Description

Technical Field

[0001] The present invention relates to the field of orthopedic nursing, and particularly to a clamping device for orthopedic nursing. Background Art

[0002] Orthopedic nursing refers to the professional nursing services provided to patients suffering from diseases or injuries of bones, joints, muscles and surrounding soft tissues. This includes nursing throughout the process from prevention, treatment to rehabilitation, aiming to help patients relieve pain, promote functional recovery, improve quality of life, prevent complications, and guide patients to perform appropriate rehabilitation training.

[0003] During the orthopedic nursing process, fixing the injured leg of the patient is a crucial step in the rehabilitation process. However, simply relying on traditional fixing methods such as plaster, bandage or simple brackets often neglects to provide sufficient and uniform support for the injured leg of the patient. During the fixation of the injured leg of the patient, if the injured leg of the patient is in a straight state for a long time, coupled with the local compression of the fixing device, it is easy to cause poor blood circulation, increasing the risk of deep vein thrombosis. And when the patient needs to stay in bed for a long time, if the fixing device cannot evenly disperse the pressure, the local high-pressure area may cause skin damage and even pressure sores, increasing the risk of complications and reducing the efficiency and comfort of the rehabilitation process of the injured leg of the patient.

[0004] In view of the above problems, it is necessary to design an orthopedic nursing clamping device for lifting and flexing the injured leg of the patient. Summary of the Invention

[0005] In order to overcome the drawback that if the injured leg of the patient is in a straight state for a long time, coupled with the local compression of the fixing device, it is easy to cause poor blood circulation and increase the risk of deep vein thrombosis, the present invention provides an orthopedic nursing clamping device.

[0006] The technical solution of the present invention is: an orthopedic nursing clamping device, including a first support plate, an L-shaped plate, a fixing plate, a first screw rod, a support mechanism, an arc-shaped ring plate, a female buckle, a male buckle and a pushing mechanism. The front parts of both left and right sides of the first support plate are connected with L-shaped plates. The horizontal part of the L-shaped plate is in screw-threaded connection with the first screw rod. The inner side of the vertical part of the L-shaped plate is slidably connected with a fixing plate. The bottom end of the first screw rod is rotatably connected with the top of the fixing plate. The first support plate is provided with a support mechanism for fixing the arc-shaped ring plate. The arc-shaped ring plate is used for limiting the patient's leg. There are two arc-shaped ring plates. The front sides of the two arc-shaped ring plates are both connected with female buckles at intervals through elastic bandages. The rear sides of the two arc-shaped ring plates are both connected with male buckles at intervals through elastic bandages. The male buckle is in clamping fit with the female buckle. The upper part of the first support plate is provided with a pushing mechanism for slightly flexing the patient's knee.

[0007] Further, the supporting mechanism includes an L-shaped threaded sleeve, a cylindrical sleeve, a second support plate, a torsion spring, and a fixed threaded sleeve. Two fixed threaded sleeves are symmetrically arranged on the left and right of the top of the first support plate. The cylindrical sleeve is sleeved on the fixed threaded sleeve. The top of the fixed threaded sleeve is sleeved with an L-shaped threaded sleeve. The internal thread of the cylindrical sleeve is screwed with the external threads of the fixed threaded sleeve and the L-shaped threaded sleeve. The horizontal ends of the L-shaped threaded sleeve are rotatably connected to a second support plate. A torsion spring is connected between the second support plate and the L-shaped threaded sleeve. An arc-shaped ring plate is arranged between the two second support plates on the same side.

[0008] Further, the pushing mechanism includes a double-shaft motor, a second screw rod, a guide frame, a sliding shaft, a connecting rod, a guide rod, a cushion holder, and a sliding rod. A double-shaft motor is installed in the middle of the upper part of the first support plate. The left and right of the middle part of the first support plate are symmetrically connected with rotating shafts, and the rotating shafts are connected to the output shafts of the double-shaft motor. Second screw rods are connected to the mutually remote ends of the two rotating shafts. Guide frames are symmetrically connected to the front and back of the first support plate with respect to the second screw rods. A sliding shaft is slidably connected between the two guide frames on the same side. A nut is embedded in the middle of the sliding shaft. The sliding shaft is screwed with the second screw rod through the nut. Connecting rods are rotatably connected to both ends of the sliding shaft. Guide rods are symmetrically and vertically connected to the front and back of the middle part of the first support plate. A sliding rod is slidably connected to the guide rod. A cushion holder is connected between the two sliding rods. The other side of the connecting rod is rotatably connected to the adjacent sliding rod.

