Abstract: There is provided a flexible, helically wound conduit for a breathing circuit. The conduit includes an inlet, an outlet, and an enclosing wall defining a flow passage between the inlet and the outlet, wherein at least a region of the enclosing wall is permeable to water vapor and one or more of O2 and CO2. The axial tensile strength of the enclosing wall is greater than 40N. Further provided are limbs comprising the conduit, a method of manufacturing the conduit and the use of the conduit to remove water vapor and/or CO2 from gas exhaled by a patient.

Abstract: The invention relates to a profile made from a polymer material comprising a linear low-density polyethylene and a very low-density polyethylene having a specific range of flexural modulus, and to a flexible hose made from said profile. It is part of the invention that the profile wall thickness of the flexible hose is reduced while a sufficient and efficacious value for the flex life is maintained and while a sufficiently high memory is maintained, when compared to the common wall thickness of current hoses, such that the hose of the invention has a reduced weight while the durability and fatigue resistance of the hose is maintained at a sufficiently high value.

Abstract: A hose storage system and method for an electric hose for use in a central vacuum system comprising a hose storage area and a vacuum inlet valve. The system has a manual switch which can independently activate the vacuum system to create suction in the hose storage area to retract the hose and is covered when the hose is stored. The hose comprises a first end with a hose cuff for connection to the vacuum connection opening of the inlet valve, and, a second end with a wand connection for connection to a wand or other electric device. During storage, the switch is operated to activate the vacuum system generating a vacuum in the storage area and retracting the second end of the hose into the hose storage area while the hose cuff is connected to the vacuum inlet opening.

Abstract: Disclosed is a flexible plastic hose (1) comprising a tubular hose body (2) having web portions (7) and a helical reinforcing rib (8), and a cuff (3a) mounted to an extremity (16) of the hose body (2) comprising a molded end fitting (5a) bonded to the extremity (16a), and a stress relief element (4) with a first segment (S1) having an internal screw-thread (15) complementary to the helical reinforcing rib (8). Disclosed is also a method for making same, and use of the hose (1) as a medical hose.

Abstract: A breathing circuit system for supplying a breathable gas from a breathable gas supply system to a patient interface. The system comprises a heated conduit, comprising a hose and a hose heating system associated with the hose, and a plurality of adapter elements. The hose heating system is provided for operating within a first predetermined voltage range. A controller is associated with the breathing circuit and provides voltage within a second predetermined voltage range. Each adapter element comprises at least one electric component provided for adjusting the voltage supplied by the controller from a second range to the first range.

Abstract: Flexible plastic hose comprising a flexible wall made out of a plurality of laterally connected windings of a helically wound profile, wherein the windings of the profile are attached to each other by means of a weld, wherein the profile comprises a web part with predetermined properties for providing flexibility to the hose, and wherein the profile ends on both sides in an upright part. The weld is located between the upright part of the adjacent windings and together with these upright parts forms a helical reinforcement rib on the flexible wall of the hose with predetermined properties for providing hub strength to the hose.

Abstract: A modular respiratory system to which different parts can be added in a convenient way enabling such upgraded respiratory system to deliver the most comfortable respiratory conditions at an acceptable cost of ownership.

Abstract: A flexible stretch hose with a wall which comprises a spirally wound profile (1; 11; 21) in a plastic material. Consecutive windings of the profile are secured to each other by means of a weld. The profile comprises, in cross-section, at least one bottom section (2; 12) and at least one rib section (4; 14; 24), wherein the rib section of the profile, relative to the bottom section, also forms a protrusion of the wall of the hose which gives the hose a predetermined hub strength. The profile comprises an unfoldable section (5; 15; 25) provided in order to be unfolded under the influence of a tensile; force in the axial direction of the hose, thereby allowing an extension of the hose, wherein the unfoldable section comprises at least two profile sections lying loosely against each other, which sections are interconnected at one end.
