Abstract
A wound irrigation apparatus comprising a fillable fluid delivery member, a fluid channel, and a splash shield for use in wound irrigation is disclosed. The splash shield is a three-dimensional shield positionable about a wound to protect medical personnel from the back splash resulting from wound irrigation and is at least partially flexible and compliant for shaping the shield to fit the unique shape or dimension of a wound. The flexible peripheral edge of the splash shield also prevents damage to the wound if the shield should come in contact with the wound. The shield may also be structured to provide selective angular adjustment of fluid delivery to the wound. The shield of the present invention generally comprises a shield member and a hub positioned through the surface of the shield member to direct fluid to a wound. The shield member may be structured to provide selective angular positioning of the hub to selectively direct fluid to the wound site. The fluid channel may be variable in length, internal diameter and bore shape to selectively determine the pressure at which fluid is delivered to the wound site and to selectively determine the spray pattern. The wound irrigatio…
