catheter for measuring blood flow through body tissue and device for measuring blood flow through body tissue

摘要

catheter for measuring blood flow through a body tissue, catheter head for insertion into a body tissue and device for measuring blood flow through a body tissue a device for measuring the blood flow of a tissue of the body comprising a catheter having a catheter head (1) for insertion into a body tissue and a centerpiece (3) having a light emitting surface (17), outside of which an optical conductor for conducting light , and having a reflection surface (18), which is arranged in opposition to the light emitting surface (17) and oriented obliquely to the longitudinal geometric axis of the optical conductor. the optical conductor is arranged so that the emitted light rays are directed at the reflection surface (18), the emitted light rays can be deflected on the reflection surface (18) and reflected within the body tissue, and a ray of light reflected can be reflected off the body tissue on the reflection surface (18) and supply the optical conductor. the catheter head is divided into an insertion region and a connection region, where the insertion region comprises a plurality of recesses (5) on the surface thereof. towards the connection region, the insertion region has an increased diameter. the recesses (5) are provided in the insertion region so that a network (11) is formed in the direction of the connection region between the recesses along the surface of the catheter head.
