Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] A meibomian gland massage teaching tool, such as Figure 1-4As shown, the device includes a face teaching aid 1 and an eye manipulation strap 2. Both the face teaching aid 1 and the eye manipulation strap 2 are made of silicone, which can simulate the feel and shape of a human face. The eye manipulation strap 2 is connected to the eye position of the face teaching aid 1 and can be detached and replaced separately. This design addresses the easy wear and tear of teaching aids during teaching operations; the detachable design allows for individual replacement and maintenance if either part is damaged, reducing maintenance costs. The face teaching aid 1 has an eye socket groove 14 at the eye position, which is used to accommodate a simulated eye socket body 5. The eye manipulation strap 2 includes the eye socket body 5, which is embedded in the eye socket groove 14. An eyeball 8 is connected inside the eye socket body 5. The eyeball 8 makes the simulation teaching aid more realistic and provides a realistic operating feel. The upper eyelid 16 is located at the top of the main body 5 of the eye socket, and the lower eyelid 6 is located at the bottom of the main body 5 of the eye socket. Both the upper eyelid 16 and the lower eyelid 6 are made of silicone and are designed with high realism. Massage operations can be performed on them, and key operations such as pulling up, pulling down, and inward and outward turning of the eyelids can also be realized. They are the core of realizing the training function. Furthermore, the upper eyelid 16 and the lower eyelid 6 can be injected with contents to simulate the eyelids of patients with meibomian gland dysfunction. Pressure sensors 12 are installed inside the upper eyelid 16 and the lower eyelid 6. The pressure sensors 12 are connected to a buzzer alarm 13. The buzzer alarm 13 is electrically connected to the pressure sensors 12. The pressure sensors 12 can monitor the massage intensity in real time and then transmit it to the buzzer alarm 13 through an electrical signal. When the massage intensity exceeds the limit value, the buzzer alarm 13 will sound an alarm. Different limit values ​​can be set to simulate the massage intensity required for different degrees of meibomian gland dysfunction, providing students with a safe and controllable practical environment. The buzzer alarm 13 and the pressure sensor 12 are existing technologies, and the connection method and signal transmission method of the two will not be described in detail in this specification.

[0024] This invention, through the cooperation of pressure sensor 12 and buzzer alarm 13, can simulate the massage intensity required for different degrees of meibomian gland dysfunction. By injecting meibomian gland contents into the lower eyelid 6 and upper eyelid 16, the operation of unblocking the meibomian glands can be simulated. This meibomian gland massage teaching aid simulates the real eye structure and the physiological state of the meibomian glands, highly reproducing the clinical scenario and providing students with a safe and controllable hands-on environment. In addition, the easily detachable facial teaching aid 1 and eye operation belt 2 allow for individual component replacement, reducing teaching and maintenance costs.

[0025] In one alternative implementation, both the upper eyelid 16 and the lower eyelid 6 are provided with a receiving cavity for accommodating the contents of the meibomian gland. The receiving cavity is used to accommodate simulated contents of the meibomian gland, such as a toothpaste-like substance. When students massage, they can massage and squeeze out the injected substance to simulate the operation of unblocking the meibomian gland, which highly replicates the clinical scenario.

[0026] In one alternative embodiment, injection ports 11 are provided on the sides of both the upper eyelid 16 and the lower eyelid 6, and the injection ports 11 facilitate the injection of the meibomian gland contents into the receiving cavity through a needle.

[0027] In one alternative implementation, both the upper eyelid 16 and the lower eyelid 6 are provided with micropores. The micropores simulate the state of real human pores, and their arrangement facilitates the discharge of the contents of the meibomian glands through the micropores during massage, thus better simulating the real scene.

[0028] In one alternative embodiment, the face teaching aid 1 has an eye mounting groove 3 at the eye position, which facilitates the installation of the eye operation belt 2.

[0029] In one alternative implementation, the eye manipulation band 2 is embedded inside the eye mounting slot 3. The embedded design allows the eye manipulation band 2 to be completely embedded in the facial teaching aid 1, with the surfaces of the two flush and aligned to form a complete, smooth, and highly realistic facial contour. In addition, it can also prevent the eye manipulation band 2 from shifting during the massage process.

[0030] In one alternative implementation, positioning holes 10 are provided on both sides of the eye mounting groove 3, and positioning rods 9 are connected to both sides of the eye operation band 2. The design of the positioning holes 10 and positioning rods 9 facilitates quick and easy assembly and disassembly of the eye operation band 2 and the facial teaching aid 1. When replacing, first pull the positioning rods 9 outward. After the positioning rods 9 are completely pulled out from the inside of the positioning holes 10, the eye socket body 5 can be removed from the inside of the eye socket groove 14 and the eye operation band 2 can be removed for replacement.

[0031] In one alternative implementation, the eye operation band 2 is further provided with eyebrows 4, which are located above the eye socket body 5. The eyebrows 4 can not only serve as a positioning reference and guide students' operation, but also enhance the simulation of the teaching aid.

[0032] In one alternative implementation, the front end of the facial teaching aid 1 is connected to a nose 7, which can simulate the facial contours of a real patient and provide spatial positioning and reference for operation.

[0033] In one alternative implementation, eyelashes 15 are connected to both the upper eyelid 16 and the lower eyelid 6. The eyelashes 15 help students clearly identify the eyelid margin and learn how to avoid eyelash interference during operation, thereby improving the accuracy of the operation.

[0034] The meibomian gland massage teaching aid provided in this embodiment operates as follows: The lower eyelid 6 and upper eyelid 16 on the eye operation band 2 are made of silicone simulation material, allowing students to perform key operations such as pulling up, pulling down, and inward and outward turning of the eyelids. During meibomian gland massage, a toothpaste-like substance is injected into the lower eyelid 6 and upper eyelid 16 through the injection port 11 inserted into the syringe. Students can squeeze out the injected substance through micropores during massage. The pressure sensor 12 inside the lower eyelid 6 and upper eyelid 16 can monitor the massage intensity in real time. Once the massage intensity exceeds the set value, an alarm is triggered by the buzzer alarm 13. Students need to operate the eye operation band 2 repeatedly during teaching, which causes the eye operation band 2 to wear out quickly. Therefore, the eye operation band 2 can be removed and replaced separately from the face teaching aid 1. To replace it, first pull the positioning rod 9 outward. After the positioning rod 9 is completely pulled out of the positioning hole 10, the eye socket body 5 is removed from the eye socket groove 14, and then the eye operation band 2 can be removed for replacement.
