<p>The invention relates to those apparatus that include a disposable microsyringe, whose tubular body is attached by its rear end into the front starting point of a longitudinal void of an intermediate housing, locating in said longitudinal void a moving head movable upon an axis and, which is connected to the rear end of the syringe plunger. It is characterised in that the moving head (9) is also connected, by means of a longitudinal rod (12), to a moving carriage (13) movable upon an axis along the same direction as the moving head (9), and being said moving carriage (13) guided within an elongated tube (8) connected to at the rear end of the intermediate housing (7), as a continuation thereof, incorporating to said elongated tube (8) a motor element, whose actuation drives the plunger (10) by means of a moving head (9), a longitudinal rod (12) and a moving carriage (13).</p> |
