Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a postoperative wound anti-cracking device for pediatric surgical care. Background Art

[0002] Pediatric surgical care refers to comprehensive and meticulous care services for children's surgical diseases and injuries, aiming to promote children's recovery and healthy growth. In the field of pediatric surgical care, the protection of postoperative wounds is crucial, especially for children, who face greater challenges in postoperative wound care due to their lively and active nature. Traditional wound protection methods, such as simple bandaging or using medical tape to fix dressings, often have many shortcomings. For example, too tight a bandage may lead to poor blood circulation and affect wound healing; using medical tape may cause discomfort or even allergies at the adhesive site due to the delicate skin of children, and it is not only difficult to tear off the patch adhered to the skin, but it is also easy to tear the healing wound again in the process, which not only increases the risk of infection, but also may prolong the healing time and bring greater pain to children.

[0003] In order to solve the above problems, some devices for protecting wounds after pediatric surgery have appeared on the market, such as "a patch for easy replacement of dressing core" provided according to Chinese patent authorization announcement No. CN221556310U. When replacing the dressing core, the pressing block on the movable rod can be cancelled by pivoting the pressing cover, so that the elastic support part drives the fixing clip to lift the two ends of the dressing core, making it convenient and quick to replace the dressing core without tearing the patch off the wound, thereby avoiding secondary tearing of the wound.

[0004] However, the patented device has a single function and can only play a simple role in preventing wounds from tearing. It does not take into account that when child patients are active, they may easily pull on the wound due to shaking their arms or legs, causing the wound to crack. In addition, the itching and discomfort that may occur during the wound healing process may also cause child patients to scratch and cause the wound to crack. Summary of the invention

[0031] Embodiment 1, by Figure 1-8 The U-shaped protective cover 4 is connected to the top of the U-shaped protective cover 4, and a limiting groove 41 is provided in the middle of the U-shaped protective cover 4, and an observation flap 5 is connected inside the limiting groove 41. One end of the observation flap 5 is rotatably connected to the limiting groove 41 through a rotating shaft, and the other end is fixedly connected to the limiting spring buckle 51. A through groove 42 is provided in the middle of the inner side of the limiting groove 41, and the through groove 42 is elastically clamped with the limiting spring buckle 51. The limiting spring buckle 51 has anti-cracking relief structures 6 on both sides thereof, and the U-shaped protective cover 4 is connected to auxiliary anti-cracking structures 7 on both sides of the observation flap 5.

[0032] Specifically, the device is used to protect the postoperative wound on the arm or leg of a child patient. First, the adjustable U-shaped plate 1 is placed in the opposite direction of the treatment wound to contact the arm or leg, and the U-shaped connecting pads 2 at both ends are also in contact with it. According to the length of the wound, the adjustable U-shaped plate 1 can be stretched. Next, a plurality of fixing straps 3 are placed around the arm or leg of the child patient, and the Velcro structure is used to bond and fix the U-shaped connecting pad 2 to fix the adjustable U-shaped plate 1 to the arm or leg of the child patient. According to the length of the adjustable U-shaped plate 1, a U-shaped protective cover 4 of the same length is selected to be clamped and fixed to the adjustable U-shaped plate 1. The U-shaped protective cover 4 is provided with a through slot 42 and a hinged transparent observation flap 5, so that the doctor can regularly observe the position of the treatment wound, and the through flap can be opened to change the dressing of the treatment wound. The observation flap 5 is fixed in the limit slot 41 by the limit spring buckle 51 to prevent it from opening automatically when the child shakes his arm or leg. When opening the observation flap 5, the limit spring buckle 51 only needs to be buckled and retracted to be separated from the limit slot 41, and the edge of the observation flap 5 can be opened. Two anti-cracking soothing structures 6 are symmetrically arranged and are located parallel to both sides of the vertical wound. If it is a horizontal wound, the two anti-cracking soothing structures 6 can be horizontally arranged between the horizontal wounds for use. By adjusting, they can be displaced to contact and tilt the skin on both sides of the wound to squeeze it, so that the surrounding skin is close to the wound, which can effectively reduce wound bleeding and promote wound healing. It also prevents children from pulling the wound when shaking their arms or legs, causing the wound to crack, thereby improving safety. Two auxiliary anti-cracking structures 7 are symmetrically arranged on the edge of the U-shaped protective cover 4, which are located parallel to both sides of the vertical wound. If it is a horizontal wound, The two auxiliary anti-cracking structures 7 can be horizontally arranged between the horizontal wounds for use. When the two anti-cracking soothing structures 6 devices squeeze the skin for a long time and cause discomfort, the two auxiliary anti-cracking structures 7 can be replaced with the skin slightly farther away from the wound to be squeezed obliquely. The skin on both sides of the wound can also be squeezed toward the wound, effectively reducing wound bleeding and promoting wound healing. It can prevent child patients from pulling the wound when shaking their arms or legs, causing wound cracking, thereby improving safety. Moreover, by switching between the auxiliary anti-cracking structures 7 and the anti-cracking soothing structures 6 to squeeze the skin, the discomfort can be greatly reduced.

