Description

Technical Field

[0001] This application relates to the field of eye testing equipment technology, and in particular to an integrated testing device for visual contrast sensitivity and light-dark adaptation functions. Background Technology

[0002] Visual contrast sensitivity is a core indicator for evaluating the visual system’s ability to distinguish stimuli of different spatial frequencies and contrasts, while visual light-dark adaptation is an indicator for evaluating the visual system’s ability to adjust to sudden changes in light intensity (from bright to dark or from dark to bright). Nowadays, integrated testing equipment for visual contrast sensitivity and light-dark adaptation is often used to perform the above-mentioned visual tests on personnel.

[0003] In some existing integrated examination devices, the examinee's eyes are first placed close to the device's sealing strip, and then the examinee's head movement is restricted. Then, when performing a visual contrast sensitivity test, the screen inside the device displays sinusoidal stripes (letters) of different spatial frequencies. The examinee judges the direction of the stripes (identifies the letters), and the examinee's visual contrast sensitivity data is obtained based on the examinee's judgment. When performing a visual light and dark adaptation function test, the device's screen presents a target stimulus with controllable brightness (continuously adjustable from strong light to dim light). The examinee needs to provide feedback on whether the target is visible, and the examinee's visual light and dark adaptation data is obtained based on the examinee's feedback.

[0004] However, because the above tests take a long time, the subjects' eyes are prone to dryness, which leads to frequent blinking. This causes the subjects' eyes to deviate from their observation of the screen, affecting the feedback results and thus the accuracy of the subjects' visual test data. Summary of the Invention

[0005] This application proposes an integrated examination device for visual contrast sensitivity and light-dark adaptation, which has the advantage of relieving dry eyes in examinees and solving the problem that frequent blinking by examinees affects the accuracy of their visual test data.

[0006] To achieve the above objectives, this application adopts the following technical solution: an integrated inspection device for visual contrast sensitivity and light / dark adaptation functions, comprising: a main body, an inspection component inserted into the interior of the main body, two lenses fixedly mounted on the side of the main body, a sealing strip fixedly mounted on the outer side of the lenses, a fixing plate disposed on the side of the main body facing the lenses, the fixing plate being driven by an externally mounted mobile device, and an air blowing mechanism disposed within the sealing strip, the air blowing mechanism comprising: The mounting base is fixedly installed in the middle position inside the sealing strip, with two lenses on both sides of the mounting base. The upper side of the mounting base is connected to the output end of the hot air component via a flexible hose. The main hole is located inside the mounting base. The upper port of the main hole is connected to the flexible hose, and the lower port of the main hole is a bidirectional port. The bidirectional ports of the main hole face the two sides of the mounting base and the lower inner wall of the sealing strip, respectively. The atomizer is fixedly installed on the lower side of the middle position of the sealing strip. The upper output end of the atomizer extends into the mounting base and is located in the middle position of the bidirectional port of the main hole. The water collection bottle is fixedly connected to the lower input end of the atomizer; The vent is located on the upper side of the mounting base and on both sides of the connecting hose. The vent connects the external environment with the inner area of ​​the sealing strip.

[0007] Furthermore, the hot air component includes: The air pump is located on the outer side of the main body; A blower is fixedly installed on one side of the air cylinder, and the output end of the blower is connected to the inner cavity of the air cylinder; The heating column is fixedly installed inside the air cylinder and located above the blower; One end of the hose is connected to the port of the air cylinder.

[0008] Furthermore, a baffle is fixedly installed on the inner side of the sealing strip and on the upper side of the lens. There is a gap between both sides of the baffle and the side wall of the sealing strip. The lower port of the air outlet is located between the baffle and the upper inner wall of the sealing strip. The side of the baffle facing away from the main body and the side of the upper side wall of the sealing strip facing away from the main body are on the same longitudinal path.

[0009] Furthermore, a temperature and humidity sensor is fixedly installed on the side of the sealing strip, and the sensing end of the temperature and humidity sensor extends into the inner area of ​​the sealing strip. The temperature and humidity sensor forms a remote control electrical connection with the heating column and the atomizer, respectively.

