Description

Technical Field

[0001] The present invention relates to the technical field of postoperative protection, in particular to a breathable postoperative protection device. Background Art

[0002] Postoperative protective devices play an important role in the patient's recovery process. For example, after a patient undergoes thyroid surgery, the thyroid area may be relatively weak and easily damaged. The surgical area usually requires a certain amount of protection and support while maintaining good air permeability to promote wound healing. Therefore, protective devices are needed.

[0003] At present, thyroid patients generally wear a thyroid scarf after surgery. Although this scarf can provide certain protection for the thyroid area, it is relatively soft and cannot effectively limit the patient's head. When the patient's head turns inadvertently, it is easy to cause the wound to tear, which may affect the patient's recovery speed. At the same time, the thyroid scarf fits the patient's neck over a large area and has poor air permeability. When it tightly covers the patient's neck for a long time, it is easy to cause the patient's neck skin to become hot and form acne, affecting the patient's skin health. In view of this, we propose a breathable postoperative protective device. Summary of the invention

[0004] The object of the present invention is to provide a breathable postoperative protective device to solve the problems raised in the above background technology.

[0009] As a further improvement of the present technical solution, the fixing mechanism includes two fixing plates fixedly connected above the protective shell, and limiting holes are provided on the two hollow columns. Bolts are threaded in the limiting holes, and the two bolts pass through the adjacent hollow columns and the through holes on the movable rod in sequence and are threadedly connected to the fixing plates.

[0010] As a further improvement of the technical solution, the ventilation mechanism at least includes a wrapping pad slidably connected in the protective shell cavity, and the side of the wrapping pad close to the neck passes through one side of the protective shell, an annular plate is fixedly connected in the protective shell cavity, and the annular plate is located above the wrapping pad, two extrusion blocks are slidably connected to the annular plate, and the tops of the two extrusion blocks are respectively fixedly connected to the bottoms of adjacent hollow columns, two rectangular grooves are provided on the annular plate, and the rectangular grooves are both slidably connected to limit blocks, the bottom of the limit block is fixedly connected to a fixing rod, and the bottom of the fixing rod passes through the rectangular groove and is fixedly connected to one side of the wrapping pad;

[0011] The extrusion block and the limiting block are both arranged in a triangular shape, and the inclined surfaces of the extrusion block and the limiting block are relatively parallel.

[0012] As a further improvement of the technical solution, a mounting block is fixedly connected to the annular plate, and a No. 1 return spring is fixedly connected to both sides of the mounting block, and the other sides of the two No. 1 return springs are respectively fixedly connected to one side of the adjacent extrusion block.

[0013] As a further improvement of the present technical solution, a plurality of No. 2 return springs are fixedly connected to one side of the wrapping pad located in the protective shell cavity, and the side of the No. 2 return spring away from the wrapping pad is fixedly connected to the inner wall of the protective shell cavity.

[0014] As a further improvement of the technical solution, a plurality of positioning plates are fixedly connected to the inner wall of the protective shell cavity, one side of each positioning plate is rotatably connected to a rotating plate, a plurality of support plates are fixedly connected to one side of the wrapping pad located in the protective shell cavity, a limiting groove is provided on the support plate, and one side of the rotating plate is slidably connected to an adjacent limiting groove;

[0015] The limiting groove is arranged in a wave shape.

[0016] As a further improvement of the technical solution, an inner pad and two protective pads are fixedly connected to the side of the protective shell close to the neck, and the inner pad, protective pad and wrapping pad pass through one side of the protective shell to form a ring.

[0017] As a further improvement of the technical solution, a soft pad is installed on one side of the two L-shaped plates close to the skin.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the breathable postoperative protective device, the bolt installed on the hollow column is manually rotated, and the bolt is passed through the hollow column, the movable rod and the fixed plate in turn, and the bolt is fixed to the fixed plate, so as to fix the hollow column, the movable rod and the L-shaped plate, so as to prevent the rotation of the head from driving the L-shaped plate to rotate, thereby effectively limiting the left and right rotation of the patient's head, thereby avoiding pulling on the wound to the greatest extent.

