A bottom cover (32) extends over the first and second hoses (20, 26) and a portion of the hose receiver (16) and a top cover (34) extends over the bottom cover (32) and at least partially conceals the latch (18). Fluid is configured to pass through the first and second hoses (20, 26) into the connector housing (12) in a substantially linear direction thereby minimizing noise and fluid loss of the connector assembly.

An apparatus includes a power converter to convert incoming alternating current (AC) mains power into a direct current (DC) voltage. A linear AC pump of the apparatus has an arm that reciprocates linearly back and forth to move a pair of diaphragms to pressurize air that is output from the linear AC pump. The apparatus also includes a DC motor driver having an H-bridge that receives the DC voltage from the power converter as an input and that generates a square wave as an output that is coupled to the linear AC pump to drive the arm back and forth. The pressurized air from the linear AC pump is used to inflate one or more bladders of an air mattress, for example.

The control unit (22, 84, 210) is configured to communicate the type of button press determined by the driver (20, 94, 230). The tag (12, 42, 44) also includes a transmitter (24, 74, 264) in communication with the control unit (22, 84, 210). At least one receiver (26) is configured to selectively communicate with the transmitter (24, 74, 264). A controller (28) is in communication with the at least one receiver (26). The controller (28) is configured to determine a location of the at least one tag (12, 42, 44) within a predefined area based on information from the at least one receiver (26), correlate the type of button press from the at least one tag (12, 42, 44) with a message (30), and generate a notification (32) to communicate the message (30).

A patient proning system (10) includes: a support apparatus (16) including a frame (14); a surface assembly (12) configured to be positioned on the frame (14) of the support apparatus (16), wherein the surface assembly (12) includes a pneumatic system (18) that includes bladders (20, 120, 122, 124, 126, 128, 130, 218, 236) and a pump (30) in fluid communication with the bladders (20, 120, 122, 124, 126, 128, 130, 218, 236), wherein the pump (30) is configured to adjust the bladders (20, 120, 122, 124, 126, 128, 130, 218, 236) between a deployed condition and a non-deployed condition; a controller (32) communicatively coupled to the pneumatic system (18), wherein the controller (32) is configured to: selectively control the pneumatic system (18) in a standard mode and a prone mode based on a patient support position, including adjusting the surface assembly (12) to define surface contours (330) when in the prone mode of operation; and generate at least one prone aid notification (36) that provides at least one of a reminder, instruction, alert, or information for assisting a caregiver in positioning a patient for the prone mode of operation; and a control panel (34) communicatively coupled to the controller (32), wherein the control panel (34) includes a user interface (38) configured to display a surface control screen (490), and wherein the surface control screen (490) includes a first icon (544) for activating the pneumatic system (18) to provide an alternating low pressure therapy of the surface assembly (12) in a standard mode of operation and a second icon (546) for activating the pneumatic system (18) to provide an adjusted alternating low pressure therapy of the surface assembly (12) in the prone mode of operation, and further wherein the prone aid notification (36) is configured to be communicated to the user interface (38).

A cable retention clip includes a base, a first leg extending from the base to a first end and movable between an open position and a closed position, and a second leg extending from the base to a second end. The base, the first leg, and the second leg define a channel for disposing a cable therein. The first end of the first leg is spaced from the second end of the second leg in the open position and defines an opening therebetween into the channel. The first leg engages the second leg in the closed position. A door at least partially extends across the opening when the first leg is disposed in the open position. The door is movable against a bias for inserting the cable through the opening into the channel and inhibiting removal of the cable from the channel through the opening.

Devices, and methods of implementing the devices, that can be used to prevent electrical disconnection in apparatus used in health care systems is provided. This disclosure relates to devices and methods that can increase the efficiency of patient support apparatus.
