Abstract: A millifluidic device for cultures of biological agents comprising: a main body (11) comprising at least a first hole (40) closed at the bottom; a separator (35); a membrane (36) fixed to said separator (35); a plug (15) closing said first hole (40); said separator (35) designed to be placed in said first hole (40); said separator (35) being extractable from said first hole (40); said membrane (36) divides said first hole (40 ) into an upper half-chamber and a lower half-chamber; a pair of tubes (25) to perfuse said lower half-chamber; a pair of tubes (26) to perfuse said upper half-chamber; a first slide (22) placed centrally on said plug (15); a second slide (42) placed centrally on said first hole (40); a cylindrical body (41) rises from said first hole (40) and said second slide (42) is placed on the top of said cylindrical body (41); said cylindrical body (41) has a second hole (43), coaxial to said cylindrical body (41).

Abstract: A medical device for percutaneous or venous access is provided with an internal cavity, from which a cannula extends in a first position of work. The cannula is supported by a distal end of a cannula-holder which is able to move within the cavity under the action of a resilient thrust element to a second position of work. Actuation means associated with the body of the device are provided to permit this movement and cooperate with actuation counter-means integral with the cannula-holder. In at least one of the two positions of work, the cannula has its longitudinal axis (W) disposed inclined relative to the longitudinal axis (K) of the tubular body.

Abstract: A safety catheter needle having a cannula removably inserted in a catheter and associated with a cannula holder is provided. The cannula has a proximal extremity attached to the cannula holder and a distal extremity close to a deformed part, with provision for a protection device associated with the catheter holder movably containing the cannula and moving within the catheter holder when the cannula is drawn out from the catheter. The protection device has a principal body containing a moving body rotating about an axis (M) at right angles to a longitudinal axis (W) of the cannula and capable of interacting with a fixed part of the catheter holder—while the cannula is being drawn out, bringing about rotation of the rotating moving body within the principal body and immobilizing the distal extremity of the cannula within the former.

Abstract: A device for cell culture comprising: a main body (11); said main body (11) comprises a plurality of circular portions (21-23); said device comprises a plurality of caps (51-53); each of said plurality of caps (51-53) comprises a base structure (58) having a circular hole (57), housing an upper slide (54) and an elastomeric layer (56) secured to said slide (54); said elastomeric layer (56) has a rectangular hole (59); said plurality of caps (51-53) being adapted to cooperate with said plurality of circular portions (21-23); each of said plurality of circular portions (21-23) each comprise an inlet hole (64-66) and an outlet hole (67-69) aligned with the long side of said rectangular hole (59), to perfuse the culture chamber (12-14) located in said rectangular hole (59) of said elastomeric layer (56).

Abstract: A safety needle having a rigid outer structure within which there is a cannula holding element of being movably coupled to an injector pen for a drug is provided. The cannula holding element supports a cannula having a first extremity and a second extremity for administration of the drug. A moving protective element associated with the rigid structure, covers the second extremity of the cannula after administration, with provision being made for a deforming member capable of deforming the cannula after administration of the drug so that the second extremity of the cannula remains within the protective element. The deforming member is associated with the protective element and is capable of rotating autonomously with respect thereto after administration of the drug to deform the cannula.

Abstract: A medical device for percutaneous or venous access for the purposes of administering a fluid to a patient or sampling from one is disclosed. The device includes a cannula holder that has a part or portion of cross-section which is reduced or different from its distal end and proximal end. The part or portion of reduced or different cross-section allows the cannula holder to deform within the body of the device when activating means are activated to separate the cannula holder from an immobilising member allowing the cannula holder to move in the body of the device and re-enter and disappear within such body of the cannula.
