Problems solved by technology

[0007] The problem with prior art rebound tonometers is that measurements (where the probe in the tonometer device moves in a tilted direction) cannot be made reliably because the probe tends to move from the device when it is tilted. drop

Embodiment Construction

[0035] Figure 1A A probe 3 is proposed that can be used in an embodiment of the device of the invention for measuring intraocular pressure, ie in a tonometer. The probe 3 is formed from a rear part 32 of magnetic material, such as steel, and a front part 31 of non-magnetic material, such as plastic material. The front part 31 of the probe 3 has a tip 4 which strikes the eye when measuring the intraocular pressure.

[0036] Figure 1B A probe 3 is proposed that can be used in an embodiment of the device of the invention for measuring intraocular pressure, ie in a tonometer. The probe 3 is partly a magnetic material, and the probe 3 has a tip 4 which hits the eye when measuring the intraocular pressure.

[0037] Figure 1C A first embodiment of the functional part 100 of the tonometer of the present invention is presented in which the Figure 1A with Figure 1B Probe 3.

[0038]The functional part 100 is located inside the tonometer housing together with other components b...

Abstract

The apparatus of the invention for measuring intraocular pressure comprises a functional part (100) with a tubular probe base (105) and a probe (3) contactable with a surface of an eye to derive an intraocular pressure in the eye from variations in a velocity of the probe (3). The probe (3) is inside the tubular probe base (105). The probe (3) is partly formed of magnetic material. An induction coil (101, 102) gives the probe (3) a specific velocity. The apparatus also has means for measuring the variations in a velocity of the probe (3), means for processing and displaying the measurement data, and controlling operations. The apparatus is mainly characterized by means (6) for holding the probe (3) inside the tubular probe base (105), and means for releasing the probe (3) for the measurement.

Description

technical field [0001] The present invention relates to devices for measuring intraocular pressure. The device includes a functional part having a tubular probe base and a probe contactable with the surface of the eye to derive intraocular pressure in the eye from changes in the speed of the probe inside the tubular probe base. The probe is partly a magnetic material. An induction coil imparts a specific velocity to the probe. The device also has means for measuring the speed change of the probe, means for processing and displaying the measurement data, controlling operation, means for holding the probe (3) inside the base of the tubular probe, and means for releasing probe to measure the device. Background technique [0002] Tonometry is a method for measuring intraocular pressure, and the device used for the measurement is called a tonometer. Various types of tonometers exist. In contact tonometry, there is physical contact with the cornea during the measurement. A p...
