Description

Technical Field

[0001] The present invention relates to the technical field of medical rehabilitation devices, and in particular to a rehabilitation device for treating edema in stroke patients. Background Art

[0002] Hemiplegia caused by stroke is a pathological condition in which a stroke causes abnormal accumulation of fluid in the brain tissue, leading to an increase in brain volume and intracranial pressure, and further causing motor dysfunction in one side of the patient's limbs. When hemiplegic patients develop secondary complications such as leg edema and pain, rehabilitation treatment usually combines an electric standing bed with massage. Specifically, the electric standing bed uses gravity to promote venous blood return in the lower limbs, and massage further accelerates blood circulation through mechanical compression. The two work synergistically to form a "gravity + mechanical" dual circulation promotion effect. In the standing position, the patient's muscle contraction and the mechanical stimulation of the massage work synergistically, which can not only more effectively improve lower limb blood circulation, but also simultaneously enhance the recovery of muscle strength and coordination, thereby improving the rehabilitation effect.

[0003] Most of the existing electric standing beds, when used for hemiplegic patients with leg edema, usually require additional air bag cuffs or independent massagers to help promote blood circulation and relieve swelling. However, this method is cumbersome to operate and it is difficult to cover the area where the legs are in contact with the bed. Even if a circular air bag cuff is used, the close contact between the back of the leg and the bed will lead to uneven pressure distribution, making the air bag unable to effectively act on the pressured area, thereby reducing the massage effect of the area, and further affecting the overall swelling of the patient's legs, and reducing the patient's rehabilitation effect and efficiency, and is not practical. Summary of the Invention

[0018] Compared with the existing technology, the advantages of the present invention are:

[0019] 1. The present invention cooperates with the bed board, the adjustment mechanism, the first massage mechanism and the second massage mechanism to not only massage the front, back and left and right sides of the patient's legs while gradually transitioning the patient from a supine position to an upright position by utilizing the inclination of the bed board, thereby effectively improving the comprehensiveness of the massage of the patient's legs, but also can avoid secondary damage to the potentially injured parts of the patient's legs by adjusting the position of the support shell before massaging the back of the patient's legs, and ensure that the main muscle groups on the back of the legs can be effectively massaged, thereby effectively improving the massage effect and efficiency of the back of the patient's legs, that is, improving the patient's rehabilitation effect and efficiency.

[0020] 2. The present invention can achieve massage of the front, back and left and right sides of the patient's legs through the mutual cooperation of the first massage mechanism and the second massage mechanism, and can also perform different massages according to the specific conditions of different positions of the legs. For the front of the leg where the muscles are thinner and close to the bones, an airbag strap is used for flexible massage. This massage method can not only penetrate into the muscle layer and effectively relieve muscle tension, but also accurately control the massage strength to avoid excessive stimulation to sensitive areas, thereby greatly reducing the massage risk while ensuring the massage efficacy. For the back and left and right sides of the legs where muscles are more distributed, in addition to using airbags for flexible massage, a massage roller can be used for rolling massage after completing the flexible massage, thereby achieving better relaxation and massage effects, that is, effectively improving the patient's rehabilitation effect.

[0021] 3. The present invention, through the setting of the second massage mechanism, can use the push of the electric telescopic rod and the rotation of the support shell to achieve a multi-mode combination massage of the back of the patient's legs. Specifically, the back of the patient's legs are subjected to heat compress by a hot compress pad, air bag massage and massage roller massage in sequence, step by step, to avoid damage caused by sudden pressure. This not only ensures the safety and comfort of the massage process, but also greatly improves the massage effect, thereby effectively accelerating the patient's recovery process and improving the recovery effect. The entire process does not require switching the entire massage device. The massage mode can be easily changed by directly rotating the support shell. The operation steps are simple, saving time and energy. The adjustment function of the electric telescopic rod can make the massage roller or air bag flexibly adapt to the different morphological characteristics of the muscles on the back of the legs, thereby achieving sufficient and effective massage and relaxation of the muscles on the back of the legs, further improving the patient's recovery effect.

