Description

Technical Field

[0001] The invention relates to the technical field of hot compress equipment, in particular to a rehabilitation therapy auxiliary appliance. Background Art

[0002] Hot compress therapy is a common physical therapy that provides heat to relax tense muscles, relieve inflammation, and improve joint flexibility. This therapy can help patients relieve pain and discomfort, and is an important part of the rehabilitation treatment of rheumatoid arthritis. Usually, the temperature of the hot compress is between 40 and 50 degrees Celsius, and the hot compress time is generally 15 to 20 minutes, and hot compress is required several times a day. The current methods of hot compress are to use hot water bottles, hot towels or electric heating pads.

[0003] Hot compress appliances such as hot water bottles and hot towels lack a fixed structure and are simply placed on the patient. The hot compress time is long and the patient cannot stay still for a long time. Therefore, the hot water bottle and hot towel are easily dropped and displaced due to body activities, which is not conducive to the stable hot compress. Although some electric heating pads have fixed ropes to fix the position, the tightness of the binding cannot be guaranteed, and it is easy to be too tight or too loose. Too tight binding will lead to poor blood circulation in the legs, which has an adverse effect on the patient. Too loose binding will easily fall off and cannot achieve the purpose of fixation. Even if the fixed tightness is appropriate, its tightness is determined after the binding is completed, and it cannot be automatically adjusted according to the patient's activities. For patients who need hot compress on their joints, when the patient's joints move, such as when the knee joint is bent, the change in muscle shape and the deformation of the heating pad will cause the patient's binding force to increase, causing discomfort to the patient, and will also partially stretch the binding ropes or straps, which will easily slip off when walking. Therefore, when applying hot compress, they can only stay in bed and keep their limbs still to ensure the effect of the hot compress. If they get up and move, the risk of falling off will increase. For patients who have been bedridden for a long time, staying in bed has no effect, but for patients who can move around, requiring them to stay in bed every time a hot compress is required, which is less practical. In addition, this will increase the requirements for environmental factors, and the hot compress is subject to more restrictions, which cannot meet the patient's daily hot compress requirements. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a rehabilitation therapy auxiliary device, which effectively solves the problem that the existing device is inconvenient to automatically adjust the binding force according to the patient's activities.

[0005] The technical solution is that the present invention includes a carbon nanotube heating pad, a thermal insulation pad is fixed to the left end of the carbon nanotube heating pad, three straps distributed in the front-to-back direction are fixed to the left end of the thermal insulation pad, an insulating airbag is fixed to the lower end of the carbon nanotube heating pad and the thermal insulation pad, a plurality of air holes are provided on the thermal insulation airbag, a heat dissipation pad is fixed to the lower end of the thermal insulation airbag, a skin-friendly layer is fixed to the lower end of the heat dissipation pad, and a control box is provided above the thermal insulation pad.

[0006] A concave booster barrel with a notch facing forward is fixed in the regulating box, and extrusion blocks are slidably connected to the left and right openings of the booster barrel respectively. The rear end surface of the extrusion block and the booster barrel is filled with transmission oil, and the contact area between the left extrusion block and the transmission oil is larger than the contact area between the right extrusion block and the transmission oil. The right extrusion block moves back and forth with the change of the pressure in the insulation airbag. When the pressure in the insulation airbag increases, the speed at which the right extrusion block moves backward is lower than the speed at which the right extrusion block moves forward when the pressure in the insulation airbag decreases. A front-to-back axial pressure-regulating barrel is fixed in the regulating box, and a piston that can move back and forth with the left extrusion block is provided in the pressure-regulating barrel. The rear end of the pressure-regulating barrel is connected to the insulation airbag via a pressure-regulating pipe, and a plurality of massage wheels distributed along the front-to-back direction and moving back and forth with the left extrusion plate are provided on the left and right sides of the heat dissipation pad.

