Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a safety isolation and blocking device for a nuclear magnetic resonance examination room. Background Art

[0002] Magnetic resonance imaging (MRI) is an advanced medical imaging technique that uses strong magnetic fields and radiofrequency pulses to perform non-invasive examinations of human tissue. Unlike traditional X-rays or CT scans, MRI does not produce ionizing radiation. Instead, it generates high-resolution cross-sectional images by detecting the resonance signals of hydrogen nuclei in the human body in a magnetic field. MRI has excellent soft tissue contrast and can clearly display structures such as the brain, spinal cord, joints, and muscles. It is widely used in tumor diagnosis, neurological disease assessment, and sports injury examinations. In addition, MRI can also perform functional imaging (fMRI) and angiography (MRA), providing more comprehensive physiological information. The examination process is safe and painless, but it is important to note that metal implants in the body (such as pacemakers and metal prostheses) may affect the examination or pose a risk, so the doctor should be informed in advance. MRI is an important tool for precise diagnosis in modern medicine and provides a key basis for clinical treatment.

[0003] In the prior art, when patients undergo an MRI examination, medical staff need to ask whether they have a pacemaker or carry any metal objects on their bodies, and the patients need to answer by themselves. However, some patients are seriously ill and forget about the steel plates or nails that have been fixed on their bodies for a long time. If the patients do not answer after the medical staff asks, it will cause serious medical accidents. Therefore, it is necessary to perform safety isolation detection operations to improve the safety of the examination. At the same time, some patients' families may be anxious during the examination and may step over the isolation door to check the internal situation before the isolation door is completely closed. However, the family members may still have metal materials on their bodies, which will seriously affect the inspection operation and make it impossible to stop illegal intruders, causing inconvenience in the use of the existing inspection room safety isolation barrier.

After moving, the entrance and exit of the MRI can be isolated. Then, when an illegal person breaks in to check the internal situation of the MRI, the isolation door 102 is opened. At this time, the blocking door 2 cannot be opened without the operation of the control panel 201. When medical staff enter and exit the room, they can use the control panel 201 to perform face or password verification. When the verification is successful, the internal motor of the first motor protection box 202 will drive the rotation of the gear body 607, which will engage with the rack body 608 after rotation to realize the bidirectional movement of the two rack bodies 608.
