Anni Sack, Basel, Switzerland ApplicationApril .4, 1941, Serial No. 386,933 g In Switzerland May .6, 194.0
tion allows separate cleaning of the head part and facilitates the filling of the ampulla, While the transparency of the body thereof makes possible a constant check upon the purity of its content.
In the modification of Fig. 2, the body a of the liquid-container is closed at the upper end by I a thin closure plate f provided with a peripheral a convenient cellulose material or transparent chlorinated caoutchouc or any other similar'substance provided that the same is transparent and compressible and in general possesses the properties required for ampullae. An injection needle may be removably connected to the head portion of the container by screw threads or other connecting means. The rigid part of the liquid-container can itself be so formed that the fixation of a usual injection-needle thereon will be possible without difliculties. Furthermore, the head part of the liquid-container can also be constructed as a receptacle with pierceable bottom for the reception of a powdered dry substance or as a receptacle with pierceable bottom for the reception of a liquid solvent for a dry substance within the container body.
The accompanying drawing represents several embodiments of the improved ampulla-syringe.
Fig. 1 shows the preferred form of the present ampulla in longitudinal section.
Fig. 2 shows in longitudinal section a second form of the ampulla embodying the present invention.
Fig. 3 represents a further form of the ampulla in longitudinal section; while Fig. 4 shows still another form of the ampulla in longitudinal section. v
Fig. 5 represents a convenient piercing needle.
In the form of Fig. 1, a indicates the body of the liquid-container, which consists of transparent, compressible material of the above kind and is provided with a'rigid head part. The head part b terminates in a socket c which is closed before use of the ampulla by means of a thin closing member (1. The latter can. be pierced or torn-01f for the use of the ampulla. In this example it has the form of a cup, but it could also consist of a simple closure film or a closure film with a tearing-off ear or the like. The socket c is designed to receive and removably hold a hollow injection-needle, for example by putting, threading or fixing otherwise the same thereon.
The head part b of the ampulla is removably connected with the body a of the liquid-container by means of a screw thread 6 so that it can beremoved therefrom. The said movable connecscrew thread g for receiving the threaded head part b of the container and designed to separate the interior of said liquid-container from the interior of the head part b. The plate f is itself screwthreadedly mounted on the body a, as clearly shown in Fig. 2.
In the embodiment of Fig. 3, the body a of the liquid-container is closed by a closure piece It provided with a funnel-like cavity to form a receptacle 0r compartment with a thin bottom h for receiving a powdered dry substance. In the body a itself there is a liquid for dissolving the dry substance, for example Water. The cavity of the closure piece it is closed at the top by a closing plate h The head part b with the socket c for receiving the injection-needle is screwed on the closure piece h. when the thin closing members h and h, of the closure piece 71. are pierced, the dry substance runs down through the formed orifice into the liquid solvent in which it dissolves itself. In this example, the closure film d of the socket c is shown provided with a tearing-off ear d The embodiment of Fig. 4 is similar to thatof Fig. 3. The head part b constitutes a liquidvessel or compartment with thin pierceable bottom 2', whilst the body a of the liquid-container tion of that of Fig. 2, for use of the ampullasyringe, the closing film of the socket c is pierced or removed and then the latter is provided with an injection-needle of known kind. In Fig, 2, the injection-needle x is rigidly connected with the socket 0.
Before using the ampulla-syringe in this case, the closing plate 1 is pierced by means of a piercing needle y represented in Fig. 5. In a similar manner will be effected the piercing of the closing membrane parts h h in Fig. 3 or i in Fig. 4. By compressing the transparent body a of the container by hand or by means of a pressure device, the contents of the container can easily be injected.
In all the examples, the transparency of the container body aifords a great advantage over the known syringes Where the container body consists for example of compressible tin inasmuch as the constant vision of the liquid is possible. Also the fabrication of the improved syringe is simpler 1 and cheaper than in the case of metal ampullae.
Finally the injection-needle, which is to be disinfected for use, can be employed several times,
whilst in the usual ampullae-syringeslit 'ca'njonly once be used.
What I claim is:
1. Anampulla-syringe comprising a liquideconj t l tainer having a body of transparent, compres sible material, a rigid hollow head partthereon and subject to pressure upon compression of saicl I body, means on said head partfor supporting,
an injection needle, and means removably inter-' 1 connecting said body and head part {While :securely retaining the same in interconnected rela- 2,404,316 v:i jg:
tionship against the influence of the pressure generated upon the compression of said body, said last-namedmeans comprising a closure member arranged between said head part and said body a the interior thereof.
3 An ampulla syringe according to claim 1, wherein'said closure member is a thin disk and is-provided with a peripheral rib which is externally screw-threadedior'screw-threaded engagement with saidhead and is internally screw,-
threaded for screw-threaded engagement with said body.
