  • Publication number: 20100147312
    Abstract: A respiratory access assembly includes a distal plate having a port, which is adapted to be positioned in operable communication with an artificial airway of a patient. The assembly includes a distal plate having a port and a proximal plate which has a first port and a second port. The distal plate is positioned against the proximal plate in a stacked configuration, and each plate is configured to move relative to the other. The assembly has an actuator which is positioned adjacent to at least one plate. The actuator cooperates with both plates to substantially prevent movement of the plates when the port of the distal plate is positioned in an alignment with at least one port of the proximal plate and an object, such as a suction catheter, is positioned through the aligned ports of the plates. The actuator cooperates with at least one plate to permit movement of at least one plate when (a) no object is positioned through aligned ports, and (b) when no ports are aligned.

  • Publication number: 20100152706
    Abstract: An atraumatic suction catheter having a tubular body with a lumen formed therethrough. At a distal end, the catheter has three equally spaced elongated openings positioned near its distal tip. The catheter may have a fourth round opening positioned proximally to the three openings. The catheter has improved suctioning ability of viscous secretions, and reduced impact compared to other suction catheter embodiments.

  • Publication number: 20100147296
    Abstract: There is provided a port sealing cartridge that allows for insertion of a catheter or other medical device into an endotracheal tube and thence the patient's lungs through an available access port. The port sealing cartridge has a primary and a secondary seal or collar that sequentially provide a pressure seal as a medical device is inserted through them and into the system. An optional tethered dust cover may also be used on the proximal end of the port seal cartridge. The port seal cartridge may desirably be fitted with a quick-connection so that it may be easily removed, disposed of and replaced. The port seal may be used for access to a patient's lungs with a bronchoalveolar catheter, bronchoscope or other medical device for treatment or sampling of the respiratory tract.

  • Publication number: 20100147297
    Abstract: There is provided a novel fitting having male and female ends and a tapered internal luer-type seal. The male fitting end has a periphery upon which is mounted at least one boss. The female fitting end has a slot into which the boss may be inserted. At the bottom of the slot is a stop to limit the insertion depth of the boss. The male and female ends may then be rotated relative to each other to move the boss into a window on the female end. The window has a frame and the upper frame is angled slightly, corresponding to the boss, which serves to draw the male end farther in to the female end. The window has a side frame that stops the rotational movement of the boss. When the movement of the boss is stopped, the male and female tapers are in substantially leak-free contact. There is also provided a closed suction catheter using the novel fitting, such that the catheter may be easily and quickly removed and replaced.

  • Publication number: 20100147310
    Abstract: A respiratory access assembly includes a distal plate having one port and cuff and an axially aligned proximal plate including a first port and first cuff and a second port and second cuff. The distal plate is configured to move relative to the proximal plate. The respiratory access assembly includes an actuator, which has a plurality of predetermined positions. When the actuator is positioned in a movement-enabling position, it permits movement of the plates while simultaneously blocking the first port of the proximal plate. When the actuator is positioned in a first locked (open) position, it locks the plates together and aligns the port of the distal plate with the first port of the proximal plate and un-blocks the first port of the proximal plate so that an object, such as a suction catheter, may be positioned through the aligned ports.

  • Patent number: 7729890
    Abstract: A method of estimating a change of a variable over a measurement window, including the steps of taking multiple samples of the variable during the measurement window, defining a weight to be associated with each sample, the weight varying as a function of position of the sample within the measurement window, processing the samples taking account of their weight to form an estimate of the change in the variable.

  • Publication number: 20090077184
    Abstract: A remote operator and a mobile terminal initiate contact with a remote control proxy server. These components may be behind a firewall. If a mobile terminal does not have a then-extant session with the remote control proxy server, the remote operator and/or the remote control proxy server may send an SMS message to the mobile terminal and/or a device associated with the mobile terminal, which SMS message causes the mobile terminal to initiate a session with the remote control proxy server. After the mobile terminal and the remote operator are both connected to the remote control proxy server, the remote control proxy server passes communications between the mobile terminal and the remote operator without modification. The remote operator may control the mobile device keyboard, screen and may pass arguments to parameters associated with the operation of the device or its applications.

  • Publication number: 20070238381
    Abstract: A seaming system for forming a seam is disclosed, wherein the seam consists of at least two opposed sections of high-modulus, high-tenacity, low-elongation fabric sections joined by a tape. The system comprises a seamer head, and a seamer base that includes a topography configured to impart a predetermined pressure gradient to the adhesive layer, tape, and fabric sections of the seam. The resultant seam has a cross-section or thickness profile that generally corresponds to that of the applied pressure gradient. As such, the constructed seam more efficiently distributes stress imparted from any applied load.
