Description

Technical Field

[0001] This utility model relates to the field of human anatomy and neurology research technology, specifically to a three-dimensional human body model of the body surface area innervated by spinal nerves. Background Technology

[0002] Spinal nerves have always been a challenging yet crucial area in clinical learning, especially in the teaching and practice of neurology and anatomy. Accurately understanding the distribution of spinal nerves is essential for medical students and clinicians. Existing diagrams of spinal nerve innervation areas are mostly two-dimensional, failing to accurately represent the three-dimensional spatial structure of the spinal nerves and their relationships with other parts of the body. This lack of depth prevents learners from intuitively understanding the distribution and interweaving of spinal nerves in the body, making accurate judgments difficult in practical applications. Furthermore, most spinal nerve distribution diagrams only use different colors to indicate the innervation areas of each nerve, without clearly defined corresponding surface landmarks. This lack of clear and intuitive surface reference marks makes it difficult for learners to accurately compare the diagrams with the actual human body during practical operations, increasing the difficulty of learning and memorization, especially in clinical diagnosis and treatment.

[0003] A utility model patent with announcement number CN215679802U discloses a human spinal nerve assessment teaching model. This existing technology has two significant drawbacks: First, the spinal nerve segment regions are located within the head area (i.e., within a texture map, as the texture map shows multiple muscle regions arranged according to the human body's muscle structure). When teaching is activated, the spinal nerve segment regions are not presented in a three-dimensional manner; the overall presentation remains planar, lacking realism and intuitiveness. Second, when teaching is activated, the LED lights are turned on, and the brightness diffuses through each area, causing dizziness, especially for students who are far from the human model or those with astigmatism or myopia, making it difficult to distinguish the spinal nerves in each area, resulting in a lack of in-depth understanding of the spinal nerves. Utility Model Content

[0004] To address the aforementioned issues of two-dimensional display methods and light interference, this invention aims to provide a three-dimensional human body model of the spinal nerve innervation area. The device of this invention combines three-dimensional design, light source isolation, and an optimized light-emitting control system, enabling learners to more intuitively understand and memorize the distribution and function of spinal nerves.

[0005] The main idea of ​​the technical solution adopted in this utility model is as follows: This model independently separates each spinal nerve innervation area using an opaque partition, avoiding light source interference between different areas. The opaque partition is made of composite material to ensure independent light effects without leakage or crosstalk. Furthermore, light emitters are installed at key points in each area. The switching, brightness, and flashing mode of the light emitters are controlled by a wireless remote control, thus intuitively demonstrating the distribution of spinal nerves. The three-dimensional structure overcomes the shortcomings of two-dimensional diagrams, helping learners to realistically and intuitively understand the spatial distribution of spinal nerves and their relationship with other parts of the body. The optimized light source design effectively avoids light pollution and improves teaching effectiveness.

[0006] The technical objective of this utility model is achieved through the following technical solution:

[0007] A three-dimensional human body model of a spinal nerve innervation area includes a three-dimensional human body model body, which is divided into multiple spinal nerve innervation areas. The model is characterized in that adjacent spinal nerve innervation areas are separated by opaque partitions, and each spinal nerve innervation area has a light-emitting body at its sensory key point.

[0008] To achieve the above technical solution, the opaque partition is further made of composite partition.

[0009] Furthermore, the composite isolation plate includes a first isolation layer and a second isolation layer, with the two first isolation layers respectively disposed on both sides of the second isolation layer, and the second isolation layer (32) being an optical black glue layer or a black flocking layer.

[0010] Furthermore, the light source is a light source capable of producing different light emission colors in two adjacent regions.

[0011] By adopting the above technical solution, this utility model has the following technical effects:

[0012] By using opaque partitions, each spinal nerve innervation area can be effectively isolated, avoiding light interference and crosstalk between different areas. The partition design ensures independent lighting effects for each area and prevents light leakage to adjacent areas, thereby improving the model's accuracy and optical isolation.

[0013] By installing light-emitting devices, especially at the sensory key points in each spinal nerve innervation area, learners can visually observe these key points. The color, brightness, and flashing pattern of the light-emitting devices can be adjusted via a wireless remote control, further enhancing the visualization of spinal nerve areas and helping learners understand the distribution and function of spinal nerves more clearly and accurately.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments, not all embodiments.

