Abstract

A parenteral fluid administration set includes a non-vented adapter having a frusto-conically shaped recess therein for removably engaging the tapered tip of a vented container. The adapter includes a bore therethrough communicating with the recess. A drip chamber having an upper portion with a conduit therethrough and a flexible transparent body portion extending downwardly from the upper portion and terminating in a lower end, is provided. The upper portion of the drip chamber is connected to the adapter so that the bore and the conduit are in fluid communication. A flexible tube includes a first end connected to the lower end of the body portion of the drip chamber and a second end. Fluid delivery means for facilitating the delivery of parenteral fluid from the tube to the patient is connected to the second end of the tube.

Claims

1. A non-vented parenteral fluid administration set in combination with a vented container including a housing having a chamber for retaining fluid and a frusto-conically shaped tip extending from said housing having a passageway therethrough communicating with said chamber, comprising:

a non-vented adapter having a frusto-conically shaped recess therein removably engaging the frusto-conically tip of the vented container, said adapter having a bore therethrough communicating with said recess, said bore being positioned to allow fluid communication between said bore and the passageway in the vented container tip;

a drip chamber having an upper portion with a conduit therethrough and a flexible transparent body portion extending downwardly from said upper portion and terminating in a lower end, said upper portion being connected to said adapter so that said bore and said conduit are in fluid communication;

a flexible tube having a first end connected to said lower end of said body portion and a second end; and

fluid delivery means for facilitating the delivery of parenteral fluid from said tube to the patient connected to said second end of said tube.

2. A non-vented parenteral fluid administration set in combination with a vented container including a housing having a chamber for retaining fluid and a frusto-conically shaped tip extending from said housing having a passageway therethrough communicating with said chamber, comprising:

a non-vented adapter having a frusto-conically shaped recess therein removably engaging said frusto-conically shaped tip of said vented container, said adapter having a bore therethrough communicating with said recess, said bore being positioned to allow fluid communication between said bore and the passageway in the vented container tip;

a drip chamber having an upper portion with a conduit therethrough and a flexible transparent body portion extending downwardly from said upper portion and terminating in a lower end, said upper portion being connected directly to said adapter so that said bore and said conduit are in fluid communication;

a flexible tube having a first end connected to said lower end of said body portion and a second end;

fluid delivery means for facilitating the delivery of parenteral fluid from said tube the patient connected to said second end of said tube; and

pinch-type closure means operatively associated with said tube for selectively opening and closing said tube to the passage of fluid.
