Method and apparatus for adjusting the contents of a needle-less injector
First Claim
1. An apparatus for adjusting contents of a needle-less injector, comprising:
- an adjustment switch to adjust said contents of said needle-less injector;
a driver to force a volume of said contents of said needle-less injector out of said needle-less injector through an orifice; and
a transecting member attached to said adjustment switch, to provide mechanical interaction between said adjustment switch and said driver, wherein displacement of said adjustment switch in the direction of a dispensing end of said needle-less injector causes said driver to move toward said dispensing end of said needle-less injector.

Abstract
A method and apparatus for adjusting the contents of a needle-less injector that contains an injectable product are described. A needle-less injector includes an adjustment switch in mechanical contact with the driver of a needle-less injector. A user may displace the adjustment switch to expel air or gas contained in the product section of the needle-less injector prior to administration of a needle-less injection with the same. The adjustment switch may alternatively or additionally be used to expel at least a portion of the injectable product contained in the needle-less injector to reduce the volume of the product to be injected with the needle-less injector.

24. A method of administering a needle-less injection with an adjusted volume of an injectable product, comprising:
-
providing a needle-less injector, comprising an adjustment switch to adjust said contents of said needle-less injector, a driver to force a volume of said contents of said needle-less injector out of said needle-less injector through an orifice, and a transecting member attached to said adjustment switch, to provide mechanical interaction between said adjustment switch and said driver, wherein displacement of said adjustment switch in the direction of a dispensing end of said needle-less injector causes said driver to move toward said dispensing end of said needle-less injector; and
displacing said driver toward said dispensing end to expel a portion of said injectable product leaving said adjusted volume within said needle-less injector; and
administering an injection with said needle-less injector. - View Dependent Claims (25, 26, 27, 28)
