A respiratory therapy device that is adapted to matingly connect with two standardized respiratory devices simultaneously to allow for combination, enhanced, single device, respiratory treatments. It monitors the number of PEP treatment events utilizing a motion sensor, and presents a resettable, visual stimulus for each event as well as providing a record of the events in each therapy cycle.

A respiratory therapy device that is adapted to matingly, frictionally connect with dimensionally standardized devices and device adaptors, that when combined, allow for respiratory treatments. It monitors the direction of the air and or medicament flow (gases) in the device and can visually report as well as record the number of PEP treatment events or the number of medicament administrations by utilizing at least one bidirectional motion sensor therein. It presents a resettable, visual indicator for each pulse of gas that passes along its interior passage as well as providing a stored and transmittable record of these pulmonary events. It has an energy saving mode that will only allow the unit to be powered for operation when it is being handled.

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

The invention relates to a respiratory flow sensor comprising a flow pipe, which has a flow channel and, on the free ends thereof, hose connections for hoses, comprising a cover flap, which is arranged in the flow channel and divides the flow channel into a first flow channel portion and into a second flow channel portion, and comprising connections, which lead into the flow channel on both sides of the cover flap and serve for the reduction of the differential pressure created by the cover flap. Provision is made in the flow channel for a water drainage device, which comprises drainage grooves. The cover flap has a hinge region, which is formed by a first slot and a second slot, which is embodied in an H-shaped manner.

A medical device for treating an associated patient includes a bronchial sensor device configured to measure fluid pressure in a bronchus of the associated patient; and an electronic controller configured to: receive the fluid pressure data from the bronchial sensor device; and calculate a fluid flow measurement through the bronchus based on the measured fluid pressure.

A single sensor capable of detecting both airflow in spirometry and the full range of sound frequencies needed to track clinically relevant breath sounds is provided. The airflow sensor includes a movable flap with one or more integrated strain gauges for measuring displacement and vibration. The airflow sensor is inherently bidirectional. The sensor is an elastic flap airflow sensor that is capable of detecting data needed for both spirometry and auscultation measurements. The sensor is sterilizable and designed for the measurement of human respiratory airflow. The sterilizable sensor is also suitable for non-medical fluid flow metering applications. Additional devices such as sensors for the ambient level of various chemicals, sensors for temperature, sensors for humidity and microphones, may be affixed to the flap. When the strain gauge is placed in a conventional Wheatstone bridge configuration, the sensor can provide the airflow measurements needed for medical spirometry.

The invention relates to a respiratory flow sensor (11) comprising a flow tube (12) which has a flow channel (13) and tube connections for tubes at the free ends (15, 17) of the flow tube, a cover flap (32) which is arranged in the flow channel (13) and divides the flow channel (13) into a first flow channel section (18) and a second flow channel section (19), and comprising connections (22, 23) which open into the flow channel (13) on both sides of the cover flap (32) and which are used to decrease the pressure difference generated by the cover flap (32). A drainage device (41) which comprises drain grooves (42, 43) is provided in the flow channel (13), and the cover flap (32) has a hinge region which is formed by a first slot and a second H-shaped slot.
