Features: The world's first Bluetooth-connected "Oximeter" is convenient for observing the patient's physiological indicators during treatment and provides an early warning function;
Equipped with SD card function, it can store 10 years of work information, which is convenient for diagnosis management and scientific research work;
The ergonomic sputum vest design improves patient comfort.

The high-frequency chest wall oscillation sputum expelling meter consists of a pneumatic pulse generator, an air hose, an inflatable vest and an emergency stop switch. The pneumatic pulse generator inflates and deflates the vest at high speed through two air guiding hoses connected to the inflatable vest (or chest strap). When the frequency reaches a certain height, the chest cavity under the vest will oscillate, similar to Slight coughing action. The high-frequency oscillating chest wall simulates the chest wall oscillating action caused by cough, which relaxes and liquefies mucus and metabolites on the surface of the mucous membrane of the expiratory tract, making it smaller and looser and falling off. When the sputum moves from the bronchus to the main trachea, it can be artificially sucked out of the body to achieve a therapeutic effect.
