Dr. Nguyen Phan Kien, the father of many biomedical products that have been commercialized to the market, said the automatic hand washing system was not a new device on the market. Even in Vietnam, this device is relatively popular, especially during the recent Covid 19 epidemic. However, most products sold in the market use non-fog technology or mechanical pressure technology with the same spraying method as sterilizing sprays.

With this technology, disinfectant water will be put into the palm of the hand, then, the user will have to rub their hands together, making the hand washing process takes a long time, not to mention, if the rubbing If not done properly, hand washing water will not guarantee covering hands. Therefore, hand washing does not guarantee the necessary cleanliness.

Another feature is that the amount of system solution is carefully designed to ensure that the amount required by the World Health Organization is from 3-5ml to enough to wash a hand. This helps the system ensure the amount of water is sprayed out fully (no excess, no shortage) for each wash.

The device is designed to be portable and the height can be changed, the device can be installed easily anywhere with the requirement of having a power source to supply the machine. The machine has a capacity of 2 liters of solution equivalent to nearly 700 handwashing.

About price, Dr. Nguyen Phan Kien said that the product cost 2.5 million VND / machine. Compared to similar machines in the market, this price is expensive.
