A respiratory therapy apparatus includes components operable to simultaneously provide a High Frequency Chest Wall Oscillation (HFCWO) therapy and a Mechanical Insufflation/Exsufflation (MIE) therapy to a patient. The respiratory therapy apparatus includes a controller that controls a synchronization of the HFCWO therapy and the MIE therapy to provide respiratory therapy to the patient to effectively clear mucous or induce deep sputum from the lungs of patient.

A CPR machine (100) is configured to perform, on a patient's (182) chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A force sensing system (149) may sense a compression force, and the driving can be adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (850). An optional chest-lifting device (152) may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected.

A distension/compression device for assisting breathing in a subject in one embodiment includes a first tube includes a flexible and elastic material that forms a first tube lumen extending from a proximal end to a distal end of the first tube. Longitudinal expansion of the first tube is restricted less than radial expansion of the first tube. A connection element including a first air supply port is in fluid communication with an open proximal end of the first tube lumen and attached to a proximal end of the first tube. A method for assisting breathing of a patient and a method for assisting the clearing of secretions is also included.

A compression device may include a compression plunger in operable communication with a fulcrum assembly and housing assembly in operable communication with a stepper assembly. The compression device may be constructed and arranged to allow a user to administer CPR to a patient by stepping on a portion of the stepper assembly to generate hydraulic power that may be utilized to move the compressor plunger to apply compressive force to the patient's chest. The compression device may include a housing assembly and fulcrum assembly constructed and arranged to provide for variable height and width such that patients of varying sizes can be accommodated and may receive CPR.

A training method includes: a step of contracting a lateral abdominal muscle including a transverse abdominal muscle to pull in an abdominal periphery voluntarily by a trainee; a step of covering the abdominal periphery pulled in voluntarily by the trainee from an upper portion of a pelvis to a bottom of a tenth rib by tightly wrapping while stretching a training tool (6) in a longitudinal shape made of elastic foam having buoyant force, stretchability and flexibility; and a step of carrying out training while maintaining a state where the abdominal periphery is pulled in by shrinking force of the training tool (6).

A device for treating vascular insufficiency is described. The device includes a flexible and elastic tubular structure attached to a base layer. The flexible and elastic tubular structure include an air inlet, where longitudinal expansion of a first portion of the tubular structure is less restricted than radial expansion of the first portion of the tubular structure. A fastener is attached to the base layer and configured to fasten the base layer circumferentially around a limb. A method for treating vascular insufficiency is also described.
