Abstract
A fluid injection device having a body contacting an injection site (SI); fluid reservoirs (210); an injection needle (120) that injects the contents of the reservoir(s) (210); and a respective priming needle (125) associated with each reservoir (210) for penetrating into the reservoir (210) before dispensing the fluid. Each reservoir (210) includes a tube (145) connected at one end to a priming needle (125), and at the other end to the injection needle. The device includes a reservoir selector for selecting one or more reservoirs (210), the contents of which are dispensed during the next actuation. The selector has a rotary member (132, 135) with a cam (1320, 1350) to co-operate with the tubes (145) so as to open or close the flow of fluid through each tube (145).

1-16. (canceled)
A fluid injection device comprising:
- a body for coming into contact with an injection site (SI);
- at least three fluid reservoirs;
- an injection needle for penetrating into said injection site (SI) so as to inject therein the contents of one or more reservoir(s);
- and a respective priming needle associated with each reservoir for penetrating into said reservoir before dispensing the fluid, each reservoir including a tube that is connected at one end to its priming needle, and at the other end to said injection needle;
- said device being characterized in that it further comprises reservoir selector means for selecting one or more reservoirs, the contents of which are to be dispensed during the next actuation, said selector means comprising a rotary member that is provided with cam means that are adapted to co-operate with the tubes of the reservoirs so as to open or close the flow of fluid through each tube, the flow of fluid in a tube being closed off by said cam means pinching/flattening said tube(s), thereby selecting the reservoir(s) to be dispensed during actuation.
