Device enables easy injection in emergencies

CBL's spray-drying technology is only one of a family of complementary developments aimed at revolutionising the way vaccines are made, distributed and used.

If a global epidemic were to break out or a bioterrorist attack to be launched, speed of vaccination would be crucial to preventing the spread of disease and to survival rates among the population. CBL has also developed a patented delivery device that enables injections to be given by untrained people such as teachers, policemen, firemen or village elders.

The telescopic device contains a small, prefilled syringe and has a small hole in the base covered by an adhesive transfer foil to keep the needle sterile. When the label is removed, the adhesive remains on the device and enables it to stick to the patient's skin.

As series of 'snap tabs' break off successively as the top of the device is depressed, allowing the needle to puncture the skin and the dose to be injected. When the plunger bottoms out, a spring withdraws the needle into the barrel, making the device safe and non-reusable.

To date, CBL is having the first 25 working prototype devices made. It will then work with partners to commercialise, manufacture, fill and distribute the device. Suitable for stable or standard injectable liquids, the device has a number of potential uses, ranging from insulin and antidotes to chemical weapons to antivenoms and even OTC vaccines for developing countries.
