Description

A method and device for adaptively adjusting the output power of a medical device optical energy source

Technical Field

The invention relates to a method and a device for adaptively adjusting the position of a light energy source of a medical device.

Background technique

The light energy source achieves a medical or health-care effect on the eyes by emitting light of a preset wavelength range to the eyes. In practical applications, the light energy source can be used for myopia, amblyopia, macular degeneration (AMD), diabetic retinopathy, glaucoma and other eye diseases. As the incidence of myopia among young people in my country increases year by year, taking the myopia of patients with medical or health-care myopia as an example, studies have shown that when the wavelength of the laser emitted by the light energy source is preset to be within the laser wavelength range that can be used for medical or health-care 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.

The output power of the light energy source of the existing device for treating ophthalmic diseases by irradiating the retina with light is usually constant.

Detailed ways

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

As shown in FIG1 , in one 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 control unit 40. At least part of the light emitted by the light energy source 20 is directed to the user's eye 10. The image capture device 30 is configured to obtain eye image information. The processing control unit 40 processes the eye image information to obtain information related to the user's usage. The medical device 1 of the present invention can be used to treat, but is not limited to, myopia, amblyopia, macular degeneration (AMD), diabetic retinopathy, glaucoma, and other eye diseases.

Specifically, taking the case where a user uses a medical device of the present invention that applies light energy to the eye to treat myopia as an example, the image capture device 30 obtains the eye image information and transmits it to the processing control unit 40. After receiving the information transmitted by the image capture device 30, the processing control unit 40 calculates and obtains the relevant information about the user's eye usage. Further, the user usage information includes at least one or more combinations of information about whether the user opens his eyes and uses it correctly, information about the user's pupil diameter, information about the user's pupil gaze angle, information about the position of the user's pupil, information for identifying the user, information about the user's effective use time, information about the total light power received by the user's eye 10, and information about the user's pupil distance, that is, the algorithm is used to correct the user's irregular use, such as closing the eyes, to ensure the therapeutic effect of the user's use process.

In one embodiment of the present invention, the medical device for applying light energy to the eye also includes a light distribution component 60 and a light detector 80 for detecting light intensity. The light distribution component 60 guides at least a portion of the light emitted by the light energy source 20 to the light detector 80 to detect the intensity of the emitted light emitted by the light energy source. The light distribution component 60 guides another portion of the light 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.

Further, when the user uses a medical device that applies light energy to the eye, the light energy source 20 is an LED light source or a laser light source. The LED light source or the laser light source emits a light wave, and a part of the light wave is received by the light detector 80 through the light distributor. The light distributor receives another part of the light wave emitted by the light energy source 20 by the user's eye 10, and the light reflected by the eye 10 is reflected on the image capture device 30 through the light distribution component 60.

Furthermore, 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, and the memory 402 is configured to store a correspondence table between 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, and the processor sends a signal to adjust the light intensity of the controllable light source according to the received emission light intensity, eye image information and the correspondence table.

Specifically, the eye image information includes at least 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, and the processing control unit 40 adjusts the light intensity of the controllable light source according to the emission light intensity, the user's pupil diameter information and the correspondence table received in real time. For example, when the pupil diameter captured by the image capture device 30 is reduced, the processor 401 can send a signal to the controllable light source to fine-tune and increase the emission light intensity.

Specifically, the light distributor may be a beam splitter, which is used to split the emitted light source into two beams of light, one reflected downward and one directed to the left. The beam splitting ratio of the beam splitter may be set by the manufacturer. For example, the beam splitter may direct 50% of the light emitted by the light energy source 20 into the user's eyes 10, and direct the other 50% of the light emitted by the light energy source 20 into the light detector 80, so that the light detector 80 can accurately detect the light power emitted by the light energy source 20.

As shown in FIG2 , in a preferred embodiment, at least one filter element 70 is disposed 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 may be a bandpass filter, a low-pass filter, or a high-pass filter. In this embodiment, a bandpass filter is disposed between the light energy source 20 and the light distribution component 60. When the light energy source 20 emits a light wave, the light wave passes through the bandpass filter to purify the wavelength. Further, for example, the wavelength of light emitted by the light energy source 20 is between 650 and 680 nm. When the light wave emitted by the light energy source 20 passes through the bandpass filter, the wavelength with a wider half-peak width can be reduced to a wavelength range with a narrower half-peak width.

