IMPROVEMENTJINSTOMACH AND ENEMA PUMPS.

Specification forming part of Letters Patent No. 207,072, dated August 13, 1878; application tiled June 20, 1,873. Y

T0 all whom it may concern:

Be it known that I, ENRICO RosENzI, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Syringe Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a vertical section. Fig. 2 is a top plan, and Fig. 3 is a horizontal section on the line a' x, Fig. l.

Similar letters of reference indicate corresponding parts in all the figures.

This improvement relates to pumps or syringes used by the medical profession; and it consists in the construction and combination of parts of a combined stomach (or suction) and enema (or injection) pump or syringe, substantially as hereinafter more fully described.

In the drawing,Ais the base board or block, upon which is secured the chamber B and receiver or reservoir C, which are united by a` short tube, b, having a stop-cock, a. The top of chamber B has a screw-threaded sleeve, c, into which is screwed the screw-threaded nozzle el of the piston -pump D. Besides the perforation to receive tube b the cylindrical wall of the chamber B has two other perforations or openings, e f, connecting with the tubes E F, respectively, the former of which projects from chamber B in a straight line, and has a stop-cock, e', while the latter is bent at a right angle to form an elbow, which is also, at the end of its vertical arm, provided with a stop-cock, f1. The bent exhaust-tube F has a small opening, f2, on one side, above the stop-cock f', for the purpose hereinafter stated.

The receiver C is a cylindrical vessel secured upon the block or standard A, and having a valve, g, on one side, near the bottom, which connects with a short tube, G, having a stopcock, g. Through the ccnterof the removable cover G', the annular screw-threaded flan ge of which screws into the screw-threaded rim of the receiver C, is inserted a vertical pipe, Il, which reaches down close to the bottom ot' the receiver, as shown. Pipe 71, communicates with a short vertical tube, H, provided with a stop-cock, z'. Upon the base-board A is secured a meta-l box, I, with a hinged cover, which contains the nozzles, mouth-pieces, and other attachments of the apparatus when not in use, so that these may always be handy and ready for use or exchange, according to the purposes for which it is desired to use the apparatus.

When this apparatus is to be used as a suction-pump to relieve the stomach and iutestines from oppressive gases, a piece of flexible tubing of suitable length is secured upon tube E of the chamber B, and a suitably-shaped mouth-piece is secured in the other end of the tube and inserted into the rectum of the patient. The stop-cocks e and f1 are then both opened, but a is closed, and the pump D having been screwed into the chamber B, so as to form an air-tight connection therewith, the apparatus is ready for` use. By raising the piston-rod and piston D the gases are drawn through the flexible tube and tube E into the chamber B and pump D, and expelled by depressing the piston through the small opening f2 in the elbow-tube F.

To use the apparatus as. an enema pump or syringe, the stop-cocks c f1 are both closed and a opened, and a ilexible suction-tube is secured upon the mouth-piece G, whose stop* cock g is also opened. Next, another exible tube is securedupon the vertical mouth-piece H, into the other end of which is inserted a suitably-shaped nozzle, according to whether the apparatus is to be used as a clyster, vaginal syringe, ear or nose syringe, &c. By raising the piston-rod and piston D the fluid is drawn into the receiver through tube G and valve g, and by reversing this motion and depressing the piston theiluid is injected through pipe 11 mouth-piece H, and the flexible tubing and nozzle with which this communicates. By closing stop-cock t" the receiver may be filled with the iluid (either hot or cold) before the operation of injecting it is commenced, or it may, if too hot, be left in this receiver, which may be wrapped in wet cloths or surrounded by pounded ice to cool. By connecting the inlet-pipe or mouthpiece G with a small boiler, such as are used by the medical profession for injecting steam, medicated or otherwise, steam may be injected through the receiver C instead of fluids.

To use this apparatus as an ordinary clyster for a single charge or injection, the pump D is unscrewed from the chamber B, and a suitably-shaped mouth-piece screwed upon its screwthreaded nozzle, when it is ready for use.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. The combination of the pump-cylinder D, piston D' and its rod, chamber B, having the inlet tube or pipe E, and cock e with the pipe b, havinga cock, a, cylinder C, provided with an internal tube surmounted by a valve, g,

pipe d, pump-cylinder D, its pistonD and rod,

substantially as and for the purpose specified. In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
