NEEDLE HOLDER AND sTERILIzEE Filed June 30. 1944 [Al/Inna i Resume/ca Gown/5e.
Patented Nov. 23, 1948 NEEDLE" HOLDER AND I STERILIZER,
Frederick F. Gunther, Ohicago, Ill., 'assignor to xhlixelalmco, Inc :Chicago, Ill.,:a corporation of Il- Application uneso, 1944,.seriai N o. s4a95e v This invention: is directed to 'a holder and dispenser for hypodermic needlesand-relates more particularly to a dispenser which may hold the needles during a sterilizing operation.
In the use ofneedles for hypodermic syringes,
itis wel1 known that the greatest problem involved is that of sterilization. It has been found that it is impractical to .sterilize -each needle before each use particularlyon-occasions where mass injections are performed as is the casein preparing the armed'forces for combat duty. On the other hand, itishighly desirable that anumber of 'needles be sterilized and then maintained in readiness for use "without further handling which results inrecontamination.
In thepast it has been the custom to' insert the point of a sterilized needle into a soft, presumably sterile materiarsuch as-cork or-th like. This is accompanied by several disadvantages. First-the cork is often not steri1e-as believedand furthermore it is found that smallparticles of cork are forced'into the-hollow needle and later injected into the patient.
It has also been thecustom in 'the pasttosterilize a large quantity of needles and then store them in a' 'containerin which theyare disposed in random fashion;necessitating handling thereofas they are attached to the syringe.
It is an object of the'present invention to provide a novel, cheap, efiicient needle holder and dispenser into which cleaned and "sharpened needles maybe disposed whereupon the entire assembly-may be subjected to; a= sterilizing opera tion and may 'beleftin the "sterilizing atmosphere until one or more of theneedlesis used, the needles thenbeing available for attachment to the syringe without the-"necessityof theirbeing handled and again contaminated.
It is another object ofthe present invention to provide-an improvedneedleholder and dispenser so constructed-that the-needles mayfbe inserted and locked therein and when-so locked the, entire assembly maybe handled-with no'further thought to the loss of the needles since they are mechanically retained therein and'when exposed maybe applied tothe syringe withoutbeing touched by thehand. I l
It, is another object of the presentinvention to provide in a'Jneedle.holderuand-idispenser. a dispensing member or? base which isaperturedto receive therethrough the :shanks of the needles and to support the same by means of the enlarged heads thereof, ,,a cover for disposition over the needles, and again'st' the.l PP r: ends or the heads thereofwher'eby the. needles are; prevented from r .7 Claims. (Cl. 21%91) longitudinal movement in the apertures, and
means for securing the cover removably in position over the needles.
It! is still a further object of the present invention to provide-in aneedle holder and dispenser of the above character, a lower base portion of sheet material or the like having apertures in the upper surface thereof forloosely receiving theshanks of needles and supporting the same by the enlarged headsthereon, this base being provided with suitable means for interlockingly engaging a cover member adapted to extend. over the upper ends of the heads of the needles adistance approximately the height which the heads of the needles extend above the apertured part of the base, thereby to securely lock the needles Within the base when the cover is attached in the assembly; and to render the needles, and particularly thelheads thereof, freely accessible for engagement with-the needle attachments on syringes when the cover is removed therefrom, this entire assembly being susceptible of sterilization as -a unit andto be maintained in sterile condition until all of the needles are removed.
"It is another object of the present invention to provide a-needle holder and: dispenser of the above character-in which the'base memberis provided with a depending skirt whereby the shanks of needles in'the base are protected against breakage at the polntsthereofyso long as theyare-shorter than the skirtron the base or the supporting adjunct thereof when the base structure is utilized as a-stand from which the needles maybe dispensed.
