1. An apparatus for colonic lavage comprising:
- (a) a water mixing valve for receiving hot and cold water under pressure and mixing them to arrive at a desired temperature, said mixing valve having an outlet port;
(b) water pressure regulating valve means coupled to the outlet port of said water mixing valve for receiving water therefrom, said water pressure regulating valve means having an outlet and including first valve means for limiting the maximum pressure of the water at its outlet and second valve means for adjusting the water pressure to specific valves below that maximum limit;
(c) a water temperature gage coupled to the outlet of said water pressure regulating valve means to provide a visual indication of the water temperature;
(d) a water pressure gage coupled to the outlet of said water pressure regulating valve means to provide a visual indication of the water pressure at the outlet of said water pressure regulating valve means;
(e) a speculum for insertion into the anal canal of a patient for lavaging the patient'"'"'s colon and extracting matter lodged therein; and
(f) manifold means connected between the outlet of said water pressure regulating valve means and said speculum for delivering water to said speculum and for receiving the extracted matter therefrom, said manifold means having a discharge port through which the extracted matter passes.

Abstract
A unit including mechanisms and instrumentation for precision, temperature and pressure control of water which is directed through a speculum that continuously irrigates a patient'"'"'s colon and drains the water along with extracted matter through an illuminated viewing chamber provided in the unit. The unit also includes an oxygen pressure regulator and a special mixing manifold by which the oxygen or other medicinal fluids may be optionally introduced into the water, and a device by which a specimen of extracted matter may be optionally retained for subsequent laboratory analysis.

11. An apparatus for colonic lavage comprising:
-
(a) a cabinet having a front panel; (b) a water mixing valve for receiving hot and cold water under pressure and mixing them to arrive at a desired temperature, said mixing valve mounted in the front panel and having an outlet port; (c) water pressure regulating valve means coupled to the outlet port of said water mixing valve for receiving water therefrom, said water pressure regulating valve means having an outlet and including first valve means contained within said cabinet for limiting the maximum pressure of the water and a second valve means mounted in the front panel of said cabinet for adjusting the water pressure at various valves below that maximum limit; (d) a water temperature gage coupled to the outlet of said water pressure regulating valve means to provide a visual indication of the water temperature, said water temperature gage mounted in the front panel of said cabinet; (e) a water pressure gage coupled to the outlet of said water pressure regulating valve means to provide a visual indication of the water pressure at the outlet of said water pressure regulating valve means, said water pressure gage mounted in the front panel of said cabinet; (f) a speculum for insertion into the anal canal of a patient for lavaging that patient'"'"'s colon and extracting matter lodged therein; and (g) manifold means connected between the outlet of said water pressure regulating valve means and said speculum for delivering water to said speculum and for receiving the extracted matter therefrom, said manifold means having a discharge port through which the extracted matter passes. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
