Publication number: 20210307632Abstract: The invention relates to a measuring device for continuously determining the intra-arterial blood pressure in a finger of a hand, the measuring device comprises a base part and a cuff part. A light source for near-infrared light and a photodetector are provided for the finger. The light sources and the photodetectors are connected to an associated optical emission surface or optical collector surface via a respective so-called light pipe for coupling emitted light into the finger tissue or decoupling non-absorbed light from the finger tissue. The cuff-side and base-part-side sections of the light pipes are connected to one another via separable optical contact points at the interface between the cuff part and the base part. On the base-part side, a cover glass closes flush with the housing of the base part and is attached to the contact points.Type: ApplicationFiled: August 27, 2019Publication date: October 7, 2021Inventors: Torsten SCHEUERMANN, Aaron WEBER, André HEIN, Thomas THALMEIER
