Detailed description of the invention

Below in conjunction with accompanying drawing and example, the invention will be further described.

As shown in Figure 1, a kind of diagnostic tester reacting obstacle medical treatment for elderly patients, structure comprises: Logic control module 1, test timing module 3, random pulses module 4, dynamic scanning displaying module 2, frequency division module 5 and key-press module 6 and indicating module 7, described frequency division module 5 and test timing module 3, random pulses module 4, dynamic scanning displaying module 2 is connected by circuit, test timing module 3 is connected with random pulses module 4 andlogic control module 1, described indicating module comprises ready light 8, test display lamp 9, overflow lamp 10, fault display lamp 11, buzzer 12, key-press module 6 comprises stimulus selection key, test starts button, reaction button.