When the light waves emitted by the light energy source 20 pass through the bandpass filter between the light energy source 20 and the light distribution component 60, in order to prevent the remaining stray light from being reflected to the image capture device 30, thereby affecting the shooting of the image capture device 30, a low-pass or high-pass filter is set 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 prompts in the image, so that the image capture device 30 will not exceed the reasonable dynamic range due to excessive light intensity, thereby ensuring the safety of user use.

In this embodiment, a bandpass filter similar to that between the optical energy source 20 and the optical distribution component 60 is arranged between the optical distribution component 60 and the optical detector 80. Similarly, when the optical energy source 20 emits laser light and passes through the optical distribution component 60 to reach the optical detector 80, it is used to block stray light in the light wave, thereby ensuring the accuracy of the measurement of the optical detector 80. By accurately detecting the intensity of light entering the eye and the state of the eyeball, the closed-loop monitoring of the light intensity output of the optical energy source 20 is truly realized, thereby improving the safety and reliability of the use of the medical device of the present invention.

At least one collimating element 90 for focusing the light emitted by the light energy source is arranged 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 are irradiated on the light splitting accessory through the collimating element 90, and the light waves emitted by the light energy source 20 are converted into parallel light through the collimating element 90, so that the light source is shortened to a parallel light spot with a diameter of about 10 mm covering the human eye, thereby ensuring the stability of the light source.

In this embodiment, at least one focusing element 100 is arranged between the image capture device 30 and the light distribution component 60. The focusing element 100 is used to adjust the appropriate detection focus. When the image capture device 30 captures the user's eye information, in order to ensure that the detection image of the captured eye position is the clearest, the focusing element 100 is arranged in front of the image capture device 30, so that the image capture 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 that applies light energy to the eye is greatly reduced, and the overall structure can be made lighter and more convenient for users, especially young users.

In a preferred embodiment, the present invention also includes a thermostat 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 wider output working range and detection accuracy, the thermostat can be controlled 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 thermostat to start working and keeps the working environment temperature constant at 25°C. The thermostat can be a TEC refrigeration plate, a compressor, etc.

In the calibration stage before the ophthalmic medical device 1 of the present invention is used, a calibration curve can be made for the light energy source 20 and the light detector 80 by using a metrologically certified device for testing on the user's eyes. In the subsequent actual use by the user, 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 of the controllable light source according to the user's pupil diameter information obtained by the image capture device 30.

Specifically, when the user uses the medical device 1 provided by the present invention, the image capture device 30 obtains information about the human eye 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. When the image capture device 30 photographs changes in the pupil of the human eye, the processing control unit 40 calculates the pupil diameter again according to the photographed image. If the calculated result is less than the pupil diameter calculated by the previous photograph, it is determined that the pupil is constricted. The processing control unit 40 controls the light energy source 20 to enhance the emission light intensity, thereby improving the accuracy of the light intensity entering the eye, ensuring that the accumulation of the entire light intensity entering the eye is a fixed value, so that the clinical data is more consistent. The image capture device 30 is an invisible light camera (such as an infrared camera) or a visible light camera, which is not limited here.

3 and 4, in another embodiment of the present invention, an ophthalmic medical device 1 with a user identification function includes a light energy source 20, an image capture device 30 and a processing control unit 40, and at least part of the light emitted by the light energy source 20 is directed to the user's eyes 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 lens barrels of the medical device 1. The image capture device 30 in this embodiment is configured to obtain iris information of the user's eyes 10, and the processing 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 eyes 10 by shooting, and the image capture device 30 obtains the iris information of the user's eyes 10 and transmits the obtained information to the processing control unit 40. The processing control unit 40 calculates and obtains the user's identification information based on the obtained user iris information. The processing control unit 40 can control the light energy to output different user configuration parameters for different users, such as different output powers of the light energy source 20 corresponding to different users.

