Latest Patents
One of Kaspari's latest patents is an apparatus and method for noninvasive blood pressure measurement. This innovative blood pressure monitor includes a processor that receives an initial input representing the patient's absolute blood pressure and a noninvasive sensor that measures various physiological functions. The processor evaluates the initial input alongside the sensed physiological data to accurately determine the patient's blood pressure. This invention also allows for the analysis and tracking of other physiological variables, such as vascular wall compliance and cardiac output.
Another notable patent is the arterial sensor, which utilizes strips of piezoelectric material to noninvasively measure the surface force and displacement caused by a blood pressure wave traveling through an artery. This sensor is designed to cancel noise artifact signals, ensuring accurate readings. The preferred embodiment features three sensing elements, with the center element positioned over the artery to capture the pressure wave, while the noise sensing elements help eliminate interference. This innovative design also includes a mechanism for maintaining appropriate pressure and a wrist stabilization device for effective monitoring.