[0007] The beneficial effects of the present invention are as follows: the force for binding the hot compress device to the patient is set, and even if the patient's legs move frequently, the pressure can be automatically adjusted according to the patient's movements, thereby ensuring the fixing effect of the hot compress device while maintaining the patient's force in a comfortable state that will not cause it to fall off, thereby ensuring the patient's comfort while ensuring the effect of the hot compress, and massaging the joints by changing the patient's position, further promoting blood flow, improving the effect of hot compress, and promoting patient recovery, and making the patient's hot compress no longer restricted by the external environment, and the patient can apply hot compress anytime and anywhere, and even during activities, the hot compress device will not loosen or fall off due to activities, nor will it be subjected to excessive pressure to cause poor blood circulation, thereby reducing the restrictions of hot compress on the patient himself and meeting the usage needs of patients under different conditions.

The rear end surface of the extrusion block 9 and the booster barrel 8 are filled with transmission oil 10. The contact area between the extrusion block 9 on the left and the transmission oil 10 is larger than the contact area between the extrusion block 9 on the right and the transmission oil 10. The extrusion block 9 on the right moves back and forth with the change of the pressure in the insulation airbag 3. When the pressure in the insulation airbag 3 increases, the speed at which the extrusion block 9 on the right moves backward is lower than the speed at which the extrusion block 9 on the right moves forward when the pressure in the insulation airbag 3 decreases. A front-to-back axial pressure-regulating barrel 11 is fixed in the regulating box 7, and a piston 12 that can move back and forth with the extrusion block 9 on the left is provided in the pressure-regulating barrel 11. The rear end of the pressure-regulating barrel 11 is connected to the insulation airbag 3 via a pressure-regulating pipe 13. A plurality of massage wheels 14 distributed along the front-to-back direction and moving back and forth with the extrusion plate on the left are provided on the left and right sides of the heat dissipation pad 5.

[0021] In order to make the extrusion block 9 on the right side move forward and backward as the pressure in the thermal insulation airbag 3 changes, and to increase the distance that the extrusion block 9 is driven to move by the thermal insulation airbag 3, a front-to-back axial and slender speed control barrel 15 is fixed in the regulating box 7, and a speed control block 16 is slidably connected in the speed control barrel 15. The rear end of the speed control block 16 is fixedly connected to the extrusion block 9 on the right side via a connecting column 17. A plurality of speed control holes 18 are evenly distributed along the circumferential direction and penetrated from front to back at the rear end of the speed control barrel 15. The front end of the speed control barrel 15 is connected to the thermal insulation airbag 3 via a speed control tube 19.

[0022] In order to make the speed at which the extrusion block 9 on the right side moves backward when the pressure inside the insulation airbag 3 increases slower than the speed at which the extrusion block 9 on the right side moves forward when the pressure inside the insulation airbag 3 decreases, a plurality of auxiliary holes evenly distributed along its circumferential direction and penetrating front to back are opened at the rear end of the speed control barrel 15, and the plurality of auxiliary holes are staggered with the plurality of speed control holes 18, and a front-to-rear axial block sleeve 20 with an axial cross-section of an imitation v-shaped is slidably connected in the auxiliary hole, the front and rear ends of the block sleeve 20 both extend out of the auxiliary hole and the front end of the block sleeve 20 can cover the auxiliary hole, and a plurality of through holes 21 are opened on the side wall of the block sleeve 20, penetrating inside and outside and evenly distributed along its circumferential direction.

[0023] In order to enable the piston 12 to move forward and backward with the extrusion block 9 on the left side, a turntable 22 coaxial with the pressure regulating barrel 11 and located in front of the pressure regulating barrel 11 is rotatably connected in the regulating box 7, and a screw 23 is coaxially threadedly connected on the turntable 22. The rear end of the screw 23 is coaxially fixedly connected to the piston 12, and a limiting groove 24 in the front and rear directions is opened on the screw 23. A limiting block 25 inserted into the limiting groove 24 is fixed in the regulating box 7, and a plurality of push pins 26 evenly distributed along the circumferential direction of the turntable 22 are fixed on the outside of the turntable 22. A slider 27 located on the left side of the turntable 22 and in the front and rear directions is slidably connected in the regulating box 7, and a plurality of inclined plates 28 evenly distributed along the front and rear directions and higher in the front and lower in the back are fixed to the right end of the slider 27. The push pin 26 can be inserted between two adjacent inclined plates 28, and the slider 27 can move forward and backward with the extrusion block 9 on the left side.

