Control System For Hospital Bed Mattress
First Claim
1. A mattress system comprisinga mattress having at least one inflatable bladder, anda control unit comprising a main housing, a source of pneumatic pressure carried by the main housing and operable to inflate the at least one inflatable bladder, and a plurality of user interface modules that are coupleable to the main housing, each user interface module being programmed to control inflation of the at least one air bladder differently in at least one operational mode of each of the plurality of user interface modules.

Abstract
A mattress system includes a mattress, a control unit spaced from the mattress, and a connector assembly that pneumatically and electrically interconnects the control unit with the mattress. The control unit has a main housing and a plurality of user interface modules that are selectively coupleable to the control unit and that are programmed differently to provide different modes of operation for the mattress system. A pressure sensor inside the mattress detects the presence or absence of a person on the mattress. The mattress system has a bed exit alarm system that, when armed, provides a bed exit alarm if the pressure sensor in the mattress detects that a patient has exited the mattress. The connector assembly includes a dual mode connector having both electrical and pneumatic couplers and a dual lumen hose assembly that extends from the dual mode connector to the mattress.

23. A mattress system comprising
a mattress including at least one inflatable bladder and a pressure sensor situated within an interior region of the mattress, and a control unit spaced from the mattress and having circuitry that receives a signal from the mattress which is indicative of a pressure sensed by the pressure sensor, the circuitry using the signal to establish at least one target pressure to which the at least one inflatable bladder is controlled and the circuitry also using the signal to determine whether to activate a bed exit alarm.

31. A mattress system comprising
a mattress having at least one inflatable bladder, at least one electrical component situated within an interior region of the mattress, a first pneumatic port in communication with the at least one inflatable bladder, and a first electrical connector in communication with the at least one electrical component, a control unit spaced from the mattress and comprising a main housing, a source of pneumatic pressure carried by the main housing and operable to inflate the at least one inflatable bladder, and circuitry programmed to control the manner in which the at least one inflatable bladder is inflated, the circuitry including a second electrical connector, the control unit including a second pneumatic port in communication with the source of pneumatic pressure, and a connector assembly to pneumatically connect the first pneumatic port with the second pneumatic port and to electrically connect the first electrical connector with the second electrical connector, the connector assembly including a pneumatic line, at least one electrical line, and a dual mode plug configured to permit connection of the pneumatic line with the second pneumatic connector substantially simultaneously with connection of the at least one electrical line with the second electrical connector.

42. A mattress system comprising
a mattress having at least one person support element, a pressure sensor situated within an interior region of the mattress, the pressure sensor being situated beneath the at least one person support element and comprising an enclosure containing a liquid, and circuitry that receives a signal from the pressure sensor and that determines, based on the signal, whether a bed exit condition has been detected.
