HYPODERMIC sYnINGn Specication of Letters Patent.
Application tiled July 14, 1911.
To all whom it may conce/m Be it known that I, JAMES T. GREELEY, a citizen of the United States, and ,a resident of Nashua.,in the county of Hillsboro and State of New Hampshire, have invented certain new and useful Improvements in Hypodermic Syringes, of which the following is a specification.
This invention relates to a hypodermic syringe 1of the general character described in my a plication for Letters Patent of the United tates filed March 25, 1911, Serial No. 616,934, said syringe comprisingl a collapsible capsule charged with liquid and having a breast at one end and a contracted neck integral with the breast, said capsule, breast and neck bein composed of ductile material, and a hypo ermic needle inserted in the neck and having a practically nonrenewable connection therewith caused by the compression of the neck around the needle, the capsule being hermetically closed so that there is no outlet for the charge of liquid excepting through the lumen of the needle.
The objects attained by the said syringe are asepsis and celerity, the needle permanently attached to the charged capsule being ready for immediate use and being incapable' ofl a second use after the charge of liquid in the capsule has been ejected.
The present invention consists in the improvements hereinafter described and .claimed in ahypodermic syringe character` izedas above stated.
Of the accompanying drawings which form a part of this specification,-Figure l1 represents a longitudinal section ofla hypodermic syringe embodying my invention, a part of the capsule` being.r shown in eleva- Fig. 1 showing the syringe inclosed in a holder and a stylet inserted. .in the lumen of the needle as a plug; Fig. 3 represents a longitudinal section showing a portion of the holder and the stylet removed from the needle; Fig. 4 is a perspective view of the syringe, a portion of the capsule heilig broken oit. i
Similar reference characters .indicate the same or similar parts in-all the figures.
In thedrawings,-12 represents a capsule, and 13 a hypodermic needle attached thereto. Thecapsule has no opening, except that provided by the lumen of the needle, and 1s charged with a liquid solution through one of its ends, the said .end being closed and sealed after the insertion of the charge, so that the capsule is non-rellable.
The capsule is preferably a tube composed of a ,ductile metal or alloy, such as that usually employed for collapsible tubes containing glue, paint, etc., the wall of the tube being relatively thin so that it may be collapsed and flattened by external pressure between the thumb and fingers. One end of the tubel is contracted to form a breast 14, the .central portion of which is extended to form a tubular neck 15, integral with the breast-and of much smaller diameter than the4 main portion of the tube, the internal diameter of the neck being practically the same as the external diameter of the base portion of the needle. The base or inner end portion of the vneedle may be of any suitable formation, whereby it is adapted to be interlocked with the material of the neck 15 to prevent ,endwise movement of the needle relatively to the neck.
In Figs. 1 and.2, I- show the external surface of theportion of the needle which enters the neck, roughened or corrugated, at 16. When the needle is inserted 1n the neck, the latter is compressed by a suitable -tool to force port-ions of its material into engagement'with the prepared surface of the needle, thus establishing a suitable nonrenewable union between the needle and the neck. If desired, the non-renewable union may be a solder joint, applied in any suitable way.
17 represents a stylet which 1s adapted to enter the lumen of the needle and constitute a plug to prevent leakage of liquid through the needle. The lstylet is composed of a single length of Wire, formed to somewhat closely t the lumen, the upper por- ,tion of the wire being formed into a series of coils, or otherwise bent to form an anchor 18.
The inner end of theneck 15 is provided with a cavity 19, the bottom of which surrounds the inner end of the needle 13. Before the capsule is charged, the stylet 17 is inserted in the lumen of the needle, the
inner end of the stylet projecting through ,the lcavity 19. A filling 2O is then inserted in the cavity 19, said filling being of any suitable material. The filling 20 and the protective body 23 hereinafter described may be of any suitable material, paraiin belng preferred, thismaterial being adapted to liquefy at a' temperature lower than the melting point of the material of the capsule, so that vit may be sterilized by heat without injury to the capsule, and is adapted to solidify by cooling when in pl'ace. A material such as collodion, adapted to solidify by evaporation, may be employed if desired. rlhe said filling prevents contact of the liquid `contents of the capsule with the needle, so that rusting and contamination of the needle is prevented. The said filling is inserted in the cavity 19 before the capsule ischargedland sealed. The filling 20 forms a liquid-tight packing around the stylet so that there is no possibility of leak-- age of the liquid through or into the crevice surrounding the stylet. The filling 20 forms a hermetic seal around the inner end portion of the stylet which not only prevents leakage of liquid around the styletl but also prevents access of dust, moisture and infection of any sort to the contents of the capsule.
