All,

I am trying to solve the following problem...

We have small medical teams that travel to remote locations, to deliver vaccines to patients.

Many of the routes are through jungle, mountains, dessert, etc and take several hours or longer to reach to destination.

The teams use motorbikes, and walking through rough terrain to get to the destination.

During the traveling, there is no way to tell what's going on in the cooler until the team reaches the destination.

We've been asked to:

  1. Track cooler location in real time
  2. Track cooler temperature in real time

This looks like a solvable IoT problem.

Look forward to getting experiences and insights on this.

Thanks

Hi Kiwanis,

With proper monitoring you would probably find that the vaccines are being kept cold enough for a one-day vaccination program. This could be verified by looking at the VVM’s on the transported vaccines. I would be interested to know what the VVM’s are indicating.

The life of the cooler could be further extended by wrapping the carrier in a wet towel. Evaporative cooling will than slow the melting of the ice packs.

Our previous entry suggested a digital monitoring device which would use the same algorithm as the VVM to determine loss of life of the vaccine. Its use would eliminate the need for transmitting temperature data since the impact of temperature excursions would be clearly indicated on its display.

Regards,

Larry

Hello,

Would a portable refridgerated pack that is operated on continuous 24/7 off grid electricity be useful. The refridgerated area is 1.5 litre or 180mm x 100mm x 80mm, would this be big enough for daily vaccination projects. Having wifi and 4G connectitiy that allows remote temperture checking and remote temperature control be a benefit? Would it be a requirement for this portable system to be IP65 water and dust proof and have antishock protection? Would returning with blood samples under the same temperature control be a benefit to your program?

Please let me know your requirements, I maybe be able to assist.

Cheers

Steve

Dear Dion Rachelson

This sounds interesting.Would you please email me so that we can discuss further?

Hi,

It is my understanding that one of the things you are trying to accomplish is to see what effect temperature excursions during a delivery have on the life of a vaccine. We have been promoting a device which would accomplish this; it is based on MKT temperature. However, the user would need no knowledge of this concept. For a VVM2 vaccine, for example, the device would display the life of a new VVM2 vaccine when stored at 8 deg C and also the life of a new vaccine when stored at the temperature experienced during the delivery of the vaccines. If for example, during a two day journey the temperature of the vaccines gradually went from 4 deg C to 20 deg C. The display would show that a new VVM2 vaccine would have a life 105 days and a life of 25 days when stored at the conditions encountered during the 2 day journey. If the vaccine was to be used on the second day the efficacy of the vaccine would not be affected even if the vaccine had initially lost most of its life. These results indicate that the trip may safely be extended to a third day. If at the end of the third day the vaccine temperature climbed to 25 deg C. The display will show under the temperature excursion encountered for 3 days the life of a new vaccine will be 20 days. This result shows that with vaccines that had more than 20 percent of their life initially, the trip could be extended to 3 days. The efficacy of the vaccine could be confirmed by the dot on the VVM. Using the typical alarm setting the trip would have been terminated in less than 2 days. This device would be small, light and easy to interpret. The results could further show that unused vaccines may be able to be safely transported back to the clinics. Incorporation of this monitoring could save time and money.

Dear Sir,

Please send me an email to [email protected] with your contact detail, I would like to discuss opportunities we could offer for your project.

With thanks and regards

Dear Sir,

 There is a French Company OCEASOFT.

They have a small Bluetooth Device that can be put in the Vaccines Carrier Cold Boxes. If you have a Bluetooth Phone (most of the phones do), data can be checked whenever you need and uploaded by GSM to the server.

Worth having a look at.

Beyond Wireless Technology has a monitoring device that does just this.  It is called a BeyondCom Ice3. This datalogger is battery operated, and has a built in SIM card.  The unit is setup for the desired alarm thresholds on a web portal (ColdCloud).  As soon as the temperature goes out of range e.g. 8 deg C for a designated time, the unit will immediately connect and send SMS's to designated recipients.

The unit has built in GPS as well.

If you want more information, you are welcome to contact me.

Kind Regards,

Dion Rachelson

The workers have phones but old, non-smart phones from around 2003 and all different makes and models. UNICEF currently has an SMS-based system for recording data but I am interested in realtime temperature monitoring and collection of that data in AWS, as an example. I am excited about creating an IoT solution with a microcontroller with builtin SIM card  but wanted to make sure nothing like this already exists. I have not seen anything yet but that doesn't mean it's not our there.

Put tracker in vaccine carrier and track their geolocation. Cold chain monitoring devices like data loggers with alarms can be used. Data can be recorded once health worker reaches health facility where he can connect and recods temperature from data loggers or centrally can be connected to get live alarms for lower or higher temperatures out of the given range.
