System, with sensor positioning indicator, for monitoring a biological signal
First Claim
1. A system for monitoring a biological signal, representative of a physiological characteristic, from a living body, the system being of the type including sensing means, positionable on the living body, for sensing the biological signal and for generating an electrical signal representative of the biological signal;
- and processing means, coupled to said sensing means, for processing said electrical signal;
said system further comprising;
indicator means, spatially fixed relative to and within the view of said sensing means, for indicating whether said sensing means is sensing the biological signal as the sensing means is moved relative to and positioned on the living body.

Abstract
The invention is a physiological monitor for determining a physiological characteristic of a patient. The monitor is particularly adapted to monitor fetal heart rate, and includes a transducer for receiving a signal from the patient that is indicative of the physiological characteristic and for generating an output signal that is representative of the received signal. The monitor further includes a processor coupled to the transducer for receiving the output signal and generating therefrom a physiological signal that is representative of the physiological characteristic. The physiological signal may further be representative of the signal strength of a signal used to calculate the physiological characteristic. The monitor further includes a display unit fixed to the transducer and coupled to the processor for generating a display representative of the physiological signal.

17. An ultrasound fetal monitor for determining the heart rate of a fetus that is within a mother'"'"'s body, said monitor comprising:
-
a transducer unit, positioned on the mother'"'"'s body, for generating an ultrasound signal into the mother'"'"'s body and for generating an output signal representative of an ultrasound signal reflected by the fetus and received by the transducer unit in response thereto, the received ultrasound signal being representative of the heart beat of the fetus; a processor, coupled to the transducer unit for receiving the output signal and for processing the output signal so as to generate a indicator signal indicative of whether the heart rate of the fetus has been measured; and display means fixed to the transducer unit and coupled to the processor for generating a display on said transducer unit representative of the indicator signal.