[0021] 2. In the breathable postoperative protective device, one side of the bolt is removed from the fixing plate by manually turning the bolt installed on the hollow column, and then the bolt is fixed on the hollow column. At this time, when the patient's head turns, the L-shaped plate can be driven to move. The head rotates within a certain range, which can reduce neck stiffness and discomfort caused by keeping the head fixed for a long time. On the other hand, it also helps to promote blood circulation in the neck, which may have a certain positive effect on wound recovery.

[0022] 3. In the breathable postoperative protective device, when the L-shaped plate moves, it cooperates with the movement of the moving rod, hollow column, extrusion block, limit block and fixed rod to drive the wrapping pad to move into the protective shell cavity. At this time, a gap is generated between the wrapping pad and the patient's neck. The gas in the air diffuses from the surrounding environment into the gap with the help of diffusion, further promoting the circulation and exchange of air at the neck, making the device more breathable, improving the comfort of patients when wearing it, and preventing the wrapping pad from long-term contact with the skin, causing heat and acne.

[0038] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-Figure 9 As shown, this embodiment provides a breathable postoperative protective device, including a protective shell 100, on which two face-side limiting mechanisms 200 and a fixing mechanism 300 are provided;

[0040] When the fixing mechanism 300 fixes the face side limiting mechanism 200, the face side limiting mechanism 200 is used to limit the rotation of the patient's head, and limit the patient's head from turning left and right, thereby avoiding to the greatest extent the relatively fragile wound of the patient after thyroid surgery, and the wound is easily pulled by the head turning. When the fixing mechanism 300 is not limited, the face side limiting mechanism 200 is used to control the range of motion of the patient's rotation, and reduce the stiffness and discomfort of the neck caused by keeping the head fixed for a long time;

[0041] A ventilation mechanism 400 is slidingly provided inside the protective shell 100. The ventilation mechanism 400 elastically moves with the face-side limiting mechanism 200 to form a gap with the neck for gas circulation, so that the gas in the air diffuses from the surrounding environment into the gap by diffusion, further promoting the circulation and exchange of air at the neck, making the ventilation effect of the device better.

[0042] The present invention takes into account that thyroid patients generally wear thyroid scarves after surgery. Although this scarf can provide certain protection for the thyroid area, it is relatively soft and cannot effectively limit the patient's head. When the patient's head turns inadvertently, it is easy to cause the wound to tear, which may affect the patient's recovery speed. Therefore, a face-side limiting mechanism 200 and a fixing mechanism 300 are provided. When the patient's wound is at the most vulnerable stage after thyroid surgery, in order to limit the left and right rotation of the head, the face-side limiting mechanism 200 is fixed with the help of the fixing mechanism 300, and the patient's face is fixed between the two face-side limiting mechanisms 200, thereby effectively limiting the left and right rotation of the patient's head, thereby avoiding pulling on the wound to the greatest extent;

[0043] When the patient has passed the early vulnerable stage after surgery and the wound is relatively stable, the fixing mechanism 300 is no longer used to limit the face side limiting mechanism 200. Therefore, when the patient's head turns, the face side limiting mechanism 200 can be driven to move within a certain range. The head turns within a certain range, which can reduce the stiffness and discomfort of the neck caused by keeping the head fixed for a long time. On the other hand, it also helps to promote blood circulation in the neck, which may have a certain positive effect on the recovery of the wound.

[0044] Considering that the thyroid scarf fits closely to the patient's neck over a large area and has poor air permeability, when it tightly covers the patient's neck for a long time, it is easy to cause the skin on the patient's neck to become hot and form acne, affecting the patient's skin health. Therefore, a ventilation mechanism 400 is provided. When the face-side limiting mechanism 200 rotates, it drives the ventilation mechanism 400 to move into the cavity of the protective shell 100. At this time, a gap is generated between the ventilation mechanism 400 and the patient's neck. The gas in the air diffuses from the surrounding environment into the gap with the help of diffusion, further promoting the circulation and exchange of air at the neck, making the ventilation effect of the device better, improving the comfort of the patient when wearing it, and preventing the ventilation mechanism 400 from being in contact with the skin for a long time and causing hotness and acne.

