Abstract

A flexible container for medical fluids having a combined fill and administration port of at least two parts so that the container can be filled through the first part of the port, the second part thereafter being inserted into the first part to seal the container, and a reinforced hanger portion to prevent uneven collapse of the top of the container and thereby permit a well defined meniscus for improved readability of the fluid level within the container.

Claims

1. A flexible, collapsible container for medical fluids made of a chemically inert plastic material, said container comprising:

a pair of opposed walls sealed along the entire perimeter thereof to form said container, a reinforced hanger portion at one end of said container including a stiff card encapsulated within an envelope formed by said sealed opposed walls, said reinforced hanger portion minimizing distortion of said container so that the meniscus formed by said fluid therein can be easily read and the amount of fluid being administered can be accurately determined, a combined fill and administration port disposed on the end of said container opposite said hanger portion and including a fill port formed by a semi-rigid tubular portion having open ends, said tubular portion being disposed between said opposed walls of said container and sealed therein to provide communication into the interior of said container, and an annular flange perpendicular to the axis of said tubular portion and extending from the end of said tubular portion spaced away from said container, said administration port including a close fitting tubular section inserted into said tubular portion of said fill port and having a passageway therethrough with an open end spaced away from said container, the other end of said passageway being closed by a puncturable diaphragm, the end of said tubular section of said administration port spaced away from said container having an annular flange also perpendicular to the axis of said tubular portion and said tubular section and extending therefrom, said flange of said tubular section being coextensive with said flange of said fill port; and

a cover for sealing said combined fill and administration port, said cover including a body having an annular flange extending therefrom coextensive with said flanges of said fill and administration ports, the respective flanges of said fill port, administration port and cover being sealed together to seal said container, said cover including a weakening ring formed in the inner surface of said cover radially inwardly of said cover flange and adjacent said administration port, and an integral handle extending perpendicularly away from the outer surface of said cover immediately opposite said weakening ring, which handle and weakening ring facilitate removal of said cover.

2. The flexible, collapsible container of claim 1 including reinforcing ribs formed in the reinforced hanger portion and arranged transverse to the longitudinal axis of the container.