[0010] Furthermore, a drying mechanism is provided on the inner side of the sealing strip, the drying mechanism comprising: A surrounding tube is disposed in the inner area of ​​the sealing strip, and the surrounding tube is fixedly sleeved on the outer side of the lens; A branch pipe is fixedly installed on the side of the mounting base facing the lens, and the branch pipe connects the middle position of the main hole with the inner area of ​​the surrounding cylinder.

[0011] Furthermore, the drying mechanism also includes: An opening is provided at one end of the branch pipe facing the surrounding cylinder, forming a tangential transition connection with the inner wall of the surrounding cylinder. An opening is provided through the inside of the surrounding cylinder and above the branch pipe, with the opening facing the position between the baffle and the mounting base.

[0012] Furthermore, an airflow groove is provided on the side of the sealing strip facing away from the main body. The airflow groove is located on both sides of the mounting base. The opening of the airflow groove is opened on the side of the sealing strip facing away from the main body. The airflow groove is opened at one-third of the outer side of the side of the sealing strip. The lower end of the airflow groove is opened on the lower inner wall of the sealing strip. The upper end of the airflow groove is opened on the upper inner wall of the sealing strip and faces downward toward the baffle. The sealing strip is made of soft silicone.

[0013] Furthermore, a wind-facing block is fixedly installed on the lower inner wall of the sealing strip, and the lower end port of the airflow groove is opened on the side of the wind-facing block facing the mounting base.

[0014] This application has the following beneficial effects: This application provides an integrated examination device for visual contrast sensitivity and light / dark adaptation functions. Through the setting of the blowing mechanism, warm air is blown into the closed area of ​​the eye using a hot air component. Then, the warm air drives the water mist sprayed by the nebulizer to flow around the skin of the eye, gently moisturizing the ocular surface, avoiding shortening the tear film breakup time, thereby relieving the symptoms of dry eyes. At the same time, the warm and moist air dilates the capillaries around the eye, accelerates blood flow, and reduces the soreness caused by the skin of the eye being tightly pressed against the sealing strip. This makes it easier for the examinee to maintain the observation posture and reduces the impact on the accuracy of the examinee's visual test data.

[0015] By setting up a baffle, the air outlet path is extended, allowing warm and humid air flowing around the skin of the eye to be released when it reaches the position between the baffle and the sealing strip. This prevents the warm and humid air from escaping due to weakened airflow, thus preventing it from directly contacting the eyeball. This makes the accuracy of the visual test data less affected. At the same time, by blocking the air outlet, external light is prevented from shining into the closed area of ​​the eye through the air outlet, making the test data of visual light and dark adaptation less affected.

[0016] By incorporating a drying mechanism, a baffle, and an air blowing mechanism, when the hot air component blows warm air into the enclosed area of ​​the eye, some of the warm air is tangentially blown into the inner wall of the surrounding tube through a branch pipe, thereby drying the lens surface inside the surrounding tube. This prevents moisture from forming water vapor on the lens, thus minimizing the impact on the accuracy of the subject's visual test data. Subsequently, the warm air is discharged through an opening to the position between the mounting base and the baffle, causing the warm air to flow along both, which in turn propels the air in that path. This allows any moisture that has escaped to that position to re-contact the skin around the eye or be expelled, preventing moisture from directly contacting the eyeball and thus reducing the impact on the accuracy of the subject's visual test data.

