Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a nursing device for preventing postoperative infection. Background Technology

[0002] Wound infection refers to inflammation at the site of trauma or a treated wound, characterized by redness, swelling, heat, and pain due to the invasion of bacteria and other microorganisms. Bacterial, fungal, and viral infections are the most common causes of wound infection. Common pathogens include Staphylococcus aureus, Streptococcus, and Candida albicans. Secondly, when the body's immunity is insufficient, the local barrier function weakens, making it unable to effectively resist bacterial and viral invasion, thus increasing the risk of wound infection. Other factors, such as contact with external contaminants (e.g., dust), failure to follow strict sterilization procedures during wound treatment, prolonged surgical time leading to prolonged wound exposure, and certain deep wound types (e.g., animal bites, puncture wounds), can also easily lead to infection.

[0003] Chinese Patent Application Document 1 (Application No.: 2023110505904, Application Date: 2023.08.21) discloses a wound infection prevention and treatment device, including a housing 1' and an adhesive strip 15', with the adhesive strip 15' attached to the rear end of the housing 1'; it also includes: an air pipe 2' connected to the top flange of the housing 1', and an air pump 3' connected to the inner flange of the air pipe 2', the air pipe 2' extending into the interior of the housing 1', and a rotating rod rotating inside the housing 1', with an impeller connected to the top of the rotating rod, and a storage box 6' opened inside the housing 1'. The impeller rotates, driving a reciprocating screw via a pulley assembly. This screw then moves the nozzle, allowing it to spray disinfectant onto the adhesive tape 15'. However, this design is complex and heavy, making it unsuitable for prolonged wear. Even with short-term use, it cannot provide long-lasting sterilization protection, and bacteria can still enter the wound through the adhesive tape 15' (bacteria are smaller than the pores in the tape). Furthermore, this design can easily compress the patient's wound, and not replacing the adhesive tape 15' prevents it from remaining clean in the long term (human skin also secretes dirt, etc.).

[0004] Chinese Patent Application Document 2 (Application No.: 2016207002695, Application Date: 2016.07.04) discloses an infectious disease department wound treatment and disinfection nursing device, including a protective box. Straps 1 and 2 are fixedly connected to the bottom two sides of the protective box, respectively. One side of the protective box has a mounting hole with a mounting shell on it. A rotating shaft is connected to one side of the mounting shell, with a blade fixedly connected to the inner end of the rotating shaft and a hand-drive frame fixedly connected to the outer end. The mounting shell has a vent hole on this side and an air outlet on the other side. The upper end of the protective box has a sliding interface with a pair of sliding blocks slidably connected within it. Each sliding block has a round hole with a post inserted into it. The lower end of the post extends through the lower end of the sliding block and is fixedly connected to a limit block, while the upper end of the post extends through the upper end of the sliding block. A viewing window is hinged to the other side of the protective box. Locking telescopic rods are hinged to one side of each sliding block, and the other end of each locking telescopic rod has a locking hole. The above-mentioned solution also suffers from the problems of being cumbersome, not conducive to long-term use, and having a complex structure that can easily cause inconvenience to daily life. Furthermore, the solution does not include a disinfection facility, making it impossible to disinfect the patient's wound.

[0005] Chinese Patent Application Document 3 (Application No.: 201520808673X, Application Date: October 16, 2015) discloses a novel postoperative care device for infectious diseases, comprising a rectangular base, a vertically mounted linear motor fixed to the base, a bandage changing assembly fixed to the upper end of the motor shaft, the bandage changing assembly including an upper mounting plate and a lower mounting plate, the bottom of the lower mounting plate fixed to the motor shaft, several connecting rods between the upper and lower mounting plates, a circular insertion hole in the middle of the upper mounting plate, and a hand grip mechanism on the lower mounting plate, the hand grip mechanism including a pair of opposing mounting rods, the lower ends of the mounting rods fixed to the lower mounting plate, and a cylindrical grip stick fixed between the upper ends of the mounting rods. The care device also includes a glove device, the glove device including a ring-shaped joint sleeve, the joint sleeve including a pair of rigid blocks hinged to each other, and plastic rings fixed to the sides of the two rigid blocks, the plastic rings having openings. The above-described device is heavy, not portable, and complex to operate, making it unsuitable for quick bandage changing.

[0006] Therefore, providing a nursing device that is not only portable and easy to use, but also provides long-term physical isolation and protection for wounds, has continuous disinfection and sterilization functions, and allows for bandage replacement under disinfection and sterilization conditions, is a technical problem that urgently needs to be solved in this field.

