BED SYSTEM HAVING PROGRAMMABLE AIR PUMP WITH ELECTRICALLY INTERLOCKING CONNECTORS

摘要

A bed system is provided which limits the inflation time of each of a plurality of ventilating air mattresses with the system to a predetermined time. Each mattress includes a fitting with a spring biased pin for actuating a pump switch when the mattress fitting is properly mated with a pump adapter thereby facilitating inflation of said mattress. The pump is programmed to deactivate at the predetermined time, and to remain deactive until the pump switch is reset. The pin is positioned and constructed to be mechanically rendered inoperable in the process of resetting the switch thereby preventing each mattress fitting from actuating the pump switch a second time.