[0009] Further, a reinforcement mechanism is further included. The reinforcement mechanism is arranged inside both arc-shaped ring plates. The reinforcement mechanism includes an arc-shaped air cushion, an air inlet pipe, a sealing cover, and an air outlet valve. Arc-shaped air cushions are arranged inside both arc-shaped ring plates. Air inlet pipes are connected to the front sides of the two arc-shaped air cushions. A sealing cover is rotatably connected to the air inlet pipe. Air outlet valves are installed on the front sides of the two arc-shaped air cushions. The air outlet valves are located on the right side of the air inlet pipe.

[0010] Further, a storage mechanism is further included. The storage mechanism is arranged below the first support plate. The storage mechanism includes a storage box, a rotating frame, a magnetic suction door, a magnetic strip, a wedge-shaped block, and an elastic member I. A rotating frame is rotatably connected to the front side of the storage box. The rotating frame is connected to the first support plate by bolts. A magnetic strip is connected to the front side of the storage box. A magnetic suction door is connected to the front side of the magnetic strip. The magnetic suction door is magnetically connected to the magnetic strip. A wedge-shaped block is slidably connected to the left side of the storage box. An elastic member I is connected between the wedge-shaped block and the storage box.

[0011] Further, it further includes a disinfection mechanism. A disinfection mechanism is provided inside the storage box. The disinfection mechanism includes a liquid storage tank, a one-way flow pipe, a liquid extraction cylinder, an elastic member II, a piston plate, a spray head, a pull rope, a guide rod, a sliding frame, an elastic member III, and a rotating plate. The liquid storage tank is provided at the rear side inside the storage box. The left and right sides of the rear side inside the storage box are symmetrically connected with liquid extraction cylinders. One-way flow pipes are connected between the two liquid extraction cylinders and the liquid storage tank. A piston plate is slidably connected inside the liquid extraction cylinder. An elastic member II is connected between the piston plate and the liquid extraction cylinder. A spray head is provided between the two liquid extraction cylinders. Two groups of guide rods are symmetrically connected to the left and right sides of the rear side inside the storage box. A sliding frame is slidably connected between the two guide rods in the same group. A pull rope is connected to the front side of the piston plate. The pull rope slidably penetrates through the liquid extraction cylinder and is fixedly connected to the sliding frame. A rotating plate is rotatably connected to the sliding frame. An elastic member III is connected between the rotating plate and the sliding frame.

[0012] Further, a plurality of symmetrically distributed air holes are formed in the two arc-shaped ring plates, and a plurality of symmetrically distributed air holes are also formed in the two arc-shaped air cushions.

[0013] Further, the pad holder is designed to be semi-circular.

[0014] The beneficial effects of the present invention are as follows: 1. Through the cooperation of the pushing mechanism, the L-shaped threaded sleeve, and the second support plate, when the double-shaft motor operates, the driving shaft rotates, the driving shaft drives the second screw rod to rotate, the second screw rod drives the sliding shaft to move along the guide frame. During the movement of the sliding shaft, the connecting rod rotates along the sliding shaft. At the same time, the other side of the connecting rod drives the sliding rod and the pad holder to move along the guide rod. The pad holder fits against the back side of the patient's knee and drives it to move. When the patient's knee is slightly bent, the injured thigh and calf of the patient respectively drive the corresponding arc-shaped ring plate and the second support plate to rotate along the L-shaped threaded sleeve, which is convenient for helping the injured leg of the patient prevent the formation of deep vein thrombosis.

[0015] 2. Through the cooperation of the arc-shaped air cushion, the air inlet pipe, and the sealing cover, the medical staff pulls the sealing cover to rotate and open it, then connects the air charging pipe of the air inflator to the air inlet pipe. After ensuring its stable connection, the air inflator is turned on, so that the gas enters the air inlet pipe through the air charging pipe, and then is transported from the air inlet pipe to the arc-shaped air cushion, prompting the arc-shaped air cushion to gradually expand until the arc-shaped air cushion reaches an appropriate size. After the inflation is completed, the air inflator is turned off, and the air charging pipe is disconnected to prevent excessive gas filling. Then, the sealing cover is pulled to rotate in the reverse direction and covered back on the air inlet pipe to ensure the airtightness of the arc-shaped air cushion and avoid accidental loss of gas during the use of the arc-shaped air cushion, which helps to evenly apply a supporting force to the injured leg of the patient, reduce local pressure, and also helps to prevent poor blood circulation that may be caused by long-term bed rest.

