Abstract

This paper proposes the improvement of the process ofhealth recovery by using a medication dispenser. Wedesigned a pill dispenser which has different containeraccording to the different shapes of the tablets. Thedispenser revolves around Arduino microcontroller whichcontrols all the functions of the microcontroller. The timeto take the dosage is fed onto the reminder system, thisgives a buzzer at the right time. This system also has atalkback voice assist feature which acts as a voiceassistant. The count of the tablet and other vital signs likeheart beat and blood glucose level are read and stored tothe cloud storage. These values can be retrived by thedoctors or caretakers using a mobile app. In case ofemergency there is also an emergency button provided bythe system which sends the users location and alertmessage to the nearby hospital in order to get immediateassistance.

1 INTRODUCTION

Health recovery process can be improved by using helpful devicesthat make this process easier. A pills dispenser is such a usefuldevice. In general, elderly or chronically ill persons take manypills for their illnesses. It is very important for healing process orfor maintaining health to take medications on time, according todoctor’s prescription. If the patient doesn’t take medications inthe right dose and at the right time, the risks a deterioration of hishealth. A pill box (also known as pill container or pill organizer)is a container with many compartments for prescribed medication.A pill box compartment can hold several pills of different sizes.There are many types of pill dispensers (including rectangular,cylindrical or pen shapes) [1]. To make it easier to follow we splitthe system in following elements: Pill dispenser, Pill reminder,Health monitoring Recent research studies on the Internet ofThings and smart things domain shows how different elements ofhuman daily activities become increasingly dependent on eachother. Smart things are changing human life in the way thatnowadays without their applications life is becoming cumbersome.So making use of this in this medication concept will enhance thelife of patients, elders and virtually disabled people [2]

2 METHODOLOGY

In this project we are going to use Arduino as the microcontrollerwhich controls the overall process of this system. Healthmonitoring sensors such as heart beat sensor are used. Thesesensors are non-invasive in nature. The various health parametersmeasured by these sensors are sent to the micro-controller. Themicro-controller is already programmed with the threshold value,this reference value is compared with the measured values. If thevalues are below the threshold value, we will be able see thehealth parameters in a mobile application. Incase if it is beyond

the level the micro-controller will automatically trigger the GPSand GSM modules such that an alert message is sent to the caretaker so that immediate assistance can be provided at appropriatetime. The smart pill dispenser has an in-build clock to perform asa pill reminder. The keypad is interfaced with the pill box so thatmanual operation is also possible. Meanwhile the name of the pillwill be read out by the talk back option, even the healthparameters is also read out for the blind and elderly people. TheIR sensor is placed in such a way that it counts the number ofpills that is been dispensed. With the stored data in the cloud,the doctor will be able to assist the patient health. Evenself-health monitoring is possible in such case, which helps increating an awareness. A mobile app is designed specially, for realtime monitoring of heartbeat level. A cloud server is created or anexisting cloud like ”things speak” can be used in order to save thedata’s measured by the prototype in the cloud. This will be usefulfor the doctors and care taker to keep track of it. The main aim ofthis whole prototype and the app is to take the prescribed pills atthe right time without missing the dosage prescribed and to keeptrack of the health parameters regularly.

4 DESIGN AND

IMPLEMENTATION

The design of a pill dispensing system that is affordable to peoplein low incom countries, takes cognizance of first principles and theviability of local materials. The architecture of the pill dispensingsystem is shown in Figure 1. It is based on the following designprinciples: Simplicity, which enhances upgradability andmaintainability; Affordability, which is a crucial characteristic ofany system that has the potential of high utility in low-incomeenvironments; Flexibility, a characteristic that enables the systemto adapt to new user requirements through the addition of newfunctionalities and system characteristics.

5 USE CASE

6 PILL DISPENSER MODULE

We proposed a programmable pills dispenser. This device canrelease the medication at certain time intervals, This device offersan easily used service, which reminds through an buzzer. At asimple pressing of a button, the desired medication is obtained, atthe prescribed hours or prescribed time intervals. The pills arestored in their appropriate containers and the count of the pills

are obtained by the sensors which sends the tablet count value tothe cloud [2]. The motor driver IC (L298N) which is connected tothe Arduino microcontroller controls the rotation of the motors inthe pill box which regulates the dispensing of pills on keypress.Another important feature of the pill dispenser is that it has atalk back feature. This will be very much useful for the virtuallydisabled people.

7 PILL REMINDER MODULE

The Pill Reminder module is used to indicate the users to take thepills as per the time set in it. DS1307 is the frequently used realtime clock (RTC) IC for clock and calendar. The clock functionprovides seconds, minutes and hours while the calendar functionprovides day, date, month and year values. The increment buttonmust be pressed must be pressed to change the hours. As the clockis in 24 hour format, the hours will be incremented between 0 and23. Once the hours of the alarm is set, we must press the nextbutton to go to minutes tab. Again increment button is pressed tochange the minutes. Once the alarm time is entered, set button ispressed and the alarm is set.

8 HEALTH MONITORING

Health monitoring plays a vital role in providing the vitalinformation such as heart beat value etc.to the patients. In thisproject we have used the heartbeat sensor [5,6]. These two sensorsare connected to the Arduino microcontroller.

In case of pulse detector, a pulse oximeter sensor is placed onthe finger. The sensor id designed to provide a digital pulse rateof the user. While in the working condition the beat LED flashesin unison with the pulse rate. The digital output is connected tothe arduino board to give the number of Beats Per Second (BPS).The pulse sensor works on the principle of light modulation byblood flow through finger at each pulse. Global Positioning System

(GPS) is utilized to locate the patient [7, 8]. The latitude andlongitude estimation obtained is transmitted to the doctors phonealong with the current status of the patient using Global Systemfor Mobile (GSM) Communication [9].

9 EXPERIMENTAL RESULTS

The system was tested under various working conditions. Initiallythe pills are first loaded onto the desired containers. The reminderis also set manually or can be preprogrammed as per the dosageprescribed. The patient is provided with a keypad using whichthey can obtain the different type of tablet. As soon as the tabletgets dispensed a text to speech module will start to respond to thepatient and reads out the tablets name, this will act as a voiceassistant. Finally the pill count, heart beat value and glucose levelvalues are stored onto a cloud server. In case of emergency thesystem is provided with two buttons. The first button acts in sucha way that in case of any critical condition it is triggered and itwill send an alert message which contains the user’s location tothe nearby hospital to ensure immediate medical assistance. Thesecond button is used if there’s a shortage in tablet, this buttoncan be pressed manually to send a message to the pharmacy.
