Abstract

"INJETOR SEM AGULHA COM PRESSURIZAçãO A GáS MODULAR". A presente invenção refere-se a um injetor sem agulha adequado para injeção de fluido através de uma superfície que inclui um alojamento, um acionador, um motor e um gatilho. O alojamento contém um fluido e o motor contém um gás comprimido. Mediante aplicação de força suficiente ao gatilho, o gás comprimido é liberado do motor forçando o acionador através do interior do alojamento, expelindo o líquido do alojamento a uma velocidade suficiente para perfurar a superfície de injeção. Em uma modalidade, o injetor sem agulha inclui um mecanismo para mitigar o coice associado à liberação do gás comprimido do motor. Em outra modalidade, o alojamento inclui apoios para dedos que fornecem estabilidade e resistência para ativar o dispositivo. Em outra modalidade, um prendedor de segurança é incluído no alojamento, impedindo a ativação acidental do dispositivo."NEEDLE NEEDLE GUN PRESSURIZING INJECTOR". The present invention relates to a needleless injector suitable for injecting fluid through a surface including a housing, a driver, a motor and a trigger. The housing contains a fluid and the engine contains a compressed gas. By applying sufficient force to the trigger, compressed gas is released from the engine by forcing the actuator through the interior of the housing, expelling the liquid from the housing at a speed sufficient to pierce the injection surface. In one embodiment, the needleless injector includes a mechanism for mitigating recoil associated with the release of compressed gas from the engine. In another embodiment, the housing includes finger rests that provide stability and resistance to activate the device. In another embodiment, a safety clip is included in the housing, preventing accidental activation of the device.
