DETAILED DESCRIPTION

[0017] This part will describe the specific embodiments of the present application in detail, the preferred embodiments of the present application are shown in the drawings, and the drawings are used to supplement the description of the text part of the specification, so that people can intuitively and visually understand each technical feature and the overall technical scheme of the present application, but it cannot be understood as a limitation on the protection scope of the present application.

[0018] REFERENCE Figures 1-7 , the embodiment of the present application is a postoperative rehabilitation nursing device for neural tumors, which comprises: considering the rationality of the overall arrangement, an elastic net cap 2 is designed, the elastic net cap 2 is provided with air holes 1, and a main frame assembly is arranged below the elastic net cap 2. The main frame assembly comprises: a plurality of arc-shaped frame plates 3, a plurality of arc-shaped expansion plates 4, the plurality of arc-shaped frame plates 3 are fixedly connected at equal intervals around the center of the elastic net cap 2 on the lower surface of the elastic net cap 2, the arc-shaped frame plates 3 are all provided with expansion grooves 18, and the two ends of the arc-shaped expansion plates 4 are slidably connected between the adjacent two arc-shaped frame plates 3 through the expansion grooves 18. The elastic net cap 2 realizes air circulation through the air holes 1, the arc-shaped frame plates 3 are fixed around the center of the elastic net cap 2, the arc-shaped expansion plates 4 are connected between the adjacent arc-shaped frame plates 3 through the expansion grooves 18, which not only solves the problem of head moisture, but also fits the head curve through the arc-shaped structure, lays a foundation for subsequent size adjustment, and improves the wearing comfort.

[0019] In order to further realize the precise pressure regulation of the partition, a limiting rod 19 is slidably arranged on the main frame assembly, one end of the limiting rod 19 is fixedly connected with a push plate 20, the front surface of the push plate 20 is fixedly connected with a supporting cushion 21, and the limiting rod 19 is slidably connected in the inside of the arc-shaped frame plate 3. The limiting rod 19 slides in the arc-shaped frame plate 3, the push plate 20 is fixed at one end of the limiting rod 19, the supporting cushion 21 is connected to the front surface of the push plate 20, the push plate 20 and the supporting cushion 21 are moved by the sliding of the limiting rod 19, and the supporting force can be applied or reduced to the specific area of the head, thereby providing structural support for precise pressure regulation.

[0020] Specifically: it can be used to effectively alleviate postoperative edema under the premise of protecting the wound and ensuring safe healing, and create favorable conditions for postoperative recovery of patients, for example, a patient with "right parietal lobe tumor after surgery": the right parietal lobe region after surgery has obvious edema due to surgical trauma, and needs to be pressed to promote lymphatic return to reduce edema, but there is a 3cm surgical wound on the right occiput that needs to be absolutely decompressed to avoid compression healing. At this time, medical staff can move the limiting rod 19 inside the sliding arc-shaped frame plate 3 to drive the push plate 20 and the supporting soft pad 21 on the surface to move - precisely fit the supporting soft pad 21 to the right parietal lobe edema area, and promote the return of edema fluid by slight pressure (the pressure can be finely controlled by the subsequent drive assembly). At the same time, adjust the push plate 20 at the corresponding position of the occiput to make it drive the supporting soft pad 21 away from the wound, keeping the wound area free of pressure contact. The soft material of the supporting soft pad 21 can also avoid the irritation of hard contact to the skin of the edema area, and even when the patient turns over, the soft pad can buffer the pressure change, ensuring stable nursing effect.

[0021] To realize the integration of head circumference adjustment and pressure adjustment and simplify the operation, a plurality of variable direction drive assemblies are arranged on the main frame assembly, and the plurality of variable direction drive assemblies are arranged on the plurality of arc-shaped frame plates 3. The variable direction drive assembly comprises a winding sleeve 15, a drive sleeve 13 and a threaded sleeve 16. The winding sleeve 15 is rotatably connected through the arc-shaped frame plate 3, the drive sleeve 13 is rotatably connected inside the winding sleeve 15, and the threaded sleeve 16 is rotatably connected inside the drive sleeve 13. Two traction lines 17 are fixedly connected to the outer wall of the winding sleeve 15, and the other ends of the two traction lines 17 are fixedly connected to the adjacent arc-shaped expansion plates 4 on one side. The rear surface of the push plate 20 is fixedly connected with a lead screw 22, and the lead screw 22 is screwedly connected in the interior of the threaded sleeve 16. The winding sleeve 15 controls the arc-shaped expansion plate 4 through the traction line 17, the threaded sleeve 16 drives the push plate 20 through the lead screw 22, and the drive sleeve 13 can be matched with the two respectively. Rotating the drive sleeve 13 (with the winding sleeve 15) can adjust the size of the frame and the head circumference, and driving the threaded sleeve 16 can drive the push plate 20 to adjust the pressure, realizing the dual function of a single component and simplifying the operation.

