CARLETON SAWYER, 0F FOXBORO, MASSACHUSETTS.

RECTAL IRRIGATOR.

Application filed November 25, 1908, Serial No. 464,368. Renewed February 27, 1913.

To all whom it may concern Be it known that I, CARLETON SAWYER, a citizen of the United States, residing at FoXboro, county of Norfolk, State of Massachusetts, have invented an Improvement in Rectal Irrigators, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

This invention has for its object the production of novel, simple and efficient apparatus whereby oil injections can be administered in a cleanly, safe and easily controlled manner Without the use of piston syringes, and whereby the objectionable features usually attendant upon rectal oil irrigations are wholly obviated.

The so-called fountain type of syringe is at the present time probably the most easily managed and readily controlled form of irrigating apparatus, but its use with oil is highly objectionable on account of the deteriorating action of the oil upon the rubber, and the very practical difliculty of cleansing after such use.

Piston syringes, whether of hard rubber, glass or metal are objectionable for various reasons, principally because of the difliculty experienced in properly controlling their action.

In my present invention I have devised an apparatus for rectal irrigation particularly adapted for use in connection with oil, or oleaginous liquids, which can be used in connection with a fountain syringe but without any possibility of the oil or other irrigating liquid coming in contact therewith, and in carrying out my invention I make use of the principle of the displacement of one liquid by another, thereby dispensing absolutely with pistons or similar devices.

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a view in side elevation of an irrigating apparatus embodying one form of my invention, in readiness for use; Fig. 2 is an enlarged sectional detail of the fitting for the reservoir or holder which contains the irrigating liquid, showing the outlet therefor and the inlet for the displacing liquid.

In my invention I take advantage of the relative specific gravities of oil and water, and so construct the apparatus that the oil Specification of Letters Patent.

is forced from a suitable reservoir or holder by an incoming body of water.

Referring to the drawings, the oil reservoir or holder is preferably an elongated glass bottle 1 of suitable dimensions to be conveniently handled and to hold the required quantity of irrigating liquid, the filling opening or mouth 2 of the holder when in use being closed by a tight fitting, tubular stopper 8 having a globular head 4. A long outlet tube or conduit 5 passes through the stopper head 4 and its inner end extends nearly to the bottom of the holder 1, see Fig. 1, the outer end of said tube projecting beyond the head 4, as at 6, and is preferably bent laterally, as at 7. The fitting comprising the stopper and its head, and the inlet and outlet ducts or tubes may be made of glass ormetal, as most convenient, the head 4 having a bent inlet tube or duct 8 leading thereinto, as shown.

In Fig. 2 the arrows show the direction of the incoming and outgoing liquids, and in practice the irrigating nozzle 9 is connected by a length of flexible tubing 10 with the end 7 of the outlet conduit, and a controlling valve 11 of common form may be applied to the tubing. The latter can be renewed from time to time as it is deteriorated by contact with the oil, and is of small cost. Any suitable source of water supply may be connected with the inlet conduit 8, and the most convenient way is to attach to such conduit the end of the tube 12 leading from the bag 13 of an ordinary fountain syringe, as shown in Fig. 1, the tube having the usual controlling valve 14 to regulate the flow of water into the holder 1.

To use the apparatus the holder is inverted from the position shown, the stopper 3 is removed and the desired quantity of oil introduced to the holder, after which the stopper is replaced tightly, and the nozzle and water supply connections being in place the holder is turned up into the position shown in Fig. 1, the level of the oil being indicated at 15, normally below the mouth of the conduit 5. Now it will be obvious that the oil will fill the tubular stopper and its head 4, but is prevented from passing into the tube 12 by the water from the bag 13, the valve 1 14 having been opened prior to inversion of the holder 1, and the holder may be moved about without any possibility of the oil escaping until the flow of the water is established. When the valve 11 is opened the water flows into the holder through the stopper 3 and displaces the oil, the latter rising in the holder until it overflows into the long part 5 of the outlet conduit and passes thence through the outer part 6 and 7 to the tube. and out through the nozzle, As the Water, isheavier than the oil the lat ter is lifted and gradually displaced by the Q incoming water until all, or as much as de sired of the charge-of oil in the'holder has been discharged, whereupon the valvefll' is closed, the apparatus removed and the tube 12 detached. The restof the apparatus is then emptied and cleaned by boiling or otherwise, as may benecessary. It willbe observed that the apparatus is perfectlyclean in use, is at all times under;

rubber bag syringe can beused in connection therewith for oil irrigation Without any danger of the oil; COIlllYlglH contact with the rubber, and the use of pistons, compresslon bulbs and other similar apparatus is. obvi- I 1 name to this spec1fic'at1on,'1n the presence of ated. 7 r

Having fully'described my invention, what I claim as new and desire to secure by Letters Patent is 1. In apparatus of the class described, an 7 vinvertible oil-holder having a filling op'ening, a removable tubular stopper closed at and terminating near the bottom thereof, a

nozzle tube connected with the outer end of said conduit, and a source of water supply connected with the tubular stopper externally t0 the oil-holder and communicating with the interior of the oil-holder by the tubular portion of the stopper surrounding the outlet conduit.

2. In'apparat'us of the class: described, an

elongated invertible oil holder having a filla ing opening, a removable tubular stopper t0 tightly close the opening and having a globular; head, an inlet conduit communi vcatingwith the interior of the head and stopper, 'an oil outlet conduit extended throughthe head andstopper and terminat- 3 ing Within the holder near its bottom, the

opposite end of said outlet projecting be-.

' yond the head, a nozzle tube'connected with said'projecting end, and a source of Water supply connected with the inlet conduit.
