KarmelSonix Selects Technology Of Analog Devices

For asthma management

Analog Devices has reported that KarmelSonix has chosen its (Analog Devices) Blackfin digital signal processors and advanced signal chain components to power its products for asthma management.

overnight pulmonary monitor, and the Wheezometer, a personal asthmatic assessment device, address the critical need of over 300 million asthma sufferers worldwide and over 50 million people in G7 countries alone, said the company.

The devices are designed to self-assess and manage the threatening asthma symptoms a capability previously available only at clinicians’ offices or hospitals, said the company.

The company claims that Blackfin BF525-based Wheezometer, a hand held, mobile device acquires real-time data from sensors attached to the patient’s body, then stores, processes and displays the results as a ‘wheeze rate’ level. This capability is facilitated by a proprietary noninvasive piezoelectric sensor array that enables detection, through sensitive breath sound analysis, of respiratory wheezing (stridor), shows powerful performance and mobile precision.

Reportedly, the Blackfin BF524-based Wholter includes an on-person monitoring device which monitors wheeze activity over an extended period of time for at-home pulmonary diagnostics. The Wholter records continual breathing effort and heart rate from two phonopneumography (PPG) sensors and then digitally stores the data on the device’s flash memory for a 24-hour time period.

After the recording period, the processed data is then uploaded to the physician’s system for diagnosis. Therefore it exhibits continuous real-time data capture and signal processing, said the company.
