Abstract

An IV component has at least one opening and a valve associated with the opening. The valve is normally closed to prevent fluid communication through the opening. A needleless connector can be engaged with a male element of the valve to open the valve and thereby establish a passageway for fluid communication thorough the opening.

Claims

1. A device for holding liquid medicament, comprising:

an IV component having an opening formed therein;

a valve including a valve body operably engaged with the opening and having a first position, wherein a passageway for fluid communication is established through the opening, and a second position, wherein fluid communication through the opening is not permitted, the valve including a male valve element having a skirt disposed in the valve body and an engagement surface extending outwardly beyond the valve body for contacting a spikeless/needleless connector to cause the valve element to reciprocate relative to the IV component;

wherein the valve is biased to the second position and is engageable with the spikeless/needleless connector to establish the first position of the valve.

2. The device of claim 1, wherein the IV component is a component selected from the group of components consisting of:

IV containers, bags, syringes, spikes, fluid lines, drip chambers, filters, Burette chambers, stopcocks, multiport valves, and connector fittings.

3. A valve, comprising:

a hollow body defining a fluid passageway therethrough;

a resilient valve disc positioned in the fluid passageway and biased to a closed configuration, wherein the disc blocks fluid flow through the fluid passageway, the disc being movable to an open configuration, wherein fluid flow is permitted through the fluid passageway; and

a male valve element formed with a skirt and an engagement surface extending outwardly from the fluid passageway for contacting a spikeless/needleless connector, wherein the spikeless/needleless connector can be advanced against the valve element to urge the valve element against the valve disc and thereby move the valve disc to the open configuration.

4. The valve of claim 3, wherein an engagement portion of the valve body is configured as a male luer fitting, and the valve element is reciprocatingly disposed in the engagement portion, and the valve further comprises:

a support element positioned on the valve body on the side of the valve disc opposite the valve element;

a retainer element positioned in the valve body on the opposite side of the disc from the support element, to hold the center of the disc against the support element;

at least one protrusion or groove formed on the body for contacting the valve disc in the open configuration.

5. The valve of claim 4, further comprising a tamper evident cap engaged with the valve.