[0045] In order to limit the range of patient head rotation after surgery, Figure 2 and Figure 8As shown, the specific structure of the face side limiting mechanism 200 is further disclosed. The face side limiting mechanism 200 at least includes a hollow column 210 slidably connected to the two slide grooves above the protective shell 100, and the slide groove is provided to provide guidance when the hollow column 210 moves. The hollow column 210 is slidably connected to the inside of each of the moving rods 211, and the two moving rods 211 are slidably connected to the inside of each of the L-shaped plates 212. The moving rod 211 is manually pulled to drive the moving rod 211 to slide inside the hollow column 210, thereby driving the L-shaped plate 212 to move. According to the position of the patient's lower jaw, the height of the moving rod 211 can be appropriately adjusted to adjust the patient's Supporting and fixing the lower jaw can share part of the burden on the neck, reduce the tension of the neck muscles, and improve the patient's comfort. The L-shaped plate 212 is located on one side of the inside of the moving rod 211 and has multiple mounting holes evenly opened. The moving rod 211 also has mounting holes. The position of the L-shaped plate 212 is adjusted according to the size of the patient's face. The L-shaped plate 212 is manually pulled to drive the L-shaped plate 212 to slide inside the moving rod 211. After adjusting to the appropriate position, the mounting bolts are manually rotated to pass the bolts through the mounting holes opened on the moving rod 211 and the L-shaped plate 212 to limit and fix the L-shaped plate 212.

[0046] Considering that the wound is at its most vulnerable stage in the first few days after thyroid surgery, in order to limit the left and right rotation of the head, the face-side limiting mechanism 200 needs to be fixed, such as Figure 2 As shown, the specific structure of the fixing mechanism 300 is further disclosed. The fixing mechanism 300 includes two fixing plates 310 fixedly connected to the top of the protective shell 100. Limiting holes are provided on the two hollow columns 210. Bolts are screwed in the limiting holes, and the two bolts pass through the through holes on the adjacent hollow columns 210 and the moving rod 211 in turn and are threadedly connected to the fixing plates 310. The bolts installed on the hollow columns 210 are manually rotated to pass through the hollow columns 210, the moving rod 211 and the fixing plates 310 in turn, and then the bolts are fixed by nuts to fix the bolts installed on the hollow columns 210 and the fixing plates 310, so as to fix the hollow columns 210 and then the moving rod 211 and the L-shaped plate 212, so as to prevent the L-shaped plate 212 from rotating due to the rotation of the head, thereby effectively limiting the left and right rotation of the patient's head, thereby avoiding pulling on the wound to the greatest extent.

[0047] In order to improve the air permeability of the protective shell 100 and the neck, Figure 3-Figure 4 and Fig. 9As shown, the specific structure of the ventilation mechanism 400 is further disclosed. The ventilation mechanism 400 at least includes a wrapping pad 410 slidably connected in the cavity of the protective shell 100, and the side of the wrapping pad 410 close to the neck passes through one side of the protective shell 100. An annular plate 411 is fixedly connected in the cavity of the protective shell 100, and the annular plate 411 is located above the wrapping pad 410. Two extrusion blocks 412 are slidably connected to the annular plate 411, and the tops of the two extrusion blocks 412 are respectively fixedly connected to the bottoms of adjacent hollow columns 210. Two rectangular grooves are provided on the annular plate 411. The rectangular grooves are provided to provide guidance for the movement of the limit blocks 413, and the limit blocks 413 are slidably connected to the rectangular grooves. The bottom of the limit blocks 413 is fixedly connected to a fixing rod 414, and the bottom of the fixing rod 414 passes through the rectangular groove and is fixedly connected to one side of the wrapping pad 410.

