Abstract
This invention relates to a treatment device () and method of use, and in particular to a treatment device adapted to assist the clearance of bronchial secretions in persons whose cough function is impaired. The invention provides a treatment device having a pump () with a negative pressure inlet side () and a positive pressure outlet side (). The device has a breathing tube () for connection to a patient, and a pressure sensor () adapted to determine the pressure within the breathing tube. A valve () selectively connects the breathing tube to the inlet side or the outlet side of the pump whereby to provide cycles of positive and negative pressure within the breathing tube. A controller () is provided to control the valve. An indicator () alerts the patient to an operational status of the device so that the patient can breathe in time with the device and in particular can seek to cough at the same time as the pressure within the breathing tube is rapidly reduced.
