Technical Field
[0001] The present invention relates to a method and device for adaptively adjusting the position of a light energy source of a medical device. Background Art
[0002] The light energy source achieves the medical or health care effect on the eye by emitting light within a preset wavelength range to the eye. In practical applications, the light energy source can be used for eye diseases such as myopia, amblyopia, age-related macular degeneration (AMD), diabetic retinopathy, glaucoma, etc. With the increasing incidence of myopia among teenagers in our country, taking the treatment or care of myopic patients as an example, there is research showing that when the laser wavelength emitted by the light energy source is preset within the laser wavelength range that can treat or care for myopia, when the light energy emitted by the light energy source of this wavelength is applied to the eyes of myopic patients, it can induce the retina to produce and release dopamine, which can slow down and inhibit the development of myopia.
[0003] Existing devices for treating ophthalmic diseases by irradiating the retina with light usually cannot ensure that the light always irradiates on the pupil position of the user according to the change of the pupil position of the user. In the Chinese utility model with the publication number CN213374769U, a pulley adjustment structure for a light source generating device is disclosed. This patent symmetrically adjusts two light source generators when different users use the medical device to change the horizontal distance between the light source generators so that the light source generators irradiate on the user's eyes. However, the disadvantages of the current ophthalmic medical devices on the market are as follows: 1. When different users use the same machine, it is necessary to readjust the light source position to irradiate the pupil, and the information of different users cannot be recognized; 2. When different users use the pupil of the same ophthalmic medical device, the light energy source cannot be automatically adjusted to irradiate the center of the user's pupil. Therefore, it is necessary to provide a method and device for adaptively adjusting the position of the light energy source of the medical device. Summary of the Invention

Detailed implementation
[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0048] As Figure 1 shown, in an embodiment provided by the present invention, a medical device for applying light energy to the eye includes a light energy source 20, an image capture device 30, and a processing and control unit 40. At least part of the light emitted by the light energy source 20 is guided to the user's eye 10. The image capture device 30 is configured to acquire eye image information, and the processing and control unit 40 processes the eye image information to obtain information related to the user's usage situation. The medical device 1 of the present invention can be used for treating, but not limited to, eye diseases such as myopia, amblyopia, age-related macular degeneration (AMD), diabetic retinopathy, glaucoma, etc.
[0049] Specifically, taking the example of a user using a medical device for applying light energy to the eye of the present invention to treat myopia, after the image capture device 30 acquires the eye image information, it transmits the information to the processing and control unit 40. After receiving the information transmitted by the image capture device 30, the processing and control unit 40 calculates and obtains information related to the usage situation of the user's human eye. Further, the information related to the user's usage situation at least includes one or a combination of more than one of the information on whether the user opens the eyes and uses correctly, the user's pupil diameter information, the user's pupil fixation angle information, the position information of the user's pupil, the information for identifying the user, the user's effective usage time information, the total light power received by the user's eye 10, and the user's interpupillary distance information, that is, by algorithm processing to correct the non-standard user usage situations such as closing the eyes during the user's use, and to ensure the treatment effect during the user's use process.
[0050] In an embodiment of the present invention, a medical device for applying light energy to an eye further includes a light distribution component 60 and a light detector 80 for detecting light intensity. The light distribution component 60 guides at least a part of the light rays emitted by the light energy source 20 to the light detector 80 to detect the emission light intensity of the light energy source. The light distribution component 60 guides another part of the light rays emitted by the light energy source 20 to the user's eye 10. The reflected light guided to the user's eye 10 enters the image capture device 30 through the light distribution component 60 to obtain eye image information.
[0051] Furthermore, when a user uses a medical device for applying light energy to an eye, the light energy source 20 is an LED light source or a laser light source. The light waves emitted by the LED light source or the laser light source are partially received by the light detector 80 through the light distributor. Another part of the light waves emitted by the light energy source 20 is received by the user's eye 10, and the reflected light through the eye 10 is reflected on the image capture device 30 through the light distribution component 60.
[0052] Even further, the light energy source 20 is a controllable light source, and the wavelength and / or light intensity of the controllable light source can be adjusted. The processing control unit 40 includes a processor 401 and a memory 402. The memory 402 is configured to store a correspondence table between the eye image information and the emission light intensity of the light energy source 20. The emission light intensity of the light energy source 20 and the eye image information obtained by the image capture device 30 are transmitted to the processor 401. The processor sends a signal to the controllable light source to adjust the light intensity of the controllable light source according to the received emission light intensity, eye image information, and the correspondence table.
[0053] Specifically, the eye image information at least includes the user's pupil diameter information. The memory 402 is configured to store a correspondence table between the user's pupil diameter information and the emission light intensity. The processing control unit 40 adjusts the light intensity of the controllable light source according to the real-time received emission light intensity, user's pupil diameter information, and the correspondence table. For example, when the pupil diameter captured by the image capture device 30 shrinks, the processor 401 can send a signal to the controllable light source to slightly increase the emission light intensity.
[0054] Specifically, the light distributor can be a beam splitter, which is used to divide the emission light source into two beams of light, one reflected downward and the other directly leftward. The splitting ratio of the beam splitter can be selected and set by the manufacturer. For example, the beam splitter can allow 50% of the light rays emitted by the light energy source 20 to enter the user's eye 10 and 50% of the light rays emitted by the light energy source 20 to enter the light detector 80, so that the light detector 80 can accurately detect the optical power emitted by the light energy source 20.
[0055] Such as Figure 2As shown, in a preferred embodiment, at least one filter element 70 is provided between the light energy source 20 and the light distribution component 60, or between the light detector 80 and the light distribution component 60, or between the image capture device 30 and the light distribution component 60. Specifically, the filter element 70 can be a band-pass filter, a low-pass or high-pass filter. In this embodiment, a band-pass filter is provided between the light energy source 20 and the light distribution component 60. When the light energy source 20 emits light waves, the light waves pass through the band-pass filter to purify the wavelength. Further, for example, the light wavelength emitted by the light energy source 20 is in the range of 650 - 680 nm. When the light waves emitted by the light energy source 20 pass through the band-pass filter, the wavelength with a wider full width at half maximum can be reduced to a wavelength range with a narrower full width at half maximum.
[0056] When the light waves emitted by the light energy source 20 pass through the band-pass filter between the light energy source 20 and the light distribution component 60, to prevent the remaining stray light from being reflected to the image capture device 30 and thus affecting the shooting of the image capture device 30, a low-pass or high-pass filter is provided between the image capture device 30 and the light distribution component 60 to filter out the light waves emitted by the light energy source 20, leaving only a small part for specific cues in the image, so that the image capture device 30 will not exceed the reasonable dynamic range due to excessive light intensity, ensuring the safety of user use.
