COORDINATED CONTROL OF HFCWO AND COUGH ASSIST DEVICES

摘要

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.

主权项

1. A respiratory therapy apparatus comprising
a housing; a high frequency chest wall oscillator (HFCWO) supported in the housing and operationally coupled to a garment worn on a torso of a patient to deliver a HFCWO therapy to the patient, the HFCWO therapy comprising application to the garment of a first baseline positive pressure and pressure oscillations relative to the first baseline positive pressure; a mechanical insufflator/exsufflator (MIE) supported in the housing and coupled to the patient's airway via a patient interface to deliver MIE therapy to the patient, the MIE therapy comprising cycles of a positive insufflation pressure and a negative exsufflation pressure applied to the patient's airway via the patient interface; and a controller situated in the housing and operable to control the HFCWO therapy and the MIE therapy, wherein during application of the negative exsufflation pressure to the patient's airway, the controller signals the HFCWO to apply a second baseline positive pressure to the garment thereby to provide an extra squeeze to the patient's torso during application of the negative exsufflation pressure to the patient's airway.
