    Abstract: The present invention provides a low-cost, low-power therapeutic hypothermia device for use in developing nations. The device includes a first and second receptacle separated by a space filled with a porous material such as sand. A cooling chemical can also be added to the porous material in order to speed cooling. Water is added to the porous material and a neonate is placed into the device for therapeutic hypothermia treatment. The neonate is monitored carefully using temperature sensors and a feedback system integrated into the device. Cooling can be modulated and/or warming commenced by adding Styrofoam blocks to raise the neonate off the surface of the device.

  • Publication number: 20150011929
    Abstract: A device and method of the present invention provides application of low-energy acoustic waves to indwelling surfaces of a catheter in order to remove and prevent microbial biofilm formation. The low-energy acoustic waves are generated by an electrically activated piezo element. The device can take the form of a luer connector configured to couple to the hub of the indwelling catheter or can take the form of a catheter insert. The characteristics of the acoustic waves can be varied in order to inhibit bacterial adhesion to the indwelling surfaces of the catheter. Moreover, the characteristics of the acoustic waves must also be in a range so as to not induce bacterial adhesion to the indwelling catheter surfaces.

  • Publication number: 20140128792
    Abstract: An embodiment in accordance with the present invention provides a device and method for hemodialysis including a needle access port having a housing defining a septum, wherein the septum is configured for needle access. Generally, the needle access port will have three septa for communication with valves configured to be anastomosed to a large-diameter blood vessel. The valves are in fluid communication with a flow of blood through the large-diameter blood vessel. The device also includes an elongate tube having a first and a second elongate lumen, wherein a first end of the tube is coupled to the needle access port and a second end of the tube is coupled to the valve. The device can be cleaned by injecting a cleaning fluid into a first septum of the needle access port and extracting it though the second septum of the needle access port.

  • Patent number: 8571663
    Abstract: Featured is an apparatus an apparatus including a monitoring and sensing means, an electrode patch and a control device operably coupled to each of the sensing means and the electrodes and outputs signals to the electrodes for purposes of stimulating the phrenic nerve to thereby cause breathing by natural contraction of the diaphragm. The control device is configured and arranged to initially localize the phrenic nerve with respect to a given set of electrodes that is effective, when appropriately energized, for stimulating the phrenic nerve to establish negative pressure induced respiration in the body, based on the output signal(s) from the monitoring and sensing means. After such initially localizing; the control device thereafter repetitively outputs stimulation signals via the given set of electrodes so as to thereby continuously stimulate negative pressure induced respiration. Also featured are methods related thereto.