[0033] In this embodiment, the anti-cracking relief structure 6 includes two connecting rods 63 that obliquely penetrate the left and right sides of the observation flap 5. The tops of the two connecting rods 63 are fixedly connected to a connecting plate 61. The middle of the connecting plate 61 is threadedly penetrated with an adjusting bolt 62, and the adjusting bolt 62 is threadedly penetrated and connected to the observation flap 5.

[0034] Specifically, the adjusting bolt 62 is rotated and the observation flap 5 is threadedly rotated downward, driving the two connecting rods 63 connected to the connecting plate 61 downward, and the two buffer springs 66 are compressed and stored to play a buffering role. The pressing base plate 64 at the bottom of the two connecting rods 63 is tilted downward, so that its silicone pad 641 contacts and squeezes the skin of the child patient, driving the skin to be squeezed toward the wound position. The other anti-cracking relief structure 6 device is operated in the same way. By squeezing the skin on both sides of the wound toward the wound, it can effectively reduce wound bleeding and promote wound healing, and prevent the child patient from pulling the wound when shaking his arm or leg, causing the wound to crack, thereby improving safety. Moreover, when the wound is covered with a dressing, the dressing can also be pressed against the limit by the two anti-cracking relief structures 6 devices, without the need to use medical tape to fix it, which is relatively convenient.

[0035] In this embodiment, the adjustable U-shaped plate 1 and the two U-shaped connecting pads 2 can be worn on the arms or legs of the child patient through a plurality of fixing straps 3, so that the device is fixed to facilitate the protection of the treated wound.

[0036] In this embodiment, the component structure of the secondary anti-cracking structure 7 is the same as that of the anti-cracking relief structure 6; two secondary anti-cracking structures 7 are symmetrically arranged on the edge of the U-shaped protective cover 4, and are located parallel to the two sides of the vertical wound. If it is a horizontal wound, the two secondary anti-cracking structures 7 can be horizontally arranged between the horizontal wounds for use. The secondary anti-cracking structure 7 is also composed of a connecting plate 61, an adjusting bolt 62, a connecting rod 63, a pressing base plate 64, a silicone pad 641 and a buffer spring 66. When the two anti-cracking relief structures 6 squeeze the skin for a long time and cause discomfort, the two secondary anti-cracking structures 7 can be replaced with two secondary anti-cracking structures 7 to squeeze the skin slightly farther away from the wound. The skin on both sides of the wound can also be squeezed toward the wound, effectively reducing wound bleeding and promoting wound healing. It prevents children from pulling the wound when shaking their arms or legs, causing wound cracking, thereby improving safety. Moreover, by switching between the secondary anti-cracking structures 7 and the anti-cracking relief structure 6 to squeeze the skin, the discomfort can be greatly reduced.

[0037] The observation flap 5 is a transparent PVC plate or acrylic plate, and has ventilation holes on its surface, so that the doctor can observe the wound regularly. The ventilation holes can facilitate ventilation of the wound and promote healing.

[0039] Specifically, the locking screws 12 are loosened, the U-shaped adjustment plate is grasped to pull the U-shaped extension plate 11 out from the U-shaped telescopic plate, so that the treatment wound is located in the adjustment U-shaped plate 1, and then the locking screws 12 are tightened again.

[0040] In this embodiment, multiple groups of card slots 13 are provided on both sides of the top of the U-shaped telescopic plate and the U-shaped adjustment plate, and multiple groups of V-shaped plug blocks 43 are fixed on both sides of the bottom of the U-shaped protective cover 4. The U-shaped protective cover 4 is inserted into the multiple groups of card slots 13 through the multiple groups of V-shaped plug blocks 43 and is connected with the adjustable U-shaped plate 1 by buckling; according to the length of the adjustable U-shaped plate 1, a U-shaped protective cover 4 of the same length is selected, and the V-shaped plug blocks 43 on both sides are inserted into the card slots 13 on the adjustable U-shaped groove, so that the U-shaped protective cover 4 is fixedly connected with the adjustable U-shaped plate 1 to cover the treated wound for protection.

