Description

Technical Field

[0001] This invention relates to the field of orthopedic traction technology, specifically to a traction device for orthopedic nursing. Background Technology

[0002] Traction devices for orthopedic nursing are key auxiliary equipment in orthopedic clinical nursing. Their core function is to reduce, fix and maintain the position of the affected limb in patients with fractures, dislocations or joint deformities by applying continuous and controllable traction force, while relieving local soft tissue pressure and creating a stable environment for bone healing.

[0003] Existing orthopedic traction devices often involve multiple wrappings with fixed straps before suspension traction, or the use of fixed supports for traction. This makes it difficult to distribute the force evenly on the legs. Furthermore, due to differences in leg thickness and curvature among patients, prolonged traction treatment can easily cause fatigue. Repeated adjustments can lead to secondary injuries. Additionally, during prolonged lying traction, the different force points on the waist, hips, and shoulders can easily cause long-term compression, leading to numbness, pain, and even pressure sores.

[0004] To address the above issues, a traction device for orthopedic nursing is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a traction device for orthopedic nursing. By using this device, the problems mentioned above are solved, such as the difficulty in uniform force distribution on the leg, the differences in leg thickness and curvature among patients, the tendency for prolonged traction treatment to cause fatigue, and the risk of secondary injury to patients due to repeated adjustments.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a traction device for orthopedic nursing, comprising a nursing bed and an electric push cylinder installed in the upper middle part of the nursing bed, wherein a rotating bed plate is rotatably mounted on the top of the electric push cylinder, a fixing frame is fixedly installed on one side above the rotating bed plate, and two sets of adjusting horizontal plates are slidably arranged in the upper middle part of the fixing frame, a winch is installed on both sides of the lower surface of the two sets of adjusting horizontal plates, and a lifting rope is connected below the output end of the winch, and a fixing mechanism is connected to the bottom of the lifting rope, wherein a pressure sensor is provided inside the fixing mechanism;

[0007] The surface of the rotating bed plate is provided with several sets of support mechanisms, and each set of support mechanisms is equipped with a pressure sensor II inside. The inside of each support mechanism is provided with a loosening mechanism on both sides.

[0008] Furthermore, the fixing mechanism includes a wrapping cover connected to the bottom of the lifting rope. The inner surface of the wrapping cover is provided with a plurality of fixing seats. A spring is fixed to the middle of the inner side of the fixing seat, and a lifting cylinder is fixed to the bottom end of the spring. The lifting cylinder is elastically slidably disposed with the fixing seat through the spring. The bottom of the lifting cylinder is fitted with a sleeve, and after the fixing seat is wrapped, it is fitted to the outer surface of the patient's leg with the sleeve. An electromagnetic seat is fixed inside the upper part of the fixing seat, and a strong magnetic block is fixed inside the lower part of the lifting cylinder.

[0009] Furthermore, a ball joint is rotatably mounted on one side of the fixed seat, and a connecting seat is provided on the other side of the ball joint. The connecting seat is another set of fixed seats, and the two fixed seats are connected in the horizontal direction by the ball joint. Thus, after the fixed seat is wrapped around the leg, the angle of the fixed seat in the horizontal direction can be adjusted in multiple directions according to the shape of the wrapped leg by using the ball joint. A filling cavity is provided on one side of the ball joint, and an electromagnetic coil is provided outside the filling cavity. The electromagnetic coil is installed inside the fixed seat.

[0010] Furthermore, a sliding rod is slidably provided on the side of the fixed seat, and one end of the sliding rod extends into the filling cavity. A spring is provided on the outer side of the sliding rod, and the two ends of the spring are fixedly connected to the fixed seat and the sliding rod respectively. The sliding rod is elastically connected to the fixed seat through the spring. A locking tooth block is fixed at the front end of the sliding rod, and a tooth plate is provided on the outer side of the locking tooth block. The tooth plate is fixed on the lifting cylinder.

[0011] Furthermore, the support mechanism includes a fixed seat two fixed inside the rotating bed plate, and a folding airbag is installed inside the lower part of the fixed seat two, and a spring three is installed inside the folding airbag. A solenoid valve one is installed in the lower middle part of the folding airbag, and an air supply pipe is connected to the input end of the solenoid valve one.

[0012] Furthermore, a support rod is fixed to the upper center of the folding airbag, and a mounting seat is rotatably mounted on the top of the support rod, with a fitting pad fixed to the top of the mounting seat.

