Description

(I) Technical Field

[0001] This invention relates to the field of magnetic resonance imaging technology, and in particular to a fixation device suitable for magnetic resonance imaging of the spine of macaques. (II) Background Technology

[0002] Magnetic resonance imaging (MRI) is an advanced imaging diagnostic device, and specialized versions have been developed for animals.

[0003] Magnetic resonance imaging (MRI) systems are used for diagnostic scanning in animal experiments, but existing MRI systems specifically designed for diagnostic scanning in animal experiments...

[0004] The system has some drawbacks; it cannot effectively restrain animals during use, which may result in the animals moving around uncontrollably.

[0005] Furthermore, adjusting the animal bed frame typically requires manual adjustment, which is inefficient and inconvenient. Therefore, a practical...

[0006] It is essential to have a magnetic resonance imaging (MRI) scanner for precise animal localization. (III) Utility Model Content

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a special fixation device for magnetic resonance imaging of the macaque spine. The device includes: a monkey box, which is rectangular in shape with a slightly narrower head end, allowing the macaque to lie flat in a vertical position inside the box under anesthesia; and a monkey head and body fixation device, which is bolted to the left and right sides of the head and body ends of the monkey box, respectively. The device is retractable and consists of two parts: a rotating bolt and a baffle. The outer layer of the baffle is covered with a sponge cover. After the macaque is positioned correctly, the fixation device is rotated to fix the macaque's head and hips, thereby enabling magnetic resonance imaging of the macaque's spine.

[0008] As an improvement, the shape and proportions of the monkey box are close to those of an adult macaque.

[0009] As an improvement, the monkey boxes are all made of soft plastic.

[0010] As an improvement, the holes for fixing the monkey's head and body are positioned at the macaque's head and hip.

[0011] As an improvement, the monkey head and body fixing devices are both made of polycarbonate (PC) material.

[0012] As an improvement, the outer layer of the baffle in the monkey head and body fixing device is a replaceable sponge cover.

[0013] With the above structure, the present application has the following advantages: the present application can correct the body position of a macaque in a narcotic state by a monkey box, stably fix the head and hip of the macaque, prevent the lateral curvature of the spine, and ensure the imaging efficiency and quality of the magnetic resonance image, and the monkey box also plays a role of isolation from the examination bed to prevent the macaque excrement from polluting the equipment.