[0057] In this embodiment, the same band-pass filter as that between the light energy source 20 and the light distribution component 60 is provided between the light distribution component 60 and the light detector 80. Similarly, when the laser emitted by the light energy source 20 reaches the light detector 80 through the light distribution component 60, it is used to block the stray light in the light waves, thus ensuring the accuracy of the measurement of the light detector 80. By accurately detecting the incident light intensity and the eye state, the closed-loop monitoring of the light intensity output of the light energy source 20 is truly realized, improving the safety and reliability of the medical device of the present invention.
[0058] At least one collimating element 90 for focusing the light rays emitted by the light energy source is provided between the light energy source 20 and the light distribution component 60. Specifically, when the light energy source 20 emits light waves, the light waves pass through the collimating element 90 and irradiate on the beam splitting accessory. The light waves emitted by the light energy source 20 pass through the collimating element 90 to turn the divergent light into parallel light, shortening the light source to a parallel light spot with a diameter of about 10 mm covering the human eye, ensuring the stability of the light source.
[0059] In this embodiment, at least one focusing element 100 is provided between the image capturing device 30 and the light distribution component 60. The focusing element 100 is used to adjust the appropriate detection focus. When the image capturing device 30 captures the user's eye information, in order to ensure that the detected image of the eye position captured is the clearest, the focusing element 100 is provided in front of the image capturing device 30, so that the image capturing device 30 can capture the clearest eye information through the appropriate detection focus. Through the improvement of the optical path of the present invention, the volume of the medical device applying light energy to the eye is greatly reduced, the overall structure can be made more lightweight, and it is convenient for users, especially young users, to use.
[0060] In a preferred embodiment, the present invention further includes a constant temperature device for providing a set working environment temperature for the light detector 80 and / or the light energy source 20. Specifically, in order to ensure that the medical device 1 of the present invention has a wide output working range and detection accuracy, the constant temperature device can be controlled to work by the processing control unit 40. For example, the ideal working environment temperature is 25 °C. When the external temperature is higher or lower than 25 °C, the processing control unit 40 controls the constant temperature device to start working and keep the working environment temperature constant at 25 °C. The constant temperature device can be in the form of a TEC cooler, a compressor, etc.
[0061] In the calibration stage before the ophthalmic medical device 1 of the present invention is used, the light energy source 20 and the light detector 80 can be calibrated by using a metrologically certified device to test on the user's eye. During the actual use of the user thereafter, the actual light intensity can be monitored according to this curve. The light energy source 20 in this embodiment is a controllable light source, and the wavelength and / or light intensity of the controllable light source can be adjusted. The controllable light source adjusts the output light intensity according to the user's pupil diameter information obtained by the image capturing device 30.
[0062] Specifically, when the user uses the medical device 1 provided by the present invention, the image capturing device 30 captures eye information by photographing the human eye and transmits it to the processing control unit 40, such as the pupil diameter. Further, the processing control unit 40 dynamically adjusts the emission value of the light source according to the calculated pupil diameter size. When the image capturing device 30 captures a change in the human eye pupil, the processing control unit 40 calculates the pupil diameter size again according to the captured image. If the calculation result is smaller than the pupil diameter size calculated in the previous capture, it is determined that the pupil has constricted. The processing control unit 40 controls the light energy source 20 to increase the emission light intensity, thereby improving the accuracy of the incident light intensity and ensuring that the accumulated incident light intensity is a fixed value, making the clinical data more consistent. The image capturing device 30 is an invisible light camera (such as an infrared camera) or a visible light camera, and there is no limitation here.
[0063] Refer to Figure 3 and Figure 4, in another embodiment of the present invention, an ophthalmic medical device 1 with user identification function includes a light energy source 20, an image capture device 30 and a processing and control unit 40. At least part of the light rays emitted by the light energy source 20 is guided to the user's eye 10. For example, the light energy source 20 can be two LED light sources or two laser light sources, which are respectively arranged in the left and right barrels of the medical device 1. The image capture device 30 in this embodiment is configured to obtain the iris information of the user's eye 10, and the processing and control unit 40 is configured to process the iris information to obtain user identification information. Specifically, when the user uses the ophthalmic medical device 1 provided by the present invention, the image capture device 30 obtains the iris information of the user's eye 10 through shooting. After the image capture device 30 obtains the iris information of the user's eye 10, the obtained information is transmitted to the processing and control unit 40. The processing and control unit 40 calculates through the obtained user iris information and obtains the user's identification information. The processing and control unit 40 can control the light energy to output different user configuration parameters for different users. For example, the output power of the light energy source 20 corresponding to different users is different.
[0064] In this embodiment, the processing and control unit 40 includes a processor 401 and a memory 402. The memory 402 is configured to store an iris database corresponding to the user identification information. The processor 401 is configured to compare the iris information with the iris database. If the iris information is consistent with the iris data in the iris database, the processor 401 obtains the user identification information corresponding to the consistent iris data.
[0065] Further, after the processing and control unit 40 receives the human eye iris information captured by the image capture device 30, it is distributed to the processor 401 and the memory 402. When different users use the ophthalmic medical device 1 provided by the present invention, according to the different usage situations of each user, the image capture device 30 captures the iris information of different users. The memory 402 stores and establishes a database of iris information of different users. After the processor 401 obtains the iris information of the user transmitted by the image capture device 30, it compares the obtained iris information with the iris information already stored in the iris database in the memory 402. If there is iris information in the iris database in the memory 402 that matches the current user, the processor 401 will obtain the iris data in the iris database that is consistent with the current user and identify the identification information of the current user. Especially in the scenario where a device is used by multiple people in a hospital, clinic or home, before the treatment starts, the user only needs to place the eye 10 in the correct usage position and turn on the medical device 1 to compare the iris data to automatically identify the user, which can effectively and conveniently distinguish users and avoid the confusion of user data.
[0066] The ophthalmic medical device 1 provided in this embodiment further includes a supplementary light unit 50, which is configured to provide light for the image capture device 30 to capture the user's eye 10. Specifically, the supplementary light unit 50 can be a device that provides an infrared light source, which is used to provide a well-lit shooting environment for the image capture device 30. When the user uses the ophthalmic medical device 1 provided by the present invention, the supplementary light unit 50 starts to work. The physiological characteristics of the iris reflect the near-infrared light beam, and the reflected light beam can be captured by the image capture device 30, so as to capture a clear iris image.
