An instrument includes an ultrasonic blade, a first fluid port, an irrigation member, a second fluid port, and a fluid communication assembly. The ultrasonic blade defines a distal opening. The ultrasonic blade is operable in a first mode to emulsify tissue that is distally positioned relative to the ultrasonic blade. The ultrasonic blade is further operable in a second mode to transect and seal tissue that is transversely positioned relative to the ultrasonic blade. The first fluid port is in communication with the distal opening of the ultrasonic blade. The irrigation member is positioned adjacent to the distal end of the ultrasonic blade. The second fluid port is in communication with the irrigation member. The fluid communication assembly is configured to couple the first fluid port with a fluid source, couple the first fluid port with a suction source, and couple the second fluid port with the fluid source.

A cap and container assembly is disclosed which may be used for human body cavity irrigation or other liquid dispensing activities. The cap may include a first channel extending from a base through a neck portion to an opening in a tip portion of the cap. A side body defining a second channel may extend from the first channel near the neck portion of the cap to an opening at a distal end of the side body. An axial dimension of the tip portion may extend at an angle relative to an axial dimension of the neck portion. Liquid may flow out of the first channel under the influence of gravity and as a result of control of air flow into the second channel.

This application presents methods and devices for continuously cleaning a colon by at least partially filling a segment of the colon with liquid and agitating the fluid to dislodge matter adhering to the colon walls. Methods for automatic maintenance of liquid levels in the colon during continuous cleaning are taught.

An apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. The cleansing means (which may be a single-phase, e.g. microfiltration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing and a method of treatment using the apparatus.

An article is described including an article surface and a coating set comprising an optional tie coating or layer, a barrier coating or layer, and a pH protective layer. The respective coatings or layers can be applied by chemical vapor deposition of a polysiloxane or polysilazane precursor in the presence of oxygen. Examples of such an article are a thermoplastic syringe, vial, or blood collection tube with a coated interior portion containing a pharmaceutical preparation or other fluid with a pH of 4 to 8, alternatively 5 to 9. The barrier coating or layer prevents oxygen from penetrating into the thermoplastic syringe, vial, or blood collection tube. The tie coating or layer, if present, and the pH protective coating or layer protect the barrier layer from the contents of the syringe, vial, or blood collection tube.

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.

Systems and methods for cleaning body cavities are presented. Some embodiments reduce size of fecal matter pieces within an evacuation conduit. Some comprise devices and methods for purging an evacuation conduit. Some comprise reduced cross-sectional profiles of a cleaning device. Some protect intestinal tissue by preventing exposure to excessively high and low pressures.

Systems, devices, and methods are disclosed for maintaining oral hydration. A device may include a perforated tube, covered by an outer cover made of an absorbent material. The tube may be shaped such that it allows a patient using the device to open and close his or her jaw, without displacement and also to allow other medical devices to be used on the patient simultaneously.

A fluid source management system (100) comprising a structure (101) that supports one or more fluid sources (103), sensors (102) that determine the fluid state of the fluid sources (103), at least one common reservoir (108) for storing the fluid, tubing (104) connecting the fluid sources (103) to the common fluid reservoir (108) and a controller (105) that controls the opening and closing of the tubing (104) based upon the fluid state of the fluid sources (103).

Systems and methods for cleaning a colon or other portion of an intestine include optional use of sensors to detect conditions of blockage of flow of materials within an evacuation channel used to remove fecal material from the body; and devices and methods for purging such blockages from the evacuation channel.