[0024] In order to enable the slider 27 to move forward and backward with the extrusion block 9 on the left, an inverted L-shaped push plate 30 is fixed to the front end of the extrusion block 9 on the left via a connecting rod 29, and the rear end of the push plate 30 is fixedly connected to the regulating box 7 via a constant force spring 31, and the lower end of the push plate 30 is fixedly connected to the slider 27.

[0025] In order to make the massage wheel 14 move forward and backward with the squeezing block 9 on the left side, a clearance groove is opened on the heat dissipation pad 5, and a concave pull rope 32 is respectively provided on the left and right sides of the clearance groove, and a concave auxiliary rope 33 is fixed in the middle of the pull rope 32. The massage wheel 14 is located between the auxiliary rope 33 and the pull rope 32 on its corresponding side, and a plurality of horizontal columns 34 corresponding to the massage wheels 14 on the corresponding side and axially arranged on the left and right sides are fixed between the auxiliary rope 33 and the pull rope 32. The massage wheel 14 is rotatably connected to the corresponding horizontal column 34, and moving ropes 35 are respectively fixed to the front and rear ends of the push plate 30, and the free end of the moving rope 35 is fixedly connected to the free end of the pull rope 32 on the corresponding side.

[0026] In order to make the movement of the pull rope 32 and the movable rope 35 smoother, protective covers 36 are respectively fixed on the front and rear sides of the give way groove, and the front and rear sides of the pull rope 32 are respectively located in the protective covers 36 on the corresponding sides. A protective tube 37 extending out of the air vent 4 and passing through the thermal insulation pad 2 is fixed on the heat dissipation pad 5. The protective tube 37 is fixedly connected to the control box 7, and the movable rope 35 is located in the protective tube 37.

[0027] In order to facilitate use and increase the airtightness during use, the upper end of the insulation pad 2 is fixedly connected to the middle part of the control box 7 through the connecting block 38, a Velcro is fixed to the inner surface of the free end of the strap, and three Velcro sub-tapes that correspond to the Velcro one-to-one and can be adhered to the Velcro are fixed to the upper end of the carbon nanotube heating pad 1. Sealing rings are fixed on the extrusion block 9, the piston 12 and the speed control block 16, and retaining rings 39 located in front of the extrusion block 9 are respectively fixed on the left and right sides of the force booster barrel 8.

[0028] When the present invention is in use, the initial state is that the block sleeve 20 blocks the auxiliary hole, the booster barrel 8 is filled with transmission oil 10 and no gas is present, the push column 26 is inserted between two adjacent inclined plates 28, and the threaded connection between the screw 23 and the turntable 22 is self-locking. The device can be set to different sizes to meet the hot compress needs of different joints such as the knee joint, elbow joint, and wrist joint.

[0029] When it is necessary to apply heat to the patient's joints, such as the knee joints, the patient's legs are straightened, the skin-friendly layer 6 is covered on the knee joint, and then the front strap is passed around the patient's thigh, the back strap is passed around the patient's calf, and the middle strap is passed around the knee pit. Then, the Velcro mother tape is bonded to the Velcro child tape to fix the carbon nanotube heating pad 1 at the knee joint. Due to the characteristics of the carbon nanotube heating pad 1 itself, it can be twisted and bent at will without affecting its heating effect. Therefore, the skin-friendly layer 6 can be in comprehensive and uniform contact with the patient's skin, and there will be no large-scale warping or loose fitting under the action of the insulation airbag 3.

