, Description:BACKGROUND
Field of the invention
[001] Embodiments of the present invention generally relate to a hand sanitization system and particularly to a smart multi-metric hand sanitization system and method thereof.
Description of Related Art
[002] A hand sanitizer is an agent that destroys or inhibits an activity of microorganisms that cause infectious diseases. The hand sanitizer can be a liquid, gel, or foam generally used to kill many viruses/bacteria/microorganisms present on hands. In most settings, handwash with soap and water is generally preferred. Shifting consumer preference towards convenient hygiene products is expected to drive a market. In a present scenario of a pandemic outbreak, a best way to prevent oneself from being infected is by ensuring a complete hygiene. The hand sanitizer is rubbed all over the hands, ensuring to cover entire hands including fingers, palms, and back of the hands.
[003] At public places such as companies, institutes, schools, shopping malls, railway stations, airports, and alike, a hand sanitization is usually done at an entrance of premises. In a current time of COVID-19 Pandemic, it became essential to keep a track of temperature along with the hand sanitization of every visitor on the premises. Temperature scanning along with the hand sanitization is usually done manually by a dedicated person at the entrance. For places such as shopping malls, railway stations, and airports, manual scanning of the temperature along with hand sanitization ends up wasting a time of the visitors. Many a times, the visitors have to form a queue for getting their hands sanitized and end up not following a social distancing protocol. The visitors in the queue becomes more prone to infectious diseases if the social distancing protocol is not being followed properly. Furthermore, the dedicated person who is assigned to take the temperature along with the hand sanitization of the visitors is more vulnerable to infectious diseases.
[004] There is thus a need for an improved and advanced multi-metric hand sanitization system that can administer limitations faced by the conventional systems.

[0060] FIG. 3 depicts a flowchart of a method 300 for automatically sanitizing the hands and monitoring the health parameters of the user by using the system 100, according to an embodiment of the present invention.
[0061] At step 302, the system 100 may receive the sensed distance between the user and the nozzle 120 of the sanitizer dispenser 106 from the infrared sensor 108.
[0062] At step 304, the system 100 may receive the sensed temperature of the user from the infrared temperature sensor 110.
[0063] At step 306, the system 100 may receive the oxygen saturation level and the heart rate of the user from the pulse oximeter sensor 112.
[0064] At step 308, the system 100 may compare the received distance between the user and the nozzle 120 of the sanitizer dispenser 106 with the pre-defined distance stored in the memory 116. If the distance between the user and the nozzle 120 of the sanitizer dispenser 106 is more than the pre-defined distance, then the method 300 may return to the step 302, else the method 300 may proceed to a step 310.
[0065] At the step 310, the system 100 may enable the sanitizer dispenser 106 to pump the pre-defined quantity of the sanitizing solution through the nozzle 120 of the sanitizer dispenser 106 onto the hands of the user.
[0066] At step 312, the system 100 may compare the sensed temperature with the pre-defined temperature. The method 300 may proceed to a step 316, when the sensed temperature is greater than the pre-defined temperature. Otherwise, the method 300 may return to the step 304.
[0067] At step 314, the system 100 may compare the measured oxygen saturation level and the heart rate of the user with the pre-set oxygen saturation level and the pre-set heart rate respectively. The method 300 may proceed to the step 316, when at least one of, the measured oxygen saturation level and/or the heart rate is greater than the pre-set oxygen saturation level and/or the pre-set heart rate respectively. Otherwise, the method 300 may return to the step 306.
[0068] At the step 316, the system 100 may display the message indicating the abnormality in a health of the user when at least one of, the sensed temperature, the measured oxygen saturation level, or the measured heart rate deviates from the respective pre-defined temperature, the pre-set oxygen saturation level, or the pre-set heart rate.