[0013] Furthermore, the loosening mechanism includes two sets of solenoid valves connected to both sides above the folding airbag, and an inflation cylinder is connected to one side of each set of solenoid valves. The bottom of the inflation cylinder is fixedly connected to the top plate of the folding airbag. A piston rod is slidably installed inside the inflation cylinder, and a spring is provided in the middle of the outer side of the piston rod. The two ends of the spring are fixedly connected to the piston rod and the inflation cylinder, respectively.

[0014] Furthermore, a rotating seat is fixed to the top of the piston rod, a slider is rotatably mounted above the rotating seat, and a slide rail is slidably provided on the top of the slider, and the slide rail is fixedly connected to the mounting seat. An air release valve is connected to the other side of the air cylinder.

[0015] Furthermore, the folding airbag includes a venting pipe disposed inside the mounting base, and a pressure relief pipe is connected to the lower part of the venting pipe. The folding airbag is connected to the pressure relief pipe and the venting pipe.

[0016] Furthermore, the vent pipe has several reduced diameter sections in the middle of its inner side, and the inner diameter of the reduced diameter sections is smaller than the inner diameter of the vent pipe. Each set of reduced diameter sections is connected to a connecting pipe above it, and the connecting pipe is connected to the inside of the fitting pad.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the pressure applied to the thinner parts of the leg is insufficient, the magnetic force of the magnetic push mechanism can be adjusted accordingly with the control of the controller to increase the application force. Similarly, when the application force is too great on the thicker parts of the leg, reverse power can be applied to cause the application area to shrink and reduce the application force. At the same time, the tightness of the application can be adjusted according to the user's feedback, so that the force on the leg is more even and comfortable during traction. The multiple independently set application settings can also adapt to the differences in the thickness and contour of the patient's limbs, improving the adaptability of the device. At the same time, fixation and subsequent removal and adjustment are quick and convenient, reducing the possibility of secondary injury to the patient.

[0018] 2. This invention utilizes multiple independently set airbags. Airbags can be appropriately deflated in areas of high pressure such as the buttocks and shoulders, and appropriately inflated in the waist and sides of the body. This allows the independent airbags to distribute localized pressure, ensuring balanced force distribution across the body and adapting to its curves. This avoids poor blood circulation caused by single-point high pressure and creates a dynamic soothing effect on the patient's body contact surfaces, further improving blood circulation and enhancing tolerance to long-term treatment. Simultaneously, the dynamic separation and fit between the mattress and the body provides a massage effect, further reducing fatigue from long-term traction and improving the overall effectiveness of the device.

[0019] 3. Under the action of pressure difference, the gas in the mattress will be drawn into the constriction of the pipe and carried away by the airflow. This helps to remove the heat accumulated inside the mattress, thereby avoiding the problem of stuffiness and discomfort caused by prolonged contact with the mattress, and thus improving the performance of the device.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] To address the technical challenges of uneven force distribution on the legs, and the fact that prolonged traction therapy can easily lead to fatigue due to differences in leg thickness and curvature among patients, while repeated adjustments can cause secondary injury, [further details needed]. Figures 1-5 As shown, the following preferred technical solutions are provided: A traction device for orthopedic nursing includes a nursing bed 1 and an electric cylinder 2 installed at the upper center of the nursing bed 1. A rotating bed board 3 is rotatably mounted on the top of the electric cylinder 2. Using the electric cylinder 2, one end of the rotating bed board 3 can be tilted upwards, thereby allowing the nursing bed 1 to be adjusted to a flat lying position or a tilted sitting position to facilitate use during traction care. A fixing frame 4 is fixedly installed on one side of the upper part of the rotating bed board 3, and two sets of adjusting horizontal plates 5 are slidably installed at the upper center of the fixing frame 4. The two sets of adjusting horizontal plates 5 can slide between themselves and the fixing frame 4, and after sliding into place, they can be adjusted using an existing sliding sleeve structure. The adjusting plate 5 is tightened by using a screw to fix its position. A winch 6 is installed on both sides of the lower surface of both sets of adjusting plates 5, and a lifting rope 7 is connected to the lower output end of the winch 6. A fixing mechanism 8 is connected to the bottom of the lifting rope 7. After the adjusting plate 5 is moved to a suitable position and the patient's leg is wrapped and fixed using the fixing mechanism 8, the fixing mechanism 8 can be lifted to a suitable height using the winch 6 and the lifting rope 7, thereby achieving traction on the patient's leg. A pressure sensor 20 is installed on the inner side of the fixing mechanism 8.

