Corneal sensation pen

Abstract

The invention discloses a corneal sensation pen. The corneal sensation pen comprises a shell; an auxiliary mechanism is arranged at the top of the shell; a sliding plate is slidably connected to the bottom of one side of the inner wall of the shell; a nylon wire is fixedly connected to the top of the sliding plate; the top end of the nylon wire penetrates through the shell and extends to the top of the shell; a pointer is fixedly connected to the front face of the sliding plate; scales are engraved on one side of the front face of the shell; and a detection mechanism is arranged in the shell. The invention relates to the technical field of cornea detection. According to the corneal sensation pen, the corneal sensation detection can be conducted on a corneal injury patient, the numerical value of a stress between the nylon wire and the cornea when the nylon wire is bent can be automatically detected, then the pressure intensity can be conveniently calculated according to the length of the nylon wire during corneal sensation, and therefore the corneal injury degree of the patient can be conveniently calculated by a medical staff; due to the small size, the medical staff can conduct detection quickly without damage; and the detection can be conducted quickly without damage, so that the actual use requirement is met.

Description

technical field [0001] The invention relates to the technical field of cornea detection, in particular to a cornea sensing pen. Background technique [0002] The corneal sensory test is used to check whether the corneal sensation is normal. For example, when keratitis or ulcers are found without significant irritation symptoms, a corneal sensory test should be performed to determine whether the trigeminal nerve has decreased function or paralysis symptoms. If the sensory sensation is normal , when the cornea is touched, there will be a reflexive blink immediately. If the reflex is slow, it means that there is a decrease in perception. If the perception disappears completely, there will be no aftertouch. The same test should be performed on both eyes for comparison and comparison. Judgment, make the patient take a sitting position and stare straight ahead, or lightly turn the eyeballs in various directions to be inspected, and touch the cornea vertically with a 0.11 mm diamet...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a corneal sensory pen, which solves the inaccuracy of data detected through artificial observation, and the value of force between the nylon thread and the cornea when it is bent cannot be known, and it is not convenient to obtain It is easy for medical personnel to calculate the degree of corneal damage of the patient, and the market lacks a medical device for detecting corneal perception.