[0021] refer to Figures 1-4 This application discloses a three-dimensional human body model of a spinal nerve innervation region, including a three-dimensional human body model body 1. The three-dimensional human body model body 1 is divided into multiple spinal nerve innervation regions 2. Each spinal nerve innervation region 2 is separated by an opaque partition 3, and each spinal nerve innervation region 2 has a light-emitting element 4 at its sensory key point. The opaque partition 3 is a composite partition. The composite partition includes a first partition layer 31 and a second partition layer 32, with the two first partition layers 31 respectively disposed on both sides of the second partition layer 32.

[0022] Specifically, the three-dimensional human body model 1 is made of a high-strength plastic material, possessing sufficient rigidity and stability to simulate the shape and anatomical features of the human body. The external surface of the model presents the complete shape of the human body, clearly displaying skeletal structure features, human landmarks, and key muscle features.

[0023] Specifically, skeletal structural features and human landmarks, including the clavicle, nipples, occipital tuberosity, umbilicus, groin, and xiphoid process, can more accurately locate the areas innervated by spinal nerves. Key muscle features include the upper trapezius, deltoid, biceps brachii, brachialis, extensor carpi radialis longus and brevis, triceps brachii, flexor digitorum proprioception, abductor digiti minimi, iliopsoas, quadriceps femoris, tibialis anterior, extensor hallucis longus, gastrocnemius, and soleus, which facilitate learners' memorization of the muscle contractions innervated by each spinal nerve.

[0024] like Figure 1 The three-dimensional human body model 1 is divided into 25 spinal nerve innervation regions 2. Each spinal nerve innervation region 2 includes one or two sensory key points. The correspondence between each region and its sensory key points is shown in Table 1.

[0025] Table 1 Spinal Nerve Function Assessment Form

[0026]

[0027]

[0028] Specifically, each of the 25 spinal nerve innervation areas 2 is covered with a film or coating of a different color. These films or coatings use high-quality medical-grade color materials to provide clear and durable color differentiation. The film material is typically a highly transparent plastic film, while the coating uses environmentally friendly and non-toxic paints or spraying materials to ensure that it will not fade or have adverse effects on human health during long-term use. The color selection for each area is based on the classification of spinal nerves and their functional characteristics in human anatomy, ensuring intuitive visual identification.

[0029] Preferably, each area innervated by a spinal nerve is equipped with a light-emitting element 4 at a sensory key point. Each light-emitting element 4 is a small LED light, capable of providing sufficient brightness with low power consumption, ensuring clear visibility even in low ambient light conditions. The emission color of all light-emitting elements 4 is consistent with the color of the film or coating attached to that area; for example, red is used for the upper limb area, blue for the spinal spine area, and green for the lower limb area. In this way, users can quickly identify the corresponding spinal nerve innervation area 2 by the color of the light-emitting element 4, achieving better teaching and demonstration effects.

[0030] Specifically, all the light-emitting elements 4 on the spinal nerve innervation areas 2 are uniformly controlled by a wireless external remote controller. This wireless external remote controller is a 5050RGB controller, which is a currently known technology. The 5050RGB controller can conveniently and quickly control the switching, brightness adjustment, and flashing mode of the light-emitting elements 4 in different areas of the model, thereby improving the efficiency and operability of the three-dimensional human body model body 1.

[0031] It is worth noting that each light-emitting element 4 has a built-in receiver module, which can receive signals from the wireless remote control. This wireless communication technology allows for unified or independent control of all light-emitting elements 4 in the model. The signals emitted by the remote control are received by the receiver module via a wireless transmission system (e.g., RF or infrared technology), and the module controls the on / off state and other related parameters of each light-emitting element 4 according to the signal commands.

[0032] likeFigure 3 Adjacent spinal nerve innervation regions 2 are separated by opaque septa 3 to ensure that the light effect within each spinal nerve innervation region 2 does not interfere with that of neighboring regions. The opaque septa 3 are arranged along the edge contour line of each spinal nerve innervation region 2, and the edge contour of each region 2 is precisely calculated and defined using 3D modeling software based on anatomical knowledge. This contour line reflects the actual boundary of spinal nerve innervation, allowing the luminescent body 4, opaque septa 3, and other structures within each region to accurately correspond to the nerve function of that region.

