[0027] To facilitate understanding of the technical solution of the present invention, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] Example 1, referring to Figures 1-5 This is the first embodiment of the present invention, which provides a prone head fixation bracket, including a head bracket and a support mechanism.

[0029] The head support includes a horizontal plate 1, on which a movable sleeve 8 is movably fitted. A first clamp is provided on the top of the movable sleeve 8. A concave plate 11 is fixed to the top of one end of the horizontal plate 1. An adjusting plate 111 is slidably connected inside the concave plate 11. A frame 12 is fixed to the top of the adjusting plate 111. A support plate 13 is fixed to the bottom of the frame 12. A first adjusting mechanism for adjusting height is provided on the support plate 13. Three lifting plates 44 are provided on the top of the support plate 13. A second adjusting mechanism for adjusting angle is provided on the lifting plates 44. A first adjusting plate 45 is installed on each of the three lifting plates 44 by hinges. Two of the first adjusting plates 45 are installed with a second adjusting plate 65 by hinges and are provided with a third adjusting mechanism. A third adjusting plate 66 is fixed to the top of the other first adjusting plate 45.

[0030] The support mechanism includes two first silicone airbags 35, a second silicone airbag 36, and an inflation box 34. The two first silicone airbags 35 are located on top of the two second adjusting plates 65, the second silicone airbags 36 are located on top of the third adjusting plate 66, and the inflation box 34 is fixed to one side of the frame 12.

[0031] In use, the head support is moved to the bedside and fixed to the crossbar of the bed using the first clamp. The front and rear positions of the support are adjusted by sliding the cross plate 1 within the movable sleeve 8. The height of the frame 12 is initially adjusted by sliding the adjustment plate 111 within the concave plate 11. The height of the three lifting plates 44 can be adjusted separately by the first adjustment mechanism, thereby adjusting the height of the support points. The angle of the first adjustment plate 45 can be adjusted by the second adjustment mechanism, and the angle of the second adjustment plate 65 can be adjusted by the third adjustment mechanism. This allows the first silicone airbag 35 and the second silicone airbag 36 installed on the top of the second adjustment plate 65 and the third adjustment plate 66 to adapt to different contours of the patient's face, providing multi-point, comfortable support. The support mechanism adjusts the firmness of the support by inflating and deflating the silicone airbags.

[0032] Specifically, the support mechanism also includes an air pump and three hoses 32. The air pump is fixed to the top of the inflation box 34, and the output port of the air pump is connected to the inflation box 34. The three hoses 32 are respectively fixed to the bottom of the two first silicone airbags 35 and the second silicone airbag 36 and are connected. Three first connecting pipes 33 are fixed to one side of the inflation box 34. A first valve is installed on the first connecting pipe 33. An internal threaded connector is fixed to one end of the first connecting pipe 33. An external threaded connector is fixed to one end of the hose 32. The external threaded connector is threadedly connected to the internal threaded connector. A first exhaust pipe is fixed to one side of the two first silicone airbags 35 and the second silicone airbag 36 and is connected. A second valve is installed on the first exhaust pipe.

[0033] When the silicone airbag needs to be inflated, open the first valve on the corresponding first connecting pipe 33 to start the air pump. The air pump will pump air into the inflation box 34, and then through the first connecting pipe 33 and the hose 32 into the designated silicone airbag to inflate it. After inflation is complete, close the first valve to maintain the air pressure. By setting three independent first valves, the inflation control of the three silicone airbags can be achieved individually. When deflation is required, open the second valve on the first exhaust pipe of the corresponding silicone airbag to release the internal air. The hose 32 is connected to the first connecting pipe 33 by a threaded joint for easy disassembly and maintenance.

[0034] Specifically, the first adjustment mechanism includes two fourth threaded rods 51 and a fifth threaded rod 54. The fifth threaded rod 54 is threadedly connected to the support plate 13. The two fourth threaded rods 51 are threadedly connected to both ends of the frame 12 and pass through the support plate 13 (the support plate 13 has through holes). The bottom of each of the three lifting plates 44 is fixed with a bearing. The two fourth threaded rods 51 and the fifth threaded rod 54 are fixed to the inner rings of the three bearings. The surface of the support plate 13 has two second circular holes. The inner walls of the two second circular holes are slidably connected with second guide rods 53. Both ends of the support plate 13 have two first circular holes. The inner walls of the two first circular holes are slidably connected with first guide rods 52. The top ends of the two first guide rods 52 and the top ends of the two sets of two second guide rods 53 are fixed to the bottom of the three lifting plates 44. Both ends of the frame 12 have two third circular holes. The first guide rods 52 are located in the third circular holes.

