Abstract:
A dual activated pneumatic actuator system for a patient call system includes a dual function hand held actuator for a pneumatic patient call system and having first and second air pressure domes; a pneumatically actuated switching device including two cylinders, contact pins and C-clips connected to the contact pins; and an air conduit system connecting the dual function hand held actuator to the pneumatically actuated switching device. When a first air pressure dome is depressed pressurized air forces a cylinder against its respective pin and C-clip to create a first circuit whereby an electrical signal is sent to an alarm system in the nurse station and when the second air pressure dome is depressed pressurized air forces the other cylinder against its respective pin and C-clip to create a second circuit whereby an electrical signal is sent to an electronic device, for example television or radio.