[0067] In the embodiment of the present invention, the processor 401 is configured to compare the iris information with the iris database. If the iris information is inconsistent with the iris data in the iris database, the memory 402 stores the iris information and establishes user identification information corresponding to the user. Further, after the image capture device 30 captures an image of the entire human eye, the processor 401 extracts the boundary features of the image, extracts the outer diameters of the iris circle and the pupil circle, segments the iris area, and then performs normalization processing to complete the collection of the iris. The processor 401 uses a specific algorithm to extract the feature points required for iris recognition from the iris image and encodes them in a specific manner, and matches the feature codes extracted with the iris image feature codes in the database to determine whether they are the same iris, so as to achieve the purpose of user identification, avoid the confusion of user usage data, and have good recognition stability, high accuracy, high security, and uniqueness.
[0068] After receiving the human eye iris information captured by the image capture device 30, the processing control unit 40 distributes it to the processor 401 and the memory 402. When different users use the ophthalmic medical device 1, due to the different situations of each user, the image capture device 30 captures the iris information of different users, and the memory 402 stores and establishes a database of iris information of different users. After the processor 401 obtains the user iris information transmitted by the image capture device 30, it compares the obtained iris information with the iris information already stored in the iris database in the memory 402. If there is no iris information in the iris database in the memory 402 that matches the current user, the memory 402 will re-establish an iris information and personal database that matches the user and store it in the database, which is used to record and collect personal usage reports, personal usage configuration parameters, and the user's historical usage situations. When the user uses the ophthalmic medical device 1 of the present invention again, after capturing the human eye iris data through the image capture device 30, the personal information that matches the user is retrieved from the iris database in the memory 402, and the device automatically matches the user configuration parameters stored in the database and adjusts them to the same state as the user's preference settings. Different users do not need to adjust the parameters of the device according to their personal situations again, so that the user can obtain a better and more convenient usage experience.
[0069] In an embodiment of the present invention, the memory 402 is further configured to store one or a combination of several of user historical usage data, user usage reports, and user configuration parameters associated with user identification information. The user configuration parameters at least include one or a combination of several of the output power of the light energy source 20, the user's pupil distance, and the treatment duration. Specifically, when the image capture device 30 recognizes the human eye and captures the iris information, the captured iris information is transmitted to the processing and control unit 40. The processing and control unit 40 sends the information to the memory 402. After the memory 402 recognizes the received information, it associates the user information and creates a personal database. The database information includes the data during the user's use and the recorded historical data, the user usage report generated based on the data, the personal configuration parameters when the user uses the device, and the combination of the above data, which is not limited here.
[0070] In a preferred embodiment of the present invention, the ophthalmic treatment device further includes a display unit 120. When the processor 401 obtains the user identification information, the display unit 120 displays the user configuration parameters of the user's last use. Specifically, when the image capture device 30 captures the human eye information and sends it to the processing and control unit 40, and the processing and control unit 40 sends the received information to the processor 401, after the processor 401 obtains the user's identity information, it sends the relevant configuration parameter information corresponding to the user identity to the display unit 120. The display unit 120 can display the configuration value information when the user last used the device. The user can know their usage situation or make appropriate adjustments according to the information displayed on the display unit 120.
[0071] In this embodiment, the medical device 1 provided by the present invention further includes a communication unit 130. The communication unit 130 is configured to transmit data wirelessly or wiredly with other devices. The communication unit 130 at least includes one or a combination of several of a mobile base station communication module, a Bluetooth communication module, and a wifi communication module. Specifically, the ophthalmic medical device 1 can realize the data interconnection or sharing function through methods such as base station communication. The user can understand their usage situation and personal trial report through the data shared by the communication module. The communication unit 130 is configured to transmit data wirelessly or wiredly with the communication unit 130 of another ophthalmic medical device 1 to realize data sharing, which can be applied to the usage scenario where a doctor remotely obtains the user's usage situation and other data in the hospital.
[0072] See Figure 5As shown, another embodiment of the present invention provides a method for real-time analysis of the effective power entering the eye of a medical device 1. The medical device 1 includes a light energy source 20, an image capture device 30, and a processing and control unit 40. At least part of the light emitted by the light energy source 20 is guided to the user's eye 10. Specifically, the image capture device 30 acquires information about the user's eye 10. When the user uses the ophthalmic medical device provided by the present invention, the two eyes are brought close to the ophthalmic medical device. There are multiple fill lights near the position of the human eye. The image capture device 30 can be an infrared camera, which can effectively capture the clear movement trajectories of the eyeball and pupil. When the image capture device 30 starts to work, the fill lights are activated and provide a good shooting environment for the image capture device 30, making the captured image clearly visible for real-time analysis of the user's eye-opening and eye-closing conditions. The image capture device 30 captures the human eye information by scanning the user's eye 10 from top to bottom; when the image capture unit captures the user's human eye information, it is transmitted to the processing and control unit 40, and the processing and control unit 40 calculates the received eye 10 information.
[0073] In this embodiment, after receiving the eye 10 information transmitted by the image capture device 30, the processing and control unit 40 analyzes the user's eye 10 information in real time during the user's use process and obtains the effective power entering the user's eye 10 from the light energy source 20; when the effective power entering the eye is greater than or equal to the set value, the processing and control unit 40 controls the power entering the eye, and the processing and control unit 40 controls the light to stop entering the user's eye 10, which can accurately control the treatment time of the light energy source irradiating the user's eye.
[0074] Furthermore, the user's eye 10 information includes at least one or a combination of several of the blink frequency, blink duration, the fixation point of the user's eye 10, whether the eyes are closed, the duration of eye closure, pupil size, and whether corrective glasses are worn. Specifically, the image capture device 30 captures the information of the user's two eyes, and the normal blinking of the user during use will also affect the treatment effect of the ophthalmic medical device 1.
[0075] Refer to Figure 6 , in a further embodiment, the processing and control unit 40 calculates the mapped area of the pupil on the plane perpendicular to the light direction according to the user's eye 10 information during the user's use process. The output power of the light energy source 20 is integrated with the mapped area and the use time and multiplied by the power coefficient to obtain the effective power entering the eye. When the user closes the eyes or the fixation point and the light energy source 20 are not at the same point, the light energy source 20 does ineffective work. The processing module calculates the user's eye closure time and the line-of-sight deviation duration through the received information. For example, refer to Figure 7 , when the user's pupil deflects to one side and does not directly face the light energy source 20, the mapped area of the pupil on the plane perpendicular to the light direction is shown as the black shaded part in the figure. Refer to Figure 8, when the user's pupil directly faces the light energy source 20, the mapped area of the pupil on the plane perpendicular to the light direction is shown as the black shaded part in the figure. Refer to Figure 9 , when the user's pupil deflects to the other side and does not directly face the light energy source 20, the mapped area of the pupil on the plane perpendicular to the light direction is shown as the black shaded part in the figure.
