SYRINGE CARTRIDGE Filed Feb. 14. 1927 novel Way. For this Patented Aug. 4, 193i IRVING KULIK, OF BROOKLYN, NEW YORK, ASSIGNOR TO OF CHICAGO ILLINOIS, A CGRPORATION G2? SYRIN GE CARTRIDGE Application filed February 1%, 1927.
This invention relates to cartridges for hypodermic syringes.
A cartridge of the kind referred to usually consists of a glass tube sealed by rubber stoppers which confine a charge of hypodermic fluid between them. When used in a syringe instrument for administering a by podermic injection, the front cartridge stopper is pierced by the inner end of the syringe needle or a canula in communication therewith, and the syringe plunger drives the rear stopper into or through the cartridge tube for forcibly ejecting the fluid contents through the needle. In this action the pressure applied through the plunger thrusts the cartridge forward against the front head of the syringe barrel. It is desirable to protect the front end of the glass tube from breakage by interposing a suitable cushioning meansbetween the tube and the front head ofthe syringe barrel. Expedients for this purpose have heretofore been employed. The present invention, however, provides for sealing, cushioning and protecting the front end of the cartridge tube in a purpose the front cartridge stopper is constructed with a notched tubular end protruding beyond the end of the glass tube and adapted to be bent thereover when the cartridge is subjected to the operating pressure in a syringe instrument. For illustration, reference is made to the accompanying drawings in which:
Fig. 1 is .a longitudinal sectional view of a cartridge embodying'the invention.
Fig. 2 is a sectional View of the pierceable front stopper of said cartridge.
Fig. 3 is a similar view of another form offront stopper. In the drawings, A denotes the cartridge tube, B the pierceable front stopper, and C the rear stopper or plunger plug which is to be forced into the tube by the syringe plunger to expel the fluid contents of the cartridge through the needle or canula that pierces the stopper B.
The pierceable front stopper B is shown as a tubular body with an intermediate diaphragm 3 to be pierced by the needle or canula. By this construction the stopper COOK LABORATORIES, INC.,
DELAWARE Serial No. 168,169.
is provided with an inwardly facing recess well as with the outwardly facing reces l, consequently in the fluidejecting op e when the annular wall of the stopper sur- 1 rounding the rec of the stopper in sealing effect.
- which protrudes tri d beyond the end of the cartube, is formed with a tapered edge at 4, and with diametrically opposite notches one of which is cartridge is forc administering notched 7 operation, end of the stopper B bearing indicated at hen the ed forward in the e ection the protruding end of thecartridge tube,
protecting the same against breakage and preventing leakage. This notches 5 open is allowed by the fact that the up more and more the pressure upon the cartridge increases.
The modified 131, shown in Fig.
notched portion form of pierceable stopper 3, has its outer tubular so interiorly formed so as to provide undercut portions 4%. If this stopper be used recess 2 facing notched portion of the cartridge tridge is forced outward in the cartridge with the inwardly and the tubular protruding beyond the end tube, then when the can forward there will be an displacement of the portions 400 so as to spread over the end of the tube.
As indicated at stopper groove instead groove.
WVhat I claim by Letters Paten 1. A syringe 0 ed liquid stopper to fitted in th may be provided with G in Fig. l, the plunger 7 a spiral of the ordinary annular as new and wish to secure t is:
artridge comprising a sealcontaining tube embodying a be pierced by a needle or canula e fore end of the tube, the cartridge being constructed to have its interior volume reduced for ejecting the liquid through the needle, said stopper having a notched tubular protrusion beyond the fore end of the tube adapted to be bent over the end of the tube to cushion the same when the cartridge is employed in a syringe instrument. v
2. A syringe cartridge comprising a liquid containing tube having stoppers, one adapted to be forced inward to eject the liquid through'a needle or canula thrust through the opposite stopper, and the last mentioned stopper having a notched tubular portion protruding beyond the end of 1 the tube and adapted to be bent over the end of the tube so as to cushion the same When the cartridge is employed in a syringe instrument.