[0017] By incorporating an air blowing mechanism and airflow channels, as warm, moist air flows along the skin around the eyes, some of it enters the airflow channels, forming an extremely thin air film between the skin and the sealing strip. The compressibility of the gas disperses the local pressure on the sealing strip, reducing the pressure per unit area on the skin around the eyes. This alleviates the soreness caused by the skin tightly adhering to the sealing strip, making it easier for the examinee to maintain an observation posture and reducing the impact on the accuracy of visual test data. Simultaneously, the warm, moist air reduces the elastic modulus of the sealing strip, making it softer and transforming the hard contact with the skin into a soft fit, further dispersing pressure and reducing the soreness caused by the skin tightly adhering to the sealing strip.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Example 1: Please refer to Figures 1-6 A visual contrast sensitivity and light / dark adaptation integrated examination device includes a main body 1. An examination component 2 is inserted into the main body 1. The examination component 2 is a combination of a display screen and a power supply. Two lenses 3 are fixedly installed on the side of the main body 1. The examinee observes the display screen of the examination component 2 through the lenses 3. A sealing strip 4, made of soft silicone, is fixedly installed on the side of the main body 1, outside the lenses 3. The skin around the examinee's eyes adheres to the sealing strip 4, forming a sealed area to block external light from entering. A fixing plate 5 is provided on the side of the main body 1 facing the lenses 3. The fixing plate 5 is moved closer to or away from the main body 1 by an externally mounted device. An air blowing mechanism 6 is provided inside the sealing strip 4. The air blowing mechanism 6 includes a mounting base 60, a hose 61, a hot air component 62, a main port 63, an atomizer 64, a water collection bottle 65, and an air outlet 66. The mounting base 60 is fixedly installed inside the sealing strip 4. The two lenses 3 are positioned on either side of the mounting base 60. The upper side of the mounting base 60 is connected to the output end of the hot air component 62 via a hose 61. The mounting base 60 has a main hole 63 inside. The upper end of the main hole 63 is connected to the hose 61, and the lower end of the main hole 63 is a bidirectional port. The bidirectional ports of the main hole 63 face the two sides of the mounting base 60 and the lower inner wall of the sealing strip 4. An atomizer 64 is fixedly installed on the lower side of the middle position of the sealing strip 4. The upper output end of the atomizer 64 extends into the mounting base 60 and is located in the middle of the bidirectional port of the main hole 63. The lower input end of the atomizer 64 is fixedly connected to a water collection bottle 65. An air outlet 66 is provided on both sides of the upper side of the mounting base 60, which is located at the position of the connecting hose 61. One end of the air outlet 66 is connected to the external environment, and the other end of the air outlet 66 is connected to the inner area of ​​the sealing strip 4.

[0023] In use, the examinee's eyes are first placed close to the sealing strip 4 to form a closed area around the eyes. Then, the mobile device moves the fixing plate 5 closer to the main body 1 until the fixing plate 5 lightly presses down on the examinee's head, thus restricting the examinee's head movement. Then, when performing a visual contrast sensitivity test, the display screen of the examination piece 2 displays sinusoidal stripes (letters) of different spatial frequencies. The examinee observes and judges the direction of the stripes through the lens 3 (identifying the letters). Based on the examinee's judgment, the examinee's visual contrast sensitivity data is obtained. When performing a visual light and dark adaptation function test, the display screen of the examination piece 2 presents a target stimulus with controllable brightness (continuously adjustable from strong light to dim light). The examinee needs to provide feedback on whether the target is visible. Based on the examinee's feedback, the examinee's visual light and dark adaptation data is obtained. During the above process, the hot air component 62 and the nebulizer 64 operate at regular intervals, so that the warm air (temperature between 32-35 degrees Celsius) delivered by the hot air component 62 is blown through the hose 61 and the main hole 63 to the lower inner wall of the sealing strip 4, and moves upward along the inner wall of the sealing strip 4 to the air outlet 66 for discharge. At the same time, the nebulizer 64 sprays water mist into the main hole 63 (the nebulizer 64 is a miniature high-frequency ultrasonic nebulizer, so that the generated water mist droplet particle size is controlled at the submicron level). This causes the warm air to move synchronously with the water mist sprayed by the nebulizer 64, and flow around the skin around the eyes, gently moisturizing the ocular surface, avoiding shortening the tear film breakup time, thereby relieving the symptoms of dry eyes and reducing the impact on the accuracy of the visual test data of the examinee. At the same time, the warm and humid air will dilate the capillaries around the eyes and accelerate blood flow, thereby reducing the soreness caused by the skin of the eyes being in close contact with the sealing strip 4, making it easier for the examinee to maintain the observation posture, further reducing the impact on the accuracy of the visual test data of the examinee. After the visual inspection is completed, the hot air unit 62 and the atomizer 64 are turned off, and the mobile device moves the fixing plate 5 away from the main body 1, so that the movement of the subject's head is unrestricted.

[0024] Please see Figure 1 and Figure 2 The hot air component 62 includes an air cylinder 620, a fan 621, and a heating column 622. The air cylinder 620 is located on the outer side of the main body 1. The fan 621 is fixedly installed on one side of the air cylinder 620. The output end of the fan 621 is connected to the inner cavity of the air cylinder 620. The heating column 622 is fixedly installed in the inner cavity of the air cylinder 620 and above the fan 621. One end of the hose 61 is connected to the port of the air cylinder 620.

