Embodiment Construction

[0119] As shown in FIG. 1, the Life Signs Detection System (LSDS) is an apparatus containing a group of sensors for certain vital physical parameters of a subject person and electronics to receive and interpret electrical signals from the sensors, process the signals and transmit information on the physical status of the subject. The group of sensors and electronics is embodied in a carrier 1 arranged to be worn by the subject. The electronics residing on a PC board is designed to accomplish most signal processing at the location of the subject and to avoid the need for robust networking and centralized computing that require large amounts of bandwidth to transmit raw signals for analysis. Such large bandwidth is impractical in field settings where bandwidth is low, unreliable and localized responsiveness must be maintained.

[0120] The carrier comprises three main elements—a central housing 3, two flexible extensions 5 containing external sensors 7 (see FIG. 2), and a harness 9. FIG...

Abstract

A wearable platform embodied in a belt or flattened patch-like central body shaped to conform to the abdomen provides physiological monitoring of soldiers during field operations or trauma victims at accident sites and makes health state assessments. The platform includes sensors for heart rate, body motion, respiration rate and intensity, and temperature and further contains a microprocessor and short range transmitter. The respiration sensor uses conductive ink in a novel manner. A small square of the ink is coated on an arched structure so that flexing of the arch either to increase or decrease its radius of curvature modifies the resistance of the structure. This is utilized to set the unstressed resistance of the arch structure and to allow a greater range of resistance values capable of measuring distortions in different deformations of the arch. The respiration sensor supplements the motion information provided by an accelerometer sensor.

Description

[0001] This patent claims the benefit of the priority of Provisional Patent Application 60 / 517,149, filed Nov. 4, 2003 and entitled “Life Sign Detection and Health State Assessment System”, the full disclosure of which is incorporated by reference.FIELD OF THE INVENTION [0002] This invention relates to compact wearable systems for measuring a subjects vital signs, such as respiration rate and motion, processing those measurements and transmitting the results of the processing wirelessly for remote monitoring. It also relates to specific sensor transducers and processing algorithms for generating electrical signals indicating vital signs, and more generally for developing diagnostic information from groups of sensor readings. BACKGROUND OF THE INVENTION [0003] Electronic devices for monitoring a patient's vital signs at bedside are in common use in hospitals. Typically these measure, display and transmit to nursing stations EKG traces, blood pressure values, body temperature values, ...
