INTRADERMIC SYRINGE.

Application filed January 14, 1915.
To all whom it may concern:
Be it known that I, WI LIAM H. FURNEss, a citizen of the United States, residing in National Park, Gloucester county, State of New Jersey, have invented certain Improvements in Intradermic Syringes, of which the following is a specification.
One object of my invention is to provide a relatively simple and conveniently operated form of syringe particularly designed for the administration of vaccine, serum, etc., between the layers of the skin, though obviously it may be employed for other purposes, it being especially desired that the device while being of such a nature as to allow of highly accurate use, shall likewise be simple in construction and convenient to operate.
Another object of the invention is to provide a syringe having the above characteristics which may be easily maintained or rendered aseptic and v in whlch relatively small doses of serum or the like may be ad ministered in exactly the quantities desired.
A further object of the invention is to provide a syringe particularly designed for'intradermic use, which shall include a needle of novel construction designed to cooperate in a novel manner with a suitable barrel or container, the invention also contemplating a novel form of package or holder for the serum or other substance required in making intradermic injections.
These objects and other advantageous ends ll secure as hereinafter set forth, reference being had to; the accompanying drawings, inwhich;
Figures 1 and 2 are side elevations of the syringe barrel, which also constitutes the container or package for serum or the like, and of the needle constituting my invention respectively, and Figs. 3 and -t1vely vertical longitudinal sections on a greatly enlarged scale,
of the parts shown in Figs. 1 and 2.
In the above drawings 1 represents a relatively heavy or comparatively non-fragile tube of glass permanently closed at one end and open at the other, which while having a bore of relatively small diameter, does not require said'bore to be accurately uniform The vaccine, serum Specification of Letters Patent.
Patented Met. 19, 1915. Serial No. 2,198.
cover 3 preferably ofrubber which may if desired be sealed in place as shown at 12 by any suitable material, though this is not necessary in most cases since the cap itself if properly proportioned will make an air tight seal with the glass.
he needle for use with the above described barrel consists of an elongated tube 4 of metal or other material having a point portion 8, an intradermic portion 9 and a plunger portion 10. Of these, the plunger portion has by far'the greatest length and is provided with any desired number of transverse marks or graduations 5, 5 5", 5, etc., being so made that a section between any two adjacent graduations has a definite known volume. The diameter of this plunger portion 10, while it may be approximately the same the cavity 2, is usuallyof some other diameter less than this, and while its end distant from the portion 9 is preferably more or less sharp as indicated at 6, it may be made blunt if desired. The intradermic portion 9 of the needle ,has any suitable length, for example one-fourth of an inch,
and is of a diameter considerably less than that-of the plunger portion, finally terminating at its extremity in a more or less elongated and relatively sharp the channel or passage 7 of said needle opens. A suitable handle for the needle is provided by a strip 11 projectingat nght angles from the plunger portion adjacent the intradermic portion 9 and attached thereto in any desired manner. Obvlously this handle may be of other forms without departing from my invention.
Under conditions of use the needle, which is kept in a sterile envelop or wrapping until required, is grasped by the handle 11 and its end 6 is forced through the rubber cap 3 into the cavity of the container or package '1. As 1t is moved into thelatter the serum or other substance by the plunger the channel 7 of the opening as the interior diameter. of
point 8 in which Y with the top surface 'of the cap 3, thus indithe eontalner 1 conditions the cap or closureB of eating that an amount of material has been administeredexactly equal in volume to the a I predetermined-volume of the plunger portion between the graduations 5 and 5 or 5 as the case may be. Afterthe administration of one 'dose the container and needle may be discarded, or if desired may be used for the administrationof other doses by forcing the plunger portion 10 farther into and causing the discharge of additional amounts of material through the pointed portion 8. 'Under the above noted the tube or package 1 effectually serves as a stufling box for the plunger'portion of the needle which'is held and guided by the handle 11. There is thus no danger of contaminating the material administered or of infecting the held; thereto wound made by the needle point.
It is to be understood'that the handle or holding portion 11 is not necessarily permanently fixed to the needle 4 but may be by friction andit may be apfarther onto the plunger portion 10 of the of the graduations 5 or 5* is brought plied when the needle is to be used. For this purpose the end of the plunger portion 10 adjacent the portion 9 may be slightly tapered as shown, either with .or without splitting the tubular portion 13. Under conditions of use I have found the fiat radially extending form of this holding tab or handle 11 an important feature as it permits of the delicate manipulation of the needle necessary in inserting it intradermically, although any shape of handle permanently or removably attached adjacent the intradermic portion 9 may be employed without departing from my invention. I claim be administered. within the tube; a puncturable cap sealing the open end of the tube; with a needle having an elongated plunger portion of substantially uniform diameter and having a volume substantially e ual to that of the desired dose of liquid to e administered, for displacing the liquid in the tube when it is forced through the cap into the same. p In testimony name to this specification, two subscribing witnesses.
