Device for visually indicating a blood pressure

摘要

The invention relates to an indicator device for visually indicating a pressure of blood inside a blood vessel (8). It comprises a body (3, 10) in which a duct (14; 14') extends. The duct (14; 14') has a sealed proximal end, and the distal end portion of the body (3, 10) is adapted to be positioned inside the blood vessel (8). There is provided at the distal end of the body (3, 10), a liquid inlet opening (11) in fluid communication (6) with the duct (14; 14'). A window in the form of an at least semi-transparent section (20) is provided in the body, for enabling visual observation of blood (23) entering into the duct (14; 14') via the inlet opening (11), when the inlet opening (11) is located inside the blood vessel.
