Patent number: 8960195Abstract: A versatile, intubation-facilitating oxygen mask is provided including at least one diaphragm configured with a continuous, flexible, modifiable membrane from which an instrument-access port may be manually constructed, when and if needed. The novel oxygen mask preferably includes a multiple-inlet port having a standard oxygen tube connector and an interchangeable breathing-therapy device connector, a carbon dioxide sampling port, an exhaust port, and a nose clip. The mask can be worn as a standard oxygen mask during traditional oxygen therapy, yet quickly converted into an intubation mask. The clinician manually perforates the nasal and/or oral membranes of the one or more diaphragms to create a point and size of entry perfectly matched to the requirements for a variety of procedures that may be performed involving nasally or orally introduced scopes or probes—without disturbing the ongoing benefits of increased oxygen saturation and continuous monitoring of expired gases.Type: GrantFiled: February 4, 2013Date of Patent: February 24, 2015Inventor: Edward Lehman
