Colon hydrotherapy and evacuator system
First Claim
1. An apparatus for providing a colonic lavage to a patient comprising:
- a container for receiving and holding a lavage liquid;
a speculum for insertion through the anal canal and into the colon of the patient, said speculum defining a longitudinal passage therethrough and having a nozzle opening for placement within the colon, a discharge opening for placement outside the anal canal, and a liquid inlet opening for placement outside the anal canal;
a liquid delivery conduit in communication at one of its ends with said container and in communication at its other end with said liquid inlet opening;
a pump means disposed within said container for delivering lavage liquid under pressure from said container through said liquid delivery conduit to said liquid inlet opening of said speculum;
a collection chamber for receiving contaminated lavage liquid;
a filter disposed on the top of said collection chamber for removing odor and bacteria from the air within said chamber as the chamber fills with contaminated lavage liquid;
a discharge conduit having a resilient collapsible portion, said discharge conduit being in communication at one of its ends with said discharge opening and in communication at its other end with said collection chamber;
means for selectively closing and opening said discharge conduit, said means comprising a pinch valve for selectively collapsing and releasing the resilient collapsible portion of the discharge conduit;
means for creating a pulsing action of lavage liquid through said inner opening of said speculum comprising means for alternately actuating said pump means while simultaneously closing said discharge conduit and deactuating said pump means while simultaneously opening said discharge conduit.

Abstract
An apparatus and method for providing a colonic lavage to a patient comprises a speculum for insertion into the colon of the patient with the speculum being generally tubular and having a tapered end within the colon with opposing openings formed therein and discharge and inlet openings outside the anal canal. The inlet opening is connected to a lavage liquid holding chamber through an inlet conduit and the discharge conduit is connected to a collection chamber through a discharge conduit. The discharge conduit has a resilient collapsible portion that passes through a pinch valve that can be actuated to close the discharge conduit. In operation, lavage liquid is pumped from the holding chamber while the pinch valve is closed causing the colon to fill with liquid. When the colon is full, pumping is discontinued and the pinch valve opened allowing liquid and loosened fecal matter within the colon to be purged through the discharge conduit to the collection chamber.

1. An apparatus for providing a colonic lavage to a patient comprising:
-
a container for receiving and holding a lavage liquid; a speculum for insertion through the anal canal and into the colon of the patient, said speculum defining a longitudinal passage therethrough and having a nozzle opening for placement within the colon, a discharge opening for placement outside the anal canal, and a liquid inlet opening for placement outside the anal canal; a liquid delivery conduit in communication at one of its ends with said container and in communication at its other end with said liquid inlet opening; a pump means disposed within said container for delivering lavage liquid under pressure from said container through said liquid delivery conduit to said liquid inlet opening of said speculum; a collection chamber for receiving contaminated lavage liquid; a filter disposed on the top of said collection chamber for removing odor and bacteria from the air within said chamber as the chamber fills with contaminated lavage liquid; a discharge conduit having a resilient collapsible portion, said discharge conduit being in communication at one of its ends with said discharge opening and in communication at its other end with said collection chamber; means for selectively closing and opening said discharge conduit, said means comprising a pinch valve for selectively collapsing and releasing the resilient collapsible portion of the discharge conduit; means for creating a pulsing action of lavage liquid through said inner opening of said speculum comprising means for alternately actuating said pump means while simultaneously closing said discharge conduit and deactuating said pump means while simultaneously opening said discharge conduit. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11)

12. A method for clearing a blockage from a speculum of the type having a tubular body defining a single longitudinal passageway therethrough, a tapered end with opposing nozzle openings in communication with said passageway for insertion into the colon of a patient and a discharge end having discharge and liquid inlet openings in communication with said passageway for positioning outside the anal canal comprising the steps of:
-
selecting a flow rate for moving liquid through the liquid inlet opening; moving liquid through the liquid inlet opening while preventing the flow of liquid through the discharge opening; discontinuing the movement of liquid through the liquid inlet opening while allowing the flow of liquid through the discharge opening; and repeating the steps of moving liquid through the liquid inlet opening and discontinuing the movement of liquid through the liquid inlet opening in a rapid, alternating manner to generate a pulsating flow of liquid through the nozzle openings to break up the blocking material so that it can flow through said longitudinal passageway and out the discharge opening.
