Patented Nov. 3, 1931 UNITED STATES EUGENE WASSMER, or GENEVA, SWITZ R AND DEVICE FOR PERFORMING MEDIC AL' INJECTIONS Application filed October 17, 1927, Serial No. 226,751,an'c1 in,Switlzerland Qctober26,-1926.
This invention relates to a device for performing medical injections particularly adapted to inject a small gaseous mass into the organism.
I It is very important in certain medical treatments to inject gases into theorganism, particularly certain radioactive gases such as emanation of radium, called radon. But injections of this kind have to be made in very small quantities if the injected gas shall not produce any accident; for instance in intra-venous injections the gaseous embolia has to be feared, and the impossibility in the present state of art to inject sufliciently small quantities of curative gases did prevent the utilization of this treatment.
The object of the invention is to provide a device particularly adapted to inject very small quantities of a gaseous mess into the 0 organism. The invention consists of an injection apparatus which can receive in its interior a small hermetically closed and easily breakable capsula filled with gas, and means being provided to break this capsula from the exterior when it is in place in order that the gas when discharged from the capsula can be introduced into the organism by the injecting mechanism of the device.
The accompanying drawing illustrates by way of example an embodiment of the invention wherein the injecting mechanism is formed by a syringe.
1 is the cylinder of the syringe with the piston 2; 3 is a nozzle screwed in the head of the cylinder and provided with a stopcock of which the plug 4 shows the 'usual channel 5. A hollow plug 9 is screwed to the end of the nozzle adjacent the cylinder, while the free end of the nozzle is provided with a hollow plug 10 showing an interior shoulderupon which rests a strainer 6 with very fine meshes. 7 is a hollow cone held by friction in the plug 10' and keeping the strainer in place. A glass capsula 8 extends between the plug 9 and the cone 7 penetrating the channel 5 of the plug of the stopcock. This capsula has very small dimensions and is hermetically closed, containing a small quantity (from some tenth of a cubic millimeter to two or three cubic millimeters) of agas to be injected into the organism, for instance gaseous emanations of radlum, called radon.
In order to perform for instance an intravenous injection a needle is fastened to the end of the nozzle 3 and then the whole device is sterilized by a repeated aspiration and expulsion of alcohol; afterwards the same operation is repeated with a sterilized physiologic serum to remove all traces of alcohol; if the coagulation of'theblood is feared, one could take a solution of sodium cltrate lnstead of serum; then the needle is inserted in the vein chosen for the injection, the syringe being held in vertical or in such inclined position that the end of the needle constitutes the lowermost point of the injection device, and a quantity of from to 1 cubic millimeters of blood is aspirated into the syringe; then the stop-cock is closed and opened again by gently turning the plug 4 I while leaving the syringe perfectly immobile; the rotation of. the plug causes the cap- 7 sula 8 to break and to let the gas it contains escape; immediately after the breaking of the capsula the injection of the blood accumulated in the syringe is performed, but it is not necessary to inject the whole of the aspirated blood so that any air which will be present in the syringe will stay on top of the portion of blood which has not been injected. The strainer 6 prevents that the remains of the broken capsula get into the organism.
It is to be understood that the invention shall not be limited to the employ of blood for the injection; other injection liquids could be used. The capsula itself is susceptible to contain an inertor non-inert gas, an
inert or non-inert auxiliary therapeutic substance for the gaseous injection.
What I claim is:
1. A device of the character described, having an injection mechanism comprising a syringe, a nozzle carried by said syringe, a stop-cock on said nozzle provided with a rotatable plug, a channel formed in said plug, and a capsula penetrating said channel and extending beyond the length of the channel in both directions, said capsula being adapted to be broken when placed in the open stop-cock by turning said plug.
2. A device of the character described, having an injection mechanism comprising a syringe, a nozzle carried by said syringe, a stop-cock on said nozzle provided with a rotatable plug, a channel formed in said plug, a capsula penetrating said channel and out wardly projecting from it, and a strainer provided with fine meshes placedat the out.- let of said syringe to prevent the remains of the broken capsula from getting into the; V
organism.
