Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In one embodiment of the present invention, as shown in fig. 1, a medical device for applying light energy to eyes includes a light energy source 20, an image capturing device 30 and a processing control unit 40, at least part of light emitted from the light energy source 20 is directed to eyes 10 of a user, the image capturing device 30 is configured to obtain eye image information, and the processing control unit 40 processes the eye image information to obtain information related to usage of the user. The medical device 1 of the present invention may be used for the treatment of, but not limited to, ocular diseases such as myopia, amblyopia, macular degeneration (AMD), diabetic retinopathy, glaucoma, etc.

Specifically, taking a treatment approach of a medical device for applying light energy to eyes by a user according to the present invention as an example, the image capturing device 30 obtains eye image information and transmits the eye image information to the processing control unit 40, and the processing control unit 40 calculates and obtains relevant information of the use condition of eyes of the user after receiving the information transmitted by the image capturing device 30. Further, the user usage related information at least includes one or more of information of whether the user opens eyes and uses correctly, user pupil diameter information, user pupil gaze angle information, user pupil position information, information for identifying the user, user effective use time information, total light power information received by the eyes 10 of the user, and user interpupillary distance information, that is, irregular user usage conditions such as eye closure and the like when the user uses are corrected through algorithm processing, so that the treatment effect of the user in the use process is ensured.

In an embodiment of the invention, the medical device for applying light energy to an eye further comprises a light distribution member 60, a light detector 80 for detecting light intensity, the light distribution member 60 directs at least a portion of the light emitted by the light energy source 20 to the light detector 80 for detecting the emitted light intensity emitted by said light energy source, the light distribution member 60 directs another portion of the light emitted by the light energy source 20 to the eye 10 of the user, and the reflected light directed to the eye 10 of the user enters the image capturing device 30 via the light distribution member 60 for obtaining eye image information.

Further, in use of a medical device for applying light energy to the 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 received by the light detector 80 in part by the light distributor, which receives the other part of the light waves emitted by the light energy source 20 by the user's eye 10 and reflects the light reflected by the eye 10 through the light distribution member 60 onto the image capturing device 30.

Still further, the light energy source 20 is a controllable light source, the wavelength and/or intensity of which is adjustable. The processing control unit 40 includes a processor 401 and a memory 402, the memory 402 is configured to store a table of correspondence between eye image information and emitted light intensity of the light energy source 20, the emitted light intensity of the light energy source 20 and the eye image information acquired by the image capturing device 30 are transmitted to the processor 401, and the processor sends a signal for adjusting the light intensity of the controllable light source to the controllable light source according to the received emitted light intensity, the eye image information and the table of correspondence.

Specifically, the eye image information includes at least user pupil diameter information, the memory 402 is configured to store a correspondence table of user pupil diameter information and emitted light intensity, and the processing control unit 40 adjusts the light intensity of the controllable light source according to the emitted light intensity, the user pupil diameter information, and the correspondence table received in real time. For example, when the pupil diameter captured by the image capturing device 30 is reduced, the processor 401 may signal the controllable light source to fine tune the increase in emitted light intensity.

In particular, the light distributor may be a beam splitter, for dividing the emission light source into two beams of light reflected downwards and directed leftwards, and 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 from the light energy source 20 into the user's eye 10 and direct another 50% of the light from the light energy source 20 into the light detector 80, thereby allowing the light detector 80 to accurately detect the light power from the light energy source 20.

In a preferred embodiment, as shown in fig. 2, at least one filter element 70 is provided between the light energy source 20 and the light distribution member 60 or between the light detector 80 and the light distribution member 60 or between the image capturing device 30 and the light distribution member 60. Specifically, the filter element 70 may be a bandpass filter, a low-pass filter or a high-pass filter, and in this embodiment, a bandpass filter is disposed between the light energy source 20 and the light distribution member 60, through which the light waves purify the wavelengths when the light energy source 20 emits the light waves. Further, for example, the light energy source 20 emits light having a wavelength of 650-680nm, and the half-width wavelength can be reduced to a narrower half-width wavelength range when the light energy source 20 emits light having a wavelength that passes through the bandpass filter.

