Medical measuring device

A method for the collection and evaluation of physiological parameters, the method comprising:

• providing a measuring device comprising at least one optical measuring unit generating at least one of oximetric measuring signals and plethysmographic measuring signals, and an evaluation unit for processing the measuring signals, wherein the evaluation unit is designed such that at least one local metabolism parameter is determined from the signals furnished by the at least one optical measuring unit,
• wherein the optical measuring unit has at least two radiation sources for irradiating the body tissue to be examined, and at least one radiation sensor for the detection of at least one of the radiation scattered by the body tissue and the radiation transmitted by the body tissue,
• wherein the at least two radiation sources have different spatial radiation characteristics comprising different beam angles, and
• wherein the at least two radiation sources irradiate different volume areas of the body tissue to be examined,
• collecting the at least one of measuring signals selected from the group consisting of oximetric measuring signals and plethysmographic measuring signals from body tissue via the optical measuring unit
• and processing the at least one of measuring signals via the evaluation unit for the purpose of determining at least one of the pulse and the local oxygen concentration,
• wherein
• via the evaluation unit at least one local metabolic parameter is determined.
