Description

Hand clean ness test equipment for enhancing public Hygine}

The present invention relates to an inspection device for checking the state of cleanliness of hands to help change the hygiene culture, and more particularly, a device for washing and inspecting hands before a person eats an image that is enlarged 1 to several hundred times with a lens of a camera. The present invention relates to a device for checking a germ, such as a foreign substance, bacteria or a virus, on a hand by a TV or monitor.

In general, it is well known that learning and listening to parents or school when eating or eating should wash hands thoroughly.

However, not everyone knows how to wash their hands, but consciously invisible and habitually eats food, many diseases and foreign substances enter the body unknowingly and harm their health. The path to migrating is 70% of germs, which is higher than the incidence rate through the hops, and 51% of people wash their hands less than 5 times a day. It is sending germs into the body.

In addition, the hand is a direct contact with all surfaces. It is a mediator that transmits various foreign substances, bacteria, and viruses to the human body. It causes colds, food poisoning, epidemic conjunctivitis, and SARS. It is the easiest way to prevent infectious diseases by blocking the route of transmission to the human body through hands, and washing only hands can cause 70% of infectious diseases.

Accordingly, a number of techniques are known for hand washing apparatuses and hand cleaners, but hand cleaning state checking apparatuses are not known. Conventional hand-cleaning state checking technology is a device for observing germs or viruses by applying a gel used in a general institution or a laboratory, it is used only in a public health center or a hospital, and the range is narrow.

As described above, currently used hand washing inspection apparatus has the following disadvantages by applying a gel to the hand to observe the presence of bacteria in accordance with the change in color.

First, every time you eat food, you have to apply the gel to your hands to test. Second, it can be found only in special cases such as germs or viruses. Third, the range of use is limited and can be used only if you go to a public health center or a hospital. Fourth, in 2005, the Ministry of Health and Welfare did the national hand washing campaign called the 1830 movement, but many people did not know it. Anyone can be aware of hygiene, but it is difficult for each person to easily identify the invisible foreign objects in his or her hands. Fifth, it is expensive and hassle to purchase a gel steadily.

The present invention is to solve the above-mentioned problems, to provide a device for checking the cleanliness of the hand to check the cleanliness of the hand without using a separate gel or drugs.

The present invention attaches an optical lens to a general CCD camera, and the general public can also easily use the monitor to check his or her hand by comparing foreign substances on the hand with the image of the clean hand and the image on which the foreign substance is applied to the lamp or the voice. The goal is to change the hygiene culture and to feel the need for hand washing.
