Description

Technical Field

[0001] This utility model relates to the field of medical teaching aids, and in particular to a meibomian gland model. Background Technology

[0002] Meibomian glands are a group of glands located in the eyelids. They are mainly responsible for secreting lipid components of the eyelids to form the lipid layer in the tear film. Their function is to keep the surface of the eye lubricated, reduce the evaporation rate of tears, and protect the eyes from external irritation and infection. The structure of meibomian glands is complex and they are usually tubular.

[0003] Most existing meibomian gland models are displayed in a fixed position, which makes it inconvenient to simultaneously open the eyelids for display and squeeze out the glands, affecting the demonstration effect. In addition, the height of some models is fixed, which makes it difficult to adjust according to the needs of use, hindering observation and research, and thus reducing their practicality.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] In use, the support component is fixed on a table or other structure. The demonstration component is adjusted to a suitable height by the support component. The eyeball demonstration element and the eyelid edge demonstration element can be opened for direct observation. The lower eyelid demonstration element can also be used to display tissue structure by squeezing out the demonstration element.

[0030] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] Figures 1 to 5 A meibomian gland model according to an embodiment of the present invention includes:

[0033] Support component 2 has an adsorption element at the bottom and a demonstration component 1 that can be detached at the top. The height of support component 2 can be adjusted to move support component 2 up and down.

[0034] Demonstration component 1 includes an eyeball demonstration element 11, which is partially covered by an eyelid edge demonstration element 12. The eyelid edge demonstration element 12 is provided with several gland demonstration elements 13. The upper eyelid demonstration element 14 and the lower eyelid demonstration element 15 are combined into an openable shell that encloses the eyeball demonstration element 11, the eyelid edge demonstration element 12 and the gland demonstration elements 13.

[0035] Specifically, one end of the upper eyelid demonstration element 14 and the lower eyelid demonstration element 15 are hinged together to form a shell-like opening and closing structure that encloses the eyeball demonstration element 11.

[0036] In some embodiments, both the upper eyelid demonstration element 14 and the lower eyelid demonstration element 15 are provided with connecting ends that can be movably connected to the support assembly 2. This design is to flexibly flip the upper and lower relationship of the two eyelid demonstration elements to meet the purpose of demonstration and teaching.

[0037] Furthermore, the connecting end is one or a combination of magnetic elements, threaded elements, and socket elements. This design enables a quick, easy, and secure connection between the upper eyelid demonstration element 14 and the lower eyelid demonstration element 15 and the movable column.

[0038] The upper eyelid demonstration element 14, the eyelid edge demonstration element 12, and the lower eyelid demonstration element 15 are made of elastic material. For better simulation, an element that imitates an eyelash 16 can be provided at the end of the upper eyelid demonstration element 14 and the lower eyelid demonstration element 15 away from the connection point. By determining the position of the eyelash 16, the relative position between the eyelid edge demonstration element 12 and the gland demonstration element 13 can be better demonstrated.

[0039] The lower eyelid demonstration element 15 forms several channels 151, and an extrusion demonstration element is provided in the channel 151. Pressing the lower eyelid demonstration element 15 causes the extrusion demonstration element to extend out of the channel 151.

[0040] The channels 151 are evenly spaced, and the extrusion demonstration elements are used to simulate the three-dimensional position of the glands in the eyelids. The extrusion demonstration elements can be connected to the blind end of the channel 151 by a spring, extending when squeezed and rebounding when released. The extrusion demonstration elements can be set to be transparent or slightly milky white, and some groups are set to be foamy oil. This is because the oil secreted by the meibomian glands is normally transparent or slightly milky white and has a greasy texture. Some patients with meibomian gland inflammation or other eye infections will secrete foamy glands, which facilitates the explanation and demonstration according to different gland conditions and improves the demonstration effect.

[0041] In use, when the lower eyelid demonstration element 15 is on top, multiple sets of extruded demonstration elements can be extruded and displayed along the channel 151. When the upper eyelid demonstration element 14 is on top, the upper eyelid demonstration element 14 can be flipped open, which is equivalent to flipping the eyelid upward. After the upper eyelid demonstration element 14 is opened, the gland demonstration element 13 and the eyelid edge demonstration element 12 are exposed. The distribution of the gland demonstration element 13 on the eyelid edge demonstration element 12 and the upper eyelid demonstration element 14 can be displayed, and the gland demonstration elements 13 can be seen one by one on the top. When not in use, the lower eyelid demonstration element 15 and the upper eyelid demonstration element 14 will be closed by elastic recovery.

[0042] Optionally, the support assembly 2 includes a base 21, a fixed rod 22, a movable rod 23, and a tensioning element 24. The suction cup is disposed on the ground of the base 21, the fixed rod 22 is fixed to the top surface of the base 21, the movable rod 23 moves up and down relative to the fixed rod 22, and the tensioning element 24 is arranged perpendicular to the direction of movement of the movable rod 23. The movement of the tensioning element 24 allows or restricts the movement of the movable rod 23 relative to the fixed rod 22.

[0043] Specifically, a square groove is provided on one side of the movable rod 23, and a slider is provided in the square groove. A locking block is fixed on the other side of the slider, and a threaded rod is inserted into the locking block. The threaded rod is rotatably set on the fixed rod 22. Rotating the threaded rod pushes the locking block closer to or away from the movable rod 23. When it gets closer, the friction force between the locking block and the movable rod 23 increases, eventually exceeding the downward force of the movable rod 23, thereby achieving the effect of fixing the movable rod 23 at a certain position on the fixed rod 22. The locking block and the threaded rod form a tensioning element 24.

[0044] Optionally, the eyelid edge demonstration element 12 and the gland demonstration element 13 are detachably connected to the eyeball demonstration element 11.