[0076] The processing control unit 40 includes a processor 401 and a memory 402. The memory 402 stores user usage reports or usage suggestions. Specifically, the memory 402 is electrically connected to the processor 401 and conducts data transmission through a transmission port. Further, when the user closes their eyes during the usage stage, the processor 401 can calculate the ineffective work time with closed eyes based on the transmitted information of the user's eyes 10, denoted as W c1 , when the image capture device 30 captures multiple pieces of information of the eyes 10 and transmits them to the processing control unit 40, the processor 401 calculates multiple ineffective work times based on the obtained information of the eyes 10 and denotes them as W c2 、W c3 ……W cX , and finally calculates the total ineffective work W with closed eyes c , when the calculation module calculates that the duration of closing eyes is greater than the set duration, such as 3 seconds, the system determines that the eyes are closed for a long time, and the ophthalmic medical device 1 will issue an alarm to remind the user and provide the user with correct usage guidance.
[0077] In a preferred embodiment, the ophthalmic medical device is provided with an eye movement tracking device such as a camera, and the eye movement tracking device determines the ineffective time during the treatment time. For example, the user's normal blinking, and the eye fixation point is not on the light energy source. To protect the eyes 10, the eyes 10 will instinctively blink to evenly moisten the cornea and conjunctiva with tears, keep the eyeball moist, maintain the luster of the cornea, and remove dust and bacteria in the conjunctival sac.
[0078] When the user's eyes directly face the light energy source, refer to Figure 8 As shown, the eye movement tracking device can analyze the light input amount into the user's pupil, the total number of blinks and the blink duration based on factors such as pupil size, blinking situation, and whether wearing vision correction devices, etc., to obtain the effective work W o and the ineffective work W on .
[0079] When the user's eyes do not directly face the light energy source, refer to Figure 7 and 9 As shown, the eye movement tracking device can analyze the light input amount into the user's pupil, the total number of blinks and the blink duration based on factors such as the mapped area of the pupil on the plane perpendicular to the light direction, blinking situation, and whether wearing vision correction devices, etc., to obtain the effective work W s and the ineffective work W sn, the effective total work actually entering the eye 10 by the light energy source 20 is W = W o +W s , to achieve an ideal therapeutic effect, the ophthalmic medical device 1 dynamically adjusts the illumination parameters according to the effective work and the ineffective work. Specifically, when it is calculated that the effective work W entering the eye is less than the set value matching the user, the illumination time of the light energy source 20 is extended or the output power of the light energy source 20 is increased to ensure the total effective work entering the eye, so as to better achieve the therapeutic effect. When it is calculated that the effective work W entering the eye is equal to the set value matching the user, the light energy source 20 stops outputting light. Compared with the prior art in which the treatment time is mechanically set to 3 minutes uniformly, it better meets the personalized needs of users and ensures a better therapeutic effect.
[0080] In this embodiment, after the user finishes using the ophthalmic medical device 1, the system will automatically generate a usage report for this period of time and send it to the user. The user usage report includes the user usage duration, the effective work and ineffective work of the light energy source 20 entering the eye, the standard usage duration and non-standard usage duration of the ophthalmic medical device 1. The non-standard usage duration includes the time when the eyes 10 are closed or squinted when the light source enters the eye, etc., when the light source is not irradiated on the fixation point.
[0081] Correspondingly, an embodiment of the present invention provides a medical device 1 for real-time analyzing the effective work entering the eye, including a light energy source 20, an image capture device 30, and a processing and control unit 40. At least part of the light rays emitted by the light energy source 20 are guided to the user's eye 10. The image capture device 30 is configured to acquire the user's eye 10 image and iris information. The user's eye 10 image and iris information are transmitted to the processing and control unit 40. The processing and control unit 40 obtains the user identity recognition information according to the iris information, calculates and obtains the matching output power of the light energy source 20 corresponding to the user identity recognition information according to the eye 10 image information, and controls the output power of the light energy source 20 to be adaptively adjusted to the matching output power.
[0082] Specifically, the light energy source 20 can be set as an LED light source or a laser light source, and the image capture device 30 is an invisible light camera (such as an infrared camera) or a visible light camera, which is used to clearly and stably capture the eye information image. When collecting iris information, the iris area is segmented by extracting the outer diameter features of the iris circle and the pupil circle in the captured eye image, thereby completing the collection of iris information. In addition, the medical device 1 of the present invention further includes a supplementary light unit 50, and the supplementary light unit 50 provides more suitable light for the image capture device 30 to photograph the user's eye 10. When the user uses the medical device 1 of the present invention, the light emitted by the light energy source 20 is transmitted to the user's eye 10. To ensure that different output optical powers are provided according to different needs of the user's eye 10 to obtain better treatment effects, the ophthalmic medical device 1 is provided with an image capture device 30 and a processing and control unit 40. The image capture device 30 captures the eye 10 information and iris information and transmits the user's eye 10 information and iris information to the processing and control unit 40. The processing unit calculates the output power matching the user, and controls the output power of the light energy source 20 to be adaptively adjusted to the matching output power to ensure that the user obtains the appropriate incident eye power for himself, which more meets the personalized needs of the user and ensures that the user obtains a better treatment effect.
[0083] The processing and control unit 40 can analyze the user's eye 10 information in real time during the user's use process through the transmitted user eye 10 image information and obtain the effective incident power of the light energy source 20 entering the user's eye 10, which is determined by the eye movement tracking device and / or the picture captured by the image capture device 30; when the calculated effective incident power is greater than or equal to the matching output power, the processing and control unit 40 controls the light energy source 20 to stop irradiating light into the user's eye 10, that is, when the output of the light energy source 20 meets the matching output power, the medical device 1 can automatically stop the treatment to ensure the user's use safety and personalized use needs.
[0084] The processing and control unit 40 includes a processor 401 and a memory 402. The memory 402 is configured to store an iris database corresponding to the user identity recognition information. The processor 401 is configured to compare the iris information with the iris database. If the iris information is consistent with the iris data in the iris database, the processor 401 obtains the user identity recognition information corresponding to the consistent iris data; if the iris information is inconsistent with the iris data in the iris database, the memory 402 stores the iris information and establishes the user identity recognition information corresponding to the user. After the medical device 1 of the present invention identifies the user identity recognition information currently in use, it further determines the matching output power suitable for the user.
