(ci. lesa-215) This invention relates to hypodermic ampoule syringe constructions ofthe unitary kind. Such constructions usually comprisera collapsible tube,
"onfwhich the hypodermic needle is mounted.
The object ofthe presentinvention isrto Iensure that during. the storage' stage; theV needle .or the ypart for supporing itis sealed against contamination from outside sources and that oncethe seal is destroyed it cannot be restored. The inven- 1 tion inits broadest as-pect consists in rproviding with an extension so that a the collapsible tube in the storage state,
vneedle with' or without the needle itself.
f 4In order that the invention may be the more clearlyunderstood a syringe in accordance there- `with will now be described, reference being made to the 'accompanying` drawings, wherein:
Figurel` is a sectional elevation of the'syringe f in the storage state.`
"an integral tubular envelope of say sof-t'v metal la. and Ib by means of two portions 'divided into diaphragm 2. The portion laof said the portion Ibis a *nozzle abuts against the diaphragm and'is sealed al] 'f' around the wall of the envelope. The upper portion of said nozzle element forms a nozzle `coaxial An axial bore hole-'4 passes the nozzle element 3-from the with the envelope. completely through *base end to the nozzle end thereof.
The hypodermic needle5 has its base eridsealed j in one closed end of a hollow more-oriless'r cylinsaid needle rests against the diaphragm v2. In
` this positionthe mount 6 will be held clearA of the nozzle portion of the nozzle element asshown.
v-lietween the base portion 3a and the-*nozzle portion of the ,nozzle element 3, said nozzle element is formed with an annular ledge or shoulder 3b (Figure 2) and a tube 1 of say glass, with one end openand the other end closed, is arranged in an inverted state over the nozzle portioni.and theprojectingneedle and mount, with its 7rim resting on the ledge or shoulder 3b. Thefitfof the tube 1 over the upper portion of the nozzle element may be quite loose, and the fit` of ythe needle 5 in the bore hole 4 is also quite loose, but the dimensions are such that the tube 'I isretained more-or-less in place by the upper portion Ib ofthe envelope, and the needle is retained in the bore hole by the tube 1. No amount of shaking will cause the needle to puncture the diaphragm 2, and the glass-tube Tprotects the container portion Ib against collapse.
It will be seen that the needle is completely enclosedl in the sealed upper portion lb and that,
Y. vided between said two portions.
however long the device may be kept before use, the needle must remain sterile. In like manner the liquid to be injected is completelyenclosed in the hermetically sealed lower portion la and must always remain sterile. When the device is to be used,- the upper portion Ib is held between the fingers and squeezed against the tube 1 and is then torn off and removed together with the tube. Subsequently the needle 5 is first pressed down so as to puncture the diaphragm 2 and make a way of communication for the liquid to passup the hole 4, and said needle is then removed from .the hole 4 and the inverted mount 6 is force-fitted on the nozzle portion of the element 3 as shown in Figurei4. Thus, when the envelope portion la is squeezed, the liquid is forced through the borehole 4, through the holderv 6 and up the bore of the needle.
' Turning now to Figure 2, which shows the Way in which the device is constructed, it will rbe seen that the envelope is rst made with its upper endthat is the end of the portion lla-open.' Moreover the portion lb is of slightly larger diameter than the portion la so that a shoulder lc is pro- Moreover the diaphragm 2 is in the form of aninverte'd pill box, having an annular wall 2a which upstands from the perimeter of the diaphragm proper. In construction the diaphragm 2 is rst iittedron to the base portion 3a of the nozzle element `3 and the two parts are together slid into the upper envelope portion |-b so that the diaphragm proper rests on the shoulder Ic, and the wall 2a of said diaphragm fits within the wall of said envelope portion Ib'. i The Vdiaphragm and nozzle are then tightly clamped inplace by means of a clamping element 8. This clamping element consists of a sleeve with one end 8a slightly inturned and it is slid up the container portion I a, with its inturned end lowermost (the aperture within the inturned end being large enough for this) until said inturned end seats against the under side of the shoulder Ic. The dimensions are such that, in this position, the wall oflthe'zenvlope portion "'I b andlth'e wall portion 2a"of the diaphragm are tightly clamped between the sleeve 8 and the base portion 3a of the nozzle element. base portion may be slightlyrconed-fto,` enhance this effect.
The needle and its mount-,l-andralsof'thetube `'I are then placed in position as described, 'and`V finally the upper end of thecenvelopepontion -Ib is closed and sealed by bringing l"xthe'top wedges together, clamping them and hermeticallyseal-` ing, if necessary, by dipping into solder of`low melting point. The Ineedle mount 6 and the --Jntz'alfe element 3 may be of plasticv material. Y A{In-'somecases the usery of the device'fwill him- "'#slflhave asupply of sterile hypodermicneedles andmay thereforey not requirel a hypodermic needletofbefsupplied with the device. To meet the requirements offsuchy cases the needle, togeth 3r Y'=with`-its mount'-an'd also the tube l, maybe --fomitted. 'The-'envelope p-ortion-lbwillbe sealed f-^as`beforeand thus yit will be ensured that the 'wh'ole of fthenozzleelement 3 will be kept sterile. Theuserfwilli-tear'oii the portionv Ib as before andwill then'puncture the diaphragm-'with his l'own sterile nee`dle^ which he will f then V'mount on ff'thenozzle element. "The device without the nee- Ldlecanobviouslybe-'supplied at a reduced cost.
It is to be understood that 'theneedle may be -'=permanently falixedY in place, in which case, after ithe'portion `Ib is ruptured, the diaphragm would "ffbeipuncturled by means-"efr a stiletto passed down 17thefboreof the needle.
