Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary appliances, and particularly to a head support device. Background Art

[0002] The head support device plays a crucial role in magnetic resonance imaging (MRI) examinations in the radiology department. It is usually made of soft and ergonomic materials, which can conform to the head shapes of different patients and effectively reduce the discomfort caused by maintaining a fixed posture for a long time.

[0003] After retrieval, a Chinese invention patent with the patent number CN116942132A discloses a head support device. Compared with the prior art, on one side of the MRI brain tumor and other disease detector of the Chinese invention patent with the patent number CN116942132A, there is a fixed installation block. On the top surface of the installation block, there is a first sliding groove. On the inner wall surface of the first sliding groove, there is a moving plate. On the top surface of the moving plate, there is a fixed installation support block; a support assembly, which is arranged above the moving plate and is used to support the patient's head. The patient's head can be supported and fixed by the support block, avoiding the deviation of the detection data of brain tumors and other diseases caused by the shaking of the head during the detection of brain tumors and other diseases. The patient's neck can be limited and supported by the installation column. When the patient's head is placed on the top surface of the support block, the neck will exert pressure on the installation column through the rubber pad, so that the installation column moves downward under the action of the spring to support the patient's neck.

[0004] However, in the actual use process of the above device, although it can fix the head, the effect is relatively single. When the MRI equipment is running, it will generate relatively large noise and flashing lights. This kind of noise and light interference may make people feel uncomfortable and anxious, thus causing the patient to move around. However, the above device does not solve such problems well. Although special earplugs or earmuffs are provided for patients to use before the detection, each patient wearing earplugs or earmuffs by themselves will significantly increase the overall inspection time. For those patients with inconvenient hands and feet, they often need the staff to spend extra time and energy to assist in wearing. Therefore, a head support device is proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of relatively single effect and the need for patients to wear eye masks and earmuffs alone in the prior art, and to propose a head support device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A head support device, including a nuclear magnetic resonance device, an upper part of the nuclear magnetic resonance device is fixedly connected with a box body, an upper part of the box body is movably connected with a headrest plate, a support assembly is arranged on the box body, the support assembly includes a first connecting rod and a push rod symmetrically and movably connected to the outside of the box body, and a support plate and ear cups symmetrically and movably connected to the upper part of the box body. The headrest plate passes through the headrest of the head, and the weight of the head drives the headrest plate to press down. As the headrest plate presses down, the push rod drives the two first connecting rods to contract inwards and towards each other. The two first connecting rods drive the support plate and ear cups to support and protect both sides of the head and the ears resting on the headrest plate.

[0008] An auxiliary assembly is arranged on the box body. The auxiliary assembly includes first gears symmetrically and movably connected to the inside of the box body, and ropes and eye masks symmetrically and movably connected to the outside of the box body. As the headrest plate presses down, the push rod drives the rotation of the two first gears. The rotation of the first gears winds the ropes, and the winding of the ropes tightens the two eye masks placed on the eyes.

[0009] The above technical solution further includes:

[0010] A plurality of threaded grooves are formed on the outside of the box body. A threaded rod is movably connected to the outside of the box body. The threaded rod is in threaded connection with the threaded grooves, and the threaded rod is in threaded connection with the headrest plate. By rotating the threaded rod and connecting it with the threaded grooves, the headrest plate is restricted.

[0011] Convex grooves are symmetrically formed on the side surface of the box body. The box body is slidably connected with the convex grooves. The opening of the convex grooves is adapted to the size of the headrest plate, and the cross-sections of the headrest plate and the convex grooves are both convex. The convex shapes at both ends of the headrest plate fit the convex shapes of the convex grooves, improving the stability of the headrest plate during movement.

[0012] A first spring is fixedly connected to a side of the headrest plate close to the box body. One end of the first spring away from the headrest plate is fixedly connected to the box body. The number of the first springs is multiple groups, and the multiple groups of first springs are symmetrically and evenly distributed along the four corners of the headrest plate. The even distribution of the first springs enables the headrest plate to have a buffer and smooth movement when being pressurized by the weight of the head.

[0013] The headrest plate is fixedly connected to the push rod on a side close to the box body. A fixed plate is fixedly connected to the inside of the box body. A fixed rod is fixedly connected to a side of the fixed plate close to the headrest plate. The second gear slides with the fixed rod as the headrest plate moves downwards.

