INSUFFLATION-EXSUFFLATION SYSTEM WITH PERCUSSIVE ASSIST FOR REMOVAL OF BRONCHO-PULMONARY SECRETIONS |
摘要 |
An improved insufflation-exsufflation system with percussive assist for removal of broncho-pulmonary secretions includes a conduit for connection to a patient's airway; a pressure source for providing to the conduit alternating positive and negative pressure fluctuations at a first rate corresponding to patient insufflation-exsufflation; and a control mechanism for varying pressure during positive and negative pressure fluctuations at a second higher rate to periodically decrease the positive pressure during positive fluctuations and decrease the negative pressure during negative fluctuations to provide percussive pulses during at least one of insufflation-exsufflation to clear broncho-pulmonary secretions from the patient's airway. |
