发明名称 PORTABLE INTRAOCULAR PRESSURE MEASUREMENT METHOD AND APPARATUS
摘要 <p>A device for continuously monitoring intraocular pressure includes a contact lens (11) having a pressure transducer (17), including at least one semiconductor strain gauge crystal (33) fixed to a membrane on lens (11), and fit with the sclera. A projection (27) for scleral indentation is positioned to transmit response to intraocular pressure to the crystal (33). A memory unit is mounted in the lens in non-scleral contact for recording measurements. A tonometer (11') for monitoring intraocular pressure through the sclera has a frame forming a handle which includes a pressure transducer (13') having sleeve (17') mounting it on an axis along which a spring (19') positions it in response to pressure applied byurging the probe against the sclera. The device (11') includes a conductive ring (21') on the sleeve (17') and electrical contacts on the axis to complete a circuit to generate a signal when within a zone of measurement which has predetermined upper and lower limits of pressure.</p>
