  • Publication number: 20080108956
    Abstract: An improved luer lock receiving septum having a configuration which provides rapid and tight resealing and yet allows penetration of the septum by the luer tip with a low penetration force. The elongated septum includes an upper portion of enlarged diameter having a target surface, a central slit, and a central, lower septum extension projecting about the slit below the upper portion and into a housing so that following luer insertion there is provided sufficient room for both the laterally displaced extension of the septum, the luer taper, and the housing to be received into a conventional luer lock connector. The septum is further preferably configured to minimize or eliminate the negative pressure deflection normally associated with the withdrawal of the large diameter luer cannula from an enclosed fluid filled lumen or chamber, by substantially isolating the lumen or chamber from the septum material displacement resultant from luer insertion.

  • Publication number: 20070238914
    Abstract: An electromagnetic cardiac assembly adapted to assist ventricular output in a human heart includes a magnetic mat adapted for mounting inside a human body near the heart. The mat is made from a material responsive to application of an electromagnetic field so as to be movable into compressive relation with the heart in response to application of the electromagnetic field thereto and movable out of said compressive relation to permit the heart to relax when application of the electromagnetic field is discontinued. The assembly also includes an electromagnetic subassembly adapted for mounting on the human body in functionally cooperative relation with respect to the mat, and an energy dispersion device adapted for mounting between the mat and the heart. The energy dispersion device is constructed and arranged to disperse energy between the mat and the heart.

  • Publication number: 20070225660
    Abstract: A medical swab pouch is disclosed. The inexpensive elastic pouch contains disinfectant and is configured for protecting and swabbing a wide variety of luer systems to prevent and eliminate bacterial contamination. The pouch has a flattened configuration and can be elastically dilated, as by squeezing the pouch between the thumb and index finger and is readily carried in large numbers in nurse's pockets (in a manner similar to that for conventional alcohol swabs). The pouch covers and protects the luer valve at the discretion of the user and without transmission of torsion or longitudinal force which might loosen the luer valve or otherwise be transmitted to the vein.

  • Publication number: 20070225635
    Abstract: A patient safety enhancing connection system and method for focusing the mechanical force of the fingers through a cannula to burst and/or wipe off bacteria to thereby mechanically reduce the number of microorganism at the connection interface. The system includes elastomeric septum which is under flow able compression having outer slitted septum face and configured to receive blunt cannula by penetration of the blunt cannula into the compressed septum. The septum face and the distal opening of the cannula are matched such that the edge of the inner wall of the cannula does not engage the septum face during the penetration process to minimize the potential transfer of microorganisms to the interior of the cannula, so that bacteria, if transferred, are preferentially transferred to the outer wall of the cannula where they are compressed, sheared or wiped off by the compressed elastomere and therefore do not reach the bloodstream.

  • Publication number: 20070149860
    Abstract: A system and method for organization and analysis of complex and dynamically interactive time series is disclosed. One example comprises a processor based system for relational analysis of physiologic signals for providing early recognition of catastrophic and pathologic events such as pathophysiologic divergence. The processor is programmed to identify pathophysiologic divergence of at least one of first and second physiologic parameters in relationship to the other and to output an indication of the divergence. An object-based method of iterative relational processing waveform fragments in the time domain is described wherein each more complex waveform object inherits the characteristics of the waveform objects from which it is derived. The first physiologic parameter can be the amplitude and frequency of the variation in chest wall impedance or nasal pressure and the second parameter can be a measure or indication of the arterial oxygen saturation.
