Abstract

A system for patient diagnostic testing includes the physiological data output is in a two dimensional graphical format. Optionally, the report includes imaging data. Color is a dimension provided to the graphical presentation of normal patient data in horizontal and vertical dimensions. Detrusor pressures are obtained. One detrusor pressure is the difference between average data points of the bladder and rectal pressures. The other is obtained by subtracting curve fitted rectal and bladder pressures. The displayed data is a presentation including bladder capacity information, pressure characteristics, and data as a function of volume such that bladder volume is indicated.

Claims

1. A method for obtaining diagnostic test data including data output of a specific patient comprising:

representing on a single report, at least a two dimensional graphical presentation of physiological data of a patient and at least a two dimensional graphic format of data of a normal individual relative to the specific patient;

processing raw data prior to representing the physiological data on the report by smoothing the raw data prior to the representation thereby to minimize noise and provide smoothed data, and subsequently processing the smoothed data to effect curve fitting;

displaying the physiological data as a representation of urodynamic data of the patient, such representation being a presentation including bladder volume, a pressure characteristic, and the physiological data being represented as a function of bladder volume; and

representing as an output, the urodynamic data and X-ray imaging data.

2. A method as claimed in claim 1 including the incorporation of zones as a dimension to the graphical presentation of the physiological data of the normal individual, such normal data being in horizontal and vertical dimensions.

3. A method as claimed in claim 2 wherein the zones are colors, the colors being selectively green, yellow and red.

4. A method as claimed in claim 2 including filtering the raw data, such that when operating under at least one of the conditions that, when a rate of rise of pressure exceeds a pre-set value the raw data obtained under such conditions is discarded, or when a pressure exceeds an average pressure that had been maintained over a recent time period by more than a pre-set amount, the raw data obtained under such conditions is discarded.

5. A method as claimed in claim 2 including obtaining a detrusor pressure, such detrusor pressure being obtained by first smoothing a bladder pressure data and a rectal pressure data obtained from a measurement of pressure in the abdomen and then subsequently performing a subtraction of such bladder pressure and rectal pressure to obtain the detrusor pressure.

6. A method as claimed in claim 5 wherein the graphical presentation contains two detrusor pressures, one detrusor pressure being the difference between a time spaced average data points of the bladder and rectal pressures and the other pressure being obtained by subtracting curve fitted rectal and bladder pressures.

7. A method as claimed in claim 1 including obtaining the raw data through analog measurement means, an analog to digital data conversion means for converting the raw data to a digital input, a software program for reading the digital input, means for sampling the converted raw data for minimizing artifacts in the converted raw data that are substantially non physiological while retaining the physiological data.

8. A method as claimed in claim 1 including providing the colors of green, yellow and red as background on which the physiological data is displayed, and the presentation includes bladder capacity information as vertical lines, and pressure as horizontal colored areas.

9. A method as claimed in claim 1 including analyzing in real time the collected raw data which has been processed, and analyzing the processed data in relation to data obtained after obtaining the collected raw data, and including taking the collected raw data from the patient and calculating characteristics for displaying the physiological data.

10. A method as claimed in claim 1 including directing a catheter into a bladder, including filling the bladder with fluid, and measuring the bladder pressure, and locating in the abdomen a sensor for measuring pressure in the abdomen in the area outside the bladder.

11. A method as claimed in claim 1 including rendering the representation of urodynamic data as an output display reported in relation to color, the color being selectively representative of physiological significant data.

12. A method as claimed in claim 1 wherein the diagnostic test data output of a specific patient is related relative to representative data of a normal individual.

13. A method for obtaining diagnostic test data including data output for a patient comprising:

representing on a single report, a graphical presentation of physiological data of the patient and imaging data of the patient;

processing raw data prior to representing the physiological data on the report by smoothing the raw data prior to the representation thereby to minimize noise and provide smoothed data, and subsequently processing the smoothed data to effect curve fitting;

displaying the physiological data as a representation of urodynamic data of the patient, such representation being a presentation including bladder volume, a pressure characteristic, and the physiological data being represented as a function of bladder volume; and

representing as an output, the urodynamic data and X-ray imaging data.

14. A method for obtaining urodynamics diagnostic test data of a patient comprising representing the production of a graphical presentation report of physiological data of a specific patient, and imaging data of internal anatomical features of the patient, including incorporating zones as a dimension to the graphical presentation of data of a normal individual relative to the physiological data of specific patient data, such normal data being portrayed in horizontal and vertical dimensions;

analyzing in real time the physiological data and further analyzing the collected data in relation to data obtained after obtaining the physiological data;

processing and presenting the, including taking the patient data and calculating the characteristics for the display; and

displaying the physiological data as a presentation, such presentation including bladder capacity information, and a pressure characteristic, and additionally displaying the imaging data.

15. A method as claimed in claim 14 wherein the zones are colors, the colors being selectively green, yellow and red.

16. A method as claimed in claim 15 including providing the colors of green, yellow and red as background on which the physiological data is displayed, and the presentation includes bladder capacity information as vertical lines, and pressure as horizontal lines.

17. A method as claimed in claim 14 wherein the diagnostic test data output of a specific patient is related relative to representative data of a normal individual.

18. A method for obtaining urodynamic diagnostic test data comprising representing data output of a patient as a graphical presentation report of the test data of the patient and including incorporating different discrete color zones as a background dimension to the graphical presentation of data of a relatively normal individual in horizontal and vertical dimensions, obtaining detrusor pressures, one detrusor pressure being the difference between data points of the bladder and rectal pressures and the other being obtained by subtracting rectal and bladder pressures, including displaying as the data, bladder capacity information, pressure characteristics, and data as a function of bladder volume;

and

relating data output of a specific patient relative to urodynamic data of a normal individual.
