn by a user, a fluid connection including a terminal outlet, a needle coupled to the terminal outlet of the fluid connection for dispensing a fluid, and a replaceable part coupled to the fixed part via the fluid connection. The replaceable part includes a reservoir for containing the fluid to be dispensed, and a micro-pump coupled to the reservoir to send the fluid to the fixed part through the fluid connection. An actuator operates the micro-pump. The fixed part includes a pressure-sensor in proximity to the terminal outlet of the fluid connection and is associated with dispensing the fluid from the needle. An electronic control module controls operation of the micro-pump via the pressure-sensor.
