United. States Patent DEVICE FOR HOLDING HYPODERMIC NEEDLES Jay Rose, New York, N. Y.
Application January 19, 1954, Serial No. 404,903
Claims. (Cl. 211--60) This invention relates to the cleaning of hypodermic needles andmore particularly to a device for holding the needles during the cleaning. This application is a continuation in part of my prior Patent No. 2,704,266, issued March 15, 1955.
According to my present invention, there is provided a holder assembly for supporting the needles in substantially vertical positions and means for preventing the hubs from revolving while the insides are swabbed or wiped with a rotary cleaning tool. It is important that the in side of the hubs be thoroughly clean as well as the needle-tubes. Whether a rotary brush or other means is used, the rotary movement against the inner surface causes the hubs to revolve and prevents thorough wiping, if provision is not made in the holder to prevent their rotation.
In my prior application I have described a cleaning process for the hypodermic needles which depends upon a detergent liquid for disintegrating and removing foreign matter on and in the needles. After sufficient soaking in the liquid it is desirable to swab or wipe the insides of the hubs. After this it is advantageous to have the needles inverted in the detergent liquid, the hubs being below the needle-tubes. This will facilitate drainage since the wider part would be underneath. For this purpose, my present invention also includes means for preventing the needles from falling out of the holder when the holder assembly with the needles therein is turned over or upside down.
One object of my present invention is to provide means in conjunction with a holder for hypodermic needles that will prevent the needles from revolving in the holder when cleaning their hubs with a rotary tool.
Another object is to provide means for preventing the needles from falling out of a needle holder when the holder with the hypodermic needles therein is turned over or inverted so that the hubs of the needles are below the pointed needle tubes and plunged in the detergent.
For a more complete understanding of the invention, reference may be had to the accompanying drawings, in which:
Figure 1 is a plan view of the holder assembly for the hypodermic needles embodying the features of the present invention,
Fig. 2 is a side elevational assembly with a portion broken away andshown in section,
Fig. 3 is an end elevational view,
Fig. 4 is a fragmentary sectional view showing the use of a wire mesh for holding the needles within the assembly, and
Fig. 5 is a fragmentary sectional view of the wire mesh frame by itself.
Fig. 6 is a perspective view of a modified form of the invention in which the spaces of the needle are provided in spaced non-channel pieces.
Fig. 7 is a fragmentary plan view of this form showing how the needle is retained between the pieces,
Fig. 8 is a sectional view taken on line 8-8 of Fig. 7, and
Fig. 9 is a sectional view illustrating a further form of the invention in which the non-channel pieces are of different section than that shown in Figs. 6 to 8.
Referring now to the form of the invention shown in Figs. 1 to 3, 1 represents a hypodermic needle having a hub opening 2 and fiat opposing side faces 3. A needle. holder assembly is formed of channel pieces 4, running in side by side parallel relationship with one another. Each piece has a series of spaced holes 5 for receiving the needles up to their hubs. The channel pieces. are held together in close assembled relationship with side plate 6 by threaded rods 7 passing through the ends of the same and clamped by wing nuts 8 on the opposite ends of the rods that are tightened against side plates 6. Fixed to and carried by the side plates 6 is a wire. handle.
and stand supports that extend upwardly and below the assembly and on which the assembly with the needles can be rested in the vessel 15 containing the detergent, either in its upright position or in its inverted position.
In Figs. 4 and 5, there is shown a screen 12 having a frame 13 and secured over the tops of the needles spring clips 14 that are fastened between the lower edges of the side plates 6 and the screen frame 13. By the screen 12 means have been provided whereby the needles are held in place when the assembly with the needles are inverted either to dip the hubs of the needles in the deter gent or for draining them. The side plates have the handles i secured to them by welding or other means. Before the threaded rods 7 are inserted in the holes of the side plate 6 the wing nuts 8 are removed from one end and then the other side. When the channel pieces 4 have been assembled on the rods the nuts are replaced on the threaded portions of the rod ends and tightened with the handle side plates to the channel and the plate into a rigid holder assembly. The holder assembly is now complete. The pointed needle tubes extending from the underside of their hubs are dropped into the openings 5 in the channels and the flat sided hubs will engage side walls of the channels so as to prevent the needles from being revolved.
A wire screen 12 is placed over the hubs after the needles are in the holder and are thus held in place by the metal clips 14. The needles cannot fall out of the holder assembly when the holder is turned over and the hubs are below the needle tubes. The openings in the wire are suflicient while holding the needle hubs to allow adequate entrance of the detergent to and drainage from the hub openings 2. In both positions the assembly is supported by the handle supports 9.
Instead of channels with openings, other means for supporting the hypodermic needles so that they will not revolve may be used, see Figs. 6 to 8. Pairs of opposing metal strip pieces 20 are held spaced apart by spacers 22 assembled on threaded rods 23 and held in close coupled parallel relationship by wing nuts 24. The lower por' tions of the pieces are inwardly bent to constrict the lower space or opening so needles dropped into the spaces will hang by their hubs therein. In the form shown in Fig. 9 pieces 20" taper inwardly to provide opposing diverging side faces 25 to constrict the lower space. In both of these latter forms the parallel side faces of the hubs engage the side faces of the strip pieces 20 or 20' to prevent the hubs from revolving.
For swabbing or wiping the insides of the hubs, a small rotary brush is attached to an electric motor shaft and applied to the needle hub openings 6. The side faces of the channel or strip pieces hold the needles against rotation.
The forms of the invention shown and described herein are to be considered merely as representative. It will be apparent to those skilled in the art that numerous modifications may be made therein without departing from Patented Jan. 7,1958? the spirit and scope of the invention as defined in the appended claims.
1. A device for holding hypodermic needles in a vertical position, in which the needle has a hub with an opening therein, oppositely-disposed flat side faces and a pointed tubular end extending from the hub, comprising parallel longitudinally-running opposing side members spaced to receive and bear against the oppositely-disposed flat side faces of the needle hub so as to prevent the turning of the needle when disposed therebetween, bottom restricting portions running along the lower parts of the side members adjacent the pointed tubular end of the needle to support the hubs of the needles, and providing spaces therebetween through which the pointed tubular ends or" the needles may extend, whereby the side members hold the needles against rotation when the hub openings are being cleaned with a rotary brush tool.
2. A device for holding hypodermic needles, in which the needle has a hub With an opening therein, oppositelydisposed flat side faces and a pointed tubular end extending from the hub, comprising pairs of opposingly spaced side members running continuously and having bottom restricting portions running along the lower parts of each pair of members and providing a restricted space through which the pointed tubular ends of the needles may extend While their hubs are supported upon the bottom restricting portions, the spacing of the members of each pair receiving the hubs with their fiat faces lying against the members to prevent their rotation when their openings are being 4 cleaned with a rotary brush tool, means for releasably securing together an assembly of several pairs of side members in close parallel relationship and supports secured by said releasable means to the sides of the assembly to hold the assembly and the needles above a horizontal surface.
3. A device for holding hypodermic needles, in which the needle has a hub with an opening therein, oppositelydisposed flat side faces and a pointed tubular end extending from the hub, as defined in claim 2 and a perforated member adapted to overlie the hubs of the needles and means for releasably securing said perforated member to the assembled pairs of spaced members.
