MEDICAL APPLIANCE FOR EXTRACORPOREAL BLOOD TREATMENT
The medical appliance has lines (22, 23) that are connected to the vascular system of a patient. To ensure that an accidental escape of blood is identified, a camera (17) is provided and is directed at the extracorporeal circulation of the patient. The image signals from the camera (17) are processed in the sense that the colour of blood and/or its arrangement in the image area in the camera image is determined, wherein the size of the recorded image area with the colour of blood is also determined. In this way, an extracorporeal blood loss can be detected and signalled automatically.
