摘要:
A nebulizer includes a body, an air channel section and medication reservoir. An air line extends through the air channel section. A venturi nozzle is configured to form at its end a low pressure mixing chamber. A primary suction line extends from the medication reservoir to the low pressure mixing chamber through which medication is drawn upward into the low pressure mixing chamber and mixed with air from the venturi nozzle and nebulized for discharge through a nebulizer outlet. The venturi nozzle, low pressure mixing chamber and air channel section are configured such that at standard temperature and pressure (STP) a differential pressure results in no medication that is drawn upward through the primary suction line for nebulization and discharged the through the nebulizer outlet until a negative inspiratory pressure is created from inhalation by a user.

In accordance with non-limiting examples, a nebulizer includes a main body comprising an air channel section and further comprising a mixing chamber and a venturi positioned to be placed within the patient's oral cavity and configured to receive medicine and air and mix the medicine and air within the mixing chamber and receive the air flow through the venturi and cause the medicine entering the mixing chamber to be atomized by the action of air flowing through the venturi. An air flow sensor is associated with the main body and configured to measure the air flow created by the patient's one of at least inhaling and exhaling air.

A system and method diagnoses esophageal reflux in a patient. A catheter includes a first pressure sensor configured to measure intra-abdominal pressure when the catheter is inserted into the stomach of a patient. A second pressure sensor is located proximal to the distal tip and configured to measure intra-thoracic pressure. A pH indicator is carried by the catheter body and configured to indicate that reflux has occurred in response to an involuntary reflex cough test. A processing device is configured to receive data regarding the first and second pressure sensors and regarding the pH indicator and process that data and assess if reflux is present during the involuntary epoch.

A system and method tests the gastric valve in a patient. A contrast agent is supplied into the stomach of the patient. An involuntary reflex cough epoch is induced within the patient to isolate the gastric valve from the lower esophageal sphincter (LES). A fluoroscopic instrument is used to detect whether stomach reflux has occurred indicative of a malfunctioning gastric valve.