While the embodiment herein is shown and described as utilized for sterilizing, supporting and dispensing hypodermic needles, itwill be understood that it maybe equally well utilized for otherarticleswhere its advantages are desirable. Many other objects and advantages of the invention will become apparent from the following "description and accompanying drawing in which:
"Figure 1 ma transverse, cross-sectional view of a holder and dispensing unit and a sterilizing unit embodying thefeatures of my invention;
Figure 2 is a plan view lookin down upon the structure of Figurel when the sterilizer cover is removed;
Figure 3 is a plan view looking down upon the structure shown in'Figure 1 with the sterilizer cover and the dispenser cover removed;
Figure 4jis-a fragmentary, enlarged vertical sectional'view of a .portion of the base showingthe manner in which a needle is supported thereby; and
Figure 5 is a transverse, cross-sectiona1 view partly in elevation of a modified form of my vention.
It will be understood that the embodiments shown herein are for illustrative purposes only and may be changed or modified without departing from the spirit and scope of the invention as set forth in the appended claims.
In the construction shown in Figure 1 there is provided a sterilizer base Iii, here shown circular in configuration. Mounted upon the sterilizer base i is a sterilizing liquid container ll having a skirt 1?. formed to fit over the upper part of the wall of the base H1. The skirt l2 and the wall of the base I!) may be secured together by a press fit and further may gether if desired.
The sterilizing liquid container II is 'further provided with a radially inwardly extending flange l3 merging into a radially inwardly stepped portion l4 which in turn merges into .a depending, radially inwardly disposed liquid container 15.
To the end that liquid within the container l5 may be readily heated and vaporized a suitable filament 16 may be wound therearound and connected with a source of electrical current H.
To the end that the sterilizer may be completely closed during the sterilizing operation and for later maintaining the sterility of the sterilized needles, there is provided a sterilizer cover including a dome part l8 having an upper handle l9 and a radially outwardly extending flange 20 terminating in a depending circular skirt 2|. As will be seen from Figure 1, the flange 20 seats on to the flange 13 of the container portion and the depending skirt or flange 2! seats around the outer side of the flange l2, whereby the cover is securely maintained in substantial sealing engagement on the assembly.
The needle holding and dispensing assembly, as will be seen presently, is arranged to be set within the sterilizer described above and over the liquid bath therein, this relationshipbeing maintained by disposition of a circular part of the holder assembly within the stepped portion l4 immediately above the liquid container portion |5.-
This liquid holder and dispenser includes a dispenser member 22 having an upper plate-like part 23 bordered by a depending skirt 24Which may be of any desired depth, depending upon the size of needle to be accommodated-and the size of the sterilizer with which it is to be associated. The part 23 of the dispenser is, as shown in Figures 1, 3 and 4, punched to provide a plurality of apertures eachbeing bordered by a depending circular skirt 2.5. Thus it will be seen that when the shanks of hypodermic needles 23 are extended through the apertures so formed-the neck portions thereof fit against the depending circular flanges 25 in each aperture to provide a relatively secure mounting for each needle.
From the foregoing it will be seen that so long as the device is maintained upright in theposition shown in Figure l, the needles are retained in the dispenser device in an orderly manner. Furthermore, it will be seen that they are 1005613 fitted within each of the apertures, whereby the physician or technician need merely move the attachment part of a syringe downward-1y upon the device and insert thesaid part in the tapered orifice of the needle head. The further application be spot welded toof a slight amount of pressure securely fits the needle onto the syringe and the physician or techholder member 40 nician then performs the injection without the needle having been contaminated by handling. Because of the desired loose fit of the needle in the dispenser 22, however, it will be seen that should the device be accidentally tipped or handled,v the needles will immediately fall from the positions shown in Figure l requiring further handling and thus recontamination to again position them within the device.
- To the end that the needles may be securely, yet loosely maintained as shown at all times except when being withdrawn by the attachment part of the syringe, there is provided herein a novel arrangement for holding the needles in position which maybe itself handled, without contaminating the needles, to remove the same from the assembly.
