| Question: Many people are struggling with drug abuse. More often, the overuse occurs in daily life. Doctors and guardians are hard to supervise patients to use the correct number of pills. There are several commercial items on the market now, but they all have some problems. Most of the existing smart pill boxes are not for drug abusers. This idea comes from the Health Maker Lab project 5. Solution Overview: We are going to design a smart cap for pill bottles. The smart cap has the following functions. FIrst, It has a dispenser system which can count exactly the number of pills needed for the patient each time to avoid overuse. Second, It has a security system to avoid any tampering with the cap or bottle. Lastly, it has a notification system which involves three parts. One is the LCD to display the number of pills. Another is the alarm to notify the user he can not take anymore. The last part is to notify the doctor or the guardian when the patient uses the drug and if the user has any misuse performances through phone apps. Video link provided by Health Maker Lab: https://healthmakerlab.medicine.illinois.edu/video_submissions/5e135a286e3da/5e135a286e3da_input_1.mp4 Subsystems: 1. Pill dispenser The pill dispenser will also work as the opening of the cap. It is the only way that pills can go out of the bottle. In other words, users can not open the cap/bottle in other ways. The pill dispenser will be a bottle mouth with a holder.( like the ones on the salt container) This structure makes sure that it will not let pills out when it is closed and it will not allow too many pills to be pulled out at one time. There will be a Photoelectric sensor placed inside the dispenser near the mouth. It will count when pills are taken out. 2. Security system Together with the reusable pill safe technology cartridge clips, we will add pressure sensors at the bottom edge of the caps to prevent any actions that are trying to open the bottle. For glass bottles, this can be replaced with glass break sensors which can determine whether the glass is broken or not from the breaking sound. 3. Notification system a. Communication Microcontrollers use network interfaces to interact with the sensors and to push the data to the IoT application for analysis. It will give signal to the alarms using bluetooth protocol when it detects the overuse from pill counting or tempering from pressure sensors. It will also be able to upload the data into the application using WiFi and let guardian/doctor to see it. b. LCD Display pill counts and time 4. Power system For medical use, the power consumption should be low and work as long as possible. Also, it needs to be precise since every mistake will cause big problems. Here we are thinking of using TI MSP430, which is a Low power consumption microcontroller. It is enough to use a 3V lithium battery. 5. Apps We will develop a simple phone application which can interact with PillSafe Smart Cap, so the provider/doctor can know it when it detects the overuse from pill counting or tempering from pressure sensors. 6. Improved App We will develop a more sophisticated application(one version for patient and one version for provider/doctor) if this class turns out to be an online class. We will add features like reminding the patient to take the pills though phone if he/she forgets to by not only connect the system to the provider/doctor’s phone but also connect it to the patient's phone. Criteria for Success All functions designed above are achieved successfully. Changes if make all online If this course goes all online, we will add more complex functionalities in the software part. We would add more data analysis functions and personal design to our App. People can react differently to the same drug based on their various absorptions to the medicine and their age variance. Based on the patient's age and his/her history of taking medicine, our app will be able to provide scientific data analysis and suggestions on his/her future drug using. |