[0022] In order to realize the functions of quick switching head circumference and pressure adjustment, the driving sleeve 13 is provided with a direction changing assembly. The direction changing assembly includes a plurality of sliding grooves 14, a clamping block 9, and a plurality of clamping grooves 8. The plurality of clamping grooves 8 are equidistantly arranged on the inner wall of the winding sleeve 15 and the outer wall of the threaded sleeve 16 around the axis of the driving sleeve 13. The plurality of sliding grooves 14 are equidistantly arranged on the driving sleeve 13 around the axis of the driving sleeve 13, and the clamping block 9 is slidingly connected inside any sliding groove 14. The clamping block 9 is used to change the connection relationship between the driving sleeve 13, the winding sleeve 15, and the threaded sleeve 16. When the clamping block 9 is clamped into the clamping groove 8 on the winding sleeve 15, the driving sleeve 13 rotates coaxially with the winding sleeve 15, and the driving sleeve 13 is rotationally connected with the threaded sleeve 16. When the clamping block 9 is clamped into the clamping groove 8 on the threaded sleeve 16, the driving sleeve 13 rotates coaxially with the threaded sleeve 16, and the driving sleeve 13 is rotationally connected with the winding sleeve 15. The clamping block 9 slides in the sliding groove 14 of the driving sleeve 13, clamps into the clamping groove 8 of the winding sleeve 15 or the threaded sleeve 16, changes the connection object of the driving sleeve 13, and switches the adjustment function by moving the clamping block 9 with the dial plate 11, thereby ensuring that the head circumference and the pressure adjustment do not interfere with each other, and improving the flexibility and accuracy of adjustment.

[0023] Specific scenario 1: It can be used to adapt to the change of head circumference in the edema subsiding period, reduce the stimulation of the wound of the patient, and improve the safety and efficiency of nursing. Postoperative head circumference adjustment in the edema subsiding period: patients after brain tumor surgery usually enter the edema subsiding period in 7-10 days, and the size of the head gradually decreases. If a traditional fixed size device is used, it needs to be frequently replaced to adapt to the head circumference. During the replacement process, it is inevitable to touch the wound or pull the head, which may cause pain or secondary nerve injury. At this time, medical staff only need to clamp the clamping block 9 into the clamping groove 8 of the winding sleeve 15 by the dial plate 11 (described below), so that the driving sleeve 13 rotates coaxially with the winding sleeve 15. Then, rotating the driving sleeve 13 can wind the traction line 17 through the winding sleeve 15, pull the adjacent arc-shaped expansion plate 4 along the expansion groove 18, and gradually reduce the overall size of the main body frame. The whole process does not need to disassemble the device, only needs to rotate the driving sleeve 13 with one hand, and the operation time is not more than 1 minute, which greatly reduces the stimulation to the patient.

[0024] Specific scenario 2: can be used for rapid response to postoperative edema, precise pressure control, and improvement of acute care safety and timeliness. Rapid pressure adjustment in the acute phase: if the patient suddenly has edema in a certain area after surgery (such as edema in the left forehead), the medical staff can immediately dial the dial plate 11 to switch the clamping block 9 to cooperate with the clamping groove 8 of the threaded sleeve 16. At this time, the rotation of the driving sleeve 13 will drive the threaded sleeve 16 to rotate. Because the lead screw 22 is threadedly connected with the threaded sleeve 16, the rotation of the threaded sleeve 16 will push the lead screw 22 to extend forward, thereby driving the push plate 20 and the supporting soft pad 21 to pressurize the edema area, promoting the return of edema fluid. For example, the night nurse finds that the patient's edema has worsened during the ward round. Without the need to find additional tools, pressure adjustment can be completed through only two steps of "dial plate switching + rotating driving sleeve" operation, quickly responding to nursing needs.

