Abstract

1530298 Mattresses GELMAN HAWKSLEY Ltd 11 Oct 1975 41733/75 Heading A4M [Aslo in Division F2] A mattress unit for medical use comprises a flexible synthetic resin envelope 1 comprising two superimposed layers united around their peripheries and along lines defining two serpentine ducts 2,3 with respective inlet ports 2A,3A and outlet ports 2B, 3B releasably connectible to a hose assembly 4 connected to a control unit 5 controlling temperature and flow of water through the ducts. The control unit 5 comprises a switch operated pump 6, a reservoir 8 containing a thermostatically controlled heater 7, a valve 12 and a pivoted lever 11 movable to and fro by a selectively operated drive motor 9. In one mode of operation the lever 11 is swung to and fro about its pivot 11B by means of the drive motor which rotates a drive plate 9A carrying a pin 9B which is engaged in, and reciprocates along the length of, a slot 11A in the lever 11. The free and 11C of the lever 11 is disposed externally of the non-ferrous body of the valve 12 and its movement effects cyclic displacement of a valvemember 12A in the form of a magnet or magnetizable material between positions in which it closes one or other of two outlet ports 22,23 of the valve 12. The valve ports 22,23 communicate with the mattress inlet ports 2A,2B so that the displacement of the valve-member 12A allows circulation of water alternately through the ducts 2,3 to inhibit formation of decubitus ulcers on the user. The valve 12 has a single inlet duct 21. In another mode of operation the motor 9 is switched off whereby a microswitch operated by a formation on the plate 9A causes the lever 11 to stop in a position in which the valve-member 12A stops in a mid-position to open both valve outlet ports 22,23 and permit flow of water simultaneously through both ducts 2,3.
