Biofeedback training of anal and rectal muscles

摘要

A probe including a housing, a rectal muscle air bag, a rectal tube, an anal muscle air bag, and an anal tube is provided. The rectal muscle air bag mounts to the housing a first distance from a non-insertion end. A rectal tube is connected to the rectal muscle air bag at a first end and to a first pressure sensor at a second end. The anal muscle air bag is mounted to the housing a second distance from the non-insertion end. The anal tube is connected to the anal muscle air bag at a first end and to a second pressure sensor at a second end. The first distance is selected to position the rectal muscle air bag adjacent a rectal muscle, and the second distance is selected to position the anal muscle air bag adjacent an anal muscle when the housing is inserted in the rectum.

主权项

1. A probe comprising:
a housing configured for insertion into a rectum, the housing having an insertion end and a non-insertion end; a rectal muscle air bag, wherein the rectal muscle air bag is mounted to the housing a first distance from the non-insertion end, wherein the first distance is selected to position the rectal muscle air bag adjacent a rectal muscle when the housing is inserted in the rectum; a rectal tube connected to the rectal muscle air bag at a first end of the rectal tube to provide a first vent for the rectal muscle air bag, wherein the rectal tube is further configured for connection to a first pressure sensor at a second end of the rectal tube; an anal muscle air bag, wherein the anal muscle air bag is mounted to the housing a second distance from the non-insertion end, wherein the second distance is selected to position the anal muscle air bag adjacent an anal muscle when the housing is inserted in the rectum; an anal tube connected to the anal muscle air bag at a first end of the anal tube to provide a first vent for the anal muscle air bag, wherein the anal tube is further configured for connection to a second pressure sensor at a second end of the anal tube; a stool stimulation air bag mounted to the housing at the insertion end; a stool stimulation tube connected to the stool stimulation air bag at a first end of the stool stimulation tube to provide a first vent for the stool stimulation air bag, wherein the stool stimulation tube is further configured for connection to a fluid source at a second end of the stool stimulation tube; and a valve connected to the stool stimulation tube and configured to control a flow of fluid into the stool stimulation tube.