[0025] In summary, the improvement of the present embodiment is: The rotating driving sleeve is connected with the winding sleeve, the traction line 17 is wound / unwound to shrink / expand the frame, which is suitable for different head shapes and can also be adjusted to a smaller size as the postoperative edema subsides, without the need to change the device, reducing the touch of the head, avoiding the stimulation of the wound or secondary damage to the nerves. The edema area switching driving sleeve 13 is connected with the threaded sleeve 16, the rotating driving sleeve 13 drives the threaded sleeve 16 to push the push plate 20 to pressurize, the pressure is controllable to promote lymphatic return; the reverse rotating driving sleeve 13 pulls the push plate 20 to reduce pressure in the wound area, while the non-wound area is still pressurized, realizing zoned nursing and solving the problem of avoiding the wound of the traditional device. The reversing assembly makes the switching driving object and the adjustment share the driving sleeve 13. The dialing of the dial plate 11 switches the cooperation of the clamping block 9 and the clamping groove 8, which can switch the head circumference adjustment function and the pressure adjustment function. Finally, both functions are adjusted by the rotating driving sleeve 13, without the need for additional components, simplifying the process, adapting to postoperative patients with weak hands and medical staff who need fast response, and avoiding operation errors.

[0026] On the basis of the above, other structures need to be disclosed in detail, such as: In order to facilitate the user to dial the dial plate, the recess 10 in communication with the sliding groove 14 is arranged on the driving sleeve 13, and the side surface of the clamping block 9 is fixedly connected with the dial plate 11. One side of the dial plate 11 passes through the sliding groove 14 and is located in the recess 10, which is used to facilitate the user to dial the clamping block 9. In order to prevent the clamping block from being loosened at will, the inner surface of the recess 10 is fixedly connected with the rubber rod 12, and the dial plate 11 is slidingly connected through the outer wall of the rubber rod 12, which is used to increase the sliding resistance of the clamping block 9 and prevent it from moving easily. When the driving sleeve 13 is connected with the threaded sleeve 16, the winding sleeve 15 needs to be self-locked to prevent the loosening of the adjusted head circumference, so the driving sleeve 13 is provided with a self-locking assembly, which comprises a ratchet wheel 7 and a pawl 6, the ratchet wheel 7 is fixedly connected to the outer wall of the winding sleeve 15, the pawl 6 is rotatably connected to the front surface of the arc-shaped frame plate 3, the pawl 6 is movably connected with the ratchet wheel 7, the pawl 6 is sleeved with a spring 5 outside the rotating shaft connected with the arc-shaped frame plate 3, one end of the spring 5 is fixedly connected with the arc-shaped frame plate 3, and the other end is fixedly connected with the pawl 6, the ratchet wheel 7 in the self-locking assembly rotates with the winding sleeve 15, the pawl 6 keeps meshing with the ratchet wheel 7 through the spring 5, and the reverse rotation of the winding sleeve 15 is prevented, after the head circumference is adjusted to the position, the pawl 6 automatically locks the ratchet wheel 7, the loosening of the winding sleeve 15 is prevented, the size of the frame is prevented from changing, and the safety and stability of the nursing process are ensured.

[0027] Working principle: when the neuro-oncology postoperative rehabilitation nursing device is used, the elastic net cap 2 is first worn on the head of the patient, the breathable hole 1 realizes the air circulation of the head, and the main frame assembly is attached to the head curve through the arc-shaped frame plate 3 and the arc-shaped telescopic plate 4; When the head circumference is adjusted, the dial plate 11 is actuated to make the clamping block 9 clamped into the clamping groove 8 of the winding sleeve 15, the driving sleeve 13 is rotated to drive the winding sleeve 15 to rotate synchronously, the winding sleeve 15 winds up the traction line 17, the arc-shaped telescopic plate 4 can be pulled into the telescopic groove 18 of the arc-shaped frame plate 3, the frame is reduced to adapt to the small size head type or the head after edema subsides, and the traction line 17 is released, so that the arc-shaped telescopic plate 4 is extended, the frame is expanded to adapt to the large size head type, and meanwhile the pawl 6 of the self-locking assembly is clamped into the ratchet wheel 7 under the action of the spring 5, so that the reverse rotation of the winding sleeve 15 is prevented, and the head circumference size is locked; When the pressure is adjusted, the dial plate 11 is actuated to make the clamping block 9 switched to the clamping groove 8 of the threaded sleeve 16, at this time, the winding sleeve 15 is locked by the self-locking assembly, the driving sleeve 13 is rotated to drive the threaded sleeve 16 to rotate, the threaded sleeve 16 drives the push plate 20 and the supporting soft pad 21 to move towards the head through the lead screw 22, controllable pressure is applied to the edema area to promote lymphatic backflow, the driving sleeve 13 is reversely rotated to drive the push plate 20 and the supporting soft pad 21 to move away from the head, the pressure on the wound area is reduced, the partition nursing is realized, and the rubber rod 12 can increase the sliding resistance of the dial plate 11, avoids the clamping block 9 from being loosened at will, and ensures the adjustment stability.
