VTILLIAM GRAHAM PAINTER, or BIG sroNneAr, vrnerniA, Assrenon or one- 1,572,075 n-11 1511), STATES PAT T OFfFiiCE- HALF T FRANK NICKELS, OF BIG STONE GAP, VIRGINIA;
SYRING-E ASPIRATOR.
.- Application filed May 10, 1924. Serial No. 712,396.
To all whom it may, concern 1 Be it known that'IflVILLrAM G. PAINTER, a citizen of the United; States, and a rssident of Big Stone Gap, in the county of Wise and State of Virginia, have invented certain new and useful Improvements in Syringe Aspirators, of which the following is a specification.
This invention relates to a, syringe aspirator, and the object of the invention isto provide an instrument of this gcharacter which makes possible the aspiration of fluids from, and theinjection of medicated fluids or other fluids into the veins, arteries or other cavities of the human body without the necessityof employing the cumbersome apparatusordinarily employed, without the loss of time usually experienced, and with out necessitating the removal of the needle from the patient or subject or from the in strument until theop'eration has been com pleted. i. v 1 I i A further object is toprovide an instrument of this character and having these advantages and capacities. and which is of simple and durable construction, reliable in operation and easy-and comparatively inexpensiveto manufacture;and which requires but fewand simplemanipulations in carry ing out its manifold purposes. I Other objects and advantages of the invention reside in certain novel features of the construction, combination and arrange mentof parts which will behereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawing.
forming part of thisTspecification, and in which:
Figure 1 is a view partly in side elevation and partly in longitudinal central section, showing one embodiment of the invention with its parts in one position;
Figure 2 is a view similar to Figure 1 but showing a different position of the parts;
Figure 3 is a group in perspective, illustrating the several parts of the instrument;
Figure 41 is a view in section on line ia of Figure 1; and
Figure 5 is a similar view on line 55 of Figure 2.
Referring to the drawings, the numeral designates an outer barrel of cylindrical form having its forward end closed by an integral end plate 11 and having its rearward end open, In the end plate 11 a plurality ofports, designated at 12 and 13 are provided and these ports are arranged at spaced angular mtervals around the periphery of the end plate 11., Each of the ports 12 and l3e are designed to serve as in take and discharge portsas will presently appear. Nipplesl l and 15 surround the ports 12 and 13 and providemeans whereby rubber tubing or, needles or canula may be connected to the outer 'barrel.
An inner barrel 1 6 of cylindrical form is Preferably the inner periphery of the outer barrel 1O andthe outer periphery of the inner barrellG are formed to-provide a ground and fluid tight joint to prevent the fluid from escaping from between the barair between the barrels.
tegralend plate 17 having asingle port 18 lrotatablylfitted within the outer barrel 10.
formed therein. The, port 18 is adapted to be selectively registered with the- ports 12 and 13 when the barrel 16 is shifted or rotated relative to the barrel 10. y
In order to insure registration of the port- 18 with either the port 1201' the port 13 in the extreme position of the barrel 16 with respect tothe barrel 10, a collar 19' is fixed thelportion of the barrel 16 which pro- JGCCS, from the barrel 10 when the barrel 16 has been inserted as far as it may be inthe" barrel 10. This collar 19 has integrally formed therewith a 2stop-lug2O which op crates in an arcuate slot 21 provided in the rear ard endof the barrel lO. When the lug 2Q engages the end wall 22 of the slot 21, the port 18 is in registry with the port 12, as shown in Figure 2 whereas when the lug is engaged with the end wall 23' of the slot 21 the port 18 is in registry with the port 13, as shown in Figure A piston 25 is slidably fitted in the inner barrel 16 and has a ground joint therewith so that escape of the fluid past the piston or escape of the air past the piston is preprovided between the relatively movable parts of the instrument are intended to be such that any fluid that passes into the in terstices between the parts will be so wide- 1y distributedand will encounter such great resistance as to prevent leakage under the pressures encountered.
With this arrangement a. needle or canula may be connected up to the nipple 14 and if the device is to be used as an aspirator the barrel 16 is rotated 'to bring the port 18 into registry with the port 12 with the piston fully inserted in the barrel 16. Then when the piston is withdrawn fluid will be aspiratedfronrthe patient or subject to fill the barrel 16. hen the barrel 16 has been filled it is shifted or rotated to bring its port 18 into registry with the port 13 whereupon the piston 25 is pushed into the barrel 16 to discharge the fluid through the port 13. When the barrel 16 has been again shifted to bring its port 18 7 into registry with the port 12 a second 'as the patient or from the instrument.
pirating actionmay be had. This operation may be repeated as often as may be necessary without removing the needle from the body of the patient or subject and without removing'the needle from the instrument. 1
hen the fluid is to be injected into the patient or subject the nipple 15 has its hose immersed in the fluid and the nipple 14 isconneoted to the needle as before. By first bringing the port 18 into registry with the port 13 and with-drawing the piston 25 the barrel 1.6 may bejiilled with the medicated fluid; and shifting thebarrel 16 to bring its port 18 into registry with the port 12 and by then pushing the piston 25 inwardly, the fluid may be injected into the patient or'subject. As in the case of the aspiration operation, the injection may be repeated as often as inay'be necessary without removing theneedle from the patient orfrom the instrument. In fact these two operations may be made to follow each other without removing the needle from Moreover, the parts may be easily and quickly manipulated and may be readily taken apart for cleaning.- and: sterilization.
It is to be understood that. the ports 12 I and 13, and 18 may be formed in the peripheral walls of the barrels 10 and 16,
" respectivelyinstead of in the end plates thereof. v I
