Abstract: The single use catheter has a lumen with a hydrophobic filter tip at one end. The lumen is divided into two parallel conduits. A first conduit terminates in a one-way valve. A syringe is attached to the one-way valve. Air, saline solution or sterilized water can be introduced through the one-way valve and inflate a cuff about the lumen. The second parallel conduit terminates in a charcoal filter for elimination of bowel gas. The one-way valve prevents deflation of the cuff unless the lumen is cut to allow the fluid from the cuff to exit and deflate the cuff.

Abstract: A method and apparatus for alerting a colostomate or medical attendant to the presence of fecal matter. The device includes a hollow plug detachably securable to a flexible port positioned about the stoma. The port carries an alarm circuit which is triggered when fecal matter enters the plug lumen which will alert the colostomate to an impending episode. The signal may be vibratory, audible or visible and may be transmitted to a remote location. The device includes an inflatable air cuff which, when inflated, presents a physical barrier to the passage of fecal matter. Gas may pass through filters in the tube. The method involves positioning the device in the stoma, inflating the cuff and generating an alarm when matter is sensed.
