Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

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

Specifically, taking the near-field medical device for applying light energy to eyes of the user as an example, the image capturing device 30 acquires eye image information and transmits the eye image information to the processing control unit 40, and the processing control unit 40 receives the information transmitted by the image capturing device 30 and calculates and acquires information related to the usage of eyes of the user. Further, the information related to the user usage at least includes one or more combinations of information on whether the user opens the eyes for correct use, user pupil diameter information, user pupil gazing angle information, user pupil position information, information for identifying the user, user effective usage time information, information on the sum of optical powers received by the user's eyes 10, and user interpupillary distance information, that is, irregular user usage such as eyes closing when the user uses the device is corrected through algorithm processing, and the treatment effect of the user during the usage process is ensured.

In one embodiment of the present invention, the medical device for applying light energy to the eye further comprises a light distribution component 60, a light detector 80 for detecting light intensity, the light distribution component 60 directs at least a portion of the light emitted from the light energy source 20 to the light detector 80 to detect the emitted light intensity emitted from the light energy source, the light distribution component 60 directs another portion of the light emitted from 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 capture device 30 via the light distribution component 60 to obtain eye image information.

Further, the light energy source 20 is an led light source or a laser light source when the user is using a medical device that applies light energy to the eye. The LED light source or laser light source emits light waves that are received by the light detector 80 through the light distributor, which receives another portion 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 distributing member 60 onto the image capture device 30.

Further, the optical energy source 20 is a controllable light source, the wavelength and/or intensity of which is adjustable. The processing control unit 40 comprises 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 optical energy source 20, the emission light intensity of the optical 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 emission light intensity, the eye image information and the correspondence table.

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

Specifically, the light distributor may be a beam splitter for splitting the emission light source into two beams of light that are reflected downward and directed leftward, and the splitting ratio of the beam splitter may be set by a manufacturer. For example, the beam splitter may direct 50% of the light emitted by the light energy source 20 into the user's eye 10 and another 50% of the light emitted by the light energy source 20 into the light detector 80, thereby allowing the light detector 80 to accurately detect the optical power emitted by the light energy source 20.

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

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, in order to prevent the remaining stray light from being reflected to the image capturing device 30, thereby affecting the shooting of the image capturing device 30, the low pass or high pass filter is arranged between the image capturing device 30 and the light distribution component 60, so that the light waves emitted by the light energy source 20 are filtered, and only a small part of the light waves are reserved for specific prompts in the image, thereby preventing the image capturing device 30 from exceeding a reasonable dynamic range due to too strong light intensity, and ensuring the use safety of users.

In the present embodiment, the same bandpass filter as that between the optical energy source 20 and the optical distribution component 60 is disposed between the optical distribution component 60 and the optical detector 80, and similarly, when the laser emitted by the optical energy source 20 passes through the optical distribution component 60 and reaches the optical detector 80, the bandpass filter is used to block stray light in the optical wave, thereby ensuring the accuracy of measurement by the optical detector 80. The closed-loop monitoring of the light output of the light energy source 20 is really realized by accurately detecting the eye-entering light intensity and the eyeball state, and the use safety and the reliability of the medical device are improved.

At least one collimating element 90 for focusing light from the optical energy source is disposed between the optical energy source 20 and the light distributing component 60. Specifically, when the light energy source 20 emits light waves, the light waves penetrate through the collimating element 90 and irradiate on the light splitting fitting, and the light waves emitted by the light energy source 20 change irradiated divergent light 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 10mm covering 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 member 60. The focusing element 100 is used for adjusting a proper detection focus, and when the image capture device 30 captures information of human eyes of a user, in order to ensure that a captured detection image of the positions of the human eyes is 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 information of the human eyes through the proper detection focus. By the improvement of the optical path of the invention, the volume of the medical device for applying light energy to the eyes is greatly reduced, the whole structure is lighter and more convenient for users, especially for the users of the younger age.

In a preferred embodiment, the present invention further comprises a thermostat device for providing a set working environment temperature for the light detector 80 and/or the light energy source 20, and in particular, to ensure a wide output working range and detection accuracy of the medical device 1 of the present invention, the thermostat device can be controlled by the processing and control unit 40 to work, for example, the working environment temperature is ideally 25 ℃, when the external temperature is higher or lower than 25 ℃, the processing and control unit 40 controls the thermostat device to start working, so as to keep the working environment temperature at 25 ℃ constantly, and the thermostat device can be a TEC refrigeration plate, a compressor, or the like.

During the calibration phase before the ophthalmic medical device 1 of the present invention is used, the calibration curve can be made for the light energy source 20 and the light detector 80 by testing the user's eyes with a device that passes the measurement certification, and then the actual light intensity can be monitored during the actual use of the user. The light energy source 20 in this embodiment is a controllable light source, the wavelength and/or the 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 captures the human eye information by capturing the human eye and transmits the human eye information 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 capturing device 30 captures the change of the human eye pupil, 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 by the previous capture, 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, so as to improve the accuracy of the eye entrance light intensity, ensure that the accumulation of the whole eye entrance light intensity is a fixed value, and make the clinical data more consistent. The image capturing device 30 is a non-visible light camera (e.g., an infrared camera) or a visible light camera, and is not limited herein.
