Abstract
Abstract Apparatus for accomplishing irrigation of the colon and/or other intestinal portions through a stoma including an established path of fluid flow of irrigating liquid from a supply container through a feeding tube into a stoma cone or like structure and further including a peristaltic action monitoring device disposed within the path of fluid flow of irrigating fluid which is structured to indicate, through visual observation, the establishment of peristaltic action in the intestine which tends to reverse the direction of flow of the irrigating fluid and provides proper indication when the flow of the irrigating fluid to the intestine or colon should be stopped.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
227 words
An apparatus for controlled intestinal irrigation comprising: (a) a container means for supply and storage of irrigating liquid, (b) introduction means positionable adjacent to and in fluid delivering relation with an entrance to an intestine being irrigated for introducing liquid thereto, (c) conduit means disposed in interconnecting and fluid communicating relation between said container means and said introduction means, (d) flow regulating means connected to said conduit means and structured and disposed to stop and control liquid flow from said container means to said introduction means, whereby flow of irrigating fluid to the intestine is selectively stopped by said flow regulating means upon an indication of peristaltic action of the intestine by a flow indicator, (e) a flow indicator means connected to said conduit means between said container means and said introduction means and structured to accommodate liquid flow therethrough from said container means to the intestine and reversely from the intestine into said flow indicator means, (f) said flow indicator means first structured for visual observation of at least a portion of the interior thereof and including an indicator element movably disposed therein and within liquid flow passing therethrough, (g) said indicator element cooperatively structured and disposed relative to said flow indicator means for responsive displacement therein based on peristaltic action of the intestine during flow of liquid through said flow indicator means to the intestine.
Claim 2
Independent Claim
227 words
An apparatus for controlled intestinal irrigation comprising: (a) a container means for supply and storage of irrigating liquid, (b) introduction means positionable adjacent to and in fluid delivering relation with an entrance to an intestine being irrigated for introducing liquid thereto, (c) conduit means disposed in interconnecting and fluid communicating relation between said container means and said introduction means, (d) flow regulating means connected to said conduit means and structured and disposed to stop and control liquid flow from said container means to said introduction means, whereby flow of irrigating fluid to the intestine is selectively stopped by said flow regulating means upon an indication of peristaltic action of the intestine by a flow indicator, (e) a flow indicator means connected to said conduit means between said container means and said introduction means and structured to accommodate liquid flow therethrough from said container means to the intestine and reversely from the intestine into said flow indicator means, (f) said flow indicator means first structured for visual observation of at least a portion of the interior thereof and including an indicator element movably disposed therein and within liquid flow passing therethrough, (g) said indicator element cooperatively structured and disposed relative to said flow indicator means for responsive displacement therein based on peristaltic action of the intestine during flow of liquid through said flow indicator means to the intestine.
Claim 3
Dependent Claim
113 words
An apparatus as in claim 1 wherein said flow indicator means comprises a tube having a transparent wall portion and connected at opposite ends thereof to the conduit means for direction of liquid through said tube, said indicator element visible through said transparent wall portion and movable between opposite ends of said tube without preventing liquid flow through said tube in either direction, and said indicator element being movable toward one opposite end of said tube in response to liquid flow therethrough from said container means and movable towards the other of said opposite ends of said tube against the liquid flow from said container in response to peristaltic activity of the intestine.
Claim 4
Dependent Claim
24 words
An apparatus as in claim 2 comprising a level gauge secured to said tube for indication when said tube is in a horizontal orientation.
Claim 5
Dependent Claim
30 words
An apparatus as in claim 1 wherein said indicator element is a ball and said tube has a cylindrical interior of greater cross-sectional diameter than the diameter of said ball.
Claim 6
Dependent Claim
18 words
An apparatus as in claim 4 wherein said ball has a specific gravity greater than that of water.
Claim 7
Dependent Claim
53 words
An apparatus as in claim 1 further including holding means to hold said tube and securing means to attach said holding means to a fixed support, said holding means and securing means being relatively rotatable, and said holding means rotatable relative to said fixed support until said tube is in a horizontal position.
