DECEPTIONELEMENT FORHYPODERMIC SYRINGES July 29, 1958 Filed Feb. 5, 19541 INVENTOR DHNIEL. GHBRIEL ATTORNEY United States Patent DECEPTION ELEMENT FOR HYPODERMIC SYRINGES Daniel Gabriel, Bonny Blue, Va. Application February 5, 1954, Serial No. 408,358

8 Claims. (CL, 128-215) This invention relates to hypodermic syringes for use in performing injections into a patient. More particularly, the invention deals with what I term a deception element for devices of this type and kind, that is to say, an element which covers and envelopes the needle of the syringe and provides a relatively large body therearound, so as to relieve the patient of the optical or mental fear of having a needle pierced into any part of the-body.

Still more particularly, the invention deals with an element of the character described, which creates a secondary pressure upon the body, thus minimizing the feeling of the needle injection into the body.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

Fig. 1- is a diagrammatic side view of one type of syringe showing, in section, one form of deception element arranged thereon and indicating contracted position of element in dotted lines.

Fig. 2 is a sectional view through a modified form of element, indicating the element in different position in dotted lines and diagrammatically showing the needle end only of -a syringe.

Fig. 3 is a side elevation of another form of element which I employ detached, with part of the construction broken away and in section.

Fig. 4 is a bottom plan View of the structure shown in Fig. 3; and

Fig.5 is a sectional detailed view of the upper end por-.

tion of an element, illustrating a different method of at' tachrnent to a syringe, part of the syringe being illustrated in elevation.

While my deception elements are applicable for use on syringes of various types and kinds, in illustrating one adaptation of my invention I have shown at 10, iu Fig. 1 of the drawing, a Luer-lock 'type of syringe, in which'the usual plunger 11 is movably mounted. At 12 I have shown the Luer-lock coupling of the syringe, at 13 the coupling end of a needle 14, the end 13 being attachable with the Luer-lock 12, as with other devices of this type and kind. At 15 I have shown, in Fig. 1 of the drawmg, in section, one of my improved deception or envelo ing elements, the element 15 comprising a flexible wall tube composed of rubber or plastic material having an inwardly curled or annular beaded upper end portion 16 adapted to securely grip the Luer-lock 12 in supporting the element 15 on the syringe with the lower end 17 of the element protruding slightly beyond the lower pointed end 18 of the needle 14. The lower end portionof the element 15 has, on its inner surface, an insert 19 with a downwardly contracted bore 20 to guide the element 15 in its movement upwardly over the needle 14 from the extended position shown in full lines to a contracted position, as diagrammatically illustrated in dotted lines in the 2,845,065 Patented July 29, 1958 "ice such as to roll up over the syringe 10 in the manner dia-' grammatically shown and can be readily returned to its normal extended position by manual operation. In other words, this folding operation simulates that of the stripping of the finger of a rubber glove from the finger of the hand with the exception that no pressure is required. The firm engagement at 16 will allow the freely flexing tube to fold in the manner diagrammatically illustrated. The upper portion of the element 15 has a vent passage 21 for discharge of air in the contracted movement of the element.

In Fig. 2 of the drawing, I have shown a modified form of element 22 which differs from the element 15 in being conical in form, that is to say, the lower end portion 23 is of greater diameter than the upper inwardly curled end portion 24, the end portion 24 being similar to the curled end 16. At 25 I have shown a vent, similar to the vent 21. In Fig. 2, the structure is further modified in providing, at the lower end 23 of the element 22, a transverse rubber diaphragm 26 suitably fixed at the periphery of the element 22, as seen at 27, the diaphragm completely concealing the needle 14/, similar to the needle 14 and, in' operation, the needle pierces the diaphragm, the diaphragm being of such structure as to seal itself after the needle has been withdrawn therefrom, or returned to the position shown in Fig. 2. With the structure shown in Fig. 2, the element 22, in contraction, will move substantially into the position indicated in dotted lines in said figure.

In Figs. 3 and 4 of the drawing, 1 have shown another adaptation of my invention, wherein the element 28 is somewhat conical in form and is preferably moulded from highly flexible rubber or plastic material to represent an amusing character, such for example as a little man having his hands 29 disposed over his ears and with a smiling face 30. The upper head or hat end 31 of the element will have the inturned or rolled end 32, similar to the ends 16 and 24 for mounting on the syringe with a vent 33 closely adjacent said end. The lower flared end portion 34 of the element can be shaped and otherwise characterized to represent the feet 35 of the little man.

The end 34 will preferably be of elliptical forrrnas noted in Fig. 4 of the drawing; whereas, the body portion of the element can be cylindrical, as evident from the line 36 of Fig, 4, but contracted to the upper end to form a substantially conical portion which will contract substantially in the manner illustrated in Fig. 2 of the drawmg.

portion of an element which may be similar to any one of the elements 15, 22, 28 and which differs from the other elements in having a special beaded upper end 38, grooved, as seen at 39, to receive an annular flange portiondll formed on any suitable part of the syringe structure. In

the present showing, the flange 40 is formed on part of a Luer-lock casing 12', similar to the Luer-lock 12. At 41 is shown a vent, similar to the other vents employed in order to relieve air in movement of the element into its raised or contracted position.

The type of device diagrammatically portrayed in Fig. 3 of the drawing is designed for use primarily in dealing with injections given to small children so as to draw attention of the child to the deceptive element as a little character who is going to help them in their momentary trouble. Most people, however, rather fear the approach of a needle to the body in the operation of giving them an injection, thus with other more modified forms of In Fig. 5 of the drawing, I have shown at 37 the upper devices, such as the elements 15 and 22, here again, the needle is shielded and a relatively large body is brought into engagement with the flesh, so as to remove the optical or mental fear of the injection operation.

It will be understood that various types and kinds of deceptive or enveloping elements can be utilized on syringes of many types and kinds. However, in all instances, it will be desirable to employ an element movable longitudinally with respect to the needle so as to contract in projection of the needle into the body, the degree of contraction being governed solely by the extent of insertion of the needle into the body, it being understood that pressure of the element upon the body moves the same into its collapsed or contracted positions.

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