摘要:
A system and method diagnoses esophageal reflux in a patient. A catheter (1500) includes a first pressure sensor (1510) configured to measure intra-abdominal pressure when the catheter is inserted into the stomach of a patient. A second pressure sensor (1512) is located proximal to the distal tip and configured to measure intra-thoracic pressure. A pH indicator (1520) 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 nasogastric/orogastric (Ng/Og) airway protection device includes an elongate device body having a distal end for insertion into the stomach through the esophagus and a proximal end. A main lumen extends the length of the device and is configured for at least one of gastric decompression, enteral feeding and enteral medication administration. A sump port is at the distal end. A sump lumen is formed the length of the device body and configured for venting gas and preventing adherence of the device against the gastric wall. An inflatable esophageal cuff is carried by the device body mid-esophagus and an inflation lumen is formed within the device body and connects the inflatable esophageal cuff through which the esophageal cuff is inflated and deflated. Upon inflation of the esophageal cuff, emesis and/or reflux is blocked from passing out of the stomach past the esophageal cuff positioned mid-esophagus to protect a patient's airway.

An apparatus and method for evaluating a patient's laryngeal cough reflex function includes a nebulizer capable of being actuated to atomize a cough-inducing substance, a switch associated with the nebulizer, the switch responsive to actuation of the nebulizer, and a connection between the switch and an EMG machine to thereby activate the EMG machine responsive to the switch. Elapsed time between switch actuation and electrical activity sensed in a muscle which contracts to produce a cough is indicative of status of the patient's laryngeal cough reflex.

A nebulizer includes a body (50) having an air channel section, medication reservoir (58) and nebulizer outlet (60) configured to be received within an oral cavity of a patient. A nebulizer suction member encloses the body and is configured as an infant pacifier. An air line (66) extends through the air channel section and has a venturi nozzle (52) and at its end configured to form 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 and mixed with air passing through the venturi nozzle and nebulized for discharge through the nebulizer outlet.

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.
摘要:
Techniques for detecting stress urinary incontinence use a pressure sensing catheter the electrical indications of which are applied to a processing unit for detecting pressure levels generated during involuntary coughs. The involuntary coughs are induced preferentially by using a nebulized composition of L-tartrate in a pharmaceutically acceptable carrier. The area under the curve generated from pressure samples is calculated and used in conjunction with the detection of urine leakage to determine the existence of stress urinary incontinence.