In this embodiment, the processing control unit 40 includes a processor 401 and a memory 402. The memory 402 is configured to store an iris database corresponding to 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.

Furthermore, after receiving the iris information of the human eye 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 provided by the present invention, according to the different usage 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 the 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 stored in the iris database in the memory 402. If there is iris information matching the current user in the iris database in the memory 402, the processor 401 will obtain the iris data consistent with the current user in the iris database and identify the identity information of the current user. In particular, when a device is used by multiple people in a hospital, clinic or family, before the treatment begins, the user only needs to place the eye 10 in the correct use position, and the medical device 1 can be turned on and adjusted to compare the iris data to automatically identify the user, which can effectively and conveniently distinguish users and avoid confusion of user data.

The ophthalmic medical device 1 provided in this embodiment further includes a fill light unit 50, which is configured to provide light for the image capture device 30 to capture the user's eyes 10. Specifically, the fill light unit 50 may be a device that provides an infrared light source, and 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 fill light unit 50 starts to work, and the physiological characteristics of the iris reflect the near-infrared light beam, and the image capture device 30 can capture the reflected light beam, thereby capturing a clear iris image.

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 the user identification information corresponding to the user. Further, after the image capture device 30 captures a whole image of the human eye, the processor 401 extracts the boundary features of the image and extracts the outer diameters of the iris circle and the pupil circle to segment the iris area, and then performs normalization after segmentation, thereby completing the iris acquisition. The processor 401 uses a specific algorithm to extract the feature points required for iris recognition from the iris image and encode them in a specific way, matches the feature code extracted from the feature with the iris image feature code in the database, and determines whether they are the same iris, thereby achieving the purpose of user identification, avoiding confusion of user usage data, and having good identification stability, high accuracy, high security, and uniqueness.

After receiving the iris information of the human eye 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 present 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 the iris information of different users. After the processor 401 obtains the user iris information transmitted by the image capture device 30, the iris information obtained is compared with the iris information stored in the iris database in the memory 402. If there is no iris information matching the current user in the iris database in the memory 402, the memory 402 stores the iris information of the user. The device 402 will re-establish an iris information and personal database matching the user and store it in the database, which is used to record and compile personal usage reports, personal usage configuration parameters and the user's historical usage. When the user uses the ophthalmic medical device 1 of the present invention again, after capturing the iris data of the human eye through the image capture device 30, the personal information matching the user is retrieved from the iris database in the memory 402. The device automatically matches the user configuration parameters stored in the database and adjusts them to the same state as the user's preferred settings. Different users do not need to adjust the parameters of the device again according to their personal circumstances, so that users can obtain a better and more convenient usage experience.

In an embodiment of the present invention, the memory 402 is also configured to store one or a combination of user historical usage data, user usage reports, and user configuration parameters associated with user identity 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. 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 control unit 40, and the processing 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 new personal database. The database information includes the data and historical data recorded when the user uses it, 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 are not limited here.

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 used by the user last time. Specifically, when the image capture device 30 captures the human eye information and sends it to the processing control unit 40, and the processing control unit 40 sends the received information to the processor 401, the processor 401 obtains the user's identity information and sends the obtained relevant configuration parameter information corresponding to the user's 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 his or her usage or make appropriate adjustments based on the information displayed on the display unit 120.

In this embodiment, the medical device 1 provided by the present invention also includes a communication unit 130, and the communication unit 130 is configured to transmit data wirelessly or wired with other devices. The communication unit 130 includes at least one or a combination of a mobile base station communication module, a Bluetooth communication module, and a wifi communication module. Specifically, the ophthalmic medical device 1 can realize data interconnection or sharing functions through base station communication and other methods. Users can understand their usage status and personal trial reports through the data shared by the communication module. The communication unit 130 is configured to transmit data wirelessly or wired with the communication unit 130 of another ophthalmic medical device 1 to realize shared data, which can be applied to the use scenario where doctors remotely obtain user usage data and other data in the hospital.

