Portable eyewash mask for lab safety

Eyewash mask designed with the aim of increasing safety in the laboratory by allowing each worker to have a portable pressurized water eye cleaning device nerby in case of an accident. 

The function of this prototype also aims to reduce the action time to clean the eyes, eliminating the time needed to find the fixed eye washer in the laboratory, thus reducing the possible damage to the worker's eyes due to contact with dangerous substances.

The pressurized water comes from a simple gardening pressure water sprayer, modified to fit very simple 6 mm clear tubing which connects the sprayer outlet to both mask nozzles.

You need to print:

1x Main_Chassis
1x Forehead_Support
2x Sprayer_Adapter
2x Nozzle
2x Retaining_Clip
2x Eye_Cover (Not necessary for operation, just looks cool :))

Printed in PLA, 0.4mm nozzle, 0.2mm layer height and supports.

Main chassis and forehead support piece connect by means of 2 DIN 312 M4 bolts and nylon locking nuts.
 

The mask works by putting it against the persons forehead and the nose adapter. Then press the sprayer actuator and presurized water will spray to the persons eyes cleaning them from debries or toxic substances. 

By pumping it around 20 times before the lab technician starts working, and having it within reach, it will give you about 30 seconds of continuous presurized water until it looses preassure. At that moment the person can pump it again and continue rinsing the eyes.
