Title (EN) METHOD AND APPARATUS FOR COMPENSATING FOR INJECTION MEDIA VISCOSITY IN A PRESSURIZED DRUG INJECTION SYSTEM
(FR) PROCÉDÉ ET APPAREIL DE COMPENSATION DE LA VISCOSITÉ DE MILIEUX D'INJECTION DANS UN SYSTÈME D'INJECTION DE MÉDICAMENT PRESSURISÉ
Abstract:
(EN) A needleless injection system is provided to deliver therapeutic fluids to an internal treatment site in a patient, where the system is pressurized and is capable of compensating for differences in injection media viscosity and mechanical system characteristics. In one aspect, a needleless therapeutic fluid injection system is provided that includes modular, interchangeable components. In particular, the system includes a console that generally includes the electronic and/or hydraulic control components for the system, an injection chamber, and a shaft or catheter tube.
(FR) La présente invention concerne un système d'injection sans aiguille destiné à délivrer des fluides thérapeutiques à un site de traitement interne chez un patient, le système étant pressurisé et capable de compenser les différences de viscosité de milieux d'injection et de caractéristiques de système mécanique. Dans un aspect, un système d'injection de fluide thérapeutique sans aiguille est fourni qui comprend des composants interchangeables et modulaires. Le système comprend en particulier une console qui comprend généralement les composants de commande électronique et/ou hydraulique du système, une chambre d'injection et une tige ou un tube de cathéter.