When the inner layer of the rectangular cylindrical shell 211 is fitted with a bandage, the open end of the rectangular cylindrical shell 211 can be closed by a cover 212, which is a rectangular plate. The closing method of the cover 212 and the rectangular cylindrical shell 211 is similar to the buckle of a battery cover. This method is common knowledge in the art, and those skilled in the art can reproduce the technical features through textual description. Therefore, this embodiment will not elaborate further.

[0051] Continue to refer to Figures 2-4 As shown, the cutting component 22 includes a rack 221 and a storage plate 222 that engages in a rectangular groove 1132.

[0052] The rack 221 is a serrated rack 221, with the tips of the rack 221 facing the bottom plate 111 of the groove of the fixed shell 11. The rack 221 is specifically set along the length extension direction of the first through hole 1121 on the edge of the first through hole 1121 away from the bottom plate 111, and the length of the rack 221 is less than the length of the first through hole 1121. Along the thickness direction Z of the bottom plate 111, the top view projection of the end of the rack 221 near the fourth side plate 115 coincides with the top view projection of the end of the first through hole 1121 near the fourth side plate 115.

[0053] The length of the storage plate 222 extends in the thickness direction Z of the bottom plate 111. One end of the storage plate 222 is movably connected within the rectangular groove 1132. The storage plate 222 includes a parallel free end and a fixed end. The storage plate 222 is a rectangular plate with one end movably fixed to the rectangular groove 1132. Along the thickness direction Z of the bottom plate 111, the fixed end of the storage plate 222 is fixed to the side of the rectangular groove 1132 near the bottom plate 111. The free end of the storage plate 222 can be flipped away from the third side plate 113 along the fixed end. The length of the strip 221 is less than the length of the first through hole 1121. The side of the strip 221 near the third side plate 113 of the first through hole 1121 is not aligned with the first through hole 1121. When the bandage is cut by the strip 221 at the first through hole 1121, it is not completely cut by the strip 221. The misalignment between the strip 221 and the first through hole 1121 forms a triangular redundancy. This triangular redundancy of the bandage can be folded towards the third side plate 113 and engaged between the storage plate 222 and the rectangular groove 1132. The storage plate 222 and the rectangular groove 1132 can fix one end of the bandage, preventing it from retracting into the fixing shell 11 after cutting, and allowing the bandage to be pulled out directly for the next use.

[0054] Continue to refer to Figure 2 and Figure 3 As shown, along the thickness direction Z of the bottom plate 111, the top view projections of the first fixing member 13F, the second fixing member 13S, the nozzle 31, the liquid storage box 33, and the storage cylinder 21 do not overlap.

[0055] The liquid storage box 33 is a rectangular bottle. One of its wide sides along its length is fixedly connected to the side of the fourth side plate 115 near the third side plate 113. The liquid storage box 33 is used to hold disinfectant. The disinfectant can be iodine, hydrogen peroxide, or alcohol. The type of disinfectant is not limited in this embodiment and can be selected according to actual needs. On the side of the liquid storage box 33 away from the fourth side plate 115, there is an output port that communicates with the press pump 32 and the nozzle 31. The output port is circular in shape and is fixedly glued to the press pump 32.

[0056] The pump 32 is a cylinder that penetrates the bottom plate 111. The pump 32 passes through a through hole in the bottom plate 111 and is fixedly bonded to the output port of the reservoir 33. The patient can press the pump 32 on the side of the bottom plate 111 away from the infusion port towards the bottom plate 111. The pump 32 can draw out the disinfectant in the reservoir 33 and spray it between the first side plate 112 and the second side plate 114 through the nozzle 31.

[0057] In specific implementation, the nursing device shell for preventing postoperative infection provided in this embodiment can be used for visible external injuries to the patient's upper limbs, such as abrasions and burns. Furthermore, it can also serve as an external isolation protection for the hand after a skin test for convenient daily life. Its specific operation is as follows:

[0058] The first step is to push the first fixing member 13F and the second fixing member 13S inside the fixing shell 11 to the highest point along the thickness direction Z of the bottom plate 111, so that the first fixing member 13F and the second fixing member 13S are close to the bottom plate 111.

