Simulation eyeball

Abstract

The invention provides a simulation eyeball, and relates to the medical teaching field. The simulation eyeball includes a front eyeball, a rear eyeball, a stepping motor expansion device, light guide bars, an iris, a pupil and a control circuit. The simulation eyeball can change the size of the pupil under the extraneous illumination stimulation, can change the color of the iris according to the requirement, and can satisfy the requirement for eye inspection for medical teaching.

Description

technical field [0001] The invention relates to the field of medical teaching, in particular to a simulated eyeball. Background technique [0002] The iris belongs to the middle layer of the eyeball, and the color of the human eyeball is mainly reflected by the color of the iris. There is a small round hole in the middle of the human eye, which is what we call the pupil, also called "pupil". It shrinks in bright light and expands in dark light. In the eye examination, especially the eye examination of critically ill patients, a flashlight is often used to irradiate the eyes to observe the reaction of the pupil to the light to determine the patient's physical condition. However, the existing eye medical teaching products often use pictures or videos to show the reaction of the pupils to external stimuli and the different colors of the iris, and there is a problem that the teaching effect is not intuitive.
