HYPODERMIC AND SPINAL SYRINGE July 3, 1951 2 Sheets-Sheet 2 Filed March 9, 1950 INVENTOR. War s Patented July 3, 1 951 HYPODERMIC AND SPINAL SYRINGE I 7 Anthony J. Son, Boston, Mass, assignor to Sonco,
Inc., Mattapan, Mass., a corporation of Massachusetts Application March 9, 1950, Serial No. 148,552
, 3 Claims. 1
This invention relates to subcutaneous injection instruments and more especially to those of the types known as hypodermic syringes and spinal syringes.
One object of the invention is the provision of a new and improved clamp for securing together the needle guard and the needle hub of a hypodermic syringe and an improved finger grip curved to accommodate the fingers of the operator.
A second object is the provision of a syringe that may be used as an ordinary hypodermic syringe or as a spinal syringe and which has an improved finger grip of a type different from that used in the customary hypodermic syringe and which also is curved to accommodate the fingers of the operator.
A third object is the provision of a spinal syring'e in which the needle has a combined hub and finger grip. With these and other objects in view, my invention consists of the novel features, parts, and combination of parts, which are particularly described in connection with the accompanying drawings illustrating syringes that have given good results in practice.
In the drawings accompanying and forming a part of this specification,
Figure 1 is a sectional view of a hypodermic syringe embodying my invention.
Fig. 2 is an elevation of the clamp that secures together the needle guard and hub.
Fig. 3 is a horizontal section of said clamp.
Fig. 4 is a plan view of the finger grip.
Fig. 5 is an elevation on an enlarged scale of the needle hub and finger grip.
Fig. 6 is a sectional view of a combined spinal and hypodermic syringe embodying my invention.
Fig. 7 is a sectional view of a spinal syringe having a combined needle hub and finger grip.
In the particular drawings selected for more fully disclosing my invention and the principles underlying the same, said drawings to be considered as illustrative, merely, and not restrictive, I is the syringe body of the type that contains the injection fluid and the piston (not shown) whereby the said fluid is forced through the needle H, which needle has a hub I2 to which is rigidly secured the finger grip 13. The inner end of the hub has a tapered bore M for receiving the tapered nipple l5, said bore and nipple constituting a Luer slip joint.
The clasp l4 embraces the forward end N of the hub and also the rearward end of the guard I], which elements are detachably secured together when the screw I8 is tightened. The
guard employed in the present instance consists of a rod member, the lower portion of which is parallel to the axis of the needle and is spaced away therefrom. The upper portion of said guard is curved toward the needle and is then bent to form a short end portion co-axial with the same. The forward end of the guard is bored to receive the needle as indicated at l9 and terminates in the button 20 which governs the amount of penetration of the needle. Preferably, the needle guard is graduated, as shown at 2|.
In operation, the hub is secured to the syringe body by the Luer slip joint, the screw [8 is loosened, the rod placed in the longitudinal position desired and then the screw is tightened. In joining the hub to the syringe body, the forefinger and thumb of the operators left hand grasp the finger grip l 3, the nipple is inserted in the bore 14 and either the syringe body rotated in one direction and the hub in the other, or else the hub is held stationary and the syringe body rotated and pushed forward, or the syringe body is held stationary and the hub rotated and forced downwardly. It has been proposed to make a. somewhat similar finger grip with two finger contact portions extending oppositely in planes tangential to the circle of rotation of the syringe tip. In the present instance, however, the finger grip l3 has oppositely disposed curvilinear flanges that are symmetrical with respect to a central vertical plane passing through the axis of the hub. This arrangement has been found much easier to manufacture than the finger grip of the prior art above mentioned and to be easier on the thumb and finger of the operator.
In Figure 6, there is illustrated a combined spinal and hypodermic syringe having the usual syringe body, the usual Luer slip joint and an adapter 25 which has two oppositely disposed arms 26, 26, each curved as shown to accommodate the fingers of the operator. The adapter has a frustoconical projection 21 extending from the forward face of the finger grip and disposed in the central conical cavity 28 of the hub 229 Passing through a hole in the outer edge of one of the arms 26 is a guard rod 30 which may be secured in longitudinally adjusted position by the screw 3|. Preferably, the guard rod is graduated, as indicated at 32. The rearward portion of the guard rod is parallel to the needle'and spaced away therefrom and the forward end portion thereof is bent toward the needle and terminates in the bead 33 which is coaxial with 3 the needle and through which the needle proiects.
In operation as a hypodermic syringe of the usual kind, a quantity of injection fluid is placed in the syringe body and is forced through the needle in the usual way by a plunger, not shown. When used as a spinal'syringe, the syringe body is detached from the adapter, the injection fluid placed therein, the adapter with the attached grip having the same conformation 'as that shown in Fig. 6. The guard 30 is detachably secured to the combined hub and finger grip in the same' manner as in the needle illustrated in Fig. 6 and terminates in the penetration governing bead 3|. By virtue of the curvilinear conformation of the arms of the finger grip, it is much more convenient for the physician to insert the needle with its curved finger grip than in the case of the spinal syringes of the prior art.
Having thus described illustrative embodiments of my invention without, however, limiting the same thereto, various modifications within the purview of the appended claims being permissible, what I claim and desire to secure b Letters Patent is:
1. A hypodermic syringe comprising in combination, a syringe body, an injection needle, a hub fixedly secured to said needle, means for detachably securing said hub to said syringe body, a needle guard, said guard consisting of a rod member, the lower portion of which is parallel with the axis of said needle and spaced away therefrom, and the upper portion of which is coaxial with said needle and provided with a bore for receiving the same, and clamping means for detachably securing together said guard and hub, the lower portion of said guard passing through said clamping means.
2. A combined spinal and hypodermic syringe comprising in combination, a syringe body having a hollow frustoconical projection on its for- 4 ward end, an injection needle, a hub fixedly secured to said needle, an adapter interposed between said syringe body and said hub, said adapter comprising a double-arm finger grip, a hollow frustoconical projection extending from the forward face thereof and disposed in a central cavity in said hub, a guard rod passing through a hole near the outer edge of one of the arms of said finger grip, means for securing said rod in adjusted position with respect to said finger grip, the rearward portion of said rod being parallel to said needle and spaced away therefrom, and the forward end portion of said rod being bent toward said needle and terminating in a bead having a bore coaxial with said needle.
3. A spinal syringe comprisingin combination, a syringe body having a hollow frustoconical projection on its forward end, an injection needle, a combined hub and finger grip fixedly secured to said needle, said combined hub and finger grip comprising two oppositely disposed arms and a boss on the rearward face thereof, said boss having a central conical cavity adapted to receive the frustoccnical projection on said syringe body, a guard rod passing through a hole near the outer edge of one of the arms of said combined hub and finger grip, means for securing said rod in adjusted position with respect to said combined hub and finger grip, the rearward portion of said rod being parallel to said needle and spaced away therefrom and the forward end portion of said rod being bent toward said needle and terminating in a bead having a bore coaxial with said needle,
