Abstract
The invention provides an ultrasonic monitor for measuring pulse rate values in a living subject, including a module with at least one source of ultrasonic energy, a gel pad comprised of a polymer and from about 50 to about 95% by weight of an ultrasound conductive diluent, wherein the gel pad is positioned in direct contact between the module and the living subject; an ultrasonic energy detector and associated hardware and software for detecting, calculating and displaying a readout of the measured rate values.
Claims48
An ultrasonic monitor for measuring pulse rate values in a living subject, comprising:
- a) at least one source of ultrasonic energy;
- b) a gel pad comprised of a polymer and from about 50 to about 95% by weight of an ultrasound conductive diluent, wherein said polymer is characterized by having
- i) needle penetration from about 5 to about 300 (1/10 mm) according to ASTM D15;
- ii) tensile strength from about 5 to about 500 psi according to ASTM D412;
- and
- iii) elongation from about 50% to about 800% according to ASTM D412;
- wherein said gel pad is positioned directly between the energy source and the living subject;
- c) an ultrasonic energy detector;
- and
- d) associated hardware and software for detecting, calculating and displaying a readout of the measured rate values.
