Description
Technical field
The present invention relates to Medical Instruments technical field, be specifically related to a kind of heterophoria detection and instrument for training.
Background technology
Have multiple about heterophoric inspection apparatus, with the application closest to prior art be Changchun Aopu Opto-electronic Technology Co., Ltd. produce a kind of multifunctional sight detecting instrument and Portable Automatic electronics heterophoria somascope.
Optical technology, precision machinery technology and computer technology are comprehensively integrated by multifunctional sight detecting instrument, the position different from depending on target display by the optical eyepiece of replacing different focal matches, motor 5 drives each eyepiece group to make the various images producing to vary in size depending on target display be imaged onto each examination of visual acuity desired position, meet the condition required for every examination of visual acuity, in conjunction with Fig. 1.
Distant vision and contrast sensitivity check use the 4th eyepiece group 4, and display is in d position, and two display generate two identical images.
Examination of near vision uses the first eyepiece group 1, and display is in c position, and two display generate identical image.
Colour vision and stereopsis test are by the 3rd eyepiece group 3, and display is in b position, and examination of color sense display generates two identical images, and during stereopsis test, display generates two images having parallactic angle.
Heterophoria inspection is by the second eyepiece group 2, and display is in a position, and left view target display generates cross hairs, and the right side is looked target and generated round dot.
Achieve multinomial examination of visual acuity function by eyepiece group with the various combination of display and the change of position, thus traditional various eyesight exam methods have been integrated in a kind of instrument.
The shortcoming of above-mentioned multifunctional sight detecting instrument, although distant vision, contrast sensitivity's inspection, colour vision and stereopsis test, near vision, heterophoria inspection are integrated in an instrument, but it is big that this also result in price height, volume, quality weight, carrying inconvenience, in each detection purpose switches, easily cause leading screw clamping stagnation, the shortcomings such as noise is big, length consuming time, give and check that environment brings harmful effect.And in the inspection place having because without all of audit function, being often that the audit function having is left unused for a long time, cause the waste of resource.
Portable Automatic electronics heterophoria somascope operation principle illustrates: under the control of the computer, left and right display generates Cross ruler, luminous point respectively.According to while consciousness, eyes close picture principle produce two width images.Under the control of the computer, left and right display makes display graphical virtual be imaged on 5 meters remote and visual field that is that require.Examinee's left eye sees green Cross ruler, and right eye sees a red point.In the common visual field of binocular of examinee, Cross ruler and red dot center are misaligned, it is simply that examinee has heterophoria, and examinee moves the horizontal and vertical position of red point by the button of handle, until those who are investigated see that red point is in the middle position of Cross ruler.After the distance of red some movement write down by computer, convert out the prism degree of correspondence.Simultaneous computer can also calculate heterophoria value, and record or print.
In conjunction with Fig. 2, Portable Automatic electronics heterophoria somascope includes monitor 6, left and right display 8, optical system 9, housing 10, mini-printer 11, power supply 12, computer 17, keyboard case 13, keyboard 14, handle 15, supply socket 16, inner frame 18.Inner frame 18 is contained in housing 10, display bracket 7, is installation, the fixing carrier being respectively arranged with pass parts；Computer 17 is arranged on inner frame 18 lower rear, and both are connected with screw；Left and right display 8 is fixed on display bracket 7, and supply socket 16 is contained in the left side wall lower section to the rear of housing 10, and monitor 6 is embedded in housing 10 right side wall by middle position, and outwardly, examiner can direct viewing monitoring result for the display screen of monitor 6；Mini-printer 11, through housing 10 and inner frame 18, is contained in the just front position on the lower side of housing 10；Light-source system 9 is contained in the positive front upper place of housing 10, and keyboard case 13 is connected with housing 10 below housing 10 right side wall, and keyboard 14 is contained in keyboard case 13；Computer 17 is connected with wire with supply socket 16, and other left and right display 8, mini-printer 11, monitor 6, keyboard 14, handle 15 are connected with wire with computer system 17 respectively.
The shortcoming that Portable Automatic electronics heterophoria somascope exists: first, this instrument is merely capable of the detection heterophoria number of degrees, can not train and be effectively improved the adaptive capacity of the physiological function of people targetedly, current demand be can not meet for this somascope of some medical institutions；Secondly, when measured measures because lower jaw does not have relative adjustment fixed position, heterophoric testing result being had a certain impact, relative accuracy of detection cannot be effectively ensured.
Summary of the invention
