A breath training device to assist a user in conscious breathing and breathing exercises. The device includes a vibratory motor that can generate vibration pulses at predefined intervals that corresponds to the vibration rhythm pattern set by the user. The user can coordinate the breathing based on the vibration pulses. A timing circuitry to close the device after a predefined duration can also be provided. The device is customizable, wherein the vibration rhythm pattern, intensity of vibration pulses, and predefined duration can be modified.

This invention relates to a device for ventilating a subject and a system comprising such a device, in particular a virtual reality system. It also relates to a kit comprising such a device or system, as well as a virtual reality content attached to a computer medium. The invention also relates to the applications liable to be made of these devices, system and kit, particularly in the medical, well-being and gaming fields.

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 method of and device for acquiring in-vivo images or quantitative/qualitative data (perfusion, blood flow, vascularization, contrast enhancement, selective blood supply management) of interior parts of the human body using an imaging system includes the steps of positioning the body relatively to the imaging system, applying a respiratory resistance device to the respiratory system of the body, and performing an image acquisition step during or concomitantly an inhalation/inspiration/suction or exhalation/Valsalva/expiration phase, during which the body provides suction or exhalation against a resistance as provided by the respiratory resistance device.

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 inhalable substance.

Systems, devices, and methods for determining a user's lung capacity may employ a sound-producing breathing device and a recording device such as a microphone included in a user electronic device (e.g., smart phone or tablet computer). A user may inhale or exhale through the sound-producing breathing device, thereby producing a sound that is received by the microphone and communicated to a processor. The processor may analyze the received sound recording to determine one or more sound intensity values over, for example, the duration of the received sound and/or points in time within the sound recording. The sound intensity values may then be used to determine the user's lung capacity.

An oscillating positive expiratory pressure system including an oscillating positive expiratory pressure device, an adapter coupled to the device, and a control module coupled to the adapter. The control module provides real time information about the use of the device, and provides feedback and storage of the information to improve the use thereof.

Various improvements are provided to breathing training, monitoring and/or assistance devices. A portable device is provided which optionally includes a gas canister, a feedback system for implementing pressure control, and a visual output for indicating adherence to a breathing exercise to the user. The pressure control may provide regulation of different pressures for inhalation and exhalation.

There is described a method for coaching a breathing exercise to a user using a computing device. The method provides a sequence of user instructions for the breathing exercise and determines an expected pattern of breathing intensity from the user in accordance with the sequence of user instructions. Raw audio data stream is retrieved from a microphone associated to the computing device. The raw audio data stream is processed, and breathing events are then detected. By comparing a timing of the detected breathing events with the expected pattern of breathing intensity, compliance with the breathing exercise and future exercises can be adapted within a session or over the length of a program.
