Description

Hand hygiene detection device, system and method

The present invention relates to a detection device for personal hygiene; in particular, it refers to a hand hygiene detection device, a hand hygiene detection system and method for managing whether an individual's hands are cleaned with chemical substances including the detection device.

Hand hygiene has long been one of the key areas of concern for many industries, as the hands are the most frequently communicated limbs of the population, and many diseases are often transmitted through hand contact.

Taking the catering industry as an example, the chef responsible for cooking often needs to grab the ingredients and cut the food with his hands, so the chef's hands are often in contact with the food. If chefs do not clean their hands strictly before cooking, it is easy to spread germs and endanger the health of consumers.

Taking the educational environment as an example, since teachers and students often move on campus, many courses (such as outdoor activities, physical education, practical classes, etc.) often have physical contact. , it is easy to spread infectious bacteria in the population, resulting in cluster 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.

In the United States, there are an average of 1.7 million patients each year due to health care-related infections, causing huge losses to the country and society, while increasing the morbidity and mortality of the population. According to the data, an average of 270 people in the United States die every day from health care-related infections, and the average length of hospital stay has increased from 7.4 days to 9.4 days, and the risk of a 35% increase in morbidity.

However, the compliance of medical staff with hand hygiene is generally considered to be less than 40%. According to this, the patient safety issue raised by the American Emergency Medicine Research Institute (ECRI Institute) in 2018 directly pointed to the "lack of hygiene concept", among which The hands of health care workers are recognized as the leading cause of infection transmission between doctors and patients.

To sum up, no matter what industry or environment, as long as you keep your hands clean and hygienic, you can greatly reduce the spread of germs. 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 psychological sense of security of the masses.

In view of this, an object of the present invention is to provide a hand hygiene detection device, which can be used to remind a subject to clean his hands and detect whether the subject's hands are cleaned with chemical substances, so as to ensure that the subject can Always maintain hand hygiene in the work or activity environment.
