Abstract: A programmable injection device, comprising: a nozzle comprising a nozzle head with a fluid input hole and a distinct injection hole, the nozzle head accepts a dose of fluid from the fluid input hole to be injected into the skin of a patient through the injection hole, without use of a needle, a fluid capsule that is connected to said nozzle head and is adapted to provide the nozzle head with multiple doses of fluid for successive injections, without replacing the fluid capsule, an injection head that is adapted to have said fluid capsule and said nozzle head mounted onto it, comprising a first mechanism adapted to forcefully push a dose of a programmable amount of fluid from said fluid capsule to said nozzle head and a second mechanism for injecting by an programmable pressure said dose of fluid from said nozzle head into the skin of a patient in at least one of a programmable velocity or a programmable pressure applied to the skin surface.

Abstract: A needle-less fluid injection device, including, a nozzle head with an injection hole for accepting a dose of fluid to be injected into the skin of a patient, a fluid capsule that is connected to said nozzle head and provides the nozzle head with one or more doses of fluid for injection, an injection head for mounting the fluid capsule and the nozzle head; including a first mechanism for releasing a dose of fluid from the fluid capsule to the nozzle and a second mechanism for injecting the dose of fluid from the nozzle into the skin of a patient.
