The present invention is an adaptor for connecting a pressurized gas, such as an oxygen supply, to two different outlets, with each outlet connected to a different gas delivery device. Gas delivery devices include, but are not limited to a nasal cannula, a c-pap machine, a bi-pap machine, a bubbler, or a nebulizer. The adaptor is provided with a valve located within the adaptor that can be used to direct the gas from the gas supply selectively to one of the two different outlets, or alternately, to both outlets at the same time.

A medical fluid suspension generating apparatus includes a Venturi-agitating tip assembly, a source of pressurized chemical solution, a source of a medical solution, and a dual lumen catheter connecting the Venturi-agitating tip assembly to the source of pressurized chemical solution and the source of the medical solution.

A breath-enhanced nebulizer adapted for use in administering an aerosolized pharmaceutical composition to a patient by inhalation wherein the patient is connected to a mechanical ventilator is disclosed. The nebulizer has a Venturi driven by a nebulizer air supply that draws a solution of a pharmaceutical composition into a shear zone where the solution is atomized. The Venturi effect is amplified by the internal configuration of the nebulizer to increase the rate of nebulization of drug. Optionally, breath-actuated nebulization is used, employing a pressure sensor interposed between the nebulizer and mechanical ventilator that controls the nebulizer air supply, such that nebulizer air and concomitant nebulization only occurs during the inhalation phase of a breathing cycle.

A dental mask (M) comprises a very flexible mask substrate (MS) with a relatively rigid front plate (FP) which may be a viewing window (VW) causing the mask substrate to extend forward from a patient's face, forming a chamber in front of the patient's mouth. Instrument ports (IP) allow instruments to be introduced through the mask into the patient's oral or nasal cavity to perform dental or medical procedures. An elastic band (CE) on the mask substrate to conform the mask to contours of the patient's face. A malleable metal strip (MM) for conforming the mask to the patient's nose. Methods of fabricating the mask are disclosed. The mask, and variations thereof, may be used to perform various treatments, including non-oral procedures. Using a nebulizer in conjunction with the mask, wherein the nebulizer is supported independently of the mask.

The present invention provides a gas generator, comprising a water tank and an electrolysis device. The water tank has a first hollow portion for containing electrolyzed water. The electrolysis device is disposed inside the first hollow portion of the water tank for electrolyzing the electrolyzed water to generate a hydrogen-oxygen mixed gas. When the electrolysis device starts to electrolyze the electrolyzed water, the first hollow portion of the water tank is filled with the electrolyzed water for standing at a full level of water. And after the electrolysis device electrolyzed the electrolyzed water, the level of water for the electrolyzed water filled into the first hollow portion of the water tank is higher than 95% of the full level of water. The gas generator of the present invention provides the design for saving space and nearly a zero gas chamber to reduce the possibility of explosions resulting from hydrogen-oxygen mixed gas.

Spray dispenser for nasal drugs includes a non-pressurized bottle for storing medical fluids in particular of drugs and other sterile fluids, a mounting body mounted to the top of the bottle and an actuating body, wherein the bottle, the mounting body and the actuating body are aligned along a longitudinal axis, and wherein the actuating body is slideably attached to the mounting body along the longitudinal axis and movable between an actuating position and a non-actuating position, wherein the spray dispenser includes an applicator nozzle and an actuating section for moving the actuating body into the actuating position, characterized in that the applicator nozzle has a nozzle axis which is inclined with respect to the longitudinal axis, the applicator nozzle facing away from the actuating section.

Methods and devices for delivering a dose, such as a medicament, for inhalation. A dose may be stored by a delivery device and dispersed and delivered in a metered fashion to a subject, such as by the subject inhaling via a mouthpiece of the delivery device. One or more chambers of the device may have a toroidal shape and may be arranged to be selectively opened for fluid communication with a flow path of the delivery device, such as by sliding the chamber relative to a portion of the flow path. The flow path may include a restriction that permits air to bypass the chamber, and/or the chamber may be arranged so that fluid entering the chamber interacts with fluid exiting the chamber so as to enhance dispersion of the dose.
