Overview
This study designed a portable and easily accessible lung vibration device that is simple to use and can operate with both a battery system and a charging system for greater convenience. It helps enhance the effectiveness of mucus drainage, prevents complications, and reduces both the duration and cost of hospital treatment.
Description
Lung vibration device uses a motor as the power source to generate vibrations and has a shape similar to an iron. It is connected by an electrical cord in this section and can operate using either a battery system or a charging system. It features a vertically aligned handle perpendicular to the main body for a firm grip. The base of the device has a sponge head to absorb shock from the vibration during use, which is removable. The on/off switch is located at the end of the handle. This device uses 220-volt alternating current. The unit weighs approximately 1.1 kilograms and is made of strong and durable plastic.
