Abstract: A support for the prone back during an upper enema, in which the legs are folded, with the feet resting on footrests and the buttocks adjacent to an effluent shield which stops the effluent and allows it to drop into a toilet, on which the lower part of the support rests. The support is collapsible for transport or storage, as is a stand which is beneath the center of gravity of body plus support. This stand makes contact with the support on both sides of the center of gravity. At discharge it and the toilet bowl span the center of gravity; during the enema the patient may, by manipulating a lever, raise the buttock part of the support by means of a linkage as desired in order to produce a more thorough irrigation of the colon. Provision is also made for increasing colonic reaction by color and by reflexology prods on the soles of the feet.
