INJECTION DEVICE AND METHOD FOR GENERATING A FLUID JET The injection device (10) according to the invention comprises a fluid applicator (11) which is fed by a fluid dispensing assembly (12), said dispensing assembly. of fluid containing an energy storage device (29). Preferably, the latter will be configured as the pressure vessel (36). The gas pressure derived from this pressure vessel (36) will act either directly (figure 5) or indirectly (figures 3, 4) on a vessel previously filled with ejection fluid (eg isotonic NaCi solution). The fluid to be ejected is then subjected to constant pressure. By means of a valve (23), the user can start ejecting the desired amount of fluid with constant intensity. Check valve 23 may also be a regulating valve which may be used by the user to vary the intensity of the effect. The invention basically presents the implementation of an always available injection device capable of being produced highly cost-effectively. The user only needs to release the system, such as by punching the pressure vessel (36), in order to be able to directly inject the fluid in a defined or measurable manner through the probe, ie the fluid applicator (11). ). Handling, releasing and actuating the check valve or regulating valve (23) is made easy and intuitive. However, it will also be possible to configure the entire injection device (10) as a disposable system, and pre-fill the fluid applicator (11) to its respective fluid outlet opening. A sterile seal at the distal end of the fluid applicator (12) may be provided through a protective cap (16).DISPOSITIVO DE INJEÇÃO E MÉTODO PARA GERAR UM JATO DE FLUIDO O dispositivo de injeção (10) de acordo com a invenção compreende um aplicador de fluido (11) que é alimentado por um conjunto de dispensa de fluido (12), o referido conjunto de dispensa de fluido contendo um dispositivo de armazenamento de energia (29) .
