<p>A connector (1) connects an air-inflatable mattress (4) with alternately inflatable cells (11, 12) to a pump. Air-supply lines (13, 14) from the pump are attached to male body parts (2) of connector (1). Air-supply lines (15, 16) from mattress (4) connect to passages (17, 18) of female body parts (3) of the connector (1). When the male body parts (2) and the female body parts (3) are engaged, supply lines (13, 14) are in fluid communication with fluid lines (15, 16) via passages (17, 18) in the female body part (3). When the male body parts (2) are removed from the connector (1) to disconnect the air supply, one-way valves (7) seal the air-supply lines (13, 14) and expose a cross-connect port (8) interconnecting the female body part passages (17, 18). Thus cells (11, 12) are interconnected and the pressure is equalised throuthout the mattress (4). The invention provides a self-sealing automatic transport mode connection system as soon as the male body parts (2) are disengaged from the mattress (4), thus eliminating user error.</p> |