[0024] The fixation mechanism 8 has multiple independent fitting structures arranged in a ring direction within its sleeve, and each fitting structure is equipped with a pressure sensor 20. After the sleeve wraps and fixes the patient's leg, the multiple fitting structures will adhere to the surface of the patient's leg. Due to differences in the thickness and curvature of the patient's leg, if multiple wrapping with fixation straps is used for suspension traction, or if a fixed bracket is used for traction, the force points on the leg are difficult to be even. Prolonged traction treatment can easily cause fatigue, and repeated adjustments can cause secondary injury to the patient and are inconvenient to operate. However, each fitting structure on the fixation mechanism 8 is equipped with a magnetic pushing mechanism, and each fitting structure works in conjunction with a pressure sensor. The device 20 can identify the pressure applied to the corresponding areas. When the pressure is insufficient on thinner areas of the leg, the magnetic force of the magnetic push mechanism can be adjusted in conjunction with the controller to increase the pressure. Similarly, when the pressure is too high on thicker areas of the leg, reverse power can be applied to shrink the area and reduce the pressure. The device can also adjust the tightness of the fit based on user feedback, making the force on the leg more even and comfortable during traction. The multiple independently set fits can also adapt to the differences in the thickness and contour of the patient's limbs, improving the device's adaptability. Furthermore, it is quick and easy to fix and remove for adjustment, reducing the possibility of secondary injury to the patient.

[0025] The surface of the rotating bed board 3 is equipped with several sets of support mechanisms 9, and each set of support mechanisms 9 has a pressure sensor 30 inside. Each set of support mechanisms 9 has an independent inflation mechanism, and the top of each set of support mechanisms 9 is a mattress structure. The inflation mechanism is supplied with air by an external air supply device and is controlled by a controller, allowing for independent inflation and deflation. This enables the mattress on top of each set of support mechanisms 9 to be adjusted in height independently. During prolonged lying traction, the different pressure points on the waist, hips, and shoulders can easily lead to long-term pressure, causing numbness, pain, and even pressure sores. In such cases, pressure... Force sensor 2 30 identifies the contact pressure on the mattress contact surface. It can appropriately deflate areas with high pressure, such as the buttocks and shoulders, and appropriately inflate areas such as the waist and sides of the body. This allows the independent airbags to distribute local pressure, making the force evenly distributed across the body and adapting to the body's curves. This avoids poor blood circulation caused by high pressure at a single point. At the same time, when the bed board 3 is rotated and tilted, the independent airbags can dynamically adjust the support height according to the traction needs, forming a support surface that conforms to the traction posture, preventing body displacement, ensuring the stability of traction, and improving the patient's tolerance to long-term treatment. The support mechanism 9 has loosening mechanisms 10 on both sides inside.

[0026] The loosening mechanism 10 is rotatably connected to the top of the mattress of the support mechanism 9, and the bottom of the mattress is also rotatably connected to the top support surface of the support mechanism 9. During normal inflation and adjustment of the support mechanism 9, the posture of the loosening mechanism 10 remains unchanged, ensuring stable support for the mattress. When each mattress support surface is used for an extended period, one side of the loosening mechanism 10 will inflate under the control of the controller. Under the pressure of the air, the loosening mechanism 10 will slowly lower one end of the mattress. After lowering, the air will be deflated, allowing one end of the mattress to return to its original position and remain stationary. Then, the other side will loosen. Mechanism 10 then inflates and deflates, causing the other end of the mattress to slowly descend and return to its original position. At this time, the sequential inflation and deflation of the two loosening mechanisms 10 on the left and right sides allows for dynamic adjustment of the mattress. As one end of the mattress moves down, it relaxes and maintains continuous contact with the body, thereby creating a dynamic soothing effect on the patient's body contact surface. This further improves blood circulation in the contact surface, thereby increasing tolerance to long-term treatment. At the same time, the dynamic separation and contact between the mattress and the body also provides a massage effect, further reducing fatigue from long-term traction and improving the effectiveness of the device.

