Abstract

A manual inexsufflator including a standard mechanical ventilator, a medical suction unit, and a piston-like sliding valve mechanism which connects a patient ventilation interface with either the ventilator or the suction unit. By sliding the valve mechanism in and out the user selectively connects the patient to either the ventilator, for purposes of insufflation, or the suction unit, for purposes of exsufflation. The ventilator may generate expiratory positive airway pressure between inexsufflation cycles.

Description

CROSS-REFERENCE TO PREVIOUS APPLICATIONS

[0001] This application is a continuation-in-part application of and claims priority from U.S. patent Application Ser. No. 09 / 975,943, filed Oct. 15, 2001.FIELD OF THE INVENTION

[0002] The present invention relates generally to respiratory apparatus, and particularly to an inexsufflator useful, for example, in clearing respiratory secretions from airways. BACKGROUND OF THE INVENTION

[0003] Patients suffering from weakness of the muscles of the thoracic cage and diaphragm, as may occur in, for example, Duchenne Muscular Dystrophy or Cervical Spine Injury, are often unable to cough effectively, if at all. Due to their inability to clear respiratory secretions from their lower respiratory tract, retained secretions may develop in their lungs. As retained secretions constitute a focus for infection, these patients are at high risk of developing severe, and potentially fatal, pneumonia, and are thus in need of assistance in expectorating their res...