[0025] When the hot air component 62 is running, the heating column 622 operates first, so that the inner cavity of the air cylinder 620 is in a heated environment. Then, the fan 621 operates and draws outside air into the air cylinder 620. The drawn-in air is heated when it passes through the heating column 622. Then, the heated air enters the main hole 63 through the hose 61, thereby realizing the delivery of warm air.

[0026] To prevent warm, humid air from directly contacting the eyes, please refer to [link / reference]. Figures 1-6 A baffle 7 is fixedly installed on the inner side of the sealing strip 4 and on the upper side of the lens 3. There is a gap between both sides of the baffle 7 and the side wall of the sealing strip 4. The lower end of the air outlet 66 is located between the baffle 7 and the upper inner wall of the sealing strip 4. The side of the baffle 7 facing away from the main body 1 and the side of the upper side wall of the sealing strip 4 facing away from the main body 1 are on the same longitudinal path.

[0027] When the subject's eye is pressed against the sealing strip 4, the eye skin is simultaneously pressed against the baffle 7, so that the space between the baffle 7 and the sealing strip 4 is only connected to the air outlet 66. This action extends the air outlet path of the air outlet 66, so that when the warm and humid air flowing around the eye reaches the position between the baffle 7 and the sealing strip 4, it can be vented. This prevents the warm and humid air from escaping due to the weakening of the warm and humid air's momentum, and thus prevents the warm and humid air from directly contacting the eyeball, so that the accuracy of the subject's visual test data is not easily affected. At the same time, the baffle 7 blocks the air outlet 66 to prevent external light from shining directly into the closed area of ​​the eye through the air outlet 66, so that the test data of the visual light and dark adaptation function is not easily affected.

[0028] To prevent overheating and excessive moisture in the inner area of ​​the sealing strip 4, please refer to... Figures 1-6 A temperature and humidity sensor 8 is fixedly installed on the side of the sealing strip 4. The sensing end of the temperature and humidity sensor 8 extends into the inner area of ​​the sealing strip 4. The temperature and humidity sensor 8 forms a remote control electrical connection with the heating column 622 and the atomizer 64 respectively.

[0029] The temperature and humidity sensor 8 senses the temperature and humidity of the inner area of ​​the sealing strip 4. When the temperature is maintained at 32-35 degrees and the humidity is maintained at 50-60% (when the humidity is too high, water vapor is more likely to condense on the surface of the lens 3, resulting in blurred imaging; when the temperature is too high, the eyes will feel hot and tear up, which will further affect the visual detection results), the temperature and humidity sensor 8 will not work. When the temperature or humidity exceeds the limit, the temperature and humidity sensor 8 sends a signal to the heating column 622 or the atomizer 64, causing the corresponding equipment to stop operating until the temperature or humidity returns to the normal standard.

[0030] To prevent fogging on the surface of lens 3, please refer to Figures 1-6 A drying mechanism 9 is provided on the inner side of the sealing strip 4. The drying mechanism 9 includes a surrounding cylinder 90 and a branch pipe 91. The surrounding cylinder 90 is located in the inner area of ​​the sealing strip 4 and is fixedly sleeved on the outer side of the lens 3. The side of the mounting base 60 facing the lens 3 is fixedly installed with the branch pipe 91. One end of the branch pipe 91 facing the mounting base 60 is connected to the middle position of the main hole 63, and the other end of the branch pipe 91 facing the surrounding cylinder 90 is connected to the inner area of ​​the surrounding cylinder 90.

[0031] When the hot air component 62 is working, some of the warm air entering the main hole 63 will enter the surrounding cylinder 90 through the branch pipe 91, thereby blowing the lens 3 inside the surrounding cylinder 90, keeping the lens 3 dry at all times, so that moisture will not form water mist on the lens 3, thus making the accuracy of the visual test data of the examinee less likely to be affected.

[0032] To prevent warm air from blowing directly into the eyes, please refer to [link / reference]. Figures 1-6 The drying mechanism 9 also includes an opening 92. One end of the branch pipe 91 facing the surrounding cylinder 90 forms a tangential transition connection with the inner wall of the surrounding cylinder 90. An opening 92 is provided inside the surrounding cylinder 90 and above the branch pipe 91. The opening 92 faces the position between the baffle 7 and the mounting base 60.

