First Claim
1. An endoceliac physical quantity measuring apparatus comprising:
- 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 frequency characteristics of the vibrator;
a self-oscillating circuit for subjecting the vibrator to resonance vibration based on a detected vibration state of the vibrator;
load detecting means for detecting a load acting between the organic tissue and the contact;
arithmetic means for, when the load detected by the load detecting means reaches a predetermined threshold value, computing physical quantities of the organic tissue based on 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.
