摘要： A noncontact type tonometer projects a fluid toward an eye-to-be-tested and obtains a measured value of eye pressure from a relation between transfigurations of the eye due to the fluid projection and the pressure projecting the fluid. A detecting circuit senses a pulse wave of the person-to-be-tested and a calculating circuit determines at least one of the maximum eye pressure value, minimum eye pressure value and average eye pressure value of the eye dependent on the maximum fluctuation width of the detected pulse wave, a fluctuating quantity of the detected pulse wave, and the measured eye pressure value. The calculation circuit determines the pulse wave fluctuating quantity at the time point when the eye pressure is measured. The pulse wave of the person may be measured at a position remote from the eye. The tonometer may also include a display for displaying the pulse wave and a display controller for displaying the time point when the eye pressure is measured. The displayed eye pressure overlaps the displayed pulse wave to illustrate the relation between the measured eye pressure value and the pulse wave fluctuation.

摘要： A surgical cutting instrument which comprises an outer tubular member having a closed distal end closed and also having an aperture defined therein adjacent to the closed distal end which is in communication with the hollow of the outer tubular member and an inner tubular member having an open distal end which is slidably disposed in the outer tubular member such that the inner tubular member slides along its longitudinal axis first and second positions. The distal end of the inner tube has also has a scraper region defined therein. The scraper region is curled so as to represent a curved shape corresponding to a portion of a circle having a diameter greater than the outer diameter of the inner tubular member, so that when the inner tubular member is moved within the outer tubular member, the curled scraper region can be forcibly brought into sliding contact with an inner peripheral surface of the outer tubular member. Therefore, during the movement of the inner tubular member from the first position towards the second position relative to the outer tubular member, the curled scraper region is moved past the aperture in the outer tubular member to cut a tissue entering into the outer tubular member through the aperture.
