Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
147 words
Finger controlled needle apparatus comprising: housing means shaped to cooperatively receive the finger of a user having at least one needle accommodating aperture therein; at least one hollow needle normally positioned within the housing and adapted to pass through said aperture selectively; fluid reservoir means proximate said housing means; resilient means connecting between, and retaining proximately, said reservoir means and said housing means and biasing said reservoir means within said housing means; means connecting said hollow needle with said reservoir means; means adjacent said reservoir means for projecting said needle through said aperture and forcing fluid from said reservoir through said needle by squeezing said reservoir means between said housing means and said means for projecting; and covering means at least partially retaining said housing means proximate the finger of the user whereby the finger can be flexed to cause ejection of fluid at a desired location.
Claim 2
Dependent Claim
