ATTORNEY Patented Feb, 19, 1953 UNITED TATES r OFFICE 19 Claims.
The present invention relates in general to hypoderic syringes, and more particularly to certain new and useful improvements in holders for hypodermic syringes to facilitate filling and diccharge thereof.
Users of hypodermic syringes are frequently patients who require regular, daily self administifation of medicinal preparations. Such persons often have great difiiculty in reading the small and somewhat obscure calibrations on the glass barrels of conventional hypodermic syringe and are constantly subjected to the hazard of making mistakes which can be serious or even fatal. The problem of providing some automatic stop means which will assist such persons in the loading of their syringes is complicated by the fact that the plunger of a syringe must be withdrawn preliminar-ily to 1111 the barrel of a syringe with a volume of air somewhat larger than the volumetric size of the dose to be withdrawn from the ampule or vial. With such quantity of air in the barrel the syringe is plunged through the soft, penetral rubber stopper in the endof the vial or ampule and the air expelled into the vial so as to set up a slight amount of pressure upon the medicinal preparation therein contained. Thereupon, the needle is Withdrawn slightly so that it is entirely immersed within the liquid and the plunger withdrawn, thereby sucking a quantity of V the liquid medicinal preparation into the syringe barrel. In
this operation, also, the syringe barrel is withdrawn to a point substantially beyond the dosage required and is then carefully pushed back returning a small quantity of the liquid medicinal preparation to the ampule or vial until the preci'se dosage is contained within the syringe. This procedure is considered highly important so that there will be no accidental inclusion of air bubbles within the liquid to be administered, otherwise the patient may suifer from an embolism which can conceivably be fatal. This manipulative technique makes it necessary that any non visual means for gauging the final quantit of the dose in the syringe must be arranged so as to become operative after an Of the preliminary steps have taken place and will function at the time that the plunger is pushed back to reduce the quantity of liquid in the syringe to the precise and correct dosage desired.
The primary object of the present invention is to provide a syringe holder of the type stated which incorporates an adjustable arm for coacti'OIl with the syringe plunger to facilitate drawing the correct dosage into the syringe so as to obviate the necessity for reading the graduations A further object of the present invention is to provide a syringe holder o'fthe type stated which embodies automatic means for injecting the needle into the users flesh and an adjustable needle guard for assuring that the needle will be properly positioned before injection, H
An additional object "o the present invention is to provide a syringe h ier of the type stated which is reliable and durable in use and econom icalin'constructidn. 7
With the above and other objects in view, my invention resides the novel features of form. construction, arrangement, and combination er parts presently described and pointed out in the claims. b

Referring now by reference characters to the drawings which illustrate practical embodiments of the present invention, A designates a conventional hypodermic syringe having a cylindrical barrel 4, fabricated preferably .101. glass, being open at, its upper end and provided at its lower end with an outlet nozzle or tip 2 over which is frictionally engaged the hub 3 of a hypodermic needle 4, :At its upper end the barrel i is provided with an integral collar or shoulder 5 and upon its outwardly presented face, said barrel 1 is provided with suitable graduated markings 8 for indicating the amount of dosage. The drawings herein, for purposes of illustration, show "a graduation in 40 units as commonly marked on syringes used by diabetic patients for i and projecting at itsfu p'pe'r end '1: is a plunger or piston '1 ha fig a creased neck portion 8 a d an e arged ea 9'. Provided for use was a some it is a syringe 3 holder It, fabricated preferably of stainless steel, or other suitable light metal, comprising an upper relatively narrow tubular sleeve 1 I having an inside diametral size suitable for freely accommodating the syringe barrel I. Secured, as by rivets, at the upper end of the sleeve II is a plurality of spaced flexible finger elements 12 for gripping engagement upon the collar for retentively securing the syringe A within the holder Iil. At its lower end the sleeve II is integrally provided with a flange I3 against the upper face of which bears the lower end of a compression spring I4 surroundingly positioned about the lower portion of the sleeve II and bearing at its upper end against the under face of a closure disk I5. The disk [5 is marginally threaded for engagement with the internally threaded upper end of a lower sleeve [6 disposed outwardly of, and in concentric relation to, the upper sleeve I I. The sleeve [6 is diametrally decreased, as at I I, to provide an abutment shoulder I8 upon which is normally seated the flange i3 of the upper sleeve I I. The lower portion of the sleeve 16 is internally threaded for engagement with the external threads of a ferrule I9 upon which is also engaged a knurled locking collar 20. The lower end portion of the ferrule I9 is provided with a pair of diametrally opposed, L-shaped bayonet slots 2| for lockingly receiving pins or bayonets 22 suitably secured to, as by soldering, and projecting outwardly from a tubular member 23. Mounted upon the tubular member 23 adjacent its lower end are opposed outwardly extending lugs 24, 24', for swingably supporting a vial-holding frame 25 by extension through the apertured upper ends 26, 26', respectively, thereof. The lower transverse section 21 of the frame 25 is centrally provided with an axially bored, internally threaded boss 28 for receiving an upwardly threaded thumb screw 25. Disposed within the frame 25 is a conventional type vial or bottle 34, such as an insulin-containing ampule, with its neck 3i extending upwardly into the tubular member 23 and provided with a conventional rubber stopper 32 having a relatively thin, easily punctured center 33 for facile penetration by the needle 4. The screw 29 may be adjusted to bring its upper end into tight abutting engagement against the bottom face of the ampule 38 to maintain it securely within the frame It will thus be seen that through the concentricity of the sleeves l I, I6, the ferrule 19 and the tubular member 23, the needle 4 will be in axial alignment with the center 33 of the ampule stopper 32.
