Abstract: Apparatuses, devices, systems and methods for detecting access disconnection during medical therapy are provided. The present invention includes an electric circuit coupled to, for example, a blood circuit used during dialysis therapy. The electric circuit can be adapted to inject an electrical signal into the blood circuit such that changes in an electrical value in response to access disconnection, such as needle dropout or catheter drop-out, can be effectively detected.

Abstract: Apparatuses, devices, systems and methods for detecting access disconnection are provided. The present invention includes electrical contacts in fluid and electrical communication with a fluid passing between a patient and a medical system during therapy. In this regard, the present invention can use a direct-contact measurement to detect access disconnection, such as dislodgment of an access device from the patient through which fluid can flow during therapy including, for example, medication delivery, dialysis therapy and the like.

Abstract: A device for guiding and gauging a hand-held power saw during crosscut operations on a workpiece. The device is comprised of a guide section and a gauge section interconnected by means of a length of wood strapping. The guide section has a sheath-like structure mounted on a rectangular plate with an upwardly directed forward flange and a downwardly directed side flange. The forward end of the wood strapping terminates in the guide's sheath-like structure. The forward flange guides the power saw across the front of the device. The side flange positions the device on the workpiece. The gauge section also has a sheath-like structure mounted on a square metal plate with a downwardly directed user side flange and a downwardly directed rear flange. The wood strapping passes through the gauge's sheath-like structure and is fixedly attached thereto. The flanges hold the device in position on and at one end of the workpiece.
