An assembly for nasal irrigation for the handheld irrigation of a user's nasal cavity comprising a housing with a refill chamber containing irrigating fluid, an applicator, an actuator for forcing irrigating fluid from the refill chamber through the applicator into the user's nasal cavity during operation, and a solution port for refilling the refill chamber. Some embodiments of the present invention may further comprise a system for nasal irrigation that includes the assembly for nasal irrigation or handheld irrigator, as well as a solution assembly structured for dispensing irrigating fluid to the handheld irrigator, a docking station for removably housing the handheld irrigator, a solution assembly and a refill control, including a check valve.

A fecal collection device includes a barrel with a waste drain conduit attached thereto. A drain opening is defined between passages of the barrel and the waste drain conduit. An irrigation conduit is connected to a source of lavage liquid. A trocar plug has a tapered distal end and moves between insertion, irrigation and flushing positions within the barrel passage. When in the insertion position, the tapered distal end of the trocar plug extends from the distal end of the barrel. When in the irrigation position, the irrigation conduit may provide lavage liquid to the barrel passage while the trocar plug covers a majority of the drain opening. When in a flushing position, the trocar plug covers less of the drain opening than when the trocar plug is in the irrigation position.

This system for in-body-cavity liquid perfusion of a circulating type which circulates a liquid such as an isotonic solution perfused within the body cavity, suppresses an excessive increase in internal pressure that would lead to breakage of a hollow fiber membrane module. A drain valve is connected to a drain port of the hollow fiber membrane module. A pressure sensor measures the internal pressure of the hollow fiber membrane module. A control unit opens the drain valve on the basis of the internal pressure of the hollow fiber membrane module measured by the pressure sensor, draining foreign matter from the hollow fiber membrane.

There is provided a colon cleaning device comprising: a tube through which liquid and fecal matter are removed from a colon of a patient, the tube having a longitudinal axis; a cleaning head positioned at the distal end of the tube, the cleaning head having at least one opening coaxial with the longitudinal axis, the at least one opening sized for fecal matter to enter the interior of the cleaning head from the colon; at least one disassembly element disposed within the cleaning head; and an actuating mechanism which actuates the disassembly element to perform sweeping displacement inside the cleaning head so that the at least one disassembly element rotates around the longitudinal axis to slice through the fecal matter; wherein the cleaning head and the tube are sized and shaped to be displaced along the colon of a patient.

The subject invention provides novel and highly effective methods and devices for convenient and effective wound irrigation.

Systems and methods for nasal irrigation are provided in which a nasal irrigation device includes a source of saline solution, an effluent receptacle, a nasal interface, a vacuum source, a fluid passageway to communicate the source of saline solution with the effluent receptacle through the nasal interface and a nasal cavity of the user, and a switch and valve assembly for selectively controlling the vacuum source and flow of the saline solution through the fluid passageway. The saline solution source bottle is disposed relative to the device to provide gravitational inducement of saline solution to the nasal interface in engagement to the device user's nostrils. A combination of the gravitational inducement and the relative vacuum from an effluent receptacle generates a fluid flow for irrigating, cleansing and massaging the nasal cavity and ostia of a user. The entire device is assembled as a hand-held device for convenient lifting and disposal against the user's nostrils.

A wound irrigation system and apparatus for irrigating a wound comprising an irrigant reservoir for holding an irrigant solution, a delivery line, a flow regulator, a pump in communication with the reservoir to apply pressure to the reservoir and an irrigation attachment that can be arranged in varying configurations in a wound site to allow uniform irrigant coverage in a wound site on a patient. The irrigation attachment is comprised of a trunk line and branch lines that are in fluid communication with the trunk line and whereby said branch lines can be manipulated into position by a healthcare provider into the appropriate areas of a wound site.

A system and method to irrigate a user's auditory canal. A fluid can be dispensed from a reservoir through a fluid path and out through openings of a delivery element into the auditory canal. A pump may be used to facilitate the process of dispensing the fluid. The fluid can be delivered to the user's auditory canal for a predetermined period of time. Such a time period may be user selectable. The discharge from the irrigation is removed from the user's auditory canal via a discharge port located on the delivery element. The discharge exits the delivery element and proceeds to a discharge reservoir via a discharge path. A vacuum may be used to generate a negative pressure to facilitate the removal of the discharge from the auditory canal.

A fluid collection device includes a upper edge portion having a first end of a collection container having an outer surface where the upper edge portion defines an open top end. At least one adhesive surface may be attached to the outer surface of the collection container. A vacuum hose coupled to an outlet port extends from a second end of the collection container. A vacuum source applies a vacuum to the collection container through the vacuum hose.
