Description

Technical Field

[0001] This application belongs to the field of intraocular pressure measurement technology, and particularly relates to intraocular pressure measurement devices. Background Technology

[0002] Pressure within the human body is closely related to health. Blood pressure is the pressure of the blood itself, which is familiar to everyone. In addition, there are other body pressures such as pulmonary pressure, intracranial pressure, renal pressure, and intraocular pressure.

[0003] Intraocular pressure can be measured using external devices. Traditional tonometers use mechanical equipment to contact the eyeball for measurement, or they use air to blow into the eyeball and observe the deformation, which is very inconvenient for the test subject. The measuring devices are also bulky and difficult to make portable.

[0004] Intraocular pressure (IOP) is the pressure exerted by the eye's tissues on the eyeball wall. Normal IOP is between 10 and 21 mmHg; both excessively high and low IOP can affect eye function. For example, prolonged writing, watching television, or using a computer can cause eye fatigue and blurred vision. Closing the eyes briefly usually restores normal accommodation. However, if IOP increases irreversibly, glaucoma can occur, causing eye pain and swelling. Without timely treatment, it can lead to blindness.

[0005] Application number "2023100553102" entitled "Tissue Pressure and Tissue Moisture Content Measurement Device" discloses a device for measuring tissue pressure by means of signal absorption characteristics. This device can measure tissue pressure by utilizing the absorption characteristics of light signals in tissue. This application makes a portable tonometer possible.

[0006] In medicine, tissue pressure is generally measured relative to atmospheric pressure, such as blood pressure and intraocular pressure. When atmospheric pressure changes, the human body needs to make adaptive adjustments, and the absolute value of tissue pressure is constantly changing. Tissue pressure at different altitudes is also a relative value. When measuring tissue pressure using the absorption characteristics of light signals in tissues, the differences in environmental pressure must be taken into account.

[0007] Even in the same location, such as at low altitudes, the daily atmospheric pressure fluctuates between 0.75 and 3 mmHg. This can lead to significant measurement deviations in tissue pressure. For example, normal intraocular pressure in humans is 10 to 21 mmHg, with a normal daily fluctuation range of 8 mmHg. At low altitudes, atmospheric pressure fluctuations may range from 3 mmHg. Atmospheric pressure fluctuations account for more than 30% of the fluctuation range in intraocular pressure. Therefore, the influence of atmospheric pressure on tissue pressure measurement must be considered. Summary of the Invention
