HYPODERMIG NEEDLE. I No. 268,996. Patented'Deo. 12, 1882.
WITNESSES INVENTOR ZWM. XZMEW/ [Q1 ATTORNEYS UNITED STATES PATENT @FHCE;
ALEXANDER W. BRINKERHOFF, OF UPPER SAXDUSKY, OHIO.
-'HYPODERMlC NEEDLE.
SPEOIFIGATIONforming part of Letters Patent No. 268,996, dated December 12, 1882,
Application filed July 31, 1882. (No model.)
To all whom it may concern Be it known that I, ALEXANDER W. BRINK- ERHOFF, acitizen of the United States, and a resident of Upper Sandusky, in the county of Wyandot and State of Ohio, have'invented a new and valuable Improvement in Hypodermic Needles; and Ido hereby declarethat the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, makinga part of this specification, and to the letters and figures of reference marked thereon. Figure l of the drawings is a representation of this invention in a perspective view. Fig. 2 is asection taken lengthwise of the instrument. Figs. 3 aud t are details showing side views of the different pieces. Fig. 5 is a modification of the invention.
Thisinvention has relation to hypodermic injector-needles; and it consists in providing the tubular needle with an adjustable sleeveguard designed to protect the point of the needle, to gage the depth to which it ma be inserted, and to prevent the escape of the aid from the skin after injection, all as hereinafter set forth.
In the accompanying drawings I have illustrated this invention in simple and practical form.
The letter a designates the tubular needle.
having the pointed end I), and seated in the stem 0 of the instrument, which extends from thechamberedportion or receptaclecl, in which the fluid is placed which is to be injected. The stem 0 is threaded on its outer surface to engage a sleeve-guard, c, which is interiorly threaded, and is formed witha flattened rounded end, g, in the center of which is made a perforation, 70, through which the tubular needle passes.
It is apparent that instead of using the screw principle for effecting the adjustment of the sleeve-guard a similar end may be attained by employing a friction-spring, a fine ratchet and spring-pawl, or a clamping device; but the screw adjustment is very much preferable, because of its certainty and'the ease with which it is operated.
By turning the sleeve guard itcan be moved forward so that its rounded end g will be beyond the point I) of the needle, which can therefore be entirely iuclosed and protected when not in use. The sleeve-guard can be moved back as far as may be necessary to allow any required extent of the tubular needle to project beyond its rounded or gage end. 9, according to the depth to which the needle is designed to be inserted under the skin. This is a very important advantage, securing certainty and uniformity in the application, even in the hands of a nurse, when the gage has been set by the physician.
After the injection of the morphine solution or other liquid the instrument can be turned so as to retract the needle,leaving the rounded end gpressed upon the punctured skin, where the openingg by turning the threaded stem 0 in its sleeve 0 until the point is extended the required distance, the sleeve 6 acting asa stop to gage the depth to which the needle is to penetrate the skin. The liquid, which has been previously placed in the chamber (1,18 then forced by the piston commonly employed in this class of needles into the orifice made by the needle, and the screw 6 is then' reversely turned to withdraw the needle-point within the sleeve 0, the rounded point g of the latter being held against the skin to prevent the fluid from escaping from the orifice until absorption takes place. Ahypodermiic syringe having the needle detachable from the pistonrod, so as to enable the same to be reversed and inserted in the hollow rod when the in strument is not in use, and covered bya short cap applied to the syringe-barrel, has been used prior to my invention. A protecting cover or shield for the needle is not broadly new, and aregulating-screw to stop the action of the syringe at the required spotis also old.
I do not therefore claim said cmstruotions herein. specified.
Having described this invention, what I In testimony that I claim the above I have claim, and desire to secure by Letters Patent, hereunto subscribed my name in the presence which the needle projects, substantially as to .is of two witnesses.
In a hypodermic injector, the threaded stem ALEXANDER W. BRINKERIIOFF. c of the tubular needle, and the interiorlyitnesses: threaded sleeve'guard 0, engaging said stem, M. H. BRINKERHOFF,