[0035] When the height of the two first silicone airbags 35 needs to be adjusted, the corresponding fourth threaded rod 51 is rotated. Since the fourth threaded rod 51 is threadedly connected to the frame 12 and fixed to the inner ring of the bearing at the bottom of the lifting plate 44, its rotation will drive the corresponding lifting plate 44, the first adjusting plate 45, the second adjusting plate 65 and the first silicone airbag 35 to move up and down as a whole. When adjusting the height of the second silicone airbag 36, the fifth threaded rod 54 is rotated. It is threadedly connected to the support plate 13. When it rotates, it will drive the lifting plate 44, the first adjusting plate 45, the third adjusting plate 66 and the second silicone airbag 36 connected to it to move up and down. During this process, the first guide rod 52 slides in the first round hole of the support plate 13 and the third round hole of the frame 12, and the second guide rod 53 slides in the second round hole of the support plate 13, which plays a key guiding and stabilizing role and prevents the lifting plate 44 from deflecting during the lifting process.

[0036] Specifically, the second adjustment mechanism includes three first fixing blocks 42, three second fixing blocks 43, and three third threaded rods 41. The three first fixing blocks 42 are respectively fixed to one side of the three lifting plates 44, the three second fixing blocks 43 are respectively fixed to one side of the three first adjusting plates 45, and the three third threaded rods 41 are respectively threadedly connected to the three first fixing blocks 42.

[0037] When it is necessary to adjust the angle of the first adjusting plate 45 and the components above it (the second adjusting plate 65 or the third adjusting plate 66), the third threaded rod 41, which is threadedly connected to the corresponding first fixed block 42, is rotated. The rotation of the third threaded rod 41 will cause its end to push the second fixed block 43 upward, thereby forcing the first adjusting plate 45 to rotate around the hinge between it and the lifting plate 44, thus achieving the adjustment of the angle.

[0038] Specifically, the third adjustment mechanism includes two small airbags 64 and two compression balls 61. The tops of the two first adjustment plates 45 are provided with grooves, and the two small airbags 64 are respectively fixed in the two grooves. One end of each of the two compression balls 61 is fixed with a second connecting pipe 63 and they are connected. One end of the second connecting pipe 63 is fixed with and connected to one side of the small airbag 64. A one-way valve is fixed to the bottom of the compression ball 61. A second exhaust pipe 62 is fixed with and connected to one side of the second connecting pipe 63. A third valve is installed on the second exhaust pipe 62.

[0039] When it is necessary to fine-tune the angle of the first silicone airbag 35 on the second adjusting plate 65, the corresponding compression ball 61 is repeatedly squeezed. When squeezed, air enters through the one-way valve at the bottom and is then forced into the small airbag 64 through the second connecting pipe 63, causing it to expand. The expansion of the small airbag 64 will push up the second adjusting plate 65, causing it to rotate relative to the first adjusting plate 45, thereby achieving angle adjustment. If it is necessary to reduce the angle, the third valve on the second exhaust pipe 62 can be opened to release the air in the small airbag 64. The compression ball 61 is preferably a latex inflatable ball.

[0040] The air pump is existing technology, and the working principle of this section is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0041] Example 2, refer to Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0042] Specifically, the top of the third adjustment plate 66 and the two second adjustment plates 65 are all fixed with hook and loop fasteners, and the bottom of the second silicone airbag 36 and the bottom of the two first silicone airbags 35 are all fixed with hook and loop fasteners, with the hook and loop fasteners adhering to each other.

[0043] The silicone airbag is connected to the adjustment plate via Velcro. When cleaning the silicone airbag is required, simply peel it off from the third adjustment plate 66 or the second adjustment plate 65. This simple operation greatly facilitates maintenance and hygiene.

