When an ophthalmologist checks the eye health condition of a patient, different parts of two eyes of the patient are usually required to be checked, and the duration of the check is longer because of more parts to be checked and more acquired data. If the patient himself has dry eye or other chronic diseases which lead to eye fatigue, obvious fatigue symptoms occur during the examination. After evaluating the condition, the doctor considers that it is necessary to use specific eye drops which have little influence on the examination result to relieve fatigue. When eyes of a patient are opened for a long time, sour and astringent feeling can be generated, and if the eye drops for relieving fatigue are directly sprayed to the eyeballs of the patient, the eyes of the patient can generate stronger uncomfortable feeling, and even the eyeballs are injured.
In view of this, we propose an ophthalmic examination assistance device based on a smart diagnostic system to ameliorate the deficiencies of the prior art.

Further, when eyes of a patient feel uncomfortable, the nozzle 42 is opened to spray water into the L-shaped spray pipe 43, and as the outside of the nozzle 42 is movably connected with the inside of the L-shaped spray pipe 43, when the nozzle 42 sprays eyedrops, the turning part of the L-shaped spray pipe 43 is forced to move forwards, the baffle plate at the periphery of the L-shaped spray pipe 43 drives the atomizing plate 41 to move forwards again, the atomizing plate 41 drives the rack 23 to be meshed with the driven gear 31 which rotates forwards, so that the fan 32 at the top of the driven gear 31 rotates forwards, one end of the L-shaped spray pipe 43 far from the nozzle 42 is provided with a filter plate, the sprayed eyedrops pass through the filter plate and then strike the inner wall of the guide pipe 33, atomized eyedrops are formed in the inner cavity of the guide pipe 33, at this time, the lighter-weight atomized eyedrops are pumped around the eyes of the patient by the fan 32 which rotates forwards, and excessive eyedrops with larger weight are discharged out of the inspection cavity 11 through a hole channel formed at the bottom of the guide pipe 33;
Still further, the thrust of the water jet ejected by the nozzle 42 against the atomizing plate 41 is greater than the sum of the friction forces between both the shuttle assembly 20 and the camera 13 and the inspection chamber 11.

Since different parts of the eyes of a patient need to be inspected, and a plurality of images are taken to reduce the error of the inspection;
The reciprocating assembly 20 comprises a reciprocating ring 21, a connecting rod is arranged at the top of the reciprocating ring 21 and is in sliding connection with the inner top wall of the inspection cavity 11, a driving gear 22 is meshed in the reciprocating ring 21, the driving gear 22 is driven by a motor, racks 23 are fixedly connected to two sides of the reciprocating ring 21 adjacent to the camera 13, and the two racks 23 are symmetrical about the center.
The improvement is that after the power is turned on, the motor drives the driving gear 22 coaxially connected with the output shaft of the motor to rotate, and the driving gear 22 drives the reciprocating ring 21 to drive the camera 13 to do left and right reciprocating motion, so that different parts of the eyes of a patient are shot.
Under the driving of the shuttle ring 21, the camera 13 takes a large number of pictures of different parts of the eyes of the patient within a period of time, the information of the pictures is doped with unusable interference information such as noise, blurred images and the like, the interference information needs to be cleared before the monitoring and diagnosis of the patient, and then the health condition of the eyes of the patient is diagnosed based on a preset built-in algorithm and the cleaned patient characteristic information.
In summary, the working principle of the present solution is as follows, firstly, the patient puts his head in the positioning mask 12, and after the positions of the eyes are positioned, the reciprocating ring 21 is started to drive the camera 13 to reciprocate left and right, so as to complete the examination of the different positions of the eyes of the patient. With the increase of the inspection time, if the eyes are sour and uncomfortable in the middle of the patient, in order to prevent from affecting the inspection result, the atomization assembly 40 is started to spray the eye drops into the L-shaped spray tube 43, when the nozzle 42 sprays the eye drops, the turning part of the L-shaped spray tube 43 is forced to move forward due to the movable connection between the outer part of the nozzle 42 and the inner part of the L-shaped spray tube 43, the baffle plate at the periphery of the L-shaped spray tube 43 drives the atomization plate 41 to move forward, the atomization plate 41 drives the rack 23 to be meshed with the driven gear 31 which rotates forward, so that the fan 32 at the top of the driven gear 31 rotates forward, one end of the L-shaped spray tube 43 far from the nozzle 42 is provided with a filter plate, the sprayed eye drops pass through the filter plate and then strike the inner wall of the guide tube 33, atomized eye drops are formed in the inner cavity of the guide tube 33, at this moment, the atomized eye drops with lighter weight are pumped around the eyes of the patient by the fan 32 which is driven by the forward rotation, so that the sour and astringent of the eyes of the patient are relieved, and the excessive eye drops with greater weight are discharged outside the inspection cavity 11 through the hole channel formed at the bottom of the guide tube 33. At this time, the spring 52 is driven by the atomizing plate 41 to be in a stretched state. As the time for which the nozzle 42 sprays the eye drops increases, the excessive eye drops also cause discomfort to the eyes of the patient, thereby affecting the examination result. At this time, after the nozzle 42 is closed to stop spraying the eyedrops, the atomizing plate 41 loses the driving force of the nozzle 42 to spray the water column, and then the rack 23 is driven to mesh with the driven gear 31 at the bottom of the reversing fan 32 under the action of the restoring force of the atomizing plate, the reciprocating ring 21 drives the driven gear 31 at the bottom of the reversing fan 32 to rotate through the rack 23, and the reversing fan 32 then guides more atomized eyedrops originally positioned around the eyes of a patient away from the periphery of the eyes of the patient, so that discomfort of the eyes of the patient caused by excessive eyedrop spraying amount is prevented. During this time, the diagnostic module 60 receives the image information captured by the camera 13 and analyzes it to diagnose the patient's eye health in conjunction with the built-in algorithm.
