Abstract
Abstract Colon washing apparatus and methods wherein water flow to the colon may be by gravity flow or by pumped flow, wherein temperature control of the wash water is controlled by mixing of hot and cold water or by means of a water heater means, wherein wash water pressure is controlled by water head or by pump output pressure, and by pressure flow valve controls, wherein pulsating water flow may be used, wherein oxygen may be introduced into the wash water, wherein water penetration into the colon may be assisted by abdominal massage, wherein the nozzle may be introduced through the colon by water jet action, and wherein angular water jets from the nozzle may cause washing action ahead of the nozzle. The apparatus is fail-safe in that alternative modes of operation are available in case of power failure. The patient can control the apparatus in case of operator absence or patient discomfort.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
207 words
Apparatus for use in washing the colon of a person, comprising an elevated tank having a bottom outlet, means for filling said tank with water, said tank having an overflow drain at an upper level, a cross conduit having at one end a flow connection to an implement for delivering water into a person's colon, a solenoid operated shut-off valve and a check valve in series in said cross conduit, a manifold connected to said bottom outlet of said tank and having valve controlled first, second and third branches, said first branch being connected to said cross conduit between said check valve and said solenoid valve to permit flow of water from said tank to said cross conduit in by-pass relation to said solenoid operated valve, said second banch being connected to said cross conduit upstream of said check valve and said solenoid operated valve, and said third branch being connected to the inlet of a pump, the outlet of which is connected to said cross conduit at a point upstream of said check valve and said solenoid operated valve whereby water may be transmitted from said tank to said implement by gravity through said first and second branches or by said pump through said third branch.
Claim 2
Dependent Claim
207 words
Apparatus for use in washing the colon of a person, comprising an elevated tank having a bottom outlet, means for filling said tank with water, said tank having an overflow drain at an upper level, a cross conduit having at one end a flow connection to an implement for delivering water into a person's colon, a solenoid operated shut-off valve and a check valve in series in said cross conduit, a manifold connected to said bottom outlet of said tank and having valve controlled first, second and third branches, said first branch being connected to said cross conduit between said check valve and said solenoid valve to permit flow of water from said tank to said cross conduit in by-pass relation to said solenoid operated valve, said second banch being connected to said cross conduit upstream of said check valve and said solenoid operated valve, and said third branch being connected to the inlet of a pump, the outlet of which is connected to said cross conduit at a point upstream of said check valve and said solenoid operated valve whereby water may be transmitted from said tank to said implement by gravity through said first and second branches or by said pump through said third branch.
Claim 3
Dependent Claim
17 words
The combination of claim 1, said means for filling said tank with water including water heater means.
Claim 4
Dependent Claim
48 words
The combination of claim 2, said water heater means comprising an elongate tank having an electric heating coil therein through which said water flows toward said tank, said water heater means also comprising a temperature controller for controlling operation of said heating coil in response to water temperature.
Claim 5
Dependent Claim
72 words
The combination of claim 3, said means for filling said tank with water comprising valved conduits from hot and cold water sources which are joined before entry into said water heater means, whereby water passed through said water heater means for delivery into said tank may be temperature controlled by controlling the proportion of hot and cold water from said sources and alternatively by operation of said heating coil and said controller.
Claim 6
Dependent Claim
30 words
The combination of claim 1, said tank having dual temperature indicating means whereby correct temperature of water therein is indicated in the event of failure of one temperature indicating means.
Claim 7
Dependent Claim
31 words
The combination of claim 5, wherein said means for filling said tank with water includes float valve means for controlling water flow into said tank and water level in said tank.
Claim 8
Dependent Claim
31 words
The combination of claim 1, wherein said means for filling said tank with water includes float valve means for controlling water flow into said tank and water level in said tank.
Claim 9
Dependent Claim
11 words
The combination of claim 1, said implement comprising a rectal nozzle.
Claim 10
Dependent Claim
17 words
The combination of claim 1, said implement comprising a nozzle having plural forwardly slanted angular water outlets.
Claim 11
Dependent Claim
40 words
The combination of claim 1, said implement comprising a nozzle having plural rearwardly slanted angular water outlets, whereby water discharge propels said nozzle further into the colon and tends to wash loosened feces toward the rectal outlet from the colon.
