Application January 17, 1948, Serial No. 2,900V
9 claims. Y (ol. 12s-220) This invention relates to a hypodermic syringe.
The general object of the invention isto provide an improved hypodermic syringe of the disposable type in which the parts are Vof such a nature that they can be readily manufactured and assembled. v
Another object of the invention is to provide a novel front member for a syringe.
A further object of the invention is to provide a hypodermic syringe including novel means for preventing premature or accidental movement of the parts of the syringe. l Y
Other objects and advantages of the invention will be apparent from the following description .y
Referring to the drawing by reference charv, acters, I have shown my invention as rembodied in a hypodermic syringe which is indicated generally at l. As shown the syringe is of the disposable type and includes an ampule or barrel Il' and a plunger yIl'. The barrel may be made of tubular material such as glass and has a rubber stopper I3' in kone end. The stopper-includes an axial recess I4' and an axial depression l5. with a diaphragm I6 between the recess and the The needle includes la xed hub 52 which'has a head 53' thereon, normally arranged in the recess 38. The head 53 is shown Vas beveled to correspond to the bevel 39' of the recess. The hub includes a finger engaginghead portion 55 by means of which the needle may be moved so that the head 53' passesinto the recess 31', at which timeY the" diaphragm 21 .will have been pierced by the tip Ela' of the needle. l v
I provide a cap member 65 'which serves to protect the hypodermic needleduring shipment and prior to use. This cap member hasv a' bore 66 which receives vthe needle, and-the end G'Lof the-cap-member engages thehub 55 when in normal position. To prevent premature piercing of the diaphragm 2l' by 'the :inner end of the needle, I provide a seal member, indicated generally at 68'and which may 'consistof a strip of adhesive tape 69 to which a'block 10 is secured. This block I0 may be oi. plastic material and ts between the end 1I 'of' the plunger tip and the shoulder 12 at the inner end of the hub 55' and thus prevents axial inward mo'vement of. the hub. The free end 13 Vof the seal engages the cap member 65 and includes a finger engaging releasing tab 14. The nger engaging tab "I4 may be made by Vfolding the en'd ofthe strip upon itself.;V v
The seal .member 68 further may include a 'block 15 lwhich engages theflange :30' and the end 'I6 Vof the. ampule! l I',and normally prevents depression. 'The stopper includes aange jl.
The plunger l2' includes aninnerend Vwhich is recessed at 60 to receive the bodylofa piston stopper 6| which has peripheral beads 62 thereon at the inner end thereof. The stopperii I .is preferably made of rubber and has axial recesses 25 Y member which is shaped to provide a finger engaging ange and has a bore 3l which receives the body of a front end closure 32which is preferably made of rubber and includes a rounded iront end tip 33. The closure 32 includes an inner axial recess 34' separated by a diaphragm 35 from an axial recess 36' which communicates with another axial recess 31. The recess 31 communicates with a recess 38', the inner wall of the recess 38' being beveled as at 39'. A hole 40 aiords communication between the outerV recess 38 land the end of the tip 33'. .A
The plunger I2 has an axial bore 50 inwhich I arrange a hypodermic needle 5|. Thisv needle has a sharpened tip 5P" disposed normally adjacent the diaphragm 21' and is adapted to pierce the diaphragm to place the needle in communication with the contents of the ampule when the needle is moved axially along the plunger.

.In use the syringe is preparedv so 'thatfitis in the condition shown -in .Fig.f1. The operator Vthengrasps thetab'd'of the 'seal andstrips away the seal, firstv re'riioi'riiigv the block 'IIJ and` thus `allowin`gth cap memberli to be pushed and l5 byA further` moving the seal'y 68.. permits the plunger'vto move into-thel ampule."
