Temperature monitoring in medical refrigerators

Medical products need chilled storage. Among these are anti-bodies, live vaccines such as insulin, or infusions.

In order to ensure their effectivity, they must be stored in a constant temperature range of +2 °C to +8 °C. If these upper and lower values are exceeded, the products can be damaged.

With testo Saveris, it does not need to come to this. If limit values are exceeded, it alarms the responsible people immediately, allowing intervention in case of emergency.

Industry challenge

Pharmaceuticals are extremely sensitive to temperature in many ways, mainly due to the proteins contained within them.

Freezing a medicine in which they are contained only once can already alter its composition so negatively, that its effectivity is reduced or even entirely lost.

In the worst case, toxic decomposition products can even be produced, which, in contrast to food contaminants are not externally identifiable, but which can cause equally serious damage.

However, not only medicines themselves or their component substances are endangered outside the permitted temperature range. Their containers or packaging are also affected.

Below-freezing or fluctuating temperatures can cause hairline cracks in ampoules and glass containers, or dissolve so-called leachable components out of the glass. The consequence can be contamination or even a loss of sterility.

In order to avoid this, those responsible on site rely on a measurement solution which automatically measures and securely documents the temperature values, functions reliably even in a power cut, and above all, immediately provides alarms when defined temperature limit values are exceeded, or when power - and thus the cold chain is interrupted.

The solution

The measurement data monitoring system testo Saveris was developed to meet the challenges of temperature monitoring in medical refrigerators.

The system is capable of redundant measurement data archiving and secure recording of measurement values, even in cases of power cuts, automated monitoring of temperature and air humidity and central documentation of data and comprehensive and automated report management.

It also offers multiple alarm options (SMS, e-mail, LED) when limit values are exceeded or he power supply interrupted and probes with internal and external sensors for flexible attachment on and in the refrigerator.
