HORACE WARREN PARSONS, OF WAMEGO, KANSAS.

STOMACH-PUMP.

SPECIFICATION forming part of Letters Patent No. 386,603, dated July 24, 1888. jXpplication filed October 11, 1887. Serial No. 251,977. (No model.)

To all whom it may concern:

Be it known that I, Horace Warren Parsons, of Wamego, in the county of Pottawatomie and State of Kansas, have invented a new 5 and useful Improvement in Stomach-Pumps, of which the following is a full, clear, and exact description.

This invention, which is applicable to various surgical and other operations, consists in io a novel apparatus for the purpose of washing out and removi ng the contents of the stomach, bladder, or other cavities of the body; and it comprises special constructions and combinations of parts, substantially as hereinafter 15 described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

_ Figure 1 represents a partly-sectional elevation of an apparatus embodying my invention. Fig. 2 is a broken longitudinal section, upon a larger scale, of a stomach-tube forming a portion of the apparatus, and serving to throw 25 fluids into the stomach to act as antidotes to poison and to remove the same from the stomach, whereby a cleansing-current is established through the stomach or other interior organ to which said tube may be applied. Fig. 3 is 30 a longitudinal section of the valvular portion of a pump forming a portion of the apparatus. 1

In the apparatus shown in the drawings, A ( is a reciprocating plunger-pump, the piston ¹or plunger of which may be operated by a 35 treadle, b, through a pitman, e, and crank upon a main shaft, d; or said pump may be otherwise driven—as, for instance, through a drivewheel, d'. Said pump, which is an oscillating one, is carried by a flat spring, e, projecting 40 upward from any suitable base or support, and which, being attached at its upper end to the pump, provides for the vibration or oscillation of the latter, as required. This pump is driven by a crank or face-plate, /, the wrist 45 to which the piston rod Λ is attached being marked g. The wrist g is applied to an arm or plate, i, which is pivoted, as at λ:, on the faceplate, so as to vary the distance of the wristpin from the center of the face-plate or its 50 shaftiZ, there being any number of holes s, with which the wrist-pin, that may be in the form of a thumb screw, is made to engage; or the arm i, carrying the wrist-pin, may be otherwise adjustably secured upon the face plate. The apertures s—one of which may be in the 55 center of the face-plate/and the others at different distances therefrom—serve,accordingly as the wrist-pin is adjusted in relation with them, to vary the length of the stroke of the pnmp, or, when the wrist-pin is in line with 60 the central one of the apertures s, to arrest the action of the pnmp altogether without stopping the motion of the driver. This adjustable arm or plate i and face-plate/constitute what may be termed an “adjustable crank.” 65

The pump A, which may be otherwise constructed and operated, if desired, has opposite side nozzles, 1I', fitted with valves m m', and the one of which, Z, is an exhaust-nozzle, while the other, Z', is a discharge-nozzle. 70

B is a stoppered receiver, with the upper space of which the exhaust-nozzle I is connected by a tube, C, that may be more or less flexible and be in any number of pieces. D is a close flask or vessel, with the upper space of 75 which the other or discharge nozzle, Z', is connected by a tube, C', as shown, or in any other suitable manner—as, for instance, as the receiver B is connected with the nozzle Z_the tube 0' also being more or less flexible and be- 80 ing made in any number of pieces.

When the pump is at work, it operates to exhaust the air from the receiver B and to discharge it into the flask or vessel D.

The receiver B, which serves to receive the 85 contents of the stomach or other organs under treatment, may be stationary and only requires to be removed when it is necessary to empty it; but the flask or vessel D, which contains the fluid used in washing out the stomach 90 or other cavity or organ, should be readily removable and may rest in a support,E. When constructed as shown, the flask D may be inverted for the purpose of filling it.

F is the stomach-tube,or rather double-cur- 95 rent tube, applicable not only to washing out the stomach, but other cavities or organs of the body. This tube is a compound one, the same being composed of an inner tube,»', and an outer tube, V, arranged to leave a space in ion between them. At the one end of these tubes is a perforated nozzle, c', which virtually

386,603 forms an extension of the inner tube, a', and which is perforated, as at e', to receive the contents of the stomach or organ being operated on through it and out through the tube a', and from thence by a tube, G, to pass said contents into the receiver B,the tube G, which connects with the outlet end of the tube a', passing at its other end through the stopper in the receiver B and opening into the upper io space of said vessel. The inner tube, a', is a rigid one, so that it will not collapse when exposed to the vacuum in the receiver B, with which it connects; but the other tube/',should be made soft and yielding to permit of a free 15 passage of the washing-tluid through it and out in the form of a spray or small streams, through perforations e² near the inner end of said tube, into the stomach or organ under treatment. This outer tube, b', is closed at its 20 ends, but is provided at or near its receiving end with a branch or nozzle,/', with which a tube, H, connects. This tube H passes into and through the bottom of the vessel D, to establish communication between the washing25 fluid in the lower portion of said vessel and the tube b'.

The operation is as follows: Supposing the flask or vessel D to be charged with any suitable or washing fluid and the double-current 30 tube F to be applied to washing out the stomach, then when the pump A is set iu motion it will exhaust the air from the receiver B and force said air into the upper portion of the vessel D.
