Abstract: A manually operated mechanical pump for drug infusion through a syringe including a plunger slidable within a syringe body to cause drug contained within the syringe body to exit a front opening of the syringe. The pump has a pump body with an open front end, to which the syringe attaches, and an open rear end, at which a drive member is associated movably relative to the pump body. A pair of thrust members are provided between the drive member and the syringe to impart longitudinal thrust in a distal direction onto the plunger to cause the drug to exit the front opening. An elastic element is provided between the thrust members to store and release elastic energy when the first thrust member proximal to the drive member is manually actuated, thus causing the second thrust member proximal to the syringe to advance as the drug exits the front opening.

Abstract: Portable pump (11) for drug infusion through a syringe (SR) removably engaged in the pump, said pump comprising an electromechanical unit (13) having a rod (15) which is longitudinally slidable within a guide member (17) and capable of exerting an axial thrust onto the plunger (SF) of the syringe engaged in the pump, wherein said rod (15) and said guide member (17) have a non-circular cross-section, whereby rotation of the rod (15) relative to the guide member (17) is prevented.

Abstract: A syringe actuating device has a first supporting plate in which an axial guide for a primary rod is defined and a second supporting plate defining at least two engagement seats for bases of corresponding syringes having a barrel and a sliding plunger. A guide for axial sliding of a corresponding secondary rod with a head is associated with each of the engagement seats. The device also includes an electric motor having a driving shaft, an assembly for converting rotary motion of the shaft into translational motion of the primary rod and a pair of connecting arms adapted to transmit sliding motion of the primary rod to a corresponding one of the secondary rods. Rotary movement of the driving shaft causes sliding of the secondary rods and, consequently, sliding of the plungers when the syringes are engaged in corresponding engagement seats and the plungers are in abutment against the heads.

Abstract: Shell (11) for a portable electromechanical apparatus for drug infusion, comprising an outer casing (13) and a support structure (15) housed within the casing (13), wherein said casing (13) has a monolithic ring shape and is entirely made of plastics, and wherein said support structure (15) is at least partially made of metal.

Abstract: A device for filling and priming syringes is provided and comprises a support base, an engagement seat defined on the support base to receive a rear end of a syringe barrel of a syringe provided with a sliding plunger, engaging means defined at the engagement seat to cooperate with the syringe barrel for firmly holding the syringe to the engagement seat, a first vacuum pump or compressor which is provided with a suction opening communicating with the engagement seat to generate an under-pressure in the volume comprised between the plunger and the engagement seat when the syringe is firmly engaged in the engagement seat, and a second vacuum pump or compressor which is provided with a discharge opening communicating with the engagement seat to generate an over-pressure in the volume comprised between the plunger and the engagement seat when the syringe is thinly engaged in the engagement seat.

Abstract: A safety quick-refill compact pump for administering drugs is provided. The pump includes a motor-driven electromechanical actuator, a cylindrical container, and a hollow piercing element. The actuator causes bi-directional axial sliding of a rod that carries a pusher adapted to cause axial sliding of a plunger of the container which contains a liquid drug and is equipped, at an end thereof, with a pierceable membrane. The actuator is provided with a first connecting portion of a male-female connecting joint at least partially surrounding the rod. The container is provided with a second connecting portion of the male-female connecting joint and is firmly associated with the actuator and defines a cylindrical chamber axially extending about the sliding axis of the rod. The piercing element is oriented toward the inside of the chamber and defines a duct so that the piercing element is in fluid communication with the inside of the reservoir.

Abstract: A device for filling and priming syringes is provided and comprises a support base, an engagement seat defined on the support base to receive a rear end of a syringe barrel of a syringe provided with a sliding plunger, engaging means defined at the engagement seat to cooperate with the syringe barrel for firmly holding the syringe to the engagement seat, a first vacuum pump or compressor which is provided with a suction opening communicating with the engagement seat to generate an under-pressure in the volume comprised between the plunger and the engagement seat when the syringe is firmly engaged in the engagement seat, and a second vacuum pump or compressor which is provided with a discharge opening communicating with the engagement seat to generate an over-pressure in the volume comprised between the plunger and the engagement seat when the syringe is thinly engaged in the engagement seat.

Abstract: An arrangement for connecting a syringe to an electromechanical pump for drug infusion is provided. The syringe comprises a syringe body having a first end for discharging a drug and a second end connected to the pump in a removable manner. An axially sliding plunger is housed in the syringe body for causing suction and injection of the drug through the first end. The pump comprises a pump body having a sliding rod that causes sliding of the plunger within the syringe body. The pump body has a collar axially extending around the sliding rod and provided with engaging elements. The syringe body has engaging elements arranged to cooperate with the engaging elements of the collar for firmly connecting the syringe to the pump. An annular flange extends radially around the syringe body. The flange cooperates with the collar to establish a tight sealing between the syringe body and the collar.
