摘要： A tonometry device includes a contact device for contacting the object, means for vibrating the contact device and the object, means for applying a voltage to the vibration means, means for measuring a current flowing through the vibration means, and an information processing means. The information processing means determines two resonance points of the device and the measured object by measuring current through the system at a plurality of vibrational frequencies. The information processing means then determines the internal pressure of the object by determining that a first pressure is higher than a second pressure by determining that the first pressure has a lower measured current than the second pressure at frequencies outside of the range of frequencies between the resonance points, and that the first pressure has a higher measured current than the second pressure at frequencies within the range of frequencies between the resonance points.

摘要： Provided are a pressure measuring method where a pressure is measured with a simple method and with high reproducibility and an intraocular pressure measuring device that is capable of measuring an intraocular pressure only by being made to come in contact with an eyelid and with which a subject himself/herself can perform intraocular pressure measurement. The intraocular pressure measuring device is constituted of a measurer (1), a piezo driver, a terminal base, an information processing device, and a resistor. The measurer (1) is constituted of a vibrator (11) such as a bimorph vibrator, four rubber bases (12), a case (13) vibratable with the vibrator (11) and the rubber bases (12) received in the case, and a contactor (14) coming in contact with an eyelid (16). In intraocular pressure measurement, the contactor (14) is made to come in contact with the eyelid (16). The vibrator (11) is constructed from a bimorph vibrator where an electric current varies according to the inner pressure of an object to be measured in contact with the vibrator with a contact AC voltage applied to the vibrator. A pressure such as an intraocular pressure of the object to be measured is measured by measuring an electric current value flowing in the vibrator.