[0016] 3. Through the cooperation of the rotating frame, storage box, magnetic door, magnetic strip, wedge block and elastic member I, the medical staff pull the magnetic door open again, causing the magnetic door to be separated from the magnetic strip. Subsequently, after the medical staff lift the injured leg of the patient to an appropriate height, they pull the first support plate to drive the rotating frame to rotate in the reverse direction along the storage box. The first support plate drives all the components on it to rotate in the reverse direction. At the same time, the first support plate rotates in the reverse direction and contacts the wedge block, and squeezes the wedge block again, causing the wedge block to move along the storage box. When the first support plate drives all the components on it to rotate in the reverse direction to the initial position, the first support plate is released. Subsequently, the first support plate no longer contacts the wedge block. Under the reset action of the elastic member I, the wedge block moves along the storage box to the initial position, facilitating the fixation of the first support plate. The magnetic door is placed on the magnetic strip again. Due to the magnetic force, an attractive force is generated between the magnetic door and the magnetic strip, ensuring that the magnetic door closes tightly again. Finally, the injured leg of the patient is slowly placed on the hospital bed to ensure the safety and comfort of the patient.

[0017] 4. Through the cooperation of the liquid storage tank, one-way flow pipe, liquid pumping cylinder, elastic member II, piston plate, nozzle, pull rope, guide rod, sliding frame and rotating plate, when the first support plate rotates in the reverse direction and contacts the rotating plate, it pushes the rotating plate to drive the sliding frame to move along the guide rod. The movement of the sliding frame drives the pull rope to move along the liquid pumping cylinder. The movement of the pull rope drives the piston plate to move along the liquid pumping cylinder, and the elastic member II is compressed. Since the movement of the piston plate causes the internal volume of the liquid pumping cylinder to increase and the air pressure to decrease, a negative pressure is formed. When the negative pressure inside the liquid pumping cylinder is less than the external atmospheric pressure, it prompts the disinfectant in the liquid storage tank to flow into the liquid pumping cylinder through the one-way flow pipe. The disinfectant in the liquid pumping cylinder flows into the nozzle and finally sprays out evenly from the nozzle, covering all the components of the first support plate to achieve comprehensive disinfection.

[0029] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Embodiment: A clamping device for orthopedic nursing, as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown in the figure, it includes a first support plate 1, an L-shaped plate 2, a fixing plate 3, a first screw 4, a support mechanism 5, an arc-shaped ring plate 6, a female buckle 7, a male buckle 8, and a pushing mechanism 9. On the front parts of the left and right sides of the first support plate 1, L-shaped plates 2 are connected. On the horizontal part of the L-shaped plate 2, a first screw 4 is screwed. On the inner side of the vertical part of the L-shaped plate 2, a fixing plate 3 is slidably connected. The bottom end of the first screw 4 is rotatably connected to the top of the fixing plate 3. The medical staff rotates the first screw 4 to drive the fixing plate 3 to move, so that the fixing plate 3 fits against the edge of the hospital bed, facilitating the fixation of the first support plate 1 on the hospital bed. On the first support plate 1, there is a support mechanism 5 for fixing the arc-shaped ring plate 6. The arc-shaped ring plate 6 is used to limit the patient's leg. There are two arc-shaped ring plates 6. On the two arc-shaped ring plates 6, a plurality of symmetrically distributed ventilation holes 61 are provided to facilitate the ventilation of the patient's injured leg. On the front sides of the two arc-shaped ring plates 6, female buckles 7 are connected at intervals through elastic bands. On the rear sides of the two arc-shaped ring plates 6, male buckles 8 are connected at intervals through elastic bands. The male buckle 8 is engaged with the female buckle 7. Through the cooperation of the male buckle 8 and the female buckle 7, the two arc-shaped ring plates 6 can be fixed on the patient's injured leg. On the upper part of the first support plate 1, there is a pushing mechanism 9 for slightly bending the patient's knee.

