[0039] like Figures 1 to 9As shown, an embodiment of the present invention provides an augmented reality-based magnetic resonance examination auxiliary head-mounted equipment, including a frame 101, wherein AR glasses 102 are arranged in the frame 101, and connecting blocks 103 are fixedly connected to the left and right of the frame 101 symmetrically, and a strap 104 is fixedly connected between the two frames 101, and a first massage component and a second massage component for massaging the head are arranged in the connecting block 103, and an audio generating unit for noise reduction is arranged on the strap 104, and a first adjustment component for adjusting the audio generating unit and a storage component for storage are arranged on the audio generating unit, and a second adjustment component for adjusting the strap 104 is arranged on the strap 104.

[0040] When it is necessary to inspect the patient's magnetic resonance examination process, the AR glasses 102 are placed on the patient's eyes, and the length of the strap 104 is adjusted by the second adjustment component. The strap 104 is adjusted to a length suitable for the patient's head size, and the strap 104 is put on the surface of the patient's head. The frame 101 and the AR glasses 102 are restricted. The AR glasses 102 can make a virtual image appear in the patient's field of vision, and then, by adjusting the second adjustment component, the audio generating unit is adjusted to a position closer to the patient's ear. The audio generating unit simulates the ambient sound to eliminate the patient's nervousness. It should be noted that the audio generating unit is an existing mature technology and will not be described in detail here. The patient's head can be massaged by the first massage component and the second massage component to improve the patient's comfort during the examination.

[0041] like Figure 3 and Figure 4 As shown, the first massage component includes two fixing frames 201, and the two fixing frames 201 are respectively fixedly connected to one side of the corresponding connecting block 103, a motor 202 is arranged in the middle of the fixing frame 201, and the output end of the motor 202 is fixedly connected to a connecting shaft 203, and the connecting shaft 203 rotates and passes through one side of the connecting block 103, and a gear 204 is fixedly connected to one side of the connecting shaft 203, and a mounting groove 205 is opened in the middle of the connecting block 103, and a gear ring 206 is rotatably connected in the mounting groove 205, and the gear ring 206 is meshed with the gear 204, and four connecting rods 207 are fixedly connected to one side of the four connecting rods 207, and a plurality of balls 209 are arranged in a circle, and a sponge sheet 210 is fixedly connected to the mutually close sides of the two connecting blocks 103.

[0042] When the patient's head needs to be massaged, the motor 202 is started, and the output end of the motor 202 drives the connecting shaft 203 to rotate, the connecting shaft 203 drives the gear 204 to rotate, the gear 204 drives the gear ring 206 to rotate in the connecting block 103, the connecting block 103 drives the four connecting rods 207 to rotate at the same time, the connecting rod 207 drives the connecting rod 207 to rotate, and the annular plate 208 drives the multiple balls 209 to rotate on the sponge sheet 210. Since the sponge sheet 210 is in contact with the patient's head, when the multiple balls 209 are rotating, the multiple balls 209 can perform a circular massage on the patient's head, and the balls 209 can also play a protective role to prevent the balls 209 from directly contacting the patient's skin.

[0043] like Figure 5 As shown, the second massage component includes a first spring 211, the first spring 211 is fixedly connected to the inner wall of the mounting groove 205, one side of the first spring 211 is fixedly connected to a connecting column 212, one side of the connecting column 212 is fixedly connected to a massage block 213, the outer surface of the massage block 213 is fixedly connected to a connecting plate 214, the side of the connecting plate 214 away from the massage block 213 is fixedly connected to a triangular block 215, the side of the gear ring 206 close to the triangular block 215 is fixedly connected to a rectangular rod 216, and one end of the rectangular rod 216 is fixedly connected to a push block 217.

