This invention relates to a guard or holder for (Cl. 206-43) hypodermic needles. Figure 8 is a perspective view of a preferred form of my invention. One of the objects of this invention is to pro vide a guard for a hypodermic needle which will Referring now in greater detail to the drawing and to Figures 1, 2, 3, 4, and 5 in particular, the 5 prevent injury to. the canula or point during shipping, handling, sterilizing and the like. Another object of this invention is the provision of a hypodermic needle guard which will act as a gauge to indicate the length of the canula of the 10 hypodermic needle. Another object of this invention is to provide a hypodermic needle guard which may be easily attached to and detached from the hypodermic numeral l0 denotes the hub of a conventional Ll hypodermic needle having a tapered internal bore H and a circumferential groove l2. A sharpened canula or needle I3 is affixed in one end of hub l0‘ and communicates with the ta~ pered bore 1 l. A wire or stylet l4 passes through i 10 the bore of the canula to protect it when the needle is not in use. The wire M is provided with a handle plug I5 attached to one end thereof, needle even with wet or gloved hands. said .plug having a tapered portion l5a adapted A further object of this invention is to provide to fit into and to close the tapered bore H, and in a hypodermic needle guard of this type means adapted to be used as a handle for inserting, re for facilitating the removal and subsequent han moving and handling the wire M.

Two tabs or ?ngers l8 are formed integrally The means by which I accomplish the above with the base plate I6 and are turned upwardly and other objects which will later be apparent from substantially the center of the two longest :37, are best understood by referring to the following edges of the base plate opposite each other, and description taken in connection with the accom the upper ends I9 of. said tabs are bent slightly panying drawing, in which toward each other thus adapting them to grip Figure 1 is a side elevation of a hypodermic the hub 10 of the hypodermic needle in the cir needle guard constructed according to my inven cumferential groove 12, the hub lying along the All) tion, shown attached to a hypodermic needle of upper surface of the base plate It. the usual type, having a stylet formed with a The base plate It has joined thereto, by means solid head contained therein, of the integrally formed connecting portion 20 Figure 2 is an end view of the same looking which forms an obtuse angle with the base plate from the canula end of the needle, I6, a trough or groove portion 2|, formed inte l Figure 3 is a vertical cross section of same taken along its longitudinal medial axis, Figure 4 is an end view of the same taken from grally with the base plate 16, and connecting por- » tion at, and having a V-shaped cross section as shown clearly in Figure 2. a the end opposite to that of Figure 2, Figure 5 is a plan view of the same, The longitudinal axis of the trough portion 2| is parallel to the surface of the base plate is and Figure 6 is a side elevation of an optional form of my invention shown attached to an ordinary hypodermic needle containing a wire loop for pro to the longitudinal axis thereof and is so spaced ; therefrom that when a conventional hypodermic needle is so placed in the device that the hub 10 rests on base plate IS with tabs I8 and the bent tecting the bore of the canula, Figure 7 is an end view of the same taken from 55 the end opposite the canula, and "' end portions I9 thereof engaging and gripping the hub NJ at the circumferential groove l2, the 2 2,110,123 canula l3 will lie wholly within said trough por tion, thus protecting canula l3 from contact with external objects. The two inner surfaces of the trough portion 2| may, if desired, be inscribed said base plate portion from the edges thereof, an upwardly and outwardly slanting connecting with suitable indicia such as maker’s or owner’s names, trademarks etc., or may have suitable ation of said connecting portion and lying parallel to said base plate portion. scales laid off thereupon for indicating the length of the canula of the needle, such as for example those shown in Figure 5, where one face carries 3.'A hypodermic needle guard of narrow rec tangular form comprising a base plate, integrally 10 an English and the other face a metric scale. portion forming an extension of said base plate portion, and a trough portion forming a continu formed needle engaging tabs projecting at right angles to said base plate from opposite edges thereof, an end tab projecting at right angles to [said base plate from one end thereof, and an Figures 6 and 7 show an alternate or optional = " integrally formed trough portion forming an ex form of my invention.

A hypodermic needle guard of one-piece this form of my invention the upwardly turned end Ila is narrowed toward its base as shown in " construction comprising a base plate portion, a Figure '7. This upwardly turned end lid is made plurality of tabs projecting at right angles to said v20 small enough to pass through the loop Ma and base plate portion from the edges thereof, an 20 may thus be used as a‘ hook or handle to facilitate upwardly and outwardly slanting connecting por removing the looped wire from the needle and tion forming an extension of said base plate por Similarly the upper and lower face of base plate I6 may be inscribed or stamped as. desired. in subsequently handling or reinserting said wire, it being understood that the needle is removed 25 from the guard during this operation. The nar tion, and a trough portion forming a continuation of said connecting'portion and lying parallel to said base plate portion, said trough portion being rowed neck portion of the upturned end Ha is for the purpose of preventing the wire loop Illa from accidentally becoming disengaged there from. It is, of course, understood that either of 30 the upturned tabs I8 may be used as above de inscribed with mensuration indicia on its inner scribedto remove and handle the looped wire. The operation of inserting the needle into the device consists in placing the hub in position so from opposite edges of said base plate at sub stantially right angles thereto, and having their free ends bent slightly, toward each other and that the ends IQ of tabs l8 lie in groove l2 and along vthe trough portion 2|. adapted to engage the hub of a conventional hy podermic needle, an integral end tab projecting Slight pressure of the hub will then spring the ‘tabs l8 apart su?iciently to allow the hub 10 to upwardly from one end of said base plate sub pass between them until it lies upon base plate H6. The inherent elasticity or springiness of tabs l8 will cause them to grip the hub and retain it in this position. To remove, the hub is gripped be tween thumb and fore?nger and pulled upward, upwardly slanting connecting portion positioned at the opposite end of said base plate, an integral trough member of substantially a V-shaped cross 40 section connected by said connecting member to said base plate, said trough member spaced above meanwhile holdingrthe guard in the other hand. The tabs I8 spring apart and allow the hub to member carrying suitable mensuration scales on 35 the canula lies 45 pass out between them. ' - While I have here shown and described cer tain preferred forms of my invention it will be obvious to those ‘skilled in the art that certain changes may be made in the details of construc tion, and I therefore do not wish to be limited by the actual construction shown except insofar as I am limited by the scope of the appended claims. Having described my invention, what I claim 55 as new and desire to secure by Letters Patent is: 1. A hypodermic needle guard of narrow rec tangular form comprising a base plate, integrally formed needle engaging tabs projecting at right angles to said base plate from opposite edges 60 thereof, and end tab projecting at right angles to said base plate from one end thereof, and an in tegrally formed trough portion forming an ex tension of said base plate spaced from and paral lel thereto. 2. A hypodermic needle guard of one-piece 65 construction comprising a base plate portion, a plurality of tabs projecting at right angles to surface. 5.
