摘要:
The invention provides a beverage carbonator (1) for providing a carbonated beverage (2). The beverage carbonator (1) comprises (a) a CO2 generation unit (10) comprising a photo electrochemical cell (22) arranged to convert an organic compound (23) in a first liquid (21) comprising the organic compound (23) under influence of light (24) into at least CO2 and to produce a CO2 comprising gas (25), (b) a pressure regulator (30) arranged to pressurize the CO2 comprising gas (25), and (c) a mixing chamber (40) for mixing the CO2 comprising gas (25) under pressure into a second liquid (41) to provide the carbonated beverage (2).

摘要:
The interdental cleaner includes a source of liquid (22) and a control system (42) including a manual pump (26), for moving a selected amount of liquid, suitable for a single use, into a liquid pathway and there to a mixing chamber (53). A source of pressurized gas (30), such as a CO2 cartridge, is used to preload a selected amount of gas into a gas chamber (52). The control system includes a spring-loaded button (18), which upon operation results in the manual pump (26) being operated, forcing the selected amount of liquid into the mixing chamber, and then upon release, permits the pressurized gas in the gas chamber to enter the mixing chamber, breaking up the liquid therein into droplets and a liquid stream, and propelling the resulting liquid out of a nozzle portion (14) of the cleaner into the interproximal area of the teeth.

An insert for a breast-receiving funnel (10) of a breast pump comprising an elongate inflatable bladder (23) which defines a pressure chamber (26), the elongate inflatable bladder (23) being adapted to fit in a teat receiving space (11) of said breast receiving funnel (10) so that the bladder extends from an inner end of said funnel towards an outer end of said funnel, and lie between a user's teat and the funnel when a breast is inserted in the funnel, such that the elongate inflatable bladder is configured to deform towards a user's teat located in the teat receiving space in a predetermined manner when a pressure difference is applied between the teat receiving space and the pressure chamber such that a peristaltic action is applied to said user's teat, to aid the expression of milk therefrom.
摘要:
An appliance and corresponding method for delivering antimicrobial agents to the vicinity of dental biofilm and for killing bacteria therein includes a system (18, 20, 24) for delivering polymeric capsules containing gas bubbles and an antimicrobial agent. A source of ultrasonic energy (18) is provided for moving the capsules toward the biofilm, the ultrasonic energy having sufficient intensity for thereafter bursting the capsules, in the vicinity of the biofilm, releasing the gas bubbles and the agent. The gas bubbles vibrate within the ultrasound field, disrupting the biofilm, so that the released agent can act effectively against the bacteria in the disrupted biofilm.
摘要:
The system includes a reservoir for fluid; a droplet generator for creating a stream of fluid droplets from the fluid wherein the velocity of the stream of droplets is within a range of 20 meters per second to 200 meters per second and the size of the droplets is within a range of 5 microns to 200 microns. A nozzle or nozzles direct the stream of droplets to safely clean a selected tooth or teeth surface area. The specific momentum of effective fluid droplets within the stream of fluid droplets is important in safe and effective cleaning.

A breast pump insert to receive the breast of a user of a breast pump is disclosed. The insert is formed from inner and outer materials, wherein the outer material exhibits greater hardness than the inner material.
摘要:
A multi-switch (24) for an oral care appliance includes a switch housing (28) having a hollow chamber (30) therein, a button actuator (32) with at least two O-rings (42) around the periphery thereof, and inlet and outlet channels (50, 52) connecting a source of compressed gas (18) with the housing chamber and the housing chamber with a mixing chamber (26), respectively. A pump (60) moves fluid from a reservoir (20) to the mixing chamber. The O-rings are positioned so that as the button actuator is actuated and then released, the outlet is closed and the inlet is opened, allowing gas to move into the housing chamber. The pump is actuated, and then the inlet is closed and the outlet opens, allowing gas in the chamber to move to the mixing chamber to produce a stream of fluid droplets, which are directed out through a nozzle portion (16) of the appliance.
摘要:
The interproximal cleaning appliance includes a housing (12) and a spray applicator (16) extending therefrom for directing a spray of fluid droplets to the interproximal area. Within the housing is a spray-generating assembly (14) which includes a chamber, a movable piston (26) mounted therein, one-way inlets (42, 40) for gas and fluid and an outlet (44). A system (54) for moving the piston, such as a motor, operatively compresses a spring (32) which creates a partial vacuum in the chamber, allowing gas to flow into the chamber through the gas inlet. Release of the spring produces a stream of fluid droplets which flows out of the chamber through the applicator to the interproximal area.
