  • Patent number: 12017011
    Abstract: The intravenous catheter device (100) includes a catheter hub (102), a valve member (158), an actuator member (176) and a valve closure member (192). The valve member (158) includes a convex portion (162) provided with slits (170) defining prongs (172). The slits (170) are configured to open when a needle (116) is pierced through the slit (170) to puncture a vein of a patient. The valve closure member (192) is disposed inside the catheter hub (102) such that the first surface (194) of the valve closure member (192) abuts the convex portion (162) of the valve member (158). When the luer lock member (206) abutting the actuator member (176) inside the catheter hub (102) is disengaged, the valve closure member (192) is adapted to push the prongs (172), closing the passage (204) for the fluid flow and preventing blood flow from the punctured vein of the patient.

The proximal case portion includes an axially-extending boss that projects distally, with a portion of a distal end of the boss contacting the flow control valve. The valve permits fluid flowing in a distal direction to pass through the slit. Fluid flowing in a proximal direction, however, causes the valve to compresses against the boss and the slit to close, thus restricting fluid flow in a proximal direction.

  • Patent number: 8500717
    Abstract: The present invention relates to a connection piece for an enteral transfer system and to an enteral transfer system with such a connection piece, and also to an arrangement composed of such a transfer system and of an enteral feed probe. The connection piece according to the present invention comprises a distal attachment piece for attachment of a connection piece of a probe tube of an enteral feed probe, and a proximal attachment piece for attachment of the connection tube of a transfer system. The distal attachment piece of the connection piece is conical or is designed in stepped fashion with several portions of different diameter. The distal attachment piece can therefore be releasably connected to the funnel-shaped connection pieces of different diameter of the probe tubes of the known feed probes. The connection piece according to the present invention can be used universally in this respect.

  • Patent number: 8449528
    Abstract: A connector for coupling to a base of an indwelling device equipped with a circular hub having a radius, a top surface, a side surface, and a circumferential recess defined in the side surface. The connector has a resilient assembly including a plurality of release buttons extending from the resilient assembly and may include a conduit defining a fluid pathway through the connector. Each release button has a finger contact zone and a catch. The catch is configured to releasably engage the circumferential recess. The connector is coupled by positioning the connector on the circular hub and depressing the connector until the catches engage the circumferential recess such that the connector is configured to rotate completely about the circular hub. The connector is decoupled from the hub by pressing the release buttons to reversibly displace the respective catches radially to disengage from the circumferential recess.

  • Publication number: 20130085381
    Abstract: An infusion catheter assembly has the ability to infinitely titrate the length of a porous fluid distribution section in situ. The infusion catheter assembly thereby provides a length of infusion that can be infinitely varied over a prescribed range, to control the effective infusion length and the rate of infusion. Using the infusion catheter assembly, a physician has the capability to treat only the length of the vessel desired, thereby preventing excessive drug/patient exposures. The porous fluid distribution section can include an array of spaced apart apertures that vary in size and/or density along the length of the porous fluid distribution section, such that the flow rate remains essentially constant for a given inlet pressure independent of the effective infusion length.
