Patient position detection system

Abstract

A patient movement detector can receive inputs from position sensors, a thermal imaging camera, a video camera, and/or triangulation data. Based on one or more of these inputs, the patient movement detector can perform one or more of the following: fall prevention detection, bedsore prevention analysis, patient location detection, and patient walk test scoring. The patient movement detector can, for example, output a fall warning alarm, a bedsore warning alarm, patient location information, and walk test scores.

What is claimed is: 
     
         1 . (canceled) 
     
     
         2 . A patient-worn monitoring system comprising:
 a patient monitor configured to be worn by a patient;   an electrocardiograph (“ECG”) sensor in communication with the patient monitor and configured to be worn by the patient and obtain physiological information of the patient; and   a motion measurement device in communication with the patient monitor and configured to obtain motion, movement, and/or position data of the patient,   wherein the patient monitor includes one or more hardware processors configured to: 
 determine, based at least in part on a combination of the physiological information and the motion, movement, and/or position data, a physiological parameter of the patient. 
   
     
     
         3 . The patient-worn monitoring system of  claim 2 , wherein the motion measurement device includes at least one of: an accelerometer, or a gyroscope. 
     
     
         4 . The patient-worn monitoring system of  claim 2 , wherein the motion measurement device is included in the patient monitor. 
     
     
         5 . The patient-worn monitoring system of  claim 2 , wherein the motion measurement device is included in the ECG sensor. 
     
     
         6 . The patient-worn monitoring system of  claim 2 , wherein the motion measurement device is included in another sensor that is in communication with the patient monitor. 
     
     
         7 . The patient-worn monitoring system of  claim 2 , wherein the ECG sensor is in wired communication with the patient monitor. 
     
     
         8 . The patient-worn monitoring system of  claim 2 , wherein the patient monitor is further configured to wirelessly communicate the physiological parameter to a bedside monitor. 
     
     
         9 . The patient-worn monitoring system of  claim 2  further comprising:
 an optical sensor in communication with the patient monitor and configured to be worn by the patient and obtain additional physiological information of the patient, 
 wherein the one or more hardware processors are further configured to:
 determine, based at least in part on a combination of the additional physiological information and the motion, movement, and/or position data, an additional physiological parameter of the patient. 
 
 
     
     
         10 . The patient-worn monitoring system of  claim 9 , wherein the motion measurement device includes at least one of: an accelerometer, or a gyroscope. 
     
     
         11 . The patient-worn monitoring system of  claim 9 , wherein the motion measurement device is included in the patient monitor. 
     
     
         12 . The patient-worn monitoring system of  claim 9 , wherein the motion measurement device is included in the ECG sensor. 
     
     
         13 . The patient-worn monitoring system of  claim 9 , wherein the motion measurement device is included in the optical sensor. 
     
     
         14 . The patient-worn monitoring system of  claim 9 , wherein the motion measurement device is included in another sensor that is in communication with the patient monitor. 
     
     
         15 . The patient-worn monitoring system of  claim 9 , wherein the ECG sensor is in wired communication with the patient monitor. 
     
     
         16 . The patient-worn monitoring system of  claim 9 , wherein the optical sensor is in wired communication with the patient monitor. 
     
     
         17 . The patient-worn monitoring system of  claim 9 , wherein the patient monitor is further configured to wirelessly communicate the physiological parameter and the additional physiological parameter to a bedside monitor.
