toSense is developing the CoVa™ Monitoring System, featuring a novel body-worn Sensor for at-home patients with chronic illnesses, such as congestive heart failure (CHF), chronic obstructive pulmonary disease, hypertension, and renal failure.
Worn like a conventional necklace for just minutes each day, the Sensor measures thoracic bioimpedance and electrocardiogram waveforms, and from these calculates a thoracic impedance, heart rate, heart rate variability, and respiration rate.
The same hardware, augmented with next-generation versions of firmware, will measure additional vital signs and hemodynamic properties such as stroke volume and cardiac output.
Electronics that measure these parameters are embedded within the Sensor, resulting in a comfortable, easy-to-use device with no external wires. The Sensor is designed for older patients, emphasizing usability with such features as a magnetic clasp to turn the Sensor on, magnetic electrodes, and simple wireless data transmission.
