Claim 1
Independent Claim
240 words
A safely disposable, non-reusable device for aspirating, holding and injecting containable fluid medications, said device comprising in combination: (a) a leading hollow-bore steel needle with a conical needle hub; and (b) a detachable puncture-resistant conical needle cap which slip connects to form an air- and water-tight connection over said conical hollow needle hub and, when reversed, further comprises a plug for a leading end of said device; and (c) a hollow cylindroid consisting of three portions: (i) a leading conical portion with leading slot-like vents, an internal cone which slip connects over said conical needle hub and with internal left-handed threads matching with flanges on a trailing end of said conical needle hub to form a reversible inside Luer-Lok connection, (ii) a cylindric mid-portion housing an elastomeric piston suitable for aspirating or propelling said containable fluid medications when activated by a plunger, (iii) a cylindric trailing portion having an inside narrow annular flange, followed caudally by an outside wide annular flange; and (d) a finger-activated plunger having: (i) a leading end with right-handed threads, (ii) a mid-portion which passes through said elastomeric piston and has holding flanges leading and trailing said elastomeric piston, and (iii) a trailing end with leading means for reversibly engaging said mid-portion of said finger-activated plunger and an expanded trailing means for finger placement; and wherein said conical needle hub has means for releasably engaging said fight-handed threads on said leading end of said finger-activated plunger.

A safely disposable, non-reusable device for aspirating, holding and injecting containable fluid medications, said device comprising in combination: (a) a leading hollow-bore steel needle with a conical needle hub; and (b) a detachable puncture-resistant conical needle cap which slip connects to form an air- and water-tight connection over said conical hollow needle hub and, when reversed, further comprises a plug for a leading end of said device; and (c) a hollow cylindroid consisting of three portions: (i) a leading conical portion with leading slot-like vents, an internal cone which slip connects over said conical needle hub and with internal left-handed threads matching with flanges on a trailing end of said conical needle hub to form a reversible inside Luer-Lok connection, (ii) a cylindric mid-portion housing an elastomeric piston suitable for aspirating or propelling said containable fluid medications when activated by a plunger, (iii) a cylindric trailing portion having an inside narrow annular flange, followed caudally by an outside wide annular flange; and (d) a finger-activated plunger having: (i) a leading end with right-handed threads, (ii) a mid-portion which passes through said elastomeric piston and has holding flanges leading and trailing said elastomeric piston, and (iii) a trailing end with leading means for reversibly engaging said mid-portion of said finger-activated plunger and an expanded trailing means for finger placement; and wherein said conical needle hub has means for releasably engaging said fight-handed threads on said leading end of said finger-activated plunger.
Claim 3
Dependent Claim
30 words
The device, as in claim 1, wherein said hollow cylindroid is supplied without said containable fluid medications and with a breakable portion in said trailing end of said finger-activated plunger.
Claim 4
Dependent Claim

The device, as in claim 1, wherein said hollow cylindroid is supplied filled with said containable fluid medications and with said finger-activated plunger having said trailing end reversibly attachable to a trailing receptacle in said mid-portion by means of right-handed threads.
Claim 5
Dependent Claim
31 words
The device, as in claim 1, wherein a surface of said hollow cylindroid is marked to indicate the volume of said containable fluid medications actually contained before, during and after operation.
