For a long time, magnets have been a key component of many different medical technologies. Of course, the most famous is nuclear magnetic resonance imaging (MRI), which was first developed in the 1970s and 1980s. In addition, magnets can be found in many other medical devices, although their role is little known.

Magnets are used for magnetic switches, blood separators, hospital water filtration systems, laboratory tests, ventilators, insulin pumps, etc. the use of magnets in medicine can improve the level of patient care and greatly help medical personnel perform important life-saving work.

In each floor of the hospital, magnets can be found to assist patient care. In addition to supplying power to ventilators, permanent magnets are also used to supply power to heart pumps and other equipment.

The application of magnetic bearing in heart pump improves the reliability of the pump, prolongs its service life and reduces blood damage to the greatest extent.

NMR and magnet

In the surgical ward of the hospital, new technologies using magnets to simplify and simplify the surgical process are being developed, such as creating anastomosis. In magnetic compression anastomosis, a special rare earth magnet is placed to compress a section of tissue to form an anastomosis. This experimental medical technology has created a very ideal alternative to the traditional method, that is, the use of manual sewing or stapler. It has been found to be a faster way to complete the procedure and happier patient rehabilitation. In general medical applications, magnets are also used in holding systems and many different pump and filtration systems.

Magnets are also used in technologies to improve people's daily life under certain conditions. For deaf people who choose to use artificial cochlea, magnets are used to fix the head of the cochlea in order to effectively transmit sound to the inner cochlea. Magnets are also used in the dental field for applications such as auxiliary retention dentures. For people using prosthetics, the magnetic prosthetic suspension system helps to maintain the position of the prosthetic, improve the overall comfort and reduce the need for prosthetic maintenance.

There are many ways that magnets can be used in medical technology, and researchers are very interested. They need to develop more ways to apply the power of magnets.
