When used with a soft mouth attachment, RoseCup can control the amount of liquid during meals. It needs to release the liquid by sucking the soft mouth, and only a small amount of it flows into the mouth each time to avoid continuous liquid outflow, effectively control the dosage of each dose, and reduce the risk of suffocation. Soft and ergonomic nozzle that fits the patient's palate and optimizes push force. The patient can suck before swallowing, and the nozzle is equipped with a valve to further regulate the fluid volume to prevent suffocation or inhalation of the lungs.
