Multiple Mode, Portable Patient Monitoring System
The specification discloses a number of embodiments directed to patient monitoring systems. The system determines a physiological parameter of a patient and includes an input device for receiving a plurality of physical inputs from a user, such as finger taps, and communicating to a memory interval data indicative of the frequency at which the plurality of physical inputs are received from the user within a time period and a processor in data communication with said memory wherein said processor determines at least one physiological parameter of a patient based upon said interval data.
1 . A system for determining a physiological parameter of a patient, the system comprising:
an input device for receiving a plurality of physical inputs from a user and communicating to a memory data indicative of the frequency at which said plurality of physical inputs are received from the user within a time period; and
a processor in data communication with said memory wherein said processor determines the value of a physiological parameter based upon said data.
2 . The system of claim 1 , wherein said data collected by the device represents the time of each physical input by said user.
3 . The system of claim 1 wherein said physiological parameter is respiratory rate.
4 . The system of claim 1 wherein said physiological parameter is at least one of pulse rate or respiratory rate.
5 . The system of claim 1 wherein the input device is a touch screen display.
6 . The system of claim 5 wherein the plurality of physical inputs received from the user are finger-taps on said touch screen display.
7 . The system of claim 1 wherein the input device is at least one of a touch screen display, mouse pad, or keyboard.
8 . The system of claim 7 wherein the plurality of physical inputs received from the user are finger-taps on at least one of said touch screen display, mouse pad, or keyboard.
9 . The system of claim 1 wherein the time period is fixed.
10 . The system of claim 9 wherein the fixed time period is system-defined.
11 . The system of claim 9 wherein the fixed time period is user-defined.
12 . The system of claim 1 wherein the time period is variable and is dynamically determined by the system when the user starts and stops the physical input.
13 . The system of claim 1 wherein the processor determines the value of the physiological parameter by averaging all of interval data generated by said physical inputs.
14 . The system of claim 13 wherein the average interval data is derived by calculating a straight arithmetic average of the measured intervals.
15 . The system of claim 13 wherein the average interval data is derived by rejecting the longest and shortest interval data generated by the physical inputs and then averaging the remaining data.
16 . The system of claim 13 wherein the average interval data is derived by calculating a median value of the physical inputs.
17 . The system of claim 13 wherein the average interval data is derived by analyzing clusters of intervals and using a clustering algorithm to reject long or short intervals that should not be included.
18 . The system of claim 13 wherein the average interval data is displayed in real time and continuously updated with each physical input.
19 . A system for determining a physiological parameter of a patient, the system comprising:
an input device for receiving a plurality of physical inputs from a user, wherein said physical inputs comprise finger taps, and communicating to a memory data indicative of the frequency at which said plurality of physical inputs are received from the user within a time period, wherein said data comprises interval data; and
a processor in data communication with said memory wherein said processor determines at least one of the patient's respiration rate or pulse rate based upon said data.
20 . The system of claim 18 wherein the processor determines the value of the physiological parameter by averaging all of interval data generated by said physical inputs.
