Devices, systems, and methods for mitigating leakage from connectors and tubing of an endoscope system when the connectors and or tubing are disconnected from fluid ports of the endoscope system. A tubing assembly for connecting a fluid line to an endoscope and a fluid source may include an elongate tube having a lumen, a connector coupled to an end of the elongate tube and having a port in fluid communication with the lumen, and a fluid control component configured to selective adjust fluid flow through the lumen and the port. The fluid control component may be located in one or more of a cover for the fluid source, the tubing, the connector, and/or other components in fluid communication with the lumen. The fluid control component may be a valve. The valve may be manually actuated from a closed position to an opened position.

Methods and systems for coupling gas and water supply tubes to a container. An illustrative container and tube set may comprise a container configured to contain a fluid, the container having a bottom portion and a top portion, a water supply tube including a first end, a second end, and a first lumen, a gas supply tube including a first end, a second end, and a second lumen, and a weight coupled to the first end of the water supply tube and a first end of the gas supply tube. The first lumen may be in selective fluid communication with the bottom portion of the container and the second end of the water supply tube positioned external to the container. The second lumen may be in operative fluid communication with the container and the second end of the gas supply tube is positioned external to the container.

Methods and systems for supplying gas and water to an endoscope system. An illustrative container and tube set may comprise a container configured to contain a fluid and having a bottom portion and a top portion, a lens water supply tube including a first end, a second end, and a first lumen extending therethrough, a gas supply tube including a first end, a second end, and a second lumen extending therethrough, a port positioned adjacent to the top portion of the container, and a flexible tube including a first end coupled to the top portion of the container, a second end, and a third lumen extending therethrough. The third lumen of the flexible tube may be configured to be in selective fluid communication with the interior of the container.

A liquid sprayer powered by an inflatable standup paddle board (iSUP), comprising: a container; a sprayer hose; and an air hose. The container is configured to hold a liquid, the sprayer hose comprises a spray nozzle and is configured to pass the liquid from the container through the spray nozzle. The air hose may be configured to connect to the container and to an iSUP. The air hose may comprise a flow regulator and one-way check valve. The flow regulator is configured to start, stop, increase, and decrease a flow of air from the iSUP into the container. The one-way check valve substantially prevents the liquid from entering the iSUP. The container may accept the flow of air from the iSUP when connected to the iSUP, such that the container is pressurized. When the container is pressurized, the spray nozzle passes the liquid out of the liquid sprayer.

A dispensing system includes a motor driven air pump having an air inlet and an air outlet, and a dispensing device. The dispensing device is releasably connected to the air pump. The dispensing device includes an air connector connected to the air outlet of the pump, a mixture outlet, a product inlet, and a product uptake system connected to the air connector, the mixture outlet, and the product inlet. The dispensing system includes a product container for a product to be dispensed. The product container is connected to the product inlet. The product container is integrated in the dispensing device. The product uptake system may include an ejector for sucking product from the container and/or a container air inlet for pressurizing the container.

A device including a base containing a refill and a couplable lid in which an air pump, actuated locally or remotely via a messaging application, forces the air of the housing towards an ambient-air intake duct pressurizing the container with the refill, which naturally directs the air towards the fragranced-air outlet duct, releasing a dry jet of air through the fragranced-air overflow channel, located in the lid of the device.

A texture sprayer includes a main body and an inlet coupled to the main body. The inlet is configured to receive compressed air. A mixing chamber is disposed downstream of the inlet. The mixing chamber is configured to combine the compressed air with texture material to form a texture spray. A nozzle holder is coupled to the main body. The nozzle holder is movable between a first position and a second position. A first nozzle is coupled to the nozzle holder and a second nozzle is coupled to the nozzle holder. The texture sprayer is configured to discharge the texture spray along a spray axis through the first nozzle when the nozzle holder is in the first position and to discharge the texture spray along the spray axis through the second nozzle when the nozzle holder is in the second position.

A flexible dispensing apparatus for coupling to pressurized fluid containers is described. it includes a flexible tube and a handle assembly. The handle assembly houses a second end of the tube. The handle assembly has a first side connected to a second side, a slide trigger, a roller coupled to the bottom of the slide trigger with a dowel pin, a spray nozzle assembly, a magnet reservoir, and a magnet. The first side has an inclined ramp that runs along a length of the first side and extends into the second side above and beyond a seam that is formed by the connection of the two sides. The tube is within a channel in the handle assembly formed between the inclined ramp and the roller. When the roller is rolled toward the end of the ramp it pinches the flexible tube near the top of the inclined ramp.

Disclosed herein is a sprayer which may include, but is not limited to, a main body with a neck an inner cross section area of which gradually decreases; an air blowing module installed for air in the inside of the main body to be discharged to the outside; a liquid medicine container installed at a lower side of the main body and having air holes at a lid of the liquid medicine container; a nozzle cap having a minimum diameter part at an inner intermediate portion and assembled to the neck of the main body; a nozzle a rear end of which is open and connected to an end of a liquid supply pipe; and a rib which is configured to support in such a way that a central axis of the nozzle can position on a central axis of the nozzle.

An air scenting system for a vehicle is provided which includes an appliance and a replaceable cartridge installable therein. The replaceable cartridge contains a liquid compound to be aerosolized and has a cartridge outlet through which the aerosolized compound is discharged during operation. A pump is provided to supply air to the replaceable cartridge to generate the aerosolized compound from the liquid compound contained in the replaceable cartridge, and a controller is provided for controlling the pump to supply the air to the replaceable cartridge to generate and discharge the aerosolized compound from the appliance. The appliance is particularly adapted for dispensing scent into the interior space of a vehicle, and includes a form factor particularly well suited for positioning the appliance in a cup holder. Additionally, the appliance is designed for use in vehicles when a driver is present and readily adjustable by the driver to provide a uniform scent experience.