When the light wave emitted by the light energy source 20 passes through the band-pass filter between the light energy source 20 and the light distribution component 60, in order to prevent the rest of stray light from reflecting to the image capturing device 30 and thus affecting the shooting of the image capturing device 30, the light wave emitted by the light energy source 20 is filtered out by arranging a low-pass or high-pass filter between the image capturing device 30 and the light distribution component 60, and only a small part of the light wave is used for specific prompt in the image, so that the image capturing device 30 cannot exceed a reasonable dynamic range due to the too strong light intensity, and the safety of the use of a user is ensured.

In the present embodiment, the same bandpass filter as that between the light energy source 20 and the light distribution member 60 is provided between the light distribution member 60 and the light detector 80, and also, when the light energy source 20 emits laser light to reach the light detector 80 through the light distribution member 60, it is used to block stray light in the light wave, thereby ensuring the accuracy of measurement by the light detector 80. The closed-loop monitoring of the light intensity output of the light energy source 20 is truly realized through the accurate detection of the light intensity of the incident eye and the eyeball state, and the use safety and reliability of the medical device are improved.

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 member 60. Specifically, when the light energy source 20 emits light waves, the light waves irradiate the light-splitting assembly through the collimating element 90, and the light waves emitted by the light energy source 20 change the irradiated divergent light into parallel light through the collimating element 90, so that the light source is shortened to cover parallel light spots with the diameter of about 10mm of the human eyes, and the stability of the light source is ensured.

In the present embodiment, at least one focusing element 100 is provided between the image capturing device 30 and the light distributing section 60. The focusing element 100 is similar to adjusting a suitable detection focus, and when the image capturing device 30 captures human eye information of a user, in order to ensure that a captured detected image of a human eye position is the most clear, the focusing element 100 is disposed in front of the image capturing device 30, so that the image capturing device 30 can capture the most clear human eye information through the suitable detection focus. By improving the light path, the invention greatly reduces the volume of the medical device for applying light energy to eyes, can make the whole structure lighter and is convenient for users, especially low-age users.

In a preferred embodiment, the present invention further comprises a thermostat for providing a set operating environment temperature for the light detector 80 and/or the light energy source 20, in particular, to ensure a wide output operating range and detection accuracy of the medical device 1 of the present invention, the thermostat may be controlled to operate by the processing control unit 40, for example, the ideal operating environment temperature is 25 ℃, and when the external temperature is higher or lower than 25 ℃, the processing control unit 40 controls the thermostat to start operating, keeping the operating environment temperature constant at 25 ℃, and the thermostat may be a TEC refrigerator, a compressor, or the like.

In the calibration phase prior to use of the ophthalmic medical device 1 of the present invention, calibration curves can be made for the light energy source 20, the light detector 80 by using a device test that passes the metering certification at the eyes of the user, after which the actual light intensity can be monitored according to this curve during actual use by the user. The light energy source 20 in this embodiment is a controllable light source, the wavelength and/or light intensity of which is adjustable, and the controllable light source adjusts the output light intensity of the controllable light source according to the pupil diameter information of the user acquired by the image capturing device 30.

Specifically, when the user uses the medical device 1 provided by the present invention, the image capturing device 30 obtains human eye information by capturing a human eye and transmits the human eye information to the processing control unit 40, for example, 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 capturing device 30 captures the change of the pupil of the human eye, the processing control unit 40 calculates the diameter of the pupil again according to the captured image, if the calculation result is smaller than the pupil diameter calculated in the previous capturing, it is determined that the pupil is contracted, and 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 of the incident eye, ensuring that the accumulation of the whole light intensity of the incident eye is a fixed value, and enabling the clinical data to have more consistency. The image capturing mechanism 30 is not limited herein as it may be an invisible light camera (e.g., an infrared camera) or a visible light camera.

Especially when one device is used in a scene of a hospital, clinic or family for multiple persons, a user only needs to place the eyes 10 at the correct use position before treatment starts, and the iris data can be compared by starting the medical device 1 for automatic identification of the user, so that the users can be effectively and conveniently distinguished, and confusion of the user data is avoided.
