[0001] This invention relates to the field of medical teaching model technology, specifically to an interactive human anatomical head and neck venous return model and its display method. Background Technology
[0002] In teaching human anatomy, the venous return system of the head and neck is a complex and important part. Its pathways, anastomoses, and connections with intracranial structures are both key points and challenges in teaching. Traditional teaching models are mostly static wall charts or plastic models, which cannot dynamically and intuitively demonstrate the direction of blood flow, let alone simulate the process of blood backflow leading to intracranial infection under pathological conditions.
[0003] In the existing technology, there are some anatomical models that use light to demonstrate, but most of them can only achieve simple lighting or flashing, and cannot accurately simulate the directional flow of blood in complex venous networks.

[0025] A second aspect of the present invention provides a method for displaying an interactive human anatomical head and neck venous return model as described in the first aspect, comprising the following steps:
[0026] Startup steps: Turn on the model power, initialize the system through the control module, and enable the touch screen to enter the user interface;
[0027] Mode selection steps: In response to the user's selection on the user interface, enter the overall process mode, single-segment process mode or clinical case mode;
[0028] Process demonstration steps:
[0029] When entering the overall process mode, the control module controls all the LED flexible light strips simulating veins in the main body of the model to light up sequentially and present a directional blue flowing light according to the physiological path and direction of venous return in the head and neck.

[0031] Interactive demonstration steps:
[0032] When entering the clinical case mode and selecting a facial infection case, in response to the touch of the first pressure sensor in the danger triangle area of the model's face, the control module controls the LED flexible light strips in the direction of the facial vein, inner canthal vein, and superior and inferior ophthalmic veins to emit light in the opposite direction, and triggers the voice module to play the corresponding pathological description.
[0033] When entering the clinical case mode and selecting a scalp infection case, in response to the touch of the second pressure sensor on the scalp area of the model body, the control module controls the LED flexible light strips in the direction of the scalp veins and diploic veins to emit light flowing in the opposite direction, and triggers the voice module to play the corresponding pathological description.

