9 1955 A. s. RATHKEY INTRAVENOUS NEEDLE Filed Dec. 29, 1952 INVENTOR VFW/0195. EWWA fg B) ATTORNEYS United States Patent INTRAVENOUS NEEDLE Arthur S. Rathkey, Ogden, Utah Application December 29, 1952, Serial No. 328,333

10 Claims. (Cl. 128-221) The invention relates to needles, and more especially to needles for intravenous use.

The primary object of the invention is to provide an intravenous needle which is more satisfactory than those heretofore available. 7

Another object of the invention is to provide a needle which is simple in construction and is easy to handle and use.

A further object of the invention is to provide a needle which is readily held in position on different parts of the body.

Further objects and advantages of the invention will appear more fully from the following description, especially when taken in conjunction with the accompanying drawings which form a part thereof.

In the drawings:

Fig. 1 shows in perspective a needle embodying my invention;

Fig. 2 is a vertical cross-section through the needle;

Fig. 3 is a cross-section on the line 3-3 of Fig. 2;

Fig. 4 shows in elevation the plate which forms a part of the needle; and

Fig. 5 shows the needle in use.

The needle includes a tube 2 of relatively small crosssection having a pointed end. The other end is secured in a tube 4 of larger cross-section to which fluid can be fed through a tube 6 of transparent plastic from a conventional needle 7.

The holder for the needle is formed from a piece of malleable metal, such as malleable copper, of the shape shown in Fig. 4. This is first bent to form the handle projection 10 by bending the two parts on line 12 until they are flat against each other. Then extending wings 8 are formed by bending on lines 14 until they are at right angles to projection 10. The tubes 2, 4 are secured beneath the wings 8 as by solder 16, both tubes extending beyond the wings.

In use, the wings 8 may be readily bent, because of their malleability, to conform to the shape of the body part into which the needle is to be inserted, as shown in Fig. 5, and may be secured thereon by a single strip of adhesive 18 running transversely of the needle in front of projection 10, which slopes rearwardly from wings 8.

Projection 10 allows ready grasping of the needle for insertion and removal. Since it is arranged in the plane which includes the axis of the needle, accuracy of insertion is improved.

The resulting needle is light in weight and has a low inertia, so that it is easily held in position by adhesive tape despite fairly violent movements of the patient.

The holding power of the tape is increased by the close fitting of the wings to the body part to which the needle is attached.

By the use of a needle of small cross-section with a transparent feed tube of larger cross-section, the entrance into small veins can be readily observed since blood will soon fill the small needle and enter the transparent tubing where it can be seen. At the same time, a high capacity of flow to the needle is possible.

While I have described herein one embodiment of my invention, I wish it to be understod that I do not intend to limit myself thereby except within the scope of the claims hereto or hereinafter appended.

I claim:

1. An intravenous needle comprising a hollow tube having a pointed end, a second tube of an inside diameter equal to the outside diameter of the first tube secured on the end opposite the pointed end, a plate-like member secured on said tubes intermediate the length thereof, both tubes extending beyond the member, and an upward handle projection from said member in a plane which includes the axes of the tubes.

2. A needle as claimed in claim 1 in which said member is of malleable metal.

3. An intravenous needle comprising a hollow tube having a pointed end, a second tube of an inside diameter equal to the outside diameter of the first tube secured on the end opposite the pointed end, and a piece of metal comprising a central section bent back upon itself to form a handle part and bent to form wings extending from the lower edge of the handle part, and means securing said tubes to said piece with the axes of the tubes in the plane of the handle part.

4. A needle as claimed in claim 3 in which said piece is of malleable metal.

5. An intravenous needle comprising a hollow tube having a pointed end, and a piece of metal comprising a central section bent back upon itself to form a handle part and bent to form wings extending from the lower edge of the handle part, and means securing said tube to said piece with the axis of the tube in the plane of the handle part.

6. A needle as claimed in claim 5 in Which said piece is of malleable metal.

7. In a device as claimed in claim 6, said handle part being inclined away from the pointed end of the tube.

8. In a device as claimed in claim 5, said handle part being inclined away from the pointed end of the tube.

9. A needle as claimed in claim 1 in which said platelike member and handle projection are formed of a piece of metal comprising a central section bent back upon itself to form the handle projection and wings extending from the lower part of the handle projection to form the plate-like member.

10. A needle as claimed in claim 9 in which said piece is of malleable metal.