[0044] Specifically, the first clamp includes a first U-shaped plate 22, a first clamping plate 23, and a first threaded rod 21. The first U-shaped plate 22 is fixed to the top of the movable sleeve 8. One side of the first clamping plate 23 is slidably connected to the inner wall of one side of the first U-shaped plate 22. The first threaded rod 21 is threadedly connected to the first U-shaped plate 22. A bearing 2 is fixed to the top of the first clamping plate 23. The bottom end of the first threaded rod 21 is fixed to the inner ring of the bearing 2.

[0045] When fixing the support, align the first clamp with the crossbar of the bed, so that the crossbar is housed in the first U-shaped plate 22, and then rotate the first threaded rod 21. The rotation of the first threaded rod 21 is converted into the linear downward movement of the first clamping plate 23 through the bearing 2 at the bottom, so that the inner walls of the first clamping plate 23 and the first U-shaped plate 22 together clamp the crossbar of the bed, thereby achieving reliable fixation of the entire head support.

[0046] Specifically, a second threaded rod 31 is threadedly connected to the concave plate 11, and multiple insertion holes (not shown in the figure) are opened on one side of the adjusting plate 111. One end of the second threaded rod 31 is inserted into the insertion hole.

[0047] When the initial height of the frame 12 needs to be adjusted, first rotate the second threaded rod 31 so that its end is disengaged from the current insertion hole of the adjusting plate 111. Then, pull the frame 12 up or down to make the adjusting plate 111 slide within the concave plate 11 to a suitable height. Next, align the insertion hole on the adjusting plate 111 corresponding to this height with the second threaded rod 31, and rotate the second threaded rod 31 again so that its end is inserted into the insertion hole. This will lock the relative position of the adjusting plate 111 and the concave plate 11, thereby fixing the height of the frame 12.

[0048] Specifically, both sides of the movable sleeve 8 are threadedly connected to a seventh threaded rod 81, and one end of the seventh threaded rod 81 abuts against the horizontal plate 1.

[0049] After adjusting the front and rear positions of the bracket by sliding the horizontal plate 1, tighten the seventh threaded rods 81 on both sides of the movable sleeve 8 so that their ends are tightly pressed against the horizontal plate 1. Use friction to prevent relative movement between the horizontal plate 1 and the movable sleeve 8, thereby locking the front and rear positions.

[0050] Specifically, bearings 3 are embedded in both ends of the frame 12. Movable rods 74 are fixed to the inner wall of the bearings 3. One end of each of the two movable rods 74 is fixedly connected to one side of the two support plates 121. A rubber ring 73 is movably sleeved on one of the movable rods 74. A cam-shaped hinge seat 72 is hinged to one end of the movable rod 74. A pressure plate 71 is fixed to one side of the hinge seat 72.

[0051] When the angle of the support plate 13 needs to be adjusted, lift the pressure plate 71 upwards by hand. The movement of the pressure plate 71 drives the cam-shaped hinge seat 72 to rotate. As the hinge seat 72 rotates, the protrusion of the hinge seat 72 will move away from the rubber ring 73, relieving the pressure on the rubber ring 73. At this time, rotate the support plate 13 by hand. The support plate 13 rotates through the movable rod 74 and the bearing. After rotating to the appropriate angle, bend the pressure plate 71 again to return the pressure plate 71 to its initial position. The protrusion of the hinge seat 72 will press the rubber ring 73, making the rubber ring 73 fit tightly against the frame 12, effectively limiting the angle of the support plate 13 and preventing free rotation.

[0052] When in use, take the head support to the side of the bed (the position of use), align the first clamp with the crossbar of the bed, so that the crossbar is inside the first U-shaped plate 22, rotate the first threaded rod 21, the first threaded rod 21 drives the first clamp 23 to move downward, so that the first clamp 23 and the first U-shaped plate 22 are in close contact with the crossbar of the bed, and fix the head support to the bed.

[0053] Then, adjust the whole to a suitable position, pull the horizontal plate 1, and slide the horizontal plate 1 in the movable sleeve 8. The movement of the horizontal plate 1 drives the movement of multiple components such as the concave plate 11, the frame 12, the first silicone airbag 35 and the second silicone airbag 36 to adjust the front and back positions. Adjust to a suitable position, rotate the seventh threaded rod 81 so that one end of the seventh threaded rod 81 is in close contact with the horizontal plate 1 to fix the position.

