[0018] Beneficial effects

[0019] This invention provides an adjustable hollow frame head and face suspension support device for prone positioning. Compared with the prior art, it has the following advantages:

[0020] (1) The adjustable hollow frame prone head and face suspension support device, by setting two sets of spacing adjustment components in the device, allows the bidirectional screw to cooperate with two sets of movable seats and the first slide rod to adjust the spacing of the two sets of second slide rods, transmission components, movable blocks, first vernier, marker rod, first support ring, and second vernier, so that the spacing of the two sets of first support rings matches the spacing on both sides of the patient's forehead. Through the cross shaft, two sets of sleeves, bevel gear assembly, and first one-way screw, the two sets of movable blocks, the first vernier, and the first support ring are driven to move vertically and synchronously, so that the spacing and height of the two sets of second support rings are the same as those of the patient's cheeks. Without interfering with each other, the spacing and height of the support ends on both sides of the patient's head are synchronously adjusted, improving the efficiency of the device and increasing the adaptability of the support ends of the device to different patient head shapes.

[0021] (2) The adjustable hollow frame prone head and face suspension support device has a positioning component inside the device. When the rotating frame rotates, the positioning plate rotates with the rotating frame. When the rotating frame needs to be positioned, the screw is turned so that the positioning block driven by the screw is locked into the positioning groove corresponding to the positioning plate, thereby locking the rotating end of the rotating frame. In conjunction with the bracket, it prevents the rotating frame from shifting while ensuring the stability of the rotating frame during the subsequent patient face support process. Moreover, the rotation of the rotating frame plays a role in storing the support end of the device.

[0022] (3) The adjustable hollow frame prone head and face suspension support device has a storage component inside the device. After the L-shaped block, the two sets of first support rings and the second support ring are adjusted, the handwheel is turned to drive the storage wheel to rotate through the worm gear assembly, so that the protective belt fits the contour of the patient's head. The device provides support for the patient's face at adjacent intervals at the first support ring, the second support ring and the adjacent ends of the L-shaped block, which improves the support effect and makes it easy to make corresponding adjustments according to the patient's head shape.

A support component 52 for supporting the protective belt 57 is installed on the front side of the rotating frame 2.

[0036] The bidirectional screw 511 and the first slide bar 512 are both mounted on the rotating frame 2 along the X-axis. A first rotating wheel is fixedly connected to the left side of the bidirectional screw 511, and a second rotating wheel is fixedly connected to the left side of the cross shaft 519. A buffer pad is provided on the top of the bracket 4 and fits against the lower end of the rotating frame 2. The support member 52 includes a storage member 525 for storing two sets of protective straps 57. An L-shaped block 523 is connected to the front of the storage member 525. An L-shaped frame 522, which is slidably connected to the L-shaped block 523, is fixedly connected to the rotating frame 2. A second one-way screw 524 is rotatably connected to the moving frame 2 and threadedly connected to the L-shaped block 523. A drive block 521 is coaxially fixedly connected to the top of the second one-way screw 524. The transmission component 515 includes a sleeve 5151 rotatably connected to the movable seat 513 and slidably connected to the cross shaft 519.

[0037] A cross groove, slidably connected to the cross shaft 519, is provided through the sleeve 5151 from left to right. The sleeve 5151 is coaxially and fixedly connected to the driving bevel gear in the bevel gear assembly 5152. The driven bevel gear in the bevel gear assembly 5152 is coaxially and fixedly connected to the first one-way screw 5153. The driving bevel gear and the driven bevel gear in the bevel gear assembly 5152 mesh with each other. The support assembly 5 also includes a second vernier 55 fixedly connected to the front side of the movable seat 513. A scale 56 is fixedly connected to the lower side of the rotating frame 2 near the second vernier 55. The second vernier 55 cooperates with the scale 56 to display the position of the movable seat 513 along the X-axis. The first spacing adjustment component 51 also includes an indicator rod 518 fixedly connected to the lower side of the movable seat 513. A first vernier 517 is fixedly connected to the end of the movable block 516 near the indicator rod 518.

[0038] Both the first support ring 54 and the second support ring 58 are covered with a sponge sleeve with anti-slip texture. The inner side of the second support ring 58 has a movable groove that slides with the protective belt 57. The second spacing adjustment component 53 has the same internal structure as the first spacing adjustment component 51 and is used to adjust the spacing between the two sets of second support rings 58. The bidirectional screw 511 drives the two sets of movable seats 513 to slide relative to each other along the X-axis direction along the first slide rod 512, thereby driving the second slide rod 514, transmission component 515, movable block 516, first vernier 517, marker rod 518, first support ring 54, and second vernier 55 to adjust the spacing synchronously, so that the spacing between the two sets of first support rings 54 matches the spacing on both sides of the patient's forehead. The distance between the two sets of first support rings 54 is accurately read by the second vernier 55 and the scale 56. After the distance is adjusted, the second rotating wheel drives the cross shaft 519 to rotate. The rotating cross shaft 519 drives the two sets of movable blocks 516, the first vernier 517, and the first support ring 54 to move vertically and synchronously through the two sets of sleeves 5151, the bevel gear assembly 5152, and the first one-way screw 5153 respectively. The height of the first support ring 54 is read by the first vernier 517 and the marker rod 518.