[0031] As Figures 2 - 4 shown, the support mechanism 5 includes an L-shaped threaded sleeve 51, a cylindrical sleeve 52, a second support plate 54, a torsion spring 55, and a fixed threaded sleeve 56. On the top of the first support plate 1, two fixed threaded sleeves 56 are symmetrically arranged on the left and right. The upper part of the fixed threaded sleeve 56 is conical. The cylindrical sleeve 52 is sleeved on the fixed threaded sleeve 56, facilitating the fixation of the L-shaped threaded sleeve 51 and the second support plate 54 on the fixed threaded sleeve 56. On the top of the fixed threaded sleeve 56, an L-shaped threaded sleeve 51 is sleeved. The internal thread of the cylindrical sleeve 52 is screwed with the external threads of the fixed threaded sleeve 56 and the L-shaped threaded sleeve 51. The horizontal ends of the L-shaped threaded sleeve 51 are rotatably connected to the second support plate 54. A torsion spring 55 is connected between the second support plate 54 and the L-shaped threaded sleeve 51. An arc-shaped ring plate 6 is arranged between the two second support plates 54 on the same side, which is used to support the patient's injured leg to provide uniform support force and avoid excessive local stress.

[0032] As Figure 4As shown, the pushing mechanism 9 includes a dual-axis motor 91, a second screw 92, a guide frame 93, a sliding shaft 94, a connecting rod 95, a guide rod 96, a cushion support 97, and a sliding rod 98. A dual-axis motor 91 is installed in the middle of the upper part of the first support plate 1. Rotating shafts are symmetrically connected to the left and right in the middle of the first support plate 1, and the rotating shafts are connected to the output shafts of the dual-axis motor 91. Second screws 92 are connected to the mutually remote ends of the two rotating shafts. Guide frames 93 are symmetrically connected to the front and back of the top of the first support plate 1 with respect to the second screws 92. A sliding shaft 94 is slidably connected between the two guide frames 93 on the same side. During the movement of the sliding shaft 94, the guide frame 93 plays a guiding role. A nut is embedded in the middle of the sliding shaft 94, and the sliding shaft 94 is screwed with the second screw 92 through the nut. Connecting rods 95 are rotatably connected to both ends of the sliding shaft 94. Guide rods 96 are symmetrically and vertically connected to the front and back of the middle of the top of the first support plate 1. A sliding rod 98 is slidably connected to the guide rod 96. A cushion support 97 is connected between the two sliding rods 98. The cushion support 97 is designed to be semi-circular. This shape can closely fit the natural curve of the back of the patient's knee, ensuring that the cushion support 97 can comfortably support the patient's knee during use, reducing the discomfort that may occur under long-term contact, and at the same time providing the necessary stability and protection. The other side of the connecting rod 95 is rotatably connected to the adjacent sliding rod 98.

[0033] As Figure 5 shown, a reinforcing mechanism 10 is further included. The reinforcing mechanisms 10 are arranged inside both of the two arc-shaped ring plates 6. The reinforcing mechanism 10 includes an arc-shaped air cushion 101, an air inlet pipe 102, a sealing cover 103, and an air outlet valve 104. Arc-shaped air cushions 101 are arranged inside both of the two arc-shaped ring plates 6. The arc-shaped air cushions 101 are made of polymer materials and have good elasticity and durability. A plurality of symmetrically distributed air holes 61 are also provided on the two arc-shaped air cushions 101 to improve the ventilation and comfort of the arc-shaped air cushions 101. Air inlet pipes 102 are connected to the front sides of the two arc-shaped air cushions 101, facilitating the delivery of gas into the arc-shaped air cushions 101 through the air inlet pipes 102. Sealing covers 103 are rotatably connected to the air inlet pipes 102 to ensure the airtightness inside the arc-shaped air cushions 101. Air outlet valves 104 are installed on the front sides of the two arc-shaped air cushions 101. The air outlet valves 104 are located on the right side of the air inlet pipes 102 and are used to adjust the air pressure inside the arc-shaped air cushions 101 to ensure the safe and comfortable use of the arc-shaped air cushions 101.

[0034] As Figure 6 and Figure 7As shown in the figure, it further includes a storage mechanism 11. The storage mechanism 11 is arranged below the first support plate 1. The storage mechanism 11 includes a storage box 111, a rotating frame 112, a magnetic suction door 113, a magnetic strip 114, a wedge block 115 and an elastic member I 116. The rotating frame 112 is rotatably connected to the front side of the storage box 111. The rotating frame 112 is bolted to the first support plate 1. The magnetic strip 114 is connected to the front side of the storage box 111. The magnetic strip 114 is connected to the magnetic suction door 113 on the front side. The magnetic suction door 113 is magnetically connected to the magnetic strip 114. The wedge block 115 is slidably connected to the left side of the storage box 111, which can fix the first support plate 1 when the first support plate 1 is stored. An elastic member I 116 is connected between the wedge block 115 and the storage box 111.

[0035] As Figures 7 - 10 shown in the figure, it further includes a disinfection mechanism 12. The disinfection mechanism 12 is arranged inside the storage box 111. The disinfection mechanism 12 includes a liquid storage tank 121, a one-way flow pipe 1211, a liquid pumping cylinder 122, an elastic member II 1221, a piston plate 1222, a spray head 123, a pull rope 124, a guide rod 125, a sliding frame 1251, an elastic member III 126 and a rotating plate 127. The liquid storage tank 121 is arranged on the rear inner side of the storage box 111 for storing the disinfectant. The liquid pumping cylinders 122 are symmetrically connected to the left and right on the rear inner side of the storage box 111. When the negative pressure inside the liquid pumping cylinder 122 is less than the external atmospheric pressure, it causes the disinfectant in the liquid storage tank 121 to flow into the liquid pumping cylinder 122 through the one-way flow pipe 1211. One-way flow pipes 1211 are connected between the two liquid pumping cylinders 122 and the liquid storage tank 121. The piston plate 1222 is slidably connected inside the liquid pumping cylinder 122. Since the movement of the piston plate 1222 causes the internal volume of the liquid pumping cylinder 122 to increase and the air pressure to decrease, a negative pressure is formed. An elastic member II 1221 is connected between the piston plate 1222 and the liquid pumping cylinder 122. A spray head 123 is arranged between the two liquid pumping cylinders 122, which can spray the disinfectant onto the first support plate 1 and all components thereon, facilitating the disinfection of the first support plate 1 and all components thereon. Two groups of guide rods 125 are symmetrically connected to the left and right on the rear inner side of the storage box 111. A sliding frame 1251 is slidably connected between the two guide rods 125 in the same group. The pull rope 124 is connected to the front side of the piston plate 1222. The pull rope 124 slidably passes through the liquid pumping cylinder 122 and is fixedly connected to the sliding frame 1251. The rotating plate 127 is rotatably connected to the sliding frame 1251. An elastic member III 126 is connected between the rotating plate 127 and the sliding frame 1251.

[0036] When it is necessary to limit the patient's leg using this device, the medical staff first squeeze the female buckle 7 to separate the female buckle 7 from the male buckle 8, facilitating the removal of the male buckle 8. Repeat the above operation to ensure that all male buckles 8 are in the open state, which is convenient for placing on the injured leg of the patient. Subsequently, the medical staff slowly lift the injured leg of the patient to an appropriate height, and then place the arc-shaped ring plate 6 on the back of the patient's injured thigh. After ensuring that the position of the arc-shaped ring plate 6 is correct, the medical staff then buckle the male buckle 8 onto the corresponding female buckle 7. Repeat the operation of buckling the male buckle 8 onto the female buckle 7 to ensure that all male buckles 8 are correctly buckled onto the corresponding female buckles 7, facilitating the fixation of the arc-shaped ring plate 6 on the back of the patient's injured thigh. Repeat the above operation to fix another arc-shaped ring plate 6 on the back of the patient's injured calf. Then, through the connection of the male buckle 8 and the female buckle 7 between the two arc-shaped ring plates 6, ensure that the two arc-shaped ring plates 6 are connected. Then, slowly place the patient's leg on the hospital bed. When it is necessary to support the injured leg of the patient during the patient's bed rest, the medical staff place the storage box 111 at the edge of the hospital bed, and then pull the magnetic door 113 outward to make the magnetic door 113 separate from the magnetic strip 114. Subsequently, the medical staff slowly lift the injured leg of the patient to an appropriate height. Since the rotating frame 112 is fixed to the first support plate 1 by bolts, then pull the first support plate 1 to drive the rotating frame 112 to rotate along the storage box 111. During the rotation of the first support plate 1, the first support plate 1 contacts the rotating plate 127 and squeezes the rotating plate 127, causing the rotating plate 127 to rotate along the sliding frame 1251, and the elastic member III 126 deforms. At the same time as the first support plate 1 rotates, the first support plate 1 contacts the wedge-shaped block 115 and squeezes the wedge-shaped block 115, causing the wedge-shaped block 115 to move outward along the storage box 111, and the elastic member I 116 is compressed. Then continue to pull the first support plate 1 to drive the rotating frame 112 to rotate along the storage box 111. When the first support plate 1 rotates to the hospital bed, stop rotating the first support plate 1. At the same time, the L-shaped plate 2 contacts the hospital bed and fits on it. Then rotate the first screw rod 4 to drive the fixing plate 3 to move upward. The fixing plate 3 moves and contacts the hospital bed, and fits with the edge of the hospital bed, facilitating the fixation of the first support plate 1 on the hospital bed. At this time, the rotating plate 127 is no longer squeezed. Under the reset action of the elastic member III 126, the rotating plate 127 rotates reversely along the sliding frame 1251 to the initial position. At the same time, the wedge-shaped block 115 is no longer squeezed. Under the reset action of the elastic member I 116, the wedge-shaped block 115 moves inward along the storage box 111 until the wedge-shaped block 115 moves to the initial position. Then place the magnetic door 113 on the magnetic strip 114. Using the magnetic force, an attractive force is generated between the magnetic door 113 and the magnetic strip 114 to ensure that the magnetic door 113 is tightly closed. Then install the fixed threaded sleeve 56 on the first support plate 1. After the installation of the fixed threaded sleeve 56 is completed, place the cylindrical sleeve 52 on the fixed threaded sleeve 56.Subsequently, insert the L-shaped threaded sleeve 51 and the second support plate 54 onto the fixed threaded sleeve 56. After inserting the L-shaped threaded sleeve 51 and the second support plate 54, pull the cylindrical sleeve 52 upward along the fixed threaded sleeve 56 until the cylindrical sleeve 52 moves onto the threaded groove of the fixed threaded sleeve 56, and then rotate the cylindrical sleeve 52 along the threaded grooves of the fixed threaded sleeve 56 and the L-shaped threaded sleeve 51. When the cylindrical sleeve 52 rotates to an appropriate position, release the cylindrical sleeve 52. Repeat the above operations to ensure that all the L-shaped threaded sleeves 51 and the second support plates 54 are installed. Then, the medical staff slowly place the injured leg of the patient between the four second support plates 54. After the injured leg of the patient is placed, make the four second support plates 54 closely fit with the two arc-shaped ring plates 6 to provide uniform supporting force, avoid excessive local stress, and ensure the comfort of the injured leg of the patient. When the patient feels uncomfortable, the medical staff pull the sealing cover 103 to rotate and open it, then connect the air filling pipe of the air inflator to the air inlet pipe 102. After ensuring its stable connection, turn on the air inflator so that the gas enters the air inlet pipe 102 through the air filling pipe and is then transported from the air inlet pipe 102 to the arc-shaped air cushion 101, prompting the arc-shaped air cushion 101 to gradually expand until the arc-shaped air cushion 101 reaches an appropriate size. After the inflation is completed, turn off the air inflator and disconnect the air filling pipe to prevent excessive gas filling or leakage. Then, pull the sealing cover 103 to rotate in the reverse direction and cover it back onto the air inlet pipe 102 to ensure the airtightness of the arc-shaped air cushion 101 and avoid accidental loss of gas during the use of the arc-shaped air cushion 101. This helps to uniformly apply a supporting force to the patient's leg, reduce local pressure, and also helps to prevent poor blood circulation that may be caused