Claim:
A method for automatic self-test of a medical device comprising the steps of: detecting whether the medical device has reached an automatic self-test time set in a last time, when the medical device is in a power-off state; initiating the medical device to perform an automatic self-test according to determined automatic self-test items, if the result of the detecting is affirmative; detecting the result of the automatic self-test; judging whether there is any abnormal item in the medical device based on the results of the automatic self-test; determining the automatic self-test time of a next time for the medical device based on the result of the automatic self-test, wherein determining the automatic self-test time of the next time comprises setting a time interval with relatively low probability of using the medical device in a day that is a first time interval apart from the time of the current automatic self-test in the future as the automatic self-test time of the next time, if the result of the judging is negative; and determining the automatic self-test items of the next time for the medical device based on the result of the automatic self-test, wherein determining the automatic self-test items comprises setting all available automatic self-test items in the medical device as the automatic self-test items of the next time, if the result of the judging is negative, and wherein determining the automatic self-test items comprises setting a sub-group of automatic self-test items corresponding to frequently used functions of the medical device as the automatic self-test items of the next time, if the result of the judging is affirmative.
