Abstract
A fluid injection device having a body for coming into contact with an injection site (SI); at least two fluid reservoirs (210); and an injection needle (120) for penetrating into the injection site (SI) so as to inject therein the contents of one or more reservoir(s) (210); the device further has a single rotary actuator (130) that, when it turns in a first direction of rotation, activates the selection of the reservoir(s) (210) to be dispensed, and that, when it turns in the opposite direction, actuates a dispenser system, in particular a peristaltic pump (150).
Claims19
A fluid injection device comprising:
- a body for coming into contact with an injection site;
- at least two fluid reservoirs containing fluids;
- and an injection needle for penetrating into said injection site so as to inject therein fluid contained in one or more of the at least two fluid reservoirs;
- said fluid injection device further comprises a single rotary actuator that, when turning in a first direction of rotation, activates the selection of the fluid reservoir(s) to be dispensed, and that, when turning in the opposite direction, actuates a dispenser system, said single rotary actuator including a central pin that extends through an oblong opening of the body, thereby forming a floating cog.
