Abstract

A method is provided for assessing urinary function including removably coupling a first test module to a portable control device, selecting from a plurality of different tests a first test to assess urinary function, the selection being made based on first module identification information obtained by the control device from the test module, and performing the first test. The method may also include one or more of the steps of inserting an insert member coupled to the first test module at least partially into a patient'"'"'s urinary tract, infusing fluid through the insert member into the urinary tract, and measuring pressure within the urinary tract as fluid is infused therein. The method may further include uncoupling the first test module from the portable control device, coupling a second test module to the portable control device, selecting a second test to assess urinary function based on second module identification information obtained by the control device from the second test module, and performing the second test.

Claims

1. A method for assessing urinary function comprising:

removably coupling a first test module to a portable control device;

selecting from a plurality of different tests a first test to assess urinary function, the selection being made based on first module identification information obtained by the control device from the test module;

performing the first test by inserting an insert member coupled to the first test module into a patient'"'"'s urinary tract distal of the urethral sphincter, infusing fluid through the insert member and into the urethral canal distal of the urethral sphincter, and determining pressure within the urethral canal distal of the urethral sphincter as fluid is infused therein.

2. The method according to claim 1, wherein the determining pressure step comprises determining the Urethral Resistance Pressure.

3. The method according to claim 2, wherein the control device includes a processor, the method further comprising the step of providing electronic information corresponding to the determined pressure to the processor.

4. The method according to claim 3, wherein the control device further includes a display device, the method further comprising the step of displaying on the display device information corresponding to the determined Urethral Resistance Pressure.

5. A method for assessing urinary function comprising:

removably coupling a first test module to a portable control device, wherein the control device includes a processor and a display device;

selecting from a plurality of different tests a first test to assess urinary function, the selection being made based on first module identification information obtained by the control device from the test module;

inserting an insert member coupled to the first test module into a patient'"'"'s urinary tract with at least a portion of the insert member extending into the bladder;

infusing fluid through the insert member and into the bladder, and determining pressure within the bladder as fluid is infused therein;

providing electronic information corresponding to the determined pressure to the processor; and

displaying on the display device information corresponding to the determined pressure.

6. A method for assessing urinary function comprising:

removably coupling a first test module to a control device, wherein the test module includes a tubing assembly defining a first fluid conduit between a first fluid inlet and a first fluid outlet, and wherein the insert member is coupled to the first fluid outlet so that fluid infused through the first fluid conduit passes through the insert member, and wherein the control device includes a processor and memory storing therein a plurality of software routines corresponding to a plurality of different tests to assess urinary function, whereby said coupling enables the processor to identify the test module attached thereto, and based on said identification to select one of said plurality of software routines;

inserting an insert member coupled to the first test module at least partially into a patient'"'"'s urinary tract, wherein the insert member is a meatus plug dimensioned for insertion into the urethral canal distal of the urethral sphincter;

infusing fluid into the patient'"'"'s urinary tract through the insert member; and

the first test module in combination with the control device measuring pressure within the urinary tract as fluid is infused therein.

7. A method for assessing urinary incontinence comprising:

removably coupling a first test module to a control device having a processor and memory for storing therein a plurality of software routines corresponding to a plurality of different tests to assess urinary function, whereby said coupling enables the processor to identify the test module attached thereto, and based on said identification to select one of the plurality of software routines;

inserting an insert member coupled to the first test module at least partially into a patient'"'"'s urinary tract;

infusing fluid into the patient'"'"'s urinary tract through the insert member;

the first module in combination with the control device measuring pressure within the urinary tract as fluid is infused therein;

uncoupling the first test module from the control device;

coupling a second test module to the control device, whereby said coupling enables the processor to identify the second test module attached thereto, and based on said identification to select a different one of said plurality of software routines;

inserting a second insert member coupled to the second test module at least partially into a patient'"'"'s urinary tract;

infusing fluid into the patient'"'"'s urinary tract through the second insert member; and

the second test module in combination with the control device measuring pressure within the urinary tract as fluid is infused therein.

8. A method for assessing a medical condition comprising:

removably coupling a first test module to a control device to form a portable medical system, wherein the control device includes a processor and a module detection device electrically coupled to the processor and wherein the first test module includes a module identification device and a tubing assembly including a first fluid conduit between a first fluid inlet and a first fluid outlet;

the processor selecting from a plurality of tests, a first medical assessment test for assessing urinary incontinence based on first module identification information obtained by the module detection device from the module identification device;

inserting an insert member having a channel therethrough and coupled to the first fluid outlet of the first test module at least partially into a predetermined location in a patient'"'"'s urethra;

infusing fluid through the first fluid conduit and insert member channel and into a patient'"'"'s urethral canal;

obtaining pressure information within the urethral canal as fluid is infused therein; and

utilizing the obtained pressure information in performing the first medical assessment test.

9. The method according to claim 8, wherein the insertion step comprises inserting at least a portion of the insert member into the urethral canal distal of the urethral sphincter.

10. The method according to claim 9, wherein the pressure information is the Urethral Resistance Pressure.

11. The method according to claim 8, wherein the control device includes a processor, the method further comprising the step of providing electronic information corresponding to the determined pressure to the processor.

12. The method according to claim 11, wherein the control device further includes a display device, the method further comprising the step of displaying on the display device information corresponding to the determined pressure.

13. A method for assessing urinary function comprising:

providing a control device having a processor and memory storing therein a plurality of software routines corresponding to a plurality of different tests to assess urinary function;

providing at least one test module including an insert member;

removably coupling the test module to the control device, whereby said coupling causes the processor to automatically identify the test module attached thereto, and based on the identification to automatically select one of the plurality of software routines;

inserting the insert member at least partially into a patient'"'"'s urinary tract;

executing the selected software routine, wherein said execution automatically controls, in a predetermined manner, infusion of fluid into the patient'"'"'s urinary tract through the insert member; and
