This invention relates to a device for giving enemata, and for its general object aims to provide an appliance operative to preclude premature expulsion of the introduced fluid and thereby enable an attendant to positively control rectal injections.

Clarity in an understanding of this and other more particular objects and advantages in view will perhaps be advanced by here stating that enemata, as heretofore given, have required constant attention on the part of a nurse or other attendant. As a result thereof and particularly where the demands upon an attendant's time are relatively heavy-this condition being especially pronounced at the present time when hospitals are forced to operate with far less than the usual number of help-there is a not unnatural tendency to give enemata with undue haste. Aside from the pain to the patient caused by resulting bowel spasms, some patients, and this is especially evidenced in cases of a weak sphincter muscle of the anus, are entirely unable to retain the injected fluid, in consequence expelling the same prematurely. Bed linen unnecessarily soiled in this manner is one item which reflects itself in the exceptionally heavy laundering requirements of hospitals. Moreover, it becomes self-evident that an expulsion of enema fluid before the same has served its intended end of entirely loosening and softening congested feces within the bowel requires repetitive clyster operations which, if resorted to at too frequent intervals, can be quite harmful to the patient.

Having the foregoing in mind, the present invention aims to devise an enema control appliance providing a clyster tip in association with means functioning to fixedly hold the same within the rectum-in consequence obviating need for an attendant's presence during the enema-and additionally serving the office of a seal, preclud- 4 ing premature escape of the injected fluid. The device is, therefore, one which enables an attendant to insert the appliance, set the same for any desired degree of slow-feed flow, and then go about his or her other duties, giving other 4 enemata if called for, during the relatively protracted time period required to best consummate a softening of the stool. It will be thus apparent that the appliance operates to largely overcome spasms of the bowel and permit fluid, slowly injected, to reach the upper limits of the colon.

During the course of the enema, the ordinary convalescent patient can, of course, make slight adjustments in the fluid flow and can take the enema in comparative comfort with the bowel rel- 56 atively relaxed as distinguished from the usual rigidity which sympathetically follows when, as heretofore, it becomes necessary to exert a certain amount of effort in maintaining a contracted condition of the external sphincter muscle of the anus.

The present invention provides a highly satisfactory method of giving nutrient enemata, also retention enemata which are indicated in some 1( instances and are performed by clamping the fluid-supply tube at a point distal from the appliance or, otherwise stated, at a point intermediate the appliance and the container for the fluid.

In the field of retention enemata are, of course, '5 barium injections which are resorted to for X-ray purposes and which, previous to the present invention, have occasioned considerable annoyance to the medical fraternity due to premature expulsion of the liquid-suspended barium.

The invention serves the further and important end of providing an assured method of giving enemata to patients with a colostomy, namely, an artificial anus; the procedure consists in the new method of fixedly holding an enema tube 2' or, more properly, the rectal part thereof, within the rectum while coincidently sealing the anal canal against leakage, and in the novel construction, adaptation and combination of parts hereinafter described and claimed.

In the accompanying drawing: Figure 1 is a perspective view portraying the invention and showing the same applied to a patient preparatory to giving an enema.

Fig. 2 is a detail longitudinal vertical section of one embodiment with the view taken to an enlarged scale and being fragmentary to the extent that enema-flow tubes leading to and from the appliance proper and an air-delivery catheter are broken away. In this view the balloon elero ment which performs the holding and sealing office of the invention is shown in its inactive normal condition by full lines and in its active inflated condition by dotted lines.

Fig. 3 is a transverse vertical section taken to 5 an enlarged scale on line 3-3 of Fig. 2; and Fig. 4 is a view similar to Fig. 2, excepting that I have shown a somewhat modified construction in which the air duct which supplies pressure air for inflating the balloon is molded 0 into the enema-flow pipe as an integral part thereof.

First describing the invention as illustrated in Fig. 4 and which constitutes the now preferred embodiment, there is provided a rectal pipe de5 noted by the numeral 5 which is, or may be 2,457,244 3 molded from, rubber or one of the various applicable plastics to provide a main canal 6 open at the two ends and, along one side, present a longitudinal air duct 7. This duct connects toward the rear end of the pipe with a laterally projecting nipple 8 and extends forwardly to a point somewhat short of the forward limit of the pipe whereat the same terminates in a surface outlet 9. Thepipe As: tterminally be6ded 'or idtherwise suitablyr formed as, for example, by the instru- 10 mentality of embedding male hose fittings in the two ends to accommodate the attachment, to the rear end thereof, of a supply hose 40 -fromva fluid container (not shown) and, to the forward-end, of a clyster tip ! I forming the enema nozzle and having the usual vent or vents I ': 12 dn: tes an adapter embedded in thet-exposed; nipple 8, and attached thereto is a flexible catheter 13 to which is connected an air syringe 14 havin-g he usual one-way valve permitting atmospheric air 20 .to;:,bet drawn,:lirito:;the';bulb, while-, trappirigi..the -same against escape.

The enema may be now given by attaching the supply hose 10 to the rectal pipe and suspending the enema can or bottle at a relatively low elevation of, say, 12 to 16 inches, assuring a slow injection of the fluid and thereby permitting the latter to work gradually through the entire colon and effectively loosen and soften the feces without.devieloping bowel spasms.

:The appliance may be readily withdrawn for defecation by the instrumentality of removing -the syringe from the catheter to allow escape of ithe,.pressure-air- from the balloon. A valve for '-this purpose might of course be applied to obviate the need for removing the syringe. Syringes are-now produced to meet manifold require-ments. and there is available, and commonly used, a bulb including a non-return check-accompishing-the pumping function of the syringeand also equipped with a release valre to exIihdult the -pumped air when it isidesired ito re-lieve;the -pressure.