[0044] When it is necessary to massage the patient's head, the motor 202 is started, and the output end of the motor 202 drives the connecting shaft 203 to rotate, and the connecting shaft 203 drives the gear 204 to rotate, and the gear 204 drives the gear ring 206 to rotate. During the rotation, the gear ring 206 drives the rectangular rod 216 to rotate, and the rectangular rod 216 drives the push block 217 to rotate. When the push block 217 rotates to contact the inclined surface of the triangular block 215, the push block 217 can push the triangular block 215 and the connecting plate 214 to move, the first spring 211 is stretched, and the connecting plate 214 drives the connecting column 212 to impact and massage the patient's head. When the push block 217 completely leaves the triangular block 215, the first spring 211 rebounds, and the massage block 213 leaves the patient's head. When the gear ring 206 continues to rotate, the massage block 213 can continue to impact and massage the patient's head, which helps to relieve the patient's tension, stress and anxiety in cooperation with the first massage component.

[0045] like Figure 6As shown, the audio generating unit includes two rectangular blocks 218, and the two rectangular blocks 218 are both arranged on the strap 104. An L-shaped plate 219 is fixedly connected to the side of the two rectangular blocks 218 away from each other, and a fixed shaft 220 is fixedly connected between the inner side of the L-shaped plate 219 and the rectangular blocks 218. The outer surface of the fixed shaft 220 is rotatably connected to a long rod 221, and one end of the long rod 221 is fixedly connected to an earplug block 222, and the outer surface of the earplug block 222 is sleeved with an arc-shaped sponge 223.

[0046] When it is necessary to deal with the noise encountered by the patient during the examination, the long rod 221 is rotated to a vertical state, and the long rod 221 drives the earplug block 222 and the arc sponge 223, and the earplug block 222 and the arc sponge 223 are inserted into the patient's ear. By starting the earplug block 222, the earplug block 222 simulates the environmental sound and eliminates the patient's tension.

[0047] like Figure 7 As shown, the first adjustment component includes a fixing plate 224, the fixing plate 224 is fixedly connected to one side of the rectangular block 218, the rectangular block 218 is provided with a sliding groove 225, the sliding groove 225 penetrates the rectangular block 218, the strap 104 slides through the sliding groove 225, a fixing block 226 is fixedly connected to one side of the rectangular block 218, a moving groove 227 is provided in the middle of the fixing block 226, and the inner wall of the moving groove 227 is slidably connected to the sliding block 228 The sliding block 228 is fixedly connected to a pressure block 229 on one side close to the fixed plate 224, and the pressure block 229 slides through one end of the fixed block 226.

One side of the sliding block 228 is fixedly connected to a connecting rod 231, and the connecting rod 231 slides through the other end of the fixed block 226. The second spring 230 is sleeved on the outside of the connecting rod 231, and one side of the connecting rod 231 is fixedly connected to a pulling block 232.

[0048] When the audio generating unit needs to be adjusted, the pull block 232 is pulled, and the pull block 232 drives the connecting rod 231 to slide, and the connecting rod 231 drives the sliding block 228 to slide in the movable groove 227, and the second spring 230 is compressed, and the sliding block 228 drives the pressing block 229 to slide into the movable groove 227, and then, the rectangular block 218 is slid to make the rectangular block 218 slide on the strap 104, and the rectangular block 218 drives the long rod 221 and the earplug block 222 to slide. When the earplug block 222 is slid to a position suitable for inserting into the patient's ear, the pull block 232 is released, the second spring 230 rebounds, and the rectangular groove 238 drives the pressing block 229 to move toward the fixed plate 224. Under the action of the elastic force of the second spring 230, the pressing block 229 squeezes the strap 104 to restrict the rectangular block 218.

[0049] like Figure 8 As shown, the storage assembly includes a limit plate 233, which slides through the front end of the rectangular block 218. A storage groove 234 is provided on one side of the rectangular block 218. The front end of the limit plate 233 is fixedly connected to a rectangular plate 235, and a third spring 236 is fixedly connected between the rear end of the rectangular plate 235 and the rectangular block 218.

