Description

Technical Field

[0001] The utility model relates to the technical field of clinical medical care teaching, in particular to a jejunal intubation human body model teaching aid. Background Technique

[0002] Blind nasal jejunal intubation refers to an operation in which a nasal jejunal tube is inserted into the duodenum or jejunum without the aid of any imaging examination instruments during the intubation process. However, although indwelling a nasal intestinal nutrition tube is a basic clinical medical care operation, the intubation process is still difficult for medical staff, especially for those in the novice period.

[0003] Currently, most of the existing medical anatomical model teaching aids only include parts of the oral cavity, esophagus and stomach, and lack models of the intestine below the pylorus. Moreover, most models adopt a solid structure and it is difficult to intuitively and dynamically display the whole process details of nasal jejunal tube insertion, which to a certain extent restricts the effect of jejunal intubation teaching and practical practice. Content of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems in the related technologies to some extent.

[0005] To this end, an object of the utility model is to provide a jejunal intubation human body model teaching aid, which can not only simulate the complete digestive tract structure of the human body from the oral cavity to the jejunum, but also intuitively and dynamically display the whole process of nasal jejunal tube insertion, thereby improving the effect of jejunal intubation teaching and practical practice.

[0006] To achieve the above object, the utility model provides a jejunal intubation human body model teaching aid, including: a human body model, wherein a catheterization channel is arranged inside the human body model, and the catheterization channel simulates the insertion path of a bionic human nasal jejunal tube; both the human body model and the catheterization channel are made of transparent materials.

[0007] For the jejunal intubation human body model teaching aid of the utility model, the insertion path of the bionic human nasal jejunal tube can simulate the whole process of jejunal intubation in detail, and the transparent material can enable medical staff to clearly observe the advancing path of the nasal jejunal tube in the body during explanation, teaching or simulation practice, intuitively and dynamically display the whole process of nasal jejunal tube insertion, thereby improving the effect of jejunal intubation teaching and practical practice.

[0008] In addition, the jejunal intubation human body model teaching aid proposed according to the above application may also have the following additional technical features:

[0010] Specifically, the model head is a bionic human head structure, and the model torso is a bionic human torso structure.

[0011] Specifically, the catheterization channel includes the nasal cavity, pharynx, esophagus, stomach, duodenum, and jejunum. Among them, the nasal cavity and the pharynx are respectively arranged in the model head; the esophagus, the stomach, the duodenum, and the jejunum are connected in sequence from top to bottom and arranged in the model torso, and one end of the esophagus far from the stomach is connected to the pharynx.

[0012] Specifically, the nasal cavity and the pharynx simulate the shape structures of the human nasal cavity and throat.

[0013] Specifically, the shapes of the esophagus, the stomach, the duodenum, and the jejunum respectively simulate the contour shapes of the corresponding parts of the human body.

[0014] Specifically, the insertion path of the bionic human nasointestinal tube refers to the path that sequentially passes through the pharynx, the esophagus, the stomach, and the duodenum from the nasal cavity and reaches the jejunum.

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the solutions of the present utility model will be further described below. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] The jejunal intubation human body model teaching aid according to the embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0025] As Figure 1 shown, the jejunal intubation human body model teaching aid according to the embodiment of the present utility model may include a human body model 1, and an intubation channel 2 is arranged inside the human body model 1. The intubation channel 2 simulates the insertion path of the bionic human nasoenteric tube 4, and both the human body model 1 and the intubation channel 2 are made of transparent materials.

[0026] Among them, it can be understood that the insertion path of the bionic human nasoenteric tube 4 can comprehensively simulate the entire process of inserting the nasoenteric tube 4 (jejunal intubation), and the transparent material can enable medical staff to clearly observe the traveling path of the nasoenteric tube 4 in the body during teaching or insertion, and intuitively and dynamically display the entire process of inserting the nasoenteric tube 4, thereby improving the effect of jejunal intubation teaching and practical practice.

[0027] It should be noted that the transparent material described in this embodiment can be PVC (Polyvinyl chloride), a widely used plastic material with good transparency and durability, or a transparent silicone material, which has excellent transparency, excellent flexibility and biocompatibility, and can more realistically simulate the touch of human tissues, further enhancing the realism of teaching and practical exercises.

