1. A new device for monitoring one of a plurality of physiological pressures associated with a patient, the device comprising:
- a housing for protecting the device, the housing having a first planar surface adapted for placement on a patient;
at least one pressure transducer integral with the housing and adapted for placement on the patient, the at least one pressure transducer providing an output signal;
a transmitter in operative communication with the at least one pressure transducer, and operatively attached to the housing, the transmitter adapted to broadcast a signal which is modulated by an output of the at least one pressure transducer; and
a display secured to the housing and operatively connected to the at least one pressure transducer for displaying a representation of the output from the at least one pressure transducer, the display adapted for placement on the patient, a memory disposed within the housing and operatively connected to the at least one pressure transducer for storing an audio representation of the output signal;
wherein the at least one pressure transducer includes a bell portion and a diaphragm portion disposed along said first surface, and the device includes a switch for selecting either an output of the bell or the diaphragm as the output signal.

Abstract
A device and a method of sensing and transmitting physiological pressures and body temperatures are disclosed. The device includes a transducer and a transmitter. The transmitter is adapted to broadcast a signal which is modulated by the output of a transducer. The transmitter is also adapted to limit the power of the output signal. The method includes transducing a physiological parameter and broadcasting a signal which is modulated by the transduced parameter. The power of the output signal is limited so that the signal will attenuate within a predetermined distance.