[0048] The extrusion block 412 and the limit block 413 are both arranged in a triangular shape, and the inclined surfaces of the extrusion block 412 and the limit block 413 are relatively parallel, so that when the extrusion block 412 moves, it can squeeze the limit block 413 and drive the limit block 413 to move;

[0049] When the patient's head rotates, since the patient's face side fits against the L-shaped plate 212, the head rotates, driving the L-shaped plate 212 to move, thereby driving the moving rod 211 to move, and then driving the hollow column 210 to move. The movement of the hollow column 210 drives the extrusion block 412 to move, and the extrusion block 412 moves the extrusion limit block 413, driving the limit block 413 to slide in the rectangular groove, thereby driving the fixing rod 414 to move, as shown by arrow a, and then driving the wrapping pad 410 to move into the cavity of the protective shell 100. At this time, a gap is generated between the wrapping pad 410 and the patient's neck. Compared with when the head does not rotate, the wrapping pad 410 fits tightly against the neck. At this time, after a space is generated between the wrapping pad 410 and the patient's neck, the gas in the air diffuses from the surrounding environment into the gap through diffusion, further promoting the circulation and exchange of air, making the device more breathable and improving the comfort of the patient when wearing it.

[0050] Considering that when the head is straightened, the face side limiting mechanism 200 needs to be reset and moved, such as Figure 3 and Figure 4 As shown, a mounting block 420 is fixedly connected to the annular plate 411, and a No. 1 return spring 421 is fixedly connected to both sides of the mounting block 420. The other sides of the two No. 1 return springs 421 are respectively fixedly connected to one side of the adjacent extrusion block 412. When the head rotates, the extrusion block 412 pulls the No. 1 return spring 421 when it moves, causing the No. 1 return spring 421 to deform. When the head is straightened, the No. 1 return spring 421 restores the deformation force, driving the extrusion block 412 to reset and move, preparing for the next head rotation.

[0051] When the head is straightened, the wrapping pad 410 needs to be reset and moved to wrap and fix the patient's neck. Figure 4 and Figure 6 As shown, a plurality of No. 2 return springs 430 are fixedly connected to one side of the wrapping pad 410 located in the cavity of the protective shell 100, and the side of the No. 2 return spring 430 away from the wrapping pad 410 is fixedly connected to the inner wall of the cavity of the protective shell 100. When the limiting block 413 and the fixing rod 414 move, the wrapping pad 410 is driven to move into the cavity of the protective shell 100, and the No. 2 return spring 430 is compressed and deformed. When the head is straightened, the extrusion block 412 does not squeeze the limiting block 413. Under the force of the No. 2 return spring 430 to restore the deformation, the wrapping pad 410 is driven to reset and move, so that the wrapping pad 410 fits tightly against the neck again, providing stable support for the neck.

[0052] In order to improve the air flow effect between the wrapping pad 410 and the gap at the patient's neck, Figure 2 and Figure 7 As shown, a plurality of positioning plates 500 are fixedly connected to the inner wall of the cavity of the protective shell 100, and a rotating plate 510 is rotatably connected to one side of the positioning plates 500. A plurality of support plates 511 are fixedly connected to one side of the wrapping pad 410 located in the cavity of the protective shell 100, and a limiting groove 512 is provided on the support plate 511, and one side of the rotating plate 510 is slidably connected to the adjacent limiting groove 512;

[0053] The limiting groove 512 is arranged in a wave shape. When the wrapping pad 410 moves into the cavity of the protective shell 100, it drives the support plate 511 to move, and drives the rotating plate 510 to slide in the limiting groove 512. Since the limiting groove 512 is wavy, when the support plate 511 moves, it drives the rotating plate 510 to swing, thereby disturbing the gas, promoting the circulation of air, and better penetrating into every part of the neck, further improving the breathability of the device.

[0054] When the ventilation mechanism 400 moves, the protective shell 100 and the neck still need to be fixed to prevent the protective shell 100 from falling off. Figure 1 As shown, an inner pad 110 and two protective pads 120 are fixedly connected to one side of the protective shell 100 close to the neck. The inner pad 110, the protective pad 120 and the wrapping pad 410 pass through one side of the protective shell 100 to form a ring. The medicine bag is pasted on the inner pad 110, and then the protective shell 100 is wrapped around the patient's neck, and the medicine bag is aligned with the postoperative wound so that the medicine bag fits the wound to facilitate the recovery of the wound. The protective pad 120 is arranged so that when the wrapping pad 410 is contracted, the protective pad 120 is still in a fixed state between the neck to prevent the protective shell 100 from loosening and falling off on the neck.

