Devices And Methods For Passive Patient Monitoring

US Patent:
2004011, Jun 10, 2004
Filed:
Nov 20, 2002
Appl. No.:
10/301524
Inventors:
Patrick Sullivan - Kailua HI, US
Ken Cheung - Kailua HI, US
Christopher Sullivan - Kailua HI, US
Scott Christensen - Danville CA, US
Mike Rosenman - Honolulu HI, US
Assignee:
Hoana Technologies, Inc. - Honolulu HI
International Classification:
A61B005/103
US Classification:
600/595000
Abstract:
Devices, systems and methods provide passive patient monitoring of such parameters as body motion, body position, respiratory rate and/or heart rate. Passive monitoring generally involves a sensor device having at least two piezoelectric sensors, provided on a surface, such as a bed, chair, operating table or the like, so that a patient may be coupled with the device by simply allowing the patient to lie, sit, lean, stand on or wear the surface. In one embodiment, multiple patients in a general care area of a hospital may be continuously monitored via multiple passive monitoring devices. If a patient fails to meet one or more predefined threshold criteria or has a negative physiological trend, the system may activate an alarm.

Passive Physiological Monitoring (P2M) System

US Patent:
2006006, Mar 23, 2006
Filed:
Jun 24, 2005
Appl. No.:
11/165735
Inventors:
Patrick Sullivan - Honolulu HI, US
Ken Cheung - Honolulu HI, US
Christopher Sullivan - Honolulu HI, US
International Classification:
A61B 5/00
A61B 5/02
US Classification:
600301000, 600481000
Abstract:
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.
