Monitoring the Canine Vaccine Cold Chain in the Field

Monitoring the Canine Vaccine Cold Chain in the Field

Abstract: The World Health Organisation stresses the importance of maintaining the cold chain for temperature sensitive vaccines. Due to the recommendation for rabies vaccines to be stored between 2° and 8° Celsius and the nature of canine mass vaccination projects, cold chain maintenance remains one of the most significant logistical hurdles project managers have to overcome.

Mission Rabies field teams in Picture4Malawi evaluated the use of adhesive temperature monitors as an alternative to thermometers in both storage fridges and field cooler boxes during the duration of a 4 week mass vaccination drive in April/May 2016.

Two different Timestrip® temperature monitors were used to alert the teams to the critical temperature thresholds of 0°C and 30°C.  As freezing rapidly damages vaccines, each vaccine box containing 10 vials of 10ml vaccine was marked with a monitor that indicates the immediate crossing of the lower threshold through colour change. As damage from high temperatures is related to both the temperature achieved and the time of exposure, to test for the upper temperature limit each cooler box was equipped with a monitor that showed the crossing of the upper threshold over time.

Of a total of 22 vaccination teams participating in the study, 7 teams reported an exposure of the vaccines to temperatures above 30°C for more than 4 hours and on 9 occasions teams reported a temperature drop to 0°C or below.

These findings highlight the importance of monitoring the temperature during field campaigns, both due to proximity to ice packs and exposure to high outside temperatures. The use of Timestrip temperature indicators gives early visual clues and raises awareness among the team. However practicability of the temperature monitoring must be taken into consideration and adhesive monitors need to be improved with regards to their setup to make them a valuable tool in field projects.

New Timestrip App: Digital Data Logger Performance at Analogue Prices

New Timestrip App: Digital Data Logger Performance at Analogue Prices

Time and Temperature Indicator maker Timestrip launches the Timestrip® Temperature app, a new tool that provides a visual audit trail of its temperature products.

Using the App simply involves taking a photo of a Timestrip® label with a smartphone.

If the Timestrip® has a new style serial number, the App will recognise the serial number and allow you to register it on the system.

You can then take a follow on scan where you can enter its activation state (inert, activated or breached), storing this data with essential time and location information in the cloud.

If the Timestrip® has an old style serial number you can still use the app in the same way but you’ll need to manually enter the serial number. The App is free to download from the Google Play store with an iOS version to follow shortly.

High tech low cost

The App is the latest innovation from Timestrip, which revolutionised the field of cold chain management with its unique Irreversible Time and Temperature Indicator labels (TTIs).

Recognised by the World Health Organisation and the US FDA as an essential tool for the cold chain management of blood and food products, TTIs provide data as to whether a blood or food product is safe to use. Timestrip’s irreversible TTIs make this crucial safety information unambiguous and instantly visible.

Like having a hundred permanent digital data loggers

The main benefit of Timestrip’s irreversible TTI labels is that they give essential cold chain management information on individual units of processed products. This deals with the main shortcoming of digital data loggers, which are mostly used for containers of transported and stored products.

Thanks to the new Timestrip® App, extra key information around cold chain management is added with the safe storage of status, time, journey and location data, which can be accessed at any time via the app or via a website. A digital data logger can be lost or damaged and all its data can be wiped clean. The Timestrip® App however safely stores this data in the Cloud.

Data logger functionality at a fraction of the price

Timestrip UK CEO Reuben Isbitsky says: “I am very excited about our first App, which brings Timestrip TTI labels very close to data logger functionality, at a fraction of the price.  While a key benefit of Timestrip products is that they do not need external infrastructure to read and interpret, using the optional Timestrip Temperature App to scan them, adds enhanced functionality, easy audit trail and provides the customer with a permanent record of the history of the product’s journey.”

Last Day of ISBT London 2015

The 25th Regional Congress of the ISBT London 2015 at the ExcEL Exhibition Centre is coming to a close and today is Timestrip’s last day exhibiting.

We have enjoyed the opportunity to show off our new 6°C blood temperature monitoring indicator, Blood Temp 6.

If you haven’t yet stopped by, take a moment to see a demonstration of Timestrip® Blood Temp 6 or Blood Temp 10 and pick up a sample to take home.

You can meet us and our range of blood temperature monitoring indicators at Booth 573 at the ISBT London 2015 exhibition.

ISBT London 2015

Our blood range indicators include both 6 and 10 degree ascending temperature indicators to extreme room temperature indicators.

Activated with simple finger pressure, Timestrip temperature indicators provide an easy to read indication of both activation and temperature breach.

Introducing Our 6 Degree Blood Bag Temperature Monitor

Timestrip is pleased to announce the arrival of our 6ºC blood bag temperature indicator– Blood Temp 6.
Blood Temp 6

Blood Temp 6 single use temperature indicators are low cost, field activated, and irreversible – they have been designed to be adhered directly to blood bags and are calibrated specifically to monitor the 6ºC threshold.

Blood temp 6 on blood transfusion bag

Use for monitoring temperature exposure when blood bags are in transit from storage, as in hospital blood banks. Blood Temp 6 provides a simple visual indication that blood has been stored and transported below 6 degrees Celsius.

Blood Temp 10

Along with our existing 10ºC product, Blood Temp 10, and our 25ºC Extreme room temperature indicator, Timestrip Plus 25ºC, Timestrip indicators are ideal for all your blood bag monitoring needs.