[0055] In order to improve the comfort of the L-shaped plate 212 when it is fixed to the face side, Figure 3As shown, the two L-shaped plates 212 are both installed with cushions 220 on one side close to the skin. When the chin and the side of the face are in contact with the L-shaped plate 212, they are first in contact with the cushions 220, which can disperse the pressure and reduce the sense of oppression on the skin. Especially when the protective shell 100 is worn for a long time, the cushions 220 can greatly improve the patient's comfort.

[0056] The protective shell 100 needs to be fixed to the patient's neck. Figure 1 As shown, a connecting belt 130 is fixedly connected to one side of the protective shell 100, a sub-Velcro is fixedly connected to the connecting belt 130, and a main Velcro is fixedly connected to the outer wall of the protective shell 100. According to the size of the patient's neck, the sub-Velcro on the connecting belt 130 is adhered to the main Velcro on the protective shell 100.

[0057] Working principle: stick the medicine bag to the inner pad 110, then wrap the protective shell 100 around the patient's neck, and align the medicine bag with the postoperative wound. Then, according to the size of the patient's neck, stick the sub-velcro on the connecting belt 130 to the female Velcro on the protective shell 100, and then manually rotate the bolts installed on the two hollow columns 210 to adjust the moving height of the moving rod 211 according to the height of the patient's lower jaw, drive the moving rod 211 to slide inside the hollow column 210, thereby driving the L-shaped plate 212 to move, and manually rotate the two bolts installed on the moving rod 211 to adjust the position of the L-shaped plate 212 according to the size of the patient's face, manually pull the L-shaped plate 212, and drive the L-shaped plate 212 to slide inside the moving rod 211. After adjusting to the appropriate position, manually rotate the bolts installed on the moving rod 211 to limit and fix the L-shaped plate 212, so as to fix the patient's face between the two L-shaped plates 212;

[0058] In the first few days after the patient's thyroid surgery, the wound is at its most vulnerable stage. In order to limit the left and right rotation of the head, at this time, the bolt installed on the hollow column 210 is manually rotated, and the bolt is passed through the hollow column 210, the moving rod 211 and the fixing plate 310 in sequence, and then the bolt is fixed by a nut, thereby fixing the hollow column 210, the moving rod 211 and the L-shaped plate 212 to prevent the L-shaped plate 212 from rotating due to the rotation of the head, thereby effectively limiting the left and right rotation of the patient's head, thereby avoiding pulling on the wound to the greatest extent. At the same time, the L-shaped plate 212 can support and fix the patient's lower jaw, share part of the burden on the neck, reduce the tension of the neck muscles, and improve the patient's comfort;

[0059] When the patient has passed the early vulnerable stage after surgery and the wound is relatively stable, proper head movement can promote blood circulation. At this time, the bolt installed on the hollow column 210 is manually rotated to remove one side of the bolt from the fixing plate 310, and then the bolt is fixed to the hollow column 210 with a nut. When the patient's head turns, the patient's face is in contact with the L-shaped plate 212, and the head turns, driving the L-shaped plate 212 to move. The head turns within a certain range, which can reduce neck stiffness and discomfort caused by keeping the head fixed for a long time, and also helps to promote blood circulation in the neck, which may have a certain positive effect on the recovery of the wound.

[0060] As shown by arrow a, when the L-shaped plate 212 moves, it drives the moving rod 211 to move, thereby driving the hollow column 210 to move. The movement of the hollow column 210 drives the extrusion block 412 to move. The extrusion block 412 moves the extrusion limit block 413, driving the limit block 413 to slide in the rectangular groove, thereby driving the fixing rod 414 to move, and then driving the wrapping pad 410 to move into the cavity of the protective shell 100. At this time, a gap is generated between the wrapping pad 410 and the patient's neck. Compared with when the head does not rotate, the wrapping pad 410 fits tightly against the neck. At this time, after a space is generated between the wrapping pad 410 and the patient's neck, the gas in the air diffuses from the surrounding environment into the gap through diffusion, further promoting the circulation and exchange of air, making the device more breathable and improving the comfort of the patient when wearing it.
