Problems solved by technology

Second, the soft gels of these known methods are difficult to handle
Third, the gels of the known prior art systems tend to collect dirt
This reduces crosstalk between transducers to some degree, but does not eliminate loading or damping effects caused by the backplane

Embodiment Construction

[0055] In summary, the present invention relates to ultrasonic monitors. The ultrasonic monitor uses ultrasonic signals to measure the movement inside the body of a living subject. The movement may be the contraction of the heartbeat, the movement of blood or the movement of the blood vessel itself. Based on the information collected from these exercises, the electronic components in the monitor can determine the blood flow rate, heart rate, or pulse rate of the living subject.

[0056] In one embodiment, the ultrasound monitor measures blood flow through the arteries of the human body. The frequency range of the reflected ultrasound signal due to blood vessel dilation (expansion due to the movement of blood through the vessel) is similar to the frequency range of noise due to myoelectric artifacts and tissue movement. The frequency range of the ultrasound signal reflected by the flowing blood itself is higher than the frequency range of noise related to muscles and tissues. There...

Abstract

An ultrasonic monitor implemented on a PCB includes a gel pad comprised of a gel layer and a membrane layer. Ultrasonic signals are transmitted between the ultrasonic monitor and a living subject through the gel pad. An air gap is formed in the PCB underneath transducer elements to provide for more efficient signal transmission. These features provide for a low power, low cost, more efficient ultrasonic monitor. The entire ultrasonic monitor may be encapsulated in plastic, a gel, or both to provide water resistant properties.