[0054] When it is necessary to adjust the height of the frame 12, rotate the second threaded rod 31 to move the second threaded rod 31 away from the current insertion hole, pull the frame 12 upward to the appropriate height, and align the insertion hole with the second threaded rod 31. Rotate the second threaded rod 31 again to insert one end of the second threaded rod 31 into the corresponding insertion hole to fix the height of the frame 12.

[0055] When the height of the first silicone airbag 35 needs to be adjusted, the fourth threaded rod 51 is rotated. The rotation of the fourth threaded rod 51 drives the movement of the lifting plate 44, the first adjusting plate 45, the second adjusting plate 65 and the first silicone airbag 35, so that the first silicone airbag 35 is in a suitable height position. During the adjustment process, the first guide rod 52 slides in the first round hole and the third round hole, which plays a guiding and stabilizing role.

[0056] When it is necessary to adjust the height of the second silicone airbag 36, rotate the fifth threaded rod 54. Since the fifth threaded rod 54 is threadedly connected to the support plate 13, as it rotates, it will drive the lifting plate 44, the first adjusting plate 45, the third adjusting plate 66 and the second silicone airbag 36 to move, so that the second silicone airbag 36 is in a suitable height position. During the adjustment process, the second guide rod 53 slides in the second round hole, which plays a guiding and stabilizing role.

[0057] When it is necessary to adjust the angle of the second silicone airbag 36 or the first silicone airbag 35, rotate the third threaded rod 41 that is threadedly connected to the first fixed block 42. The rotation of the third threaded rod 41 will push the second fixed block 43 upward, thereby changing the angle of the first adjusting plate 45 relative to the lifting plate 44.

[0058] When it is necessary to adjust the angle of the first silicone airbag 35 on the second adjusting plate 65, squeeze the squeezing ball 61. Air enters through one-way valve one, and then through one-way valve two and the second connecting pipe 63 into the small airbag 64, causing the small airbag 64 to inflate and push the second adjusting plate 65 to rotate relative to the first adjusting plate 45, thereby achieving angle adjustment. If it is necessary to release air for adjustment, the third valve on the second exhaust pipe 62 can be opened to release the air in the small airbag 64.

[0059] Open the first valve on the first connecting pipe 33 on one side of the air box 34, start the air pump fixed on the top of the air box 34, the air pump delivers air into the air box 34, and then through the hose 32 into the two first silicone air bags 35 and the second silicone air bag 36 respectively, so that the silicone air bags inflate to a suitable degree to provide comfortable facial support. After inflation is complete, close the first valve. If deflation is required, open the second valve on the first exhaust pipe to release the air in the silicone air bag. Since there are three first valves, one of the silicone air bags can be inflated individually.

[0060] Because the silicone airbag is fixed by the hook and loop sides of the Velcro, it is easy to disassemble and clean.

[0061] When the angle of the support plate 13 needs to be adjusted, lift the pressure plate 71 upwards by hand. The movement of the pressure plate 71 drives the cam-shaped hinge seat 72 to rotate. As the hinge seat 72 rotates, the protrusion of the hinge seat 72 will move away from the rubber ring 73, relieving the pressure on the rubber ring 73. At this time, rotate the support plate 13 by hand. The support plate 13 rotates through the movable rod 74 and the bearing. After rotating to the appropriate angle, bend the pressure plate 71 again to return the pressure plate 71 to its initial position. The protrusion of the hinge seat 72 will press the rubber ring 73, making the rubber ring 73 fit tightly against the frame 12, effectively limiting the angle of the support plate 13 and preventing free rotation.

[0062] The threads of multiple threaded rods are single-start threads (the thread helix angle is less than or equal to the equivalent friction angle, and they have self-locking properties). The material specifications of multiple threaded rods can be selected according to actual needs.

[0063] It should be noted that the air pump needs to be controlled by an external controller (such as a PLC controller) and powered by an external power source (such as mains power) when in use.

[0064] Among them, the squeeze ball 61 is a latex inflatable ball (i.e., the inflatable ball commonly used to measure blood pressure).

[0065] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention shall be determined by the scope defined in the claims. Any improvements and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall also be considered as within the scope of protection of the present invention.
