Abstract: Loader-mixer device for endermic injectors which is suitable to cooperate with a portable endermic injector momentarily in loading, by aspiration through an injection-aspiration nozzle included in an injection head (17) of the portable endermic injector, the product to be injected, the device comprising in cooperation:at least one seating to lodge and position phials (12) together with two needles (13-14),a socket (31) to position the injection head (17), anda selector assembly (20) to connect a phial (12) to the injection head (17) as required.

Abstract: Portable endermic injector of a mechanical type which comprises an aspiration and containment chamber, an assembly (12) to aspirate and to store, a cocking and trigger assembly (13) and an assembly (14) to read the quantity aspirated. A containment assembly (11) comprises the aspiration and containment chamber and a piston (19) and is screwed onto a frontal container (15). The assembly (12) to aspirate and to store energy comprises apparatus to regulate the pre-loading of a spring assembly (28) which includes spacer rings (226) and apparatus (15-23) having variable axial reciprocal positions. The reader assembly (14) comprises a threaded portion (46) and a slider (47) cooperating with a graduated area (50).
