Abstract: A portable device for infusion of liquid drugs contained in a pair of syringes into a patient's body is disclosed. Said device includes a body housing a driving system and arranged to receive a pair of interchangeable syringes, and said driving system includes a single electric motor and a first and a second mechanical assembly, or a single mechanical assembly, each assembly being associated with one of the syringes or with both syringes, respectively, and being arranged to convert the rotary motion of the motor into a linear motion and to apply said linear motion to a pusher associated with the plunger of the respective syringe, both mechanical assemblies, or the single mechanical assembly, being operated for simultaneously causing the forward motion of the plunger in one syringe and the backward motion of the plunger in a second syringe.

Abstract: A portable pump for infusing liquid substances into a body is provided. The pump has a casing and electromechanical members for converting rotary motion of a motor shaft into linear sliding motion of a pusher for causing movement of a plunger slideable within an interchangeable reservoir in which the substance to be infused is contained in a housing. The housing communicates through an opening formed in a casing wall through which the reservoir can be inserted into and removed from the housing and from which an appendix of the reservoir protrudes for the exit of the substance. The housing has a distal portion with mechanical means for reversible engagement of the reservoir end opposite to the appendix and a proximal portion provided with an annular sealing gasket which surrounds the reservoir and forms a seal between the reservoir and casing wall.

Abstract: Tank (11) for a drug infusion device (41), comprising a hollow cylindrical body (13) provided at its front with an opening (15) for the passage of the drug and in its inside with a plunger (25) slidable within the tank for drawing in and/or injecting the drug through said opening, said tank being provided at its rear with a coupling part for ensuring the mechanical connection of the tank (11) with a complementary coupling part provided in the infusion device (41), said coupling parts defining together a bayonet-like connection coupling, said coupling part of the tank (11) being housed inside the cylindrical body (13).

Abstract: A plunger (13) for a syringe (11), comprising a cylindrical hollow body having a closed base and an opening located at the opposite base of said hollow body, wherein a seat accessible through said opening is provided to receive the head of a rod or a pusher (15), said seat being equipped with engagement means for retaining said head inside the seat at the end of an axial translational or an axial translational and rotary coupling movement. The application further concerns the rod intended to be associated with said plunger and a syringe or a phial using the plunger.
