Abstract
A respiratory mask includes a mask body with a perimeter. The mask has a use position wherein the mask body covers at least the mouth and nose and the perimeter is in contact with the face surrounding at least the mouth and nose. At least one ultrasonic sensor is supported on the mask body in detecting proximity to the perimeter. The ultrasonic sensor is operable to detect ultrasound. The ultrasonic sensor allows leakage around the perimeter of the mask body to be detected.
Claims17
A respiratory mask to be used on the face of a user such that the mask covers at least the mouth and nose of the user, the mask comprising:
- a mask body with a perimeter, the mask having a use position wherein the mask body covers at least the mouth and nose on a face of a user and the perimeter of the mask body is in contact with the face surrounding at least the mouth and nose;
- at least one ultrasonic sensor supported on the mask body in detecting proximity to the perimeter, the ultrasonic sensor operable to detect ultrasound;
- wherein the at least one ultrasonic sensor is disposed outboard away from the perimeter of the mask body;
- and
- wherein the ultrasonic sensor allows leakage around the perimeter of the mask body to be detected.
A respiratory mask to be used on the face of a user such that the mask covers at least the mouth and nose of the user, the mask comprising:
- a mask body having a central area and a perimeter, the mask having a use position wherein the mask body covers at least the mouth and nose on a face of a user and the perimeter of the mask body is in contact with the face surrounding at least the mouth and nose;
- a plurality of ultrasonic sensors each supported on the mask body, the ultrasonic sensors each being disposed adjacent the perimeter of the mask body and in detecting proximity to the perimeter, the ultrasonic sensors each operable to detect ultrasound;
- wherein each of the plurality of ultrasonic sensors are disposed radially outboard away from the perimeter of the mask body;
- and
- a microprocessor in electrical communication with each of the ultrasonic sensors, the microprocessor receiving a signal from each of the ultrasonic sensors and processing the signals to produce an output parameter corresponding to leakage at the perimeter of the mask body.
