Portable Vaccine Carrier - Emvolio

Our portable vaccine carrier is battery-powered refrigeration device that will strictly maintain a pre-set temperature for up to 12 hours for last-mile transport of vaccines. Further device capabilities will include continuous temperature monitoring, location tracking, state of charge indication, and communication with headquarters via live tracking and vital statistics for improved coverage. This device will reduce the economic burden of wasted vaccines and optimize human resources in vaccine delivery by nullifying the need for repeated immunization visits to account for the administering of unviable vaccines. Importantly, the level of portability and ease of charging that it gains from being battery- powered sets apart from the competition, which relies on less efficient and impractical means, such as frozen PCM, use of Ammonia or refrigerants, to generate cooling.

However, as things stand, there is no accountability for the samples once they are dispatched from collection centers to the central laboratory for testing. Cold-chain transport systems that rely on ice-based technologies face problems of compliance, accidental freezing and/or warming, and lack of temperature monitoring during transit. Chilled transport media are often unreliable due to power outages and human error during freezing of ice/gel packs, leading to the risk of compromised testing resulting from specimen drying, contamination or degradation.

Our device has a patented rapid-cooling technology that ensures temperature stabilization to safe-limits over 96% faster than ice-based technologies, during temperature excursions (arising from operational requirements or human interference). In practical terms, this means minimal freeze-thaw cycles for the specimen and thus accurate results from testing. The rugged 2 liter-capacity cold chamber (as per WHO standards) is designed with dual-layered stainless steel 304 for corrosion resistance and easy sterilization.
