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 system for accurately reproducibly positioning sensors for gathering physiological data from a subject'"'"'s body, the system comprising:

steady means for stationing in a reproducible position the subject'"'"'s body;

sensor means affixed to the steady means for taking physiological data from contact with the subject'"'"'s body; and

transfer means affixed to the steady means for transferring the subject'"'"'s body into and out of stationing within the steady means, and into and out of contact with the sensor means.

2. A system according to claim 1 wherein the steady means includes a rigid body having a negative impression of a portion of the subject'"'"'s body.

3. A system according to claim 1 wherein the transfer means includes a pair of rollers supporting a hammock.

4. A system according to claim 1 wherein the sensor means comprises a motion transducer.

5. A system according to claim 1 wherein the sensor means comprises a temperature transducer.

6. A system according to claim 1 wherein the sensor means comprises one or more electrodes.

7. A system according to claim 1 wherein the sensor means comprises a stethoscope bell.

8. A system according to claim 1 wherein the sensor menas comprises vertical force transducers.

9. A system according to claim 1 wherein the sensor means comprises a transdermal blood oxygen sensor.

10. A system according to claim 1 wherein the sensor means comprises a transdermal blood carbon dioxide sensor.

11. A physiological data acquisition apparatus for reliably repetitively reproducibly emplacing physiological sensors in precise locations contacting a body of a subject person, wherein the subject person cooperates only passively by initially deploying his/her body upon the apparatus at an imprecise position not in contact with the physiological sensors, the apparatus for acquisition of physiological data from sensors directly precisely contacting a passively cooperative subject person comprising:

a body mold of the subject person with the physiological sensors at precise locations within the cavity of the body mold;

mechanical means for initially accepting the body if the subject person at an imprecise location, and for thereafter positioning the body of the subject person within the cavity of the body mold so that the physiological sensors within the cavity are contacting the body of the subject person at precise locations thereupon.
