Another medically related entry to the James Dyson Award contest is the Pressure Alert for endotracheal tubes, a device intended to prevent the overinflation of the cuff balloon. Currently anesthesiologists and others have to use either their fingers to feel for pressure in an external balloon, or to use a specialized manometer that measures an internal pressure. The proposed system aims to take any guessing out of the process. If proven feasible, the same device, of course, can be used for trachs, double lumen endotracheal tubes, or even for endobronchial blockers.
The “Pressure Alert” is a unique adaptation for a medical device called an Endotracheal Tube, which is inserted into the patient’s airway allowing them to breathe during anaesthesia. The airway is sealed to prevent leaks by inflating a balloon called a “Cuff”. If the “Cuff” pressure is too high, it could bruise/split the trachea. Currently, a safe pressure is judged by feeling a “Pilot” balloon, but even seasoned anesthetists can misjudge this delicate procedure. “Pressure Alert” is the first device that gives a “pop-up” warning (patent pending), integrated into the pilot balloon to alert the user that pressure is too high, both at the start and during the operation. Additional USPs 1. The familiar mechanism helps user improve existing technique 2. The device offers instant recognition of potential danger 3. Requires no retro-fitting 4. Cost-effective production and lower environmental impact 5. Reduces patient recovery-times & risk of injury
