US-F100 dispersive ultrasonic rock salt aerosol therapeutic apparatus is a portable and movable salt therapy equipment independently developed by Kuancheng Technology. Through ultrasonic atomization and high-temperature evaporation process, the equipment generates dry salt aerosol particles no more than 5 microns, forming a highly dispersed salt therapy environment in a relatively closed space. After ultrasonic atomization, the salt particle size is more stable and the concentration control is more accurate, so as to prevent, improve and treat respiratory diseases.

   Salt aerosol therapy, also known as dry salt aerosol therapy. Salt aerosol refers to a medium state of sodium chloride with very small particle size in the air. Generally, the particle size can vary from 1-5 microns. Dry salt aerosol is dry salt aerosol, which is a very effective non drug component for respiratory disease prevention and treatment. It is called 'salt therapy' to make patients inhale dry salt aerosol particles of a certain concentration to achieve curative effect by simulating the natural salt mine cave environment and internal microclimate conditions.

   Salt aerosol therapy is not a new concept. It has been studied, developed and applied for more than 100 years internationally. It originated in the World War II. The residents of Antipatu, Germany, have been using the natural Klutt Karst cave as an air raid shelter. Dr. Carl Herman was surprised to find that the health of asthma patients who stayed in the cave for a long time has been greatly improved. After World War II, European countries used the natural salt mine cave environment and internal microclimate to establish natural cave hospitals or salt therapy medical stations.

   In 1995, China began to introduce salt aerosol therapy. It has successively built salt therapy clinics in hospitals and convalescent institutions in more than ten provinces and cities, including Harbin, Hunan, Gansu, Henan, Shandong, Chongqing, Fujian, and applied salt aerosol therapy to the clinical treatment of asthma, rhinitis, chronic obstructive pulmonary disease, pneumoconiosis, silicosis and other occupational diseases. A large number of clinical studies at home and abroad have confirmed that salt aerosol therapy plays a very active role in the treatment of respiratory diseases.

   The main effect factor of salt aerosol therapy is dry salt aerosol particles with high dispersion, whose particle size is about 1-5 microns. The physical and chemical properties of dry salt aerosol determine that it is easier to attach to the respiratory tract and play a role.

   (1) Enhance clearance and promote alveolar mucus excretion: salt aerosols increase serous secretion, inhibit mucus secretion, supplement ionic components in mucus, regulate osmotic pressure between mucus and respiratory epithelial cells, reduce water loss in mucus, increase its hydration, and then restore normal rheology of mucus, improve ciliary motility, and protect cilia from bacterial toxins.

   (2) Anti inflammation, bacteriostasis and edema relief: salt aerosols increase the concentration of sodium ions in the living environment of bacteria, increase the osmotic pressure of solution, leading to dehydration and death of bacteria, so as to achieve the purpose of sterilization, significantly enhance humoral immunity, stimulate antibacterial and fungal mechanisms, and reduce inflammation related cell damage; At the same time, using the hypertonic principle, when the airway wall is edematous, the salt aerosol supplements the ionic component of the mucus blanket, increases the osmotic pressure gradient of the slurry layer, and makes the water flow from the airway wall to the lumen, thus playing the role of eliminating edema.

   (3) Enhance immunity and resistance: activate the innate immunity of lung tissue, enhance the activity of pulmonary macrophages, and regulate the immune function of the body.

   US-F100 dispersive ultrasonic rock salt aerosol therapeutic apparatus is applicable to department wards, treatment rooms, ultrasonic rock salt aerosol treatment rooms, etc. In a relatively closed space, it can be used by multiple people at the same time.

   In 2022, Research Progress of Salt Aerosol Therapy for Respiratory Rehabilitation proposed that clearing airway secretions is one of the important contents of respiratory rehabilitation, and effectively clearing secretions in the deep airway and minimizing discomfort of patients has always been a problem difficult to take into account clinically. Common airway clearance schemes include aerosol inhalation of expectorants, body position drainage, vibration expectorants and aspiration through the airway, Most of them have limited effect on the secretion of deep bronchioles, and bring pain to patients at the same time. Salt aerosol therapy can promote deep sputum excretion without obvious discomfort, and it is safe, convenient and easy to adhere to, and easy to promote.

   Professor Li Jian'an, International Academician of the National Academy of Medicine of the United States and Director of the Rehabilitation Medical Center of the First Affiliated Hospital of Nanjing Medical University, mentioned the salt aerosol therapy in 'The Extension of the Vision of Respiratory Rehabilitation'. It is pointed out that the salt aerosol means that the particle diameter is less than 5 μ M of sodium chloride aerosol, which can fall into the bronchioles with a diameter less than 1 μ M can reach the alveolar directly, increase the osmotic pressure of airway mucus, dilute sputum, and promote sputum excretion; It also helps to reduce congestion and edema of airway mucosa, and has local bactericidal and bacteriostatic effects. The role of salt aerosol therapy has been preliminarily recognized internationally and included in relevant clinical guidelines.
