[0029] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.
[0030] Please refer to Figures 1-4 This invention provides an embodiment of a magnetic resonance water model fixing and protection device, comprising a base 1; four baffles 2 are disposed on the base 1, the base 1 supports the four baffles 2, the four baffles 2 are sequentially spliced together with the base 1 to form a placement cavity 3 for accommodating the water model; part of the inner wall surface of the baffles 2 is provided as an elastic surface 21, the elastic surface 21 is made of an elastomeric material, the baffles 2 are hollow structures, the baffles 2 have an air inlet 22, the air inlet 22 is provided with a valve core, the air inlet assembly 4 can inflate the baffles 2 through the air inlet 22, so that the elastic surface 21 protrudes into the placement cavity 3 and fits against the water model, ensuring that the water model is stably fixed in the placement cavity 3, effectively solving the problem of water model not being easy to fix during nuclear magnetic resonance scanning.
[0031] In other embodiments, the number of retaining walls 2 can also be set to other values, based on the requirement that the formed placement cavity 3 can accommodate the water model.
[0032] It should be noted that both the base 1 and the retaining wall 2 should be made of magnetic resonance-compatible non-magnetic materials to avoid affecting the calibration of nuclear magnetic resonance.
[0033] For details, please refer to Figures 1-3 The retaining wall 2 is preferably perpendicular to the upper surface of the base 1, and the resulting placement cavity 3 facilitates the removal and placement of the water mold.
[0034] In this embodiment, please refer to Figures 1-4The elastic surface 21 includes multiple hoses distributed along the direction close to or away from the base 1. Correspondingly, the retaining wall 2 has channels that are respectively connected to the two ends of the hoses, so as to ensure that the hoses can expand when the inflation assembly 4 is inflated.
[0035] Further, please refer to Figures 1-4 The hose is preferably a corrugated tube, which has a good expansion effect when the inflation component 4 is inflated; in other embodiments, the surface of the hose can also be a smooth surface, as long as it can expand effectively when the internal air pressure increases.
[0036] Furthermore, please refer to Figure 4 On the outer surface of the retaining wall 2, there are fixing pins 23 at both ends of the hose. A fixing rope (not shown in the figure) is provided between the two fixing pins 23. The fixing rope can effectively limit the position of the hose, prevent the hose from shaking when it expands, and allow the hose to expand more into the placement cavity 3, thereby improving the fixing effect on the water model.