[0022] 4. The present invention, through the setting of the power component in the second massage mechanism, can drive the hot compress pad, airbag or massage roller to slide in an arc shape according to needs, so that it can perform a multi-mode combination massage on the back of the patient's legs while also performing a multi-mode combination massage on the left and right sides of the patient's legs. This can improve the comprehensiveness of the massage and enhance the swelling-reducing effect, while also improving the circulatory system of the legs, reducing congestion and edema, and effectively alleviating the pain and discomfort of the patient's legs, thereby effectively improving the patient's rehabilitation effect.

[0023] 5. The present invention, through the provision of the support pad in the second massage mechanism, can not only wrap and support the back of the patient's legs when the patient first lies down, but also wrap and support other parts of the back of the patient's legs when massaging a certain part of the back of the patient's legs, thereby preventing patients with swollen joints from having an unstable center of gravity due to insufficient leg support, thereby effectively ensuring the stability and safety of the patient on the bed board, and through the provision of a pressure sensor in the support pad, it can ensure that the center of gravity of the patient's body is always in a safe area, thereby effectively ensuring the safety and effectiveness of the massage therapy, thereby ensuring the patient's rehabilitation effect and efficiency.

[0043] Reference Figures 6 to 11 , the support shell 22 and the three curved plates 25 are provided with power components for making the three curved plates 25 slide, and the power components include three curved shells 23, the three curved shells 23 are respectively installed in the three curved grooves on the support shell 22, and the positions of the three curved shells 23 respectively correspond to the positions of the driving device 24, the charging and discharging device 28 and the heating device 27, and the three curved plates 25 are respectively slidably connected to the three curved shells 23, and an arc-shaped rack 35 is installed on the side of the curved plate 25 facing the curved shell 23, and an installation groove for the arc-shaped rack 35 to pass through is opened on the side of the curved shell 23 facing the curved plate 25, and a third motor 34 is installed on the inner wall of the installation groove, and a third gear 33 is fixedly connected to the output end of the third motor 34, and the third gear 33 is meshed with the arc-shaped rack 35.

[0044] When using the present invention, the patient is first allowed to lie on the bed board 1 (i.e., on an electric standing bed), and the patient's two legs are placed on the two through slots 10 on the bed board 1 respectively. Then, the two first motors 8 are started to rotate the two screw rods 11, thereby controlling the two movable plates 14 to move to the bottom of the support shell 22 to be adjusted. Then, the lifting part is controlled to make the electromagnet 15 contact with the support shell 22 at the corresponding position, and after contact, the electromagnet 15 is started to adsorb the support shell 22 (the support shell 22 is made of magnetic material). At the same time, the lock on the mounting ring 31 is released. The locking portion is in a locked state under normal circumstances, and then the first motor 8 is started again to drive the movable plate 14 and the support shell 22 adsorbed thereon to move to a suitable position. After the position adjustment is completed, the locking portion is used to re-lock the position of the mounting ring 31. At this time, the position of the support shell 22 is also fixed. The electromagnet 15 is then turned off, and the lifting portion is controlled to move the electromagnet 15 downward and reset, thereby separating the support shell 22 from the movable plate 14. The above operation is then repeated, and the position of each support shell 22 is adjusted in turn until each support shell 22 is adjusted to a suitable position.

[0045] During the above adjustment process, it is necessary to avoid the possible injured parts of the patient's leg, and to ensure that the main muscle groups on the back of the leg can be fully wrapped by the support pad 20 on the support shell 22, so as to avoid secondary damage to the wound on the back of the patient's leg, and to ensure that the main muscle groups on the back of the leg can be effectively massaged in the future (that is, to improve the massage effect of the multi-mode massage component on the subsequent support shell 22 on the back of the patient's leg). After completing the above adjustment work, the multiple support pads 20 will rise to the through groove 10 under the action of the corresponding electric telescopic rod 32. The waist and legs of the patient are fixed on the bed board 1, and the waist and legs of the patient are fixed respectively by the waist and leg straps 5 and 6. The hand support plate 4 is then installed, and the angle of the bed board 1 is adjusted by activating the hydraulic push rod 3. During this process, as the angle of the bed board 1 changes, the patient can gradually transition from a supine position to an upright position. With the help of this change in body position, gravity can be used to promote blood to flow back to the heart more smoothly from the lower limbs, thereby effectively improving the blood circulation of the patient's lower limbs (i.e., legs).

