But the simplicity of the operation is one of its chief advantages, for the patient sits upon the appliance in ease and comfort while receiving the cleansing stream, and by following the directions the time occupied in the operation need not exceed fifteen minutes, or about one-fourth of the time required by other methods--an unmistakably valuable saving of time and strain to busy or weakly people. The faucet is considered by experts as a most valuable feature, on account of the “dome” portion, which accurately fits the natural arch formed by the limbs when the body is in the seated position.
Many people are accustomed to use the bulb and fountain syringes in a reclining position and some physicians recommend the patient to kneel in the bath tub, with the body bent well forward: an irksome, disagreeable position and quite unnecessary. The theory is, that the water will flow into the body by gravitation, but they overlook the fact that the ascending and descending portions of the colon, being parallel in the body, the water, while flowing readily into the descending portions, would have to flow uphill in the ascending portions and by the time it reached there, the force would be exhausted. The weight of the body furnishes greater force, which is proportioned to the size and bulk of the patient, but is not perceptible to him, on account of the solid construction of the tip of the “injection point,” while the steady, uniform pressure exerted serves to distend the walls of the colon and thus liberate adherent matter. By far the great majority of people, however, use these crude appliances while seated over a vessel, which is decidedly injurious. By reference to the diagram of the digestive organs it will be seen that the “descending colon,” that portion which terminates in the rectum, is larger than either of the other divisions of that organ. In fact, its capacity (in the average adult) is about three pints, equivalent to three pounds. Now this weight, in a flexible organ like the colon, must cause a sagging down, exerting a serious strain upon its attachments to the abdominal wall, and by its pressure upon the sphincters will induce prolapse of the rectum. That is one reason why so many people find it almost impossible to receive enough water to make the treatment successful. When a physician, or trained nurse, is administering a high enema, it is a common practice to hold a folded towel against the rectum, to guard against this pressure and its possible results. The “dome” portion of the faucet (previously referred to) affords the desired support, automatically and effectually prevents any prolapse; while the handle of the faucet, projecting forward, between the limbs, may be manipulated with the greatest ease in controlling the flow of water; and, being seated on a warm cushion, the patient experiences a pleasant, soothing sensation, which completely allays any nervousness.
