1. In the field of medical and health equipment, as an important device for assisting the rehabilitation of respiratory system diseases and daily respiratory function exercises, the innovation of the manufacturing process of the respiratory trainer directly affects product performance and user experience. In recent years, ultrasonic welding technology has gradually become a key process in the manufacturing of respiratory trainers due to its unique advantages, bringing new changes to this field.

The Principle and Advantages of Ultrasonic Welding

2. Respiratory trainers are usually composed of various components made of different materials, such as ABS plastic for the shell and medical - grade silicone for the internal pipes. Ultrasonic welding can well meet the welding needs of these different materials. By adjusting the welding parameters, reliable connections between different materials can be achieved, ensuring the overall performance of the product. For example, when connecting the plastic shell of the respiratory trainer to the silicone hose, ultrasonic welding technology can make the two closely combined. Under certain pressure and tension, the connection still remains stable without any phenomenon of falling off or air leakage.

Practical Application Cases and Effect Verification

3. A well - known medical device company adopted ultrasonic welding technology when developing a new type of respiratory trainer. After a large number of clinical trials and user feedback, the product achieved excellent results in terms of performance and user satisfaction. In clinical tests, the training effect of patients using this trainer for respiratory rehabilitation training was 30% higher than that of trainers manufactured by traditional processes. User feedback also showed that the durability and ease of use of the product were greatly improved, and the after - sales repair rate due to product quality problems was significantly reduced.
