Abstract
Abstract A disconnect device for placement in a medical tubing set of the present invention includes a first portion with a first passageway therethrough that has a first valve therein. While the first valve is biased in a normally closed position to close the first passageway, it is operative to an open position. The disconnect device of the invention has a second portion with a second passageway therethrough that has a second valve therein. The second valve is also biased in a normally closed position to close the second passageway and it also is operative to an open position. The second portion is releasably attached to the first portion, connecting the first and second passageways in fluid communication, to overcome the bias of the first valve and the second valve, to open the valves and to allow a fluid flow through the device. When a preselected force, that is, for example, less than a force necessary to physically disrupt a medical access device attached to the tubing set, is applied to the second portion, it is detached from the first portion. With this detachment, the first valve and the second valve are operative to their normally closed positions substantially to stop fluid flow from the fluid reservoir and the medical access device.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
220 words
A disconnect device, comprising: a first housing defining an interior; a first element valve disposed in the first housing; a first plate disposed in the first housing slidingly engaging the first valve element for axial movement with respect to the first valve element; a first spring disposed in the first housing abutting the first plate to bias the first plate against the first valve element and thereby close the first valve element; a first connector operably connected to the first housing; a second housing defining an interior; a second valve element disposed in the second housing; a second plate disposed in the second housing slidingly engaging the second valve element for axial movement with respect to the second valve element; a second spring disposed in the second housing abutting the first plate to bias the second plate against the second valve element and thereby close the second valve element; a second connector operably connected to the second housing whereby when the first connector is connected to the second connector, the first plate is axially moved along the first valve element against the bias of the first spring to thereby open the first valve element and the second plate is axially moved along the second valve element against the bias of the second spring to thereby open the second valve element.
Claim 2
Dependent Claim
220 words
A disconnect device, comprising: a first housing defining an interior; a first element valve disposed in the first housing; a first plate disposed in the first housing slidingly engaging the first valve element for axial movement with respect to the first valve element; a first spring disposed in the first housing abutting the first plate to bias the first plate against the first valve element and thereby close the first valve element; a first connector operably connected to the first housing; a second housing defining an interior; a second valve element disposed in the second housing; a second plate disposed in the second housing slidingly engaging the second valve element for axial movement with respect to the second valve element; a second spring disposed in the second housing abutting the first plate to bias the second plate against the second valve element and thereby close the second valve element; a second connector operably connected to the second housing whereby when the first connector is connected to the second connector, the first plate is axially moved along the first valve element against the bias of the first spring to thereby open the first valve element and the second plate is axially moved along the second valve element against the bias of the second spring to thereby open the second valve element.
Claim 3
Dependent Claim
22 words
The disconnect device of claim 1 wherein the first and second valve elements are each duckbills with at least one closure member.
Claim 4
Dependent Claim
44 words
The disconnect device of claim 2 wherein the first plate includes a first axially extending extension and the second plate includes a second axially extending extension wherein the first extension engages the second extension when the first connector is connected to the second connector.
Claim 5
Dependent Claim
22 words
The disconnect device of claim 3 wherein the first connector is a male member and the second connector is a female member.
Claim 6
Dependent Claim
30 words
The disconnect device of claim 4 further including a fluid tight seal between the male member and the female member when the male member is connected to the female member.
Claim 7
Dependent Claim
143 words
A disconnect device, comprising: a first housing defining an interior; a first valve element disposed in the first housing; a plate disposed in the first housing slidingly engaging the first valve element for axial movement with respect to the first valve element; a spring disposed in the first housing abutting the plate to bias the plate against the first valve element and thereby close the first valve element; a first connector operably connected to the first housing; a second housing defining an interior; a second valve element disposed in the second housing; and a second connector operably connected to the second housing whereby when the first connector is connected to the second connector, the first plate is axially moved along the first valve element against the bias of the spring to thereby open the first valve element and the second valve is opened.