[0039] The main difference between the second implementation method and the first implementation method is that:

[0040] The positioning component 3 includes a positioning disk 31 coaxially fixedly connected to the left side of the rotating end of the rotating frame 2. A screw 32 is threadedly connected to the mounting bracket 1 near the lower side of the positioning disk 31. A positioning block 33 is fixedly connected to the top of the screw 32. Several positioning grooves are provided on the side of the positioning disk 31 corresponding to the positioning block 33. The positioning block 33 engages with the positioning groove to lock the rotation angle of the rotating frame 2. The positioning grooves are evenly distributed along the axial direction of the positioning disk 31. When the rotating frame 2 rotates, the positioning disk 31 rotates with the rotating frame 2. When the rotating frame 2 needs to be positioned, the screw 32 is turned so that the screw 32 drives the positioning block 33 to engage in the positioning groove corresponding to the positioning disk 31, thereby locking the rotating end of the rotating frame 2. In conjunction with the bracket 4, it prevents the rotating frame 2 from shifting during subsequent patient facial support and ensures the stability of the rotating frame 2.

[0041] The main difference between the third and second implementation methods is that:

[0042] The storage component 525 includes a support block 5251 fixedly connected to the bottom of the L-shaped block 523. Two sets of connecting blocks 5252 are fixedly connected to the front side of the support block 5251. Two sets of storage wheels 5253 fixedly connected to the protective belt 57 are rotatably connected between the two sets of connecting blocks 5252. A worm gear assembly 5254 is connected to the top of the storage wheel 5253. A handwheel 5255 is connected to the left side of the two sets of worm gear assemblies 5254.

[0043] The lower side of the support block 5251 is provided with a sliding groove for the protective belt 57 to slide. The worm gear in the worm gear assembly 5254 is coaxially and fixedly connected to the handwheel 5255. The worm gear is rotatably connected to the connecting block 5252. The worm wheel in the worm gear assembly 5254 is coaxially and fixedly connected to the storage wheel 5253. The handwheel 5255 is provided with several positioning holes on its side. The left side of the connecting block 5252 is threaded with a positioning pin that matches the positioning hole and is used to lock the handwheel 5255. The two sets of worm gear assemblies 5254 are symmetrically arranged on both sides of the connecting block 5252. After the L-shaped block 523, the two sets of first support rings 54 and second support rings 58 are adjusted, the handwheel 5255 is rotated to drive the storage wheel 5253 to rotate through the worm gear assembly 5254, so that the protective belt 57 fits the contour of the patient's head. After the adjustment is completed, the positioning pin is screwed into the positioning hole of the handwheel 5255 to lock the length of the protective belt 57.

[0044] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0045] In use, the user installs the mounting bracket 1 of the device on the corresponding position of the medical bed. When it is necessary to provide suspended support for the patient's head and face, the bidirectional screw 511 is rotated through the first rotating wheel according to the patient's facial data. The bidirectional screw 511 drives the two sets of movable seats 513 to slide relative to each other along the X-axis direction along the first slide rod 512, thereby driving the second slide rod 514, transmission component 515, movable block 516, first vernier 517, marker rod 518, first support ring 54, and second vernier 55 to adjust their spacing synchronously, so that the spacing between the two sets of first support rings 54 matches the spacing on both sides of the patient's forehead. Among them, the second vernier 55, in conjunction with the scale 56, accurately reads the spacing between the two sets of first support rings 54. The spacing of the first support rings 54 is adjusted to match the spacing on both sides of the patient's forehead. During this process, the sleeve 5151 slides along the cross shaft 519. After the spacing is adjusted, the second rotating wheel drives the cross shaft 519 to rotate. The rotating cross shaft 519 drives the two sets of sleeves 5151, the bevel gear assembly 5152, and the first one-way screw 5153 to move the two sets of movable blocks 516, the first vernier 517, and the first support rings 54 vertically and synchronously. The first vernier 517 cooperates with the marker rod 518 to read the height of the first support rings 54. The spacing of the two sets of second support rings 58 is adjusted by the second spacing adjustment component 53. The two sets of second support rings 58 are spaced and at the same height as the patient's cheeks. Since the internal structure of the second spacing adjustment component 53 is the same as that of the first spacing adjustment component 51, its specific operating principle will not be described in detail. The drive block 521 drives the second one-way screw 524 to rotate, which in turn drives the L-shaped block 523 and the storage component 525 to move vertically. This allows the support block 5251 inside the storage component 525 to cooperate with the two sets of first support rings 54 and second support rings 58 to fit the patient's chin position. Then, turning the handwheel 5255 drives the storage wheel 5253 to rotate through the worm gear assembly 5254, thus extending and retracting the protective belt 57 so that the protective belt 57 fits snugly against the patient's head. After adjustment, screw the positioning pin into the positioning hole of the handwheel 5255 to lock the length of the protective belt 57. Rotate the rotating frame 2 and the support assembly 5 180 degrees. The rotating end of the rotating frame 2 drives the positioning plate 31 to rotate synchronously, so that the two sets of brackets on the rear side of the mounting frame 1 provide support for the rotating frame 2. Tighten the screw 32 so that the screw 32 drives the positioning block 33 to be engaged in the positioning groove corresponding to the positioning plate 31, thereby locking the rotating end of the rotating frame 2. Finally, let the patient lie face down and place their head on the support frame composed of the support block 5251, the two sets of first support rings 54, and the second support ring 58, so that the frame provides stable suspended support for the patient's head.
