    摘要: A device for delivering a liquid including a pump, and an anti-siphon valve external to the pump is disclosed. The anti-siphon valve includes an inlet channel connected to the outlet duct of the pump, and an outlet channel, between which a seat and a moving member are disposed that are suitable for co-operating together and that define, between the inlet channel and the outlet channel, a leaktight liquid flow zone. The moving member is suitable for going from an opening position making it possible for liquid to flow through the flow zone, to a closure position in which the moving member comes into contact with the seat of the valve and prevents any flow through the flow zone, the moving member being subjected to the pressure of a reference chamber that is not in fluid communication with the outlet channel.

    摘要: The invention concerns a flow regulator, made of a stack of 3 plates, respectively a top plate including a flexible membrane (1), a middle plate (2) with pillars and through holes and a bottom plate (3) with fluidic ports, micro channels and through holes (8,9,12). The principle is based on the deformation of the membrane due to the pressure of the liquid. The membrane goes in contact with the pillars of the middle plate, obstructing gradually the through holes of the pillars. The device is designed to keep the flow constant in a predefined range of pressure. The device is dedicated to ultra low flow rate up to 1 ml per day or below, typically for drug infusion. Plastic flow regulators comprise preferably several independent valves coupled in parallel. The membrane plate is therefore made of several flexible membranes obstructing gradually the flow by increasing the pressure. Stress limiters are used to avoid plastic deformation of the membrane. For implanted pump, the use of a flow regulator instead of a flow restrictor has several advantages, including the possibility to reduce significantly the reservoir pressure and to generate directly the pressure during the pump filling by using an elastic drug reservoir.

    摘要: A fluid flow regulator (1) of the passive type is disclosed which has a fluid inlet adapted to be connected to a fluid reservoir and a fluid outlet (13) adapted to be connected to a patient's body. The regulator comprises a rigid substrate (2) and a resilient membrane (3) tightly linked together so as to define a cavity (6) there between which is disconnected to the fluid outlet while the membrane has a first surface (12) opposite the cavity which is connected to the fluid inlet. The membrane has a plurality of through holes (15) contiguous with the cavity, to define a pathway for a fluid from the fluid inlet to the fluid outlet, and is flexible so as to be able to come into contact with the substrate as a fluid applies a sufficient pressure on the first surface. The through holes are arranged such that, when the fluid pressure increases, they close one after the other to increase the regulator fluidic resistance so that a fluid flow rate would be substantially constant as a function of the pressure applied on the first surface within a predefined pressure range.
