Abstract:
1. A programmable needle-less injection device, comprising: a nozzle comprising a nozzle head with a fluid input hole and an injection hole, the nozzle head accepts a dose of a fluid from the fluid input hole to be injected into skin of a patient through the injection hole, without penetrating the skin with a needle; a fluid capsule that is connected to said nozzle head; wherein said fluid capsule provides the nozzle head with multiple doses of fluid for successive injections, without replacing the fluid capsule; an injection head for mounting said fluid capsule and said nozzle head onto it, comprising a first mechanism adapted to forcefully push the dose of a programmable amount of fluid from said fluid capsule to said nozzle head and a second mechanism for injecting by a programmable pressure the dose from said nozzle head into the skin of the patient in at least one of a programmable velocity or the programmable pressure applied to a surface of the skin of the patient, wherein said nozzle head and said fluid capsule being independent from said injection head and being disposable; and wherein the disposable nozzle head includes a plunger that seals between the nozzle head and the second mechanism; and wherein the plunger is adapted to be moved up and down by the second mechanism to enable reception of multiple doses of fluid into the nozzle head and to inject them through the injection hole by the plunger.