This holding arrangement as shown herein in cludes an upstanding central post 2'l which is suitably secured as; by a screw 28 to the central part of the dispenser member 24. The post 21 is provided with an intermediate groove 29 and a mob-like handle 30 at the upper end thereof. The holder device proper includes a plate-like cover 3! which may, if desired, be provided with an upstanding flange 32 'therearound, the part 3| being apertured centrally as at 33 to receive the upper part of the post 21 therethrough when the cover is disposed in overlying relationship to the tops of the heads of the needles 26. When in this position it will be seen that the groove 29 of the post 2'l extends immediately above the upper surface of theplate part 3| thereof.
In order that the holder may be detachably secured in the position shown in Figure 1, it is provided that a spring member having resilient arms 3-l secured together at their lower ends and terminating near their outer ends in cross pieces 35 which in turn terminate in ring handles 33. This spring member may be secured to the plate part 3i in any suitable manner, but in the present instance is provided with ear-like portions 31 at the end remote from the handles 33 which extend through apertures in a skirt 38 of a circular I while the resilient arm portions 34 extend through an aperture in this skirt 38. The member 40, as will be seen from Figure l, is suitably secured to the plate part 3| by means of a suitable rivet 4 l. 7
With the above arrangement it will be seen that one need merely compress the handle portions 36 together, whereupon the resilient arms 34 are spread out of engagement with the groove 29 while release of these handles permits the arms L 34 to engage in the groove and securely maintain the holder over the tops of the needles as shown in Figure 1. a
In the construction shownin Figurev 5, the dispenser and holder arrangement is identical to that shown in Figure 1 except that in this form of the invention the skirt 24 is provided with studs 42 extending radially outwardly therefrom.
These studs 42 are for the purpose of suspending the dispenser member 22 in the upper part of a preferably transparent container 43 and may, rest upon the upper edge thereof as shown or may be connected thereto by a bayonet fit if desired. It will be understood, of course, that other mechanisms for securing and sustaining the dispenser member in a transparent container may be utilized.
Preferably the upper portion of the outer surface of the container 43 is threaded externally as at 44 to receive a threaded portion 45 of a cover or cap member 46. "The depth of the cap member preferably iscsuch that when screwed tightly onto the container 43-it abuts-the upper edge of the skirt 32 of the holder member, thereby to augment the action of the spring arms 34 in holding the cover member in position'over theupper sides of the enlargedheadsdofthe needles 26. When the assemblyiis secured togetheras shown in Figure 5,-it'wil1 be seem-that theneedles will be securely:maintainedrintposition in i'the'ievent that the holder'is tipped, rolled oriplaced up-side-down. V Furthermorefithe gpa'rticular needle which is desired, dependent upon the length of the shank thereof, may be determined before the container is opened so that that needle may be immediately and quickly attached to the syringe to enable the container to be again closed.
In using the construction of Figure 5 it is contemplated that both the container 43 and the cap 46 will be sterilized along with the dispenser, the holder and the needles, whereupon it can be assembled and taken into the field and used until all of the needles are contaminated by use. If desired, the container 43 may have alcohol or the like therein and the needles may be further sterilized by periodic shaking since the orderly position thereof will not be disrupted by such shaking.
It will be understood of course that in the construction shown in Figure 1, if electrical power is not available, any other suitable means may be used for heating the base portion of the sterilizer. This heating may even be accomplished over an open fire since the cover I 8 efficiently seals the interior from soot which might accumulate.
From the foregoing it will be seen that there is provided herein an improved dispenser, holder mechanism for hypodermic needles or the like, together with an improved carrier and sterilizing apparatus, this arrangement being such that the needles may be securely maintained, yet loosely maintained in the dispenser to be readily removed by the attachment part of a syringe. Furthermore, it will be seen that in spite of this loose engagement of the needles by the dispenser, the mechanism may be handled with little care, without fear of the needles becoming disarranged and thus necessitating further handling thereof.
