Description

  TECHNICAL FIELD The present invention relates to a remote maintenance system and method for a mobile medical device in which a medical device such as an X-ray diagnostic device, an X-ray CT device, or a magnetic resonance imaging device is mounted on a medical examination vehicle and can be examined. In particular, the present invention relates to a technique for improving the convenience of remote maintenance by acquiring position information of a checkup vehicle.

  Conventionally, when a medical device breaks down, the maintenance of the device in the hospital, the device installed in the examination car, etc. is contacted from the hospital to the sales office or service center, and then restored and repaired After collecting the information about the failure by telephone, the service staff who actually performed repairs actually went to the hospital. However, in this case, the exact degree of failure is not known until the service staff actually confirms the device. Since the investigation starts after the service staff arrives at the hospital, the downtime of the equipment becomes longer. However, there is a problem that it takes time to select a service person to be dispatched to the hospital where the failure occurred and to travel to the hospital.

  Currently, in order to alleviate the above-mentioned problems, devices in hospitals can use the network environment in hospitals to obtain device status and logs when failures occur via the Internet (hereinafter referred to as remote maintenance). Is popularized. When a failure occurs due to this remote maintenance, the contents of the failure can be understood even if there is no service person in the hospital, and the downtime of the apparatus is shortened. However, for devices that move outdoors, such as an examination car, remote maintenance cannot be used because there is no network environment to connect to the Internet. However, according to Patent Document 1, a method of acquiring device failure information using a mobile phone has been proposed.
