A breathing training device for a subject, the device including at least one feedback member positioned in contact with the subject's abdomen near the subject's diaphragm; and, an attachment member at least partially extending around the subject, wherein the attachment member and the feedback member cooperate to mechanically provide discrete tactile feedback to the subject when the abdomen reaches a predetermined level of expansion.

A blowout includes: a stretchable body having a tube shape and changeable in shape; a wire body having elasticity and arranged along the longitudinal directions of the stretchable body; a pipe body having a cylinder shape, one end part of the pipe body being connected to one end part of the stretchable body; and a mouthpiece body having a cylinder shape and connected to the other end part of the pipe body, the mouthpiece body being held by a user in the mouth such that air is blown by the user, in which the stretchable body is stretched by blowing air from the mouthpiece body while the stretchable body is curled into a spiral by the elastic force of the wire body when air is not blown from the mouthpiece body. In the blowout, the one end part of the stretchable body and the one end part of the pipe body are connected by a tightening band so that the stretchable body can be attached to and detached from the pipe body.

A positive pressure airway device for providing resistance in an air pathway for a patient exhaling. The device includes a central tube region, a inspiratory air passageway for passing air into the central tube region when a patient breathing through the device inhales, and an expiratory air passageway for passing air out of the central tube region when a patient breathing through the device exhales, A valve in the expiratory air passageway allows air to flow out only when a patient using the device exhales with an expiratory air pressure greater than a selected pressure, and includes a stopper and a coil spring with an interior portion that is free from any structure that would inhibit the “side-to-side” movement of the spring within the housing. The stopper has a cone-shaped air-stopping surface providing a valve angle that is different from the valve-seat angle so that either laminar or oscillating flow may be obtained.

A spirometer-type device is described that is designed to improve patient compliance with therapeutic breathing for improved pulmonary function. In an example embodiment, a display of human lungs is provided that visually elevate with inhalation. A patient's progress is visualized with a featured conspicuous level marker and upward motions of lungs that are seen from both sides of the device.

A respiratory therapy apparatus includes a rocker mechanism (101, 110, 111, 112) that provides an oscillating resistance to expiration. The apparatus also includes an air entrainment arrangement (200) at its air inlet (3) having a ring orifice (214) connected via a gas inlet (4) to a source (119) of oxygen at elevated pressure. The oxygen emerging around the ring orifice (214) entrains ambient air and supplies this as a continuous flow of respiratory gas to the patient interface (2) to provide a positive airway pressure.

A respiratory rehabilitation apparatus includes a housing, an adjustment rod provided in the housing to change a pressure load generated during respiration, a pair of stoppers for selectively adjusting respiration pressure, a pair of pressurization-movement parts configured to be pressurized and moved inwards in a longitudinal direction of the housing by respiration pressure during respiration, a pair of elastic members disposed between the pressurization-movement parts and the stoppers, and a pair of diaphragms disposed so as to be in close contact with outer sides in a longitudinal direction of the pressurization-movement parts.
