Device for measuring the depth of penetration and low selectivity of flow probes in human or animal tissue and use of these

摘要

A selective depth measurement device has two equal sidewalls (2), rear (3) and front (4) walls, a base (5) and a hollow space. The sidewalls and the rear wall have a greater thickness than the front wall so that sensors can be applied. Numerous stacked flexible tubes pass through the walls and a hollow space surrounded by walls of an optically translucent material and filled with a testing substance. There is a supporting surface for setting up a flow probe on a top edge.
