Abstract: A percussive pulsing therapy device configured for delivering pulsating or intermittent airflow to a patient device, such as a patient vest. The percussive pulsed air device may have an airflow generator for controlling amplitude of the percussive pulsed air and a pulse frequency control module for controlling frequency of the percussive pulsed air. In some embodiments, the pulse frequency control module may have a rotatable fan blade, such as a circular fan blade having one or more cutout portions. In some embodiments, the rotating fan blade may have one or more channels configured to redirect percussive pulsed air. Moreover, a percussive pulsed air device of the present disclosure may have a dampening element flowably coupled to an inlet of the pulse frequency control module. In some embodiments, at least one inlets of the pulse frequency control module may be arranged on a different airflow plane than one or more outlets.

Abstract: The present disclosure relates to devices, systems and methods for improving patient adherence with respect to HFCC therapy. A therapy system of the present disclosure may include a percussive pulsing therapy device configured for delivering pulsating or intermittent airflow to a patient device, such as a patient vest worn by a patient. The airflow delivered to the patient vest may have an air pressure and a frequency, each of which may be adjustable in some embodiments. A therapy system of the present disclosure may additionally include a controller, a database, and one or more sensors. The controller and/or one or more sensors may record therapy data for a therapy session. Based on the recorded therapy data, the system may provide encouragement, advice, motivation, and/or options or information to a user by way of skills training, goal setting, feedback, reinforcement, environmental prompts, social support, and/or other patient interventions.

Abstract: In a convective system that includes a blower to thermally treat and pressurize air, a convective device to receive and convect the thermally-treated pressurized air, and an air hose to conduct a flow of thermally-treated pressurized air from the blower to an inlet port in the convective device, an interface device is provided to control the flow of air at the interface where the inlet port and an end of the air hose operate to conduct the flow of air out of the air hose into the convective device. The interface device is received at the end of the air hose and operates to support the flow of air out of the end when the end and the inlet port are brought together. The interface device operates to stop, inhibit, or restrict the flow of air out of the end when the end and the inlet port are separated.

Abstract: A propulsion system and pump having inner and outer chambers. The outer chamber is formed by a rigid outer shell and a pair of spaced apart end plate assemblies. The inner chamber is located concentrically within the outer chamber and between the spaced apart end plate assemblies. Each end plate assembly has a drive member. Each drive member has a plurality of arcuate openings extending radially and tangentially outwardly from the center. The outer chamber has at least one outer chamber intake valve located on the one end plate assembly and at least one outer chamber discharge valve located on the other end plate assembly. The inner chamber has at least one inner chamber intake valve located on one end plate assembly and at least one inner chamber exhaust valve located on the other end plate assembly. The inner chamber is formed from a plurality of elongated, overlapping, v-shaped plate members longitudinally aligned between the first and second end plate assemblies.