Example 2
This embodiment provides according to embodiment 1 with the aim of providing a diagnostic module 60 for receiving the data acquired by the camera 13 and analysing the health of the patient's eyes accordingly.
The diagnostic module 60 includes an acquisition unit 61, an extraction unit 62, a diagnostic unit 63, and an output unit 64;
The acquisition unit 61 is configured to receive data generated by the camera 13 and clean the data, the extraction unit 62 performs feature extraction on the cleaned data to identify key features related to the eye health condition, the diagnosis unit 63 analyzes the extracted features according to a deep learning algorithm, and the output unit 64 is configured to output an analysis result of the diagnosis unit 63.
The improvement is that the acquisition unit 61 receives data generated by the camera 13, including fundus photos, scleral color, retrobulbar arterial hemodynamic parameters, etc. These data may then undergo a preprocessing stage to remove noise, enhance key features, normalize the data format, etc., to improve the accuracy of subsequent analysis. The preprocessed data is subjected to the extraction unit 62 to obtain feature information to identify key features related to the eye health. These features include color, texture, shape, etc. Feature extraction involves image processing techniques such as image segmentation, edge detection, morphological operations, etc. The diagnosis result including information of the eye disease, the severity of the disease, etc. that the patient may suffer from is outputted through the analysis of the diagnosis unit 63. The diagnosis results include treatment advice, follow-up plans, etc., to assist the doctor in making subsequent diagnoses.
Since it is necessary to diagnose the eye health condition of the patient based on the extracted eye feature information of the patient, the diagnosis unit 63 analyzes the extracted feature according to the deep learning algorithm, and the method of judging the eye health condition of the patient accordingly includes the steps of:
s1.1, initializing model parameters including weights and biases;
S1.2, forward propagation, namely calculating the output of a model according to the data acquired by the acquisition unit 61 and preset weight and bias parameters;
s1.3, calculating loss, namely comparing the model output value with the difference of the re-acquired data of the camera 13 after the eye drops are sprayed to obtain a loss value;
s1.4, back propagation, namely calculating gradient according to the loss value, and updating model weight and bias parameters;
s1.5, iterating the steps until a stopping condition is met, wherein the stopping condition comprises the maximum iteration times and the convergence of the loss value.
The weights are parameters between connected neurons in the neural network for adjusting the importance of each input signal. It represents the extent to which each input contributes to the output of the neuron. The magnitude of the weights determines the extent to which the input signal should be scaled up or down before passing on to the next layer. The weights and biases are initialized to small random values.
The weight and bias determination steps are as follows:
S2.1, initializing, namely adopting uniform distribution, normal distribution and the like in an initializing method, wherein the specific selection depends on the structure of a visual neural network and task requirements to be diagnosed;
S2.2, training, namely firstly, forward propagation is carried out on input data by a model, and errors between a predicted result and a real result are calculated. The back propagation algorithm then uses this error to calculate the gradient of the loss function with respect to each weight and bias. The gradient indicates the rate of change of the loss function at that point, i.e. how the parameters need to be changed to reduce the total error.
And S2.3, updating, namely updating the weight and the offset value according to the gradient by using an optimization algorithm (such as gradient descent). This process is repeated for a number of iterations until the performance of the model reaches a satisfactory level.
When the weights and biases are initialized with a normal distribution, the normal distribution (also called gaussian distribution) is a continuous probability distribution whose shape is determined by the mean (μ) and standard deviation (σ). In the initialization of the weights and biases, the mean is typically set to 0, while the standard deviation is adjusted according to the needs of the specific needs for diagnosing what kind of disease.
When the eyes of the patient feel dry and uncomfortable and the patient is difficult to support for further examination, the nozzle 42 is activated to spray and atomize the eye drops into the examination cavity 11, and then the drainage assembly 30 guides the atomized eye drops to the vicinity of the eyes of the patient. In order to prevent the water mist from affecting the clarity of the image of the eyes of the patient collected by the camera 13, the camera 13 is suspended in the process of spraying the eyedrops to relieve the eye fatigue of the patient.
After the relief of the eye fatigue of the patient is completed, the acquisition unit 61 calculates the concentration of the eye drops around the camera 13 according to the light scattering algorithm, and decides whether the camera 13 resumes operation according to the calculation result, using the formula:
;
the meaning of each coincidence in the formula is as follows:
-water mist concentration;
-calibration coefficients related to chamber structure, wavelength of light and particle size distribution of water mist;
-the intensity of the scattered light;
-intensity of incident light;
When (when) When the calculated value of (2) is lower than the preset water mist concentration value, the camera 13 begins to work again, reciprocates along with the reciprocating ring 21, continues to collect image data for different parts of the eyes of the patient again, then compares the data collected after the camera 13 is operated again with the model output value, the difference between the two is called a loss value, and the weight and the bias parameter of the model are updated according to the size of the loss value.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, and that the above-described embodiments and descriptions are only preferred embodiments of the present invention, and are not intended to limit the invention, and that various changes and modifications may be made therein without departing from the spirit and scope of the invention as claimed.
