  • Publication number: 20170165419
    Abstract: A medical delivery device is provided for delivering a medicinal substance into a user's body. A foldable hub has a left wing and a right wing, where the hub is attached at one end to a tube, and at an opposite end to a needle. At least one first rib is disposed on the left wing and at least one second rib is disposed on the right wing. When the wings are folded back away from the needle and pinched together, the first and second ribs prevent twisting and/or sliding of the wings relative to each other during an insertion of the needle into a user's skin, thereby preventing a breakage of the needle due to undesirable movement of the wings.

  • Publication number: 20170120009
    Abstract: An IV catheter system may have a catheter component and a needle component. The catheter component may have a catheter hub, a cannula extending distally from the catheter hub, and a push feature extending outward from the catheter hub. The push feature may have an outer surface that receives contact from a digit to move the IV catheter system from an insertion configuration, in which the needle is within the cannula, to a fluid delivery configuration, in which the needle is outside the catheter hub. The needle component may have a needle hub and a needle extending distally from the needle hub along an axis. The push feature may be formed of a flexible material that causes the push feature, in response to pressure exerted on the outer surface by a dressing securing the catheter component to a patient, to deflect the outer surface toward the cannula axis.

  • Patent number: 8085301
    Abstract: Techniques are disclosed relating to gas leak detection. The techniques can be deployed, for example, in compact, handheld portable devices usable for detecting leaks in space-confined applications. The devices generally include an unstablized laser and thermal imaging camera that allow for detection of gas that absorbs at least some of the wavelength of operation of the unstablized laser. The devices can be operated at a low-power density for safety and/or may be configured to mitigate wavelength hopping associated with unstablized laser light sources.

  • Patent number: 7882970
    Abstract: An anesthetic container includes a bottle having a wall defining a receptacle and a neck with a passage in fluid communication with the receptacle, a valve assembly including a flange, and a ferrule disposed over at least a portion of the flange of the valve assembly and about at least a portion of the neck of the bottle to secure the valve assembly to the bottle. One of the wall of the bottle, the flange of the valve assembly or a wall of the ferrule has at least one vent formed, at least in part, therein that permits air trapped between the ferrule and the valve assembly or the bottle to escape.

  • Patent number: 7826455
    Abstract: A method for providing single point-of-presence for a network element includes receiving a packet at a network processor, determining if the packet is to be directed to a particular one of a plurality of traffic processors if a source address of the packet is associated with a subscriber terminal, and determining if the packet is to be directed to the particular one of the plurality of traffic processors if a destination address of the packet is associated with the subscriber terminal. The method further includes distributing the packet to the particular one of the plurality of traffic processors.

  • Patent number: 7675851
    Abstract: An apparatus for communicating data is provided that includes a cell site element associated with a base transceiver station and comprising a compression module that is operable to receive a plurality of bits associated with a communications flow, to inspect the bits, to determine whether one or more samples included in the flow should be suppressed, and to compress the samples. The cell site element is coupled to a back-up device that is operable to assume responsibility for active flows in a case where a primary device fails. Data is exchanged between the primary device and the back-up device, the data guiding the back-up device in how to process the active flows.

  • Patent number: 7046663
    Abstract: In a pipeline network processor, a packet intercept feature determines whether a packet is to be intercepted based on the inbound and outbound port through which the packet travels and based on the source and destination of the packet. When a packet enters the pipeline network processor, a determination is made as to whether the inbound and outbound ports are enabled for packet intercept. If so, a source and/or destination media access control address is compared to a list of configured intercept addresses. If a match is found, a copy of the packet is diverted to an intercept receiver and the original packet is forwarded to its intended destination.

  • Patent number: 6912785
    Abstract: A notebook computer has a base housing with a heat-generating microprocessor therein, and a lid housing pivotally connected to the base housing. Operating heat from the microprocessor is transferred to the lid housing, for dissipation therefrom, via a specially designed thermosyphoning heat pipe structure formed from first and second heat pipes. The first heat pipe representatively has a rectangular cross-section, an evaporating portion thermally communicated with the microprocessor, and a coiled condensing portion centered about the lid hinge line and having a circularly cross-sectioned interior side surface portion defined by flat sides of the first heat pipe. The second heat pipe has a circular cross-section, an evaporating portion pivotally received within the coiled first heat pipe portion, and a condensing portion thermally communicated with the lid housing.

  • Patent number: 6608714
    Abstract: A thermal actuator includes a first arm having a proximal end and a distal end, a second arm, parallel to the first arm, having a proximal end and a distal end, and a third arm arranged between and parallel to the first and second arms, the third arm having a proximal end and a distal end. The third arm has at least one portion at the distal end of the third arm having a width that is substantially larger than a width of the first arm and a width of the second arm. The distal ends of the first, second and third arms are coupled together to form a distal end of the thermal actuator, and the first, second and third arms preferably are made of a single material. A number of thermal actuators can be arranged in an array. The thermal actuator or array of thermal actuators can be coupled to an applicator.
