A wearable device that facilitates record keeping, aids in the tracking of medications that have been distributed in a post-disaster context and allows the patient to take part in their treatment.

What is it?

We designed a wearable device that facilitates record keeping, especially in the tracking of medications that have been distributed in a post-disaster context and allows the patient to take part in their treatment. We want the device to be a wearable wristband with NFC communication technology that will store emergency medical information for individual patients. Medical professionals can access this information, load updated records onto the device, and set alerts to facilitate the patient’s care such as alerting them when to take medication.

How is it used?

The band is worn by the patient on the wrist (or ankle if needed), and the app is used by the medical professional. The patient’s individual information is stored on their wristband, the alert system uses their information to create a response based on prescriptions given, and the medical professional can access and store data quickly and easily. The NFC capable device will be placed near the wristband to sync the information to the device.

What technologies does it incorporate?

NFC communication, timer, alert system (LEDs and vibration motor), smart phone application.

How does it work?

The main technical considerations for this device will be allowing the medical professionals to keep track of information about the patients and their care without relying on much electricity or power. We believe that a good way to accomplish this would be through the use of near field communication (NFC) devices. This technology communicates information through close proximity, approximately 10 cm or less, which would be beneficial in crowded areas for there would be a reduced likelihood of unwanted interception or incoming information from another device. We used a transponder/microcontroller chip, that will simply store data for each patient which can be programmed with updated information by the nurses through a communicating device, such as an iPhone.

This concept also incorporates the use of an app that the nurses could use to communicate and access the patient information. The app will need to allow nurses and users to program the wearable for each patient: track how much medicine they are receiving, notify them of any existing conditions, and store other emergency medical information. This app should be able to easily connect to a larger network to compile and store large amounts of information. This could create a useful database for the professionals to show who was treated and how, as well as give insight into better treatment for disasters in the future.

The use of sensors and feedback for the patient are also being considered for this device. The device contains a patient alert system that will alert them when the nurse recommended that they take their medication. This alert would be through LEDs and a vibration motor that would indicate to the patient cues specific to their treatment.

Who uses it?

The first user of our device would be the victim of the natural disaster in need of medical attention who will wear the wristband. Our second user would be the medical personnel operating both the wearable device on the patient and the communicating application.

Why does it help?

We designed a wearable device that facilitates emergency record keeping, especially in the tracking of medications that have been distributed in a post-disaster context and allows the patient to take part in their treatment. This serves to make the aid effort more efficient, allows more patients to be treated, and let aid workers know what specific medications are in demand during a specific disaster situation. It could also provide much needed data on injuries sustained and medications prescribed in a post disaster situation to allow us to better prepare for future disasters. This device should be easily implemented in field hospitals, fit on patients of all shapes and sizes, directly pair medical records with a specific patient, remind the patient to take medications when necessary, and be easy to sanitize and reuse. It will have a phone application paired with it to be utilized by medical staff, and thus will need to be able to communicate with mobile devices, mostly likely through near field communication (NFC) technology. It also has a way to communicate with the patient (an LED and vibration motor), and has extremely low power consumption due to lack of power after natural disasters.