[0028] In an embodiment of the present utility model, as Figure 1 shown, the human body model 1 includes a model head 10 and a model torso 11.

[0029] Among them, the model head 10 is rotatably arranged on the model torso 11, and the model head 10 is communicated with the model torso 11, capable of simulating the turning of the human head. Both the model head 10 and the model torso 11 are hollow structures.

[0030] It can be understood that the design of the hollow structure not only provides a accommodating space for the catheterization channel 2, but also reduces the material usage, to a certain extent reducing the manufacturing cost. At the same time, this design also makes the human body model 1 lighter and easier to carry.

[0031] Furthermore, as Figure 1 shown, the model head 10 is a bionic human head structure, and the model torso 11 is a bionic human torso structure. The bionic design makes the model head 10 and the model torso 11 highly restore the real human body in terms of morphology, including the proportion of facial features of the head, the morphology of the skull, and the muscle distribution and bone structure of the torso. This realism helps trainees better understand and remember the human body structure on the one hand, and enables trainees or medical staff to intuitively observe the structure and relationship of various parts of the human body on the other hand, enhancing the teaching effect and providing a more realistic simulation operation environment.

[0032] In an embodiment of the present utility model, as Figure 1 shown, the catheterization channel 2 includes a nasal cavity 20, a pharynx 21, an esophagus 22, a stomach 23, a duodenum 24, and a jejunum 25.

[0033] Among them, the nasal cavity 20 and the pharynx 21 are respectively arranged in the model head 10, and the esophagus 22, the stomach 23, the duodenum 24, and the jejunum 25 are arranged in the model torso 11 in a sequentially communicating manner from top to bottom. Among them, one end of the esophagus 22 far from the stomach 23 is communicated with the pharynx 21.

[0034] Specifically, the arrangements of the nasal cavity 20, pharynx 21, esophagus 22, stomach 23, duodenum 24, and jejunum 25 exactly follow the real digestive tract structure of the human body. The series of channel designs enable the model to highly simulate the real insertion path of the nasointestinal tube 4. By highly simulating the real human physiological structure, it provides a near-real operation environment for medical staff and trainees, thus enhancing the authenticity of teaching and practice.

[0035] Furthermore, as Figure 1 shown, the nasal cavity 20 and pharynx 21 simulate the shape structures of the nasal cavity and pharynx of the human body. The nasal cavity 20 and pharynx 21 that simulate the real shapes of the nasal cavity and pharynx enable trainees to intuitively feel the morphological and structural characteristics of these parts of the human body during observation and operation. This intuitiveness helps trainees understand and master relevant knowledge more quickly, improve learning effects, and when conducting clinical skills training such as the insertion of the nasointestinal tube 4, the nasal cavity 20 and pharynx 21 that simulate the real shapes of the nasal cavity and pharynx can provide a more real operation environment, enabling medical staff or trainees to practice repeatedly in this environment, and thus becoming more familiar with and mastering the skills and key points in actual operation.

[0036] Furthermore, as Figure 1 shown, the shapes of the esophagus 22, stomach 23, duodenum 24, and jejunum 25 respectively simulate the contour shapes of the corresponding parts of the human body. This high degree of simulation not only improves the teaching effect but also enhances the realism of practical operation, helping trainees understand and master the structure of the human digestive system more intuitively.

[0037] Exemplarily, the shape of the esophagus 22 can be the contour shape of the human esophagus, the shape of the stomach 23 can be the contour shape of the human stomach, and the shapes of the duodenum 24 and jejunum 25 can be the contour shapes of the human duodenum and human jejunum respectively.

[0038] In an embodiment of the present utility model, as Figure 1 shown, the insertion path of the bionic human nasointestinal tube refers to the path that sequentially passes through the pharynx 21, esophagus 22, stomach 23, and duodenum 24 from the nasal cavity 20 downwards to reach the jejunum 25.

