Abstract

本发明公开了一种具备红绿色盲检测的视力表,包括矩形的板体,板体内成型有两道贯穿板体上端面的插槽,插槽内分别插接有黑色插板和红色插板,板体的前端面成型有若干行大小不一、朝向不同的E字形凹槽,E字形凹槽和板体相邻的插槽相连通,板体的前端面上喷涂有绿色涂层;两道插槽之间的板体成型有若干道与E字形凹槽相对的切槽,切槽连通板体内的两道插槽。本发明结构简单,制造方便,其在具备普通视力检测能力的基础上,还能用于检测红绿色盲。

Description

一种具备红绿色盲检测的视力表
技术领域:
本发明涉及医学视力检测器具的技术领域,更具体地说涉及一种具备红绿色盲检测的视力表。
背景技术:
视力表是用于测量视力的图表。医学检测所用视力表主要检查的是中心视力,即检查视网膜黄斑区中心凹视敏度,从而可简单迅速地了解到视功能的初步情况,对眼病的临床诊断治疗都有重要的意义。现有的视力虽然有国际标准视力表、对数视力表、兰氏环视力表,但其一般均为白底黑字,只具备近视或远视的检测功能。
发明内容:
本发明的目的就是针对现有技术之不足,而提供了一种具备红绿色盲检测的视力表,其在具备视力检测功能的同时,还能检测红绿色盲。
为实现上述目的,本发明采用的技术方案如下:
一种具备红绿色盲检测的视力表,包括矩形的板体,板体内成型有两道贯穿板体上端面的插槽,插槽内分别插接有黑色插板和红色插板,板体的前端面成型有若干行大小不一、朝向不同的E字形凹槽,E字形凹槽和板体相邻的插槽相连通,板体的前端面上喷涂有绿色涂层;两道插槽之间的板体成型有若干道与E字形凹槽相对的切槽,切槽连通板体内的两道插槽。
所述黑色插板或红色插板的上端面上均成型有支耳。
所述板体上端面的两侧成型有挂耳,挂耳的后端面和板体的后端面相齐平。
每行所述的E字形凹槽两侧的板体上成型有等差级数。
本发明的有益效果在于:其结构简单,制造方便,其在具备普通视力检测能力的基础上,还能用于检测红绿色盲。
附图说明:
图1为本发明正视的结构示意图;
图2为本发明侧视方向剖视的结构示意图。
图中:1、板体;11、插槽;12、E字形凹槽;13、等差级数;14、挂耳;15、切槽;2、绿色涂层;3、黑色插板;4、红色插板;a、支耳。
具体实施方式:
实施例:见图1、2所示,一种具备红绿色盲检测的视力表,包括矩形的板体1,板体1内成型有两道贯穿板体1上端面的插槽11,插槽11内分别插接有黑色插板3和红色插板4,板体1的前端面成型有若干行大小不一、朝向不同的E字形凹槽12,E字形凹槽12和板体1相邻的插槽11相连通,板体1的前端面上喷涂有绿色涂层2;两道插槽11之间的板体1成型有若干道与E字形凹槽12相对的切槽15,切槽15连通板体1内的两道插槽11。
所述黑色插板3或红色插板4的上端面上均成型有支耳a。
所述板体1上端面的两侧成型有挂耳14,挂耳14的后端面和板体1的后端面相齐平。
每行所述的E字形凹槽12两侧的板体1上成型有等差级数13。
工作原理:本发明为医学检测的视力表,将现有视力表上的黑色字体部分的E字形符号改为E字形凹槽12,并将视力表的白底改为绿底,当黑色插板3位于视力表板体1的前侧时,通过E字形凹槽12看到的为黑字,可以作为普通的视力表使用,而当红色插板4移动到视力表板体1的前侧时,通过E字形凹槽12看到的为红字,则和绿底的背景一起可以配合用于检测红绿色盲。
