AI Technical Summary

Technical Problem

In existing technologies, patient movement during MRI scans can lead to unclear images, and current belt control methods cannot effectively limit the patient's breathing range and body movement.

Method used

The device uses a support, assembly box, and adjustment mechanism in conjunction with a compression mechanism. The height and position of the compression mechanism can be adjusted by the adjustment mechanism. The upper and lateral compression parts fit against the patient's abdomen. Combined with positioning and pre-locking components, stable compression and limitation of the patient's abdomen can be achieved.

Benefits of technology

It improves patient stability during MRI examinations, reduces the impact of respiratory amplitude and body movement, and ensures image clarity.

Abstract

The present application relates to the technical field of medical devices, in particular to a respiratory amplitude limiting device for abdominal magnetic resonance, comprising a support, an assembly box connected with the support, and an adjusting mechanism arranged in the assembly box; a pressing mechanism is connected with the lifting end of the adjusting mechanism, and the adjusting mechanism is used for adjusting the horizontal and height positions of the pressing mechanism; the pressing mechanism comprises an upper pressing part and a side pressing part, and the upper pressing part and the side pressing part are connected and fit the upper lateral abdominal curve of a human body in a lying state; through the rapid adjustment of the adjusting mechanism on the pressing mechanism, effective compression and blocking of the abdominal part of the patient in a lying state can be formed by the pressing mechanism, which can reduce the influence of the respiratory amplitude of the patient on the examination on one hand, and avoid the lateral movement of the patient on the other hand.
