FIG. 2 is a schematic structural diagram of a transmission bracket of the smart eye drops atomizer according to the embodiment.

Detailed ways

As shown in FIG. 1 , this embodiment provides an intelligent eyedrops atomizer, including an equipment rack 10 and an atomization mechanism;

The above-mentioned equipment rack body 10 includes a main rack body and a supporting rack body that are connected to each other. Generally speaking, the equipment rack body is in the shape of glasses. Two functional windows, the support frame of which is an openable temple or an elastic strap;

Due to the window, the visual function will not be affected during the activation of the device, so that patients, especially children, can be treated in the case of external incentives (such as playing movies, children's cartoons, etc. at the same time). Keep your eyes open to achieve the spray effect.

On the main frame body, there is an embedded guide rail 11 generally located at the position of the upper frame body;

A transmission frame body 20 is installed in the guide rail of the main frame body;

The transmission frame body 20 can be a frame-type structure or a semi-enclosed structure, and has a space for accommodating the atomizing device. When the atomizing device is installed on it, the atomizing device can be firmly locked, and the The equipment space is facing the human eye position. After the installation of the atomizing device is completed, make the atomizing device, especially its spray port, facing the human eye.

As shown in FIG. 2 , since most of the atomizing devices are in the shape of cylinders, in this embodiment, the frame body 20 has a semi-cylindrical space 201 inside, and the semi-cylindrical space 201 is generally higher than The height of the atomizing device, when the atomizing device is installed in it, its back and bottom should be close to the semi-cylindrical space. Considering that the atomizing device can be a cuboid or other shapes, in order to achieve the effect of supporting use, the internal space of this part can be synchronously transformed.

In this embodiment, the two sides of the middle and lower part of the transmission frame body, avoiding the spray port of the spray equipment, have a belt-shaped fixing strip and a buckle structure 202. After the atomization equipment is installed in it, the belt-shaped fixing strips The strip realizes the fixation of the atomizing device.

In addition, the fastening structure can also be that the middle and lower part of the transmission frame body is an arc-shaped door-like structure, which can be opened and closed like a side buckle (such as a thermos bottle cap push switch, an elastic switch of a switch knife, etc.) .

Alternatively, the inner two sides of the semi-cylindrical space are provided with elastic buckle structures, which are fastened when the atomizing device is pressed into the space, and the buckle is released by pressing the switch outside the space.

As shown in FIG. 1 , the frame end of the transmission frame 20 has a slider 21 , and the slider 21 matches the structure of the guide rail 11 . In this embodiment, because the lower end of the equipment frame 10 is an arc structure Therefore, it is not suitable for installing matching guide rails and other structures. Therefore, the lower end of the transmission frame body 20 has an abutting plate 22, and the abutting plate 22 abuts on the arc structure position of the lower end of the equipment frame body 10, and the atomization device is installed. Then, due to the action of gravity, the abutting plate 22 moves against the arc structure.

Considering the effects of stability during the moving process, the lower end of the equipment rack 10 may have an electromagnet, and the corresponding position of the contact plate has a magnetic structure. When the equipment is moving, the electromagnet is not energized. When the equipment reaches the designated After the position is stationary, the two structures are fixed by magnetic force when energized.

As shown in Figure 1, the above-mentioned atomization mechanism includes atomization equipment and a control unit 30;

The atomizing device 40, after being installed on the transmission frame body 20, moves within the functional window range under the action of the transmission frame body 20;

The transmission frame also includes a communication power-on line that is in electrical communication with the control unit, and drives related equipment, under the action of such equipment, the movement of the entire transmission frame is realized.

The atomization device can use the existing electronically controlled atomization device (with a communication line connected with the control unit, so as to receive instructions from the control unit to realize the start and stop of the device, considering the convenience of disassembly and assembly of the device) The communication line can be plug-in type), the physical and chemical equipment uses vibrating mesh technology to achieve the effect of generating uniform atomized particles and high-efficiency atomization, and the atomization equipment is capable of atomizing 1-2 eye drops. Medicated eye nebulizer.

In addition, the atomization device can also be an intelligent control device with a communication module, the communication module can realize the start and stop control of the device by receiving the signal from the control unit, and can also send atomization to the control unit through the communication module. volume data.

Like conventional nebulizers, the nebulizer has a removable liquid storage box into which liquid can be poured or withdrawn.

There is a metering module on the atomizing device;

After the atomization equipment is started to spray, the metering module will count the total amount of spray of the atomization equipment from time to time. In this case, the metering module only needs to count the effective spray time;

In addition, when the total amount of spray counted by the metering module reaches the set threshold (the set amount can be adjusted by the front end of the control unit), it will feedback to the control unit to complete the set target, and the control unit's atomization equipment will no longer spray.

