Abstract
Improvements introduced in the main patent no. 467.761 by system to ensure the controlled dosing of fluids of preferred clinical use, characterized by a volumetric device consisting of a rigid camera of revolution of achataed form, subdivided by a double elastic membrane in three elastic chambers whose sum of volumes is constant, the central chamber being hydraulically communicated with an external tank whose volume is adjustable so that due to the incompressibility of the inert liquid that fills it, it also controls the volume of the central elastic chamber and, with said device, regulates the sum of the volumes of the other two lateral chambers that can be varied from zero to a maximum volume slightly lower than that of the rigid chamber, both side elastic chambers being connected to the inlet and outlet ducts of the fluid through a four-way valve flow switch (q that happens, when making the commutation by an unstable position in which they close the four tracks) so that when entering the flow in any one of the elastic chambers press through the double diaphragm the liquid that occupies the other elastic chamber; forcing out of it a volume equal to that entering until the double diaphragm is compressed against the inner wall of the rigid chamber, giving the particular circumstance that every time the flow divider valve is switched off a dose whose volume is adjustable and equal to the sum of both elastic chambers.