[0059] The second step is to press the pump 32 to disinfect the inside of the fixed shell 11. In this embodiment, a bandage roll is loaded into the storage tube 21, so that the starting end of the bandage roll is pulled out from the third through hole 210 of the storage tube 21, and the storage tube 21 is sealed. The storage tube 21 is then inserted into the inside of the fixed shell 11 through the second through hole 1131 of the third side plate 113, with the starting end of the bandage roll facing the first side plate 112 inside the storage tube 21.

[0060] Third, pull the starting end of the bandage roll towards the first side plate 112, so that the starting end of the bandage roll extends from the first through hole 1121 of the first side plate 112 to the outside of the fixing shell 11. The starting end of the bandage roll extending outside the fixing shell 11 is then bent close to the top corner of the third side plate 113 and into the rectangular groove 1132 in a direction away from the rack 221, and fixed in the rectangular groove 1132 by the storage plate 222.

[0061] Fourth, the fixing shell 11 is inverted and placed against the outer wall of the wound, and secured using the fixing strap 12. During this process, the rectangular groove 1132 and the storage plate 222 remain secured. Along the thickness direction Z of the groove bottom plate 111, the first fixing member 13F and the second fixing member 13S are slid away from the groove bottom plate 111, so that the first fixing member 13F and the second fixing member 13S gently press against each other at both ends of the bandage extending along its length.

[0062] When the bandage needs to be changed for the patient, slide the first fixing member 13F and the second fixing member 13S in the fixing shell 11 towards the bottom plate 111 along the thickness direction Z and slide them to the highest point. Then flip the free end of the storage plate 222 away from the third side plate 113 to unlock the rectangular groove 1132 and the storage plate 222; pull the starting end of the bandage roll towards the first side plate 112 and the second side plate 114, and after pulling out an appropriate length, cut it with the rack 221; the excess after the rack 221 is cut is still fixed and engaged in the rectangular groove 1132 and between the storage plate 222. Then repeat the operation in step four, in which the first fixing member 13F and the second fixing member 13S press the bandage together and lock it along the thickness direction Z of the bottom plate 111.

[0063] It should be noted that the press pump 32 can be pressed at any time during the use of this embodiment to disinfect and sterilize the inside of the fixed shell 11.

[0064] Compared with the prior art, the nursing device for preventing postoperative infection provided in this embodiment achieves at least the following beneficial effects:

[0065] First, the nursing device for preventing postoperative infection provided in this embodiment can provide a lightweight and long-lasting physical isolation protection for the wound. First, this embodiment provides a rectangular groove-shaped fixing shell 11 to directly fasten the patient's wound, providing direct physical isolation protection to prevent contamination. Furthermore, the fixing shell 11 provided in this embodiment is made of transparent material, allowing real-time observation of the wound from the outside to check for pus discharge or to detect the real-time recovery of the wound, thereby enabling timely further real-time treatment of the wound, such as sterilization or bandage replacement.

[0066] Secondly, the postoperative infection prevention nursing device provided in this embodiment allows for disinfection and sterilization at any time, maintaining long-term sterilization. Firstly, this embodiment provides a storage box 33 for storing disinfectant, with various disinfectant options available as needed. Furthermore, this embodiment provides a nozzle 31 and a pump 32, which allow the disinfectant to be drawn and sprayed onto the fixing shell 11, directly sterilizing both the fixing shell 11 and the patient's wound. The drawing and spraying of the disinfectant can be used at any time while wearing the postoperative infection prevention nursing device provided in this embodiment, facilitating a long-term sterilization environment for the wound within the fixing shell 11.

[0067] Third, the nursing device for preventing postoperative infection provided in this embodiment allows for rapid bandage replacement under sterilization conditions. The fixing shell 11 of this embodiment first provides a relatively sealed environment, and secondly, the liquid storage box 33 provided in this embodiment disinfects the fixing shell 11 and the patient's wound, enabling isolated, non-contact bandage replacement. Furthermore, this embodiment provides a storage tube 21 to carry the bandage. The first fixing member 13F and the second fixing member 13S can immediately press and fix the bandage onto the patient's skin. Then, a first through hole 1121 and a toothed rack 221 are provided on one side of the first side plate 112, allowing for rapid bandage replacement and cutting.

