Methods and devices for providing liquids to nasal and/or paranasal cavities are disclosed. Probe portions of a first and of a second probe are introduced to a user's first and second nostril, respectively. Each probe has a primary channel and a secondary channel. Fluid is provided to the secondary channels to expand the expandable portions of the secondary channels, seal the nostril openings and expand alar sidewalls of the nostrils. This may reveal ducts that lead to the paranasal cavities. The liquid is provided through the primary channels to the nasal cavity, the liquid being disposed to reach and stimulate the soft palate, and may trigger a swallow reflex to raise the soft palate and exert pressure to the liquid, the liquid may find an escape route through the ducts and into the paranasal cavities.

A method of determining a pressure of a body cavity with a controller of a fluid management system includes determining a pressure and a volume of a cuff disposed about a collapsible bag, determining a volume of the collapsible bag based on the pressure and the volume of the cuff, and determining a pressure of the collapsible bag based on the volume of the collapsible bag. The method also includes calculating a fluid flow from the collapsible bag into a body cavity from the collapsible bag and determining a pressure of the body cavity based on the fluid flow.

A fluid infusion system includes an air pump connected to an accumulator tank to produce pressurized air that is stored in the accumulator tank. The system can include one or more fluid bag chambers wherein each fluid bag chamber includes an inflatable bladder positioned inside the fluid bag chamber to apply pressure on the fluid bag supported inside the chamber. The fluid bag can be connected by a tube set to deliver fluid from the fluid bag to a surgical tool at a surgical site. The fluid can, for example, be irrigation fluid or distention fluid. The system can include a controller connected to the pump to control the pump to produce the pressurized air and an adjustable pressure regulator can be connected between the accumulator tank and the inflatable bladder to control the pressure of air delivered to the inflatable bladder and the pressure that the fluid is delivered to the surgical tool. A pressure sensor can be connected between the adjustable pressure regulator and the inflatable bladder to measure the air pressure delivered to the inflatable bladder and send the air pressure measurements to the controller. The controller can configure the system display to show the air pressure measured by the pressure sensor.

A system for applying a lavage fluid to a surface, the system having a body configured to house a lavage fluid and at least two interchangeable application members configured to be in fluid communication with the body, wherein the at least two interchangeable application members includes a first application member and a second application member, the first application member being configured to dispense the lavage fluid with a first fluid flow force and/or first fluid flow pattern, and the second application member being configured to dispense the lavage fluid with a second fluid flow force and/or second fluid flow pattern that is different from the first fluid flow force and/or fluid flow pattern, respectively.

A system for applying a lavage fluid to a surface, the system having a body configured to house a lavage fluid and an application member in fluid communication with the body, wherein the application member has at least one nozzle, wherein the system is configured to dispense the lavage fluid with a first fluid flow force and a first fluid flow pattern, and wherein the nozzle is configured to selectably dispense the lavage fluid with a second fluid flow force and/or a second fluid flow pattern, wherein the second fluid flow force that is different from the first fluid flow force and the second fluid flow pattern is different from the first fluid flow pattern.

A fluid delivery system includes a pressure source capable of producing both positive and negative fluid pressure, a fluid infusion line, and a first fluid storage container. The first fluid storage container includes a chamber, a fluid outflow port that is connectable to the fluid infusion line to provide fluid communication between the chamber and the fluid infusion line, a pressure inlet that is connectable to the pressure source, and a filter disposed between the pressure inlet and the chamber. The fluid delivery system further includes a control system configured to cause the fluid pressure source to apply both negative pressure and positive pressure.

A system for anal irrigation is provided. The system includes a container, an anal probe, tubes and an electrical pump. The container has two configurations, a first collapsed configuration and a second expanded configuration. In the first configuration, a cavity for storing tubes and the anal probe is provided. In the second configuration, the container has a cavity for containing irrigation liquid. The pump and valves is stored in a cavity towards the bottom of the container.

A spray canister device includes a canister containing a liquid product, a canister housing having an opening, a chassis element, and a tray slidably coupled to the chassis element. The canister includes an actuator cap and is positioned in the canister housing such that a nozzle of the actuator cap is positioned proximate the opening. The canister housing, and the canister positioned therein, may be engaged with the tray via at least one protruding member. Once engaged, the tray may be slidably moved along the chassis element between a retracted position and an extended position to facilitate relative movement between the canister and the canister housing to compress the actuator cap of the canister and spray the liquid product.

Aspects of the present invention provide a method for using an apparatus to deliver medicine and to wash, clean, and dry a region of a human body. The apparatus include a toilet seat assembly and a medicine delivery assembly. In addition, the apparatus may include a drying nozzle assembly and/or a spraying nozzle assembly. The medicine delivery assembly may include one or more medicine storage cartridges and/or one or more medicine base units, each medicine base unit includes at least a cartridge unit and at least a cartridges slot, wherein the cartridge slot is adapted to match with a medicine storage cartridge. The medicine delivery assembly may include a medicine delivery nozzle, which can be coupled to a spraying nozzle assembly, or may be operated by itself with a medicine delivery nozzle. Finally, the medicine delivery assembly can be controlled by one or more control units.
