Abstract: A disposable pressure wound irrigation device is provided having a reservoir of cleansing solution disposed therein and a pressure chamber for providing a force upon the reservoir such that a liquid stream of cleansing solution is expelled at a constant pressure therefrom. Preferably, the propellant chamber will be provided with a regulator valve fitted within the pressure chamber for constantly monitoring the pressure which urges the chamber against the reservoir. An aimable outlet nozzle is provided through which the cleansing solution is expelled, the nozzle directing the flow of the cleansing solution to the wound surface. A release valve is further provided in order to selectively couple the nozzle with the reservoir, such that the cleansing solution may be evacuated therefrom through a passageway formed by a depression of the valve.

Abstract: A suction device that incorporates liquid to form a wet seal with a foreign body and/or debris, enabling an effective contact for extraction from canals, passages, and other bodily areas of a patient. A liquid chamber is formed between a distal nozzle and a distal end of a main body. The liquid chamber acts as a reservoir to facilitate a wet seal at the distal end of the embodiment. A vacuum provides suction through the embodiment, and a pressure release outlet is incorporated into the main body to allow for variation of suction force, affecting the moisture coverage presented to the area of extraction. Nozzle tip attachments may be affixed to the distal nozzle to further facilitate foreign body extraction. Other embodiments are described and shown.