[0068] In one alternative embodiment, continue to refer to Figures 2-6 As shown, both the first fixing member 13F and the second fixing member 13S include a rectangular fixing block 131, a T-shaped slide bar 132 and a fixing pin 133;

[0069] The fixing block 131 of the first fixing member 13F and the fixing block 131 of the second fixing member 13S are respectively fixedly connected to the side of the fourth side plate 115 near the third side plate 113. Along the direction Y from the third side plate 113 to the fourth side plate 115, the fixing block 131 of the first fixing member 13F and the fixing block 131 of the second fixing member 13S correspond to two fixing through holes 1133 respectively. A strip-shaped sliding groove 1311 is opened in the middle of the side of the fixing block 131 near the third side plate 113. The sliding groove 1311 is recessed towards the side of the fourth side plate 115. The sliding groove 1311 extends along the thickness direction Z of the bottom plate 111. The head end of the slide bar 132 slides into the sliding groove 1311. The tail end of the slide bar 132 is threadedly connected to the fixing pin 133 after corresponding to the fixing through hole 1133. The fixing pin 133 is located on the side of the third side plate 113 away from the fourth side plate 115.

[0070] Specifically, the fixing block 131 is a rectangular body extending along the thickness direction Z of the bottom plate 111. The groove opening of the sliding groove 1311 in the fixing block 131 faces the third side plate 113. The side of the fixing block 131 away from the groove opening of the sliding groove 1311 is fixedly installed on the side of the fourth side plate 115 near the third side plate 113 along the thickness direction Z of the bottom plate 111. One end of the fixing block 131 extending along its length is fixedly connected to the bottom plate 111. Along the thickness direction Z of the bottom plate 111, the periphery of the cross-section of the fixing block 131 is rectangular, and the cross-section of the sliding groove 1311 is convex. The end of the sliding strip 132 away from the third side plate 113 is engaged in the sliding groove 1311.

[0071] The slide bar 132 is a T-shaped strip made of rubber. The T-shaped head of the slide bar 132 is engaged in the convex groove 1311 in the fixing block 131 and can slide up and down along the thickness direction Z of the bottom plate 111. When the slide bar 132 slides along the thickness direction Z of the bottom plate 111 to half the width of the first side plate 112, the slide bar 132 and the fixing block 131 form a T-shaped structure that is perpendicular to each other. The rectangular tail end of the slide bar 132, away from its head end, passes through the third side plate 113 along the direction Y from the third side plate 113 to the fourth side plate 115 and extends out from the fixing through hole 1133 of the third side plate 113.

[0072] The fixing pin 133 can be screwed onto the end of the slide bar 132 away from the fixing block 31. The fixing pin 133 is a screw with its tip facing the slide bar 132. In this embodiment, the fixing pin 133 is cylindrical in shape, but this application does not impose further limitations on this. The fixing pin 133 is used so that the patient can hold it and apply a tightening force to the fixing pin 133. Tightening the fixing pin 133 toward the fixing block 131 can cause the rubber slide bar 132 to expand within the fixing through hole 1133, and allow the slide bar 132 to be relatively and stably fixed at a certain position in the fixing through hole 1133 along the thickness direction Z of the groove bottom plate 111.

[0073] Along the length direction X of the fourth side plate 115, there are two fasteners 13, including a first fastener 13F and a second fastener 13S located at both ends along the length extension direction of the third side plate 113. The first fastener 13F and the second fastener 13S have the same size and structure, and each includes a fixing block 131, a slide bar 132 and a fixing pin 133. The first fastener 13F and the second fastener 13S are respectively located between the third side plate 113 and the fourth side plate 115. The fixing pins 133 of the first fastener 13F and the second fastener 13S extend from the two fixing through holes 1133 of the third side plate 113.

[0074] In actual use, along the thickness direction Z of the bottom plate 111, unlock the fixing pins 133 of the first fixing member 13F and the second fixing member 13S, slide the slide strips 132 of the first fixing member 13F and the second fixing member 13S away from the bottom plate 111, so that the slide strips 132 gently press the bandage at both ends along its length, and then use the fixing pins 133 to lock the slide strips 132 of the first fixing member 13F and the second fixing member 13S again.

[0075] With the above scheme, the first fixing member 13F and the second fixing member 13S can slide up and down along the thickness direction Z of the bottom plate 111, so that the two ends of the bandage can be fixed in motion along the length direction X of the fourth side plate 115, so that the bandage can directly contact the patient's skin.

[0076] In one alternative embodiment, continue to refer to Figure 5 and Figure 6 As shown, the slide bar 132 includes a horizontal block 1321 and a vertical block 1322 integrally connected to the horizontal block 1321. The horizontal block 1321 and the vertical block 1322 form a T-shaped structure. The horizontal block 1321 is inserted into the slide groove 1311, and the vertical block 1322 corresponds to the fixing through hole 1133. It slides up and down along the thickness direction Z of the bottom plate 111 of the groove. The vertical block 1322 is threadedly connected to the fixing nail 133.

