Students develop IoT-based patient assistance system

Students at Chandigarh University in India are making technology work for paralytic and physically impaired patients by developing an IoT-based patient assistance system.
A visit to hospital and witnessing the plight of paralytic, cancer and physically impaired patients triggered the students of the mechatronics engineering branch of Chandigarh University to develop an IoT-based patient assistance system that can help the attendants better understand the requirements of the patients.
A team of fourth year engineers comprising Aman Gupta, Vivek Chauhan, Mayank Verma, Lalit Yadav and Ishan Nayak have come to the rescue of such patients who are not capable of speaking or using any signs to describe their needs to their attendants. Such patients include old age people with dementia, paralytic, physically disabled patients or last stage cancer patients.
The team has developed gesture based sensor technology that can be attached to the patients' hand to provide notifications to the attendants for certain requirements such as pain, wanting water or food, going to the toilet and so on.
The system has been designed with some pre-stored gestures (currently up to four) along with IoT board, gesture sensors, power circuits, wifi nodules and LCD screen speaker for emergencies. The system can also attach to voice-based online systems such as Google Assistant or Amazon Alexa.
The team is working on reducing the currently Rs5000 cost by developing a server-based model to which multiple devices can be attached.
"One of the main task of the IoT patient assistant system is to keep monitoring all the factors that a patient may need to be taken care for like number of times a patient called for assistance and how many times no one attended them, storing the important statistics like heartbeat level, BP level and blood sugar monitoring,” said Chauhan.
Another feature is that it comes integrated with an automatic water feeding system where water is slowly dripped into the patient’s mouth as soon it gets command from them, added Yadav.
"The idea came when we visited a hospital where I saw a paralytic patient who could not speak asking for water and there was no one to look after him," said Verma.
It took four to five months to develop the system and test it in a real-time situation. The students have filed a patent for the system and will try to enhance its capability.
Chandigarh University has established a technology business incubator at its campus where entrepreneurs and researchers are trained to help them set-up their own ventures. More than 100 start-ups have been established by the students of university and more than 400 patents have been filed by the research scholars and students.
Chandigarh University is an autonomous educational institution approved by UGC and is located near Chandigarh in the state of Punjab. It offers more than 109 undergraduate and post-graduate programmes in the fields of engineering, management, pharmacy, law, architecture, journalism, animation, hotel management, commerce and others.
