  • Patent number: 10881847
    Abstract: A neutral pressure split-septum luer access device is described for receiving a luer lock connector. The septum has a plurality of elastomeric columns projecting laterally within a chamber. Each elastomeric column is under sufficient compression so that the columns are bowed and the column strength is reduced by bowing, but the slit sealing force is high. This configuration places the lower portion of the slit in a tightly sealed configuration which is never-the-less receptive to penetration by the male luer which causes the columns to bow further and collapse precipitously with the elastomeric force of the collapsing mass of the columns being carried distally to displace and pop open the central slit distal the tip of the male luer. The septum further provides a transverse separation between the columns and a distal sealing portion so the force of the displacement force to the sealing portion is reduced.

  • Patent number: 9169934
    Abstract: A method for switching a high pressure fluid includes applying a fixed force between a planar surface of a rotor and a planar surface of a stator. The planar surface of the rotor includes a fluidic channel and the planar surface of the stator has a pair of ports to receive and provide the fluid. A control signal is applied to a linear actuator coupled to the rotor to generate a controllable force between the planar surfaces of the rotor and stator. The control signal is responsive to a rotational state of the rotor. The total force between the planar surfaces of the rotor and the stator is substantially equal to a sum of the fixed force and the controllable force. The method reduces the wear and extends the lifetime of components in a rotary shear seal valve.

  • Publication number: 20100133457
    Abstract: The invention relates to a coaxial coupling which comprises a male part (501) and a female part (502) and comprises a bypass valve (218) so that the female part (502) can be decoupled from the male part (501) while pressurized fluid passes through the female part (502). The nipple pipe (105) of the male part (501) pushes a spring-loaded valve (218) in the female part (502) over said rear holes (301) in the inner pipe (2) of the female part. The female part (502) has a rotatable locking sleeve (207), which is coupled to a sleeve (214) accommodating pins (213).

  • Publication number: 20100044609
    Abstract: A pipe connector is provided with a valve cartridge. The pipe connector can be modified so as to meet requirements for a variety of uses without changing the basic design of the connector body by simply replacing the valve cartridge with another valve cartridge having valve functions meeting a desired use. The pipe connector includes a tubular connector body 10 through which a fluid flows, and a valve cartridge 30 capable of being fitted in the connector body and of controlling the flow of the fluid.

  • Patent number: 7588562
    Abstract: A fluid collection apparatus is provided that includes a housing configured for receipt of fluid and/or tissue for collecting fluid therefrom. A holder is configured with the housing to receive an evacuated tube. The holder can include a needle hub supporting a needle cannula in fluid communication with a port extending into a fluid well of the housing. A sloped bottom surface of the housing directs fluid to the fluid well. A sidewall extension or support component extends downward beyond the sloped bottom surface to allow the housing to be stood upright on a flat surface. In certain embodiments, the apparatus includes a tubular cavity to provide a recessed location of the needle cannula for preventing accidental needle injuries. An optional cap provides further shielding from needle cannula and safely maintains fluid in housing after use.

  • Publication number: 20080258092
    Abstract: A valve assembly is provided having two valve sections, each having a tubular passageway portion and when joined together, defining a ball cavity in communication with the tubular passageways. One of the body sections is provided with an inlet/outlet in communication with the ball cavity as well as a spindle flange. An elongate spindle extends through the spindle flange projecting into the ball cavity region to rotate a spherical ball element between an open and a bypass position. The ball valve has a primary elongate passage which interconnects the two tubular passage portions in the valve body sections when the ball valve is in the open position. When the ball valve is rotated to the bypass position, the tubular passage portion of one of the ball body sections is sealed closed while the other tubular passage portion communicates with an internal bypass port within the ball valve which in turn, communicates with the auxiliary inlet/outlet.

  • Publication number: 20080111092
    Abstract: Valve unit with a sliding throttle-chamber, comprising a valve body with an exchange or distribution chamber adapted to receive a sliding throttle-chamber of which the position of translation in the chamber defines ways of fluid communication between a primary inlet opening and at least two secondary outlet openings that can be selectively blocked or released by said throttle-chamber; the sliding throttle-chamber has a composite structure and consists of a first part controlling the fluid communication of said, at least, one secondary or radial outlet opening with the chamber and a second part controlling the fluid communication of the secondary or axial outlet opening with the chamber, the two parts of the throttle-chamber being linked together by a driving link in translation with a dead or non-driving area between the two extreme translation positions of said throttle-chamber.

  • Publication number: 20080097407
    Abstract: A luer activated device includes an inlet adapted to receive a male luer, an outlet associable with a fluid flow system, and a flow path defined therebetween. The inlet receives a resealable valve element having a aperture adapted to receive the male luer. The valve element is compressible, such that a male luer inserted into the aperture will cause the valve element to primarily compress, rather than stretching and deforming. One end of the aperture may include a pressure activated flow passage, which is adapted to open upon fluid flow through a male luer received by the aperture. Methods of using such luer activated devices are also provided.

  • Patent number: 7350536
    Abstract: A portable receptacle is vacuumized for use in taking an air or gas sample for subsequent examination to determine type, origin, components of the air or gas. Critical to a long shelf life of the vacuumized receptacle is a valve which virtually seals the receptacle for months or years permitting storage of the receptacle in a state ready for immediate use at a site. The valve utilizes a positionable member plated with a noble metal. A filter serves to collect particulate from the air or gas flow into the receptacle. A funnel shaped collector aids in the collection.

  • Patent number: 7314061
    Abstract: Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves comprising a stretched body. In one aspect of the present invention, a plug is positioned inside a slip port. When the plug is pushed by a medical implement and moves to a second position, the plug abuts the valve body and stretches the valve body. When the medical implement is subsequently removed, the stretched body forces the plug back to its first position.

  • Publication number: 20070235673
    Abstract: The invention comprises a low cost method of sealing and resealing a microfluidic device before, during, and after communication of fluids into the microfluidic device. The invention includes a microfluidic device with fluid introduction ports substantially hermetically sealed with elastomeric plugs, wherein the plugs can be penetrated by hollow needles to introduce fluids such as air, water, ethanol, or other chemical or biological reagents into the device while maintaining a substantially hermetic seal. The invention includes a method for introducing fluids into a microfluidic device from an external source. The method comprises the steps of penetrating fluid introduction ports substantially hermetically sealed with elastomeric plugs with hollow needles connected to a fluid source, pumping fluid into the device, and removing the hollow needle from the plug, whereupon plug self-reseals to form a substantially hermetic seal.