[0085] Specifically, the processor 401 and the memory 402 are data-connected and transmit data to each other. When the user uses the ophthalmic medical device 1 provided by the present invention, after the user places the eye 10 at the designated treatment position (such as near the lens barrel), the image capture device 30 captures an image of the user's eye 10 to obtain relevant eye information and transmits it to the processor 401 and the memory 402. The processor 401 determines whether it matches the user information by comparing the iris information in the iris database in the memory 402. If the iris information is consistent, the processor 401 controller retrieves the user information in the memory 402 and adjusts the power of the light energy source 20 of the instrument to the matching output power corresponding to the user, meeting the needs of different users with different treatment powers in the usage scenario of sharing the same ophthalmic medical device, and being able to effectively and conveniently identify the user's identity, avoiding the confusion of the user's usage data.
[0086] Furthermore, the memory 402 is also configured to store one or a combination of several of the user's historical usage data, user usage reports, and user configuration parameters associated with the user identity recognition information. The user configuration parameters at least include one or a combination of several of the output power of the light energy source 20, the user's pupil distance, and the treatment duration. For example, the treatment requirements of each user's eye 10 are different, and the corresponding matching output power of the user's light energy source 20 is also different, or it is automatically adjusted to the pupil distance or treatment duration suitable for the user according to the identified different user pupil distance data.
[0087] Furthermore, the ophthalmic medical device 1 in the embodiment of the present invention further includes a position adjustment unit 110. The position adjustment unit 110 includes a micro-motor 111 and an adjustment bracket 112 connected to the output mechanism of the micro-motor 111. The light energy source 20 is disposed on the adjustment bracket 112, and the light energy source 20 can move in the up and down, left and right, or front and back directions under the drive of the micro-motor 111. After the user identity matches the iris information in the database, the adjustment bracket 112 adjusts the position of the light energy source 20 according to the needs of different users identified, such as automatically adjusting to the pupil distance required by the current user.
[0088] Furthermore, the ophthalmic medical device 1 further includes a display unit 120. The display unit 120 can be an LED display screen. After the processor 401 obtains the user identity recognition information, the user can view the user configuration parameters or usage reports of the user's last use through the LED display screen, and there is no limitation here. The light energy source 20 in this embodiment can be a controllable light source, and the wavelength and / or light intensity of the controllable light source can be adjusted. The controllable light source adjusts the light intensity according to the user pupil diameter information obtained by the image capture device 30.
[0089] Specifically, when a user uses the medical device 1 provided by the present invention, the image capture device 30 captures the human eye to obtain human eye information and transmits it to the processing and control unit 40, such as the pupil diameter. Further, the processing and control unit 40 dynamically adjusts the emission value of the light source according to the calculated pupil diameter. When the image capture device 30 captures a change in the human eye pupil, the processing and control unit 40 calculates the pupil diameter size again based on the captured image. If the calculation result is smaller than the pupil diameter size calculated from the previous capture, it is determined that the pupil has constricted. The processing and control unit 40 controls the light energy source 20 to increase the emitted light intensity, thereby improving the accuracy of the incident light intensity and ensuring that the total incident light intensity accumulation is a fixed value, making the clinical data more consistent. The image capture device 30 can be an invisible light camera (such as an infrared camera) or a visible light camera, and there is no limitation here.
[0090] Preferably, the ophthalmic medical device 1 further includes a communication unit 130. The communication unit 130 can wirelessly or wiredly transmit data to other devices through base station communication, Bluetooth communication, wifi communication, or combined communication. In this way, the user can export information such as their usage data and inspection reports to other devices, facilitating the user to view their treatment parameters and historical usage in real time. Of course, the communication unit 130 can also wirelessly or wiredly transmit data to the communication unit 130 of another ophthalmic medical device 1 to share data. Specifically, when the user replaces or adds ophthalmic medical equipment, there is no need to record the settings and parameters again, nor to worry about the loss of historical data. Through the transmission of the communication unit 130, data sharing and interconnection of two or more machines can be achieved.
[0091] Referring to Figure 10 , an embodiment of the present invention provides a method for adaptively adjusting the output power of the light energy source 20 of a medical device. The medical device 1 includes a light energy source 20, an image capture device 30, and a processing and control unit 40. At least part of the light emitted by the light energy source 20 is guided to the user's eye 10, and the method includes the following steps:
[0092] The image capture device 30 acquires an image of the user's eye 10 and iris information;
[0093] The image of the user's eye 10 and iris information are transmitted to the processing and control unit 40;
[0094] The processing and control unit 40 obtains the user identification information according to the iris information, calculates and obtains the matching output power of the light energy source 20 corresponding to the user identification information according to the image information of the eye 10, and controls the output power of the light energy source 20 to be adaptively adjusted to the matching output power, so that the user obtains a more optimized and suitable treatment effect for their own needs.
[0095] The medical device 1 of the present invention may be an ophthalmic medical device 1 such as a light-feeding device, and its processing control unit 40 includes a processor 401 and a memory 402. The memory 402 stores an iris database corresponding to user identification information. The processor 401 compares the iris information with the iris database. If the iris information is consistent with the iris data in the iris database, the processor 401 obtains the user identification information corresponding to the consistent iris data. If the iris information is inconsistent with the iris data in the iris database, the memory 402 stores the iris information and establishes the user identification information corresponding to the user.
[0096] In a preferred technical solution, the ophthalmic medical device 1 further includes a fill light unit 50, which is used to provide light for the image capture device 30 to capture the user's eyes 10. In addition, the ophthalmic medical device 1 may also include a reminder unit, and the image information of the eyes 10 acquired by the image capture device 30 can be used to analyze whether the user uses the device correctly. When it is determined that the user closes his eyes during use, the processor 401 sends a reminder signal to the reminder unit. The reminder unit includes but is not limited to a sound reminder unit and a vibration reminder unit, which are used to remind the user or his guardian to use the medical device 1 correctly.
[0097] The memory 402 is also configured to store one or a combination of user history usage data, user usage reports, and user configuration parameters associated with the user identification information. The user configuration parameters include at least one or a combination of the output power of the light energy source 20, the user's pupil distance, and the treatment duration.
[0098] The memory 402 also stores the preset safe output power of the light energy source 20, and the matching output power is less than or equal to the preset safe output power. The medical device 1 can match the safe output power according to the conditions of different users' eyes 10, so as to better meet the individual needs of the users and obtain better treatment effects, and avoid the accidental situation that the matching output power is greater than the preset safe output power, and the use safety is high.
