Method of and apparatus for measuring vital tissue
First Claim
1. A method of measuring a vital substance in a vital tissue, the method comprisingfixing a periphery of a portion of a vital tissue to be measured to spatially fix the portion to be measured;
- contacting a measuring probe with the portion to be measured under a constant pressure from only a horizontal direction; and
measuring a vital substance in the vital tissue using the measuring probe.

Abstract
A fixture is provided on a set probe and a hole of the set probe communicates with that of the fixture so that a measuring probe consisting of an optical fiber bundle is inserted in the holes. A measured object is irradiated with light from a forward end of the measuring probe, so that outgoing light from the measured object enters the measuring probe. An air pack for coming into contact with the measured object is provided on the forward end of the measuring probe in a position not hindering emission and incidence of light. The air pack is connected with a pressure sensor, so that an indicator reads the pressure. Pressing force of the measuring probe is so adjusted that the pressure is at a constant value which is set for each measured object

2. A measuring apparatus suitable for measuring a vital substance in a vital tissue, the apparatus comprising
a set probe which is configured to contact a periphery of a portion of a vital tissue to be measured while excluding contacting the portion to be measured, to spatially fix the portion to be measured; -
a measuring probe which is movably disposed in and reversibly fixable to the set probe, wherein the measuring probe is configured to contact with the portion to be measured from only a horizontal direction; and a fixture for reversibly fixing the measuring probe to the set probe. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
