Abstract

A splash shield for use in wound irrigation is provided. The splash shield includes at least one outlet area located along its rim so that irrigating fluid may flow from the splash shield. The splash shield is preferably oval-shaped with a substantially flat top adjacent to which is a receiver unit. The outlet area can be formed, for example, by contoured portions or by a generally V-shaped opening, each able to define a channel to enable the escape of fluid from the splash shield. The splash shield may be used in tandem with a syringe having a tip that is positioned in the receiver unit. Additionally, a basin can be provided for use during wound irrigation. The basin includes indentations to accommodate placement of a portion of the human body within the basin and an exit portion such that fluid in the basin can move in the basin to the edge of a table, bed, gurney or the like.

Claims

1. A wound irrigation device, comprising:

a body member having a top and an open bottom, said open bottom including outlet area portions and substantially flat portions integrally formed therewith, said outlet area portions allowing liquid to pass from said body member; and

an irrigating fluid input element that permits irrigating fluid to pass into said body member.

2. A device, as claimed in claim 1, wherein:

said body member being substantially oval-shaped having a maximum longitudinal extent and a maximum lateral extent, said maximum longitudinal extent being at least 1.2 times greater than said maximum lateral extent.

3. A device, as claimed in claim 2, wherein:

said body member has a height and said maximum lateral width is at least 1.5 times greater than said height.

4. A device, as claimed in claim 1, wherein:

said body member is substantially curved from said top to said open bottom and said flat portions lie in a plane, said outlet area portions being located outside of said plane of said flat portions.

5. A device, as claimed in claim 1, wherein:

said body member has a maximum longitudinal extent and said outlet area portions include contoured portions that extend along said maximum longitudinal extent greater than one-half of said maximum longitudinal extent.

6. A device, as claimed in claim 1, wherein:

said body member has a maximum longitudinal extent and a height, said outlet area portions include at least one opening that extends less than one-half of said maximum longitudinal extent and extends greater than 0.1 of said height.

7. A device, as claimed in claim 1, wherein:

said top of said body member has a substantially flat section and said irrigating fluid input element includes a bore element recessed relative to said flat section, said bore element for receiving a tip of an irrigating fluid supplying unit.

8. A device, as claimed in claim 7, including in combination therewith:

an irrigating fluid input unit having a tip that is located in said bore element.

9. A device, as claimed in claim 8, wherein:

said irrigating fluid input element further includes a constrictor element, said constrictor element being less in width than said bore element.

10. A wound irrigation device, comprising:

a body member having a top and an open bottom, said body member being substantially oval-shaped with said open bottom having a maximum longitudinal extent and a maximum lateral extent, said body member also having a height, said maximum longitudinal extent being at least 1.2 times greater than said maximum lateral extent and said maximum lateral extent being at least 1.5 times greater than said height; and

an irrigating fluid input element located adjacent said top of said body member.

11. A device, as claimed in claim 10, wherein:

said open bottom includes outlet area portions and substantially flat portions integrally formed therewith.

12. A device, as claimed in claim 10, wherein:

said maximum lateral extent is about 2.0 times greater than said height.

13. A device, as claimed in claim 10, wherein:

said top of said body member has a substantially flat section and said irrigating fluid input element includes a bore member for receiving a tip of a syringe.

14. A device, as claimed in claim 13, wherein:

said bore member is recessed relative to said flat section.

15. A device, as claimed in claim 10, including in combination therewith:

a basin including a number of walls, a central tray and a plurality of spaced indentations extending from at least one of said walls.

16. A device, as claimed in claim 10, including in combination therewith:

an irrigating fluid supply element selected from the group consisting of;

a syringe and a collapsible bottle.

18. A wound basin, as claimed in claim 17, wherein:

said central tray includes a support surface having sloping portions to direct fluid.

19. A wound basin, as claimed in claim 17, wherein:

said plurality of spaced indentations includes three indentations and said number of walls includes first and second side walls and an intermediate wall disposed between said first and second side walls, with one of said indentations extending adjacent to each of said first and second side walls and said intermediate wall.

20. A wound basin, as claimed in claim 17, further including:

a liner disposed over and covering said central tray.

17. A wound basin for use with a wound irrigating device, comprising:

a central tray;

a number of walls bounding said central tray; and

a plurality of spaced indentations extending inwardly from said walls towards said central tray.

21. A method for irrigating a body part, comprising:

providing a splash shield including outlet area portions adjacent to a bottom end of said splash shield;

connecting an irrigating fluid supply unit to said splash shield;

positioning said splash shield adjacent to the body part wherein at least portions of said bottom end contact portions of the body adjacent to the body part;

delivering irrigating fluid to said splash shield while said portions of said bottom end are in contact with the portions of the body adjacent to the body part; and

having irrigating fluid exit said splash shield at the same time said portions of said bottom end are in contact with the portions of the body adjacent to the body part.

22. A method, as claimed in claim 21, wherein:

said positioning step is conducted after said connecting step.

23. A method, as claimed in claim 21, wherein:

said outlet area portions interrupt said portions of said bottom end.
