Problems solved by technology

[0003] However, because the MRI examination takes a long time, it is still difficult to keep the head position still by the examinee's own will, and the slight movement of the examinee's head will easily make the noise-proof earphones worn on the head and the metal shell of the combined coil Collision, the ear cannot fit normally, and the earphones cannot normally play a noise-proof role, and the huge noise also causes discomfort to the examinee, making it more difficult to keep the head still

Abstract

The invention discloses a head fixing device for magnetic resonance examination. The head fixing device comprises a shoulder-neck pad, a head pad and a head fixator, wherein the shoulder-neck pad comprises a shoulder pad part and a neck pad part, and the shoulder pad part and the neck pad part are connected; the head pad comprises a bottom and a surrounding part; the surrounding part partially surrounds the bottom and is connected to the bottom; the part, which is not surrounded by the bottom, is connected to the neck pad part; the head fixator comprises an inflating part, a head face fit partand an accommodating part; the inflating part comprises an airbag and an inflating device; one side of the airbag is connected to the head face fit part and the other side is connected to the surrounding part; the inflating device is connected to the airbag; and the accommodating part is formed on the head face fit part. With the application of the head fixing device provided by the invention, the head position of an examined object can be fixed, and the head fixing device can adapt to heads of various examined objects; and in addition, the position of a de-noising headset can be also fixed,so that the de-noising headset can be prevented from moving easily and can fit to ears of the examined object.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a head fixation device for magnetic resonance examination, a magnetic resonance head-neck combined coil and a magnetic resonance imaging system with the fixation device. Background technique [0002] During an MRI examination, the examinee is usually required to lie supine on the examination bed, wear noise-canceling headphones, rest the head in the MRI head-neck joint coil, and keep the head position still for examination. The existing magnetic resonance head and neck combined coil is provided with a protective pad, which allows the examinee's head, shoulder and neck to not directly contact the plastic shell of the combined coil, but to lie on the protective pad made of soft elastic material, which can be To a certain extent, the comfort of the examinee's head, shoulders and neck is improved. [0003] However, because the MRI examination takes a long time, it is still d...
