[0023] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] like Figure 1 As shown, the inner upper surface of the headrest portion 2 is provided with a breathable net 6;

[0026] The breathable net 6 can reduce the humidity of the skin of the headrest 2 and reduce the environment for bacterial growth. For patients who are bedridden for a long time, the occurrence of pressure sores can be effectively prevented.

[0027] like Figure 1 As shown, an improved posterior cranial fossa decompression pillow for long-term bedridden patients is provided, comprising a pillow body 1, a headrest portion 2 is integrally formed on the upper surface of the pillow body 1, a neckrest portion 3 is integrally formed in front of the headrest portion 2, an adjustment mechanism 4 is arranged on the left side of the upper surface of the pillow body 1, and a pressing mechanism 5 is arranged on the inner side wall of the neckrest portion 3;

[0028] The patient gently places his head on the headrest 2. The shape and material of the headrest 2 can provide appropriate support and decompression for the patient's posterior cranial fossa. At the same time, the patient's neck is naturally placed on the cervical pillow 3. The design of the cervical pillow 3 can fit the physiological curve of the patient's neck, provide stable support for the neck, and reduce the pressure on the neck. During use, the patient can adjust the height of the cervical pillow 3 through the adjustment mechanism 4 to achieve the most comfortable angle. At the same time, the patient's neck can be pressed through the set pressing mechanism 5 to promote relaxation of the neck muscles and blood circulation, and relieve neck pain and stiffness.

[0029] like Figure 1 As shown, the inner wall of the headrest portion 2 and the inner wall of the neckrest portion 3 are both provided with a cushion 7;

[0030] The soft cushion 7 can reduce the friction between the head and neck and the inner wall of the pillow, thereby effectively protecting the patient's head and neck.

[0031] like Figure 2 and Figure 3 As shown, the pressing mechanism 5 includes a semicircular block 501, and a plurality of protruding circular holes 502 are integrally formed on the upper surface of the semicircular block 501. A plurality of rotating rods 503 are arranged inside the semicircular block 501. A control motor 504 is fixedly connected to the center of the lower surface of the semicircular block 501. The bottom ends of the plurality of rotating rods 503 are respectively rotatably connected to the inner lower surface of the semicircular block 501 through a rotating shaft and are fixedly connected to the top of the output shaft of the control motor 504. The outer side walls of the plurality of rotating rods 503 are fixedly connected to a plurality of gears 505. The outer side walls of the plurality of gears 505 are respectively meshed with each other. The plurality of rotating rods 503 are connected together, the inner upper surfaces of the plurality of rotating rods 503 are integrally formed with a sliding cavity 506, the interiors of the plurality of sliding cavities 506 are slidably connected with T-shaped sliders 507, the top ends of the plurality of T-shaped sliders 507 extend to the interiors of the plurality of protruding circular holes 502 respectively, and are all fixedly connected with massage balls 508, the outer side walls of the plurality of T-shaped sliders 507 are integrally formed with annular grooves 509, the inner left sides of the plurality of protruding circular holes 502 are fixedly connected with limiting blocks 510, and the right ends of the plurality of limiting blocks 510 are respectively slidably connected with the plurality of annular grooves 509;

[0032] When in use, the control motor 504 is started to drive the rotating rod 503 fixedly connected thereto to rotate. Since the gears 505 fixedly connected to the outer walls of the plurality of rotating rods 503 are meshed with each other, when one rotating rod 503 rotates, it will drive the other rotating rods 503 to rotate synchronously. The rotation of the plurality of rotating rods 503 simultaneously drives the plurality of T-shaped sliders 507 to rotate, so that through the sliding limit of the plurality of limit blocks 510 and the plurality of annular grooves 509, the plurality of T-shaped sliders 507 can be repeatedly moved up and down, and the plurality of massage balls 508 can be repeatedly extended to the outside of the plurality of protruding circular holes 502 through the plurality of T-shaped sliders 507, and the patient's neck can be repeatedly knocked by the plurality of massage balls 508, thereby promoting blood circulation in the neck and relieving neck muscle tension and pain. When the pressing mechanism 5 is closed, the plurality of control motors 504 can be used to control the plurality of massage balls 508 to be retracted into the plurality of protruding circular holes 502, and the semicircular block 501 can be used to effectively support the patient's neck.

[0033] like Figure 1 As shown, a control switch 8 is provided on the right side of the pillow body 1;

[0034] The control switch 8 provided can be used to start and stop the pressing mechanism 5, and the patient can turn on or off the neck pressing function at any time according to his or her own feelings, thereby avoiding excessive massage or unnecessary interference when massage is not needed.