[0041] Embodiment 2. On the basis of embodiment 1, a soothing slapping mechanism is further provided on the anti-cracking soothing structure 6. The soothing slapping mechanism includes a connecting plate 61 opened on one side of the bottom of the connecting plate 61 and a lower slide groove 642 opened on the top of the pressing bottom plate 64. A displacement rod 67 is connected between the displacement groove 611 and the lower slide groove 642. The displacement rod 67 is fixed with I-shaped sliders 671 on the upper and lower parts. The two I-shaped sliders 671 are respectively slidably connected in the displacement groove 611 and the lower slide groove 642. The left and right interiors of the pressing bottom plate 64 are provided with installation chambers connected to the lower slide groove 642. Two slapping structures 65 are symmetrically installed in the two installation chambers. The displacement rod 67 passes through the observation flip cover 5 to open a movable horizontal groove.

[0042] Specifically, the displacement rod 67 is grasped and moved back and forth between the two beating structures 65, driving the two I-shaped sliders 671 to move in the displacement groove 611 and the lower slide groove 642, driving the two beating structures 65 to beat the skin next to the wound, effectively alleviating the itching discomfort caused by skin healing, preventing child patients from scratching, and improving safety.

[0043] In this embodiment, the beating structure 65 includes a rotating shaft 652 rotatably installed in the installation chamber, a torsion spring 654 is provided on the outside of the rotating shaft 652 and connected to the pressing base plate 64, a shift block 653 is fixed to one side of the outside of the rotating shaft 652, the rotating shaft 652 passes through the pressing base plate 64 to the outside and is fixedly connected to the beating plate 651, the shift block 653 is partially located inside the lower sliding groove 642, and the I-shaped slider 671 is used in conjunction with the shift block 653.

[0044] Specifically, when the I-shaped slider 671 moves to the left, it is squeezed with the shifting block 653 of the left slapping structure 65, driving the shifting material to rotate upward and driving the rotating shaft 652. The rotating shaft 652 rotates clockwise to make the slapping plate 651 tilt up, and at the same time drives the torsion spring 654 to contract and store force. When the I-shaped slider 671 moves to the right and separates from the shifting block 653, the torsion spring 654 rebounds and drives the rotating shaft 652 to make the slapping plate 651 contact and slap the skin near the wound downward, and the I-shaped slider 671 continues to move to the right and contact the right slapping structure 65. The shifting block 653 squeezes and drives the shifting material to rotate upward and drive the rotating shaft 652. The rotating shaft 652 rotates clockwise to make the slapping plate 651 tilt up, and at the same time drives the torsion spring 654 to contract and store force. When the I-shaped slider 671 moves to the left and separates from the shifting block 653, the torsion spring 654 rebounds and drives the rotating shaft 652 to make the slapping plate 651 contact and slap the skin near the wound. The back and forth movement drives the two slapping plates to slap the skin next to the wound, which effectively relieves the itching caused by skin healing, prevents children from scratching, and improves safety.

[0045] Working principle:

[0046] The device is used to protect the postoperative wound on the arm or leg of a child patient. First, the adjustable U-shaped plate 1 is placed in the opposite direction of the wound to be treated so as to contact the arm or leg. The U-shaped connecting pads 2 at both ends are also in contact with the wound. The adjustable U-shaped plate 1 can be lengthened according to the length of the wound.

[0047] Next, a plurality of fixing straps 3 are wrapped around the arms or legs of the child patient, and are bonded and fixed to the U-shaped connection pad 2 through the Velcro structure, and the adjustable U-shaped plate 1 is fixed to the arm or leg of the child patient. According to the length of the adjustable U-shaped plate 1, a U-shaped protective cover 4 of the same length is selected, and the V-shaped plug blocks 43 on both sides are inserted into the card slots 13 on the adjustable U-shaped slot, so that the U-shaped protective cover 4 is clamped and fixed to the adjustable U-shaped plate 1, covering and protecting the wound to be treated, and maintaining a gap to prevent the wound from contacting the outside and causing the wound to rupture, thereby improving safety;

[0048] The U-shaped protective cover 4 is provided with a through slot 42 and is hinged with a transparent observation flap 5, so that the doctor can observe the wound regularly and change the dressing at the wound. The observation flap 5 is fixed in the limit slot 41 by a limit spring buckle 51 to prevent the flap from opening automatically when a child shakes his arms or legs. When opening the observation flap 5, the limit spring buckle 51 can be buckled and retracted to be out of the limit slot 41.

