Abstract

A filling and metering assembly designed to fill syringes accurately by a sightless person wherein the assembly includes an elongated base having an open side exposing an interior surface which is specifically configured to removably position and hold a syringe and a medicine container therein. Another structure associated with the subject assembly includes an indicator structure associated therewith which is adapted to produce an audible sound capable of being heard by the sightless user of the assembly in the determination of an accurate and desired amount of medicine being passed from the medicine container to the interior of the syringe.

Claims

1. A syringe filling assembly designed to allow metering of a liquid into a syringe by a sightless person, said assembly comprising:

a) an elongate base having an open side extending along a majority of the length thereof and said base terminating in opposite ends,

b) said base including an interior surface extending along the length of said base and exposed in accessible communication with said open side,

c) said inner surface of said base comprising a plurality of recesses integrally formed therein and configured to receive an outer surface portion of the syringe and medicine container therein,

d) metering means movably mounted on said base and structured and disposed for regulating a quantity of liquid passing into the syringe from the medicine container,

e) said metering means structured and disposed to be selectively movable between an inwardly extended position and an outwardly protracted position relative to both said base and the syringe when mounted on said base,

f) said metering means comprising an elongated shaft movably connected to a first of said opposite ends o said base and movable through said first end towards and away from the syringe,

g) said first end including an open construction defined by a first collar configured in surrounding relation to at least a portion of said metering means,

h) said first collar comprising an internally threaded construction integrally formed along said interior surface thereof;

said elongated shaft comprising an externally threaded construction disposed in movable, mating, threaded engagement with said interior surface of said first collar,

i) an indicator means structured and disposed to engage a plurality of threads of said externally threaded construction, said indicator means structured and disposed to produce a plurality of successive sounds upon engagement with a plurality of successive threads of said externally threaded construction of said elongated shaft, and

j) said indicator means and said threaded construction of said elongated shaft being cooperatively calibrated relative to one another so as to indicate one unit volume of medicine being dispensed per one of the plurality of successive sounds being produced by said indicator means.

2. An assembly as in Claim 1 wherein said opposite ends of said base comprise a second end oppositely disposed to said first end and adapted to removably support the medicine container therein.

3. An assembly as in Claim 2 wherein said second end has an open construction structure and disposed to allow passage of the medicine container therein and into engagement with the syringe.

4. An assembly as in claim 3 wherein said open construction of said second end is defined by a second collar configured and dimensioned for surrounding engagement with the medicine container.

5. An assembly as in claim 4 further comprising retaining means mounted on said second collar and disposable into engaging relation with the medicine container and adapted for removably retaining the medicine container within said second collar.
