IV sets with needleless spikeless fittings and valves
First Claim
Patent Images
1. A valve, comprising:
- a valve body configured as a Luer fitting;
a resilient valve member defining an outer periphery that is uninterrupted within the periphery disposed in the valve body and biased to a first configuration, wherein a passageway for fluid communication is not established through the valve body, the member being movable to a second configuration, wherein fluid communication through the valve body is permitted; and
a male valve element disposed in the valve body and defining an engagement surface extending outwardly beyond the valve body for contacting a spikeless/needleless connector to cause the valve element to move against the valve member and move the valve member to the second configuration.

Abstract
An IV set includes a drip chamber having a top end and a bottom end. A spikeless connector covers the top end, and an IV tube is connected to the bottom end of the drip chamber. The end of the IV tube opposite the drip chamber is engaged with a needleless/spikeless connector. Thereby, a needleless/spikeless IV set is rendered. A reflux valve including a deformable valve member and reciprocating valve element is also disclosed for use in conjunction with the needleless/spikeless IV connectors.

15. An IV disposable system that reseals when disconnected, comprising:
-
a distal end configured as a Luer fitting with a resilient valve member defining an outer periphery that is uninterrupted within the periphery, disposed in the distal end and biased to a first a first configuration, wherein a passageway for fluid communication is not established through the system, the member being movable to a second configuration, wherein fluid communication is permitted; an intermediate structure; and a proximal end configured as a Luer fitting with a resilient valve member defining an outer periphery that is uninterrupted within the periphery, disposed in the proximal end and biased to a first a first configuration, wherein a passageway for fluid communication is not established through the system, the member being movable to a second configuration, wherein fluid communication is permitted, the intermediate structure interconnecting the distal and proximal ends. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