[0027] Simultaneously, when the airbags of the support mechanism 9 deflate, pressurized airflow flows through the bottom pipes of the mattress and exits from both ends. The pipes have a narrowing section, and the narrowing section is connected to the interior of the mattress via a conduit. The mattress is made of breathable foam. When the airflow passes through the narrowing section, the channel narrows, the airflow velocity increases significantly, and the pressure at this point decreases dramatically. Meanwhile, the pressure in the conduit area leading into the mattress is relatively high. Under the pressure difference, the air in the mattress is drawn into the narrowing section of the pipe and carried away by the airflow. This helps to remove the heat accumulated inside the mattress, thus avoiding the problem of stuffiness and discomfort caused by prolonged contact with the mattress, and improving the effectiveness of the device.

[0028] The fixing mechanism 8 includes a wrapping cover 81 connected to the bottom of the lifting rope 7. The wrapping cover 81 is a square surface with Velcro. After the edges are rolled up and glued with Velcro, it can form a cylindrical shape, so that the leg can be wrapped and fixed when the patient is using traction. The inner surface of the wrapping cover 81 is provided with several fixing seats 82. After the wrapping cover 81 is wrapped, the multiple sets of fixing seats 82 wrap around the outside of the leg. A spring 83 is fixed in the middle of the inner side of the fixing seat 82, and a lifting cylinder 84 is fixed at the bottom end of the spring 83. The lifting cylinder 84 is elastically slidably set with the fixing seat 82 through the spring 83.

[0029] A fitting sleeve 85 is installed at the bottom of the lifting cylinder 84. After the fixing seat 82 is wrapped around it, the fitting sleeve 85 is used to fit the outer surface of the patient's leg. A pressure sensor 20 is set between the fitting sleeve 85 and the lifting cylinder 84. An electromagnetic seat 86 is fixed inside the upper part of the fixing seat 82, and a strong magnet 87 is fixed inside the lower part of the lifting cylinder 84. After the fitting sleeve 85 is in place, the pressure sensor 20 can identify the fitting pressure of the corresponding fitting area. When the fitting pressure is insufficient in a thinner part of the leg, the current of the electromagnetic seat 86 can be increased accordingly with the control of the controller. This causes the electromagnetic seat 86 and the strong magnet 87 to generate the same magnetic force and repel each other. Under the magnetic force, the lifting cylinder 84 and the fitting sleeve 85 stretch the spring 83 and move away from the fixing seat 82. This increases the adhesion of the fitting sleeve 85 to the leg. Similarly, when the adhesion is too strong on thicker parts of the leg, the electromagnetic base 86 can be energized in the opposite direction, causing the electromagnetic base 86 and the strong magnet 87 to generate opposite attraction forces, causing the fitting sleeve 85 to contract and reduce the adhesion. At the same time, the tightness of the fitting sleeve 85 can be adjusted according to the user's feedback, making the force on the leg more even and comfortable during traction. The independent fitting of multiple sets of fixing bases 82 and fitting sleeves 85 can also adapt to the differences in the thickness and contour of the patient's limbs, improving the adaptability of the device. At the same time, the compression fixation achieved by electromagnetic force makes it quicker and more convenient to remove and adjust later, avoiding the problem of secondary injury to the patient that can be easily caused by using bandages or fixation brackets.

[0030] A ball joint head 88 is rotatably mounted on one side of the fixed base 82, and a sliding seal is provided between the ball joint head 88 and the fixed base 82. A connecting seat 89 is provided on the other side of the ball joint head 88. The connecting seat 89 and the fixed base 82 have the same composition and connection relationship, and are connected horizontally by the ball joint head 88. Therefore, after the fixed base 82 is wrapped around the leg, the angle of the horizontal fixed base 82 can be adjusted in multiple directions according to the shape of the wrapped leg using the ball joint head 88. A filling cavity 810 is provided on one side of the ball joint head 88, and the interior of the filling cavity 810 is filled with magnetorheological fluid. The exterior of the filling cavity 810 is... An electromagnetic coil 811 is installed inside the fixing base 82. An insulating isolation plate is provided between the electromagnetic coil 811 and the electromagnetic base 86. After the curvature of the wrapping is adjusted by the ball joint head 88 and the pressure of the fitting sleeve 85 is adjusted by the fixing base 82, the controller controls the electromagnetic coil 811 to be energized. Under the action of magnetic force, the magnetorheological fluid in the filling cavity 810 will solidify, thereby fixing the ball joint head 88. This allows the fixing base 82 and the fitting sleeve 85 to adapt to the curvature of the patient's leg shape and achieve shape fixation. While ensuring traction adaptability, it also helps to further ensure the uniform force on the fitting sleeve 85.