[0030] During the binding process, the heat-insulating airbag 3 is pressurized to increase the gas pressure inside it, and the gas enters the speed control barrel 15 through the speed control tube 19, and then pushes the speed control block 16 to move backward. At this time, the stopper sleeve 20 blocks the auxiliary hole under the pressure of the gas, so that the gas behind the speed control block 16 can only flow out backward through the speed control hole 18, so that the speed control block 16 moves backward slowly, and the speed control block 16 drives the right-side extrusion block 9 to move backward through the connecting column 17, and the right-side extrusion block 9 squeezes the transmission oil 10 backward. Since the contact area between the left-side extrusion block 9 and the transmission oil 10 is larger than that on the right side, The contact area between the extrusion block 9 and the transmission oil 10 is larger than the contact area between the extrusion block 9 and the transmission oil 10 according to Pascal's law. For example, if the area of ​​the extrusion block 9 on the left is ten and the area of ​​the extrusion block 9 on the right is one, the force of the transmission oil 10 pushing the extrusion block 9 on the left to move forward is ten times the force of the connecting column 17 pushing the extrusion block 9 on the right to move backward. This achieves the effect of increasing the force, thereby ensuring that the moving rope 35 can be pulled smoothly to move, thereby ensuring the smooth massage of the massage wheel 14.

[0031] The squeezing block 9 on the left side drives the pushing plate 30 to move forward through the connecting rod 29, and the pushing plate 30 moves backward by pulling the pull rope 32 through the moving rope 35 on the rear side, and the massage wheel 14 moves backward synchronously to roll and massage the skin on both sides of the patient's knee joint to promote blood flow. At the same time, the pushing plate 30 drives the slider 27 and the inclined plate 28 to move forward, and the inclined plate 28 drives the push column 26 to rotate downward, and the push column 26 drives the turntable 22 to rotate counterclockwise. Multiple push columns 26 are gradually inserted between the inclined plates 28 in sequence and rotate under the push of the inclined plates 28. Due to the setting of the limiting groove 24 and the limiting block 25, the screw 23 cannot rotate. Therefore, the turntable 22 drives the screw 23 to move forward under the action of the thread, and the screw 23 drives the piston 12 to move forward. The space behind the piston 12 in the pressure regulating barrel 11 is increased, and the gas in the heat insulating airbag 3 is sucked into the pressure regulating barrel 11 through the pressure regulating pipe 13, thereby reducing the pressure in the heat insulating airbag 3.

[0032] Since the force applied to the push plate 30 by the constant force spring 31 is a constant force pulling backward, as the pressure in the thermal insulation airbag 3 decreases, the force of the gas pushing the speed control block 16 to move backward gradually decreases. When the force of the gas pushing the speed control block 16 to move backward reaches a balance with the constant force of the constant force spring 31, the speed control block 16 stops moving. At this time, the binding effect of the strap prevents the thermal insulation airbag 3 from expanding outward and then returning to its original state, and can only squeeze the patient's legs inward, so that the value of the squeezing force applied to the patient's legs by the gas in the thermal insulation airbag 3 is balanced with the constant force of the constant spring, thereby ensuring that the binding force is not too loose or too tight, and starting the carbon nanotube heating pad 1 to start hot compressing the knee joint.

[0033] When the patient moves his legs, that is, when the legs change from a straight state to a bent state, the knee joint begins to squeeze the thermal insulation airbag 3. The leg muscles also squeeze the thermal insulation airbag 3 while exerting force. The restraint of the strap limits the distance between the outer surface of the thermal insulation airbag 3 and the patient's skin. Therefore, the thermal insulation airbag 3 is compressed, thereby increasing the gas pressure inside it, and then the speed control block 16 moves slowly backward, the squeezing block 9 on the right moves backward, the squeezing block 9 on the left moves forward, the slider 27 moves forward, the turntable 22 rotates counterclockwise again, the piston 12 moves forward, the gas is sucked into the pressure regulating barrel 11, and the massage wheel 14 moves backward under the pull of the pull rope 32 to massage the skin on the side of the leg. When the forward squeezing force of the transmission oil 10 on the squeezing block 9 on the left is equal to the elastic force of the constant force spring 31, the speed control block 16 stops moving. At this time, the squeezing force of the airbag on the patient is equal to the initial force, and the leg will not be damaged due to the increase in the force due to the change in body position, thereby increasing the patient's comfort.

