A device for delivering medication to a user may include a circular or elliptical body that include a mouthpiece, a flexible strip of medication, a lever, and a mouthpiece cover, where the mouthpiece cover is rotatable about the body. The electronics module may include a communication circuit, a sensor system, and a switch. The lever may be configured to actuate the switch when the lever is moved from a closed position to an open position. The lever is configured to advance a dose of medication on the flexible strip when moved from the closed position to the open position. When actuated, the switch may be configured to switch the electronics module from an off state to an active state wen the lever is actuated for a first time by a user. Thereafter, the electronics module is configured to not return to the off state.

Disclosed are biofeedback methods and devices suitable for providing biofeedback useful for helping a user control an own breathing, for example, to help in inducing deep breathing, and such biofeedback devices further comprising a dispenser for dispensing an inflatable substance.

A device (400) for delivering medication to a user includes a circular or elliptical body (410) that includes a mouthpiece (420), a flexible strip (401) of medication, a lever (424), and a mouthpiece cover (491), where the mouthpiece cover is rotatable about the body. An electronics module (120) includes a communication circuit (134), a power supply (126), a sensor system (128), and a switch. The lever is configured to actuate the switch when the lever is moved from a closed position to an open position. The lever is further configured to advance a dose of medication on the flexible strip when moved from the closed position to the open position. The switch switches the electronics module from an off state to an active state when the lever is actuated for a first time by a user. The electronics module is configured to not return to the off state thereafter.

Aspects discussed herein relate to spirometers that can be used to measure lung function using a mobile device. A user can breathe into a mouthpiece that forces the user's breath through a spirometric encoding assembly. The spirometric encoding assembly can be coupled to a mobile device using a spirometric encoding adapter. The spirometric encoding assembly can generate one or more audible tones using the user's breath; these audible tones can be measured using a microphone of the mobile device. The audio data captured by the mobile device can be processed to determine the flow rate and/or volume of the user's breath. The flow rate and volume can be used to determine a variety of characteristics of the user's health, lung capacity, and/or for diagnosing medical conditions. A variety of treatment plans can be identified and/or administered based on the diagnosed medical conditions.

The present invention provides a method and device for detecting sleep apnea, which overcomes the current defect that it is hard to distinguish the type of sleep apnea. The method comprises: monitoring an instantaneous output power and an instantaneous rotation speed of a motor for delivering air in a breathing device (S110); according to the instantaneous output power and the instantaneous rotation speed of the motor, obtaining an airway flow reference value represented for the air in an upper airway of a user using the breathing device (S120); when it is determined that the user currently has no spontaneous breathing according to the airway flow reference value, and corresponding duration has reached a preset time threshold value, determining the user to be in an apnea state (S130); judging whether the upper airway of the user is clear (S140); and determining the apnea of the user to be central apnea (S150) or obstructive apnea (S170) depending on whether the upper airway of the user is clear. The method and device can accurately and effectively distinguish the type of sleep apnea.

A spirometer turbine assembly is described, having a housing with a proximal end opening, a distal end opening and an airflow channel therebetween. A first flow director has a first plurality of flow director blades with distal edges that curve in a plane perpendicular to a longitudinal axis of the airflow channel, and a vane is connected to an axel positioned distal to the first flow director. A spirometer turbine assembly having an anti-static material is also described.
