HYPODERMIC NEEDLE.

UNITED STATES PATENT OFFICE.

FRANK RUSSELL HART, OF SANTA CRUZ, CALIFORNIA.

HYPODERMIC NEEDLE.

To all whom it may concern Be it known that I, FRANK RUssnLL HART, a citizen of the United States, residing" at Santa Cruz, in the county of Santa Cruz and State of California, have invented new and useful Improvements in Hypodermic Needles, of which the following is a speciiication.

My invention relates to an improved hypodermic needle; the object of the invention is to provide a hypodermic needle with a clear glass passageway, which passageway leads from the needle to the end of the syringe and is connected to the syringe either by a male or female slip or other joint. This glass passageway permits the operator when giving a hypodermic injection to clearly determine if the end of the needle is under the skin, in the muscle or in a vein.

In the accompanying drawings Figure 1 is a longitudinal section of the hypodermic needle; 2 indicates a platinum or other metal needle; 3 is a glass tube; 4 is a female sleeve; 5 indicates the point where the platinum needle and the glass tube 3 are welded or joined together; 6 is the point where the metal sleeve 4: connects with the glass tube 3; 7 is a passageway in the needle which communicates with 8, the passageway in the glass tube 3; 9 is the passageway in the sleeve into which the end of a syringe may be fitted. Fig. 2 is a hypodermic needle of the same construction as Fig. 1 with the exception that the glass tube 3 ends at 4 and forms at this point a male connection with the syringe. Fig. 3 is a hypodermic needle of the same construction as Fig. 1 with this exception :-The glass tube 3 has no metal Specification of Letters Patent.

Application filed April 22, 1913.

Patented June 16, 1914.

Serial No. 762,761.

sleeve, 4: represents the female sleeve which is made from glass and is a continuation of the glass tube 3.

In using the needle, the needle is slipped over the end of a syringe, the syringe is filled with solution and all of the air expelled, and the point of the needle is inserted into the skin; if an intravenous injecti on is to be given and the needle has entered the vein, upon drawing back on the plunger of the syringe, blood will appear in the clear tube 8, which clearly shows without getting the blood back into the body of the syringe that the vein has been punctured. In giving a sub-cutaneous or inter-muscular injection, when it is desired to know if you are in the muscle or under the skin and have not entered a vein, by drawing back on the plunger of the syringe, if no blood appears in the glass tube 3, it will be clearly seen that the point of the needle is under the skin or in the muscle and not in the vein.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

A hypodermic needle comprising a transparent capillary tube to one end of which is rigidly, inseparably and hermetically joined a hollow hypodermic needle, the opposite end of the tube being adapted for attachment to a syringe.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

FRANK RUSSELL HART.
