摘要:
The invention relates to a fluid storage device including a container (1), comprising a valve (2) and a cap (3). The device comprises a split mounting ring (4), that is, a mounting ring having a single opening (14) on the circumference thereof and provided for installing/removing the mounting ring on/from the container (1). The opening (14) of the ring (4) is provided so as to form, during installation or removal of the ring (4), a passage for one portion or section of the container, or one member mounted onto the container. The cap (3), in the unmounted position thereof, includes at least two portions that are movable relative to each other. In the mounted position, said portions of the cap (3) are secured to each other and clamp the ring (4) onto the container (1). The mounting ring (4) is made up of molded or injected plastic material, and the opening of the mounting ring (14) is obtained by removing a breakable portion (24) of the ring which is molded or injected (14) at the same time as the rest of the ring (4).

The invention concerns a bypass device for a fluid circuit, in particular a gas circuit (4, 8) for circulating fluid comprising two separate sections (4, 8) for circulating fluid provided each with an upstream end and a downstream end, the upstream end of each fluid circulating section (4, 8) being capable of being in fluid communication with a fluid input port (E) of a circuit, the downstream end of each section (4, 8) being capable of being in fluid communication with a fluid output port (S) of a circuit. The invention is characterized in that each circulating section (4, 8) is mounted mobile relative to a fixed base (1, 6) between a first position in which the upstream and downstream ends of said section (4, 8) are in fluid communication with respectively the fluid input port (E) and output port (S), and a second retracted position in which the upstream and downstream ends (4, 8) of said circulating section (4, 8) are not in fluid communication respectively with the fluid input port (E) and output port (S), the two circulating sections (4, 8) being connected by a movement coupling element relative to the base (1, 6) between a first working position in which the upstream and downstream ends of a first section (8) are in fluid communication with respectively the fluid input port (E) and output port (S), and a second bypass position in which the upstream and downstream ends of the second section (4) are in fluid communication with respectively the fluid input port (E) and output port (S), the two sections (4, 8) are arranged relatively to the base (1, 6) such that, between the working position and the bypass position, the two sections (4, 8) pass through at least one intermediate position in which the upstream ends of the two sections (4, 8) are simultaneously in fluid communication with the fluid output port (S), to provide a bypass for the fluid of one section towards the other without interrupting the fluid flow between the input port (E) and the output port (S).

The invention concerns a venturi device (1) for delivering oxygen or an air/oxygen mixture comprising a main body (10) with an inner compartment (11) and a venturi nozzle (20); a rear member (30) with an oxygen inlet (31), air inlets (32) and a mixing chamber (33) for mixing oxygen and air. The rear member (30) is mobile with respect to the main body (10) between a closed position wherein the rear member (30) provides oxygen to the venturi nozzle (20), and an open position wherein the rear member (30) provides an air/oxygen mixture to the venturi nozzle (20). The rear member (30) is mobile at least in rotation with respect to the main body (10) for allowing a user to manually select a desired open or closed position, preferably according to a helicoidal motion. Installation (100) for providing oxygen or an air/oxygen mixture to a patient comprising a gas reservoir (101), a flexible hose (103), a respiratory interface (104), a connecting hollow body (102), and such a venturi device (1).

L'invention porte sur un procédé de fabrication d'un fil fourré (1) à partir d'une bande métallique (2) et d'un flux interne (3), comprenant les étapes de conformer (13) une bande métallique (2) en une gouttière de section en « U » par rapprochement de ses bords longitudinaux (4, 5) ; remplir (14) la gouttière obtenue avec un flux (3) ; conformer la gouttière remplie par le flux (3) pour obtenir un pré-tube de section en « O », et souder (15) au moyen d'un faisceau laser, les bords longitudinaux (4, 5) l'un avec l'autre. En outre, préalablement à la première étape de conformage, on opère un usinage (11) de la surface latérale (6,7) d'au moins l'un des deux bords (4, 5) de la bande métallique pour lui conférer une rugosité de surface inférieure à 50 µm. De plus, le rapprochement des bords (4, 5) longitudinaux s'effectue jusqu'à obtenir un espacement entre les surfaces latérales (6, 7) desdits bords longitudinaux inférieur à 50 µm, mesuré au point d'impact du faisceau laser. Fil fourré directement obtenu par le procédé de fabrication de l'invention.