[0014] A movable plate is slidably connected to the outside of the fixed rod. The movable plate is movably connected to the first connecting rod. A fourth spring is fixedly connected to one side of the fixed plate close to the headrest plate. One end of the fourth spring away from the fixed plate is fixedly connected to the movable plate. The push rod is movably connected to the fixed rod. A fifth spring is fixedly connected to the outside of the first connecting rod. The fifth spring and the fourth spring respectively pull and push the first connecting rod to make the first connecting rod return to the origin.

[0015] The end of the first connecting rod is movably connected to a second connecting rod. The second connecting rod slides inside the limit ring as the first connecting rod moves. The upper part of the box body is symmetrically and fixedly connected with limit rings. The second connecting rod is movably connected to the limit rings. One end of the second connecting rod away from the first connecting rod is movably connected to a cylindrical ring.

[0016] A second spring is fixedly connected to one side of the limit ring close to the cylindrical ring. One end of the second spring away from the limit ring is fixedly connected to the cylindrical ring. One end of the cylindrical ring away from the second connecting rod is fixedly connected to a support plate. The support plate is movably connected to the earphone cup. A plurality of earphone cups are fixedly connected to the inside of the support plate. One end of the earphone cup away from the support plate is fixedly connected to the earphone cup. The second spring buffers the head support restriction of the support plate.

[0017] A ring-shaped rack is fixedly connected to the outside of the push rod. Two second gears are symmetrically and rotatably connected to the inside of the nuclear magnetic resonance device. Both of the two second gears are meshed with the ring-shaped rack. The second gear is meshed with the first gear. The first gear is movably connected to a rope. The downward movement of the ring-shaped rack drives the second gear and the first gear to rotate.

[0018] One end of the rope away from the first gear is fixedly connected to an elastic band. One side of the elastic band away from the rope is fixedly connected to an eye mask. One side of the eye mask away from the elastic band is fixedly connected to a magic tape. The rotation of the first gear winds the rope to tighten the eye mask.

[0019] The present invention has the following beneficial effects:

[0020] 1. In the present invention, through the headrest plate in the support assembly for the head, the weight of the head drives the headrest plate to press down. The push rod drives the two first connecting rods to contract inwards and towards each other as the headrest plate presses down. The two first connecting rods drive the support plate and the earphone cups to support and protect both sides of the head and the ears of the head resting on the headrest plate, effectively preventing the unconscious movement of the head during the examination and the anxiety caused by the noise of the machine to the patient. Moreover, for patients with inconvenient hands and feet, they can easily wear it without the assistance of additional personnel, greatly saving the examination time and improving the overall efficiency.

[0021] 2. In the present invention, as the push rod in the auxiliary component drives the rotation of the two first gears when the headrest plate is pressed down, the rotation of the first gears winds the rope, and the winding of the rope tightens the two eye masks placed on the eyes. This adaptive eye mask can quickly and tightly fit the eyes, effectively isolating external light and interference. The automatically tightened eye mask can also play a role in fixing the head to a certain extent, helping the patient maintain a stable examination posture, thereby contributing to improving the quality and efficiency of imaging examinations. Moreover, the patient does not need to wear the eye mask by themselves, and only the staff needs to connect the two eye masks. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] As Figures 1-7 shown, a head support device proposed by the present invention includes a nuclear magnetic resonance device 1. A box body 2 is fixedly connected to the upper part of the nuclear magnetic resonance device 1. A headrest plate 3 is movably connected to the upper part of the box body 2. A support assembly is arranged on the box body 2. The support assembly includes a first connecting rod 4 and a push rod 20 symmetrically and movably connected to the outside of the box body 2, and a support plate 10 and ear cups 11 symmetrically and movably connected to the upper part of the box body 2. The headrest plate 3 passes through the headrest of the head, and the weight of the head drives the headrest plate 3 to press down. As the headrest plate 3 presses down, the push rod 20 drives the two first connecting rods 4 to contract inwardly and oppositely. The two first connecting rods 4 drive the support plate 10 and the ear cups 11 to support and protect the two sides of the head and the ears resting on the headrest plate 3.

