The world of allergy diagnosis and treatment is a high-tech one, and there’s nowhere you’ll see this better illustrated than on French company DBV-Technologies’ internet site.
Some of the most problematic allergies are connected to food. Peanut allergy has grabbed many headlines in recent years, probably because its effects can be fatal. However, in terms of impact on well-being and quality of life, cows’ milk protein allergy is very high up the list. Many children and babies are affected by this condition, which can produce distressing symptoms like vomiting, diarrhoea and skin rashes. DBV-Technologies’ answer to this allergy is explained in detail on http://www.dbv-technologies.com/en/products/allergy-treatments/viaskin-cows-milk/.
At the heart of this new solution is the Viaskin® patch and the electrospray technology pictured below that covers the patch evenly with electrically-charged droplets of protein (the allergens). The patch features an electrically-conductive backing specifically with the use of the electrospray in mind.
The patch also hydrates the skin, facilitating the penetration of the antigens into the skin and the Langerhans cells (antigen presenting cells). The antigens do not enter the bloodstream, thus reducing the risk of a severe or uncontrolled allergic reaction.
