[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] An auxiliary device for MR detection includes a base plate 1 for a patient to lie flat. When using the device, the base plate 1 needs to be placed on the MR detection bed. A head fixing component 2 is arranged at the front end of the base plate 1. The head fixing component 2 is used to fix the patient's head during the examination to prevent the head from shaking and affecting the examination. The head fixing component 2 includes a support plate 201 fixedly arranged on the base plate 1. A cavity is arranged in the support plate 201. Guide rails 202 are arranged on both sides of the cavity. A first slider 203 that can move laterally is arranged in the guide rail 202. A rotatable first connecting rod 204 is arranged in the middle position of the cavity. Both ends of the first connecting rod 204 and two first sliders 203 are hinged through a second connecting rod 205. Driven by the second connecting rod 205, the first connecting rod 204 can drive the two first sliders 203 to move simultaneously when the first connecting rod 204 rotates, and the moving directions are opposite.
[0027] The upper ends of the two first sliders 203 are both provided with connecting rods 206, and the upper ends of the connecting rods 206 penetrate through the upper wall of the cavity and are connected with clamping members 207. The two clamping members 207 are arranged opposite to each other and cooperate to fix the head. Driven by the first slider 203, the two clamping members 207 move simultaneously and approach each other, and can clamp the patient's head. Since the distance between the two clamping members 207 gradually decreases, it can adapt to heads of different sizes, and when clamping the patient's head, only one of the clamping members 207 needs to be pushed, which is convenient and quick. A first screw hole is provided on the side wall of one side of the cavity, and a first screw rod 209 is screwed in the first screw hole. The front end of the first screw rod 209 contacts one of the first sliders 203. The first screw rod 209 can limit the first slider 203 after clamping the head, so as to ensure that the patient's head will not be separated from between the two clamping members 207 when shaking.
[0028] A pillow 208 is provided on the upper surface of the support plate 201 between the two clamping members 207. During the examination, the patient's head needs to lie on the pillow 208, and the patient's head can be clamped. Furthermore, an arc-shaped groove that matches the patient's head is provided on the inner side of the clamping member 207 to ensure that the clamping member 207 is closer to the patient's head. Furthermore, a cushion is provided in the arc-shaped groove of the clamping member 207 and on the upper end of the pillow 208 to improve the patient's comfort during the examination.
[0029] Two pairs of limb restraint components 3 are arranged laterally on both sides of the base plate 1. The two pairs of limb restraint components 3 are responsible for fixing the upper torso and middle torso of the patient. The limb restraint components 3 include a first restraint belt 301 and a second restraint belt 302. The first ends of the first restraint belt 301 and the second restraint belt 302 are respectively fixed on both sides of the base plate 1. A clamp ring 303 is arranged on the second end of the first restraint belt 301. A pair of Velcro 304 is arranged on the second restraint belt 302. The second end of the second restraint belt 302 passes through the clamp ring 303 and is fixed by the Velcro 304. After the second restraint belt 302 passes through the clamp ring 303, the second restraint belt 302 can be tightened to fix the patient, so as to facilitate adaptation to patients of different body shapes.
[0030] Furthermore, an opening is provided on the side of the clasp 303, and the opening is small enough to facilitate manual removal of the second restraint belt 302 from the clasp 303 after the test is completed, while ensuring that the second restraint belt 302 will not be removed from the clasp 303 when the patient struggles;
[0031] Fixed U-shaped rods 4 are provided on both sides of the rear end of the base plate 1, and slidable second sliders 5 are provided on the two U-shaped rods 4. A third pair of limb restraint components 3 are provided between the two second sliders 5. The third pair of limb restraint components 3 are used to restrain and fix the patient's feet, and the first ends of the first restraint belt 301 and the second restraint belt 302 of the limb restraint components 3 are respectively fixed on the two second sliders 5. Due to the different heights of different patients, the movable third pair of limb restraint components 3 can adjust the position according to the patient's situation to improve practicality. A second screw hole is provided on the upper end of the second slider 5, and a second bolt 6 with a threaded connection is provided in the second screw hole. The front end of the second bolt 6 is movably in contact with the U-shaped rod 4. The second bolt 6 can fix the second slider 5 after the position of the third pair of limb restraint components 3 is determined, to ensure that the third pair of limb restraint components 3 will not move around during use to avoid affecting the fixing effect.
[0032] It should be emphasized that all components of this device are made of non-metallic materials to avoid affecting the examination results and causing danger to the patient's safety.
[0033] See also Figure 1-5 When in use, first pull one of the connecting rods 206 to separate the two clamping members 207, then the patient can lie on the bottom plate 1 and rest his head on the pillow 208, then push the connecting rod 206, driven by the first connecting rod 204 and the second connecting rod 205, the two clamping members 207 move simultaneously close to each other, when the clamping member 207 moves to contact with the patient's head, the connecting rod 206 is no longer pushed, then the first screw 209 is rotated, when the front end of the first screw 209 moves to contact with one of the first sliders 203, the two clamping members 207 are limited and cannot be separated, and the patient's head is fixed at this time;
[0034] Then, the second ends of the second straps 302 of the two pairs of fixed limb restraint components 3 are passed through the clamping ring 303 and slowly tightened until the first straps 301 and the second straps 302 restrain the patient's torso, and then fixed by Velcro 304. Then, according to the position of the patient's feet, the two second sliders 5 are moved to ensure that the first straps 301 and the second straps 302 of the third pair of limb restraint components 3 are flush with the patient's calf part, and then the second bolt 6 is rotated to ensure that the front end of the second bolt 6 is in contact with the U-shaped rod 4. At this time, the second slider 5 is fixed and remains motionless. Repeat the above operation, the first straps 301 and the second straps 302 fix the patient's legs. At this time, with the cooperation of the three pairs of limb restraint components 3 and the head fixing component 2, the patient's torso and head are fixed, and finally an MRI examination can be performed. The entire device can be adjusted according to the different body shapes of the patients, has a wide range of applications, and is convenient and quick to operate.
[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
