Application February 24, 1945,. Serial No. 579,663'

1 claim. (prize-aix) syringe including" a barrel and including a piv oted closure wherein novel-means is provided for holding the closure in closed position.

A further object of the invention is to provide a syringe with a barrel having an am'puIetherein with a cork in the ampule which contains a drug, and wherein the barrel includes a novel pivotaliy mounted front member which is movable to cause release of a drug in the ampule cork.

Other objects and the advantages of my invention will be apparent from the following description taken in connection with the accompanying drawings, wherein:

Fig. 1 is a central, sectional view showing a syringe embodying the features of my invention;

Fig. 2 is a fragmentary view of the syringe similar to Fig. 1, showing the front member partly closed;

Fig. 3 is a view similar to Fig. 2, showing the front member in more fully closed position;

Fig. 4 is a view similar to Fig. l, showing the front member in fully closed position;

Fig. 5 is an end View of the barrel, with the front member removed;

Fig. 6 is an end view of the syringe iront member removed from the barrel;

Fig. 7 is a plan view of the iront member holding dog;

Fig. 8 is a side elevation of the front member holding dog;

Fig. 9 is a plan view of the ampule holding dog, and

Fig. 10 is a front elevation of the ampule holding dog.

Referring to the drawings by reference characters, I have shown my invention as embodied in a syringe which is indicated generally at III. As shown the syringe includes a barrel II having an enlarged elliptical front end I2 and a cylindrical portion I3. The rear portion I3 is closed as at I4 and the closed end is provided with a hole I5 through which a plunger I6 extends.

The plunger I6 is provided with a hand engaging portion I'I at its outer end and at its inner end includes a head` [8. A sleeve. lll is slidable on the plunger and is. engaged by the inner end of the spring 20. The. outer end of the. spring 20 engages the inner wall oi the end I4 of the barrel.

My improved syringe is particularly adapted for use in the preparation of fresh anaethetizing solutions and. is adapted for use with ampules which may be the typel shown in my prior Patent No. 2,337,354, granted December 21, 1942.v Inthe disclosure the ampule designated at 2.0' has a piston stopper 2| at the inner end which 'is adapted to be engaged by the plunger head [8 and to be forced inwardly alongthe ampule to expel the contents thereof.

At the forward end of the ampule I provide a stopper 22 which is provided with a diaphragm 23 and with a cavity 24 in which a medicinal tablet 25 is arranged. The inner end of the cavity 24 is closed by a closure 2B which is in the nature of a disc and which normally .Seals in the drug 25 so that it will not be reached by. the liquid vehicle within the ampule 2Dfuntil the closure 26 is dislodged.

The forward end of the front portion I2 is provided with a slot 30 in which a finger 3| on a iront member 32 is inserted and is pivotally mounted by means of a pin 33. The closure 32 includes an outer end portion 34 which is adapted to be' engaged by hypodermic needle support 35. The front member includes a hole 36 which communicates with a tube 31 which projects inwardly beyond a shoulder 38 on the closure 32.

The construction is such that when the closure 32 is moved towards closed position it lirst assumes the position shown in Fig. 2, wherein the diaphragm 23 is engaged by the tube. As the closure moves towards completely closed position the diaphragm will be broken and the tube will engage the closure 26 as shown in Fig. 3. Further movement of the closure will cause the disc closure 26 to be unseated as shown in Fig. 4. This act allows the drug to enter the vehicl and prepare a fresh solution. y

To hold the ampule 20 in the barrel while the closure is being moved to closed position, I pro-f vide a dog 40 which has a projection 4I at the front end and this projection is positioned to.

engage the forward end of the ampule 20' as shown in Figs. 1, 2 and 3. When the closure 32 is moved to fully closed position the projection 4I is received in a recess 43 in the closure 32 and the projectionSB on the closure 32 engages the end of the ampule 20 and causes it to move slightly inwardly. In this way there is a large contacting area for the iront end of the ampule f2 i j i Y and the latter is not likely to break as would be they case if only the dog portion 4| engaged the ampule during the time the piston cork 2| is 'l moved forwardly.

To hold the closure 32 in closed position, I prov Y vide a dog 45. The dogs 40 and 45 are coaxial and are mounted on a pivot pin 46. The dog 40 is U-shaped, as shown in Fig, 10, while the dog 45 is of a single thickness and ts between the sides of the U-shaped dog. The dog 45 includes a tongue 41 'which engages a tongue 48 on the Y Y front member 32 when the latter isk closed.

In the use of my improved syringe an ampule is inserted in theY barrel and is moved to the posi- Y tion shown in Fig.V 1, where it is held by the dog 40. The closure 32 is then moved to closed position and as it moves the tubeV 31 moves inwardly and engages the diaphragm 23 ,(FigrZ). Then thel tube breaks or pierces the Vdiaphragm (Fig. 3) Then the tube dislodges the closure 25 to i :pause the drug 25 to beexposed in the stopper To discharge the ampule and reload the syringe thevdogV 45 is rst depressed, This causes the closure l32 to be moved by a spring 5I to open position. VThereupon the dog 40'is. moved outwardly and theampule is ejected by action of the spring 2U. Y

The dog 40 is arranged inra slot 60 Ywhich is slightly wider than the thickness of the dogV so 'that a spring 5| maybe arranged about. the pin 446 at one side of the dog 40. One end of the spring is bent to iit in a holein the Vdog 40 and the other Yerld of the spring is bent to fit in a hole in the Adog 45V and the spring normally urges the dog 45 outwardly and the dog 40 inwardly.

Vaeaaloo 'Y A spring normally urges the front member to open position.

- 1t will be noteathat the dog 4o cannotlaeV moved outwardly so long as the front member is in closed position and this dog cannot therefore be released until the front member is open.

Thus premature ejection of the ampule from the barrel before the tube 31 has Vmoved from the ving sleeve slidable on the'plulflger,v spring means normally urgingthe ampule engaging sleeve forwardly in the barrel, a pivoted dog on the front 'end of s-aid barrel, said dog having a projection thereon, an ampule in said'b'arrel and engaged by Ysaid projection,` Ysaid ampule having a cork therein adjacent said dog, said cork havingr a drug holding cavity therein, a closure for'said cork'cavity, a front member pivotally mounted on said barrel, said front member having aV tube projecting therefrom and movable into the barrel Vfor the purpose of shifting said cork cavity closure when the front member is moved to closed position, a second dog pivoted on said barrel, said front member having a projection thereon engaging said second dog, said front member having a recess therein receiving said flrst dog when the front member is closed, said front member having a shoulder portion thereon which engages the end of the ampule and forces the ampule into the barrel and away from the first dog when the front member is closed, and spring means urging said dogs to engaging position.