[0050] When the arc sponge 223 needs to be stored, the rectangular plate 235 is pulled, the third spring 236 is stretched, and the rectangular plate 235 drives the limiting plate 233 to slide on the rectangular block 218. When the limiting plate 233 slides to the inner wall of the storage groove 234, the long rod 221 is rotated, and the long rod 221 drives the earplug block 222 and the arc sponge 223. Then, the long rod 221 is rotated from a vertical state to a horizontal state, so that the limiting plate 233 is rotated into the storage groove 234, and the rectangular plate 235 is released. The third spring 236 rebounds, and the rectangular plate 235 drives the limiting plate 233 to slide into the storage groove 234 to limit the earplug block 222, so that the earplug block 222 can be stored when the device is restricted.

[0051] like Fig. 9 As shown, the second adjustment component includes a square block 237, and the square block 237 is arranged on the strap 104. A rectangular groove 238 is opened in the middle of the square block 237. The inner bottom wall of the rectangular groove 238 is rotatably connected with a rotating rod 239. The rotating rod 239 rotates and passes through the upper end of the square block 237. The strap 104 is wrapped around the outside of the rotating rod 239. The strap 104 slides through the square block 237, and a rotating component is arranged on the square block 237.

[0052] When the length of the strap 104 needs to be adjusted, the rotating rod 239 is rotated by the rotating assembly, and the rotating rod 239 drives the strap 104 to be retracted or released, so that the strap 104 can adapt to the different head sizes of different patients and improve the stability of the device and the patient's head.

[0053] like Fig. 9 As shown, the rotating assembly includes a rectangular sleeve 240, which is fixedly connected to the top of the square block 237, and the top of the rotating rod 239 is rotatably connected to the inner top wall of the rectangular sleeve 240.

One side of the worm 242 rotates and passes through one end of the rectangular sleeve 240. The worm 242 cooperates with the worm wheel 241, and the side of the worm 242 away from the rectangular sleeve 240 is fixedly connected to a knob 243.

[0054] When the rotating rod 239 needs to be rotated, the knob 243 is turned, and the knob 243 drives the worm 242 to rotate on the rectangular sleeve 240, the worm 242 drives the worm wheel 241 to rotate, and the worm wheel 241 drives the rotating rod 239 to rotate, and the rotating rod 239 drives the strap 104 to be reeled or released, so as to adjust the length of the strap 104.

[0055] like Figure 2 As shown, a soft pad 244 is symmetrically fixedly connected to the rear end of the frame 101, and the soft pad 244 is made of rubber material.

[0056] By providing the soft pad 244, when the patient uses the device, the soft pad 244 can protect the patient and prevent the frame 101 and the AR glasses 102 from directly contacting the patient's skin. The contact between the soft pad 244 and the patient's skin can also generate friction, making the device less likely to slide at will.

[0057] like Figure 3 and Figure 4 As shown, two T-shaped sliders 245 are fixedly connected to one side of the gear ring 206 , and the inner top wall of the connecting block 103 is provided with a T-shaped sliding groove 246 that cooperates with the two T-shaped sliders 245 .

[0058] By providing a T-shaped slider 245 and a T-shaped slot 246, when the gear ring 206 is rotating, the gear ring 206 can drive the T-shaped slider 245 to rotate in the T-shaped slot 246, and the T-shaped slot 246 can limit and guide the T-shaped slider 245 and the gear ring 206, thereby improving the stability of the gear ring 206 during rotation.

[0059] The workflow of the technical solution of the present invention is as follows:

[0060] When in use, place the AR glasses 102 in front of the patient's eyes and turn the knob 243. The knob 243 drives the worm 242 to rotate on the rectangular sleeve 240. The worm 242 drives the worm wheel 241 to rotate. The worm wheel 241 drives the rotating rod 239 to rotate. The rotating rod 239 drives the strap 104 to be reeled in or released. When the length of the strap 104 is adjusted to a length suitable for the size of the patient's head, the strap 104 is put on the surface of the patient's head. The frame 101, the AR glasses 102 and the patient's head are restricted by the strap 104.
