Application May 8, 1951, Serial No. 225,150

This invention relates to nozzles and particularly to devices of this character which are used with enemas or colonic irrigation. Heretofore it has been customary to use a nozzle not provided with bulbous, egg shaped or oval enlarged portion at the outer extremity of the nozzle. Such nozzles are also generally provided with a rounded enlargement or head to act as a closure when the nozzle i inserted.

One object of the invention is to provide a nozzle having at its lower end a small rounded point which is easily inserted for use, said nozzle having a hole l2 passing longitudinally through its center for the flow of water or other liquid therethrough.

Another object of the invention is to provide a nozzle having a hose connection at its upper end and adjacent thereto a suitable flange for limiting the application of the nozzle into operative position.

A further object is to provide intermediate the ends of the nozzle a suitable enlargement tapered in the direction of the lower extremity and extending thereto whereby the portion of the enlargement nearest the upper end is formed with a shoulder adapted to oppose any casual withdrawing movement of the nozzle when in position of use, and the long gradually tapered surface facilitates the easy application of the device into operative position.

With these general objects in view, the invention will now be described by reference to the accompanying drawings illustrating one form of construction which I have devised for embodying the proposed improvements after which those features deemed to be novel will be particularly set forth and claimed. In the drawing Fig. 1 is a plan view of the nozzle with the hose attached.

Fig. 2 is a longitudinal section through the center of the nozzle.

Fig. 3 is a transverse section taken on the line 3-3 of Fig. 1.

This device is only illustrated and described as applied to enemas or colonic irrigation but it is to be emphasized at the outset that the essential features thereof are intended to be incorporated in internal applicators for other equivalent uses such as rectal dilators. It is to be understood, therefore, that I do not confine my improvements specifically to enemas as in the main my invention is intended to also comprehend other forms of internal applicators.

Referring now to the drawings in detail the numeral 2 designates the body of the nozzle as 2 Claims. (01. 128-242) a whole being provided at its upper end with an integral nipple 3 for attaching thereto a tube 4 leading to a syringe bulb or equivalent water container not shown.

Adjacent to and below the nipple 3 is an abutment collar 5, the peripheral surface 6 of said collar being preferably of downwardly tapering or inverted conical-like formation adapted to form a shoulder element or limiting stop to control the appropriate degree of maximum insertion of the nozzle.

The portion of the nozzle directly beneath the collar or limiting stop is a short cylindrical portion 1 which extends downwardly to an enlargement 8 suitably tapered downwardly to the lower end 9 of the nozzle thereby forming a long gradually tapered surface II] which facilitates the easy application of the device into operative position. That portion of the enlargement 8 which is nearest to the short cylindrical portion 1 is formed with a shoulder ll adapted to oppose any casual withdrawing movement of the nozzle when in position of use.

The nozzle may be made of a single piece of metal, rubber, plastic or the like and is therefore inexpensive to manufacture.

It will be observed that the lower end 9 of the nozzle terminates with a small rounded point which is easily inserted for use and the long gradually tapered surface l0 facilitates the easy application of the device into operative position.

When the nozzle is inserted in operative position the shoulder ll opposes any casual withdrawing movement of the nozzle.

It is obvious that a patient using an enema provided with the nozzle above described can relax and recline in a most comfortable position and be free from any physical or nervous tension due to the improved construction of the nozzle as above described.

Obviously the invention is not limited to the specific detail of construction disclosed herein but is capable of other modification and change without departing from the spirit and scope of the appended claims.

Having now particularly described my invention and the manner of its use, I claim:

1. A nozzle adapted to be used with an enema, having a hole extending longitudinally therethrough, a nipple integral with the upper end of the nozzle, an abutment collar adjacent to and beneath said nipple, a short cylindrical portion beneath said collar, an enlargement adjacent the lower end of the cylindrical portion which gradually tapers down to the lower end of the nozzle,

said lower end consisting of a rounded point, said rounded point and tapering enlargement adapted to facilitate easy insertion of the nozzle into operative position.

2. A nozzle adapted to be used with an enema, said nozzle being round in cross-section and having a hole extending longitudinally and centrally therethrough, a nipple integral with the upper end of the nozzle, an abutment collar adjacent to-and beneathsaid nipple, a short cylin drical portion beneath said collar, an enlargement adjacent the lower end of the cylindrical portion which gradually tapers down to the lower end of the nozzle, said lower end consisting of a JOHN B.
