Physiological data recording apparatus for single handed application
First Claim
1. A physiological data recording apparatus comprised of:
- (a) a pocket computer with display on the front, (b) one or more sensors mounted on the back of said pocket computer, (c) means to physically connect said sensors and said pocket computer, (d) means for physiological signal amplification, filtering, and transmission from said sensors to said pocket computer, whereby said apparatus can be single handedly pressed by an operator against patient'"'"'s body in such a manner that sensors are in contact with patient'"'"'s body and visual display is directed toward the operator.

Abstract
The invention disclosed herein simplifies application of physiological sensors to the body. In the preferred embodiment the plurality of physiological sensors are physically attached to the back of a personal digital assistant (PDA). An operator presses the PDA single-handedly against patient'"'"'s chest in such a manner that sensors are in contact with patient'"'"'s skin and the PDA display faces the operator. Physiological signals are then visualized on the PDA screen. The sensors include EKG electrodes and acoustic sensors. The “EKG Stethoscope” is used to simultaneously record the audio signal from an acoustic sensor and the corresponding electrical EKG signal from EKG electrodes. The PDA analyzes EKG and acoustic signals. Further, sound from one acoustic sensor is amplified and transmitted to operator'"'"'s headphones for simultaneous auscultation. Concurrent audio and visual experience greatly enhances the operator'"'"'s ability to diagnose lung and heart disease. A plurality of acoustic sensors is used to localize intrathoracic sound origin. The operator looks at the PDA display for cues on abnormal sound location and sound characteristics.
