Professional-grade medical device that assists in swallowing food
RS STIM
RS-STIM is the world's first medical device developed to enable patients with swallowing difficulties to swallow food immediately. It provides superior rehabilitation therapy compared to conventional devices due to its simultaneous swallowing exercise. Additionally, it prevents food from being aspirated into the airway, making it suitable for future home use.

Restoration of hyoid bone movement
When electrical stimulation is applied by RS-STIM, immediate restoration of hyoid bone movement to its normal trajectory can be observed, enabling clinical assessment of disability improvement, thus overcoming limitations of conventional products
Rehabilitation
RS-STIM shows significant improvements in VDS, FOIS, PAS before and after use compared to conventional 2-channel medical devices.
4-channel electrical stimulation
RS-STIM utilizes 4 channels (C1, C2, C3, C4) to deliver sequentially patterned electrical stimulation, ensuring proper functioning of the patient's swallowing muscles and enabling immediate food consumption.

Patients with weak swallowing muscles
If the swallowing muscles are weak, you cannot swallow food immediately.
Using RS-STIM, it sequentially contracts the swallowing muscles strongly, allowing food to move down the esophagus quickly and forcefully.
Patients who aspirate food into the airway during swallowing
Patients with severe dysphagia symptoms can experience respiratory distress when food is aspirated into the airway during swallowing.
Using RS-STIM, it strongly and sequentially contracts the swallowing muscles to prevent being aspirated into the airway.
