The Air-X Syringe: using airway loss of resistance for safer cricothyroidotomies
Unmet Need
Between 13-20 million tracheal intubations are performed in the US each year, including surgical and emergency intubations. When the upper airway is obstructed, a needle cricothyroidotomy can be used to insert a catheter through the trachea. However, this lifesaving procedure risks puncturing surrounding tissue if physicians do not halt their needle after entering the airway. There is a need to reduce human error by ensuring that physicians can accurately gauge needle entry into the airways.
Technology
Duke inventors have developed a syringe that guides physicians during needle cricothyroidotomy. Using a pressure sensitive piston or spring, the syringe detects when the needle has entered the airway and visually alerts the physician. This tool is effective in healthcare settings and field settings where other intubation methods may not be available, such as combat zones.
Other Applications
This technology can be used in veterinary applications to preserve military service and civilian law enforcement animals.
Advantages
- Reduces human error and improves safety for needle cricothyroidotomy
