A system for injecting DNA-based medications into humans is provided by the present invention. The system includes a needle-free injector (10) with an injection orifice of approximately 0.004in for supplying DNA-based medication at an initial pressure of from 3900 to 4300 psi, and then immediately declining to a level of about 2800 to 3800 psi, and then immediately cutting off pressure to terminate the injection. The injector includes an annular adapter (12) for spacing the injection orifice from the skin of the patient. The adapter includes an abutment against (16) which the injector is disposed so that the orifice is spaced approximately 0.76-1.0in from the skin of the patient, the adapter having an inner diameter at the distal end of approximately 0.50-0.70 in.
On décrit un système d'injection de médications à base d'ADN chez l'homme. Le système comprend un injecteur (10) sans aiguille doté d'un orifice d'injection mesurant approximativement 0.004 pouce qui permet de distribuer une médication à base d'ADN à une pression initiale comprise entre 3900 et 4300 psi, puis à une pression secondaire qui décroît immédiatement à un niveau compris entre environ 2800 et 3800 psi, la pression étant ensuite immédiatement stoppée pour terminer l'injection. L'injecteur comprend un adaptateur annulaire (12) prévu pour éloigner l'orifice d'injection de la peau du patient. L'adaptateur comporte une butée (16) contre laquelle est placé l'injecteur de sorte que l'orifice soit espacé approximativement de 0,76 à 1,0 pouce de la peau du patient, l'adaptateur ayant un diamètre intérieur au niveau de son extrémité distale qui mesure approximativement de 0,50 à 0,70 pouce.