Pivotally mounted on the face of the upper portion of the sleeve I 6 is a latch member 34, its lower end being beveled and turned inwardly in the formation of a tongue 35 which is biased by a spring 35 for normally projecting through an aperture 31 in th wall 33 of the sleeve l6. Diametrally opposed to the aperture 31 the sleeve wall 38 is an internally threaded, relatively small aperture 39 for engagement with the threaded end of a screw 40 having an enlarged, smoothsurfaced neck 4| and a relatively large head 42. The neck 4| of the screw 44 projects through a suitable aperture in the lower end of a channelshaped support arm 43 for pivotally supporting the same, and has encirclingly disposed about its face a coil spring 44 which abuts at its inner end against the sleeve wall 38 and at its outer end against the inwardly presented face of the arm 43. The upper end of the arm 43 is of sufiicient I (it) length to extend beyond the upper end of the sleeve I I when said arm 43 is swung into upward position (see Figure 2). Provided in the arm 43 is an elongated, longitudinal slot 45, through which outwardly projects a threaded lug 46 suitably secured, as by soldering, at its inner end to a slide arm 47 disposed within the channel of the support arm 43, and projecting outwardly thereof at its upper end which is bent perpendicularly and laterally inwardly, as at 48, to form a stop member 49, having an arcuate recess 50 in one of its side margins for normal abutment against the stem and neck portions of the plunger 7 (see Figure 5). A
Threadedly engaged on the outer projecting end of the lug is an adjustment nut 5| for maintaining the slide arm 41 in any selected position relative to the support arm 43, it being apparent that the limits of adjustment are determined by the length of the slot 45. Suitably marked or delineated upon the outwardly presented face of the slide arm 4'! is a graduated scale 52 in calibration with the particular scale provided upon the barrel I of the syringe A, for purposes appearing.
more fully hereinafter.
In usage, the vial-holding frame 25 with the ainpule 38, containing the particular matter desired, as insulin, is positioned upon the lower end of the ferrule I9 by lockingly engaging the pins 22 within the slots 2!. The syringe A is then inserted downwardly in the syringe holder I0 and held securely therein by the gripping engagement of the fingers i2 upon the shoulder 5, in which position, the needle 4 will penetrate the center of the stopper 32 and extend into the fluid in the ampule 34. The slide arm 41 is then adjusted so that th scale 52 thereon will be set in relation to the upper margin of the support arm 43 (see Figure 1) to indicate the required dosage. Thereon the nut 5i is tightened for maintaining the slide arm 41 securely in the selected position. The support arm 43 is then pivoted to prevent the stop member 45 from interfering with the substantial outward movement of the plunger i for drawing material from the ampule 30 into the barrel l. Upon the completion of the outward movement of the plunger 7, the support 43 is then swung to bring the stop member 49 into abutment against the stem of the outwardly drawn plunger I The plunger 7 is then pushed inwardly until the under face of the head 9 abuts against the upper face of the stop member 49, whereon the contents in the barrel I will be in the requisite amount. It will be noted that the excess material expelled by the syringe A upon the inward movement of the plunger 1 into abutting contact with the stop member 48 will return to the ampule 3!), thereby eifecting a marked economy. By use of the slide arm 43, the user need not watch closely the scale or graduations upon the barrel I each time the syringe A is filled, since once the slid arm 41 has been appropriately set, it may be usedcontinuously without any further checking of the scale. This feature is of extreme importance to habitual users with affected eyesight, such as diabetic sufferers who utilize hypodermic, syringes daily, many of whom, as a natural result of their disease. frequently have impaired sight.
