Abstract

Disclosed is a system, apparatus and method for gathering physiological data. Basic to the system of the present invention is a rigid body mold having preferably a negative impression of the dorsal half of the body. By connecting and/or embedding sensors to the body mold at specific locations, e.g., accelerometers, thermistors, and electrocardiogram electrodes, the sensors will be accurately and reproducibly positioned next to a specific body location each time the subject lies in the body mold. The body mold can be used to insulate the body from external motions thereby facilitating the preparation of a ballistocardiogram. The exact re-positioning of the body in the mold allows exact determination of the center of gravity in the horizontal plane of the body.

Claims

1. A method for monitoring a subject'"'"'s heart and lung sounds comprising the steps of:

providing a rigid body mold having an impression intimately matching the entire length of the dorsal portion of the subject'"'"'s body and embedding in the mold sensor means for obtaining heart and lung sounds and producing an output corresponding to such sounds;

placing the subject in a supine position in the body mold so that the subject'"'"'s heart and lung sounds can be received by the sensor means, whereby the subject'"'"'s body comes into contact with said sensor means; and

checking the resulting sensor output.

2. The method of claim 1 wherein said step of placing comprises frrst placing the subject on a thin, flexible sheet, and then lowering the sheet bearing the subject into the impression, whereby the subject'"'"'s body comes into contact with said sensor means through said sheet.

3. The method of claim 1 further comprising the step of listening to the sensor output.
