The bleeding control arm model is a professional device used in emergency rescue and clinical skills training. It is mainly used to simulate different bleeding conditions after upper limb trauma, helping trainees master hemostasis methods and rescue procedures.

In conclusion, the principle of the standard acupuncture model is to transform the traditional meridian theory into visible, touchable and operable teaching tools through highly realistic and intuitive means. This not only makes up for the limitations of paper textbooks, but also enhances the scientificity and practicality of acupuncture teaching and clinical training.

The operation norms of the advanced infant comprehensive first aid training manikin are designed to help trainees master the first aid skills for newborns and infants, ensuring that the training is scientific, safe and effective. Before operation, it is necessary to check that the simulation maniac is in good condition as a whole, confirm that the airway is unobstructed, the power supply is sufficient and all physiological feedback functions are normal.

The suture practice module is not only applicable to the teaching of basic courses in medical colleges and universities, but also widely used in the training of surgical residents, skills assessment and preoperative practice. Through systematic simulation exercises, learners can transform their suturing skills into operational clinical abilities on the basis of theoretical learning, laying a solid foundation for future surgical operations and clinical practice.

After the training is completed, the mouth and chest area should be cleaned and necessary maintenance should be carried out to extend the service life of the model. Through systematic training in advanced adult airway infarction and CPR models, trainees can master the first aid operation procedures proficiently, improve their clinical emergency handling capabilities and the success rate of actual rescue.

The liver anatomy model is a simulation teaching aid used in medical education and clinical training. It is made based on the actual anatomical structure of the human liver and can visually display the shape characteristics, lobule conditions and important vascular systems of the liver. The liver, as the largest solid organ in the human body, undertakes multiple functions such as metabolism, detoxification, synthesis and storage. Its anatomical knowledge holds an extremely important position in medical learning.

The teaching value of this model lies in enhancing the standardized operation level and clinical diagnosis and treatment ability of medical staff. Through repeated training, trainees can master the key points of gynecological operations proficiently, cultivate clinical sensitivity, and reduce operational risks. Advanced gynecological training models not only play a significant role in teaching but also have positive implications in maternal and child health care and scientific research training, providing strong support for enhancing the health security level of women.

The pig body acupuncture model is a teaching aid specifically designed for the teaching and research of veterinary acupuncture. It is made based on the anatomical structure of the pig body and the meridian theory of traditional Chinese veterinary medicine. Models usually replicate the body shape features of pigs in proportion and mark the main meridian routes and commonly used acupoints on the body surface, such as the back-shu point and the key points of the limbs, to help learners quickly master the distribution pattern of acupoints.

The operation specification of the fistula and stoma care model aims to provide trainees with a standardized and normalized stoma care training process. This model is designed based on the anatomical structure of the human abdomen and stoma, with a realistic texture. It can simulate the shapes of colostomy, ileostomy and various fistulas, and is suitable for surgical care, rehabilitation care and self-care guidance and training for patients.

The acupuncture head training model is a teaching tool specifically designed for learning and training acupuncture operations on the head. It is made in proportion to a real person's head, with the surface precisely marked with the positions of commonly used meridians and acupoints on the head, such as Baihui, Taiyang, Fengchi, etc., and distinguished by color or number for easy recognition and memory.

The staged pressure ulcer care model is a highly realistic teaching device used for the prevention and care skills training of pressure ulcers.  It is designed according to the lesion characteristics of pressure ulcers at different stages and often covers the typical manifestations from stage I to stage IV, including skin redness, epidermal damage, exposure of dermis and subcutaneous tissue, necrosis and deep tissue damage, etc.  The surface of the model is made of simulated skin material, with a touch that is close to reality.  It can visually present the color, shape and texture changes of pressure sores at different stages, making it convenient for trainees to compare, learn and judge.

The significance and practical role of elbow joint models in clinical medicine are very extensive, especially in medical education, clinical diagnosis, treatment and patient communication, etc. Its application can effectively enhance the quality and efficiency of medical services and promote the development of medical technology. The following is a mid-term analysis of the specific role and clinical significance of the elbow joint model in clinical practice:
