Vascular testing system
First Claim
1. A vascular sensing system comprising:
- blood flow restricting means for placement on a human toe having a blood vessel, wherein the blood flow restricting means is capable of manipulating the blood vessel;
a display for indicating vascular test locations, wherein a first vascular test location is indicated as the human toe;
a pressure sensor operably connected to the blood flow restricting means and physically spaced from the blood flow restricting means for producing a sensor signal as a function of pressure at the blood flow restricting means;
means for determining a return of blood flow pressure at the first vascular test location after the blood vessel has been temporarily collapsed by the blood flow restricting means based upon the sensor signal;
means for producing an output representing the return of blood flow pressure at the first vascular location.

Abstract
A vascular sensing system includes blood flow restricting means, a sensor, and means for producing an output representing a return of blood flow after the blood vessel has been temporarily collapsed by the blood flow restricting means. The blood flow restricting means is capable of placement on a human toe having a blood vessel, and is capable of manipulating the blood vessel. The sensor is operably connected to the blood flow restricting means and is physically spaced from the toe. Further, a method of vascular sensing includes taking pressure measurements with an pressure cuff positioned on a toe, and conducting a waveform analysis of the pressure measurements to determine a return of blood flow pressure.
