InsuPress is a smart and inexpensive wearable bolus insulin injector designed for developing countries like India. The drug delivery is completely mechanical, to keep the cost down — validation cost for electro-mechanical drug delivery is insanely high. It is a reusable device, by replacing the cartridge, and it has an AI-driven data logging and analytics system for detecting hyper- and hypoglycaemia. The device is part of a wider diabetes management system.
Why a wearable
The device was essentially designed to help working professionals manage their diabetes without any hassle or embarrassment. Usually they have to go to the washroom each time they want to inject insulin through an insulin pen. While using this device, they can just press the button to deliver the insulin. On each press, 2U of insulin is injected into their body.
Another disadvantage of using insulin pens is that patients have to keep puncturing themselves with a needle. With InsuPress the patient just needs to puncture themselves once a day, and the needle stays inside the body without any harm as it is a 32G needle — only 0.235 mm in diameter.
The device was also designed to work as a standalone injector, like an insulin pen, for when users are at home and would rather not wear it.
