Title:
電源投入ルーチンを有する医療装置
Document Type and Number:
Japanese Patent JP7308266
Kind Code:
B2
Abstract:
The present invention is directed towards a method for powering up a medical device (1) powered by a battery (2). The method includes executing an initial battery test. In the initial battery test, a difference voltage between a battery voltage measured without and with a test load is determined. The test load is favourable dimensioned not to significantly stress the battery. The difference voltage is compared with a difference voltage threshold, the difference voltage threshold being predefined in dependence of the no-test-load voltage. The method further includes providing an alarm if the difference voltage is above the difference voltage threshold.The invention further concerns a medical device that implements the before-mentioned method and a method for determining the relation between the difference voltage and the difference voltage threshold.The invention may be used to ensure that an alarm is provided if a newly inserted battery is too weak to power the medical device for the complete powering-up.