[0099] See also Figure 11 As shown, an embodiment of the present invention provides a method for adaptively adjusting the position of a light energy source 20 of a medical device, wherein the medical device 1 comprises a light energy source 20, an image capturing device 30, a processing control unit 40 and a position adjusting unit 110, and at least part of the light emitted by the light energy source 20 is guided to the user's eye 10, comprising the following steps:
[0100] The image capture device 30 obtains the user's eye position information by taking real-time photos and transmits the position information of the user's eye 10 to the processing and control unit 40; the processing and control unit 40 calculates and obtains the relative position data of the user's eye 10 with respect to the reference coordinate system of the medical device 1 based on the position information of the user's eye 10, and the processing and control unit 40 controls the position adjustment unit 110 to adjust the light energy source 20 to the corresponding position where the light enters the user's eye 10 correctly according to the relative position data. Specifically, the image capture device 30 can also obtain the iris information of the user's eye 10 by photographing the human eye information, and the processing and control unit 40 processes the iris information to obtain the user identification information.
[0101] As Figure 12 shown, the processing and control unit 40 calculates and obtains the relative position data of the user's eye 10 with respect to the reference coordinate system of the ophthalmic medical device 1 based on the position information of the user's eye 10 photographed by the image capture device 30, and the processing and control unit 40 controls the position adjustment unit 110 to adjust the light energy source 20 to the corresponding position where the light enters the user's eye 10 correctly according to the relative position data. Specifically, as shown in the figure, taking the center of the eyepiece 101 as the coordinate origin, the processing and control unit 40 calculates the known coordinates (A, B) of the user's pupil in the image through the image photographed by the image capture device 30, and the known focal length of the image capture device 30 is d f , the known position of the image capture device 30 from the user's eye 10 is d1, and the position coordinates of the pupil can be located by calculation as (x, y), where x = A * d1 / d f , y = B * d1 / d f . The processing and control unit 40 adjusts the light energy source 20 to emit light directly at the pupil position of the user according to the calculated position coordinates of the user's pupil. When the user's eye 10 moves left and right, the image capture device 30 captures the real-time position of the eye 10 in real time, and the processing and control unit 40 analyzes two new pupil coordinate positions through the real-time positions of the left and right eye pupils obtained, and then adjusts the position of the light energy source 20 to achieve real-time tracking of the pupil during the user's use, so as to achieve the optimal treatment effect.
[0102] In an embodiment of the present invention, referring to Figure 13 , when the user is a child, since the distance between the pupils of both eyes is relatively close, after the ophthalmic medical device 1 calculates the coordinate positions of the pupils, the position adjustment unit 110 automatically adjusts the positions of the two light energy sources 20 to the positions facing the user's eyes accordingly. Referring to Figure 14When the user is an adult and the distance between the pupils of both eyes is relatively far, the ophthalmic medical device 1 automatically adjusts the positions of the two light energy sources 20 to the positions directly facing the user's eyes according to the calculated coordinate positions of the pupils by the position adjustment unit 110. Especially when multiple people share one ophthalmic medical device 1, it can be more simply and automatically adjusted to the treatment position required by the user to ensure better treatment effects.
[0103] The processing and control unit 40 includes a processor 401 and a memory 402. The controller and the memory 402 are data-connected and transmit data to each other. The memory 402 stores an iris database corresponding to the user identification information. The processor 401 compares the iris information with the iris database. If the iris information is inconsistent with the iris data in the iris database, the memory 402 stores the iris information and establishes user identification information corresponding to the user. Specifically, after the user has used the ophthalmic medical device 1, the memory 402 newly creates and stores the user data information in the memory 402. When a new user uses the ophthalmic medical device 1, through iris photography comparison, if the corresponding iris information is not matched in the memory 402, the memory 402 newly creates and stores the user identification information corresponding to the new user.
[0104] When the user uses the ophthalmic medical device 1 provided by the present invention, when the user brings the human eye close to the eyepiece 101, the image capture device 30 captures the user's human eye information through the lens barrel and transmits it to the controller and the memory 402. The processor 401 determines whether it matches the user information by comparing the iris information in the iris database in the memory 402. If the iris information is consistent, the processor 401 controls the controller to retrieve the user information in the memory 402 and automatically adjusts the position of the light energy source 20 of the ophthalmic medical device 1 to the position corresponding to the user, thereby solving the problem that different users cannot use the same ophthalmic medical device simultaneously due to different pupil positions.
[0105] In this embodiment, the ophthalmic medical device 1 further includes a supplementary light unit 50, and the supplementary light unit 50 provides light for the image capture device 30 to photograph the user's eyes 10. Specifically, the supplementary light unit 50 is arranged inside the ophthalmic medical device 1, and the light supplemented by the supplementary light unit 50 can be infrared light. When the user uses the ophthalmic medical device, the supplementary light unit 50 starts to work, and the physiological characteristics of the iris of the user's eyes 10 reflect the infrared light beam, and the iris image information of the user can be clearly captured in cooperation with the image capture device 30.
[0106] Further, the memory 402 is further configured to store one or a combination of user historical usage data, user usage reports, and user configuration parameters associated with user identification information. Specifically, the user configuration parameters include the output power of the light energy source 20 when different users use it. Since the usage conditions of each user are different, the corresponding output power is also different. Data such as the pupillary distance and treatment duration of different users are matched according to the usage parameters of different users. The memory 402 also stores a preset safe output power of the light energy source 20. The matched output power is less than or equal to the preset safe output power. The memory 402 performs safe output power matching for different users. According to different personal conditions, such as using a constant output power, it can prevent damage to the eyes 10 caused by excessive output power for users with different conditions or failure to achieve the expected treatment effect due to too low output power.
[0107] In an embodiment of the present invention, a medical device 1 with an adaptive adjustment of the position of the light energy source 20 is provided, including a light energy source 20, an image capture device 30, a processing and control unit 40, and a position adjustment unit 110. At least part of the light emitted by the light energy source 20 is guided to the user's eyes 10. The image capture device 30 is configured to obtain the position information of the user's eyes 10. The position information of the user's eyes 10 is transmitted to the processing and control unit 40. The processing and control unit 40 calculates and obtains the relative position data between the user's eyes 10 and the reference coordinate system of the medical device 1 according to the position information of the user's eyes 10. The processing and control unit 40 controls the position adjustment unit 110 to adjust the light energy source 20 to the corresponding position where the light enters the user's eyes 10 correctly according to the relative position data. In this embodiment, the position adjustment unit 110 includes a micro-motor 111 and an adjustment frame 112 connected to the output mechanism of the micro-motor 111. The light energy source 20 is arranged on the adjustment frame 112. The light energy source 20 can move in the left-right direction and the up-down direction under the drive of the micro-motor 111 in the reference coordinate system.
