  • Patent number: 10285846
    Abstract: Disclosed herein is a urethral catheter with an anti-infection structure for infants in which, in a state in which a hose is combined with a main pipe in advance, the reinforcement rod is inserted into/released from a urethral insertion pipe through a reinforcement rod inflow and outflow pipe separately formed at one side of the main pipe to prevent leakage of urine. When the reinforcement rod is inserted into the urethral insertion pipe in the combined state of the hose with the urethral insertion pipe and is then released from the urethral insertion pipe, setting of a urine storage bag is completed, thereby shortening a time to install of the urine storage bag, reducing medical staff's trouble, and preventing contamination and infection of a patient and the medical staff due to leakage of urine from the bag to the outside.

When IOP exceeds a critical valve, a practitioner intervenes, puncturing with a laser a thinned region of the tube lying outside the eye, thereby initiating drainage of fluid and relieving pressure. In accordance with alternative embodiments, the both ends of the tube are open, and the tube includes a one-way valve configured to permit drainage where IOP exceeds the critical value. The tube may include projecting barbs to anchor the tube in the eye without the need for sutures.

  • Patent number: 8992489
    Abstract: A fluid delivery system which includes a pressurizing device for delivering injection fluid under pressure, a low pressure fluid delivery system, and a pressure isolation mechanism. The pressure isolation mechanism includes a valve housing having a first port associated with the pressurizing device, a second port associated with the low pressure fluid delivery system, an outlet port associated with a patient, and a pressure isolation port for connection with a pressure transducer. A first valve in a normally open position permits fluid communication between the first port and the second port and is movable to a closed position when fluid pressure in the first port increases to a predetermined pressure level. The first valve isolates the pressure isolation port from the first port when in the closed position. A second valve is associated with the second port and regulates fluid flow through the second port.

  • Patent number: 8986262
    Abstract: A sampling connector for use in sampling a body fluid such as arterial blood or cerebrospinal fluid. The sampling connector comprises at least two apertures in fluid communication via a fluid flow conduit and a one-way valve (14) disposed to allow fluid flow from the first aperture, through the fluid flow conduit and out of the second aperture, but not to allow fluid to flow into the second aperture and through the fluid flow conduit to the first aperture. In use, the sampling connector is connected to a body cavity to enable the sampling of a body fluid by withdrawal of the body fluid through the first aperture, and to prevent the introduction of a separate fluid to the body cavity. The first aperture can be within a male end and the second aperture can be within a female end or vice versa. A sampling device comprising a sampling connector according to the present invention and use of the sampling connector and/or sampling device is also claimed.

  • Publication number: 20150045747
    Abstract: A valved container assembly which has a container for containing a fluid, the container extending in an axial direction and having an open front end and a valve disposed in the container. The valved container assembly is configured so that forward axial movement of the valve relative to the container is inhibited. A plunger element is disposed axially rearward of the valve and is axially moveable in the container. The plunger element is configured to increase the pressure of a fluid in a first volume of the container upon forward axial movement relative to the valve. The valve includes a channel bypassing the permanent seal, the channel having a first opening in fluid communication with the atmosphere outside of the valved container assembly and a second opening selectively sealed from the first volume by a resilient seal.

  • Patent number: 8951229
    Abstract: A catheter includes a pressure actuated seal within a manifold. A catheter body is coupled with the manifold, and a manifold lumen and a catheter lumen are configured to receive pressurized fluids. The pressure actuated seal includes a pressure actuated seal element having a seal element lumen. The seal element lumen is in communication with the manifold and catheter lumens. The pressure actuated seal element is deformable between an open configuration and a sealed configuration. In the sealed configuration, the pressurized fluids in the manifold press on the pressure actuated seal element along a first seal face. The pressure actuated seal element compresses inwardly around the seal element lumen according to a pressure of the pressurized fluids. In the open configuration, the pressure actuated seal element relaxes in an absence of the pressurized fluids, and the seal element lumen is open and configured to allow passage of an instrument.

  • Publication number: 20150005717
    Abstract: 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.
