Smart Bolo
The Smart Bolo came to VehiCLE as an alpha prototype. The device had some capability, but was not fully function. The Smart Bolo is a device that can detect if a nasal cannula is being worn correctly, and will alert the user or cut the flow of oxygen through the cannula if it is being worn incorrectly. The VehiCLE team pursued two solutions to this problem. Both solutions encorporate the same hub, which VehiCLE was able to greatly reduce the size and weight of, and sound an alarm with the cannula is being worn incorrectlyThe first solution involves 2 flex sensors that are worn around either ear, which connect to the cannula and are wired back to the hub of the smart bolo. If the flex sensors angle is changed out of the normal wearing range, the alarm will sound.
The second iteration involves copper contacts on the nosepiece. Using the copper contacts, the device can detect if the nosepiece is inside of the individual's nose. If the device becomes disloged, the alarm sounds.
Both solutions will be tested, and should help prevent improper use of home oxygen.