As shown in FIG5 , another embodiment of the present invention provides a method for real-time analysis of the effective work of 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 control unit 40. At least part of the light emitted by the light energy source 20 is directed to the user's eye 10. Specifically, the image capture device 30 obtains information about the user's eye 10. When the user uses the ophthalmic medical device provided by the present invention, the user places both eyes close to the ophthalmic medical device. A plurality of fill lights are provided near the human eye. The image capture device 30 may be an infrared camera, which can effectively capture clear eyeball and pupil movement trajectories. When the image capture device 30 starts working, the fill light starts and provides a good shooting environment for the image capture device 30, so that the captured image is clear and visible, which facilitates real-time analysis of the user's eye opening and closing. The image capture device 30 scans the user's eye 10 from top to bottom to capture human eye information; after the image capture unit captures the user's human eye information, it is transmitted to the processing control unit 40, and the processing control unit 40 calculates the received eye 10 information.

In this embodiment, after the processing and control unit 40 receives the eye 10 information transmitted by the image capture device 30, it analyzes the user's eye 10 information in real time during the user's use and obtains the effective eye power of the light energy source 20 entering the user's eye 10; when the effective eye power is greater than or equal to the set value, the processing and control unit 40 controls the eye power, and the processing and control unit 40 controls the light to stop entering the user's eye 10, so as to accurately control the treatment time of the light energy source irradiating the user's eye.

Further, the user's eye 10 information includes at least one or a combination of blinking frequency, blinking duration, gaze point of the user's eye 10, whether the eyes are closed, how long the eyes are closed, pupil size, and whether corrective glasses are worn. Specifically, the image capture device 30 captures information about the user's eyes, and the user's normal blinking during use will also affect the treatment effect of the ophthalmic medical device 1.

Referring to FIG6, in a further embodiment, the processing control unit 40 calculates the mapping area of the pupil on the plane perpendicular to the light direction according to the information of the user's eyes 10 during the user's use, and the output power of the light energy source 20 is multiplied by the power coefficient to obtain the effective work of entering the eye. When the user closes his eyes or the gaze point and the light energy source 20 are not at the same point, the light energy source 20 does invalid work, and the processing module calculates the user's eye closing time and the duration of the line of sight deviation through the received information. For example, referring to FIG7, when the user's pupil deflects to one side and does not look directly at the light energy source 20, the mapping area of the pupil on the plane perpendicular to the light direction is shown in the black shaded part in the figure. Referring to FIG8, when the user's pupil looks directly at the light energy source 20, the mapping area of the pupil on the plane perpendicular to the light direction is shown in the black shaded part in the figure. Referring to FIG9, when the user's pupil deflects to the other side and does not look directly at the light energy source 20, the mapping area of the pupil on the plane perpendicular to the light direction is shown in the black shaded part in the figure.

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 transmits data through the transmission port. Further, when the user closes his eyes during the use phase, the processor 401 can calculate the eye-closing ineffective work time based on the transmitted user eye 10 information, which is recorded as W _c1 . When the image capture device 30 captures multiple eye 10 information and transmits it to the processing control unit 40, the processor 401 calculates multiple ineffective work times based on the obtained eye 10 information and records them as W _c2 , W _c3 ...... W _cx , and finally calculates the total eye-closing ineffective work W _c . When the calculation module calculates that the eye-closing time is greater than the set time, 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.

In a preferred embodiment, the ophthalmic medical device is provided with an eye tracking device such as a camera, and the eye tracking device determines the invalid time during the treatment time, such as the user's normal blinking and the eye gaze point not being on the light energy source. In order to protect the eye 10, the eye 10 will instinctively blink to evenly wet the cornea and conjunctiva with tears, keep the eyeball moist, maintain the corneal luster, and remove dust and bacteria from the conjunctival sac.

When the user's eyes look directly at the light energy source, as shown in Figure 8, the eye tracking device can analyze the amount of light entering the user's pupil, the number of blinks and the total duration of blinks based on factors such as pupil size, blinking, and whether the user wears a vision correction device to obtain the effective power W _o and the ineffective power W _on .

