The four-function acupoint model for the head is a professional simulation teaching aid used for acupuncture teaching and skills training. Through visual and functional design, it helps learners understand the anatomical positions and clinical action principles of acupoints on the head.

This model is based on the anatomical structure of the head, marking the positions of the main acupoints. At the same time, it distinguishes acupoints with different functions, such as pain relief, calming the mind, promoting blood circulation or opening the orifices, through different colors or markings. The interior of the model can simulate skin, muscles and superficial bones, allowing trainees to feel the real resistance changes when practicing acupuncture, thereby mastering the depth and Angle of needle insertion.

In principle, this model combines the theories of anatomy and acupuncture. Through touchable acupoint markings and simulated tissue layers, it enables learners to intuitively understand the location of acupoints and their relationship with surrounding structures. Meanwhile, the model design emphasizes the concept of "four functions", that is, through the stimulation of different acupoints, it acts on clinical functions such as pain relief, calming the mind, promoting blood circulation and opening orifices, enabling trainees to establish the connection between acupoint functions and acupuncture techniques during operation training.

In addition, this model supports repetitive practice, has high security, and can be used in classroom teaching, skills assessment, and self-study training. It not only enhances the intuitiveness of learning but also ensures the standardization of operation. Through the four-function acupoint model of the head, learners can better understand the operational principles of head acupuncture and lay a solid foundation for clinical application.

The Fourteen Meridian Point model is a simulation teaching aid used for acupuncture teaching and training. By visually presenting the fourteen meridians and main acupoints of the human body, it helps learners master the location of acupoints and the distribution of meridians. During the usage process, the following points should be noted to ensure the teaching effect and the service life of the model.

First of all, before operation, the integrity of the model should be checked to ensure that the acupoint markings are clear and that the joints, meridian lines and additional structures are undamaged. The disassemblable model should ensure that the interface is stable and avoid loosening during demonstration or practice.

Secondly, when practicing needling, special teaching needles should be used to avoid using real needles that may cause damage to the model. Students should master the method of gently inserting needles, follow the Angle and depth of needle insertion at the acupoints, and prevent repeated forceful operations from causing surface wear or cracks.

Secondly, in teaching, the model should follow the principle of gradual progress. One can first observe the distribution of meridians as a whole, then gradually practice individual acupoints, and enhance understanding by combining theoretical explanations. During the demonstration, excessive bending or pulling of the model should be avoided to prevent damage to its internal structure.

Finally, after use, the surface of the model should be cleaned in a timely manner. You can wipe it with a clean soft cloth. Avoid using strong acid or solvent-based cleaning agents. Store the model in a dry and well-ventilated place, away from direct sunlight or high-temperature environments, to extend its service life.

By adhering to these precautions, the Fourteen Meridian Points model can not only enhance the intuitiveness of teaching but also effectively protect the model, ensuring its stable use in long-term training.

The children's thoracentesis training model is an important teaching aid for first aid and clinical skills training. It simulates the anatomical structure and tissue elasticity of children's breasts, providing learners with a safe and realistic practice environment. Its training process can generally be divided into the following steps:

First, the preparation stage. Check the overall condition of the model to ensure that the chest wall structure is intact and the puncture site is clearly marked. Prepare the necessary equipment, such as puncture needles, syringes, disinfectant cotton balls, etc., and keep the operating environment clean.

Secondly, positioning and disinfection. According to clinical requirements, trainees need to accurately locate the puncture point on the model (mostly in the intercostal space of the midaxillary line). Subsequently, a routine skin disinfection and towel spreading operation was simulated to cultivate a standardized sense of asepsis.

Third, puncture operation. The operator slowly inserts the needle at a predetermined Angle, and the touch will simulate the resistance and breakthrough sensation of the real chest wall. After entering the thoracic cavity, it can be confirmed whether the puncture was successful through suction or feedback devices.

Fourth, fluid aspiration or decompression training. According to different teaching objectives, the operation of pleural effusion extraction or pneumothorax decompression can be simulated to familiarize with the subsequent processing procedures.

Finally, conclude and organize. After the operation is completed, the puncture needle should be removed, the consumables properly disposed of, the model cleaned and stored to ensure its normal use in the next training.

Overall, the children's thoracentesis training model, through standardized process training, not only enhanced the trainees' operational skills but also strengthened their emergency response capabilities in clinical treatment.

The precautions for the adult tracheotomy care model mainly lie in two aspects: standardized operation and safe training. First of all, before using the model, it is necessary to check whether the tracheotomy site and related accessories are intact, keep the airway unobstructed, and avoid affecting the training effect due to component damage. During the operation, it should be strictly carried out in accordance with the clinical nursing procedures, such as changing the cannula, cleaning the incision, and suctioning care, etc. Ensure that the movements are gentle to avoid damaging the model, while maintaining consistency with the actual clinical operation.

During the nursing drill, the principle of asepsis should be noted. When performing sputum aspiration or changing the tracheal tube, it is necessary to simulate the process of wearing sterile gloves and using sterilized consumables to cultivate the correct aseptic concept among trainees. In addition, attention should be paid to the adjustment of airbag pressure and the stability of pipeline fixation to prevent model damage or training distortion due to improper operation.

After use, the model should be cleaned and maintained in a timely manner, especially the trachea cut and the pipe part, to keep it dry and clean, so as to extend its service life. At the same time, it should be properly stored to avoid deformation caused by high temperature, humidity or compression.

In conclusion, the adult tracheotomy care model plays a significant role in teaching. Only by paying attention to standardized operation and maintenance can its teaching value be better exerted and help trainees master standardized care skills.