[0033] An auxiliary assembly is arranged on the box body 2. The auxiliary assembly includes first gears 22 symmetrically and movably connected to the inside of the box body 2, and ropes 12 and eye masks 14 symmetrically and movably connected to the outside of the box body 2. As the headrest plate 3 presses down, the push rod 20 drives the rotation of the two first gears 22. The rotation of the first gears 22 winds the ropes 12, and the winding of the ropes 12 tightens the two eye masks 14 placed on the eyes.

[0034] A plurality of threaded grooves 17 are formed on the outside of the box body 2. A threaded rod 16 is movably connected to the outside of the box body 2. The threaded rod 16 is threadedly connected to the threaded grooves 17, and the threaded rod 16 is threadedly connected to the headrest plate 3. By rotating the threaded rod 16 and connecting it to the threaded grooves 17, the headrest plate 3 is restricted.

[0035] Convex grooves 18 are symmetrically formed on the side surface of the box body 2. The box body 2 is slidably connected to the convex grooves 18. The opening of the convex grooves 18 is adapted to the size of the headrest plate 3, and the cross-sections of the headrest plate 3 and the convex grooves 18 are both convex. The convex shapes at both ends of the headrest plate 3 fit the convex shapes of the convex grooves 18, improving the stability of the headrest plate 3 during movement.

[0036] One side of the headrest plate 3 close to the box body 2 is fixedly connected with a first spring 5. One end of the first spring 5 far from the headrest plate 3 is fixedly connected to the box body 2. The number of the first springs 5 is multiple groups, and the multiple groups of first springs 5 are symmetrically and evenly distributed along the four corners of the headrest plate 3. The uniform distribution of the first springs 5 enables the headrest plate 3 to have a buffer and smooth movement when being pressurized by the weight of the head.

[0037] One side of the headrest plate 3 close to the box body 2 is fixedly connected with a push rod 20. A fixed plate 26 is fixedly connected inside the box body 2. One side of the fixed plate 26 close to the headrest plate 3 is fixedly connected with a fixed rod 25. The second gear 23 slides with the movement of the headrest plate 3 downwards and the fixed rod 25.

[0038] An activity plate 24 is slidably connected to the outside of the fixed rod 25. The activity plate 24 is movably connected with the first connecting rod 4. One side of the fixed plate 26 close to the headrest plate 3 is fixedly connected with a fourth spring 27. One end of the fourth spring 27 far from the fixed plate 26 is fixedly connected to the activity plate 24. The push rod 20 is movably connected with the fixed rod 25. A fifth spring 28 is fixedly connected to the outside of the first connecting rod 4. The fifth spring 28 and the fourth spring 27 respectively pull and push the first connecting rod 4 to make the first connecting rod 4 return to the origin.

[0039] The end of the first connecting rod 4 is movably connected with a second connecting rod 6. The second connecting rod 6 slides inside the limiting ring 7 with the movement of the first connecting rod 4. The limiting rings 7 are symmetrically and fixedly connected to the upper part of the box body 2. The second connecting rod 6 is movably connected with the limiting ring 7. One end of the second connecting rod 6 far from the first connecting rod 4 is movably connected with a cylindrical ring 9.

[0040] One side of the limiting ring 7 close to the cylindrical ring 9 is fixedly connected with a second spring 8. One end of the second spring 8 far from the limiting ring 7 is fixedly connected to the cylindrical ring 9. One end of the cylindrical ring 9 far from the second connecting rod 6 is fixedly connected with a support plate 10. The support plate 10 is movably connected with the earphone cup 11. A plurality of earphone cups 11 are fixedly connected inside the support plate 10. One end of the earphone cup 11 far from the support plate 10 is fixedly connected to the earphone cup 11. The second spring 8 buffers the head support restriction of the support plate 10.