When the user's eyes are not looking directly at the light energy source, as shown in FIGS. 7 and 9 , the eye tracking device can analyze the amount of light entering the user's pupil, the total number of blinks and the length of blinks according to factors such as the mapping area of the pupil on the plane perpendicular to the light direction, the blinking situation, whether the vision correction device is worn, etc., to obtain the effective work W _s and the ineffective work W _sn , then the total effective work of the light energy source 20 actually entering the eye 10 is W= _Wo + _Ws . In order to achieve the ideal treatment effect, the ophthalmic medical device 1 dynamically adjusts the lighting parameters according to the effective work and the ineffective work. Specifically, when the calculated effective work W entering the eye is less than the set value matching the user, the total effective work entering the eye is guaranteed by extending the irradiation time of the light energy source 20 or increasing the output power of the light energy source 20, so as to better achieve the treatment effect. When the calculated 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 uniformly set to 3 minutes, it is more in line with the personalized needs of users and ensures a better treatment effect.

In this embodiment, after the user finishes using the ophthalmic medical device 1, the system will automatically generate a usage report for the user during that period and send it to the user. The user usage report includes the user's usage time, the effective work and ineffective work of the light energy source 20 entering the eye, the standard usage time and the irregular usage time of the ophthalmic medical device 1. The irregular usage time includes the time when the eyes 10 are closed when the light source enters the eye, the eyes are squinting, and the light source is not shining on the gaze point.

Accordingly, an embodiment of the present invention provides a medical device 1 for real-time analysis of effective eye power, including a light energy source 20, an image capture device 30, and a processing 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 obtain an image of the user's eye 10 and iris information. The image of the user's eye 10 and the iris information are transmitted to the processing control unit 40. The processing control unit 40 obtains user identification information based on the iris information, calculates and obtains the matching output power of the light energy source 20 corresponding to the user identification information based on 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.

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 human 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 of the captured human eye image, thereby completing the iris information collection. In addition, the medical device 1 of the present invention also includes a fill light unit 50, which provides the image capture device 30 with more suitable light for photographing the user's eyes 10. When a 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 eyes 10. In order to ensure that different output light powers are provided according to the different needs of the user's eyes 10 to obtain better treatment effects, the ophthalmic medical device 1 is provided with an image capture device 30 and a processing 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 control unit 40. The processing unit calculates and obtains the output power matching the user, and controls the output power of the light energy source 20 to adaptively adjust to the matching output power to ensure that the user obtains the eye-entry power suitable for him/her, which is more in line with the user's personalized needs and ensures that the user obtains a better treatment effect.

The processing and control unit 40 can analyze the information of the user's eyes 10 in real time during the user's use through the transmitted image information of the user's eyes 10 and obtain the effective eye power of the light energy source 20 entering the user's eyes 10, and make a judgment through the pictures taken by the eye tracking device and/or the image capture device 30; when the calculated effective eye 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 eyes 10, that is, when the output of the light energy source 20 meets the matching output power, the medical device 1 can automatically stop treatment to ensure the user's safety and personalized use needs.

The processing control unit 40 includes a processor 401 and a memory 402, wherein the memory 402 is configured to store an iris database corresponding to user identification information, and 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; 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. After the medical device 1 of the present invention identifies the user identification information currently being used, it further determines the matching output power suitable for the user.

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 (for example, close to the lens barrel), the image capture device 30 takes an image of the user's eye 10 to obtain relevant human 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 instrument's light energy source 20 to the matching output power corresponding to the user. In the use scenario of using the same ophthalmic medical device together, the different treatment power requirements of different users are met, and the user identity can be effectively and conveniently identified, avoiding confusion of user usage data.

Furthermore, 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, wherein the user configuration parameters at least include one or a combination of the output power of the light energy source 20, the user's pupil distance, and the treatment duration. For example, each user has different eye 10 treatment requirements, and the matching output power of the corresponding user 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 different user pupil distance data identified.