[0108] In a further technical solution, the image capture device 30 also obtains the iris information of the user's eyes 10. The processing and control unit 40 processes the iris information to obtain user identification information. The processing and control unit 40 includes a processor 401 and a memory 402. The memory 402 stores an iris database corresponding to the user identification information. The processor 401 compares the iris information with the iris database. If the iris information is consistent with the iris data in the iris database, the processor 401 obtains the user identification information corresponding to the consistent iris data. If the iris information is inconsistent with the iris data in the iris database, the memory 402 stores the iris information and establishes the user identification information corresponding to the user.
[0109] When a user uses the ophthalmic medical device 1 of the present invention to treat ophthalmic diseases such as myopia, the image capture device 30 takes pictures of the user's eye information. After the user's identity matches the iris information in the database, the adjustment frame 112 automatically adjusts the position of the light energy source 20 according to the pupil position after the user's last use. Especially when multiple people share a machine in a hospital, it can automatically and quickly adjust the light energy source 20 to a position suitable for the user's interpupillary distance, which is particularly convenient for younger users.
[0110] Further, the light energy source 20 is an LED light source or a laser light source. At least part of the emitted light is guided to the user's eye 10 to irradiate energy light waves into the user's eye 10, providing light energy for the user's eye 10 to supplement red light of a specific wavelength, improving the blood circulation in the fundus of the eye and thickening the choroid nutrition, so as to achieve the purpose of controlling the growth of the eye axis and preventing and controlling myopia. The image capture device 30 is an invisible light camera or a visible light camera, which is used to clearly and stably capture the image of the human eye information. Then, through the convenient feature extraction of the image, the iris region is segmented according to the outer diameters of the iris circle and the pupil circle, thus completing the iris collection.
[0111] Further, the ophthalmic medical device 1 further includes a position adjustment unit 110. The position adjustment unit 110 includes a micro-motor 111 for detecting the electrical signal and the light source output power, and an adjustment frame 112 connected to the output mechanism of the micro-motor 111. The light energy source 20 is arranged on the adjustment frame 112. After the user's identity matches the iris information in the database, the adjustment frame 112 adjusts the position of the light energy source 20 according to the position after the user's last use. The light energy source 20 can move in the left-right direction and the up-down direction under the drive of the micro-motor 111.
[0112] Further, the device further includes a display unit 120. The display unit 120 can be an LED display screen. After the processor 401 obtains the user identity information through iris recognition, the display unit 120 displays the user configuration parameters of the user's last use, and the adjustment device automatically adjusts the light energy source 20 to the position of the user's last use, which is not limited here.
[0113] Preferably, the ophthalmic medical device 1 further includes a communication unit 130. The communication unit 130 can wirelessly or wiredly transmit data to other devices through base station communication, Bluetooth communication, Wi-Fi communication, or combined communication. In this way, the user can export information such as their usage data and inspection reports to other devices, facilitating the user to view their treatment parameters and conditions in real time. Of course, the communication unit 130 can also wirelessly or wiredly transmit data with the communication unit 130 of another ophthalmic medical device 1 to share data. Specifically, when the user replaces or adds ophthalmic medical equipment, there is no need to record the settings, configurations, and parameters again, nor to worry about the loss of historical data. Through the transmission of the communication unit 130, data sharing and interconnection between the two machines can be achieved.
[0114] See Figure 3 With Figure 15 As shown, another embodiment of the present invention provides an ophthalmic medical device 1 with a replaceable human contact component 150, which at least includes a light energy source 20, a first communication component 160, a processing and control unit 40, and a human contact component 150 detachably connected to the ophthalmic medical device 1; at least part of the light emitted by the light energy source 20 is guided to the user's eye 10, and the human contact component 150 is configured with identity recognition information that can be recognized by the ophthalmic medical device 1. The human contact component includes a second communication component 140, and the second communication component 140 is configured to transmit the user identity recognition information to and from the first communication component 160 in a wired or wireless manner. Compared with the prior art, since the human contact component 150 (such as the eye mask in contact with the user's eye 10 on the optometry instrument) is detachably connected to the ophthalmic medical device 1, it can be sold separately for exclusive use by the user. Especially when multiple people share an ophthalmic medical device in a hospital, the user only needs to install their own human contact component 150 to automatically identify the user, and it can effectively avoid cross-infection, ensuring safety and hygiene.
[0115] Specifically, the first communication component 160 / second communication component 140 may be a near-field communication module, a bar code communication module, or an electrical connection communication module. The near-field communication module includes at least one of a WIFI communication module, a radio frequency identification (RFID) communication module, an NFC near-field communication module, a Bluetooth communication module, a Zigbee wireless personal area network communication module, a wireless communication module with a set frequency band (such as 433 MHz), a magnetic field communication module, and an acousto-magnetic communication module. The bar code communication module may include a one-dimensional code (such as code 128, EAN for product barcodes, and UPC for universal product codes), and a two-dimensional code (such as Data Matrix and QR code). The user identification information contained in the one-dimensional code or two-dimensional code can be read by the image capture device 30 in the ophthalmic medical device 1. The electrical connection communication module may include at least two electrical contacts that can be electrically connected to the ophthalmic medical device 1, and information related to user identification is transmitted through the on / off signals of the electrical contacts.
[0116] At least part of the light rays emitted by the light energy source 20 are guided to the user's eye 10. The light energy source 20 is an LED light source or a laser light source, which is used to irradiate energy light waves into the user's eye 10 to provide light energy supplementation with a specific wavelength for the user's retina. For example, it can be used to treat juvenile myopia or amblyopia. Refer to Figure 16 In a specific embodiment of the present invention, an NFC near-field communication module is provided in the human body contact component 150. Each user can be equipped with their own dedicated human body contact component 150 and bind the information of their unique user, such as a unique serial number or product number. When the human body contact component 150 is connected to the ophthalmic medical device 1, the NFC near-field communication module transmits the unique serial number for identifying the user to the first communication component 160 of the ophthalmic medical device 1, so that the ophthalmic medical device 1 obtains the identification information and transmits it to the processing and control unit 40. The processing and control unit 40 of the ophthalmic medical device 1 can obtain the user identification information according to the identification information, and provide a further optimized treatment plan according to the user's usage situation or the condition of the eye 10 to meet the different treatment needs of the user.
[0117] Further, when the replaceable human body contact component 150 is installed on the ophthalmic medical device 1, the first communication component 160 on the ophthalmic medical device 1 can also identify the relevant configuration information preset by the user in the replaceable human body contact component 150 through the NFC near-field communication module, and automatically match the corresponding output parameters of the ophthalmic medical device 1 according to the user configuration information, intelligently identify the user, and automatically adjust the parameters to achieve plug-and-play.