[0036] 1. This invention uses programmable LED flexible light strips to simulate the directional flow of blood in a venous network, transforming static anatomical structures into dynamic physiological processes, making teaching more intuitive. The control module, through the user interface design of the LCD screen, organizes the structure into a flowchart according to the spatiotemporal sequence of venous return, serving as a guide for students' self-study; on the other hand, the text buttons on the LCD screen can independently control the on / off state, flow direction, and timing of each light strip, thereby dynamically demonstrating the direction of venous blood flow and enhancing the teaching effect.
[0037] 2. This invention, by setting pressure sensors in the danger triangle and on the scalp, can simulate the pathological process of blood flowing back into the cranium due to facial and scalp infections, closely integrating anatomical knowledge with clinical practice and improving the teaching and demonstration effect.
[0038] 3. This invention combines visual and auditory stimulation with flowing light and voice explanation, which helps learners deepen their understanding and memory. The user interface is simple and clear, making it very suitable for classroom teaching and self-study. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0045] like Figure 1-2 As shown, an interactive human anatomical head and neck venous return model includes:
[0046] Model body 1, which is a head and neck model, is made of at least partially transparent material to reveal the internal structure, and is generally made of transparent silicone.
[0047] The control base 2, on which the model body 1 is mounted; the control base 2 includes a shell, and a touch screen 6, a power switch 11 and a USB interface 10 mounted on the shell; the control base 2 contains a control module 7, a power supply module 8 and a voice module 9.
[0048] Multiple flexible LED light strips 3 are housed inside the model body 1. Each flexible LED light strip 3 is arranged and connected according to the actual anatomical path of the head and neck veins to simulate different veins.
[0049] The model body 1 has a first pressure sensor 4 installed below the triangular area from the root of the nose to both sides of the corners of the mouth, and a second pressure sensor 5 installed below the scalp area.
[0050] The multiple flexible LED light strips 3, the first pressure sensor 4, the second pressure sensor 5, the touch screen 6, the power supply module 8, and the voice module 9 are all electrically connected to the control module 7.
[0051] The control module 7 is configured to independently control the opening and closing of each of the LED flexible light strips 3, as well as the direction and timing of the light flow, in order to dynamically simulate the flow of blood in veins.
[0052] In this design, the main body of the model 1 is made of partially transparent material, housing multiple flexible LED light strips 3. These light strips are arranged according to the actual anatomical pathways of the veins in the head and neck to simulate venous vessels. The control module 7 independently controls the on / off state of each LED light strip, as well as the direction and timing of light flow, thereby dynamically simulating blood flow in the veins. The dynamic lighting effects simulate blood flow, making the venous return process more intuitive and understandable. Users can interact with the model via a touchscreen and pressure sensors. Furthermore, the main body of the model 1 has first and second pressure sensors 5 located below the danger triangle area of the face and the scalp area, respectively, to detect user touch pressure. The LEDs then provide different lighting effects based on the touch pressure signal, enhancing the learning experience.
[0053] In practical applications, the veins simulated using LED flexible light strips 3 include, but are not limited to: the brachiocephalic vein, internal jugular vein, dural sinus, cavernous sinus, superior and inferior ophthalmic veins, pterygoid venous plexus, deep facial vein, common facial vein, facial vein, medial canthal vein, subclavian vein, external jugular vein, retromandibular vein, scalp veins, and diploic veins. This covers the major venous systems of the head and neck, ensuring the comprehensiveness and anatomical accuracy of the model.
[0054] In practical applications, such as Figure 3 As shown, the control module 7 is configured to provide a graphical user interface (GUI) via the touchscreen display 6. The GUI includes a venous return flowchart, where the graphical elements corresponding to the simulated veins are set as operable virtual buttons. The user interface is user-friendly, simplifying the operation process. Users can directly select specific veins for learning through the flowchart, enhancing the model's interactivity and accessibility.
[0055] In practical applications, such as Figure 3 As shown, the graphical user interface also includes virtual buttons for controlling the display modes: "Overall Process," "Single Segment Process," and "Reset." It provides multiple learning modes, allowing users to view the overall venous return or focus on a single venous segment as needed, improving learning flexibility. The "Reset" function facilitates quick restoration to the initial state, making repeated demonstrations and teaching convenient.
[0056] In practical applications, such as Figure 3 As shown, the control module 7 is configured to: respond to the touch operation of the "overall process" virtual button, control all the LED flexible light strips 3 to emit flowing light simulating blood flow according to the venous return path and a preset timing and direction; respond to the touch operation of a specific vein virtual button after touching the "single segment process" virtual button, control the LED flexible light strip 3 corresponding to the specific vein to change its display state; and respond to the touch operation of the "reset" virtual button, control all the LED flexible light strips 3 to return to their initial display state.
[0057] In practical applications, the voice module 9 is used to store and play voice information; the control module 7 is configured to simultaneously trigger the voice module 9 to play a voice description related to a specific vein when the display state of the LED flexible light strip 3 corresponding to that vein is changed. This provides a multi-sensory learning experience, combining visual and auditory feedback to deepen the user's memory of anatomical structures.
[0058] In practical applications, the control module 7 is configured to: respond to the first pressure sensor 4 being pressed, control the LED flexible light strip 3 corresponding to the facial vein, inner canthal vein, ophthalmic vein and cavernous sinus to produce a reverse flow light effect, and trigger the voice module 9 to play an explanation about facial infection leading to intracranial infection;
[0059] In response to the second pressure sensor 5 being pressed, the LED flexible light strips 3 corresponding to the scalp veins, diploic veins, and dural sinuses are controlled to produce a reverse-flowing light effect, and the voice module 9 is triggered to play an explanation about scalp infection leading to intracranial infection. For example... Figure 4 As shown, clicking "Clinical Case Description" on the graphical user interface displays a pathological description, simulating a clinical pathological scenario and enhancing the model's interactivity.
[0060] In practical applications, the power supply module 8 includes a lithium battery and a charging management module. The USB interface 10 is used to connect an external power source to charge the lithium battery, and the power switch 11 is used to control the power on and off of the entire model. Lithium battery power makes the model portable, eliminating the need for a fixed power source, and suitable for mobile teaching or exhibitions.
[0061] In practical applications, the flexible LED light strip 3 is selected according to the different thicknesses of the simulated veins. This improves the anatomical realism of the model, makes the proportions of vein size more consistent with reality, and enhances learning accuracy.
[0062] Another aspect of the present invention provides a method for displaying an interactive human anatomical head and neck venous return model, comprising the following steps:
[0063] Startup steps: Turn on the model power, initialize the system through the control module 7, and enable the touch screen 6 to enter the user operation interface;
[0064] Mode selection steps: In response to the user's selection on the user interface, enter the overall process mode, single-segment process mode or clinical case mode;
[0065] Process demonstration steps:
[0066] When entering the overall process mode, the control module 7 controls all the LED flexible light strips 3 simulating veins in the main body 1 of the model to light up in sequence and present a directional blue flowing light according to the physiological path and direction of venous return in the head and neck.
[0067] When entering the single-segment process mode, the control module 7 responds to the user's touch of the virtual button for a specific vein name on the interface, and controls one or more LED flexible light strips 3 corresponding to that vein to light up individually or display flowing light.
[0068] Interactive demonstration steps:
[0069] When entering the clinical case mode and selecting a facial infection case, in response to the touch of the first pressure sensor 4 in the dangerous triangle area of the face of the model body 1, the control module 7 controls the LED flexible light strip 3 in the direction of the facial vein, inner canthal vein, and superior and inferior ophthalmic veins to emit light flowing in the opposite direction, and triggers the voice module 9 to play the corresponding pathological description.
[0070] When entering the clinical case mode and selecting a scalp infection case, in response to the touch of the second pressure sensor 5 on the scalp area of the model body 1, the control module 7 controls the LED flexible light strip 3 in the direction of the scalp veins and diploic veins to emit light flowing in the opposite direction, and triggers the voice module 9 to play the corresponding pathological description.
[0071] Reset Step: In response to the user's reset operation, the control module 7 controls all LED flexible light strips 3 to turn off or return to their initial state.
[0072] In summary, the interactive human anatomical head and neck venous return model of the present invention, through the combination of hardware and software such as LED light strips, sensors, control module 7, and touch display screen 6, realizes dynamic and interactive simulation of head and neck venous return, enhances the intuitiveness of learning, and is suitable for medical education, clinical training and public health popularization.
