A new injection device aims to reduce the fear and pain of injecting modern medicines in the home - by incorporating warming technology that quickly and reliably heats drugs to body temperature. Its cutting-edge design also makes it easy to use - transforming the patient experience.
Rheumatoid arthritis, psoriasis and a host of other conditions affecting millions of people are increasingly being treated by self-injection of biologic drugs. These are genetically engineered proteins derived from human genes, which are designed to inhibit the parts of the immune system that fuel inflammation.
Many of these medicinal products are viscous, so injecting them with a traditional syringe can be slow and painful because of their thick, sticky consistency. And the drugs often need to be refrigerated before use - so it takes time to safely warm them to room temperature before injection.
Product development firm Cambridge Consultants has developed a heated auto-injector concept which quickly warms medicine to body temperature (37°C) - reducing the viscosity and making it easier and quicker to deliver the dose. The technology has been coupled with innovative features and functions developed through the company's industrial design and human factors expertise. The result is a device that is easy for patients to handle - even with limited dexterity.
"The technology guides the patient through the injection process - with audible, visual and tactile signals at each stage and the needle hidden from view - allowing the drug to be warmed from fridge to body temperature in less than one minute and then reducing the injection duration by up to 30 per cent.
As well as being faster and easier to use, the new technology helps reduce the amount of discomfort associated with injecting drugs below body temperature - and could also help drugs disperse more rapidly into the body. Future applications of the technology could include cancer treatments, where there is an increasing trend towards self-administration.
