1. Pulse oximetry sensor with fiber optic signal transmission comprising:

  • a light emitting and light detecting part (1a, 1b) containing light emitting diodes (11,

         12) with emission in at least two wavelength regions and at least a photo detector (13) with electric connection (2) via one or several connectors (3) to a pulse oximetry instrument (4), in which said light emitting diodes (11,

         12) and photo detector (13) are optically connected to one end of at least one fiber optic cable (7) to the other end of which is connected to a two-halved clamp (8,

         9) for fixation and transillumination of a finger, an extremity or other transilluminable body organ, andat least one power distributor (23) transferring a part of the available electric power from said pulse oximetry instrument (4) via said electric connection (2) to at least one power receiver (24), supplying at least one signal amplifier (25) with electric power.