[0031] A sliding rod 812 is slidably provided on the side of the fixed base 82, and one end of the sliding rod 812 extends into the filling cavity 810. A spring 813 is provided on the outer side of the sliding rod 812, and the two ends of the spring 813 are fixedly connected to the fixed base 82 and the sliding rod 812 respectively. The sliding rod 812 is elastically connected to the fixed base 82 through the spring 813. A locking tooth block 814 is fixed at the front end of the sliding rod 812, and a toothed plate 815 is provided on the outer side of the locking tooth block 814. The toothed plate 815 is fixed on the lifting cylinder 84. The locking tooth block 814 and the toothed plate 815 mesh with each other, and both are arc surfaces.

[0032] When the lifting cylinder 84 rises or falls under the action of magnetic force to adjust the fitting sleeve 85, the squeezing force of the lifting cylinder 84 and the toothed plate 815 will squeeze the engaging tooth block 814 and the sliding rod 812 to compress the second spring 813 and move it. The lifting cylinder 84 has a multi-stage adjustment mechanism, allowing it to be smoothly adjusted up and down. After adjustment, when the engaging tooth block 814 engages with the toothed plate 815 under the rebound of the second spring 813, the electromagnetic coil 811 is energized, causing the magnetorheological fluid in the filling cavity 810 to solidify. The solidified magnetorheological fluid can also affect the sliding rod 81. The tail end of 2 is fixed and restricted, so that the sliding rod 812 loses its elastic movement ability, allowing the lifting cylinder 84 to be locked in the fixed seat 82, thereby fixing the lifting cylinder 84 in the adjusted position to ensure the stability of the fitting sleeve 85 against the leg. At the same time, after the lifting cylinder 84 is fixed, the electromagnetic seat 86 can be de-energized to avoid the waste of power and interference caused by continuous power supply to maintain the position. Also, when the lifting cylinder 84 needs to be adjusted, the electromagnetic coil 811 is de-energized first, and then the power is restored after the adjustment is completed to maintain the fixed position.

[0033] To address the technical challenges of prolonged lying traction, where varying pressure points on the lower back, hips, and shoulders can lead to long-term compression, causing numbness, pain, and even pressure sores, such as... Figure 1 as well as Figures 6-8 As shown, the following preferred technical solutions are provided: The support mechanism 9 includes a fixed seat 2 91 fixed inside the rotating bed plate 3, and a folding airbag 92 is installed inside the lower part of the fixed seat 2 91. A spring 3 93 is installed inside the folding airbag 92. A solenoid valve 1 94 is installed in the lower middle part of the folding airbag 92. The input end of the solenoid valve 1 94 is connected to an air supply pipe 95. The air supply pipe 95 is supplied with air by an external air supply device. Under the control of the controller, the solenoid valve 1 94 can inflate the folding airbag 92. The folding airbag 92 has air pressure inside in the initial state. At the same time, the inflation and deflation of each set of folding airbags 92 are set independently.

[0034] A support rod 96 is fixed to the upper center of the folding airbag 92. A pressure sensor 30 is positioned between the support rod 96 and the top plate of the folding airbag 92. A mounting base 97 is rotatably mounted on the top of the support rod 96, and a contact pad 98 is fixed to the top of the mounting base 97. The pressure sensor 30 identifies the contact pressure on the contact surface of the contact pad 98. In conjunction with the controller, the folding airbag 92 can be appropriately deflated in areas with high pressure, such as the buttocks and shoulders, and appropriately inflated in areas such as the waist and the sides of the body, thus dispersing the pressure of the individual folding airbags 92. The pressure on different parts of the body ensures balanced force distribution, adapting to the body's curves and preventing poor blood circulation caused by high pressure at a single point. Simultaneously, when the bed board 3 is tilted, the independent folding airbag 92 can dynamically adjust its support height according to traction needs, forming a support surface that conforms to the traction posture, preventing body displacement, ensuring traction stability, and improving the patient's tolerance for long-term treatment. Furthermore, the airbag's inflation and deflation structure is more compact, making it more suitable for large-area dynamic adjustment of support, and the airbag itself has a certain degree of elastic cushioning, which can improve user comfort.

