Abstract: A wound irrigation apparatus and process for safe cleansing of body wounds includes a pressure bladder disposed proximate a membrane sac holding a cleaning solution. Pressurizing the pressure bladder controllably pressurizes the cleaning solution. A conduit communicates the pressurized cleaning solution to a three-way valve. Operation of the normally off valve allows a steady stream of cleaning solution at a pressure of less than one atmosphere to be selectively directed to a wound for cleaning. The three-way valve includes an intermediate position which directs a gently pulsating stream of cleaning solution to the wound for enhanced cleaning action. The pulsation rate is directly dependent upon the pressure of the fluid and may be controlled. The valve includes a first elastic part and a second elastic part. The first part has an inlet with a larger diameter chamber into which the second part extends to form an integral valve unit.

Abstract: A sitz bath appliance for use with a hand held bidet is disclosed which enables conventional cleaning with the hand held bidet followed by closing of a drain with medicated, sanitary, constant temperature soaking. The sitz bath includes a circular rim configured on the lower surface for support on the upper rim of a toilet bowl with the seat up and configured on the upper surface as a seat. The supported sitz bath bowl is provided with overflow ports to maintain a constant level of liquid for soaking. The front of the bowl is configured with an integral molded channel in a raised rim portion to permit a hand held bidet to be inserted between the spread thighs of a user and thereafter used under the seated patient.