[0049] Two anti-cracking relief structures 6 are symmetrically arranged on the edge of the observation flap 5, and are located parallel to both sides of the vertical wound. If it is a horizontal wound, the two anti-cracking relief structures 6 can be horizontally arranged between the horizontal wounds for use, that is, the adjusting bolt 62 is rotated and the observation flap 5 is threadedly rotated downward to drive the two connecting rods 63 connected to the connecting plate 61 downward, and the two buffer springs 66 are compressed and stored under force, which can play a buffering role. The pressing bottom plates 64 at the bottom of the two connecting rods 63 are tilted downward, so that the silicone pads 641 are in contact and squeezed with the skin of the child patient, driving the skin to be squeezed toward the wound position, and the other anti-cracking relief structure 6 is operated in the same way. By squeezing the skin on both sides of the wound toward the wound, it can effectively reduce wound bleeding and promote wound healing, prevent the child patient from pulling the wound when shaking his arm or leg, causing the wound to crack, and improve safety. Moreover, when the wound is covered with a dressing, the dressing can also be pressed against the limit position by the two anti-cracking relief structures 6, without the need to use medical tape to stick and fix it, which is relatively convenient.

[0050] Two auxiliary anti-cracking structures 7 are symmetrically arranged on the edge of the U-shaped protective cover 4, and are located parallel to both sides of the vertical wound. If it is a horizontal wound, the two auxiliary anti-cracking structures 7 can be horizontally arranged between the horizontal wounds for use. The auxiliary anti-cracking structure 7 is also composed of a connecting plate 61, an adjusting bolt 62, a connecting rod 63, a pressing bottom plate 64, a silicone pad 641 and a buffer spring 66. When the two anti-cracking and soothing structures 6 squeeze the skin for a long time and cause discomfort, the two auxiliary anti-cracking structures 7 can be replaced to squeeze the skin slightly farther away from the wound periphery, which can also squeeze the skin on both sides of the wound toward the wound, effectively reducing wound bleeding and promoting wound healing, preventing children from pulling the wound when shaking their arms or legs, causing the wound to crack, and improving safety. Moreover, the auxiliary anti-cracking structure 7 and the anti-cracking and soothing structure 6 can switch to squeeze the skin, which can greatly reduce discomfort.

[0051] The anti-cracking soothing structure 6 is also provided with a soothing slapping mechanism, which can effectively relieve the itching discomfort caused by skin healing by slapping the skin, that is, grab the displacement rod 67 and move back and forth between the two slapping structures 65, driving the two I-shaped sliders 671 to move in the displacement groove 611 and the sliding groove 642. The two slapping structures 65 are symmetrically arranged, and are composed of a slapping plate 651, a rotating shaft 652, a shifting block 653 and a torsion spring 654, and the shifting block 653 is partially located in the sliding groove 642. When the I-shaped slider 671 moves to the left, it is squeezed with the shifting block 653 of the left slapping structure 65, driving the shifting material to rotate upward and drive the rotating shaft 652. The rotating shaft 652 rotates clockwise to make the slapping plate 651 tilt up, and at the same time drive the torsion spring 654 to contract and store force, while the I-shaped slider 671 When it moves to the right and separates from the shift block 653, the torsion spring 654 rebounds and drives the rotating shaft 652 to make the slapping plate 651 contact and slap the skin near the wound downward, and the I-shaped slider 671 continues to move to the right and squeezes the shift block 653 of the right slapping structure 65, driving the shifting material to rotate upward and drive the rotating shaft 652. The rotating shaft 652 rotates clockwise to make the slapping plate 651 tilt up, and at the same time drives the torsion spring 654 to contract and accumulate force. When the I-shaped slider 671 moves to the left and separates from the shift block 653, the torsion spring 654 rebounds and drives the rotating shaft 652 to make the slapping plate 651 contact and slap the skin near the wound downward. The back and forth movement drives the two slapping plates to slap the skin next to the wound, effectively alleviating the itching discomfort caused by skin healing, preventing children from scratching, and improving safety.
