Large Volume Wearable Injectors: A breakthrough to simplify Chronic Disease Management
The last few years have witnessed a rising incidence of chronic illnesses across the globe. Long term clinical conditions, such as neurological disorders, cardiovascular disorders, chronic pain and oncological disorders, have been shown to impose a significant burden on the modern healthcare system and those who suffer from such diseases. It is reported that about 60% of all adults in the US are currently suffering from one of the aforementioned chronic conditions. Further, the total spending on such patients is estimated to be close to USD 3.5 trillion. Thanks to the geniuses around the world, large volume wearable injectors have been developed to offer a safe and convenient solution to patients by overcoming challenges associated with conventional injectors, such as volume limitations and viscous drug administration and frequent drug administration requirement. Conventional drug delivering methods may cause needle-stick injuries while drawing blood, administering intravenous drugs, disposing used needles, handling medical waste and performing a myriad of other routine procedures. Variants of large volume wearable injectors with disposable design and needle insertion and retraction systems can aid in significant reduction in such instances. Indeed, a win-win scenario for both patients and health care professionals!
Presently 30+ and 25+ large volume wearable injectors are marketed / being developed for the delivery of insulin and non-insulin drugs, respectively. Devices, such as Omnipod (Insulet), and SmartDose Electronic Wearable Injector (West Pharmaceutical Services), are some of the examples of approved large volume wearable injectors.
