A liquid dispensing device includes a body, a nozzle on an end of the body, a liquid container coupled to the body, and a piston configured to move in the body so as to control an ejection of liquid from the nozzle. The piston and the nozzle are configured to be detached from the body as an assembly.

A device for dispensing a mist of an ophthalmic fluid includes a discharge opening for said mist, a mixing chamber communicating with said discharge opening, an air chamber holding a volume of air, a first drive operable to expel air from said air chamber, a fluid chamber for holding a volume of the fluid to be dispensed and communicating with said mixing chamber, a second drive for delivering a predetermined dose of said fluid to said fluid chamber, said air chamber communicating with said fluid chamber and with said mixing chamber, said device establishing one flow of expelled air flowing into said fluid chamber, so as to force liquid from said fluid chamber into said mixing chamber, and another flow of said expelled air flowing past said fluid chamber into said mixing chamber.

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.

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.

This disclosure relates generally to a container and tube set and methods for fluid delivery, and particularly an integrated container and tube set suitable for use with an endoscope to supply liquids and/or gases to the endoscope. The integrated container and tubes may include a container (e.g., water reservoir) containing a fluid and a gas, and a plurality of tubes integrally formed with the container. The integrated container may include an irrigation supply tube having a first lumen in fluid communication with the fluid, a lens wash supply tube having a second lumen in fluid communication with the fluid, a gas supply tube having a third lumen in operative communication with the gas, and an optional alternative gas supply tube having a fourth lumen in fluid communication with the gas. The lens wash supply tube and the gas supply tube may be formed as a single, multi-lumen tube.

The invention relates to a dispensing device which is intended for spraying a sprayable fluid and is designed in the form of a hand-held unit, having a housing (12), in which are provided an air pump (22) and an electric drive motor (18), which drives the air pump (22), having a spray head (14), which is connected to the housing (12) and is intended for dispensing the fluid, having an accommodating chamber (29), which is arranged in the housing (12) and is intended for a storage container (41), in which the fluid which is to be dispensed is stored, having a fluid line (44), which leads from the storage container (41) to the spray head (14), and having a hose line (36), which leads from the air pump (22) to the spray head (14), wherein the spray head (14) has a first nozzle (46), which is connected to the fluid line (44), and, separately from said first nozzle, a second nozzle (38), which is supplied with the air flow from the hose line (36), and an atomizing zone (49) is formed outside the spray head (14).

A marker airbrush device for transferring marking solution from a marking device onto a writing surface using air is provided. The airbrush device includes a housing with an air outlet, a dual-action trigger for controlling an amount of air travelling through the air outlet, and a marker positioner coupled to the housing. The dual-action trigger may be either pushed down or pulled back to control air flow through the air outlet. The marker positioner positions a marking device relative to the air outlet such that air traveling through the air outlet contacts at least one surface of the marking device to transfer marking solution onto a writing surface. The marker positioner may include a rotatable collar that couples the marking device within the marker position and creates a seal around the marking device to prevent pressurized air from escaping around the marking device.

A marker airbrush device for transferring marking solution from a marking device onto a writing surface using air is provided. The airbrush device includes a housing with an air outlet, a trigger for controlling an amount of air travelling through the air outlet, and a marker positioner coupled to the housing. The marker positioner positions a marking device relative to the air outlet such that air traveling through the air outlet contacts at least one surface of the marking device to transfer marking solution onto a writing surface. In embodiments, rotation of a portion of the marker positioner advances and/or retracts the marking device with respect to the flow of air through the air outlet, thereby altering the angle and/or amount of air that contacts the marking device during spraying.

A disperser system includes a disperser body that defines a substantially air-tight chamber therein. A sprayer assembly includes a passage, a fluid coupling, a nozzle, a valve, a valve trigger and a pouch. The passage is in fluid communication with the chamber. The valve is in fluid communication with both the passage and the fluid coupling and opens to the nozzle. The valve trigger is configured selectively to open the valve, thereby placing the passage and the fluid coupling in fluid communication with the nozzle. The pouch contains a fluid. When the chamber is charged with a gas and when the valve is opened, the gas flows through the passage and the fluid flows through the fluid coupling into the valve so that the gas entrains the fluid and delivers a suspension of the gas and the fluid to the nozzle, out of which the suspension is sprayed.