[0118] In this embodiment, the processing control unit 40 includes a processor 401 and a memory 402. The memory 402 is configured to store an identity information database corresponding to the user identity information, and store one or a combination of several of the user's historical usage data, user usage reports, and user configuration parameters associated with the user identity information. The user configuration parameters at least include one or a combination of several of the output power of the light energy source 20, the user's pupil distance, the treatment duration, and the remaining treatment times.
[0119] When the ophthalmic medical device 1 acquires the user identity information, the processor 401 is configured to compare the identity information with the identity information database preset in the memory 402. If the identity information is consistent with the data in the identity information database, the processor 401 acquires the user identity information corresponding to the consistent identity information. Specifically, the processor 401 and the memory 402 are connected by data and transmit data to each other. When the user first uses the ophthalmic medical device 1 provided by the present invention, the parameters of the user's first use (such as the output power of the light energy source 20, the user's pupil distance, the treatment duration, and the remaining treatment times) can be stored in the memory 402; when the user uses it again, the user only needs to connect the replaceable human contact part 150 to the ophthalmic medical device 1, and the near-field communication NFC module on the human contact part 150 and the identification unit on the ophthalmic medical device 1 realize near-field communication data transmission. After the processor 401 acquires the identity information bound to the user and confirms the user identity information, it can automatically retrieve the user configuration parameters of the previous use that match the user, such as the output power of the light energy source 20, the user's pupil distance, the treatment duration, and the remaining treatment times.
[0120] The ophthalmic medical device 1 further includes a display unit 120. The display unit 120 can be an LED display screen. When the processor 401 acquires the user identity information, the display unit 120 displays the user configuration parameters of the user's previous use. The user can control the machine operation parameters of the ophthalmic medical device 1 by means of physical buttons or touch screens on the display unit 120. Specifically, the operation parameters include whether to operate the ophthalmic medical device 1, the operation duration of using the ophthalmic medical device 1, the spatial distance between the light source and the human eye when the user is using, and adjusting the output power of the light energy source 20 according to the user's own situation during operation.
[0121] In this embodiment, one end of the replaceable human contact component 150 that contacts the human body is made of silica gel or other soft materials, providing a more comfortable experience for users when using the ophthalmic medical device 1; the other end of the human contact component 150 is mated with the ophthalmic medical device 1. In a possible implementation manner, the human contact component 150 has a guiding structure when mated with the ophthalmic medical device 1. For example, the human contact component 150 can be guided through a chute fit, an overall shape fit, or other common guiding structures. In this embodiment, the human contact component 150 is positioned and mated with the ophthalmic medical device 1 by magnetic attraction. In other alternative embodiments, the mating and positioning method can also be achieved by bump buckles or other buckle methods, which are not limited herein.
[0122] Furthermore, the replaceable human contact component 150 includes a heating element and / or a refrigerating element, allowing users to set according to their preferences when using the ophthalmic medical device 1 of the present invention and providing a better experience for users.
[0123] Furthermore, the ophthalmic medical device 1 further includes an image capture device 30. The image capture device 30 is an invisible light camera or a visible light camera. The image capture device 30 obtains the position information of the pupil of the user's eye 10 by taking real-time pictures of the user's eye 10, and records the pupil information of the user and transmits it to the processing and control unit 40. The processing unit records the real-time position of the user's pupil according to the transmitted information and updates the user's usage information.
[0124] Furthermore, the ophthalmic medical device 1 further includes a supplementary light unit 50. The supplementary light unit 50 is arranged inside the ophthalmic medical device 1 and is used to provide light when the image capture device 30 takes pictures of the user's eye 10, so that the captured information of the user's eye 10 is complete and clear.
[0125] In this embodiment, preferably, the ophthalmic medical device 1 further includes a communication unit 130. The communication unit 130 can wirelessly or wirelesly transmit data to other devices through base station communication, Bluetooth communication, Wi-Fi communication, or combined communication. Users can import or export their usage data, inspection reports, and other information to other devices in this way, facilitating users to view their treatment parameters and conditions in real time. Of course, the communication unit 130 can also wirelessly or wirelesly transmit data with the communication unit 130 of another ophthalmic medical device 1 to share data. Specifically, when users replace or add ophthalmic medical equipment, there is no need to record the settings, configurations, and parameters again, nor to worry about the loss of historical data. Just through the transmission between the communication units 130 of the two ophthalmic medical devices, the data sharing and interconnection of the two machines can be achieved.
[0126] A replaceable human contact component 150 for an ophthalmic medical device 1 of the present invention, the human contact component 150 is detachably connected to the ophthalmic medical device 1, and the human contact component 150 is configured to have identification information that can be recognized by the ophthalmic medical device 1. When the human contact component 150 is connected to the ophthalmic medical device 1, the identification information is recognized by the ophthalmic medical device 1 to obtain user identification information. The human contact component 150 includes a second communication component 140, and the second communication component 140 is configured to communicate with the second communication component 160 of the ophthalmic medical device 1 in a wired or wireless manner. Refer to Figure 16 , in a preferred embodiment, the communication component 140 is a near-field communication NFC module. When the human contact component 150 is connected to the ophthalmic medical device 1, the unique device information transmits the identification information to the ophthalmic medical device 1 through wireless communication. Compared with the prior art, since the human contact component 150 (such as the eye mask in contact with the user's eye 10 on the optokinetic instrument) is detachably connected to the ophthalmic medical device 1, it can be sold separately for exclusive use by the user. Especially when multiple people share an ophthalmic medical device in a hospital, the user only needs to install his own human contact component 150 to automatically identify the user, and can effectively avoid cross-infection, safety and hygiene.
[0127] Specifically, the ophthalmic medical device 1 that can be connected to the human contact component 150 can be an optokinetic instrument, including a light energy source 20, a first communication component 160, and a processing and control unit 40. At least part of the light emitted by the light energy source 20 is guided to the user's eye 10. The first communication component 160 is used to receive the identification information and transmit it to the processing and control unit 40. The processing and control unit 40 is configured to process the identification information to obtain the user identity. In a specific embodiment of the present invention, when the user's human contact component 150 (such as the eye mask in contact with the user's eye socket) is adaptively connected to the optokinetic instrument, the processing and control unit 40 controls the operating parameters of the ophthalmic medical device 1 according to the user identification information. The operating parameters at least include whether the medical device 1 operates, the operating duration, the spatial distance of the light energy source 20 during operation, and the output power of the light energy source 20 during operation.