[0039] Specifically, the above insertion path of the bionic human nasointestinal tube fully simulates the real insertion path of the nasointestinal tube 4 clinically. By simulating the complete catheterization path, the teaching and practice processes become more coherent and complete. Trainees can start from the nasal cavity 20 and gradually go deeper to understand the operation key points and precautions at each stage, thus establishing a clear understanding of the entire catheterization process. Through repeated catheterization operation practice on the human body model 1, medical staff can more proficiently master the skills of inserting the nasointestinal tube 4 and improve the accuracy and success rate of the operation.

[0040] In another embodiment of the present utility model, as Figure 2 shown, a first marking position 230, a second marking position 231, and a third marking position 250 are arranged on the mannequin 1 from top to bottom.

[0041] Among them, it can be understood that the design of the first marking position 230, the second marking position 231, and the third marking position 250 can clearly indicate the key positions on the mannequin 1, which is very helpful for trainees or medical staff to quickly locate these key positions during the operation. At the same time, during the teaching process, teachers can also accurately explain and demonstrate relevant operations through these marking positions. Trainees can also better understand and remember the operation steps and key points by observing these marking positions, thereby improving the accuracy and effect of teaching.

[0042] Furthermore, as Figure 2 shown, the above-mentioned jejunal intubation mannequin teaching aid may further include a sternum 3. The sternum 3 is arranged in the model trunk 11, and the sternum 3 is arranged above the esophagus 22. The sternum 3 is made of a transparent material. At the lower end of the sternum 3, and at the included angle of the two costal arches of the sternum 3, a xiphoid process 30 is provided.

[0043] Among them, it can be understood that the sternum 3 is made of a transparent material, so that trainees or medical staff can clearly observe the structure of the esophagus 22 below the sternum 3, and it is convenient to observe the direction and insertion process of the nasointestinal tube 4. This intuitiveness is more helpful for teaching and learning.

[0044] The model head 10 is rotated counterclockwise by 90°. Relevant personnel can manually rotate the model head 10 so that the model head 10 is rotated counterclockwise by 90°, making the nasal cavity 20 face upward, that is, facing the ceiling of the ward or laboratory.

[0045] When the nasal cavity 20 faces upward, the position length from the hairline of the forehead to the xiphoid process 30 is the first marking position 230. When the insertion end of the nasointestinal tube 4 is placed at the first marking position 230, and then the nasointestinal tube 4 is further advanced 25 cm, the insertion position is the second marking position 231. When the nasointestinal tube 4 is further advanced 25 cm again, the insertion position is the third marking position 250.

[0046] Among them, the first marking position 230 can help medical staff determine the initial depth at which the nasointestinal tube 4 enters the body from the nasal cavity 20. This position ensures that the nasointestinal tube 4 can smoothly enter the stomach 23.

[0047] The second marking position 231 is when the nasointestinal tube 4 is inserted to the first marking position 230 and then advanced 25 cm. This usually corresponds to the vicinity of the pylorus of the stomach 23. The function of this marking position is to help medical staff confirm whether the nasointestinal tube 4 has passed through the pylorus and is ready to enter the duodenum 24.

[0048] The third marking point 250 is 25 cm further from the second marking point 231, which generally means that the nasoenteric tube 4 has entered the jejunum 25 region, ensuring that the nasoenteric tube 4 can be accurately placed at the intestinal position where nutritional support or drug delivery is required.

[0049] By setting clear first marking point 230, second marking point 231, and third marking point 250, it provides an accurate depth reference for the insertion of the nasoenteric tube 4, which helps medical staff to accurately control the depth of the nasoenteric tube 4 entering the body during the operation, avoiding complications caused by being too deep or too shallow. At the same time, the settings of the first marking point 230, second marking point 231, and third marking point 250 also make the entire insertion process more intuitive and understandable. Medical staff can clearly see the position of the nasoenteric tube 4 at different marking points, thus more accurately judging whether it has entered the target area. Moreover, in teaching or training, these marking points also provide clear operation guidance for trainees.

[0050] In summary, the jejunum intubation human model teaching aid of the embodiment of the present utility model can not only simulate the complete digestive tract structure of the human body from the oral cavity to the jejunum, but also intuitively and dynamically display the entire process of nasoenteric tube insertion, improving the teaching and practical training effects of jejunum intubation.
