Abstract: A hose consisting of a smooth tubular wall and a rib wound spirally on the smooth tubular wall. The hose includes at least one duct portion and at least one connection portion; in the connection portions, the rib is wound spirally with a narrower pitch than on the duct portions.

Abstract: A system for transtracheal administration of supplemental oxygen to a patient in need of continuous long tem oxygen therapy comprising a cannula (1), a transtracheal catheter (3) and an absorbing preformed disk (30), placed under a fixing flange (11) in order to absorb possible secretions.

Abstract: A die for molding a cuff on a plastic tube, including an upper shell and a lower shell defining a molding cavity between them; each of the shells has an external structure and an internal wall for defining a half of the molding cavity and for defining a hollow space with the external structure. The molding cavity and hollow spaces are separated from each other by internal walls. The die includes openings which are connected with the molding cavity and the hollow spaces respectively.

Abstract: Method for manufacturing a cuff on a plastic tube comprising an inner tube and an outer sheath covering said inner tube. The outer sheath comprises at least a portion to be molded for producing a cuff. The method comprises a covering step including an injection operation in which air is intermittently or continuously injected between the inner tube and sheath.

Abstract: An apparatus for manufacturing extruded coiled tubes for medical purposes is provided which includes rotary shafts protruding from a spindle, each rotary shaft being coupled to a respective flexible shaft resting on a series of supporting elements substantially equidistant to each other and supported by a main central shaft; at least an extrusion head to extrude a ribbon, and at least an extrusion head to extrude a rib; the ribbon and the rib being co-extruded, side by side, and being wound on an ideal surface formed by the external surfaces of the flexible shafts. The apparatus is characterized in that for changing the pitch with which the rib is wound on a base tubular element, formed on its turn by the winding coil of the ribbon, at least two twisting bars operated by a crank are used to rotate the supporting elements with a pre-defined angle.

Abstract: An anti-condensation arrangement for catheters including a heated air generator, a sheath covering a catheter such as to create a cavity with it, and a device for the input of heated air produced by the generator into the cavity wherein the sheath has a venting opening to allow the exit of heated air from the cavity and therefore continuous exchange of air.

Abstract: An anti-condensation arrangement (5) for catheters comprising a heated air generator (6), a sheath (9) covering a catheter (4) such as to create a cavity (I) with it, and a device (7,8) for the input of heated air produced by the generator (6) into the cavity (I). The sheath (9) has a venting opening (9b) to allow the exit of heated air from the cavity (I) and therefore continuous exchange of air.

Abstract: A respiratory gas conditioning system and method are provided and includes an inhale branch (IB), an exhale branch (EB), a low-dead-space heat and moisture exchanger (HME), and a connector (70) for connecting the branches (IB, EB) to a patient (PZ) wherein the HME is located close to a ventilator; and a water reservoir (RS) is located upstream from the HME to moisture-enrich the gas exhaled by the patient (PZ) as it flows along the exhale branch (EB).

Abstract: An HME (heat and moisture exchanger) (10) having a septum (or filter) (15) formed by pleating a sheet (150) of material capable of retaining and releasing heat and moisture. The HME (10) is characterized in that walls (15a, 15b, 15c) of the septum (or filter) (15) are coated partly or completely with sealing material to define at least two exposed areas (A1, A2) through which inhaled gas (F1) and exhaled gas (F2) flow respectively. Moreover, each sheet (150) of material is divided into identical units (150a) “fan-folded”, in use, one on top of another to form a first set of passages (150b) through which only the inhaled gas (F1) flows, and a second set of passages (150c) through which only the exhaled gas (F2) flows.

Abstract: The hygroscopic cartridge (1) particularly for filters for medical use, has a band-like element (2) which is wound to form a flat bobbin (7). The band-like element (2) has a first band (3), formed with corrugations (4) which extend in a transverse direction with respect to the longitudinal extension of the band-like element (2) and made of a heat-conducting plastically deformable material, and a second layer (5) impregnated with hygroscopic salts. The corrugations (4) define small channels (8) for allowing the passage of an aeriform flow in a transverse direction with respect to the plane of lay of the flat bobbin (7).
