Abstract

In an intravenous fluid administration assembly, there is provided a suspended, fluid holding container having a stopper closing off its mouth, a conduit having a hollow spike inserted into the stopper for gravity flow delivery of fluid from the container to the conduit, and a clamp for preventing the unintentional separation of the spike from the stopper. The clamp has a first portion having an opening through which the container's neck extends downwardly and a second portion having an opening through which the spike extends upwardly. The first portion seats on an abutment on the container's neck and the second portion seats under a flange extending outwardly from the spike. First ends of the first and second portions are connected by a third portion of the clamp and the openings in the first and second portions extend to those portions' other free ends. The clamp is slid over the container and spike, after insertion of the spike into the stopper, by placement of the free end and opening of the first portion around the container's neck and over the abutment and free end and opening of the second portion around the conduit and below the flange extending outwardly therefrom.

Claims1

Dependent claims

In a fluid assembly including a container suspended in an inverted position, said container having a relatively narrow neck defining a discharge opening from said container, said neck having an enlarged diameter portion adjacent the end thereof, a stopper disposed in said discharge opening and a fluid delivery conduit terminating in a spike, said spike being inserted sufficiently into said stopper to communicate with the interior of said container, said spike having an enlarged flange portion exterior of said container, the improvement comprising:

a generally U-shaped clamp for preventing the unintended separation of the spike from the stopper, said clamp having a pair of flat, substantially parallel leg portions, each leg portion terminating in a free end;
a spike-receiving slot defined in one of said leg portions and extending through the free end thereof, said spike-receiving slot having a width less than the width of said flange to prevent said flange from passing therethrough;
the other of said leg portions defining a neck-receiving aperture therein and a slot communicating between said aperture and the free end of said other leg portion, said neck-receiving aperture being smaller than said enlarged diameter portion of the container neck to prevent withdrawal of the neck through said aperture, said communicating slot having a width smaller than the width of said container neck and said other leg portion being sufficiently resilient to permit temporary spreading of said communicating slot to receive said container neck being disposed in neck-receiving aperture of said other leg portion, whereby said enlarged diameter neck portion and said spike flange are captured between said leg portions of said clamp, said clamp thereby preventing unintended separation of said spike from said stopper.
