The forefront of medical technology has always been patient care for diabetes. This review highlights smart insulin delivery systems, linked and continuous glucose monitoring technologies, and other developments that support patients and healthcare professionals in managing blood sugar levels and making decisions related to diabetes treatment.
The cost of sharing diabetes data has decreased, and accessibility has improved thanks to advancements in computing and communication technology. Patients and doctors can now easily and automatically upload the data to the cloud, making it possible for everyone to access pertinent data in real-time. Since major device manufacturers like Abbott Laboratory, Dexcom Inc., and Medtronic have started sharing common formats (such as ambulatory glucose profiles) and data, diabetes-specific devices can now be linked to smartphones, establishing a strong platform for remote monitoring and management.
Minimally Invasive or Non-Invasive Glucose Monitoring
The sole means to monitor a patient's blood glucose and modify their insulin administration has always been through self-monitoring using capillary blood glucose meter. While continuous glucose monitoring (CGM) devices reduces the need for blood testing, patients still need to be pricked with a tiny needle. However, contemporary sensors (like the eversense from Senseonics) that are implanted under the skin of the arm or belly take blood sugar readings every few minutes. The outcomes are wirelessly transmitted to a pump, a smartphone, or another device. These gadgets are now more accurate, and they can now operate for up to six months instead of just 15 days.
A less intrusive way to measure blood glucose levels is with microneedles. For instance, scientists at the University of Tokyo have set up microneedles on an adhesive patch and paper sensor. The biofluid is drawn from the skin by capillary force and transferred to the sensor for detection. Skin patches (Abbott's FreeStyle Libre; sugarBEAT CGM from Nemaura Medical), nanotechnology-based gas sensors (AerBetic Inc.), or radio wave technology are examples of non-invasive linked sensors that measure glucose (Sense Glucose Earring).
Insulin Delivery: Smart Pens & Pumps
There is a competition to develop tech-enabled, more intelligent insulin delivery systems. Smart pens from Novo Nordisk are developed to automatically record the amount of insulin administered and offer the data needed to identify patterns and improve therapy for insulin pump users.
Eli Lilly & Company, a major competitor in the industry, has introduced a smart insulin pen with a dosage decision support app, Automated Insulin Delivery (AID), with its typical disk-shaped pump CGM, and a hybrid closed loop control algorithm. Bigfoot Biomedical has created smartpen caps that integrate data from continuous glucose monitors, instructions from healthcare providers, and suggested insulin doses for diabetics.
Additionally, many companies have created several sophisticated bolus calculators particularly for insulin pumps, which allow real-time adaptation of the prandial and basal doses by integrating several factors, such as the patient's unique phenotype's specific glycemia or insulin sensitivity. They employ AI algorithms that are self-learning and specially tailored to the patient's history of hyperglycemia fluctuations.
Market Forecast for Diabetes Care Devices According to Growth+ Reports (https://growthplusreports.com/,) the global diabetes care devices market was pegged at US$ 32,255.9 million in 2021 and is expected to witness a CAGR of 8.3% during the forecast period from 2022 to 2030. One of the main factors driving this rise in demand for diabetes care devices is the increasing population of diabetic patients in both developed and developing countries. The other trends aiding the expansion of the market are the developing economies of nations like China, India, and several Pacific Rim nations. Additionally, more efforts are being made by healthcare experts, business leaders, and insurance providers to create awareness among the patient community about effective diabetes treatment.
