SYRINGE Filed Feb. 25, 1950 Vuren GERARD AsTle/v JNVENTOR.

MFM e f Patented Oct. 16, 1951 UNITED STATES PATENT OFFICE SYRINGE Victor Gerard Bastien, New York, N. Y.

Application February 25, 1950, Serial N o. 146,241

1 Claim. l

My invention relates to an improvement in different types of syringes used in the medical and dental professions and the object of the improvement is to provide a syringe in which the needle is hidden from the view of the patient until the actual moment when the drug or medicine contained therein is injected into the patient. The obj ect of my invention is to provide such a syringe in which the operation of uncovering the needle and injecting the contents may be accomplished by the operator using only one hand for such purpose.

Further objects and advantages of my invention will appear in this specification and on the drawings.

I attain these objects by the device illustrated in the accompanying drawing in which Figure l is a plan view of the entire device; Figure 2 is a partial cross-section view of the device, along the line indicated by the numerals 2 and 21 in Figure 1, showing the needle-covering sheath in position covering the needle; and Figure 3, a partial crosssection view showing the needle-covering sheath drawn up on the barrel of the syringe leaving the needle free for use.

The syringe comprises the following parts: A sheath I, of opaque material having an annular opening at one end thereof through which the syringe needle can pass; finger supports 2, at the end of the sheath to enable the operator to adjust same; a latch 3 for which a slit is provided in the sheath I; a syringe needle 4; a plunger 5; a syringe barrel 6; two annular grooves on the syringe barrel 'I and la, which are adapted tc receive the inner edge of the latch 3; and a spring mechanism 8, provided to maintain the latch 3 in its position in the slit in the sheath I with sufflcient tension to lock the sheath I in fixed position when the inner edge of the latch 3 rests in either of the annular grooves 'I or la.

In practice I use a V-shaped Wedge for the latch 3 designed to fit in either of the annular grooves I and la. The tension of the spring 8 should be suicient to maintain the latch 3 in position in the annular grooves 'I and 1a and yet sufliciently slack so as to permit the latch 3 to pop out of either of the annular grooves 'I or la upon the manipulation of sheath I by the operator by finger pressure on the nger supports 2.

The syringe is loaded with the type of drug or medicine which has been prescribed. The sheath I then is set in position as shown in Figure 2 of the drawing, covering the syringe needle 4 from the view of the patient. The operator at the moment of injecting the contents of the syringe moves the position of the sheath I.to that as shown in Figure 3 of the drawing by using the middle nger of the Vhand in which he holds the syringe, drawing the sheath I up by pressure of the said finger on the finger supports 2. The latch 3 pops out of the annular groove 'I and locks the device by its contact with the annular groove la. The syringe needle 6 is then completely exposed and is injected into the patient. The contents of the syringe are then emptied by means of pressure of the operators thumb on the plunger 5.

While a preferred form of the invention in all its respects has been described, there are equivalent constructions which may be employed withcut leaving the scope of the invention as set forth herein and I do not want to be limited to the exact details as set forth herein but wish to be protected for all constructions within the limits of the claim following. Aside from being an entirely new improvement in the construction of a syringe of the character described herein, my invention is particularly helpful for treating children, patients with nervous disorders or any patient who would be frightened by the sight of a needle. The method of injection thus becomes much more simple from the point of view of both the patient and the operator and will prevent many accidents. This is especially true where oral injections are necessary and the patients are uncooperative.

Wherefore, I claim:

A syringe of the character described comprising a hollow cylindrical syringe barrel, said hollow syringe barrel having a plurality of annular grooves spaced along its exterior surface, a plunger designed to fit snugly within the syringe barrel, a syringe needle adapted to flt at one end of the syringe barrel, and having a cylindrical sheath adapted to slide over and cover the outer walls of the said syringe barrel and the syringe needle, said sheath having an annular opening at one end through which the syringe needle may pass, a latch relatively near the other end and adapted to stop at fixed points along the syringe barrel in the said annular grooves of the said syringe barrel, said latch being maintained in position by means of a tensioning device.

VICTOR GERARD BASTIEN.
