APPARATUS FOR SURGIGAL USES.

Application filed. May 17, 1924. Serial No. 713,878.

To all whom it may concern.

Be it known that I, ANGELO L. Sonnsr, a citizen of the United States, and resident of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Apparatus for Surgical Uses, of which the following is a specification.

This invention relates to an apparatus forsurgical uses, and more particularly has for its object to provide an improved device of simple construction, one which may be readily sterilized and one which may be subjected to continuous operation during its operation.

More particularly it embodies means which are interchangeable, and also means for holding the balls which act as valves under restricted movement control, which balls act also under the action of gravity, the apparatus when being used being so placed as to invoke the action of gravity in its operation.

The invention will be more fully described, hereinafter shown in the accompanying drawings and finally pointed out in the claims.

In the accompanying. drawings,

Figure 1 is a perspective view of my improved apparatus.

Figure 2 is a central verticalsection of a part of the same.

Figure 3 1s a section takenon line 33 of Fig. 2, and i i Figure 4 is a section taken on line 44 of Fig. 2.

Figure 5 is a section taken on line 55 of Fig. 2. Similar characters of reference indicate corresponding parts throughout the various views. V

Referring to the drawings and more particularly to Figure 1, my improvedapparainstrument to be raised or lowered so as to adapt it to the syringe.

The syringe is of well-known construction, consisting essentially of a tubular or cylindrical member 21 closed at 22 and 23, the closure 23, having an opening communicating with the taper joint connection 24. A piston 25 operated by the handle 26, pass ing through an opening in the closure 22 acts as a pump.

The instrument itself consists of a casing 30 which is bored out symmetrically at the upper and lower portion thereof in substantially conical shape. Into these conical cavities there are inserted members 31 and 32, which are interchangeable. The

member 31 has a shoulder 33 and a conduit channel 34, having an enlarged'portion 35 and an outlet portion 36. Over the shoulder 33 a screw cap 37 is provided, which engages the corresponding screw threads of the casing 30. The member 32 is similarly arranged, its extension 20 seating in the standard 16 and being held by the thumb screw 19. The casing 30 is further provided with a center bore acting as a conduit, indicated by 39, and this has a lateral channel 40 communicating therewith, which is of tapering shape and forms the interior of the member 24 attached to the pump cylinder 'hereinbefore referred to.

The casing is further provided with a conical seat 41 for the upper .ball valve 42 and at the other end of the conduit 39 the casing is providedwith a cavity 43 which permits the lower ball 44 to move therein. It will be notedth at the seat 41 tus comprises a frame or standard 10, consisting of a vertical member 11, having three lateral brackets 12, 13 and 14, either secured thereto or made integral therewith. The two lower brackets 13 and 14 serve in part the function of attaching the apparatus to a table or the like and for this purpose a clamp screw 15 is provided. The bracket 13 serves the further purpose of supporting the standard 16 on which the instrument rests. The bracket 12 supports the syringe 18 of the instrument. Suitable thumb screw 19 serves to enable the portion 20 of the and the cavity 43 are quite close to each other. In other words, the channel or conduit 39 is of relatively short length. It will also be noted that the cavities permit a limited freedom of movement to the balls, which however, are restricted in their move ment. Gravity acts to cause the balls to descend to their seats. No springs are used.

To the end 36 of conduit 34 a tube 34 to which a needle is applied may be readily. attachedand when used this tube and needle serve to convey the blood or other fluid to the recipient. The other, or inlet member 36 may have a tube 36 attached thereto, also provided with a needle,

1 and, forces, by pressure; the blood through inserted into a container holding the fluid. If the apparatus is used for drawing pus or the like from a body, then a needle is applied to the tube attached to the inlet end 36 and the needle on the tube 34 is dispensed with.

The operation of my improved device for blood transfusion is as follows After the device, and tubes. and needles have been thoroughly sterilized, the needle of the tube 36" engaged with the inlet 36- is inserted into the donor and then the needle attached tothe tube 34, is inserted into the recipient. The pump is then actuated. The actuation of the pump by its suction, serves to raise the ball at fromits seat against the action of gravity and thereby the blood is drawn through the conduit and into the cylinder of the syringe or pump,

the other ball 42 being drawn tightly by the suction created against, its seattl, being aided by the, action of gravity. The counter movement of the piston of the syringe or pump then presses the ball 44 against its seat being aided by gravity, raises the ball 42 from'its seat against the action of gravity,

the conduit 34, out ot the outlet 36 and through the needle into the recipient.

It will be noted that the casing 30. is arranged in vertical. position, as a result of which the ball's ..44 and-42 are underthe movement in the vertical direction against the. action of gravity 1s- ,overcome by the afction'ot gravity at' all times and. their.

suction of the pump in'the one case; and by thepressure. of; in the; other case, It is essential to place the apparatus in vertical position, as otherwise it willfiot work.- This. is. very" important since the actionof the device takes into consideration the-action of gravity. The; operationdescribed is, repeated by theaction of? the piston in the; pump orsyringeand as a resultthereof a continuous transfusion. ot the blood takes place from the donor to. the recipient. The actionisimmedi'ate an-drap'iid and the blood so transfused is not subjectedto inject-ion,

but. on .the contrary the instruments and parts thereof act inthe nature of a contin-. uous communication between donor and recipient.

Preferably in such. cases where fluid is injected, the needle orifice of the recipient is smaller than that of the donor, whereby in the tube'atth-e recipient end air accummulated pressure results, which aids in the injection! The action of the device-is very positive and-quickly responsive to the movement of the syringe... After the blood has been transfused, the needles are extracted, the. instrument is -.I cleaner-l5, and it is then. ready for another USE,

The device hasthe further adianta ge that it maybe readily cleaned, in that the caps 37 and 37 are removed and the members 31 and 32, as also-the casing, are then subjected to, an intense sterilization. After this, they are again assembled and the device is ready for, further use.

It will be particularly noted that the action of the balls is under the force of gravity that the balls are in restrictedcavities which limit the movement of the balls.

I have described the use and the operation of my improved apparatus in connection with blood transfusion- But the apparatus may also be used for hypodermoclysis,thoraneedle is applied to the inlet tube which needle is then inserted in the locality desired tobe treated, and the outlet tube then acts only as a discharge tube of the matter extracted from the body. In hypodermoclysis, infiltration and intravenous injections, the inlet tubev has its needle removed and is inserted into a container holding the fluid to be utilized andthe' outlet tube has applied thereto its needle which is inserted into the body. As before stated, insuch cases where fluid is injected into the human body it is advantageous to have: the orifice of the. inlet opening or the orifice of the inlet tube larger than theorifi ce of the outlet tube, or in other words, larger than the orifice of the needle. In view thereof an. accumulated pressure is obtained. so thatlgwithj each action of the pump the accumulated pressure assists in i ljficling X the fluid into thef'hiiman body,

against the pressuresthereinpresent; It has necessary. In the device hcreinbefore described and shown in the drawings the pump or syringe is relatively small and comparativelylittle effort on the part of the operator is necessary, the reason for this being the simplicity of the operation of the parts, particularly in that the balls are restricted in their movements. and in certain positions are aidedby the acts of gravity and also by the accumulated pressure reservoir within the conduits, hereinbfore' described. In iew thereof, my device can'be readily manufactured, is of comparatively small size, and hence can be made at very little expense.

I have described one embodiment of my invention but do not wish to be limited in the details thereof since changes may be made without departing from the spirit of the. invention, as defined" in the appended claims.

I claim as new:
