Description

Technical Field

[0001] This application relates to the field of medical rehabilitation equipment technology, specifically a multifunctional walking aid for post-abdominal surgery. Background Technology

[0002] Abdominal surgery can damage the abdominal wall muscles, fascia and other tissues. Postoperatively, the abdominal pressure changes significantly. When getting out of bed and walking, patients not only need to support their body weight, but also need to avoid pulling on the abdominal wound. Therefore, the need for walking support tools is quite special.

[0003] Chinese utility model patent CN223627765U discloses a novel postoperative walking aid for abdominal surgery. Through height adjustment, position adjustment, suspension, and protective mechanisms, as well as components such as a soft pad, a support basket, casters, and counterweights, the device achieves the effects of replacing manual assistance, supporting the patient's upper body, facilitating treatment during activity, preventing chilling, providing stable movement, and ensuring comfortable use. However, this walking aid has limited functionality, providing only support at a fixed height and unable to switch between lumbar support and sitting support modes according to the patient's needs. This makes it difficult for patients to obtain safe and convenient rest support when they are physically exhausted during walking, increasing the risk of falls due to fatigue. In addition, the design of this walking aid focuses on basic support and therapeutic assistance, without fully considering the physical and mental needs of patients during postoperative rehabilitation. It lacks both suitable recreational assistance structures and emergency call design. On the one hand, patients may become irritable and resistant due to boredom when using the walking aid for rehabilitation training for a long time, affecting rehabilitation compliance. On the other hand, when patients suddenly experience severe wound pain, dizziness, nausea, or other discomfort, they cannot promptly send a distress signal to medical staff, which may delay the best treatment opportunity.

[0004] Therefore, this application provides a multifunctional walking aid after abdominal surgery to solve the above-mentioned problems. Summary of the Invention

[0005] This application provides a multifunctional walking aid for post-abdominal surgery, aiming to solve the problem of the limited functionality of existing novel post-abdominal surgery walking aids mentioned in the background art. These aids can only provide basic support and therapeutic assistance at a fixed height, and cannot switch between lumbar support and sitting posture modes to meet the patient's rest needs. Furthermore, they lack entertainment assistance structures and emergency call designs, which not only affect patient rehabilitation compliance but also pose safety hazards such as the inability to seek help in a timely manner when sudden discomfort occurs.

[0006] To achieve the above objectives, this application provides the following technical solution: a multifunctional walking aid after abdominal surgery, comprising symmetrically arranged brackets, a crossbar fixedly connected to one side between the two brackets, brake casters fixedly connected to both ends of the bottom of the brackets, a U-shaped frame fixedly installed on the two brackets for supporting the forearm, a handrail symmetrically fixedly connected to the side of the U-shaped frame away from the bracket for hand support, and a hanging structure set on the crossbar for suspending drainage bags or infusion containers;

[0007] The multi-functional walking aid also includes a dual-purpose support structure for high lumbar support and low sitting posture bearing, which is set on the side of the two brackets away from the U-shaped frame; a placement structure for placing a mobile phone, which is set on the side of the U-shaped frame away from the dual-purpose support structure; and a wireless call device set on the placement structure for triggering medical call signals.

[0008] The dual-purpose support structure includes a support plate disposed between the two supports, a lifting component disposed on the two supports for driving the support plate to a high or low position, a connecting component disposed on the lifting component for connecting with and fine-tuning the support plate, and a support leg disposed on the lifting component for ground support when the support plate descends to a low position. It provides support for patients to walk and stand up through a U-shaped frame and handrails, and allows for convenient hanging of drainage bags or infusion containers via a mounting structure. The lifting component drives the support plate to rise and fall, and the connecting component fine-tunes the support plate's posture. In the high position, it provides lumbar support; in the low position, the support leg touches the ground to assist in forming a stable sitting posture. A placement structure can hold a mobile phone to meet postoperative entertainment needs, and a wireless call device can promptly trigger medical staff calls. It integrates walking support, posture adjustment, medical assistance, and emergency call functions, not only solving the problem of patients having nowhere to rest when physically exhausted while walking, but also providing emergency call safety assurance, thereby improving the convenience and safety of patients during recovery. It is suitable for the multi-scenario use needs of abdominal postoperative patients, reduces the nursing burden, and accelerates the patient's recovery process.

[0009] Preferably, to achieve the hanging and storage of medical supplies, the mounting structure includes a sliding seat slidably fitted onto the horizontal frame and located on the side of the U-shaped frame away from the support plate; a connecting rod fixedly connected to the sliding seat and located between the two handrails; a vertical rod fixedly connected to the end of the connecting rod away from the sliding seat; hooks fixedly connected to the top and bottom of the vertical rod and arranged in a ring for hanging drainage bags or infusion containers; a storage basket fixedly connected to the bottom side of the vertical rod for storing medical accessories; and a locking screw that runs horizontally through one side of the sliding seat and is screwed to the sliding seat to press the sliding seat against the horizontal frame. The sliding seat can slide horizontally along the horizontal frame and be locked in place by the locking screw, thereby adjusting the position of the vertical rod. At the same time, the hooks at the top and bottom of the vertical rod can hang drainage bags or infusion containers respectively, and the storage basket at the bottom can centrally store medical accessories, achieving orderly storage of medical accessories, avoiding the pulling and tangling of tubes, and ensuring medical safety during patient movement.

[0010] Preferably, in order to improve the comfort of patients during use, soft pads are fixedly installed on both the U-shaped frame and the support plate; by adding soft pads to the parts of the U-shaped frame and the support plate that come into contact with the human body, the elastic deformation of the soft pads can increase the contact area, disperse the pressure applied by the human body, thereby relieving the local pressure when the patient's forearm is placed, the waist is supported, or the patient is in a sitting position, avoiding discomfort caused by prolonged contact, and improving the user experience of the walking aid.

[0011] Preferably, to meet the different height requirements for lumbar support and seated posture support, the lifting assembly includes fixed frames respectively fixedly connected to the two brackets and located on both sides of the support plate; sliding grooves respectively opened on the side of the two fixed frames close to each other; lifting frames respectively slidably connected in the two sliding grooves; a lead screw longitudinally passing through one of the fixed frames and the sliding groove and screwed to the corresponding lifting frame; a guide rod fixedly connected in the other sliding groove and passing through the corresponding lifting frame; a protective box fixedly installed on the top of one of the fixed frames and covering the outside of the lead screw; a worm gear fixedly sleeved on the lead screw and located in the protective box; and a rotating... A worm gear is movably connected inside the protective box and meshes with the worm wheel, and a knob is located outside the protective box and fixedly connected to one end of the worm gear. The worm wheel is rotatably connected to one of the fixed frames and the protective box, and the other lifting frame is slidably connected to the guide rod. The support leg is fixedly connected to one side of the bottom of the lifting frame. By rotating the knob, the worm gear is driven to rotate, and then the worm gear meshes with the worm wheel to drive the lead screw to rotate. The lead screw can then drive the lifting frame to rise and fall along the slide groove, realizing the adjustment of the support plate height to meet the different height requirements of the patient's lumbar support and sitting posture. At the same time, the stability of the lifting process can be ensured by the guiding action of the guide rod on the other side.

[0012] Preferably, in order to achieve fine-tuning of the height of the support plate for lumbar support and sitting posture, the connecting assembly includes two lifting slots respectively opened at the ends of the lifting frames away from the corresponding support legs, a sliding frame slidably connected in the two lifting slots and connected to the support plate, and a second locking screw that runs horizontally through one side of the lifting frame and is screwed to the lifting frame to press the sliding frame against the lifting frame; by sliding the sliding frame along the lifting slots and locking it with the second locking screw, the height of the support plate can be finely adjusted to meet the needs of different patients for sitting posture and lumbar support height, improve the flexibility and personalized adaptability of the walker, make the support plate better fit the human physiological curve, and further enhance the comfort of support and load-bearing.

[0013] Preferably, to facilitate the opening and locking of the support plate, the connecting assembly further includes a pivot shaft rotatably connected to one of the sliding frames at the end opposite to the corresponding lifting frame, and a locking screw three extending through one side of the support plate and screwed to the other sliding frame at the end opposite to the corresponding lifting frame and the support plate. The end of the support plate away from the locking screw three is fixedly connected to the pivot shaft. Through the pivot shaft connection, when the patient uses the walker, the support plate can first be rotated to one side to open, and then rotated and locked by the locking screw three for lumbar support or sitting use. This achieves flexible opening and closing and stable locking of the support plate, which not only facilitates the patient's barrier-free access to and from the walker, but also ensures the structural stability under support and load-bearing conditions, improving operational convenience and safety.

[0014] Preferably, in order to improve the stability of the support plate when it is in a low sitting position, the end of the support leg away from the lifting frame is used for a suction cup to adhere to the ground; when the support leg descends with the lifting frame and touches the ground, the suction cup can contact the ground and generate an adsorption force, thereby increasing the connection strength between the support leg and the ground, preventing the walker from sliding or tipping over when the patient is in a sitting position, improving the structural stability in the sitting position, and enhancing the sense of security during use.

[0015] Preferably, to facilitate the placement of the mobile phone, the placement structure includes a connecting plate fixedly connected to the U-shaped frame and located between the U-shaped frame and the vertical rod, a groove formed on the side of the connecting plate away from the handrail for placing the mobile phone, and an inclined plate fixedly connected to the side of the connecting plate near the groove for supporting the mobile phone. The connecting plate is fixed to the U-shaped frame, the groove is used to embed and place the mobile phone, and the inclined plate provides tilt support for the mobile phone, which can ensure the stability of the mobile phone placement, thereby facilitating patients to watch videos and listen to music after surgery, relieving anxiety during the rehabilitation process, and improving the patient's rehabilitation experience.

[0016] Preferably, in order to store and place the wireless pager, the connecting plate is provided with a placement slot for placing the wireless pager; by providing a placement slot on the connecting plate, the wireless pager can be placed in the placement slot for storage, thereby achieving fixed storage and convenient access to the wireless pager.

[0017] This multifunctional walking aid for post-abdominal surgery provides support for patients to walk and stand up through a U-shaped frame and handrails. The mounting structure allows for convenient suspension of drainage bags or infusion containers. A lifting component drives the support plate to rise and fall, and the connecting components fine-tune the plate's posture. In a high position, it provides lumbar support; in a low position, the supporting legs touch the ground to assist in a stable sitting posture. A storage structure can hold a mobile phone to meet post-operative entertainment needs, and a wireless call device can promptly trigger medical staff calls. Integrating walking support, posture adjustment, medical assistance, and emergency call functions, it not only solves the problem of patients having nowhere to rest when physically exhausted while walking but also provides emergency call safety assurance, thereby improving the convenience and safety of patients during recovery. It is suitable for the multi-scenario use needs of post-abdominal surgery patients, reduces the burden of nursing care, and accelerates the patient's recovery process. Attached Figure Description

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] This embodiment provides a multifunctional walking aid for post-abdominal surgery, such as... Figures 1-8As shown, the multi-functional walking aid includes symmetrically arranged brackets 1, a crossbar 11 fixedly connected to one side between the two brackets 1, brake casters 12 fixedly connected to both ends of the bottom of the brackets 1, a U-shaped frame 2 fixedly installed on the two brackets 1 for supporting the forearms, handrails 3 symmetrically fixedly connected to the side of the U-shaped frame 2 away from the brackets 1 for hand support, and a hanging structure 4 set on the crossbar 11 for suspending drainage bags or infusion containers; the multi-functional walking aid also includes a dual-purpose support seat set on the side of the two brackets 1 away from the U-shaped frame 2 for high-level lumbar support and low-level sitting support. Structure 5, a placement structure 6 for placing a mobile phone on the side of the U-shaped frame 2 away from the dual-purpose support structure 5, and a wireless call device 7 for triggering medical call signals on the placement structure 6; the dual-purpose support structure 5 includes a support plate 51 disposed between two brackets 1, a lifting assembly 52 disposed on the two brackets 1 for driving the support plate 51 to a high or low position, a connecting assembly 53 disposed on the lifting assembly 52 for connecting and fine-tuning with the support plate 51, and a support leg 54 disposed on the lifting assembly 52 for touching the ground and supporting the support when the support plate 51 descends to a low position.

[0037] When in use, medical staff or caregivers can first lock or release the brake casters 12 as needed to ensure the walker can stop stably or move smoothly during use. When the patient gets out of bed, they can place their forearms on the U-shaped frame 2 and hold the handrails 3 on the side of the U-shaped frame 2 away from the support 1. The load-bearing effect of the U-shaped frame 2 on the forearms and the gripping support of the handrails 3 distribute the body load and reduce the stress on the abdominal wound. At the same time, medical staff or caregivers can hang drainage bags or infusion containers through the hanging structure 4 to meet the medical needs of the patient when getting out of bed. However, when the patient walks, the dual-purpose support structure 5 can be operated to drive the support plate 51 to rise and fall through the lifting component 52, adjusting the support plate 51 to a high position so that it fits the patient's waist position, providing lumbar assistance when the patient walks and reducing compensatory pressure on the waist. When the patient needs to sit down to rest, the support plate 51 can be lowered to a low position through the lifting component 52. The support leg 54 connected to component 52 descends synchronously with the support plate 51 and touches the ground, providing additional support to the support plate 51 and preventing it from swaying due to the load. At the same time, when supporting the waist or sitting, the position and angle of the support plate 51 can be finely adjusted through the connecting component 53 to meet the different needs of patients, improving lumbar support and sitting comfort. In addition, patients can place their mobile phones in the placement structure 6 while using the walker, making it convenient for them to watch videos and listen to music after surgery, relieving anxiety during the rehabilitation process and improving the patient's rehabilitation experience. In case of sudden discomfort, the wireless caller 7 placed on the placement structure 6 can be used directly to trigger a medical call signal to obtain timely assistance from medical personnel. The entire device, through the coordinated cooperation of its various components, realizes multiple functions such as walking support, lumbar support, sitting support, medical assistance, and emergency call, comprehensively meeting the rehabilitation needs of patients after abdominal surgery.

[0038] It should be added that the wireless pager 7 has a built-in wireless radio frequency module, which can establish a signal connection with the call receiving terminal in the hospital ward. After the patient presses the pager button, the signal will be transmitted to the host system at the nurse station in real time. The host system can display the caller's ward number and bed information, which makes it easy for medical staff to quickly locate and provide timely assistance.

[0039] Specifically, the mounting structure 4 includes a sliding seat 41 that is slidably sleeved on the cross frame 11 and located on the side of the U-shaped frame 2 away from the support plate 51; a connecting rod 42 that is fixedly connected to the sliding seat 41 and located between the two handrails 3; a vertical rod 43 that is fixedly connected to the end of the connecting rod 42 away from the sliding seat 41; hooks 44 that are fixedly connected to the top and bottom ends of the vertical rod 43 and are arranged in a ring for hanging drainage bags or infusion containers; a storage basket 45 that is fixedly connected to the bottom side of the vertical rod 43 for storing medical accessories; and a locking screw 46 that runs horizontally through one side of the sliding seat 41 and is screwed to the sliding seat 41 to press the sliding seat 41 against the cross frame 11.

[0040] Medical staff, caregivers, or patients can, according to actual needs, first loosen the locking screw 46 that runs through and is screwed to one side of the sliding seat 41, releasing the locking screw 46 from its restraining limit on the sliding seat 41. Then, push the connecting rod 42, which is fixedly connected to the sliding seat 41, causing the sliding seat 41 to slide horizontally along the length of the crossbeam 11. This adjusts the position of the vertical rod 43, which is fixedly connected to the end of the connecting rod 42 away from the sliding seat 41, so that the vertical rod 43 can match the patient's position and prevent suspended medical supplies from pulling on the tubing. After adjusting to the appropriate position, tighten the locking screw 46, using the end of the locking screw 46 to press against the crossbeam 11. The outer wall of the vertical rod 43 is used to fix the sliding seat 41 on the horizontal frame 11. Then, the drainage bag or infusion container can be suspended on the hooks 44 that are distributed in a ring at the top and bottom of the vertical rod 43 to meet the infusion or drainage needs of patients when they get out of bed. At the same time, smaller medical accessories such as gastric tube negative pressure suction trays can be placed in the storage basket 45 that is fixedly connected to the bottom side of the vertical rod 43 to achieve centralized storage and orderly management of medical supplies. The entire mounting structure 4 achieves flexible adaptation of the mounting position of medical supplies through the cooperation of sliding adjustment and locking fixation, ensuring the safety of the tubing during patient activities and improving the practicality and convenience of medical auxiliary functions.

[0041] In order to improve the comfort of patients during use, soft pads 8 are fixedly installed on both the U-shaped frame 2 and the support plate 51. By adding soft pads 8 to the parts of the U-shaped frame 2 and the support plate 51 that come into contact with the human body, the elastic deformation of the soft pads 8 can increase the contact area and disperse the pressure applied by the human body, thereby relieving the local pressure when the patient's forearm is placed, the waist is supported, or the patient is in a sitting position, avoiding discomfort caused by prolonged contact, and improving the user experience of the walking aid.

[0042] Furthermore, the lifting assembly 52 includes fixed frames 521 respectively fixedly connected to two brackets 1 and located on both sides of the support plate 51; slide grooves 522 respectively opened on the side of the two fixed frames 521 close to each other; lifting frames 523 respectively slidably connected in the two slide grooves 522; a screw rod 524 longitudinally passing through one of the fixed frames 521 and the slide groove 522 and screwed to the corresponding lifting frame 523; a guide rod 525 fixedly connected in the other slide groove 522 and passing through the corresponding lifting frame 523; and a guide rod 525 fixedly installed in one of the fixed frames 521. 21. A protective box 529 is placed on top and covers the outside of the lead screw 524. A worm gear 526 is fixedly sleeved on the lead screw 524 and located inside the protective box 529. A worm 527 is rotatably connected inside the protective box 529 and meshes with the worm gear 526. A knob 528 is set outside the protective box 529 and fixedly connected to one end of the worm 527. The worm gear 526 is rotatably connected to one of the fixed brackets 521 and the protective box 529. Another lifting frame 523 is slidably connected to the guide rod 525. The support leg 54 is fixedly connected to one side of the bottom of the lifting frame 523.

[0043] When the height of the support plate 51 needs to be adjusted for lumbar support or sitting posture, the user turns the knob 528. The knob 528 drives the worm gear 527 to rotate synchronously. Utilizing the meshing transmission characteristics of the worm gear 527 and the worm wheel 526, the rotational motion of the worm gear 527 is converted into the rotational motion of the worm wheel 526, which in turn drives the lead screw 524 to rotate. When the lead screw 524 rotates, the lifting frame 523 screwed to it will move up and down along the slide groove 522. The lifting frame 523 on the other side slides synchronously along the guide rod 525, ensuring the synchronicity and stability of the movement of the two lifting frames 523. The support leg 54, which is fixedly connected to one side of the bottom of the lifting frame 523, will move up and down with the lifting frame 523. The lifting mechanism allows for step-by-step adjustment. When the support plate 51 is lowered to a low position and can be used as a seat cushion, the support legs 54 can touch the ground to provide additional support and enhance structural stability. When the support plate 51 is raised to a high position to support the patient's lower back while walking, the support legs 54 will rise synchronously with the lifting frame 523 to lift off the ground without hindering the patient's walking movements. After adjustment, the self-locking characteristics of the worm gear 527 and worm wheel 526 meshing transmission can firmly lock the positions of the lifting frame 523 and the support plate 51, preventing them from sliding down on their own during use and ensuring the stability of the lumbar support or sitting posture, thereby meeting the patient's usage needs in different scenarios.

[0044] Furthermore, the connecting component 53 includes lifting slots 531 with two lifting frames 523 respectively located away from the end of the corresponding support leg 54, sliding frames 532 respectively slidably connected in the two lifting slots 531 and connected to the support plate 51, and locking screw 533 that extends laterally through one side of the lifting frame 523 and is screwed to the lifting frame 523 to press the sliding frame 532 against the lifting frame 523; the connecting component 53 also includes a rotating shaft 534 rotatably connected to one of the sliding frames 532 away from the end of the corresponding lifting frame 523, and a locking screw 535 that extends through one side of the support plate 51 and is screwed to the support plate 51 at the end of the other sliding frame 532 away from the corresponding lifting frame 523. The end of the support plate 51 away from the locking screw 535 is fixedly connected to the rotating shaft 534.

[0045] Before the patient uses the walker, medical staff, caregivers, or the patient can first loosen the locking screw 535 to release its fixing limit on the support plate 51 and the corresponding sliding frame 532. Since the support plate 51 is rotatably connected to the sliding frame 532 on the other side via the pivot 534, after unlocking, the support plate 51 can be rotated to one side around the pivot 534, leaving enough space for the patient to support their forearm on the U-shaped frame 2 and hold the handrail 3. After the patient adjusts their position, rotate the support plate 51 in the opposite direction to return it to a position suitable for lumbar support or sitting posture. Then tighten the locking screw 535 to firmly lock the end of the support plate 51 away from the pivot 534 onto the corresponding sliding frame 532, completing the process. The support plate 51 is installed and fixed. When the height of the support plate 51 needs to be finely adjusted according to the patient's usage needs, the locking screw 2 533 can be loosened to release its clamping effect on the sliding frame 532. The sliding frame 532 is pushed to slide up and down along the length of the lifting groove 531, thereby driving the support plate 51 to make a small range of height adjustment. After adjusting to a comfortable position that fits the patient's waist curve or hip contour, the locking screw 2 533 is tightened again. The clamping force at the end of the locking screw 2 533 is used to fix the sliding frame 532 in the lifting groove 531, ensuring the height of the support plate 51 is stable. This adapts to the different needs of the patient's waist support and sitting posture, ensuring comfort and stability during use.

[0046] It is worth noting that the end of the support leg 54 away from the lifting frame 523 is used for the suction cup 55 that adheres to the ground;

[0047] When the support plate 51 is lowered to a low position via the lifting assembly 52 to serve as a cushion for the patient to rest, the support leg 54 moves downward synchronously with the lifting frame 523 until the suction cup 55 at its bottom is in full contact with the ground. At this time, the patient sits on the support plate 51, and the body weight is transferred through the support plate 51 to the lifting frame 523, and then from the lifting frame 523 to the support leg 54, causing the suction cup 55 to be subjected to downward pressure. This expels the air between the suction cup 55 and the ground, creating a negative pressure adsorption state. Atmospheric pressure is used to firmly adhere the suction cup 55 to the ground, effectively increasing the friction between the support leg 54 and the ground. The structure features a friction and connection stability mechanism to prevent the walker from sliding or tipping over while the patient is seated. When the support plate 51 needs to be raised to a higher position for lumbar support or when the patient gets up to walk, the lifting assembly 52 drives the lifting frame 523 to rise. The support leg 54 moves upward synchronously with the lifting frame 523, the suction cup 55 disengages from the ground, and the negative pressure adsorption is released, thus not hindering the movement of the walker or the patient's walking. The entire structure significantly improves the stability of the support plate 51 when it is in a low position through the adsorption effect of the suction cup 55, ensuring the safety of the patient when using it in a seated position.

[0048] Furthermore, the placement structure 6 includes a connecting plate 61 fixedly connected to the U-shaped frame 2 and located between the U-shaped frame 2 and the vertical rod 43, a groove 62 formed on the side of the connecting plate 61 away from the handrail 3 for placing a mobile phone, and an inclined plate 63 fixedly connected to the side of the connecting plate 61 near the groove 62 for supporting the mobile phone.

[0049] When using the walker, if a patient needs to place their mobile phone for entertainment purposes such as watching videos or listening to music after surgery, or for temporary placement, they can directly place the phone into the groove 62 on the connecting plate 61. At this time, the bottom of the phone will contact the inclined plate 63, which provides tilt support for the phone, keeping it at a suitable tilt angle. This allows the patient to clearly view the phone screen while standing or sitting, without needing to hold the phone, effectively freeing the patient's hands and preventing the patient from affecting their grip on the handrail 3, thus ensuring safety during walking. Because the groove 62 provides lateral and longitudinal restraint for the phone, and the inclined plate 63 provides support, even if the walker shakes slightly during movement, the phone will remain stably placed in the groove 62 without slipping. This meets the patient's entertainment and communication needs during postoperative rehabilitation, improving the patient's comfort and rehabilitation experience.

[0050] In addition, in order to store the wireless pager 7, a placement slot 64 for placing the wireless pager 7 is provided on the connecting plate; by opening the placement slot 64 on the connecting plate 61, the wireless pager 7 can be placed in the placement slot 64 for storage, so as to realize the fixed storage and convenient access of the wireless pager 7.

[0051] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