In addition, the atomizer assembly also includes a camera device 50, the camera device is an intelligent probe with a communication module, which can send picture information to the control unit from time to time, and is activated and deactivated under the control of the control unit;

The camera is installed on the side of the equipment bracket, and its camera is facing the direction of the human eye. It is preferably a camera based on the principle of infrared imaging, because the visual cells on the retina cannot induce infrared light. Some of them are clearly distinguished, among which the darkest area is the pupil area, the bright spot in the pupil area is the corneal reflection spot, and the outer pupil area is the iris area, the sclera area and the human skin.

The camera device, when activated, captures images at a set frequency (eg, 10 times/s), and sends the images to the camera module.

The above-mentioned control unit is generally an integrated chip, which is electrically connected to each component, and has the functions of supplying power (external or charging mode) and receiving and sending signals with each component. The screen can control and select information such as: stop/start equipment, setting of liquid volume, patient selection and so on.

The control unit includes a start-stop module, a storage module, a camera module, an image recognition module and an instruction module;

The start-stop module controls the start, stop and termination of the entire process;

When the start-stop module receives the start-up command from the front end of the device and controls the start of the entire process, the start-up sound is activated;

When the metering module instructs the atomizing device to stop spraying, it sends a program termination feedback to the start-stop module. The start-stop module instructs all devices to return to the initial state and activates the end beep.

The storage module stores the atomization data of each user each time, and sends it to the client (held by the patient) or the working end (the medical platform, which can be consulted by doctors).

The camera module controls the start or stop of the camera device, instructs the camera device to take pictures at a set frequency, and receives all image information sent from the camera device;

The image recognition module identifies and analyzes the image information to determine whether the current atomizing device is within the center position of the eye. The specific infrared image processing method can be used: first, study the change of the RGB component of the eye with temperature, Choose to process data on the component images that vary most with temperature. Secondly, in order to improve the imaging quality, different contrast enhancement algorithms and filtering algorithms are studied. According to the real-time requirements, the image is segmented, and the standard deviation is used to reflect the characteristics of data volatility, and the standard deviation is calculated for the sub-images multiple times. Finally, according to the special situation of the eyes, the star ray method is used to obtain the pupil boundary point. In the set region of interest, the false feature points generated by eyelid, eyelashes and light spot interference are eliminated, and then the center of the pupil is located by random ellipse fitting using the feature points.

In addition, the image recognition module also needs to recognize whether the person's eyes are closed or opened, that is, whether the pupil position can be recognized.

The command module receives commands from each module and sends commands to the target component.

For example: under the action of the control unit, when the atomizing device fails to be within the pupil range, the transmission bracket is instructed to move to the specified position;

Under the action of the control unit, in a specified situation, such as: when the eyes are opened, the atomization function is activated, and when the eyes are closed, the atomization function is stopped.

The specific working process can be as follows:

Install the nebulizer on the transmission bracket, start the equipment, select the patient or create a new patient information, manually check the spray volume and the name of the sprayed medicine, and start the procedure after confirmation.

First, the metering module will estimate the remaining amount of content in the atomizing device according to the weight;

When the start-stop module receives the start-up command from the front end of the device, it requests the metering module for the remaining amount of the content, and judges whether the remaining amount of the content is not less than the current usage *X times in the start-up command (X is based on manual settings or machine customization);

When the result is "No", the information is displayed on the front of the device, and the warning amount is too small to start normally;

When the result is "Yes", control the whole process to start;

When the process starts, the shooting device is activated and starts to take pictures at the set frequency. The image recognition module analyzes the pictures as follows:

S1. Obtain picture N (generally starting from the picture whose count is 1);

S2. Determine whether the content displayed in the current picture can identify eye features;

When the result is "Yes", continue to S3;

When the result is "No", obtain picture N+1, and repeat S2;

S3. Determine whether the current atomizing device is in the best spray position (that is, the position of the pupil in the picture, whether it is the position within the center range, such as: the center coordinate of the picture is within 0.2cm range);

When the result is "Yes", continue to S4;

When the result is "No", calculate the displacement distance (according to left or right, set the reverse moving distance, for example: when the deviation from the center coordinate is 0.4, the displacement is 1cm, etc., this is based on the original sprayer and the normal state The distance of the lower eye is the result of proportional conversion), and after instructing the transmission mechanism to move, repeat S1;

S4. Get the latest picture at the current time;

S5. Determine whether the content displayed in the current picture can identify the eye features (that is, whether the pupil can be identified, when it can be identified, it is identified as an open eye state, and when it cannot be identified, it is identified as a closed eye state);

When the result is "Yes", immediately start the atomization function of the atomization device, and obtain the latest picture of the updated current time, and repeat S5;

When the result is "No", obtain the latest picture of the updated current time, and repeat S5;

Continue the above process until the total liquid output counted by the metering module reaches the set value. When it is reached, the device is stopped and restored to its original state, and information such as the time and metering of this atomization is recorded.
