The first aborted CT hospital is not at fault. The second time from the legal sense strictly speaking CT machine damage if force majeure caused by the hospital is not caused by the hospital will not recognize any responsibility. The key is the third time, the hospital is in what point of view to prevent you from transferring to the hospital? Although from the medical common sense point of view, patients who have suffered a cerebral hemorrhage are indeed not suitable for big shocks, in a sense it is also correct. So from your brief description, it is more complicated and involves a wide range of legal provisions, if you are determined to seek justice, it is recommended to find a lawyer to consult with the better.
From the relevant provisions of the law, the hospital has the responsibility to keep all jurisdictional equipment in good working order, in addition to force majeure factors, the hospital should be responsible for the harm caused by the equipment to patients.
So personally, I still recommend that you consult a lawyer, so that he can tell you to fight the lawsuit to win geometric; how to do legal forensics and so on.