[0034] When the patient's legs are straightened again, the pressure of the knee joint on the heat-insulating airbag 3 is reduced, and the air pressure in the heat-insulating airbag 3 is reduced, so that the push plate 30 moves backward under the action of the constant force spring 31, and the push plate 30 drives the left extrusion block 9 to move backward through the connecting rod 29, and the left extrusion block 9 drives the right extrusion block 9 to move forward through the transmission oil 10, and the right extrusion block 9 drives the speed control block 16 to move forward through the connecting column 17, and the stopper sleeve 20 moves forward under the attraction of the gas, so that the through hole 21 is connected with the inside of the speed control barrel 15, and the speed of the gas entering the speed control barrel 15 is accelerated, so that the speed control block 16 moves forward quickly, and at the same time, the push plate 30 pulls the pull rope 32 forward through the front moving rope 35 The massage wheel 14 moves forward synchronously to massage the patient's legs, the push plate 30 drives the slider 27 to move backward synchronously, and the slider 27 drives the push column 26 to rotate upward through the inclined plate 28, thereby driving the turntable 22 to rotate clockwise, so that the screw 23 moves backward, and the piston 12 moves backward synchronously to make the gas in the pressure regulating barrel 11 enter the heat-insulating airbag 3, thereby increasing the pressure in the heat-insulating airbag 3, increasing the squeezing force on the patient, and preventing the patient from falling off due to the reduction of force caused by the change of body position. When the forces on the front and rear ends of the squeezing block 9 on the left side are balanced again, the push plate 30 stops moving. At this time, the force on the patient is still the force that balances the constant force spring 31, so that the force on the patient is stable.

[0035] The present invention is novel in conception, ingenious in structure, easy to operate and highly practical. The slender speed control barrel is used to amplify the slight change of air pressure, thereby increasing the moving length of the extrusion block, and then increasing the moving distance of the massage wheel, thereby improving the length and effect of the massage. The power-enhancing barrel, the extrusion block and the transmission oil are arranged, and the Pascal's law is used to amplify the weak force of the air pressure change through the power-enhancing barrel, so that the push plate can drive the massage wheel to move, and the massage is ensured to proceed smoothly. The screw, the turntable, the pressure-regulating barrel and the piston are arranged, and the movement of the piston is used to accurately and dynamically control the gas content in the heat-insulating airbag, so that the rate of change of the air pressure in the heat-insulating airbag is controlled by the speed of the screw movement, so as to ensure the stability of the force applied to the patient. The speed control hole, the auxiliary hole, the stopper sleeve and the through hole are coordinated to achieve rapid pressurization and slow decompression of the airbag, so as to prevent insufficient pressure on the legs caused by excessive decompression or excessive slow pressurization during walking. In case the fixation is not firm and it falls off, the pressure on the patient's legs is slowly reduced while ensuring the fixation effect, and the pressure is quickly increased when the leg pressure decreases to ensure the stability of the fixation. The position of the extrusion block is limited by the setting of the retaining ring to prevent the extrusion block from moving out of the force-enhancing barrel due to shaking and causing transmission oil leakage, thereby ensuring the stability of use and increasing the service life. At the same time, the constant force spring is used to limit the pressure on the patient, and the gas pressure is changed by changing the gas content in the insulation airbag to maintain a stable balance between the pressure on the patient and the elastic force of the constant force spring to prevent the pressure from being continuously too high or too low, increase the stability of the fixation, and is not affected by the external environment, so that the patient can use it in bed or while walking, reduce the impact of hot compress on the patient's daily life, facilitate patients to use, and meet the use needs of different patients.

[0036] It can be seen that the use of a rehabilitation therapy auxiliary device provided by the present invention can effectively solve the problem that the existing device is inconvenient to automatically adjust the binding force according to the patient's activities. This structure is simple to operate, easy to use, and improves the adaptability and stability of hot compress.
