Abstract: The present invention connects to tubing through which gas flows to a patient. An alert notifies monitoring personnel that oxygen flow to the patient has been interrupted, because the tubing has been disconnected. The invention comprises an adapter that is connected to a gas or oxygen source and a nipple over which the tubing fits and through which oxygen flows to the patient. When the tubing becomes disconnected from the nipple, the oxygen flow actuates an alert. The invention includes a fixed arm, a swing arm, and a spring. When the tubing becomes disconnected, the swing arm pivots and causes a switch actuator to engage a switch that sends a signal to an alert. The alert can be audible or visual.

Abstract: The present technology relates to respirator devices including source control features. In some embodiments, a source control mask device can include a shield that substantially covers the mouth and nose of a user and a mechanism that can actively extract air as it is exhaled by the user. The extracted exhaled air can then be sanitized before the mask device discharges it into the atmosphere. The mask device may selectively form a seal to the user's face dependent on air flow conditions.
