Efficient high-frequency chest wall oscillation system

摘要

PROBLEM TO BE SOLVED: To provide a high frequency chest wall oscillation (HFCWO) system for avoiding dependence on a care giver who executes physiotherapy, although percussion technique using a hand in the chest physiotherapy is conventionally used for removing excess mucus accumulated in the lungs.;SOLUTION: The high frequency chest wall oscillation (HFCWO) system comprises an air pulse generator 100 having a blower inlet 158 in communication with a blower 36 and an air port 160 in communication with an inflatable garment 42. The air pulse generator 100 comprises a housing 102 and an air pulse assembly coupled to the housing 102. The air pulse assembly has at least one diaphragm 144, 146, at least one driver 164, 166 operable to move the at least one diaphragm 144, 146 and at least one spring 168 arranged to bias the at least one diaphragm 144, 146 away from a portion 104, 106 of the housing 102.;COPYRIGHT: (C)2008,JPO&INPIT
