Description

Technical Field

[0001] The utility model relates to the technical field of nuclear magnetic resonance inspection, in particular to a magnetic resonance inspection fixing device. Background Art

[0002] When patients undergo an MRI examination, they often need to lie flat on the examination bed. However, since the MRI examination takes a long time, the patient's feet are prone to move when lying on their back for a long time, causing the bilateral ankles to move back and forth, which in turn drives the legs to rotate and affects the examination results. Utility Model Content

[0003] The purpose of the utility model is to provide a magnetic resonance examination fixing device to solve the problems raised in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a bottom plate, positioning teeth, a limit plate, a limit groove, and limit plate teeth; the bottom plate is placed at the end of the examination bed, and a front side surface thereof is symmetrically provided with a plurality of rows of positioning teeth along the center; the limit plate has two pieces, an arc-shaped limit groove is opened in the center of the front side surface, and a plurality of rows of limit plate teeth cooperating with the positioning teeth are provided on the rear side surface; the bottom plate and the limit plate are made of foam plastic; the gaps in the limit groove are filled with silk cotton and foam when in use.

[0005] As a preferred technical solution of the present utility model, the limiting plate is at the same height as the bottom plate.

[0006] As a preferred technical solution of the utility model, the positioning teeth on the bottom plate are arranged symmetrically.

[0007] Compared with the prior art, the beneficial effects of the utility model are: the patient's ankle is fixed by the limiting groove in the limiting plate, and the gap is filled with silk cotton and foam to keep the patient's legs fixed during a long examination; the positioning is performed by the positioning teeth and the limiting plate teeth, and the position can be adjusted according to different patients. It is simple and convenient to use and has low production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Example 1

[0012] like Figure 1 to Figure 2As shown, the utility model discloses a magnetic resonance examination fixing device, including a bottom plate 1, positioning teeth 2, a limiting plate 3, a limiting groove 4, and limiting plate teeth 5; the bottom plate 1 is placed at the end of the examination bed, and a plurality of rows of positioning teeth 2 are symmetrically arranged along the center of the front side surface; the limiting plate 3 has two pieces, an arc-shaped limiting groove 4 is opened in the center of the front side surface, and a plurality of rows of limiting plate teeth 5 that cooperate with the positioning teeth 2 are arranged on the rear side surface. The limiting plate 3 is of the same height as the bottom plate 1, and is fixed by the mutually cooperating positioning teeth 2 and the limiting plate teeth 5. The positioning teeth 2 on the bottom plate 1 are arranged symmetrically on the left and right to provide support when the patient's ankle is everted.

[0013] The working principle of the utility model is as follows: when a patient undergoes an MRI examination, the position of the limit plate 3 is first adjusted according to the patient's body shape so that the limit plate teeth 5 are inserted into the positioning teeth 2, and then the patient's ankle is placed in the limit groove 4, and the gap is filled with silk cotton and foam to ensure that the patient's ankle is fixed, and the MRI examination can be performed normally.

[0014] The utility model fixes the patient's ankle through the limiting groove in the limiting plate, and uses silk cotton and foam to fill the gap, so that the patient's legs can be kept fixed during a long examination; the positioning is limited by the positioning teeth and the limiting plate teeth, and the position can be adjusted according to different patients. The use is simple and convenient, and the production cost is low.

[0015] Although the specific embodiments of the present invention are described in detail above, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the field without departing from the purpose of the present invention, and modifications or deformations without creative labor are still within the scope of protection of the present invention.
