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.

A method and system for indicating a breathing pattern is disclosed. The system comprises a plurality of smart wearable devices, a plurality of mobile devices, an application server and a database. The plurality of smart wearable devices is either connected to the mobile devices or directly connected to the application server. The database is connected to the application server to store the data transmitted by the smart wearable device or the mobile device. The plurality of smart wearable devices is capable of monitoring the health index and identifying the variation in health conditions of the user, in real-time and activating a suitable breathing pattern to normalize such medical condition.

A system for respiratory training including a housing, a respiratory air channel disposed within the housing, a sensor configured to detect a breathing indicator and transmit a breathing indicator signal, a haptic device disposed within the housing, a processor operatively coupled to the sensor and the haptic device, and a memory device operatively coupled to the processor. The memory device includes instructions that, when executed by the processor, cause the processor to receive the breathing indicator signal from the sensor; generate a breath determination based on the breathing indicator signal; and responsive to the breath determination, cause the haptic device to generate a vibration.

Aspects of the present disclosure provide methods, apparatuses, and systems for non-linear breathing entrainment. As described herein, breathing entrainment refers to guiding a user's breath or breathing. According to an aspect, an initial breathing period and a final breathing period are selected. Based on the initial and final breathing periods, a non-linear breath rate per minute sequence is determined. A guiding stimulus is output and aligned with the non-linear breath rate per minute sequence. The guiding stimulus is non-linearly altered with the non-linear breath rate per minute sequence to align with the final breathing period over an interval of time. The non-linear alterations of the guiding stimulus vary based on an amount of time the guiding stimulus has been output.

The present invention provides a training device for training a user to use a pressurised metered dose inhaler (PMDI). The device comprises a body, air expulsion means (e.g. bellows) for expelling air along an air flow path and an actuator for actuation of the air expulsion means. The air flow path comprises a restriction such that upon expulsion of air along the air flow path, an audible signal is generated. The audible signal mimics that generated during use of a PMDI.

According to one embodiment of the present disclosure, provided is a meditation support device that is used by being held by hands, the meditation support device including: a sound output module that outputs sound whose volume varies in order to guide timing of respiration; and a vibration generator that generates vibration whose magnitude varies in order to guide timing of respiration.

A system to optimize diaphragmatic breathing is disclosed. The system has a first sensor to measure breathing movement of a user's abdomen and output a signal related to the movement of the user's abdomen, a second sensor to measure breathing movement of the user's chest and output a signal related to the movement of the user's chest; and a control device communicatively coupled with the first sensor and the second sensor. The control device has one or more processors, a memory comprising set of program modules executable by one or more processors. an assessment module for receiving the signal from the first sensor and second sensor and converting the signals to a data input, and for comparing the data input to a predetermined data range representative of proper diaphragmatic breathing for the user and a communication interface for providing feedback based on the assessment modules comparison of the data input and the predetermined range so as to optimize the user's diaphragmatic breathing. A method for optimizing diaphragmatic breathing is also disclosed.

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.

The present disclosure relates to a respiratory system for exercising and analysing respiration of a subject comprising: a breathing unit comprising: a mouthpiece connected to: at least one inhalation air way, at least one exhalation air way, and an electronic sensor unit comprising at least one pressure gauge for measuring air pressure in the mouthpiece, and a processing unit for collecting/storing and/or transmitting air pressure data.

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.