[0035] The loosening mechanism 10 includes two sets of solenoid valves 101 connected to the upper sides of the folding airbag 92, and an inflation cylinder 102 is connected to one side of each set of solenoid valves 101. The bottom of the inflation cylinder 102 is fixedly connected to the top plate of the folding airbag 92. Under the control of the controller, the solenoid valves 101 are opened, so that gas can also be filled into the inflation cylinder 102 when the folding airbag 92 is inflated. A piston rod 103 is slidably installed inside the inflation cylinder 102, and a spring 104 is provided in the middle of the outer side of the piston rod 103. The two ends of the spring 104 are fixedly connected to the piston rod 103 and the inflation cylinder 102 respectively. When the inflation cylinder 102 is inflated, the spring 104 will be stretched under the action of air pressure, causing the piston rod 103 to move down.

[0036] A rotating seat 105 is fixed to the top of the piston rod 103. A slider 108 is rotatably mounted above the rotating seat 105, and a slide rail 106 is slidably provided on the top of the slider 108. The slide rail 106 is fixedly connected to the mounting base 97. An air release valve 107 is connected to the top of the other side of the air cylinder 102. The air release valve 107 is a solenoid valve. When the air cylinder 102 is inflated, causing the piston rod 103 to move down, the piston rod 103 can pull one end of the mounting base 97 down using the rotating seat 105, the slider 108 and the slide rail 106. When the folding airbag 92 is being used for normal inflation adjustment support, the solenoid valve 101 is not open, and the position of the piston rod 103 remains unchanged, so that the fitting pad 98 maintains stable support.

[0037] When the support surface of each set of bonding pads 98 is used for a long time, one side of the air cylinder 102 will inflate under the control of the controller, while the other side air cylinder 102 remains unchanged. Under the action of air pressure, the piston rod 103 will slowly lower one end of the bonding pad 98. After lowering, the controller will close the solenoid valve 101 and release the air through the deflation valve 107. This will cause the piston rod 103 to move back to its original position under the contraction of the spring 104, allowing one end of the bonding pad 98 to return to its original position and remain stationary. Then, the other side air cylinder 102 will inflate and deflate again, allowing... The other end of the pad 98 also slowly descends and returns to its original position. At this time, the left and right sets of air cylinders 102 are inflated and deflated in sequence, so that the dynamic adjustment of the pad 98 can relax the continuous contact with the body when one end of the pad 98 moves down, thereby creating a dynamic soothing effect on the patient's body contact surface, further improving the blood circulation effect of the contact surface, thereby improving the tolerance of long-term treatment. At the same time, the dynamic separation and contact between the pad 98 and the body can also have a massage effect, further reducing the fatigue of long-term traction and improving the effectiveness of the device.

[0038] To address the technical problem of patients feeling hot and uncomfortable due to prolonged contact with the mattress during traction, such as... Figure 1 as well as Figures 7-10 As shown, the following preferred technical solutions are provided: The folding airbag 92 includes a vent pipe 922 disposed inside the mounting base 97, and a pressure relief pipe 921 is connected to the lower part of the vent pipe 922. The folding airbag 92 is connected to the pressure relief pipe 921 and the vent pipe 922. The pressure relief pipe 921 is connected to the folding airbag 92 by a solenoid valve. When the folding airbag 92 deflates, the solenoid valve opens, allowing gas to flow into the vent pipe 922.

[0039] The vent tube 922 has several reduced-diameter sections 923 on its inner side, and the inner diameter of each reduced-diameter section 923 is smaller than the inner diameter of the vent tube 922. Each set of reduced-diameter sections 923 is connected to a connecting pipe 924 above it, and the connecting pipe 924 is connected to the inside of the fitting pad 98. When the folded airbag 92 is deflated using the solenoid valve and the pressure relief pipe 921, a pressurized airflow flows through the vent tube 922 and is finally discharged directly from the end of the vent tube 922. When the airflow passes through the reduced-diameter section 923... When the channel narrows, the airflow velocity increases significantly, and the pressure at this point decreases dramatically. Meanwhile, the pressure in the area of ​​the connecting pipe 924 inside the bonding pad 98 is relatively high. Under the influence of the pressure difference, the gas in the bonding pad 98 is drawn into the narrowed section 923 of the pipe and carried away by the airflow in the vent pipe 922. This helps to remove the heat accumulated inside the bonding pad 98, thus avoiding the problem of stuffiness and discomfort caused by prolonged contact with the mattress, and thereby improving the effectiveness of the device.
