As the transplant can be stored during the whole life of the child, the method of storage is one of the most important criterions.

          Each transplant is divided into minimum of two parts. Every part of the transplant is stored separately, which explicitly decreases the probability of the whole transplant being destroyed. For instance, if the probability of the damage during 100 years in one store is 1:10 000, the storage in two stores decreases the probability of damage to 1:100 000 000.

          Our storage spaces are located and constructed so that there would be no risk of damage by fire, flood, landslide, or earthquake (for instance only non-inflammable materials are used, with exception of the electrical wires, which fire would not increase the temperature so high that the transplants could be damaged). Further we looked for a location with the lowest rate of criminality. The storage rooms are protected against vandalism by a security system connected to the employees and the police.

The transplants are placed in the biological containers with a liquid nitrogen pool. The released vapour of the nitrogen keep in the container the temperature near to -196°C. So this system is fully independent from any electrical power, or from another form of energy. The amount of the liquid nitrogen and the temperature in the container is controlled by the monitoring system, which informs entrusted employees about any failure by phone. This, together with other electronic security systems, has a source of backup power. It means that a power cut neither influences the temperature, nor the security monitoring systems. Moreover, the appointed employee monitors the status of liquid nitrogen and the containers in periodic time intervals. The liquid nitrogen is filled up from supply containers. These are then filled up directly by the liquid nitrogen suppliers. In accessible distance (up to 200 km) from the store rooms there are 7 independent production units of liquid nitrogen. In Slovakia, Austria, Hungary and Czech Republic, so also any let down by the liquid nitrogen supplier could be solved immediately.

The transplant itself is hermetically closed, so it cannot be infected. Each transplant is in the quarantine at first, while it is tested for the most serious infectious diseases and only then is it definitively stored together with other transplants (about 100 transplants are stored together).

Be informed:


• If the transplant is divided into at least two parts
• If the single parts of the transplant are preserved separately
• If the storage rooms are protected against fire and against another possible damage
• How they are protected against intentional damage
• What the control mechanism and procedures are for container damage
