TEMPERlNG-BULB FOR SYRINGES, 80C.

SPECIFICATION forming part of Letters Patent No. 338,045, dated March 16,1886,

Application filed December 7, 1885. Serial No. 184,929.

To all whom it may concern.-

Be it known that I, THOMAS S. EASTON, of the city, county, and State of New York, have invented a new and useful Improvement in a Tempering Chamber or Bulb for Vaginal Douches; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which- Figure 1 is a side elevation, partly in section, of my improved tempering-bulb for vaginal and uterine douches; Fig. 2, a cross-section in line :c of Fig. 1, and Fig. 3 a detailed view illustrating the application of a three-way cock to the bulb.

It becomes important at times in medical practice to make use of douches which shall be varied in temperature during their application, and it is essential that exact degrees of temperature shall be observed and maintained in the douches.

To this end various forms of apparatus have been devised, in which streams of hot and cold water are made to mingle and are delivered in a single united stream of the desired temperature. These several forms of apparatus have, however, been connected in permanent form with water-closets, bath-tubs, or other water-supply fixtures of the house.

The object of my invention is to provide a neat device by means of which the tempera ture of the douche may be controlled and regulated with exactitude during its application and be positively determined by the constant indications of a thermometer, and which shall be portable, so as to admit of detachment for usein connection with any convenient source of water-supply.

My improved device is constructed in the form of a bulb having double induction-ports for a supply thereto of both hot and cold water, and a single discharge-port for the delivery of a single stream of tempered water to the douche, the induction-ports being governed by valves to control the supply from each, and which is fitted internally with a series of wings or deflecting-plates properly arranged to break up the fiow of water, and, by causing eddies and currents in the bulb, promote and insure a rapid and thorough commingling (No model.)

and blending of the two supply-streams, and which is provided with a thermometer adapted to indicate the mean temperature of the mingled streams to be delivered therefrom.

In the drawings, A represents a chamber or bulb constructed in any suitable manner of metal, hard-rubber, or other suitable material, preferably in the form of a hollow prolate spheroid. One end of this spheroidal bulbis provided with two induction-ports, B B, and with projecting nozzles O O, by which the bulb is connected with tubes D D, for a sup ply of -hot and cold water thereto, and these tubes are each governed by a valve ora cock, E, by means of which the supply from either tube is readily controlled. The opposite end of the bulb is provided with an eduction-port, F, preferably made of a diameter not to exceed that of either of theinduction-ports B B, and is fitted with a nozzle, G, connected with said port to facilitate the attachment to the bulb of a flexible discharge-tube, N, terminating in the douche-tube J, of any approved form.

K represents the tube of a thermometer which is fitted neatly within a longitudinal recess formed eXteriorly on one side of the chamber A, and which terminates at the end nearest the discharge nozzle G in an aperture, m, in the side of the chamber, large enough to permit of the introduction of the bulb K of the thermometer through it, so that said thermometer-bulb may project within the chamber. This opening at is covered and closed with a tight joint by means of a capplate, a, and an interposed gasket, 8, of rubber or other yielding material, the cap being secured in place by screws or other fittings.

The commingling of the two separate streamsintroduced'within the bulb from the tubes D D is promoted by means of wings R R, formed and fitted to project inwardly from the inner wall of the chamber A, said wings being so disposed as to break joint with each other and leave passages between them. As an equivalent for these separate wings, or as an auxiliary device in connection therewith, one or more transverse perforated diaphragms may be introduced within the chamber A, between the bulb K of the thermometer and the induction-ports BB.

The two induction-tubes may be governed by a Single three-way cock, T, (see Fig. 3,) instead of by independent cocks-E E, the cock being adapted, in the customary manner, to permit of an inflow from either tube alone or from both.

i The bulb A is preferably provided with a base-plate,W, by means of which it may be made fast to the wall by the side of a bath-tub, or may be laid upon the side plate of the tub or other convenient support.

In the use of my tempering-bulb the supply of hot and cold water to the chamber A is regulated by means of the valves controlling the tubes D D until the thermometer indicates the mean temperature in the stream flowing from the douche-tube J which has been prescribed. The change of temperature in the stream required during the continued application of the douche is then readily produced by a manipulation of the valves in the induction-tubes, whereby the prescribed indications upon the thermometer may be obtained, which will denote the temperature of the effective stream, and any required temperature constantly maintained so long as may be desired.

I am aware that an apparatus for giving injections at regulated temperatures, in which a being controlled each by a suitable cock, is

not new; hence I do not claim, broadly, such a device.

My invention relates to the special internal construction and portable form of my device as described; and

I claim as my invention- The combination, with a tempering-chamber for a vaginal or rectal douche constructed with double induction and a single eduction port, a valve controlling each port, and a flexible delivery-tube fitted to the eductionport, of deflecting wings or diaphragms fitted within the chamber to produce a commingling of the infiowing streams. substantially in the manner and for the purpose hereinset forth.

In testimony whereof I have signed my name I to this specification in the presence of twosub--' scribing witnesses.

A. B. MOORE.
