The device enables people without medical experience to collect and transmit a distant patient's vital signs - blood pressure, pulse and heartbeat - to waiting doctors.
Tempus 2000 is designed for use on aircraft, ships or other remote locations where there is no access to mains power.
The long-life, reliability and excellent charge retention of Saft MP series Li-ion batteries were key reasons for their being chosen to power this vital life saving equipment.

Saft's new 9V primary (non-rechargeable) lithium batteries have twice the capacity of standard alkaline equivalents, doubling the life between battery changes of equipment.
Lithium primary cell gives a 12% capacity boost
Saft's new LS 33600C primary lithium cell has a nominal capacity of 18.5Ah, 12 per cent higher than Saft's existing high-capacity D-size lithium cell.
The fact that Saft batteries have already been certified by the British Civil Aviation Authority (CAA) and major airlines is another major benefit.
The in-flight Tempus 2000 has already proved itself in service - on a recent British Midland International flight from Chicago to Manchester a passenger fell ill and an electrocardiogram (EGM) was quickly taken and sent to doctors in the USA.
The doctors were able to give informed care advice to the cabin crew.
The Saft Li-ion MP battery that powers the Tempus 2000 is used in many civilian and military portable and standby applications where fail-safe operation is essential.
A key advantage of the MP cell is its unique rectangular shape which gives it an extremely high capacity by utilising the volume lost when conventional cylindrical cells are packed together - a single prismatic cell has some 20% higher volumetric energy density than an equivalent pack of cylindrical cells.
Saft's lithium-ion electrochemistry uses a graphite negative electrode and lithiated cobalt oxide positive electrode.
Operating temperatures range from -40 to +60C (in discharge) while another vital factor for RDT is that the cell will still retain 95% of its charge after one month's storage.
And one recent example indicated that even after a year without use the battery retained enough power for at least 3h continuous use.
The MP cells also offer a long service life and will retain 85% of their initial capacity after 500 charge-discharge cycles, and 75% after 1000 cycles.
Saft is a company whose batteries have existing approval from the Civil Aviation Authority (CAA) and whose products are widely used in demanding civil and military applications.
One reason that RDT came to Saft with its Tempus 2000 was that Saft batteries are certified not just by the CAA, but also by related European, American and Russian civil aviation authorities.
In fact, Saft's lithium primary batteries were the first to be CAA-approved.
Saft knows the CAA approval route, and helped RDT obtain in-flight approval for the battery-related aspects of its medical kit efficiently.
Says RDTs managing director, Graham Murphy, "With Saft's competence in airworthiness approvals, we were able to get the Tempus 2000 on a number of British airlines faster, since Saft knew the battery hurdles for aviation authorities".
With Tempus 2000 and its Saft Li-ion MP batteries, experts can consult on emergency situations from sites anywhere in the world - in just minutes - from the air, at sea or elsewhere.
The device is powered by a Saft battery with four series-connected MP 176065 3.6V cells which provide a nominal capacity of 24Ah.
It is safe and reliable thanks to a ruggedised case and customized electronics.
The battery's "fuel gauge" indicates the state of charge on an LED.
The patient treated on the recent transatlantic flight was successfully cared for and recovered and commented: "I was amazed at how quickly the flight attendant reacted, and how quickly the equipment was set up and information communicated".
The MedLink ground-based physician working on the case said: "The ECG was virtually the same quality as what I see in the emergency room".
MedLink is the world's leading response centre for the aviation and other industries.
The airline's chief medical officer added, "We've used Tempus many times, I'm delighted that this was so effective". Request a free brochure from Saft Lithium Battery Division ...