by long-term bed rest. If the medical staff observes red spots or indentations on the patient's leg or the patient feels uncomfortable, the medical staff open the air outlet valve 104 so that the gas in the arc-shaped air cushion 101 is discharged through the air outlet pipe, which can release some gas to adjust the hardness of the arc-shaped air cushion 101. After the hardness of the arc-shaped air cushion 101 is adjusted to an appropriate state, close the air outlet valve 104 to ensure that the gas in the arc-shaped air cushion 101 no longer leaks. To help the patient slightly bend the knee, prevent deep vein thrombosis, and promote blood circulation in the lower extremities, the medical staff start the dual-axis motor 91. The output shafts on both sides of the dual-axis motor 91 drive the rotating shaft to rotate, the rotating shaft drives the second screw rod 92 to rotate, and the second screw rod 92 drives the sliding shaft 94 to move inward along the guide frame 93. During the movement of the sliding shaft 94, the connecting rod 95 rotates along the sliding shaft 94. While the connecting rod 95 rotates, the other side of the connecting rod 95 drives the sliding rod 98 and the cushion support 97 to move upward along the guide rod 96. The cushion support 97 moves to fit with the back of the patient's knee and drives it upward. When the patient's knee is slightly bent, turn off the dual-axis motor 91. During the process of the patient's knee being slightly bent, the injured thigh of the patient drives the arc-shaped ring plate 6 and the second support plate 54 to rotate along the L-shaped threaded sleeve 51, and the torsion spring 55 deforms. At the same time,The injured calf of the patient drives another arc-shaped ring plate 6 and the second support plate 54 thereon to rotate along the corresponding L-shaped threaded sleeve 51, and another torsion spring 55 deforms, facilitating the prevention of deep vein thrombosis in the injured leg of the patient and promoting blood circulation in the injured leg of the patient. When the patient needs to get out of bed for rehabilitation, the medical staff pulls the magnetic door 113 open again, causing the magnetic door 113 to disengage from the magnetic strip 114. The medical staff starts the dual-axis motor 91 again, causing the dual-axis motor 91 to operate and repeat the above opposite operations, facilitating the cushion holder 97 to slowly lower the back of the patient's knee until the patient's knee is in an unbent state, then the dual-axis motor 91 is turned off. Subsequently, the medical staff lifts the injured leg of the patient. When the injured leg of the patient is lifted to an appropriate height, the first screw rod 4 is rotated in the reverse direction. The first screw rod 4 drives the fixed plate 3 to move downward. When the fixed plate 3 moves to the initial position, the fixed plate 3 disengages from the edge of the hospital bed. Subsequently, the first screw rod 4 is released, and the first support plate 1 is pulled to drive the rotating frame 112 to rotate in the reverse direction along the storage box 111. During the reverse rotation of the first support plate 1, the first support plate 1 drives all the components thereon to rotate in the reverse direction. When the first support plate 1 rotates in the reverse direction and contacts the rotating plate 127, it pushes the rotating plate 127 to drive the sliding frame 1251 to move backward along the guide rod 125. The movement of the sliding frame 1251 drives the pull rope 124 to move forward along the liquid extraction cylinder 122. The movement of the pull rope 124 drives the piston plate 1222 to move forward along the liquid extraction cylinder 122, and the elastic member II 1221 is compressed. Since the movement of the piston plate 1222 causes the internal volume of the liquid extraction cylinder 122 to increase and the air pressure to decrease, a negative pressure is formed. When the negative pressure inside the liquid extraction cylinder 122 is less than the external atmospheric pressure, it prompts the disinfectant in the liquid storage tank 121 to flow into the liquid extraction cylinder 122 through the one-way flow pipe 1211. The disinfectant in the liquid extraction cylinder 122 flows into the nozzle 123 and finally sprays out evenly from the nozzle 123, covering all the components of the first support plate 1, achieving comprehensive disinfection and facilitating subsequent use. While the first support plate 1 rotates in the reverse direction, the first support plate 1 contacts the wedge-shaped block 115 and squeezes the wedge-shaped block 115 again, causing the wedge-shaped block 115 to move outward along the storage box 111. When the first support plate 1 rotates in the reverse direction to the initial position, the first support plate 1 is released. When the first support plate 1 no longer contacts the rotating plate 127, under the reset action of the elastic member II 1221, the piston plate 1222 moves backward along the liquid extraction cylinder 122, thereby driving the pull rope 124 to move backward along the liquid extraction cylinder 122. The movement of the pull rope 124 drives the sliding frame 1251 and the rotating plate 127 to move forward along the guide rod 125 until the sliding frame 1251 and the rotating plate 127 move to the initial position. At the same time, the first support plate 1 no longer squeezes the wedge-shaped block 115, and under the reset action of the elastic member I 116, the wedge-shaped block 115 moves inward along the storage box 111 to the initial position, facilitating the fixation of the first support plate 1. Then the magnetic door 113 is placed on the magnetic strip 114 again, using the magnetic force,An attractive force is generated between the magnetic door 113 and the magnetic strip 114 to ensure that the magnetic door 113 closes tightly again. Then, the injured leg of the patient is slowly placed on the hospital bed, and then the medical staff or family members assist the patient to get out of bed for rehabilitation training.
