High frequency chest wall oscillation system

摘要

A high frequency chest wall oscillation (HFCWO) system (30) 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).
