Abstract

Valve devices are provided for draining fluids from and/or infusing fluids into a patient's body that include a housing including first, second, and third connectors, a primary fluid path communicating between the first and second connectors, and a secondary fluid path communicating from the primary fluid path to the third connector. First and second valve members are movable within the housing between first positions wherein the valve members do not obstruct the primary fluid path and second positions wherein the primary fluid path is at least partially closed. The third connector may be configured to prevent fluid flow therethrough unless a mating connector is fully coupled thereto. The valve members may be selectively closed to isolate portions of the flow path to allow a source of vacuum or fluid coupled to the third connector to aspirate or infuse fluid along portions of the primary fluid path.

First claim

We claim:

1 . A valve device for draining fluids from and/or infusing fluids into a patient's body, comprising:
a housing comprising first, second, and third connectors, and a primary fluid path communicating between the first and second connectors and a secondary fluid path communicating from the primary fluid path to the third connector, wherein the third connector is configured to prevent fluid flow therethrough unless a mating connector is fully coupled thereto; a first valve member movable within the housing between a first position wherein the first valve member does not obstruct the primary fluid path and a second position wherein the primary fluid path is closed to prevent fluid flow through the first connector; and a second valve member movable within the housing between a first position wherein the second valve member does not obstruct the primary fluid path and a second position wherein the primary fluid path is closed to prevent fluid flow through the second connector.

2 . The valve device of claim 1 , wherein the first valve member is biased to the first position.

3 . The valve device of claim 1 , wherein the first valve member is biased to the first position to keep flow through the primary fluid path open when the first valve member is not intentionally directed to the second position.

4 . The valve device of claim 1 , wherein the second valve member is biased to the first position.

5 . The valve device of claim 4 , wherein the first valve member is biased to the first position to keep flow through the primary fluid path open when the first valve member is not intentionally directed to the second position.

6 . The valve device of claim 1 , wherein, with the first valve member in the first position and the second valve member in the second position, an open fluid path is provided between the first and third connectors.

7 . The valve device of claim 1 , wherein, with the first valve member in the second position and the second valve member in the first position, an open fluid path is provided between the second and third connectors.

8 . The valve device of claim 1 , wherein the housing comprises a recess and wherein the third connector is disposed within the recess.

9 . The valve device of claim 1 , wherein the third connector is a luer-activated connector.

10 . The valve device of claim 1 , wherein the first and second valve members are configured to prevent accidental closure or restriction of the primary fluid path.

11 . The valve device of claim 10 , wherein the first valve member is biased to the first position to keep flow through the primary fluid path open when the first valve member is not intentionally directed to the second position.

12 . The valve device of claim 10 , wherein the second valve member is biased to the first position to keep flow through the primary fluid path open when the second valve member is not intentionally directed to the second position.

13 . A system for draining fluids from and/or infusing fluids into a patient's body, comprising:
a valve device comprising a housing comprising first, second, and third connectors, a primary fluid path communicating between the first and second connectors and a secondary fluid path communicating from the primary fluid path to the third connector, wherein the third connector is configured to prevent fluid flow therethrough unless a mating connector is fully coupled thereto, the valve device further comprising first and second valve members for selectively closing flow along the primary fluid path through the first and second connectors, respectively; a tubular member comprising a first end sized for introduction in a patient's body and a second end comprising a tubular member connector configured to couple to the first connector; and a container for storing fluid from the patient's body comprising tubing including a container connector configured to couple to the second connector, thereby providing a fluid path from the tubular member through the primary fluid path and tubing into the container.

14 . The system of claim 13 , further comprising a source of vacuum comprising a vacuum connector configured to couple to the third connector, whereupon the secondary flow path is opened to provide a fluid path between the primary fluid path and the source of vacuum.

15 . The system of claim 14 , wherein the source of vacuum comprises a syringe.

16 . The system of claim 13 , further comprising a source of infusion media configured to couple to the third connector, whereupon the secondary flow path is opened to provide a fluid path between the primary fluid path and the source of infusion media.

17 . The system of claim 16 , wherein the source of infusion media comprises a syringe comprising an infusion media connector configured to couple to the third connector.

18 . A method for draining fluids from and/or infusing fluids into a patient's body, comprising:
providing a valve device comprising first, second, and third connectors, a primary fluid path communicating between the first and second connectors and a secondary fluid path communicating from the primary fluid path to the third connector, wherein the third connector is configured to prevent fluid flow therethrough unless a mating connector is fully coupled thereto, the valve device further comprising first and second valve members for selectively closing flow along the primary fluid path through the first and second connectors, respectively; providing a tubular member comprising a first end introduced in a patient's body and a second end extending from the patient's body; coupling the tubular member second end to the first connector; coupling tubing from a container to the second connector, thereby providing a fluid path from the tubular member through the primary fluid path and tubing into the container; coupling a source of at least one of vacuum and inflation media to the third connector to open the secondary flow path between the primary fluid path and the source; and activating at least one of the first and second valve members to close at least a portion of the primary fluid path.

19 . The method of claim 18 , wherein activating at least one of the first and second valve members comprises activating the second connector to prevent fluid flow to the container, the method further comprising activating the source to one of a) aspirate fluid through the primary fluid path and the tubular member and b) infuse fluid into the primary fluid path and the tubular member.

20 . The method of claim 18 , wherein the first and second valve members are biased to keep the primary fluid path open when the first and second valve members are not activated.
