Description

Hand hygiene detection device, system and method

The present invention is related to a personal hygiene detection device; in particular, it refers to a hand hygiene detection device, which is used to manage whether the personal hand uses chemical substances to clean the hand hygiene detection system and method including the detection device.

Since the hand is the body with the most frequent communication among people, and many diseases are often spread through hand contact, hand hygiene has long been one of the key items of concern in many industries.

Taking the catering industry as an example, chefs who are responsible for cooking often need to grab ingredients and cut food with their hands. Therefore, the hands of chefs often come into contact with food. If the chef does not strictly clean his hands before cooking, it is easy to spread germs and cause harm to the health of consumers.

Take the educational environment as an example. Because teachers and students often do activities on campus, and many courses (such as outdoor activities, physical education, practical lessons, etc.) often have physical contact, if the teacher or student inadvertently touches the eyes, mouth, nose and other organs , It is easy for infectious bacteria to spread among people, causing group infection.

Taking the medical environment as an example, because medical staff interact with patients for a long time, if they do not keep their hands clean and hygienic, they are prone to self-infection or spread to other patients, and even large-scale nosocomial infections.

An average of 1.7 million patients in the United States each year are related to infections caused by medical care, causing huge losses to the country and society, as well as increasing morbidity and mortality in the population. According to the data, an average of 270 people die from health care-related infections in the United States every day, and the average hospital stay has increased from 7.4 days to 9.4 days, and the risk of morbidity is increased by 35%.

However, medical staff’s compliance with hand hygiene is generally considered to be less than 40%. According to this, the patient safety issue raised by the American Institute of Emergency Medicine (ECRI Institute) in 2018 directly refers to the “lack of hygiene concepts”. The hands of medical staff are recognized as the main reason for the spread of infections between doctors and diseases.

In summary, no matter what kind of industry or environment, as long as the hands are kept clean and hygienic, the spread of germs can be greatly reduced. In this way, not only can a relatively hygienic and safe living and working environment be created, but also unnecessary medical expenses can be reduced, thereby enhancing the people's psychological security.

In view of this, the purpose of the present invention is to provide a hand hygiene detection device, which can be used to remind the subject to clean their hands and detect whether the subject’s hands are cleaned with chemicals, so as to ensure that the subject can Always keep your hands clean and hygienic in the work or activity environment.
