HYPODERMIC SYRINGE HOLDER AND GUIDE Arthur L. Collins, Troy, N. Y.

Application February 2, 1948, Serial No. 5,828

The present invention relates to new and useful improvements in holders for hypodermic syringes designed particularly for use in the self administration of hypodermic injections and including the provision of guide means slidably supporting the syringe in a steady position along the line of penetration and at the proper angle of penetration without aid from the operator.

An important object of this invention is to provide a syringe holder which relieves the operator of all manual support of the syringe and which enables the plunger to be pushed for the insertion of the needle without danger of the needle moving in any direction.

A further object is to provide a holder of this character wherein the needle is guided at a proper angle and wherein the needle is regulated to a proper depth of penetration and which further insures the removal of the needle along the line of penetration.

A still further object is to provide a device of this character of simple and practical construction, which is eflicient and reliable in use, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view showing the syringe holder supported in position on a person; Figure 2 is a longitudinal sectional view, and

Figure 3 is a transverse sectional view taken substantially on a line 33 of Figure 2.

Referring now to the drawing in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, thenumeral 5 designates a base plate curved to conformably seat on the arm, leg or other part of apersons body 6 and held in position by a strap I. The front end of thebase plate 5 is'forked as shown at 8 to prevent covering of the parts of the body in the region of the area to be treated.

A pair of guide rods 9 are supported in spaced parallel relation with respect to each other above thebase plate 5 in a forwardly inclined position by legs H1 at the front ends of the rods suitably secured to theforked ends 8 of the base plate.

A slide II in the form of a rigid plate has its side edges rolled to provide sleeves l2 which are slidable on the rods 9. Pairs of opposed tongues l3 are struck upwardly from the plate II at the 8 Claims. (Cl. 128215) front and rear portions thereof to provide clips for holding the barrel of a hypodermic syringe M in a longitudinally extended position on top of the slide and with theneedle 15 of the syringe projecting forwardly thereof.

In the operation of the device, thebase plate 5 is strapped to the arm or leg of a person and the slide l l with the syringe I4 firmly held thereon is moved forwardly to cause the insertion of the needle in the part of the body immediately forwardly of the base plate. The forked front end of thebase plate 5 enables the flesh of the person to be treated to be pinched or raised in the usual manner of giving :a hypodermic inieotion.

The legs ill of the front ends of the guide bars 9 limit the forward sliding movement of the slide H to regulate the depth of penetration of the needle l5 and the syringe is thus firmly held while the plunger of the syringe is pushed forwardly to accomplish the injecting action and without danger of movement of the needle.

The needle is withdrawn by a rearward sliding movement of the slide H and the guide rods 9 hold the needle in the line of penetration during its withdrawing movement.

In View of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended b the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention what is claimed as new is:

1. A hypodermic syringe holder comprising a body attached member, a reciprocating syringe supporting slide carried by the member for traveling thereon toward and away from a body to be ejected by the syringe, and means carried by the slide holding a syringe thereon for movement with the slide into and out of injecting position.

2. A hypodermic syringe holder comprising a body attached member, and a reciprocating syringe supporting carriage slidably mounted on the member and rigidly supporting a syringe for guiding the syringe into and out of injecting position.

3. A hypodermic syringe holder comprising a body attached member, and a reciprocating syringe supporting carriage slidably mounted on the member and rigidl supporting a syringe for guiding the syringe in a rectilinear path into and out of injecting position.

4. A hypodermic syringe holder comprising a body attached member, guide means supported by the member, and a slide mounted for reciprocating movement on said guide means and rigidly supporting a syringe for movement with the slide into and out of injecting position.

5. A hypodermic syringe holder comprising a body attached member, guide means supported by the member, and a slide mounted for reciprocating movement on said guide means and rigidly supporting a syringe for movement with the slide into and out of injecting position, said guide means being inclined toward the point of penetration of the needle of the syringe.

6. A hypodermic syringe holder comprising a body attached member, guide means supported by the member, and a slide mounted on said guide means and rigidly supporting a syringe for move,- ment with the slide into and out of injecting position, said guide means comprising a, pair of guide rods inclined toward the point of penetration of the needle of the syringe.

'7. A hypodermic syringe holder comprising a 4 body attached member, guide means supported by the member, and a slide mounted on said guide means and rigidly supporting a syringe for movement with the slide into and out of injecting position, said guide means comprising a, pair of guide rods inclined toward the point of penetration of the needle of the syringe, and said slide comprising a rigid plate having sleeves at its side edges slidably carried by the rods.

8. A hypodermic syringe holder comprising a body attached member, a pair of guide rods supported in an inclined position by the member, a. syringe holding plate slidably mounted on the rods, and opposed pairs of tongues projecting from the plate in rigid gripping engagement with a syringe.