Furthermore, the ophthalmic medical device 1 in the embodiment of the present invention further includes a position adjustment unit 110, which includes a micromotor 111 and an adjustment frame 112 connected to the output mechanism of the micromotor 111. The light energy source 20 is arranged on the adjustment frame 112, and the light energy source 20 can move in the up-down, left-right or front-back directions under the drive of the micromotor 111. After the user identity is matched with the iris information in the database, the adjustment frame 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.

Furthermore, the ophthalmic medical device 1 further includes a display unit 120, which may be an LED display screen. After the processor 401 obtains the user identification information, the user can view the user configuration parameters or usage report of the user's last use through the LED display screen, which is not limited here. The light energy source 20 in this embodiment may be a controllable light source, the wavelength and/or light intensity of the controllable light source may be adjusted, and the controllable light source may adjust the light intensity according to the user pupil diameter information obtained by the image capture device 30.

Specifically, when the user uses the medical device 1 provided by the present invention, the image capture device 30 obtains information about the human eye 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. When the image capture device 30 photographs changes in the pupil of the human eye, the processing control unit 40 calculates the pupil diameter again according to the photographed image. If the calculated result is less than the pupil diameter calculated by the previous photograph, it is determined that the pupil is constricted. The processing control unit 40 controls the light energy source 20 to enhance the emission light intensity, thereby improving the accuracy of the light intensity entering the eye, ensuring that the accumulation of the entire light intensity entering the eye is a fixed value, so that the clinical data is more consistent. The image capture device 30 is an invisible light camera (such as an infrared camera) or a visible light camera, which is not limited here.

Preferably, the ophthalmic medical device 1 also includes a communication unit 130, which can transmit data wirelessly or wiredly with other devices through base station communication, Bluetooth communication, wifi communication or combined communication. In this way, users can export their own usage data and inspection reports and other information to other devices, which is convenient for users to view their own treatment parameters and historical usage 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 setting configuration and parameters again, and there is no need to worry about the loss of historical data. Through the transmission of the communication unit 130, data sharing and interconnection between two or more machines can be achieved.

10 , an embodiment of the present invention provides a method for adaptively adjusting the output power of a light energy source 20 of a medical device, wherein the medical device 1 includes a light energy source 20, an image capture device 30, and a processing control unit 40, wherein at least part of the light emitted by the light energy source 20 is directed to a user's eye 10, and the method includes the following steps:

The image capture device 30 obtains the image of the user's eye 10 and iris information;

The user's eye 10 image and iris information are transmitted to the processing control unit 40;

The processing control unit 40 obtains the user identification information based on the iris information, calculates the matching output power of the light energy source 20 corresponding to the user identification information based on the image information of the eye 10, and controls the output power of the light energy source 20 to adaptively adjust to the matching output power, so that the user can obtain a more optimized treatment effect that is more suitable for his or her needs.

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.

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.

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.

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.

As shown in FIG. 11 , an embodiment of the present invention provides a method for adaptively adjusting the position of a light energy source 20 of a medical device. The medical device 1 includes a light energy source 20, an image capture device 30, a processing 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 eye 10, and the method includes the following steps:

The image capture device 30 obtains the user's eye position information by real-time shooting, and transmits the user's eye 10 position information to the processing control unit 40; the processing control unit 40 calculates and obtains the relative position data of the user's eye 10 and the reference coordinate system of the medical device 1 according to the user's eye 10 position information, and the processing control unit 40 controls the position adjustment unit 110 to adjust the light energy source 20 to the corresponding position so that the light correctly enters the user's eye 10 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 shooting the human eye information, and the processing control unit 40 processes the iris information to obtain the user's identity recognition information.

