HORACE R. ALLEN, OF INDIANAPOLIS, INDIANA.

SPECFICATIONforming part of Letters Patent No. 330,084, dated November 10, 1885.

Application filed August 10, 1885. Serial No. 173,898. (No model.) i

To all whom it may concern:

Beit known that l, HORACE R. ALLEN, a citizen of the United States, residing at Indianapolis,in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Syringes, 85o.; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to means for injecting fluids into the body.

The object is to inject iiuids, particularly liquids, into openings in the body-such as deep ulcers, iistulas, sinuses, but especially the rectum-without insertion of any instrument, such as the nozzle of a syringe, whereby all unpleasant sensation, irritation, and pain consequent upon such insertion are avoided, and in case of injection into the rectum, where the external parts are sensitiveas from iux, hemorrhoids, ulceration, iissure, or other cause--the tenesmus and severe pain so often following the introduction of a syringenozzle are obviated.

The invention consists, generally, in a syringe, a syringe attachment, or douche having an oriiice or conduit adapted to fit the outer portion of an opening, particularly the lower part of the rectum or the anus. The invention consists, particularly, in various embodiments hereinafter more fully described.

In the accompanying drawings, forming part of this specification, like letters and marks of reference indicate corresponding parts.

Figure 1 is an elevation showing perhaps the most primitive form of embodiment of the invention. Fig. 2 is an elevation showing a flexible pipe having a flaring eduction end, which may be either integral with the pipe or separate from and` capable of attachment thereto. Fig. 3 is a longitudinal sectional view of a syringe having the eduction end conformed to t upon or against an opening. Fig. 4 is a vertical sectional view of an attachment embodying the invention, and showing its application to a syringe reversibly, whereby either the small end or the expanded or iiaring end may be brought into use, as the circumstances of the case may demand. Fig. 5

is a longitudinal sectional view showing the invention as embodied in a convenient and readily-operative instrument or form of use. Fig. 6 is a similar view showing the attachment proper reversible, as in Fig. 4, but permanently connected to the tube. Fig. 6n is an elevation showing the outer end of the shank'in Fig. 6, where the reversible attachment is applied. Fig. 7 is a perspective view of an .instrument embodying the invention and applied to a suitable syringe.

, In purging a cavity or canal it is frequently desirable to effect the purpose without insertion therein of any part of the instrument employed. This may be the case as well where an injection is to be made as with water or any medicated or antiseptic substance in liquid or gaseous form,as where a cavity with collapsible wallssuch as a sinus in the soft parts-is to be depleted. It is especially desirable, however, when injections are to be made per (mum, and the parts are in an irritated or sensitive condition. means are here devised which can be operatively employed externally, or nearly so, and

- several forms of a device and of its embodiment to effect the purpose are illustrated, although it is obvious that the mere form of any one of them may be changed without deviating from the invention.

Referring to the drawings, A indicates the part or attachment to be applied. This part may be of hard or soft rubber or any other suitable material, and, as shown in Fig. 1, may be either the normal or widened opening a atthe end A of a pipe, B1, of sufficient firmness to rgtain rits shwapemfhen pressed intoA an operative position, as against the anus; or, as shown in Fig. 2, a tubular piece or head, A, of suitable size, separable from or integral with the pipe, and having a cup-shaped or flaring mouth or orifice, a,- or, as shown in Fig. 3, an appropriately-shaped mouth in a syringe. The orifice or head should be of the proper diameter to iit operatively just at the opening.

When in any of the forms of embodiment of the invention the widened or iiaring orifice is applied to the anus and pressed against the edges of the same, and has connection with a douche, faucet, or syringe from which liquid passes under a sufficient static pressure,

To this endor is forced, the liquid will readily pass up into the rectum without escaping laterally, gently nding its way through the natural channel without undueand forcible distention of the same, and at the same time supplying a gentle bath to the external parts and to the region of the sphincter muscle.

Sometimes it is desirable to apply the orice against the verge of the rectum, just outside of the sphincter muscle. In such case-it is well to have the end of the head somewhat conical, and the form of device shown in Fig. 4, in which the attachment A is shown as removable and reversible, and with a conical end, a', as well as a flaring end, a, may be employed. Here the attachment is shown as applied upon the nozzle B of an ordinary syringe by passing either end of the tube of the head over the same. soft rubber, a2, to form an elastic socket and tight joint, though this is not necessary where the attachment itself is of soft rubber.

The more convenient form of the invention is one lin which it is embodied as shown in Figs. 5 and 6, and where the part A is ap plied upon a suitably bent or a straight shank, B, which may be hollow and serve as a conduit for the liquid, and be provided with a handle, C. As shown here, the shank eX- tends through the handle and beyond it,form

ing an end, b, to be inserted into the educ-4 tion-pipe of a syringe. Instead of the projecting end,the handle itself may be constructed to t over an eduction-tubc.

To make the part A soft where it is to be applied, and the better to prevent lateral escape of liquid, it is Well to provide it with a covering of rubber or other suitable material, as shown at a3.

The hollow shank B may be employed .as a handle'to sustain a cone or other shaped'pad or bulb, with or without a discharge-tube, which pad will then be a head, A, the end of the handle entering the pad or bulb below where it is suitably shaped or enlarged to receive it.

Where it is desirable to have a conical as well as a flaring mouth, the form of attachment shown in Fig. 6 may be employed. Here The tube may be lined with the attachment is placed upon theend of the pipe B, which kis'closed at the end, supplied laterally with a hole, as shown'in Fig. 6, and provided with a collar, b', against which the attachment rests, being held in place` by a suitable nut, collar, or other device on the end of the pipe B. The tube through the attachment A is over that portion of the pipe in which is the hole, so that when it is desired to use either the end a or the end a it is only necessary to turn the head A on the pipe B until the respective part of the tube registers 4with the hole, when the liquid or other substance employed will iiow from that end. In this case the head Ais reversible to use either the flaring or the conical end without having to be detached. The head A thus forms a stop-cock, whereby either end of its tube may be used by simply turning it to register with the hole in the pipe B, the liquid being prevented from escaping from the other end. When the attachment A is turned into a position where no part of either end of its tube will be opposite the hole, there will be no escape of liquid at all.

Having thus fully described my invention,

Awhat I claim, and desire to secure by Letters Patent, is-

1. A syringe, syringe attachment, or douche having an orifice or a conduit adapted to fit the outer portion of an opening-such as the lower end of the rectum, or the anus-substantially as described, and for the purpose specified.

2. In combination with a suitable pipe, conduit, shank, or nozzle, a head provided with one or more discharge-orifices adapted to fit the lower or outer portion of the anus, substantially as and for the purpose described.

3. In combination'with a head, A, a tube or shank, B, and a handle, C, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witncsses.

HORACE R. ALLEN.
