Abstract

A vesicovaginal apparatus for ambulatory monitoring of the detrusor pressure exerted by a bladder includes a first transducer configured and dimensioned for insertion into and retention by the bladder of a wearer during ambulatory motion for sensing the total pressure within the bladder, and a second transducer configured and dimensioned for insertion into and retention by the vagina of a wearer during ambulatory motion for sensing the pressure within the vagina. A portable recorder in operative communication with the first and second transducers records the total pressure sensed in the bladder and the pressure sensed in the vagina, with the difference indicating the detrusor pressure exerted by the bladder of the wearer.

Claims

1. A vesicovaginal apparatus for ambulatory monitoring of the detrusor pressure exerted by a bladder comprising:

(A) first transducer means configured and dimensioned for insertion into and retention by the bladder of a wearer during ambulatory motion for sensing the total pressure within the bladder;

(B) second transducer means configured and dimensioned for insertion into and retention by the vagina of a wearer during ambulatory motion for sensing the pressure within the vagina, said second transducer means comprising an inflatable and deflatable pessary and a transducer for sensing pressure mounted thereon, said pessary when inflated precluding unintended separation of said transducer therefrom but when deflated enabling easy separation of said transducer therefrom; and

(C) portable means in operative communication with said first and second transducer means for recording the total pressure sensed in the bladder and the pressure sensed in the vagina, with the difference indicating the detrusor pressure exerted by the bladder of the wearer.

2. The apparatus of claim 1 wherein said second transducer means is configured and dimensioned for insertion into and retention by the upper two-thirds of the vagina.

3. The apparatus of claim 1 wherein each of said first and second transducer means includes a microtip transducer for sensing pressure.

4. The apparatus of claim 3 wherein said transducers of said first and second transducer means are disposed in the bladder and the vagina, respectively.

5. The apparatus of claim 3 wherein said portable disposed externally of the body of the wearer.

6. A vesicovaginal apparatus for ambulatory monitoring of the detrusor pressure exerted by a bladder comprising:

(A) first transducer means configured and dimensioned for insertion into and retention by the bladder of a wearer during ambulatory motion for sensing the total pressure within the bladder;

(B) second transducer means configured and dimensioned for insertion into and retention by the upper two-thirds of the vagina of a wearer during ambulatory motion for sensing the pressure within the vagina, said second transducer means comprising an inflatable pessary and a transducer for sensing pressure, releasably mounted thereon said inflatable pessary when inflated precluding unintended separation of said transducer therefrom but when deflated enabling easy separation of said transducer therefrom; and

(C) portable means disposed externally of the body of the wearer and in operative communication with said first and second transducer means for recording the total pressure sensed in the bladder and the pressure sensed in the vagina, with the difference indicating the detrusor pressure exerted by the bladder of the wearer.
