  • Patent number: 8398575
    Abstract: An early warning and shutdown system that connects to a fluid loss detection device for dressings at pre-existing port sites, catheter sites, operative sites, ostomy sites, drain sites, line sites such as those utilized in hemodialysis, wound sites, or other areas for which monitoring of fluid or blood loss is medically indicated. The early warning and shutdown system sounds an alarm when the fluid loss detection device senses a loss of fluid, and then compresses a return tube carrying such fluid to stop further fluid loss if the fluid loss continues.

  • Patent number: 8235930
    Abstract: A fluid loss detection device for dressings at pre-existing port sites, catheter sites, operative sites, ostomy sites, drain sites, line sites such as those utilized in hemodialysis, wound sites, or other areas for which monitoring of fluid or blood loss is medically indicated. The detection device includes a patch having a primary loop circuit and an early warning alarm circuit loop. In one embodiment, closure of the early warning alarm circuit loop activates an alarm. The alarm may be connected directly to the patch and sound locally or may be activated remotely via radio transmission. The alarm may alternatively cause a medical device such as a hemodialysis system to shut down.

  • Patent number: 7641612
    Abstract: A blood loss detection device for a hemodialysis system having a blood intake line, a dialysis machine including a pump, with the dialysis machine in communication with the blood intake line, and a blood return line in communication with the dialysis machine. The detection device includes a patch having an exterior edge and an opening through the patch forming a target for receipt of the return blood line. A slit through the patch extends between the exterior edge and the opening. A primary loop circuit terminates at two ends at the slit. An early warning alarm circuit loop terminates at two ends at the slit. An emergency shut-down circuit loop terminates at two ends at the slit. A modular connector connects the patch to an alarm activated by the early warning alarm circuit and to a switch mechanism activated by the shut-down circuit in order to shut down the dialysis machine and the pump.
