Description

An MRI examination table

technical field

The utility model belongs to the field of medical equipment, in particular to a nuclear magnetic resonance examination bed.

Background technique

Nuclear Magnetic Resonance is to use the characteristics of the spin motion of atomic nuclei to place the human body in a special external magnetic field. The hydrogen nuclei in the human body are excited by radio frequency pulses, causing the hydrogen nuclei to resonate and absorb energy. After the radio frequency pulse is stopped, the hydrogen nuclei press It is a method of transmitting electrical signals at a specific frequency and releasing the absorbed energy, which is recorded by an external receiver and processed by an electronic computer to obtain an image. In the field of modern medicine, nuclear magnetic resonance examination has become one of the routine examinations, and more and more patients need to undergo nuclear magnetic resonance examination.

The existing nuclear magnetic resonance examination bed has a simple structure and is integrated with the main machine of the nuclear magnetic resonance. It is inconvenient to use, and the bed body is relatively high. The patient needs to use steps to lie on the examination bed. The transfer is extremely inconvenient, which increases the workload of medical staff; in order to keep the examination bed clean, a disposable surgical bed sheet is usually spread, but there is no fixing device on the bed body. Displacement will not achieve the effect of preventing pollution; MRI requires patients to have a high degree of cooperation, shaking of the head and limbs can cause serious movement artifacts, resulting in failure to complete the examination, for some patients with impaired self-control or head Patients in the forced position need appropriate auxiliary fixation, and the high-field MRI noise is relatively loud, generally between 65-95 decibels, and individual sequences can reach 100 decibels. Although it is within the safe range, it is still unbearable , a small number of subjects will appear temporary tinnitus, temporary hearing loss and other symptoms.

Therefore, it is necessary to improve the existing nuclear magnetic resonance examination bed, so that the structure of the nuclear magnetic resonance examination bed is more perfect, meet the examination needs of patients, and reduce the workload of medical staff.
