Breathing apparatus with one or more safety sensors
View Patent ↗A breathing apparatus having one or more safety sensors that monitor the breathing gas supplied to a ventilation interface for contaminants. Upon detection of a threshold value of a contaminant, the apparatus activates one of more alarms, such as strobe lights, horns and/or piezo buzzers, to waken the user to the dangerous condition. The alarm may also comprise a notification system to first responders.
1. A breathing apparatus comprising:
a compressor having an inflow of ambient air and an outflow;
a ventilation interface;
a conduit in fluid communication with the outflow of the compressor and the ventilation interface;
at least one sensor in fluid communication with the outflow of the compressor capable of measuring at least one combustion generated contaminant within the ambient air-having an output;
at least one alarm connected to the output of the at least one sensor; and
a filter within the conduit downstream from the at least one sensor.
2. The apparatus of claim 1 wherein the output is determined based on a threshold value of the at least one combustion generated contaminant.
3. The apparatus of claim 1 wherein the at least one sensor is a carbon monoxide detector.
4. The apparatus of claim 1 wherein the sensor is a photoelectric sensor.
5. The apparatus of claim 1 wherein the sensor is an ion detector.
6. The apparatus of claim 1 wherein the at least one alarm is a strobe light.
7. The apparatus of claim 1 wherein the at least one alarm is a horn.
8. The apparatus of claim 1 wherein the at least one alarm is a piezo buzzer at least partially within the conduit.
9. The apparatus of claim 1 further comprises a third-party notification system connected to an alarm.
10. The apparatus of claim 2 further comprising an indicator light having an input connected to the output of the at least one sensor.
11. The apparatus of claim 1 wherein the at least one alarm generates a vibration through the conduit.
12. The apparatus of claim 1 wherein the at least one alarm modulates the air pressure in the conduit.
