PRESSURE MEASURING METHOD, PRESSURE MEASURING DEVICE, AND TONOMETER

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.