[0077] Specifically, both the horizontal block 1321 and the vertical block 1322 are rectangular strips. The length extension direction of the horizontal block 1321 is perpendicular to the length extension direction of the vertical block 1322. One end of the vertical block 1322 is perpendicularly connected to the middle of one side of the horizontal block 1321, and the connection is integrally formed. The entire horizontal block 1321 is set in the groove 1311 of the fixing block 131. The end of the vertical block 1322 away from the horizontal block 1321 passes through the groove 1311 of the fixing block 131 and exits from the fixing through hole 1133 of the third side plate 113 in the direction Y from the third side plate 113 to the fourth side plate 115. The end of the vertical block 1322 away from the horizontal block 1321 is inserted into the side of the third side plate 113 away from the fourth side plate 115.

[0078] With the above scheme, the horizontal block 1321 of the slider 132 can be movably fixed in the groove 1311 of the fixing block 131, so that the horizontal block 1321 can move freely in the thickness direction Z along the bottom plate 111 of the groove, while remaining fixed in the direction Y from the third side plate 113 to the fourth side plate 115. There is no need to fix the horizontal block 1321 separately, and the end of the vertical block 1322 near the horizontal block 1321 is fixed separately.

[0079] In one alternative embodiment, continue to refer to Figure 5 As shown, the fixing nail 133 includes a conical nail post 1331 and a cylindrical nail head 1332, with one end of the nail head 1332 integrally connected to the bottom surface of the nail post 1331 along its length.

[0080] The vertical block 1322 has a conical groove 1320 recessed towards the side of the horizontal block 1321 at the end away from the horizontal block 1321. The conical groove 1320 matches the nail post 1331, and the thread of the nail post 1331 is threadedly connected to the slide bar 132 through the conical groove 1320.

[0081] Specifically, the fixing pin 133 includes a conical pin post 1331 and a cylindrical pin head 1332. The pin post 1331 has a conical groove 1320 with its tip facing the slide bar 132. The outer wall of the pin post 1331 extending along its length is provided with threads that fit into the conical groove 1320 of the slide bar 132. The side of the pin post 1331 away from its tip is fixedly connected to the pin head 1332. The shape of the pin head 1332 can be cylindrical or rectangular. In this embodiment, the shape of the pin head 1332 is cylindrical, but this application does not impose further limitations on this. The pin head 1332 is used so that the patient can hold it and apply tightening force to the pin post 1331.

[0082] The tail end of the slide bar 132 is provided with a conical groove 1320 recessed towards the fixed block 131, and the groove wall of the conical groove 1320 of the slide bar 132 is provided with a thread that matches the nail post 1331.

[0083] With the above method, the nail post 1331 can be tightened in the direction of the fixing block 131, which can cause the rubber slide 132 to expand in the fixing through hole 1133, and make the slide 132 relatively and stably fixed at a certain position of the fixing through hole 1133 along the thickness direction Z of the groove bottom plate 111.

[0084] In an alternative embodiment, reference continues... Figure 2 As shown, the two fixing straps 12 include a left fixing strap 121 and a right fixing strap 122. The left fixing strap 121 is located on the side of the first side plate 112 away from the bottom plate 111, and the right fixing strap 122 is located on the side of the second side plate 114 away from the bottom plate 111.

[0085] The widths of the left fixing strap 121 and the right fixing strap 122 along the third side plate 113 toward the fourth side plate 115 are not greater than the lengths of the first side plate 112 and the second side plate 114 along the first side plate 112 toward the second side plate 114.

[0086] The left fixing strap 121 has a first connector at the end away from the first side plate 112, and the right fixing strap 122 has a second connector at the end away from the second side plate 114 that matches the first connector. The first connector and the second connector are detachably connected.

[0087] Specifically, the fixation strap 12 includes a left fixation strap 121 disposed on the first side plate 112 and a right fixation strap 122 disposed on the second side plate 114. Both the left fixation strap 121 and the right fixation strap 122 are rectangular cloth straps, and the width of both the left fixation strap 121 and the right fixation strap 122 is not greater than the length of the first side plate 112 or the second side plate 114. Through the left fixation strap 121 and the right fixation strap 122, the nursing device for preventing postoperative infection provided in this embodiment can perform closed fixation on the patient's upper limb, specifically through the first connector and the second connector.

