Abstract

Devices, systems, and methods for HFCWO oscillation therapy can enhance expectoration by preferred impact to the user to encourage mucus dislodging, including by successive pressure imposition to a chest engagement device to provide HFCWO.

First claim

We claim:

1 . A chest wall oscillation therapy system, comprising:
a chest engagement device for communicating impact force to a patient's chest; a force generator arranged to generate successive force of impact as a therapy regime for the patient, the force generator arranged in communication with the chest engagement device to communicate force of impact from the force generator into impact force to the patient's chest to encourage airway clearance, and a therapy control system comprising at least one sensor arranged to detect an indication of a breathing pattern of the patient, wherein the therapy control system is arranged to dynamically configure the therapy regime of the force generator according to data from the at least one sensor including, for each cycle of inhalation and exhalation of the patient, to decrease an oscillation rate of the impact force while the patient inhales, and then, in response to cessation of inhalation, to increase the oscillation rate of the impact force while the patient exhales, wherein active therapy of the therapy regime continues for at least a portion of time while the patient inhales to communicate impact force during inhalation, wherein the therapy control system configures the therapy force generator to have an inhalation setting for the oscillation rate during patient inhalation, the inhalation setting being less than an exhalation setting for the oscillation rate during patient exhalation such that the patient experiences lesser time of force of impact during patient inhalation than during patient exhalation.

2 . The chest wall oscillation therapy system of claim 1 , wherein the at least one sensor comprises at least one micro electromechanical sensors.

3 . The chest wall oscillation therapy system of claim 2 , wherein the at least one sensor is mounted to the chest engagement device to detect motion of the patient's chest.

4 . The chest wall oscillation therapy system of claim 1 , wherein the at least one sensor is arranged to provide at least nine-axis tracking of chest movement of the patient.

5 . The chest wall oscillation therapy system of claim 1 , wherein the at least one sensor comprises at least one accelerometer.

6 . The chest wall oscillation therapy system of claim 1 , wherein the at least one sensor comprises at least one gyroscope.

7 . The chest wall oscillation therapy system of claim 1 , wherein the at least one sensor comprises at least one magnetometer.

8 . The chest wall oscillation therapy system of claim 1 , wherein the therapy control system includes at least one processor for providing construction of motion based on data received from the at least one sensor.

9 . The chest wall oscillation therapy system of claim 1 , wherein the therapy control system is arranged in communication with a personal mobile device to communicate indication of the patient's chest.

10 . The chest wall oscillation therapy system of claim 1 , wherein the therapy control system includes a graphical user interface for communicating with a user.

11 . The chest wall oscillation therapy system of claim 10 , wherein the graphical user interface is arranged to present selectable options for user selection.

12 . The chest wall oscillation therapy system of claim 11 , wherein the selectable options for user selection include an oscillation start button for initiating operation to provide impact force to the patient.

13 . The chest wall oscillation therapy system of claim 12 , wherein responsive to user selection of the oscillation start button, the graphical user interface presents a pause button.

14 . The chest wall oscillation therapy system of claim 12 , wherein the selectable options for user selection include a new predetermined therapy regime button for user creation of a new predetermined therapy regime for implementation as the therapy regime.

15 . The chest wall oscillation therapy system of claim 14 , wherein the new predetermined therapy regime button is accessible by user activation of a pull tab for expansion.

16 . The chest wall oscillation therapy system of claim 12 , wherein the selectable options for user selection include an unlock button, wherein responsive to user selection of the unlock button at least one of frequency, intensity, and time buttons are presented as selectable options for user selection to configure corresponding features.

17 . The chest wall oscillation therapy system of claim 16 , wherein user activation of the unlock button includes dragging the unlock button to a predetermined extent.

18 . The chest wall oscillation therapy system of claim 17 , wherein the therapy control system includes a garment size toggle switch operable for user selection between an on position in which the therapy control system adapts configuration of the force generator to account for the size of the wearable garment, and an off position in which the therapy control system does not adapt configuration of the force generator to account for the size of the wearable garment.

19 . The chest wall oscillation therapy system of claim 12 , wherein the selectable options for user selection include a predetermined therapy regime tab for implementing a predetermined therapy regime as the therapy regime.

20 . The chest wall oscillation therapy system of claim 19 , wherein responsive to user selection of at least one of the predetermined therapy regime tab and an unlock button, a cough pause tab is presented for user selection to configure cough pause settings of the predetermined therapy regime.

21 . The chest wall oscillation therapy system of claim 20 , wherein responsive to user selection of the cough pause tab at least one of a cough pause enable switch and auto-restart switch is presented for user selection.

22 . The chest wall oscillation therapy system of claim 21 , wherein responsive to user selection of the cough pause enable switch to affirm cough pause, at least one of a pause duration and pause frequency button are presented for user selection to adjust corresponding features.

23 . The chest wall oscillation therapy system of claim 11 , the selectable options include a pull tab for user activation to present additional selectable options, wherein the additional selectable options include at least one of a home button, a cough pause settings button, and a delete therapy button.

24 . The chest wall oscillation therapy system of claim 1 , wherein the chest engagement device comprises a wearable garment.

25 . The chest wall oscillation therapy system of claim 1 , wherein the therapy control system configures the therapy force generator to have an exhalation setting for at least one of the oscillation rate and an intensity of the impact force during patient exhalation, the exhalation setting being greater than a predetermined nominal setting for the at least one of the oscillation frequency and the intensity of the impact force.

26 . The chest wall oscillation therapy system of claim 1 , wherein the therapy control system configures the therapy force generator to have an inhalation setting for the intensity of the impact force during patient inhalation, the inhalation setting being less than the exhalation setting during patient exhalation.

27 . The chest wall oscillation therapy system of claim 26 , wherein the inhalation setting is less than or equal to the predetermined nominal setting.
