AI Technical Summary

Technical Problem

Existing emergency eyewash stations are prone to clogging, contamination, and corrosion in emergency situations, which can prevent timely and effective rinsing and pose potential eye health risks.

Method used

An eyewash station was designed, comprising a retractable nozzle, a water supply mechanism, and a shield. The nozzle is stored in a sealed cavity when not in use. The water supply mechanism stores sterile cleaning solution to prevent exposure to the outside environment and is independent of the public pipe network. The nozzle is designed to resemble the shape of a human eye and is made of silicone. It is equipped with a pulse pump to ensure the cleanliness and stability of the cleaning solution.

Benefits of technology

It effectively prevents nozzle contamination, reduces the risk of pipe blockage and corrosion, ensures the sterility of the cleaning solution and immediate water output, improves the safety and efficiency of emergency rinsing, and reduces secondary damage to the patient's eyes.

Abstract

This utility model discloses an eyewash device, comprising: a nozzle, which is a retractable nozzle; a water supply mechanism, the outlet of which is detachably connected to the nozzle, the water supply mechanism being used to store cleaning fluid and to deliver the cleaning fluid into the nozzle; and a shield, the shield being detachably connected to the water supply mechanism, with the nozzle in its retracted state stored in a sealed cavity formed between the shield and the water supply mechanism. This effectively prevents the nozzle from being directly exposed to the external environment, thus preventing the nozzle from being attacked by dust, impurities, and other pollutants, ensuring the cleanliness of the cleaning fluid, and thereby avoiding further damage to the patient's eye health.
