Abstract
A cannula has an electrically conductive material that runs along the cannula. This material has an electrical terminal, which can be wired or wirelessly connected with a measuring device. This makes it possible to acquire the position of the cannula in a human body, and generate a warning signal given a dislocation of the cannula.
Claims16
A cannula with an electrically conductive material that runs along the cannula,
- wherein the material has an electrical terminal;
- wherein the cannula has an outer jacket and an inner jacket, which are electrically insulating, and between which the electrically conductive material is arranged such that the electrically conductive material is guided in a cannula wall and radially outwardly and radially inwardly insulated by a tubular wall;
- wherein the electrically conductive material extends in the cannula wall over an area along the cannula from the cannula tip to the electrical terminal;
- and
- wherein the cannula is adapted such that, when arranged in a body vessel, the outer jacket of the cannula acts as a dielectric, with the electrically conductive material corresponding to a first electrode, and the body vessel to a second electrode, such that the position of the cannula inside of a body part relative to an electrical contact surface can be measured.
