摘要： An oxygen concentrator comprises an oxygen reservoir and adsorbent columns that each have an inlet, an outlet, and a bed of adsorbent material. The concentrator also comprises an air inlet, an exhaust outlet, and a vacuum pump for pumping nitrogen rich gas from one of the column inlets to the exhaust outlet. A product control pump pumps oxygen rich gas from one of the column outlets to the oxygen reservoir. A control valve controls flow in and out of the columns by selectively connecting the air inlet to one column inlet, connecting the vacuum pump to another column inlet, and connecting the product control pump to a column outlet. A motor drives the vacuum pump and control valve to produce vacuum swing adsorption (VSA) cycles in which oxygen-rich product gas is separated and accumulated in the reservoir.

摘要： Concentrated oxygen product gas is produced and delivered to a patient. Product gas is produced by (a) introducing ambient air into a first end of a column containing an adsorbent material that preferentially adsorbs nitrogen and removes oxygen-rich product gas out a second end of the column; (b) evacuating the column through the first end to remove adsorbed gas from the column; (c) repressurizing the column by introducing ambient air into the first end of the column until the column is near 1.0 atmosphere; and (d) repeating steps (a)-(c). Product gas is delivered as needed to the patient.

摘要： 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.

摘要： 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.