[0088] A first connector is provided at the end of the left fixing strap 121 away from the first side plate 112, specifically on the side of the left fixing strap 121 away from the bottom plate 111. A second connector matching the first connector is provided at the end of the right fixing strap 122 away from the second side plate 114, specifically on the side of the right fixing strap 122 close to the bottom plate 111. Both the first and second connectors can be rectangular, and the width of the first and second connectors is not greater than the width of the left fixing strap 121 or the right fixing strap 122. Optionally, the first connector can be a hook and loop fastener, and the second connector can be a hook and loop fastener that matches the first connector.

[0090] In one alternative embodiment, continue to refer to Figure 2 As shown, the first connector is a hook and loop fastener, the length of which extends in the same direction as the length of the left fixing strap 121; the second connector is a hook and loop fastener that matches the hook and loop fastener, the length of which extends in the same direction as the width of the right fixing strap 122, and the hook and loop fastener are bonded together.

[0091] Specifically, the first connector is a hook and loop fastener, the length of which extends in the same direction as the length of the left fixing strap 121. The first connector is sewn onto the left fixing strap 121 at the end away from the first side plate 112 and on the side away from the bottom plate 111. The second connector is a hook and loop fastener that matches the hook and loop fastener, the length of which extends in the same direction as the width of the right fixing strap 122. The hook and loop fastener are bonded together. The second connector is sewn onto the right fixing strap 122 at the end away from the second side plate 114 and on the side away from the bottom plate 111.

[0092] Through the above solution, the nursing device for preventing postoperative infection provided in this embodiment can quickly and repeatedly adhere and fix the patient's upper limb using the first connector and the second connector. This allows the nursing device for preventing postoperative infection provided in this embodiment to adapt to the upper limb thickness of different patients while quickly completing the bonding operation, thus saving manpower.

[0096] The ventilation holes in the above-described design allow for ventilation of the patient's upper limb, enabling effective sweating and heat dissipation at the injured area.

[0097] In one alternative embodiment, continue to refer to Figure 2 and Figure 3 As shown, the liquid storage box 33 has a circular liquid inlet on the side near the bottom plate 111. The bottom plate has two through holes. Along the thickness direction Z of the bottom plate 111, one bottom plate through hole corresponds to the press pump 32, and the other bottom plate through hole corresponds to the liquid inlet. The bottom plate 111 is provided with a plug 331 that matches the liquid inlet. The plug 331 is fastened to the liquid inlet.

[0098] Specifically, the liquid storage box 33 has a liquid inlet on the side near the bottom plate 111, and the liquid inlet is circular in shape. Along the thickness direction Z of the bottom plate 111, the top view projection of the liquid inlet coincides with the top view projection of a bottom plate through hole on the bottom plate 111. There are two bottom plate through holes.

Furthermore, both the filling operation of the disinfectant and the closing operation of the stopper 331 can be performed on the bottom plate 111 away from the liquid storage box 33, which facilitates the replenishment of disinfectant without affecting the patient's use of this embodiment.

[0100] Example 2

[0101] This embodiment is an extension of embodiment 1, and will continue to be referred to... Figure 2 As shown, smooth blocks 1211 are respectively bonded between the side of the first side plate 112 away from the second side plate 114 and the left fixing band 121, and between the side of the second side plate 114 away from the first side plate 112 and the right fixing band 122. The cross-section of the smooth blocks 1211 along their length direction is a right-angled sector.

[0102] Specifically, a smoothing block 1211 is provided on the side of the first side plate 112 away from the second side plate 114, and on the side of the second side plate 114 away from the first side plate 112. The smoothing block 1211 includes a left fan-shaped post provided on the first side plate 112 and the left fixing belt 121, and a right fan-shaped post provided on the second side plate 114 and the right fixing belt 122.

[0103] The left and right sector columns are the same size and made of rubber or silicone. The cross-sections of the left and right sector columns along their length are right-angled sectors. The two rectangular sides of the left sector column are fixedly bonded to the first side plate 112 and the left fixing band 121, respectively. The two rectangular sides of the right sector column are fixedly bonded to the second side plate 114 and the right fixing band 122, respectively.

[0104] The left and right fan-shaped columns of the above scheme can create smooth triangular areas between the first side plate 112 and the left fixing band 121, and between the second side plate 114 and the right fixing band 122, so that the connection between the first side plate 112 and the left fixing band 121, and between the second side plate 114 and the right fixing band 122 is smooth and fluid.
