Sept. 16, 1941 B. L. TAYLOR POCKET SYRINGE Filed May 21, 1940 ll-II mm INVENTOR BARNEY L. TAYLOR BY I Q ATTORNE? Patented Sept.'16, 1941 UNITED STATES PATENT OFFICE (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) 2 Claims.
This invention relates to a pocket syringe, and has for an object to provide an improved pocket syringe of the type generally shown in U. S. Patents 991,022 and 1,490,966, but having advantages over the devices of these patents in economy of construction and simplicity of use.
A further object of this invention is to provide an inexpensive pocket syringe which can be easily carried and is of the type that it may be carried in the pocket when the syringe is already filled with the antiseptic liquid without danger of leakage, irrespective of the position it may assume in the pocket, and furthermore, may easily have a new antiseptic solution made therein by dropping a soluble capsule containing a concentrated antiseptic therein and then filling the syringe with water so as to dissolve the capsule and make the syringe ready for use, the antiseptic capsule being of a type that may be easily carried in the pocket in a small pill box.
A further object of this invention is to thus provide a pocket syringe having a flattened nozzle, small in size yet capable of providing a number of medicated injections whenever desired. Thus when used as a nostril, ear or meatus syringe and it is necessary in the treatment that a number of applications be applied to the nostril, ear, meatus or other orifices of the body, it is possible for the patient to carry a pill box of antiseptic capsules and the pocket syringe of this invention, whereby he may easily carry a days or even a week's supply in his pocket, available for use whenever he can get access'to water, such as at any drinking fountain, or the like.
With the foregoing and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter described and illustrated in the drawing, in which,
Fig. 1 is an elevational view of the pocket syringe of this invention;
Fig. 2 is an end elevation of Fig. 1;
Fig. 3 is a sectional view on line 33 of Fig. 1;
Fig. 4 is an exploded view of several parts of the syringe; and
Fig. 5 is an enlarged top plan view of Fig. 1.
There is shown at IU the pocket syringe of this invention. This syringe I includes a bulb H which, as shown in Figs. 1 and 3, is provided with flattened sides l2 and has a thickened tip I3 through which extends an opening M of sufficient diameter for medicated or antiseptic soluble capsule l to pass therethrough into the hollow body I6 of the bulb The bulb II and its thickened tip l3 are made of soft, flexible rubber, the thickened tip l3 having an external diameter slightly less than the thickness of the bulb between its flattened side walls l2. A cap made of hard rubber or other suitable plastic material, is provided with a skirt |8 having an outwardly flared edge 20, the internal diameter of the skirt l8 being just slightly less than the external diameter of the thickened tip l3 of bulb The cap I! terminates in a somewhat flattened conical nozzle 2| leading to a centrally extending counterbored aperture 22. small bore 23 of the aperture 22 at the outer point of the cap I1 is somewhat oval shaped and the large bore extends from a point about halfway, more or less, between the outer tip of the conical nozzle 2| and its inner wall 25.
An aluminum sealing pin 26 has a small cylindrical end 21 of a diameter slightly larger than the internal diameter of the bulb aperture l4, so that while the cap I! is removed from the bulb tip I3 the pin 26 may have its thin cylindrical end 21 inserted in the tip aperture I4 up to the pin shoulder 28 to thus seal the bulb II and be held in sealing position by the resiliency of the bulb tip l3. The larger or handle end 30 of the aluminum. pin 26 is of such a diameter that it may fit easily within the counterbore opening 24 in cap I"! so that the cap I! may be placed thereover and be retained in assembled position for carrying purposes by the resiliency of the bulb tip l3.
In operation, as thus described, the syringe ||l may be carried in a garment pocket or handbag, either empty or already filled with the liquid 3|. To make it ready for use, the cap I! is temporarily removed, allowing the sealing pin 26 to be withdrawn from the bulb tip l3, and then the nozzle cap H is replaced, as shown in Figs. 1 and 2, making the syringe ready for immediate use, the nozzle tip 2| being placed in the nostril, the ear, meatus, or other body orifice, and the liquid inserted therein by squeezing the sides of the bulb II, it being noted that the flattened shape of the nozzle tip 2| and of the opening 23 make it more eflicient in use.
If the syringe has just been emptied, it may be refilled by dropping another antiseptic or medicated cylinder I5 through the bulb tip aperture l4 into the hollow portion l6 of the bulb N. Then by squeezing the sides of bulb H and inserting the bulb tip I3 into a suitable supply of water, the bulb I6 may be filled with water to dissolve medicated cylinder I5, making the syringe ready for use within a few minutes; or if the user wishes to carry the filled syringe Theing from the nature of this invention, within the scope of what is hereinafter claimed.
The invention described herein may be manu- I factured and/or. used by or for the Government of the United States of America for governmental purposes without the payment of any royal-'1 ties thereon or therefor. 7
Having thus set forth and disclosed the na ture of this invention, what is claimed is:
1. A pocket syringe comprising a bulbjbody and I a bulb tip' of compressible material, said bulb tip having a nozzle aperture extending therethr ough, an apertured'nozzle cap and an extending skir't on said nozzle cap, said nozzle cap and skirt being of relatively non-compressible material, the interna'l Eopening -witliin said no'zzle cap skirt being slightly less than the outside of' th'e compressible bulb tip, whereby to removably hold said nozzle in operative position on said bulb tip, and a sealing pin having a small sealing end of a diameter to fit snugly Within said bulb tip, the aperture through said nozzlecap being counterbored and having its small end at the nozzle tip and the large end within said cap to fit easily over a large handle end of said sealing pm.
i 2. A pocket syringe comprising a bulb body and a bulb tip of compressible material, said bulb i tip having a nozzle aperture extending there- 'through, an apertured nozzle cap comprising a conical nozzle and an extending hollow flared skirt on. said nozzle cap, said nozzle cap being of relatively non-compressible material, the internal opening within said nozzle cap skirt being slightly less than the outside of the compressible bulb tip, whereby to removably hold said nozzle inoperative position on said bulb tip, a sealing pin having a small sealing end of a diameter to fitsnugly within said bulb tip, the'aperture through said nozzle cap being counterbored and having its small end at the nozzle tip and the large end Within said cap to fit easily over the large end of said-sealing pin.
