Abstract:
1. A medicinal vial assembly including means for preventing vacuum-lock when withdrawing medicinal fluid therefrom via a hypodermic needle, comprising in operative combination: a) a medicinal vial including a generally tubular side-wall, a bottom wall spanning a first end, and a neck having an opening terminating in a lip at an opposed, second end, said vial defining a volume for carrying a quantity of medicinal fluid in sanitary condition; b) an elastomeric bladder disposed in said vial volume permitting compensation for withdrawal of medicinal fluid from said vial; c) a vial stopper configured to fit tightly in said vial neck and seal against loss of medicinal fluid from said vial volume, said stopper having an upper flattened flange member and a body portion having a vertical axis and extending downwardly from one side of said flange member, said stopper body portion having an outer diameter sized to sealingly fit said vial neck opening and terminating in a plurality of depending stopper fingers, said stopper fingers having an annular thickness substantially less than the diameter of said stopper body and disposed around and spaced from said vertical axis of said body portion to form an open-bottom cavity in which said hypodermic needle can freely access said medicinal fluid; and d) said stopper fingers having a length longer than a suitable hypodermic needle inserted in said vial to withdraw said medicinal fluid, whereby said stopper fingers prevent needle puncture of said bladder by shielding said bladder from contact with said needle as medicinal fluid is withdrawn from said vial.
