A high frequency chest wall oscillation therapy system includes an air pulse generator. The air pulse generator includes control circuitry and a fluid chamber carrying a fluid. A motor is configured to generate compression and expansion of the fluid in the fluid chamber to generate pressurized fluid. A pressure sensor detects a pressure of the pressurized fluid in the fluid chamber. A garment includes at least one fluid bladder defining a pressurizable chamber adapted to receive the pressurized fluid from the fluid chamber to provide a force of high frequency pressure oscillation to a patient's chest wall.

A gastrointestinal treatment system including a gastrointestinal capsule adapted to treat a subject following ingestion of the gastrointestinal capsule. The gastrointestinal capsule includes: (a) a housing; (b) a vibrating agitator, powered by the battery, the vibrating agitator adapted such that, in a first vibrating mode of operation, the housing exerts vibrations on an environment surrounding the capsule; (c) a power supply disposed within the housing and adapted to power the vibrating agitator; and (d) a controller adapted, in response to receipt of an activation input, to activate the vibrating agitator to operate in the first vibrating mode of operation at at least one predetermined time of day. The system and method may be used to treat an ailment of the gastrointestinal tract and/or to mitigate at least one symptom of jetlag in a subject travelling from an origin location to a destination location.

A motor is configured to generate compression and expansion of the fluid in the fluid chamber to generate pressurized fluid. A garment includes at least one fluid bladder defining a pressurizable chamber adapted to receive the pressurized fluid from the fluid chamber to provide a force of high frequency pressure oscillation to a patient's chest wall. A pressure sensor detects a pressure relating to the pressurized fluid in the fluid chamber. The control circuitry generates a pressure signal based on the pressure detected.

A medical device system including a wearable harness worn, during use, on a torso of a subject. Engines coupled to the wearable harness apply an oscillation force to at least one treatment area of the subject in order to mobilize at least some secretions in an airway within the subject substantially adjacent to the at least one treatment area. The wearable harness is secured on the subject using one or more straps coupled to the wearable harness. A controller determines a tension force applied by at least one of the straps by receiving measurements of at least one property from a force sensing element (e.g., a force sensor) integrated with the strap. The tension force may also be correlated to forces being applied to the subject by the engines.

The present disclosure relates to the technical field of assistive rehabilitation equipment, specifically to a cardiac rehabilitation assistive therapy device. The device comprises an exercise assistance mechanism configured to assist a patient in performing reciprocal waist twisting exercises, wherein the exercise assistance mechanism comprises a turntable. In the present disclosure, when pressure applied by the pressure springs to a bottom one of the second piston disks decreases, resistance encountered by the patient during waist twisting reduces accordingly. As the square tube communicates with the four-way shell through a hose, when hydraulic pressure in the four-way shell decreases, a height of the rubber plate also decreases. Consequently, abutment force between the friction plate and the rubber plate diminishes, thereby reducing resistance encountered by the patient during knee flexion exercises. Thus, upon detecting increased heart rate of the patient via the heart rate belt, the device will reduce movement resistance correspondingly.
