Patent number: 8038633Abstract: An air pulse generator for providing high frequency chest wall oscillation therapy to a patient is provided. The air pulse generator has a housing and first and second diaphragms supported in the housing. The air pulse generator further has a crankshaft assembly coupled to the first and second diaphragms to reciprocally move the diaphragms back and forth to produce oscillating pressure pulses. The crank shaft assembly includes a motor with an output shaft that rotates about a first axis, a flywheel mounted on the shaft to rotate therewith, a first member coupled to the first diaphragm and pinned to the flywheel by a first stub shaft that is offset from the first axis, a second member coupled to the second diaphragm, and a cam interposed between the first member and the second member. The first member is pinned to the cam by the first stub shaft and the second member is pinned to the cam by a second stub shaft.Type: GrantFiled: September 28, 2009Date of Patent: October 18, 2011Assignee: Hill-Rom Services Pte. Ltd.Inventors: Nicholas P. Van Brunt, John A. Kivisto, Donald J. Gagne

Patent number: 7018348Abstract: An apparatus for inducing sputum samples for diagnosing pulmonary disorders, especially as it relates to detection of early stages of lung cancer. The apparatus is comprised of a pneumatic chest compression vest, a pneumatic pressure generator, and a mouthpiece connected to a nebulizer. Sputum samples are induced by applying an oscillating force to the chest via the pneumatic chest compression vest and pressure generator, while simultaneously providing an aerosolized solution (such as normal or hypertonic saline) via the nebulizer while the patient is standing. The sample is subsequently evaluated to ascertain a patient's risk of or the presence of a pulmonary disorder such as lung cancer.Type: GrantFiled: February 25, 2002Date of Patent: March 28, 2006Assignee: Hill-Rom Services, Inc.Inventors: Nicholas P. Van Brunt, Donald J. Gagne
