| 20110066004 | PASSIVE PHYSIOLOGICAL MONITORING (P2M) SYSTEM - Passive physiological monitoring apparatus and method has a sensor for sensing physiological phenomenon. A converter converts sensed data into electrical signals and a computer receives and computes the signals and outputs computed data for real-time interactive display. The sensor is a piezoelectric film of polyvinylidene fluoride. A band-pass filter filters out noise and isolates the signals to reflect data from the body. A pre-amplifier amplifies signals. Signals detected include mechanical, thermal and acoustic signatures reflecting cardiac output, cardiac function, internal bleeding, respiratory, pulse, apnea, and temperature. A pad may incorporate the PVDF film and may be fluid-filled. The film converts mechanical energy into analog voltage signals. Analog signals are fed through the band-pass filter and the amplifier. A converter converts the analog signals to digital signals. A Fourier transform routine is used to transform into the frequency domain. A microcomputer is used for recording, analyzing and displaying data for on-line assessment and for providing realtime response. A radio-frequency filter may be connected to a cable and the film for transferring signals from the film through the cable. The sensor may be an array provided in a MEDEVAC litter or other device for measuring acoustic and hydraulic signals from the body of a patient for field monitoring, hospital monitoring, transport monitoring, home, remote monitoring. | 03-17-2011 |
| 20110001622 | METHOD AND SYSTEM FOR INTEGRATING A PASSIVE SENSOR ARRAY WITH A MATTRESS FOR PATIENT MONITORING - A system is provided for integrating a passive sensor or sensor array into a patient's mattress to support continuous passive monitoring of a patients' physiological conditions in a hospital setting. The sensor or sensor array may be incorporated into the mattress by fixing it to a coverlet that surrounds the mattress, or by embedding it within the mattress core. Alternatively, the sensor or sensor array may be fixed to an underlayer positioned between the mattress core and the coverlet. | 01-06-2011 |
| 20100052917 | SYSTEMS AND METHODS FOR INTELLIGENT MEDICAL VIGILANCE WITH ALERT CAUSE INDICATION - An intelligent medical vigilance system that observes and analyzes, and, only in the event of a clinically significant negative condition, notifies and reports the event to the care staff utilizing the hospital's existing nurse call system. The device includes a bedside unit connected to a pad or coverlet with a sensor array (placed under the patient) and also to an existing hospital nurse call system via an interface. Within the physical bedside unit are a signal processor and an alarm processor that measure data and evaluate whether a clinically significant event is occurring. The bedside unit is a wall-mounted unit with a display that becomes active when an alarm condition is enabled. The sensing pad or coverlet is a thin, piezoelectric film, or other similar sensing technology, with an array of sensors sheathed in soft padding and is not directly in contact with the skin of the patient. The nurse call feature is made up of hardware, software and cabling to connect to the nurse call system already installed in the hospital or care facility. The monitoring system can also be installed in vehicles to monitor operator physiological conditions. Vigilance alarms are suspended if a patient is detected out of bed. An unable-to-measure alert is provided if the system is unable to reliably monitor. Bed exit alarms can be placed into a pause mode for supervised bed exit of patients on bed restriction. An alert message is generated and maintained on the display screen to inform a responding caregiver of the time and reason for any alarm. | 03-04-2010 |