As shown in FIG12 , the processing control unit 40 calculates and obtains the relative position data of the user's eye 10 and the reference coordinate system of the ophthalmic medical device 1 according to the position information of the user's eye 10 captured by the image capture device 30, and the processing control unit 40 controls the position adjustment unit 110 to adjust the light energy source 20 to the corresponding position so that the light correctly enters the user's eye 10 according to the relative position data. Specifically, as shown in the figure, with the center of the eyepiece 101 as the coordinate origin, the processing control unit 40 calculates the known coordinates (A, B) of the user's pupil on the image captured by the image capture device 30, the known focal length of the image capture device 30 is df, and the known position of the image capture device 30 from the user's eye 10 is d ₁ . The position coordinates of the pupil can be located by calculation as (x, y), where x=A*d ₁ /d _f , y=B*d ₁ /d _f . The processing control unit 40 adjusts the light source 20 to emit the light source facing the user's pupil according to the position coordinates of the user's pupil obtained by calculation. When the user's eyes 10 move left and right, the image capture device 30 captures the dynamic position of the eyes 10 in real time. The processing control unit 40 analyzes two new pupil coordinate positions by acquiring the real-time positions of the left and right pupils, and then adjusts the position of the light energy source 20 to achieve real-time tracking of the pupils during use by the user, so as to achieve the optimal treatment effect.

In one embodiment of the present invention, referring to FIG13 , when the user is a child, since the distance between the pupils of both eyes is relatively close, the ophthalmic medical device 1 calculates the coordinate position of the pupils and the position adjustment unit 110 automatically adjusts the positions of the two light energy sources 20 to the position facing the user's eyes accordingly. Referring to FIG14 , when 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 position facing the user's eyes accordingly based on the calculated coordinate position of the pupils, especially when multiple people share one ophthalmic medical device 1, it can be more easily and automatically adjusted to the treatment position required by the user to ensure a better treatment effect.

The processing control unit 40 includes a processor 401 and a memory 402. The controller and the memory 402 are 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 the user identification information corresponding to the user. Specifically, after the user has used the ophthalmic medical device 1, the memory 402 creates and stores the user data information in the memory 402. When a new user uses the ophthalmic medical device 1, by taking a photo of the iris for comparison, if the corresponding iris information is not matched in the memory 402, the memory 402 creates and stores the user identification information corresponding to the new user.

When a user uses the ophthalmic medical device 1 provided by the present invention, when the user brings his eyes close to the eyepiece 101, the image capture device 30 captures the user's 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 controller retrieves 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 at the same time due to different pupil positions.

In this embodiment, the ophthalmic medical device 1 further includes a fill light unit 50, which provides light for the image capture device 30 to photograph the user's eyes 10. Specifically, the fill light unit 50 is disposed in the ophthalmic medical device 1, and the light supplemented by the fill light unit 50 may be infrared light. When the user uses the ophthalmic medical device, the fill 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 image capture device 30 can clearly capture the user's iris image information.

Further, the memory 402 is also configured to store one or a combination of the user's historical usage data, user usage report, and user configuration parameters associated with the user identification information. Specifically, the user configuration parameters include the output power of the light energy source 20 when used by different users. The usage of each user is different, and the output power of the corresponding user is also different, including the pupil distance, treatment duration and other data of different users are matched according to the usage parameters of different users. 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 memory 402 matches the safe output power for different users. According to different personal situations, if a constant output power is used, the eyes 10 are damaged due to excessive output power for users with different situations, or the expected treatment effect is not achieved due to too small output power.

In one embodiment of the present invention, a medical device 1 with adaptive adjustment of the position of a light energy source 20 is provided, comprising a light energy source 20, an image capture device 30, a processing control unit 40 and a position adjustment unit 110, at least part of the light emitted by the light energy source 20 is directed to the user's eye 10, the image capture device 30 is configured to obtain the position information of the user's eye 10, the position information of the user's eye 10 is transmitted to the processing control unit 40, the processing control unit 40 calculates and obtains the relative position data of the user's eye 10 and the reference coordinate system of the medical device 1 according to the position information of the user's eye 10, and the processing control unit 40 controls the position adjustment unit 110 according to the relative position data to adjust the light energy source 20 to the corresponding position so that the light correctly enters the user's eye 10. In this embodiment, the position adjustment unit 110 comprises 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, and the light energy source 20 can move in the up-down, left-right or front-back direction in the reference coordinate system under the drive of the micro motor 111.

In a further technical solution, the image capture device 30 further obtains iris information of the user's eye 10, and the processing control unit 40 processes the iris information to obtain user identification information. The processing 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.