21 represents a non-collapsible grip member of improved construction differing from that shown in the above-mentioned applicat-ion. The grip member 21 is a rigid ring preferably of metal, the opening of which is formed to closely embrace the periphery of the neck 15, the neck 'being crowded tightly into the ring so that it is held firmly therein by Ifrictional contact with the inner margin of the ring. The periphery of the ring is of about the same diameter as`the capsule, so that it is adapted to support the pressure of the thumb and finger of the hand in which the syringe is held, thus preventing such pressure from collapsing the capsule when pressure is exerted to force the needle into the skin. The construction of the grip member heretofore employed was such that a solder connection between it and the neck was required. The annular grip member here shown requires no solder connection and furishesa continuous supporting surface entirely surrounding the neck 15.
22 represents a holder which is preferably a glass tube closed at one end and open at the opposite end, the tube being adapted t-o receive the capsule and needle as shown byy 23 represents a body of protective material, which is preferably of the same material as the filling 20,and occupies the closed end of the holder and adheres thereto. The point, and preferably the greater part of the projecting portion of the needle, together with 'the anchor 18 of the stylet 17, are embedded in the body 2 3 preferably while the latter is in a semifluid condition, the needle containing Ithe stylet being inserted in the holder before the material l -ternal surfaces of the needle, but also prevents lateral movement of the needle in the holder, the flattened end 12a of the capsule i c extending across the holder and preventing lateral movement of the capsule therein. The open end of the holder 22 may be closed by a removable cap 24 of elastic rubber, paraiiin paper, etc. y
When the needle is to be used, the cap 24 is removed and the capsule and needle vare Withdrawn from the holder, the body 23 of protective material retaining the stylet in the holder, asindicated by Fig. 3. The withdrawal of the stylet from the filling 20 leaves an opening in said filling, said opening being a continuation of the lumen of the needle. The material of the filling 20 and body 23 should be thoroughly sterilized so that no sterilization of the needle is required after its withdrawal from s aid body.
rIheform ofthe capsule is such that the flattening or collapsing of the entire capsule will expel practically the entire charge of liquid through the needle, the collapsing pressure being applied by the thumb and fingers of the hand in which the capsule is held'. f I claim l 1. A hypodermic syringe composed of a collapsible capsule charged with liquid and having a breast at one end and a neck integral with said breast, said capsule, breast and neck being composed of ductile material, a hypodermic needle inserted in said neck and secured therein by the compression of the material of the neck around the needle, the neck being provided at its inner end with a cavity, the bott-om of which surrounds the inner end of the needle, a stylet inserted as a plug in the lumen of the needle, and a liquid-proof filling occupying said cavity and interposed between the needle and the contents-of the capsule, said filling constituting ahermetic seal around the stylet.
2. A hypodermic. syringe composed of a collapsible capsule charged with liquid and having a breast at one end and a nec-k integral with said breast, said capsule, breast and neck `being composed 4of ductile material, .a hypodermic needle inserted in said neck and secured thereto by the compression of the material of theneck around the fneedle, and a rigid ring embracing and closely fitting said neck and constituting a continuous non-collapsible grip member.
3. In combination, a hypodermic syringe composed of'a collapsible capsule charged with 1i uid and having an integral neck at one en a hypodermic needle inserted in saidneck and having a permanent connec tion therewith, a stylet inserted in said needle as a plug for the lumen thereof, said stylet having an anchor at its outer end, a holder inclosing the capsule and needle and having a closed end and an open end, and a body of protective material occupying the closed end of the holder and adherlng thereto, the point of the needle and the anchor of .the stylet being embedded in said body,
whereby rusting of the needle point is prevented and the Withdrawal of the' capsule and needle from the holder causes the separation of the needle from the stylet, the latter remaining anchored in said body.
4. In combination, a hypodermic syringe composed of a collapsible capsule charged with liquid, a hypodermic needle having a permanent connection with the capsule, a holder inclosing the capsule and needle and having a closed end and an open end, and a body of protective material occupyin the closed end of the holder and adheringt ereto, the oint ofthe needle being embedded in said Body.
In testimony whereof I have affixed my signature, in presence of two witnesses.
