Ventilation Face Mask

Facemasks are used in anesthesia, emergency medicine and resuscitation as part of positive pressure mask ventilation, which allows the forceful, active administration of oxygen or anesthetic gasses from a source to a non-breathing patient. In the ventilation process, the facemask is a device through which these gasses are administered to a patient.

When ventilating, the attending physician or emergency medical technician uses a bag-mask device, holds the facemask over a patient’s mouth and nose with the left hand and squeezes the bag (develops positive pressure air flow) with the right hand.

There are well-known problems associated with the use of existing facemask designs. Ventilation with a bag-mask is a complex technique that requires considerable skill and practice. To achieve a good facemask seal requires applying two simultaneous forces in opposite directions with one hand, using a grip in which the fingers are forced to assume a "claw-like" posture.

Positive pressure mask ventilation is not always successful. The quality of the seal between the mask and the face can be affected by the patient's facial bone structure, facial hair or other factors. Maintaining this seal is critical and often requires increased pressure applied to the face. It is well documented in the literature that maintaining this grip is uncomfortable, tiring, and painful, especially when increased force is necessary to obtain and maintain a seal.

Our design is a novel improvement to the conventional facemasks, which provides for an easier and more reliable seal, as well as ergonomic benefits. The mask would have the same form factor as conventional facemasks, and will be fully compatible with existing systems.
