As one of the work of clinical engineering technicians, we have maintenance and inspection of portable medical equipment operating in hospital.Originally, it is desirable to operate the medical device within the service life stated in the package insert or instruction manual, but in reality it is operated for a long time while repairing it.
This time, the device to be analyzed is "automatic infusion pump".Sometimes the patient carries it, there is a limit to management on the medical staff side.It is also one of the devices that are difficult to manage because there are many units.Many of repair and inspection requests are accidents such as falls and bringing in the MRI room (high magnetic field environment).In some cases repair expenses become high enough to purchase, and operation is canceled within the service life.The cause of discontinuation is not only aged deterioration.We believe that when buying it is not the end, we should also consider the next update time together.
On the other hand, in order to establish a business within the budget, even if assertion of aged deterioration, it is sometimes leaked from plan update.The problem is the balance between risk and expense.To obtain budget, we must show reasonable grounds.
This time, we predicted the number of annual shutdowns based on maintenance data.We report on the prediction of equipment life in field data and its application.
