Laryngeal masks are an effective way to ensure oxygen supply during surgery and are becoming standard-of-care. However, in 7.5% of the cases a laryngeal mask is used, an air leak develops during surgery. This causes an insufficient supply of air and an increased aspiration risk for the patient. In those cases, conversion to intubation may be necessary. Intubation is more invasive and causes additional physical stress and complications for patients, as well as prolongation of rotation time.



Anesthesiologist Khaled Rafiqpoor has developed the LarynxLock: a smart and effective device that prevents air leaks from occurring when using a laryngeal mask. By applying upwards pressure to the soft tissue of the bottom of the mouth, the internal anatomical shape is restored and leakage minimized. Patients are provided with sufficient air supply during the surgery and interruption of surgery or intubation is avoided.

Prevents air leaks and subsequent complications during surgery, lowers physical strain on patients and prevents prolongation of rotation time. A smart, cost-effective solution.