[0033] Preferably, on the model surface, the edge contour lines are represented in the form of visible grooves, facilitating the installation of the opaque partition 3. These lines not only help to construct precise area boundaries but also serve as fixing reference points for the partition, ensuring a tight fit between the partition and the model surface.

[0034] Specifically, the shape of the opaque partition 3 is designed and cut according to the edge contour line of each spinal nerve innervation area 2. The shape and size of the opaque partition 3 are customized according to the size of each area. The design of the partition must ensure that it can fit precisely along the edge contour line to avoid any light leakage or light pollution from adjacent areas.

[0035] Preferably, at the edge contour line of each spinal nerve innervation region 2 of the model, an opaque partition 3 is securely installed in place using a specialized fixing method. During installation, industrial-grade adhesives or a dedicated slot design can be used to ensure a tight bond between the partition and the surface of the three-dimensional human body model 1. Furthermore, it is necessary to ensure that each partition seamlessly connects at the edge of the region to avoid light leakage.

[0036] like Figure 4 To improve optical isolation performance and structural stability, the opaque partition 3 employs a composite partition. The composite partition consists of two layers of different materials, providing excellent optical isolation. It comprises a first isolation layer 31 and a second isolation layer 32, with the first isolation layer 31 located on the outer side and the second isolation layer 32 on the inner side. This design aims to maximize optical isolation and ensure that light sources within each area do not affect the luminous efficiency of adjacent areas.

[0037] Specifically, the first isolation layer 31 is made of an opaque material, such as dark plastic or film, which can effectively block the light emitted by the light source from scattering outward. The first isolation layer 31 has a strong light blocking ability, preventing crosstalk between light sources in different areas, thereby ensuring that the light emitter 4 in each spinal nerve innervation area 2 can function independently without affecting each other.

[0038] Specifically, the second isolation layer 32 is located inside the first isolation layer 31 and is typically made of light-absorbing materials, such as optical black glue or black flocking. This layer can absorb the weak light leaking through the first isolation layer 31, further enhancing the optical isolation effect. The second isolation layer 32 improves the light absorption and scattering efficiency, ensuring that the light source in each area remains independent and avoiding light pollution in adjacent areas caused by light reflection or scattering.

[0039] The workflow of this embodiment is as follows:

[0040] First, a three-dimensional human body model is created using 3D printing technology or other manufacturing processes 1, ensuring that the model accurately represents the distribution and innervation areas of the human spinal nerves. Based on the distribution of the spinal nerves, the model is divided into multiple spinal nerve innervation areas 2. These areas are defined according to the physiological location and anatomical characteristics of the spinal nerves, ensuring that the boundaries and functional distribution of each area are reasonable.

[0041] To ensure independent light effects between different spinal nerve innervation regions 2, opaque partitions 3, including composite partitions, were designed and fabricated. Based on the anatomical distribution of the spinal nerve innervation regions 2 in the model, the edge contour lines of each region were determined. These contour lines will serve as the reference for installing the opaque partitions 3. The opaque partitions 3 were precisely installed along the edge contour lines of the spinal nerve innervation regions 2, ensuring no light leakage between each region. The partitions were securely fixed in their respective positions, forming independent light effect zones.

[0042] Light-emitting elements 4, such as LEDs, are installed at the sensory key points of each spinal nerve innervation area 2. These light-emitting elements 4 are consistent in color with the spinal nerve innervation area 2, and each light-emitting element 4 is ensured to have an independent color, distinct from the light-emitting elements 4 in adjacent areas. The light-emitting elements 4 are connected to a power supply and control system to ensure normal operation. The brightness, on / off state, etc., of the light-emitting elements 4 will be controlled by a remote control system.

[0043] An external remote control is configured to control the on / off state, brightness, and flashing mode of each light emitter 4 via wireless communication (such as RF or infrared). Users can use the remote control to turn the light emitter 4 on or off in a specific spinal nerve innervation area 2, adjust the brightness, or select the flashing mode. The receiving module inside the light emitter 4 receives commands from the remote control via wireless signals and executes the corresponding operations. The wireless remote control can control the light emitters 4 in one or more areas, adjusting the display effects in different areas.
