“…Baslyman et al [ 22 ] used Wi-Fi triangulation and networked infrared hand sanitizer dispensers to track health care provider location and hand hygiene policy adherence in a quality improvement effort at The Ottawa Hospital. An Ultrasound/Wi-Fi hybrid RTLS system has found a niche in assisted living homes, replacing conventional call light systems, as each patient can toggle a button on their ultrasound tag, sharing their precise location with staff and notifying the care providers assigned to that area [ 23 ]. This system utilizes ultrasound hubs strategically placed around the medical facility to collect data from tagged staff, patients, and equipment and then Wi-Fi relays the information to a care management mobile app.…”

Background Lean methodology helps maximize value by reducing waste, first by defining what value and waste are in a system. In ophthalmology clinics, value is determined by the number of patients flowing through the clinic for a given time. We aimed to increase value using a lean-methodology guided policy change, then assessed its impact on clinic flow using an automated radiofrequency identification (RFID) based real-time locating system (RTLS). Methods A total of 6813 clinical visits occurred at a single academic institution’s outpatient glaucoma clinic between January 5, 2018 to July 3, 2018. Over that period, 1589 patients comprising 1972 (29%) of visits were enrolled, with 1031 clinical visits occurring before and 941 visits after a policy change. The original policy was to refract all patients that improved with pinhole testing. The policy change was not to refract patients with a visual acuity ≥20/30 unless a specific request was made by the patient. Pre-post analysis of an automated time-motion study was conducted for the data collected 3 months before and 3 months after the policy change occurred on March 30, 2018. Changes to process and wait times were summarized using descriptive statistics and fitted to linear mixed regression models adjusting for appointment type, clinic volume, and daily clinic trends. Results One thousand nine hundred twenty-three visits with 1588 patients were included in the analysis. Mean [SD] age was 65.9 [14.7] years and 892 [56.2%] were women. After the policy change, technician process time decreased by 2.9 min (p < 0.0001) while daily clinical patient volume increased from 51.9 ± 16.8 patients to 58.4 ± 17.4 patients (p < 0.038). No significant difference was found in total wait time (p = 0.18) or total visit time (p = 0.83). Conclusions Real-time locating systems are effective at capturing clinical flow data and assessing clinical practice change initiatives. The refraction policy change was associated with reduced technician process time and overall the clinic was able to care for 7 more patients per day without significantly increasing patient wait time.

“…An automatic alcohol hand sanitizer (AAHS) helps prevent the spread of infectious viruses in crowded areas such as schools, universities, and shopping malls. (4,5) Hand hygiene sanitizers (6,7) can be made contactless and automatic in different ways by using various sensors. In general, IR (4,8,9) and ultrasonic (10)(11)(12) sensors have been commonly used to produce low-cost sanitizer dispensers.…”

“…In general, IR (4,8,9) and ultrasonic (10)(11)(12) sensors have been commonly used to produce low-cost sanitizer dispensers. Some sanitizers use sensors (5,(13)(14)(15) to both detect the hands and monitor the level of alcohol, and devices can use IoT to monitor the levels of water and alcohol. A new light-dependent resistor (LDR) sensor (16) can be used to improve the performance of outdoor hand hygiene sanitizers on a sunny day.…”

Hygiene is necessary to maintain human health. Hygiene keeps the body clean and free from germs, preventing the spread of diseases, which has been especially important during the COVID-19 pandemic. For this reason, we designed automatic alcohol hand sanitizers (AAHSs): one with an IR sensor and one with an ultrasonic sensor. The sanitizers will help prevent germs from spreading via the hands of people because no part of each device need be touched during its use. The AAHS with the ultrasonic sensor has various advantages over that with the IR sensor: it is 32% cheaper to produce, easier to configure and maintain, has a higher average score for user satisfaction, is smaller and more portable, and can use rechargeable batteries. In addition, its low cost makes it more suitable for commercialization. It can also be installed both outdoors and indoors. In an outdoor test, it was demonstrated to operate flawlessly. This paper includes useful information on the components of the AAHSs with the two types of sensor and an evaluation of their performance using confusion matrices.

“…A sanitizer dispenser can be made touchless automatic in different ways since various types of sensors can be used to sense the proximity [8]. Generally, ultrasound sensors [9][10][11][12][13][14][15] and infrared sensors [16][17][18][19][20] are used to make a low-cost sanitizer dispenser, but they show poor performances in public places where there is a lot of noise. Some dispensers are based on infrared radiation (IR) sensors, but they show malfunctions especially on sunny days where sunlight intensity varies because of clouds or reflection from the ground.…”

Development of a Novel Design and Subsequent Fabrication of an Automated Touchless Hand Sanitizer Dispenser to Reduce the Spread of Contagious Diseases

Background: The use of a touchless automated hand sanitizer dispenser may play a key role to reduce contagious diseases. The key problem of the conventional ultrasonic and infra-red-based dispensers is their malfunctioning due to the interference of sunlight, vehicle sound, etc. when deployed in busy public places. To overcome such limitations, this study introduced a laser-based sensing device to dispense sanitizer in an automated touchless process. Method: The dispensing system is based on an Arduino circuit breadboard where an ATmega328p microcontroller was pre-installed. To sense the proximity, a light-dependent resistor (LDR) is used where the laser light is to be blocked after the placement of human hands, hence produced a sharp decrease in the LDR sensor value. Once the LDR sensor value exceeds the lower threshold, the pump is actuated by the microcontroller, and the sanitizer dispenses through the nozzle. Results and discussion: A novel design and subsequent fabrication of a low-cost, touchless, automated sanitizer dispenser to be used in public places, was demonstrated. The overall performance of the manufactured device was analyzed based on the cost and power consumption, and environmental factors by deploying it in busy public places as well as in indoor environment in major cities in Bangladesh, and found to be more efficient and cost-effective compared to other dispensers available in the market. A comprehensive discussion on this unique design compared to the conventional ultrasonic and infra-red based dispensers, is presented to show its suitability over the commercial ones. The guidelines of the World Health Organization are followed for the preparation of sanitizer liquid. A clear demonstration of the circuitry connections is presented herein, which facilitates the interested individual to manufacture a cost-effective dispenser device in a relatively short time and use it accordingly. Conclusion: This study reveals that the LDR-based automated hand sanitizer dispenser system is a novel concept, and it is cost-effective compared to the conventional ones. The presented device is expected to play a key role in contactless hand disinfection in public places, and reduce the spread of infectious diseases in society.
