Patent Images
1. A device comprising:
- a reservoir to accept a flow of a medicine at a pre-defined rate;
a pump to expel up to a pre-designated volume of said medicine from said reservoir;
a volume setting means to accept said pre-designated volume setting for said expelling from among a plurality of volume settings; and
an outlet to direct a flow of said medicine from said reservoir to a channel to a body at said pre-defined rate when said reservoir is full and at a volume of up to said pre-designated volume when said pump is activated.

8. A method comprising:
-
accepting a setting of a maximum volume of medicine to be expelled into an exit channel from a reservoir upon activation of a volume delivery means, said maximum volume from among plurality of volume settings; selecting a flow rate of said medicine to flow through said exit channel over a pre-defined period, said flow rate to include said volume expelled by said pump during said period. - View Dependent Claims (9, 10, 11)

12. A method comprising:
-
accepting a setting for limiting of a reduction in a volume of a drug reservoir that is achieved upon activation of a pressure means upon said reservoir; defining a rate of a flow of said drug to said reservoir, and defining said rate of a rate of a flow of said drug from said reservoir when said reservoir is full to be equal to said rate of said flow of said drug to said reservoir. - View Dependent Claims (13)

14. A device comprising
a reservoir suitable to receive a flow of a drug at a pre-designated rate; -
a manually operated pump suitable to compress said reservoir an outlet having a pressure-triggered valve suitable to open upon a manual activation of said pump; and a variable restricting means to limit a volume of said drug expelled from said reservoir upon an activation of said pump, said volume limited to a pre-set volume.