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 captures the user's eye information. When the user identity is matched with 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 of the user after the last use. Especially when multiple people share one machine in a hospital, the light energy source 20 can be automatically and quickly adjusted to a position suitable for the user's pupil distance, which is particularly convenient for younger users.

Furthermore, the light energy source 20 is an LED light source or a laser light source, and at least part of the light emitted is directed to the user's eye 10, for irradiating energy light waves into the user's eye 10, providing light energy to supplement the user's eye 10 with red light of a specific wavelength, improving fundus blood circulation to make the choroidal nutrition thicker, and achieving the purpose of controlling eye axis growth and preventing approximation. The image capture device 30 is an invisible light camera or a visible light camera, which is used to clearly and stably capture human eye information images, and then extract the outer diameters of the iris circle and the pupil circle through convenient feature extraction of the image, and segment the iris area to complete iris acquisition.

Furthermore, the ophthalmic medical device 1 also includes a position adjustment unit 110, which includes a micromotor 111 for detecting electrical signals and light source output power, an adjustment frame 112 connected to the output mechanism of the micromotor 111, and the light energy source 20 is arranged on the adjustment frame 112. When the user identity is matched with 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 up and down, left and right, or front and back directions under the drive of the micromotor 111.

Furthermore, the device also includes a display unit 120, which 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 used by the user last time, and the adjustment device automatically adjusts the light energy source 20 to the position used by the user last time. There is no limitation here.

Preferably, the ophthalmic medical device 1 also includes a communication unit 130. The communication unit 130 can transmit data with other devices wirelessly or by wire through base station communication, Bluetooth communication, wifi communication or combined communication. In this way, users can export their own usage data and inspection reports and other information to other devices, which is convenient for users to view their own treatment parameters and conditions in real time. Of course, the communication unit 130 can also transmit data wirelessly or by wire 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 setting configuration and parameters again, and there is no need to worry about the loss of historical data. Through the transmission of the communication unit 130, the data sharing and interconnection of the two machines can be realized.

Referring to FIG. 3 and FIG. 15 , another embodiment of the present invention provides an ophthalmic medical device 1 having a replaceable human contact component 150, which at least includes a light energy source 20, a first communication component 160, a processing 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 to have identity 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's identity information to 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 on the light feeding device that contacts the user's eye 10) is detachably connected to the ophthalmic medical device 1, it can be sold separately for exclusive use by the user, especially when multiple people in the hospital share an ophthalmic medical device, 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.

Specifically, the first communication component 160/the second communication component 140 can be a near field communication module, a barcode communication module or an electrical connection communication module. The near field communication module includes at least one of a WIFI communication module, a wireless radio frequency identification RFID communication module, an NFC near field communication module, a Bluetooth communication module, a wireless personal area network Zigbee communication module, a set frequency band wireless communication module (such as 433MHz), a magnetic field communication module, and an acoustic magnetic communication module. The barcode communication module can include a one-dimensional code (such as code 128, a barcode EAN for goods, a unified product code UPC), a two-dimensional code (such as Data Matrix, QR code). The user identity information contained in the one-dimensional code or the two-dimensional code can be read by the image capture device 30 in the ophthalmic medical device 1. The electrical connection communication module can include at least two electrical contacts that can be electrically connected to the ophthalmic medical device 1, and the information related to the user identity is transmitted through the opening and closing signals of the electrical contacts.

At least part of the light emitted by the light energy source 20 is directed 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, and provide light energy supplement of a specific wavelength for the user's retina, such as for the treatment of juvenile myopia or amblyopia. Referring to Figure 16, in a specific embodiment of the present invention, an NFC near-field communication module is set in the human body contact component 150, and each user can be equipped with its own dedicated human body contact component 150 and bind its unique user information, such as a unique serial code 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 code used to identify the user's identity to the first communication component 160 of the ophthalmic medical device 1, so that the ophthalmic medical device 1 obtains the identity information and transmits it to the processing control unit 40. The processing control unit 40 of the ophthalmic medical device 1 can obtain the user's identity information based on the identity information, and provide a further optimized treatment plan based on the user's usage or the condition of the eye 10 to meet the different treatment needs of the user.
