Abstract: 1,171,311. Washing bed-pans. DENT & HELLYER Ltd. 14 March, 1967 [14 March, 1966], No. 11006/66. Heading A4N. A bed-pan washer comprises valve means forming part of fluid supplying means for controlling the supply of sterilising fluid to the interior of a hopper, means for sensing the temperature of the sterilising fluid supplied to the hopper via a valve means, a timing means controlling closing of the valve thus terminating the supply of sterilising fluid to the hopper a predetermined time after initiation of the timing means and means for initiating the timing means when the temperature of the sterilising fluid sensed by said sensing means attains a predetermined minimum value. The temperature-sensing means may be mounted inside the hopper or in intimate contact with, or inside the pipe. It may be remote from the means for initiating the timing means and may be arranged to control the initiating means via any suitable mechanical, electrical, pneumatic or hydraulic device. The temperature sensing means may be a temperature-sensitive element (e.g. a bimetallic element or bellows) of a thermostatic electric switch, the contacts of the switch serving as the initiating means for the timing means. The timing means may be a rotatable mechanical device adapted to be rotated at a substantially constant angular velocity when initiated e.g. a camshaft bearing a cam controlling the opening and closing of said valve means, the camshaft being driven by an electric motor. The prefessed sterilising fluid is steam at a temperature of at least 212‹ F. A hopper 2 has an outlet leading via a trap 3 to a sewer 4, a cover 5 with a bed-pan support 10 and a conduit 12 supplying washing liquid to the interior of the hopper and connected to a pump 13 driven by an electric motor 14. Conduit 15 connects pump 13 to the valves 16 and 17 mounted on casing 18. Valve 16 controls passage of hot water to conduit 15 from hot water tank 19 via conduit 20 and valve 17 controls passage of cold water to conduit 15 from cold water tank 21 via conduit 22. The tanks 19 and 21 are supplied from a water mains and water in tank 19 may be heated for example by an electric immersion heater 25 controlled by thermostatic switch 26. An electric motor 35 drives two cams 28 and 29 which control valves 16 and 17 and are fixed to a camshaft 30 which is rotatable and on which is mounted another cam 60 which controls a valve 61 in a steam supply pipe 62 for the hopper. A thermostatic switch 63 controls attainment of a predetermined temperature in pipe 62 and a microswitch 64 is arranged in parallel with switch 63.
