摘要： The present invention relates to a device for creating a vascular access for extracorporeal blood treatment including an electrically conductive puncture needle with a proximal endpiece, a distal endpiece, and a base body made of electrically non-conductive material into which the distal endpiece is inserted. In a properly arranged vascular access, the base body, including an electrically conductive contact element, lies on the skin of the patient, when the puncture needle is located within the vessel of the patient. A disconnection or dislocation is detected by the impedance between the electrically conductive puncture needle and the electrically conductive contact element being measured and compared to a limit value. If the impedance measured is within predetermined limits, this indicates a properly arranged vascular access. A disconnection or dislocation of the puncture needle leads to a strong variation in the impedance.

摘要： The present invention relates to a device for creating a vascular access for extracorporeal blood treatment using an extracorporeal blood treatment device, wherein the device for creating the vascular access has an electrically conductive puncture needle with a proximal endpiece and distal endpiece, and a base body that is made of electrically non-conductive material and into which the distal endpiece of the puncture needle is inserted. In the case of a properly arranged vascular access, the base body, which includes an electrically conductive contact element, lies on the skin of the patient, when the puncture needle is located within the vessel of the patient. A disconnection or dislocation is detected by the impedance between the electrically conductive puncture needle and the electrically conductive contact element being measured and compared to a limit value. If the impedance measured is within predetermined limits, this indicates a properly arranged vascular access. A disconnection or dislocation of the puncture needle leads to a strong variation in the impedance, which indicates that the vascular access is not properly arranged.
