Personal gas supply delivery system
摘要:
A supply of gas such as oxygen is provided to a person in need of such gas supply. The delivery system includes an alarm to alert the recipient of the gas or another when and if the gas supply is disrupted. The alarm system preferably includes a reset and on-off switch that is recessed sufficiently to prevent accidental disabling of the alarm system.
