Abstract: An automatic fluid injection device having an upper body (1) with an injection system (3, 4, 5) controlled by a power supply (7) and that is triggered by a user interface (100); and an insertion mechanism (8, 9) for inserting an injection needle (110); a base body (2) for coming into contact with an injection zone and having a fluid reservoir (6) containing an injection piston (65), and a needle assembly (10) including the injection needle (110). The injection system has an elongated spring metal strip (3) wound on a respective reel (30) before actuation; and a drive mechanism (5) for unwinding the strip (3) against a respective piston (65) so as to perform the injection, and for rewinding the strip (3) on the reel (30) after injection.

Abstract: An automatic fluid injection device having a body fastened to a support for coming into contact with an injection zone, the body containing one or more fluid reservoirs each containing an injection piston; a needle assembly including an injection needle for penetrating into the injection zone; and an injection mechanism. The injection mechanism having an actuator cap containing an expandable material, and a heater mechanism for heating the expandable material, thus causing it to expand so as to move the piston in the reservoir, and thus inject the fluid into the injection zone through the injection needle. The expandable material has thermally expandable microspheres.

Abstract: An automatic fluid injection device comprising: a base body (1) for coming into contact with an injection zone; a support assembly (2) for supporting an actuator mechanism (5, 6, 7) that is controlled by power supply means (11); at least one fluid reservoir (3), each containing an injection piston (35), arranged in said base body (1); a needle assembly (100) comprising an insertion actuator (8), needle movement means (9, 9′), a priming needle (101) for associating with each reservoir (3) and for penetrating into said reservoir (3) before moving its piston (35), and an injection needle (102) for penetrating into the injection zone and for injecting the contents of said reservoir(s) (3) into said injection zone, said device including at least one actuator button (200) for priming, inserting the injection needle into the injection zone, administering fluid, and then retracting the injection needle.