After the barrel I has been filled, as discussed above, the vial-holding frame 25 with the bottle 30 therein, is removed-by disengagement of the pins 22 from the slots 2!, and outward pulling thereof to dislodge and clear the needle 4 from the stopper 32. Thereon the user grips the upper portion of the sleeve 1H :and pulls upwardly vfor compression of the spring :14 (see Figure 4 .In its upward travel, the flange l3 will be brought into contact with the tongue 35 of the latch 34, causing it thereby to rock outwardly for allowing the continued upward movement or the flange I73. Thereon the latch 35 will, through bias of the spring 35, be pivoted to swing the tongue 35 inwardly into abutment against the under face of the flange 13 to retain the spring Hi under compression. As shown in Figure 4, in this retracted position, the lower end of the needle 4 will be in elevated relation to the lower margin of the ferrule it which thus serves as 'a needle guard for engagement of the users skin. The user then positions the syringe .holder it) so that the lower end of the ferrule 59 will define the field of the desired location upon his body for the injection. Therein the upper end of the latch 54%, through finger pressure, is pivoted inwardly against the sleeve wall 33 to rock the tongue 3'5 outwardly from engagement with the flange 13 to release the .spring M, for eiiecting downward movement of the sleeve H which causes the needle 5 to enter the users flesh. The plunger 7 is then pushed inwardly to discharge the dosage contained in the barrel the support arm 43 having first been swung to remove the stop member .49 from contact with the plunger 1.
In order to control the amount of penetration of the needle 4 through the stopper 32 or in cases where a larger needle is used and it is necessary to assure :its retraction above the lower margin of the ferrule 19 for facilitation of injection, the
locking collar 2i! may be loosened and the ierrule 19 threaded upwardly or downwardly, as necessary, the requisite distance, and maintained in such selected position by tightening of the collar 28.
If desired, a modified form of syringe holder 53 may be provided for use with a conventional hypodermic syringe A, having a barrel i, nozzle 2',hub 3', needle l',collar 5, graduations t, and plunger with a neck 8 and head ii, said syringe A being in all respects similar to the syringe A above described. The holder member 53, comprises an elongated sleeve or tubular member 54 having a diametrally increased lower end portion 55 suitably provided with opposed outwardly projecting ears or lugs 56, 5 .3, for extension through the apertured upper ends of a vial-holding frame '25, which is substantially similar to the vial-holding frame 25 above described. Retentively disposed in the frame 25' is an ampule 38' containing the desired medication, with its neck 31' disposed within the lower portion 55 of the sleeve 5%, said neck ti being provided with a stopper 32' having a thin, easily penetrated center 33'.
Extending longitudinally downwardly from the upper margin of the sleeve 54 is a recess 51 for revealing the graduated scale 6'. Opening into the recess 51 is a transversely extending recess 58 with a relatively wide mouth 59 for lockingly receiving the lower outwardly projecting end to of a clip member 6! integrally provided with a split band 62 for encircling the barrel 1 and a finger member 63 extending upwardly therefrom for grippingly engaging the collar 5' to retain the clip 8! in position upon the syringe A.
Pivotally secured upon the face of the sleeve 52 is a channel-shaped support arm 43' having engaged therein a slide arm 4'! provided with a transversely extending upper end in the formation :or a stop member -49 for optional abuttin relationship against the stem :of the plunger 11. The support arm 48. and the slide arm 11] i'and their integral parts, are in all respects similar to the support arm 43 and. slide arm 47., above described.
In usage, the syringe A is inserted down wa-rdly into the sleeve 54 with the lower end so of the clip 61 passing through the recess 5! until it has reached a point adjacent the :mouth 59 :of the recess 58. In this position, the needle 4" will have penetrated the center 33' of the stopper 3'2 with which it is axially aligned, :a substantial distance into the ampule $31? for "easy :flow of the material therein through the needle 42, independent :of its :level. Thereon the syringe A is turned to efiect entry :of .thelower end 69 of the clip '61 into the recess 158 for retentively maintaining the syringe A during filling thereof, which is accomplished :by operation of the plunger ii, the slide arm ti" and "stop member 49', in the same manner .as described above in connection 'withthe syringe A. It is apparent that the :clip :6] will he so positioned on the syringe A that whenfiti's engaged in th'e recess 58, the .graduat'ions it of the barrel 1 will be viewable through the recess 57 After therequisite dosage has been drawn into th'ebarrel "l the syringe A" .is then rotated to disengage the clip 61 from the recess 58 and is"'then withdrawn from the sleeve 5 4., with the stop member 418 maintained in contact with the head 9" to prevent any untoward inward movement or the plunger 1" during rotation. The syringe A is thus :in ready condition for injection purposes.
It should be understood that changes "and modifications in the form, construction, arrangement, and combination of the several parts oil the syringe holder may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.
