Effective judgment of medical device circuit faults is the premise and basis for handling faults. It is necessary to ensure the efficiency and accuracy of judgments and provide good data support for maintenance personnel. At this stage, the methods for judging the fault of medical device circuits mainly include the following:
Detection method
The detection method refers to the use of professional fault detection level to judge the circuit faults existing in the medical device. In general, some large medical equipment, such as CT machines, centrifuges, etc., are accompanied by a corresponding self-test procedure, which can judge and analyze the cause of the fault when the fault occurs. Through the self-test procedure, it is also possible to detect and judge faults in some circuits.
2. Measurement method
The measurement method mainly uses a multimeter to measure the output voltage of each test point in the device circuit, and compares it with the standard voltage to determine whether there is a circuit failure. It should be noted that the premise of the application of the measurement method is that the maintenance technician must have a detailed understanding and grasp of the medical device, and can know the normal parameters of the device operation. This parameter can be provided by the manufacturer or a set of relatively stable data can be detected as a reference for fault diagnosis after the device is installed. In this way, when a circuit fault occurs in the device, the range of the fault can be analyzed by measuring the voltage of the test point, thereby determining the specific location of the fault.
3. Exclusion method
Mainly combined with the working principle of medical equipment and the performance of the fault, judge the cause of the fault, and then eliminate these reasons one by one in order of easy to difficult, until the last reason that can not be eliminated, is the fault The root cause. However, for a particular circuit, because it is in a medical device, it is more complicated to determine if there is a fault. In this case, the possibility of failure of the device component connected to the circuit can be eliminated first, and then the possibility of the device itself failure is eliminated, ensuring that the fault does exist in the circuit, and then combined with the exclusion method, the cause of the failure and the specific location Judge.
4. Replacement method
The replacement method mainly uses the means of component replacement to judge the circuit failure. First, the circuit that determines the fault is removed and installed in the same type of equipment. If the replacement equipment fails to operate normally, it indicates that the circuit is faulty. Correspondingly, normal circuits can also be connected to the faulty device to eliminate the possibility of component failure. If there are multiple identical circuit modules in the device, they can be replaced with each other to see if the fault has occurred, so as to judge whether the circuit is faulty.
