Description

Technical Field

[0001] The utility model relates to the technical field of medical teaching tools, in particular to an ophthalmology teaching tool for simulating finger measurement of intraocular pressure. Background Art

[0002] Intraocular pressure, which is the pressure exerted by the contents of the eye on the wall of the eye, is an important examination indicator in many ophthalmic diseases, especially in the diagnosis and treatment of glaucoma, where intraocular pressure is one of the most critical examination items.

[0003] There are two main methods for measuring intraocular pressure, including finger pressure measurement and tonometer measurement. Finger pressure measurement is the earliest method of intraocular pressure examination. This measurement method does not rely on instruments and equipment. It only requires the examiner to use two fingers to measure. It is the most widely used in clinical practice. The specific examination method of finger pressure measurement is to let the patient look down naturally. The examiner touches the eyeball with the index fingertips of both hands from above the upper edge of the tarsal plate, and the other fingers are placed on the patient's forehead for support. The two index fingertips press lightly alternately, and estimate the level of intraocular pressure based on the fluctuation sense transmitted to the fingertips. Generally, normal is Tn, high intraocular pressure is T+1, +2, +3, and low intraocular pressure is T-1, -2, -3. Finger pressure measurement is not only the basic skill of ophthalmologists; it is also an important part of glaucoma patient education. Patients can use finger pressure measurement to evaluate their intraocular pressure by themselves. When they feel that the eyeball is harder than usual and suspected of high intraocular pressure, they can seek medical treatment in time to control the high intraocular pressure. Moreover, patients who have undergone external filtration surgery for glaucoma often need to undergo eye massage. The technique and strength of eye massage are based on the finger measurement of intraocular pressure. Therefore, learning the method of finger measurement of intraocular pressure is not only a necessary skill for ophthalmologists, but also an important part of the education of glaucoma patients.

[0004] However, the existing technology has the following problems: 1. There is no model that simulates the actual intraocular pressure of the human eye in clinical work. In teaching practice, the level of intraocular pressure is explained through metaphors, which cannot accurately feel the level of intraocular pressure. 2. The intraocular pressure is measured subjectively by the tester. The existing teaching has scene simulation scenes and teaching props that accurately perceive the level of intraocular pressure, and the teaching efficiency is not high.

[0005] Therefore, it is necessary to invent a teaching tool for ophthalmology simulating finger measurement of intraocular pressure to solve the above problems. Utility Model Content
