An apparatus and method for providing a nebula or aerosol to a patient is described. In one aspect, the nebulizer is composed of a minimum number of parts to reduce complexity for automated or human assembly. The nebulizer may include an inhalation valve, exhalation valve and biasing member integrated into a single diaphragm structure that may be connected with an actuator and inserted into a housing for controlling nebulization of a medicine to a patient in response to the patient's breathing or in a continuous nebulization mode.

Nebulizer apparatus and method

A nasal mask has a flexible bottom edge portion and side portions. A delivery device includes a holding chamber coupled to the nasal mask. A method of delivering an inhalable substance includes positioning a nose of a user in a cavity of the nasal mask, inhaling through the nose, and orally soothing the user with a soothing device.

Delivery device and kit, and method of use

A delivery device includes a toroidal shaped housing defining an interior chamber and a central open space. The housing includes an input port communicating with the interior chamber and a delivery port positioned on an inner periphery of the housing. The delivery port is in fluid communication between the interior chamber and the central open space. The delivery port is spaced from the input port, which is adapted to receive an aerosolized medicament. In another aspect, a kit includes an outer ring-like housing component and a plurality of differently configured inner ring-like housing components mateable with the outer ring-like housing to form a holding chamber. A method of delivering an inhalable substance is also provided. A mask, including mounting and sealing portions is also provided, together with a method of manufacturing such a mask. Delivery devices include various alternative adapters to be used with a mask and a substance dispenser.

A breathing assistance apparatus includes an inner volumetric member pressurizable from a first pressure to a second pressure and an outer volumetric member surrounding at least a portion of the inner expandable volumetric member. The inner volumetric member pressurizes the outer volumetric member as the inner volumetric member is pressurized from the first pressure to the second pressure. In another embodiment, a breathing assistance apparatus includes exhalation and inhalation chambers with respective biasing members providing for the exhalation chamber to apply a pressure to the inhalation chamber and thereby provide assisted inhalation. Methods for assisting breathing are also provided.

Breathing apparatus and method for the use thereof

A nebulizer includes a housing having a chamber for holding an aerosol, an air outlet communicating with the chamber for permitting the aerosol to be withdrawn from the chamber, and a reservoir for holding a liquid to be aerosolized. The nebulizer also includes a liquid orifice located in the chamber, one or more liquid channels defined between the reservoir and the liquid orifice, the one or more liquid channels having a liquid volume, and a pressurized gas outlet located in the chamber adjacent to the liquid orifice. A baffle is located in the chamber and positioned relative to the pressurized gas outlet and the liquid outlet so as to divert pressurized gas from the pressurized gas outlet and over the liquid orifice. The baffle has a diverter surface area. The liquid volume is at least 80 mm. The diverter surface area is less than 5.0 mm.

In another aspect, a kit includes an outer ring-like housing component and a plurality of differently configured inner ring-like housing components mateable with the outer ring-like housing to form a holding chamber. A method of delivering an inhalable substance includes positioning a nose and a mouth of a user in a central opening defined by a ring-like housing, inhaling through the nose, and orally soothing the user with a soothing device located in the central opening.
