Abstract: A breathing assistance apparatus includes a nasal mask unit, an insert plate, two nasal prongs, a head strap unit, and an intake tube. The nasal mask unit includes a rear wall having an inner surrounding surface defining a prong-receiving hole, a forwardly converging front wall formed with a tube-connecting hole, an insert groove formed in the inner surrounding surface, and two side straps extending respectively from two opposite sides of the rear wall. The front and rear walls define a compartment in fluid communication with the tube-connecting hole and the prong-receiving hole. The insert plate is inserted into the insert groove to thereby be positioned in the prong-receiving hole. Each of the nasal prongs has a nose-engaging end portion, a plate-engaging end portion fitted within the corresponding mounting hole, and a through hole. The head strap unit is connected between the side straps. The intake tube extends into the tube-connecting hole.

Abstract: A respiratory mask includes a teardrop-shaped front face member having a middle portion made of a transparent material and a lateral portion made of a colored material, and a rear cup member having a rear sealing portion adapted to contact a user's face, and a front portion connected to the front face member. The middle portion has a narrow top section and a wide bottom section. The lateral portion is connected laterally to the middle portion, and extends from one lateral side of the narrow top section, around the wide bottom section, and back to the other lateral side of the narrow top section. The middle and lateral portions are formed as a one-piece body. An air inlet is formed in the wide bottom section. Two strap-engaging portions are provided respectively on left and right sides of the lateral portion.

Abstract: A respiratory mask includes: a rigid mask frame having a ring portion, a loop portion spaced apart from the ring portion, and rib portions interconnecting the ring portion and the loop portion, the rigid mask frame defining a frame space; and a single piece of a flexible mask body having a flat central portion, a surrounding portion extending outwardly and curvedly from the flat central portion, and a peripheral end portion flaring from the surrounding portion. The flat central portion is formed with an annular flange sleeved on the ring portion. The peripheral end portion is disposed outwardly of the frame space. The surrounding portion extends into the frame space and is restrained by the rib portions and the loop portion of the mask frame.

Abstract: An atomizer includes: an enclosed reservoir defining an inner space adapted to receive a liquid therein; a jet nozzle provided in the inner space for passage of an air jet therethrough and formed with an air outlet; a jacket sleeved around the jet nozzle to define a fluid-introducing gap therebetween, the fluid-introducing gap being in fluid communication with the inner space; an air inlet conduit extending into the inner space, disposed above and connected to the jacket, and including a bottom wall having a jet-blocking portion aligned with the air outlet of the jet nozzle in a jet-ejecting direction, and a plurality of through-holes disposed around the jet-blocking portion and opening in the jet-ejecting direction; and a mist-discharging conduit extending sealingly into and in fluid communication with the inner space.
