iSonea of Millersville, Maryland has announced that its cough counting technology received a patent from the United States Patent and Trademark Office.
The company’s products, like the pictured Wheezometer, use Acoustic Respiratory Monitoring (ARM) to detect wheezes, rhonchi and coughs.
From the press release:
Leveraging the company’s proprietary Acoustic Respiratory Monitoring™ (ARM) technology, the patent covers the ultrasound-based cough detector that fits against a patient’s neck and automatically detects coughs and counts coughing events. The sensors on the device can detect high and low frequency mechanical vibrations in the tracheal area. The device senses coughing events, tracks their severity and duration, and stores that data or sends it wirelessly to a computer or other log.