[0033] By forming a tangential transition between the branch pipe 91 and the inner wall of the surrounding cylinder 90, the warm air entering the surrounding cylinder 90 through the branch pipe 91 flows circumferentially along the inner wall of the surrounding cylinder 90, thereby increasing the heating area of ​​the lens 3 and promoting a better drying effect of the lens 3, so that the accuracy of the visual test data of the examinee is less likely to be affected. Afterwards, the warm air inside the surrounding tube 90 will be discharged through the opening 92. This action prevents the warm air from flowing axially, making it less likely for the air to blow directly onto the eyeball, thus avoiding frequent blinking by the examinee and making the accuracy of the examinee's visual test data less likely to be affected. Subsequently, the warm air is discharged through the opening 92 to the position between the mounting base 60 and the baffle 7, causing the warm air to move along the two, thereby boosting the air in this path, so that the moisture that has escaped to this position will re-contact the skin around the eyes or be discharged, making it less likely for the moisture to directly contact the eyeball, avoiding the subject blinking frequently, and thus reducing the impact on the accuracy of the subject's visual test data.

[0034] Example 2: To alleviate soreness and swelling around the eyes, please refer to... Figures 1-6 An airflow groove 10 is provided on the side of the sealing strip 4 facing away from the main body 1. The airflow groove 10 is located on both sides of the mounting base 60. The opening of the airflow groove 10 is opened on the side of the sealing strip 4 facing away from the main body 1. The airflow groove 10 is opened at one-third of the outer side of the side of the sealing strip 4. The lower end of the airflow groove 10 is opened on the lower inner wall of the sealing strip 4. The upper end of the airflow groove 10 is opened on the upper inner wall of the sealing strip 4 and faces downward toward the baffle 7.

[0035] When the subject's eyes are pressed tightly against the sealing strip 4, the skin of the eyes blocks the opening of the airflow groove 10. Then, as warm and humid air is sprayed out from the main hole 63, some of the warm and humid air will enter the airflow groove 10 through the lower port, thereby forming an extremely thin air film between the skin and the sealing strip 4. The compressibility of the gas is used to disperse the local pressure of the sealing strip 4, reduce the pressure per unit area of ​​the skin around the eyes, thereby reducing the soreness caused by the skin of the eyes being pressed tightly against the sealing strip 4, making it easier for the subject to maintain the observation posture and reducing the impact on the accuracy of the subject's visual test data. At the same time, when the warm and humid air comes into contact with the sealing strip 4, it will reduce the elastic modulus of the sealing strip 4, making the sealing strip 4 softer, and the hard contact when it is attached to the skin will become a soft contact, further dispersing the pressure, reducing the soreness caused by the skin of the eyes being tightly attached to the sealing strip 4, and reducing the impact on the accuracy of the visual test data of the examinee. After that, the warm and humid air is discharged to the air outlet 66 through the upper port of the airflow groove 10. In addition, since the airflow channels 10 are only opened at the outer third of the sealing strip 4, the inner two-thirds of the sealing strip 4 remain completely fitted, preventing light leakage. Finally, after the subject has finished the test, the nebulizer 64 is turned off and the hot air component 62 is run for a short time, so that warm air passes through the airflow channel 10 and dries the area where the sealing strip 4 contacts the skin around the eyes, preventing the skin from sticking together due to moisture when it comes off.

[0036] To encourage more warm and humid air to enter the airflow tank 10, please refer to... Figures 1-6 A wind-facing block 11 is fixedly installed on the lower inner wall of the sealing strip 4, and the lower end port of the airflow groove 10 is opened on the side of the wind-facing block 11 facing the mounting base 60.

[0037] By setting the wind-facing block 11, some of the warm and humid air ejected from the main hole 63 directly hits the wind-facing block 11 and enters the airflow groove 10, thereby increasing the amount of gas in the airflow groove 10. The function of the airflow groove 10 is effectively utilized, thereby reducing the soreness caused by the skin of the eyes being tightly pressed against the sealing strip 4, and reducing the impact on the accuracy of the visual test data of the examinee.