[0041] In this embodiment, first, it should be described that the overall structure of this device is made of plastic and other non-metallic materials, which does not affect nuclear magnetic resonance detection. By rotating the threaded rod 16 through the threaded groove 17, the headrest plate 3 is limited, so that the patient's head lies on the upper part of the headrest plate 3 and the headrest plate 3 will not move. A soft pad is arranged above the headrest plate 3 to improve the comfort of the patient. When the patient lies down, rotate the threaded rod 16 to make the threaded rod 16 away from the headrest plate 3, releasing the restriction on the headrest plate 3. At this time, with the weight of the patient's head, the headrest plate 3 slowly descends through the first spring 5. During the descending process, the push rod 20 is pushed to move. The downward movement of the push rod 20 pushes the movable plate 24 on the fixed rod 25 to move downward. The downward movement of the movable plate 24 drives the two first connecting rods 4 connected to it to move towards each other on the outside of the box body 2. The opposite movement of the first connecting rods 4 drives the second connecting rods 6 at the ends to move oppositely inside the limiting ring 7. The movement of the second connecting rods 6 drives the support plate 10 and the earphones 11 at the end of the cylindrical ring 9 to support and limit the two sides of the head and block and protect the two ears;

[0042] Pressed by the two sides of the head, the second connecting rod 6 moves inside the cylindrical ring 9 through the buffering of the second spring 8, so that the support and limitation of the support plate 10 on the two sides of the head are more fitting and comfortable. And a soft pad is arranged on the side of the support plate 10 to improve the comfort of the patient. Moreover, the third spring 19 inside the support plate 10 supports the earphones 11, so that the earphones 11 have a better wrapping effect on the ears on both sides of the head and the comfort is improved. When the patient gets used to it, rotate the threaded rod 16 to the position of the threaded groove 17 corresponding to the descent of the headrest plate 3, so that the rotation of the threaded rod 16 restricts the headrest plate 3 through the threaded groove 17, preventing the headrest plate 3 from moving due to the patient's random movement. When the patient finishes the detection and the restriction of the threaded rod 16 on the headrest plate 3 is released, at this time the head slowly rises, and the headrest plate 3 returns to the original point through the rebound of the first spring 5. The first connecting rod 4 drives the support plate 10 and the earphones 11 to return to the original point through the rebound of the fourth spring 27 and the contraction of the fifth spring 28.

[0043] Embodiment Two

[0044] As Figures 1-7 shown, based on Embodiment One, a ring gear 21 is fixedly connected to the outside of the push rod 20. Two second gears 23 are symmetrically and rotatably connected inside the nuclear magnetic resonance device 1. The two second gears 23 are meshed with the ring gear 21. The second gear 23 is meshed with the first gear 22. The first gear 22 is movably connected to the rope 12. The downward movement of the ring gear 21 drives the second gear 23 and the first gear 22 to rotate.

[0045] One end of the rope 12 far away from the first gear 22 is fixedly connected with an elastic band 13. The elastic band 13 is fixedly connected to the blindfold 14 on the side far away from the rope 12. The blindfold 14 is fixedly connected with a magic tape 15 on the side far away from the elastic band 13. The rotation of the first gear 22 winds the rope 12 to tighten the blindfold 14.

[0046] In this embodiment, through the above description, when the headrest plate 3 is fixed in the original position by the threaded rod 16, the patient's head is placed above the headrest plate 3. At this time, the blindfold 14 is connected by the magic tape 15. By adjusting the magic tape 15, the blindfold 14 is fixed at a suitable tightening degree for the patient's eyes. Then, the rope 12 is moved to the back of the ears to prevent it from affecting the protection of the ears by the earcups 11. At this time, the restriction of the threaded rod 16 on the headrest plate 3 is released, and the headrest plate 3 is driven to move downward by the own weight of the head. The annular rack 21 on the push rod 20 follows the downward movement. The downward movement of the annular rack 21 drives the rotation of the second gear 23, and the rotation of the second gear 23 drives the rotation of the first gear 22;

[0047] The rotation of the first gear 22 winds the rope 12. The wound rope 12 pulls the elastic band 13 to tighten the blindfold 14, making the blindfold 14 fit the eyes more closely and playing a supporting role for the passage. Soft pads are wrapped on the outer sides of the rope 12 and the elastic band 13 to prevent discomfort to the patient during the tightening process. When the detection is completed, by releasing the connection of the two magic tapes 15 and slowly raising the head, the headrest plate 3 slowly rises due to the rebound of the first spring 5. The annular rack 21 on the push rod 20 follows the slow rise of the headrest plate 3, so that the annular rack 21 drives the second gear 23 to rotate. The rotation of the second gear 23 drives the rotation of the first gear 22, and the rotation of the first gear 22 releases the tightened state of the wound rope 12 during the rotation process.

[0048] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