[0035] like Figure 2 As shown, the adjustment mechanism 4 includes a support plate 401, the upper surface of the support plate 401 is fixedly connected to the lower surface of the semicircular block 501, a control cavity 402 is integrally formed in the front of the interior of the pillow body 1, a fixed circular groove 403 is opened on the left side of the upper surface of the pillow body 1, a control handle 404 is arranged inside the fixed circular groove 403, and a screw rod 405 is symmetrically connected to the lower surface of the control cavity 402 through a rotating shaft, the top of the screw rod 405 located on the left side of the control cavity 402 is fixedly connected to the center of the lower surface of the control handle 404, and the top of the screw rod 405 located on the right side of the control cavity 402 is fixedly connected to the center of the lower surface of the control handle 404. The top end of the screw rod 405 is rotatably connected to the inner upper surface of the control cavity 402 via a rotating shaft, and an adjustment vertical slot 406 is provided between the left side and the right side of the inner wall of the cervical occipital portion 3 and the control cavity 402. The outer side walls of the two screw rods 405 are threadedly connected with a sliding plate 1 407, and the opposite sides of the two sliding plates 1 407 pass through two adjustment vertical slots 406 respectively, and are fixedly connected to the left and right sides of the support plate 401 respectively, and the lower side walls of the two screw rods 405 are fixedly connected with a rotating disk 408, and the outer side walls of the two rotating disks 408 are jointly connected with a transmission belt 409;

[0036] When the height of the cervical pillow portion 3 needs to be adjusted, the control handle 404 is rotated to drive the screw rod 405 on the left to rotate, and the two turntables 408 and the transmission belt 409 can drive the two screw rods 405 to rotate simultaneously. As the two screw rods 405 rotate, the sliding plate 407 threadedly connected to the outer wall thereof moves up and down on the screw rod 405. When the sliding plate 407 moves upward, the supporting plate 401 and the semicircular block 501 are pushed up as a whole, thereby increasing the height of the cervical pillow portion 3. When the sliding plate 407 moves downward, the height of the cervical pillow portion 3 is reduced. The user can adjust the height of the cervical pillow portion 3 at any time according to the patient's needs and comfort to achieve the best treatment effect.

[0037] like Figure 2 As shown, the inner upper surface and the inner lower surface of the two adjusting vertical grooves 406 are both fixedly connected with a guide rod 410, and the outer side walls of the two guide rods 410 are respectively slidably connected with the two sliding plates 407;

[0038] The two guide rods 410 are provided to ensure the verticality of the two sliding plates 407 during the up and down movement, so that the neck pillow part 3 always maintains a horizontal state, providing stable support for the patient.

[0039] like Figure 3As shown, the left side and the right side of the outer wall of the control handle 404 are fixedly connected with a fixed block 411, the interior of the two fixed blocks 411 is integrally formed with a sliding cavity 412, the inner upper surfaces of the two sliding cavities 412 are provided with a through-type sliding transverse groove 413, the interior of the two sliding cavities 412 is slidably connected with a sliding plate 414, the upper surfaces of the two sliding plates 414 are fixedly connected with a toggle plate 415, the upper surfaces of the two toggle plates 415 respectively penetrate two more sliding transverse grooves 413, the opposite sides of the two sliding plates 414 are respectively fixedly connected to the interior of the two sliding cavities 412 with two springs 416, the inner side wall of the fixed circular groove 403 is provided with a plurality of positioning holes 417, the opposite sides of the two sliding plates 414 are fixedly connected with a plug rod 418, and the opposite ends of the two plug rods 418 extend to the inside of the positioning hole 417 on the left and the positioning hole 417 on the right respectively;

[0040] When the neck pillow 3 is not adjusted, the control handle 404 is in a fixed state. At this time, the two sliding plates 414 are squeezed to both sides under the action of the spring 416, so that the plug rod 418 is inserted into the positioning hole 417, thereby fixing the control handle 404 in the current position. When the height of the neck pillow 3 needs to be adjusted, the user uses his fingers to simultaneously push the two toggle plates 415 toward the middle, and the two toggle plates 415 slide in the two sliding transverse grooves 413, driving the two sliding plates 414 to move toward the middle in the two sliding cavities 412 to overcome the elastic force of the spring 416, so that the two plug rods 418 can be inserted from the two positioning holes 417. Pull it out to release the fixation of the control handle 404. At this time, the height of the semicircular block 501 can be adjusted by rotating the control handle 404. When it is adjusted to a suitable height, the user releases the two toggle plates 415. Under the elastic force of the spring 416, the two sliding plates 414 move to both sides, driving the two plug-in rods 418 to be reinserted into the corresponding two positioning holes 417, so that the control handle 404 can be fixed again, and the height of the neck pillow 3 is also fixed at the current position, thereby preventing the control handle 404 from rotating due to accidental touch, avoiding unnecessary changes in the height of the neck pillow 3, and improving the stability and safety of the product.

[0041] like Figure 3 As shown, the inner left side and the inner right side of the two sliding transverse grooves 413 are both fixedly connected with the second guide rod 419, and the outer side walls of the two second guide rods 419 are respectively slidably connected with the two toggle plates 415;

[0042] When the user moves the two toggle plates 415, the two toggle plates 415 can only slide in the two sliding transverse grooves 413 along the axial direction of the two guide rods 419, thereby preventing the two toggle plates 415 from deflecting or shaking during movement, thereby ensuring the stability and accuracy of the operation.

[0043] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
