Endoceliac physical quantity measuring apparatus having excellent measuring resolution

摘要

An endoceliac physical quantity measuring apparatus comprises a contact adapted to touch an organic tissue, a vibrator connected mechanically to the contact, a frequency characteristic detecting circuit for detecting parameters associated with the frequency characteristics of the vibrator, load detecting means for detecting a load acting between the organic tissue and the contact, arithmetic means for computing physical quantities of the organic tissue on the basis of the parameters associated with the frequency characteristics detected by the frequency characteristic detecting circuit and the load detected by the load detecting means, and presentation means for presenting the physical quantities computed by the arithmetic means.
