IoT in healthcare: Top areas used

One of the key success factors of a medical and any other startup is a correctly chosen niche. Here are some promising areas of IoT in the healthcare industry that could become your business ideas:

Let’s take a closer look at some examples of IoT in healthcare.

Personal health monitoring devices

Most medical IoT devices are used to monitor patients to know when they will need help. These technologies can be used for:

  • Tracking blood glucose levels. 1 in 10 people suffer from diabetes, making such smart medical devices vital for many people. The CGM (Continuous Glucose Monitor) constantly controls glucose indicators and sends the collected data to smartphones, so patients don’t need to go to a laboratory or buy a special glucometer. Besides, these mobile devices can share collected information with healthcare professionals and patients’ families.
  • Monitoring heart condition. Нeart rate checks do not protect people with health issues from rapid changes in their condition. Conventional continuous cardiac monitoring devices require patients to be constantly connected to wired machines. Conversely, medical devices for heart rate monitoring allow patients to move freely, while their heart health is kept constantly under control. According to Trail Runner, these devices are 90% accurate.
  • Managing mental health. IoT devices can also be useful for those who are prone to anxiety or depression. These devices monitor patients’ heart rate, blood pressure, and even eye movement. Besides, special medical apps regularly ask patients about their condition. Clients stay calm and notice deterioration in its early stages.
  • Producing smart contact lenses. Wearable devices powered with IoT technology will help people see better. They can also be integrated with other digital health services. For example, they allow customers to take pictures just by looking at the object. These technologies can turn human eyes into powerful tools for interacting with the world.
  • Hand washing notifications. Previously, such devices were not in-demand, but now more hospitals are implementing them. Wearable sensors detect the level of hand contamination and notify patients to wash them. Certainly, such devices cannot wash hands instead of their owners, but CleanLink experts argue that such technology can reduce the spread of infections by 60%. Thus, they can also lower healthcare costs.

These examples of IoT devices have beneficial consequences: healthy patients, better treatment, and safe life. With thorough idea development and competent execution, they are radically changing people’s lives.

Medical equipment

Keeping track of all equipment, especially in large clinics, is challenging. The lack of good monitoring systems can lead to sudden breakdowns, which can at best affect the company’s financial performance and, at worst, the health of patients. IoT sensors embedded in equipment lower these risks. They notify the hospital staff of malfunctions in a tomograph or an increase in temperature in a refrigerator with biomaterial. Healthcare providers are able to react quickly and fix problems with minimal harm, also improving patient care.

Room control

During the pandemic, disinfection solutions have been especially relevant. The Internet of Things allows medical devices to monitor the condition of rooms and, if necessary, disinfect them, freeing personnel from this task. Thus, hospitals and clinics maintain a healthy microclimate which is good for patient health. Such solutions can be used not only in a medical facility but also in other public places such as cafes, cinemas, shops, malls, etc.

Managing healthcare organizations

The rising automation makes lives easier. In medicine, it’s a way to remotely track medications, keep medical records, and monitor available medical equipment for procedures and research. Software applications can be useful to patients. They help navigate huge hospital complexes and find the needed wards or medical professionals. Organization management products can be useful across all patient care industries.

Virtual wards and hospitals 

To reduce the burden on medical personnel, virtual hospitals have been opened in many countries. For instance, doctors at RPA Hospital in Australia use pulse oximeters that measure blood pressure and oxygen saturation and armpit patches that measure temperature. Thanks to such devices, both parties are exposed to less risks to their health. Additionally, they can react to changes in time and take emergency treatment measures.

Examples of medical technology application

Many projects that entered the Internet of Things market on time have become in-demand all over the world. Here are some interesting startups to guide and inspire you.

MedAngel. Ambient temperature control sensors

Some medicines get spoiled at high temperatures. Artificial intelligence technology in medical field allows MedAngel IoT sensors to monitor temperature and environmental conditions in a healthcare facility and alert the user if they are near a critical point or if medications have already been spoiled. This project is essential for those who take heat-sensitive drugs, improving health conditions and simplifying the treatment process.

Medicsen. Automatic drug delivery system

Such health systems consist of implanted wireless IoT medical devices and external drug delivery devices. They monitor a person’s vital signs and regulate the amount of medication injected. Users have access to individual personalized data. Predicted glucose levels based on patient personal health information could help to avoid potential risks during the device operation.

Elfi-Tech. Self-test devices

A patient monitoring system with self-test options allows patients to check their blood, urine, etc. and monitors patients’ indicators. Hence, people do not have to waste time queuing at medical centers, especially if they have to control these indicators all the time. Test results are immediately available in the app connected to the tester. The device non-invasively measures skin blood flow, blood flow velocity, coagulation, vascular status, and relative cardiac output (RCO) in addition to pulse and movement.

Self Care Originals. Smart healthcare systems

Systems detect symptoms of an asthma attack, heart attack, or epilepsy before they start. They automatically notify owners and designated trustees to alert them of dangerous changes right after the detection. They work in conjunction with the app and web portal and help asthma patients set medication reminders, collect data, and manage treatment plans.

InPen. Smart injectors

Smart pens-injectors automatically record the time and size of the medication dose used. They immediately recommend the next dose. The devices interact with smartphone apps that store and share information to help patients calculate medication dosage and get analytic reports.

Benefits of IoT in healthcare

The use of IoT in healthcare has countless benefits. Here are the main ones:

  • Significant improvement of treatment outcomes. The reason for this is the high accuracy of the data collected by IoT devices. These devices allow medical workers to accurately monitor the conditions of patients and implement the necessary treatments.
  • Medical errors are minimized. Patient information can be quickly collected and sent to experienced doctors or to cloud platforms. AI-based algorithms can also help make decisions based on existing data.
  • Cost savings. With IoT in healthcare, non-critically ill patients will be able to stay at home, while IoT devices track and send important information to the healthcare facility. Consequently, patients will not have to stay in hospitals for too long, and doctors will be able to direct their efforts to the treatment of the severely ill.
  • High level of safety. This is especially important during the pandemic when it’s necessary to protect the sick as well as the medical staff. IoT devices allow medical personnel to monitor the condition of patients and medical facilities while minimizing contacts between them. For example, these devices can provide information about the cleanliness of the air and the regularity of room cleaning.
  • Future-oriented solutions. Initial investments in this area involve implementing IoT infrastructure, installing devices, and training employees to work with software systems. However, after creating an IoT ecosystem, medical workers can easily integrate new gadgets as they are developed. A smart hospital with IoT support will be years ahead of similar institutions equipped with standard solutions.
