Claims14
A drug pump comprising:
- multiple expandable and contractable chambers, including at least a first chamber, a second chamber and a third chamber, wherein the first chamber and the second chamber are positioned so that expansion of the first chamber causes contraction of the second chamber, and contraction of the first chamber causes expansion of the second chamber;
- wherein the second chamber is structured to connect to a reservoir for retaining a drug medium;
- wherein the third chamber is formed with the second chamber and includes (i) an intake for the drug medium, and (ii) an outlet to expel the drug medium;
