Abstract

The multi-ported valve assembly includes a valve body having a plurality of individual ports disposed in a common plane and a common port having its axis disposed perpendicularly to the common plane of the individual ports. The valve assembly includes a selector means having a body portion designed to engage the valve body and provide selective communication between one of the individual ports and the common port. The selector means includes a handle to facilitate rotation thereof and selection of a desired fluid flow passageway as well as indicator means to indicate direction of fluid flow. Also provided are sealing means to prevent external leakage during use and suitable connecting or coupling means to provide connection especially in devices and apparatus used in ophthalmic surgical procedures.

Claims

1. A multi-ported valve assembly comprising:

a) a hollow cylindrical first valve body having a generally cylindrical chamber therein, said chamber forming a first opening in said valve body, said valve body further comprising;

i) a plurality of first ports extending outwardly from said valve body, and being disposed in a common plane; and

ii) a second port extending outwardly from said valve body, the axis of said second port being substantially perpendicular to said common plane;

b) a selector comprising a generally cylindrical body having an axis aligned with said second port axis, said generally cylindrical body having a first portion positioned in said generally cylindrical chamber and a second portion disposed outside of said cylindrical chamber, said second portion including a handle extending outwardly for rotating said cylindrical body, a passageway internal to said first portion for providing communication between said second port and one of said first ports or a shut-off position when said handle is rotated about said axis of said generally cylindrical body to a predetermined position, said generally cylindrical body including a second opening in said second portion and part of said first portion;

c) a recess on an inner wall of said chamber of said valve body and a protrusion on an outer wall of said first portion of said cylindrical body, said protrusion engaging said recess to prevent external leakage of fluid flowing through said valve and to maintain relative positions of said valve body and said selector, said recess positioned between said common plane and said first opening of said valve body; and

d) indicator means for indicating direction of a fluid flowing through said valve.

2. The valve assembly of claim 1 wherein said indicator means further comprises adjustable indicia means to permit indication of direction of fluid flow in one of said first ports.

3. The valve assembly of claim 1 wherein said handle further includes an arrow-shaped portion for indicating direction of fluid flow in one of said first ports.

4. The valve assembly of claim 2 wherein said adjustable indicia means includes an arrow-shaped clip removably attached to a portion of said handle to indicate direction of fluid flow in one of said first ports.

5. The valve assembly of claim 1 wherein each of said first ports further comprises a hollow elongated member having a tapered inner diameter and a coupling means on the distal end thereof.

6. The valve assembly of claim 1 wherein said second port comprises a hollow elongated member and means to couple said member to an ophthalmic surgical device.

7. The valve assembly of claim 6 wherein said means to couple said member further comprises a generally cylindrical housing surrounding at least a portion of said hollow elongate member and having threads therein for facilitating coupling to an ophthalmic surgical device.

8. The valve assembly of claim 1 further comprising a generally cylindrical housing surrounding at least a portion of said second port and having internal threads thereon for facilitating coupling said second port to an ophthalmic surgical device.

9. The valve assembly of claim 1 wherein said second port is removably connected to a source of vacuum and each of said first ports are removably connected to a surgical instrument requiring a source of vacuum for operation.

10. The valve assembly of claim 1 wherein said second port is removably connected to a source of irrigation fluid and each of said first ports is removably connected to a surgical instrument requiring a source of irrigation fluid for operation.

11. The valve assembly of claim 1, wherein each of said first ports is removably connected to a source of irrigation fluid and said second port is removably connected to a surgical instrument requiring a source of irrigation fluid for operation.

12. The valve assembly of claim 1 wherein said valve assembly is made entirely of a plastic material.
