Overview

This page covers utility model patent CN 209003741 U (application no. 201820895099.X, filed 2018-06-11, granted 2019-06-21), owned by Dongguan Pengchi Purification Technology Co., Ltd.

The invention is a multi-station medical hand-washing station for hospital operating departments. It consists of a base cabinet, a multi-position hand-washing basin body, n sensor faucets (n ≥ 2), a full-length mirror, and a wave-shaped front edge formed by alternating yielding recesses and separating protrusions.

Each person stands in an individual yielding recess aligned with one faucet, while the raised protrusions separate adjacent stations and keep a defined distance between users — solving the collision and cross-contamination problems of ordinary multi-faucet scrub sinks.

Key Features

  • Cross-contamination prevention — physical separation eliminates body contact between surgeons scrubbing side by side
  • Privacy protection — separating protrusions shield adjacent users from one another
  • Automatic sensor faucets — touch-free operation, so clean hands never touch a switch
  • Built-in water heater — supplies warm water at every station
  • Sensor soap dispensers — one between every two adjacent faucets
  • Safety chamfers — 70–120 mm rounded edges on recesses and protrusions prevent injury
  • DuPont plastic basin body — seamless, durable, and easy to clean and disinfect
  • Flexible configurations — 2-station (FIG. 1) and 3-station (FIG. 2) versions; extendable to n stations
