Medical equipment oxygen tank

Korean patients went for MRI and were killed by flying oxygen bottles. The accident is the negligence of the hospital, and the hospital should bear most of the responsibility. A 60-year-old patient who was undergoing MRI scanning in South Korea was hit in the head by a 60-kilogram oxygen bottle, and was sucked into the machine because of its strong magnetic force, resulting in an abnormal accident and death. The unnamed man was taken to the MRI ward of a hospital in the southern city of Jinhai on Thursday night. He is in critical condition. According to the doctor, this man suffers from epilepsy. We are investigating the reason why oxygen cylinders were brought into the room. Superintendent Cui Taiyong told Hong Kong news media South China Morning Post, adding that the built-in oxygen supply system may be out of order.

We will thoroughly investigate the incident to determine whether human error is involved. He added. Authorities say that because of the strong magnetic force, there are generally no metal objects around? ,? The hospital also knew this, but explained that the patient was in critical condition and failed to take the oxygen bottle in time. The magnetic field of the MRI scanner is 60,000 times stronger than that of the earth, which will attract metal objects and make them float in the air. It is worth noting that a similar tragedy happened in Mumbai, India. A 32-year-old man who visited his mother-in-law in Nair Hospital died because the oxygen bottle was pulled into the MRI hole. Later, it was reported that the metal detector in the room could not work normally, and a hospital staff member was on the phone when the accident happened.

Superconducting magnet of nuclear magnetic resonance equipment will produce strong magnetic field and electromagnetic field, which will interfere with the function of cardiac pacemaker. Users of pacemakers and other implantable ferromagnetic medical devices are advised to consult their doctors, pacemaker manuals and pacemaker manufacturers before entering facilities equipped with MRI equipment. Post clearly visible warning signs in areas with strong magnetic fields, measure stray fields with Gauss meter, and restrict the public from entering areas of 5 Gauss or higher.

The strong magnetic field will suddenly pull the unconstrained magnetic objects nearby into the magnet with considerable force. Keep all tools, equipment and personal items containing ferromagnetic materials (such as steel and iron) at least 2 meters away from the magnet. Although it is not a security problem, it is suggested that users can erase magnetic media such as tapes and floppy disks, disable credit cards and ATM cards, and damage analog watches. Avoid skin contact with low-temperature (liquid) helium and nitrogen, and wear protective mask and loose warm gloves when maintaining and handling frozen samples in Dewar bottles.
