Objective    To design a multifunction platform for medical experiments.     Methods    Sensors and controllers of temperature

humidity

oxygen and carbon dioxide concentration were used to make the platform for medical experiments. The relative criteria of this machine were tested. The cell lines 293 and PK15 were used to test the potential usage of the platform.     Results    The temperature

humidity

oxygen concentration

carbon dioxide concentration in this medical experimental platform were well controlled. The range of temperature control was from -20 to +60 ℃

the range of carbon dioxide concentration  control from 0％ to 20%

the range of oxygen concentration control from 0％ to 100%. The range of humidity control was from the humidity at room temperature to 98%. The morphological changes of 293 and PK15 cell lines could be found when temperature went down as designed.     Conclusion    The temperature

oxygen concentration

carbon dioxide concentration and humidity of storage chamber can be intellectually controlled. This apparatus can be used for graft storage-related test.
