Claim 3

The parenteral fluid administration set of Claim l wherein said tube has a substantially circularly-shaped cross section.

Claim 4

The parenteral fluid administration set of Claim l wherein said non-vented adapter and said upper portion are integrally formed.

Claim 5

The parenteral fluid administration set of Claim l wherein said fluid delivery means includes a male luer adapter having a tapered tip for removably engaging a hypodermic needle assembly and establishing fluid communication between the needle assembly and said tube.

Claim 6

The parenteral fluid administration set of Claim 4 wherein said fluid delivery means includes a removable shield for protecting said tapered tip of said male luer adapter.

Claim 7

The parenteral fluid administration set of Claim 4 further including a hypodermic needle assembly having hub means engaged with said male luer adapter, and a needle cannula projecting outwardly from said hub means.

Claim 8

The parenteral fluid administration set of Claim 6 further including a needle shield removably engaging said hub means for protecting said needle cannula before use.

Claim 9

The parenteral fluid administration set of Claim l wherein said fluid delivery means includes a needle cannula having a lumen therethrough in fluid communication with said tube.

Claim 10

The parenteral fluid administration set of Claim l further including pinch-type closure means operatively associated with said tube for selec­tively opening and closing said tube to the passage of fluid.

Claim 11

l0. The parenteral fluid administration set of Claim l further including flow control means operatively associated with said tube for varying the flow of fluid through said tube.

Claim 12

The parenteral fluid administration set of Claim l0 where said flow control means includes a conventional roller clamp.

Claim 13

The parenteral fluid administration set of Claim l0 further including access means connected to said tube between said drip chamber and said flow control means for allowing introduction of additional parenteral fluid into said tube.

Claim 14

The parenteral fluid administration set of Claim l2 wherein said access means includes a pierceable septum adapted to be pierced by a sharpened cannula to allow fluid to enter said tube through the sharpened cannula, said septum further adapted to seal itself upon the removal of the sharpened cannula therefrom.

Claim 15

The parenteral fluid administration set of Claim l2 further including one-way valve means operatively associated with said tube between said drip chamber and said access means for substantial­ly preventing flow of parenteral fluid in a direction from said access means toward said drip chamber while allowing fluid flow from said drip chamber toward said access means.

Claim 16

A parenteral fluid administration set comprising: a non-vented adapter having a frusto-conically shaped recess therein adapted to removably engage the tapered tip of a vented container, said adapter having a bore therethrough communicating with said recess; 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.

Claim 17

A parenteral fluid administration set comprising: a non-vented adapter having a frusto-conically shaped recess therein adapted to removably engage the tapered tip of a vented container, said adapter having a bore therethrough communicating with said recess; 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.

Claim 18

A parenteral fluid administration set for use with a variable-volume vented container includng a housing having a chamber for retaining fluid and a tip extending from the housing having a passageway therethrough communicating with said chamber, the tip being frusto-conically shaped having a smaller outside diameter at the distal end of the tip than at the proximal end of the tip comprising: a non-vented adapter having a frusto-conically shaped recess therein adapted to removably engage the tapered 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 when the tip engages said recess; 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 to 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.

Claim 19

A parenteral fluid administration set for use with a variable-volume vented container includng a housing having a chamber for retaining fluid and a tip extending from the housing having a passageway therethrough communicating with said chamber, the tip being frusto-conically shaped having a smaller outside diameter at the distal end of the tip than at the proximal end of the tip comprising: a non-vented adapter having a frusto-conically shaped recess therein adapted to removably engage the tapered 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 when the tip engages said recess; 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 to 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.

Claim 20

The parenteral fluid administration set of one of Claims l-l6 wherein said fluid delivery means in­cludes a removable shield for protecting said tapered tip of said male luer adapter.
