Abstract
The present invention relates to a remote control self-testing eyesight meter, which belongs to a product in the medical appliance manufacturing technology field. The eyesight meter consists of a display, convertible characters, a remote controller and a direction button. There is a character window on the eyesight meter display, the direction button on the remote controller is inserted in the remote controller, and the eyesight meter display is connected with the remote controller via a 'Bluetooth' wireless system. During use, the power is switched on, and the testee manually holds the remote controller. When the testing characters are on, the testee shall make accurate direction selection in the required time, and the display widow will show smaller characters. When the character direction cannot be selected accurately, the buzzer gives an alarm and smaller testing characters will not be provided any longer. The eyesight meter has such advantages as reasonable design, simple structure and convenient use etc.
Description
Technical field
The present invention relates to a kind of remote control visual acuity chart of testing oneself, belong to manufacture technology field of medical appliance.
Background technology
When common logarithmic visual acuity chart is tested the tester, need tester and another people to assist to carry out, tester self can't detect the vision of oneself with logarithmic visual acuity chart, uses inconvenient.And because logarithmic visual acuity chart is a leaflet, and the direction of each symbol is fixed, can not randomly changing, so the somebody carried on the back symbol opening direction of each row in order to detect by vision, also can get by under false pretences, and lost the seriousness that detects.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, but provide a kind of reasonable in design, simple in structure, use reliable stochastic transformation character and remote control that can the single use visual acuity chart of testing oneself.
The objective of the invention is to be achieved through the following technical solutions: a kind of remote control visual acuity chart of testing oneself, form by visual acuity chart display, convertible character, remote controller and arrow button, wherein, the visual acuity chart display is provided with the character window, arrow button on the remote controller is embedded in the remote controller housing, is connected by " bluetooth " wireless system between visual acuity chart display and the remote controller.
Described visual acuity chart display is made up of housing and display window, is arranged with " E " shape or " C " shape of dwindling by logarithmic relationship in the display window and detects character, and character is provided by liquid crystal display.
When the present invention used, with energized, the tester held remote controller, when the test character lights, in the time that requires, to make correct direction and select, display window will show littler character, in the time can not correctly selecting character direction, buzzer warning, and littler detection character no longer is provided.Advantages such as it is reasonable in design, simple in structure, easy to use that the present invention has.
Description of drawings
Fig. 1 is a visual acuity chart display device structure sketch map of the present invention;
Fig. 2 is a remote controller structural representation of the present invention.
Wherein: 1, visual acuity chart display, 2, the character window, 3, remote controller, 4, arrow button.
The specific embodiment
Embodiment: structure as shown in drawings, form by visual acuity chart display 1, character window 2, remote controller 3, arrow button 4, wherein, visual acuity chart display 1 is provided with the character window, arrow button on the remote controller 3 is embedded in the remote controller housing, is connected by " bluetooth " wireless system between visual acuity chart display 1 and the remote controller 3.Visual acuity chart display 1 is made up of housing and display window, is arranged with " E " shape or " C " shape of dwindling by logarithmic relationship in the display window and detects character, and character is provided by liquid crystal display.And energy stochastic transformation opening direction, the detection order is descending carries out successively, and the character that is detecting shows as high brightness and shows.Remote controller 3 is provided with the button of four direction up and down, the radio signal of its button is emitted to the receiving circuit in the visual acuity chart display, and by correcting errors that receiving circuit judgement direction is selected, when selection is correct, continuation detects to littler character, when selecting mistake, buzzer warning is also no longer when littler character detects use, with energized, the tester holds remote controller, when the test character lights, in the time that requires, to make correct direction and select, display window will show littler character, in the time can not correctly selecting character direction, buzzer warning, and littler detection character no longer is provided, the present invention has reasonable in design, simple in structure, advantage such as easy to use.
Claims (2)
1, a kind of remote control visual acuity chart of testing oneself, it is characterized in that, form by visual acuity chart display, convertible character, remote controller and arrow button, wherein, the visual acuity chart display is provided with the character window, arrow button on the remote controller is embedded in the remote controller housing, is connected by " bluetooth " wireless system between visual acuity chart display and the remote controller.
2, the remote control according to claim 1 visual acuity chart of testing oneself, it is characterized in that, described visual acuity chart display is made up of housing and display window, is arranged with " E " shape or " C " shape of dwindling by logarithmic relationship in the display window and detects character, and character is provided by liquid crystal display.
