Ultra-violet water steriliser and soap dispenser - operated by proximity probes

摘要

Ultra-violet light water steriliser comprises an electric valve controlling the distribution of the sterilised water and possibly another electric valve controlling the distribution of a sterilising liq. soap. The electric valves are controlled by a proximity probe which emits a signal each time the surgeon or other user places his hand opposite the probe at a certain distance. The frame houses the various components mounted on the plate, which is fixed to the wall over the usual sink. Water enters at through a reducing valve and passes through the treatment chamber contg. the germicidal ultra-violet lamp. A pipe conveys the water to the electric valve, with its relay, and to the distribution pipe and spout. The sterilised liq. soap from the jar is connected by pipe to the electric valve which delivers the soap to the nozzle. The pipes are sterilised through the pipe and the T joint. The surgeon has no need to touch any part of the appts. when he required sterilised water or liq. soap; he therefore runs no risk of soiling either his hands or his overall.
