A respiratory pressure training strap includes a waist-back support, two shoulder straps, a chest strap and a belly strap; wherein the waist-back support is a main body of the respiratory pressure training strap, an upper portion of the waist-back support is connected to first ends of the shoulder straps, and a lower portion of the waist-back support is connected to the belly strap as well as second ends of the shoulder straps; wherein two ends of the chest strap are respectively connected to a left shoulder strap and a right shoulder strap of the shoulder straps; wherein the belly strap laterally extends from the lower portion of the waist-back support; wherein respiratory pressure regulators are respectively arranged on the waist-back support, the chest strap, and the belly strap. The present invention can realize the respiratory posture correction for the user by the reverse pressures.

A respiratory therapy device having a diagonal feedback array, and methods for the user thereof.

A portable user device, method and computer program provide rhythmic athletic training assist by tracking an athletic proficiency level of a user. A respective sport control affordance for a plurality of sports are presented on a user interface of the portable user device. In response to a user selection of one sport control affordance associated with a selected sport, more than one drill control affordance for a type of athletic drill associated with the selected sport are presented on the user interface. In response to a user selection of a particular drill control affordance for a particular type of athletic drill, the type of athletic drill is associated with two or more available rhythmic speed settings. Based upon the tracked proficiency level of the user, one of the two or more rhythmic speed settings is selected. Video/audio guide is presented on the user interface at the selected rhythmic speed setting.

Method and apparatus varies the oxygen concentration level of air delivered to a person for treatment on training purposes. The apparatus includes a display device for displaying current physiological data as well as data from previous sessions for comparison purpose. The oxygen level is precisely controlled by a central processing unit in response to input data from the person.

An apparatus and methods for air filtration are disclosed. The apparatus includes a body and first and second replaceable filters. The body of the apparatus further contains an air-exchange assembly and a filter receiver attached to the air exchange assembly. The air-exchange assembly contains an exhaust tube with an open end and a closed end, two wings on opposite sides of the exhaust tube, and an intake check valve and an exhaust check valve inside the exhaust tube. The first replaceable filter surrounds the filter receiver; and the second replaceable filter is inside the filter receiver. Several apertures and the check valves are strategically disposed in the exhaust tube to achieve optimal air filtration and avoid contamination of a user's exhaust.

A musical instrument therapy device for providing strengthening therapy for sleep apnea treatment. Utilization of the device can help to strengthen the user's muscles of the throat and tongue, which can help the user to maintain an open airway during sleep (reduce airway collapse) and prevent airway blockages, thereby reducing the chance of obstructed breathing during sleep. The musical instrument therapy device comprises: a tubular body defining an air column; a mouthpiece located at a first end of the tubular body configured to receive a blow input; a mute located at a second end of the tubular body configured to mute the blow input; a plurality of sensors configured to obtain measurements associated with the blow input; a processing unit configured to make one or more determinations associated with blow input based on the obtained measurements; and an indicator configured to display an indication of the one or more determinations.