[0046] When the bed board 1 rotates from a supine position to an upright position, the concave areas of the legs (such as the popliteal fossa) are prone to form pressure concentration points due to muscle atrophy, joint stiffness or edema. At this time, the height of the support pad 20 at the corresponding position can be dynamically adjusted by controlling the electric telescopic rod 32 to fill the gap between the concave area and the bed surface, and to evenly distribute the pressure to the muscle groups and bones on the posterior side of the entire lower limb, thereby effectively avoiding local soft tissue ischemia due to pressure, and thus playing a role in preventing adverse consequences such as pressure sores. For patients with swollen joints, the support pad 20 can also be adjusted in height in real time under the action of the electric telescopic rod 32, thereby forming a flexible buffer space between the joints and the bed board 1, thereby effectively avoiding the situation where some swollen joints are in direct contact with the bed board 1 around the through groove 10 and bear the pressure of the bed board 1, that is, avoiding the joints from directly bearing the pressure of the bed board 1, thereby effectively alleviating the patient's sense of oppression in this area and improving their comfort.

[0047] When massaging the patient's legs, the front side of the patient's legs is mainly massaged with the airbag strap 7. Before starting the massage, the appropriate number of airbag straps 7 can be selected according to the patient's leg condition and installed in the appropriate position to avoid leg injuries or sensitive areas. After the installation is completed, the slider can be moved according to the specific situation to fine-tune the position of the airbag strap 7 so that it can better fit the leg curve to improve the comfort of the airbag strap 7 massage. After completing the installation and position fine-tuning of the airbag strap 7, the airbag strap can be adjusted by controlling the inflatable part in the slider. The belt 7 is inflated and deflated to achieve a flexible massage of the front of the patient's legs. Since the muscles on the front of the legs are thin and close to the bones, if hard massage methods such as balls or rollers are used, it is easy to directly compress the bones, causing pain or even damage. The flexible massage of the airbag belt 7 can form a uniform pressure distribution during the massage process, which can not only ensure that the massage effect penetrates into the muscle layer, but also avoid local excessive stimulation, thereby better meeting the massage needs of this special area on the front of the legs, and thus can ensure the massage effect in this area while reducing the risks that may occur during the massage process.

[0048] When massaging the back of the patient's leg, the electric telescopic rod 32 is controlled to move the support pad 20 near the patient's foot down to below the through groove 10, and at the same time, the locking part on the mounting ring 31 at the corresponding position is released, and then the first motor 8 is started to move the movable plate 14 to below the support shell 22 at the corresponding position, and the first gear 16 on the movable plate 14 and the second gear 21 on the corresponding support shell 22 are in a state of mutual engagement, and then the second motor 17 is started to rotate the first gear 16, and the rotation of the first gear 16 drives the second gear 21 and the support shell 22 to rotate until the hot compress pad 29 is rotated to the position of the original support pad 20, and then the electric telescopic rod 32 is used to move the hot compress pad 29 up and fit it to the back of the leg, and then the heating device 27 is turned on to make the hot compress pad 29 perform hot compress on the back of the leg, thereby promoting blood circulation, increasing skin and muscle temperature, making the muscles more relaxed, and improving the permeability and effectiveness of subsequent massage.

[0049] After completing the above-mentioned hot compress work, the hot compress pad 29 is moved down by the electric telescopic rod 32 (the heating device 27 is in the off state at this time), and then the supporting shell 22 is rotated by the second motor 17 until the multiple air bags 30 are rotated to the original position of the hot compress pad 29. Thereafter, the multiple air bags 30 are moved up by the electric telescopic rod 32 and attached to the back of the leg, and the multiple air bags 30 are inflated and deflated by the inflation and deflation device 28, thereby performing a rhythmic flexible massage on the back of the patient's leg, thereby further promoting blood circulation, relieving muscle tension, and improving the swelling effect. Since there are more muscles distributed on the back of the leg and on the left and right sides, the flexible massage using only the air bags 30 may not be effective. The method is to achieve the expected effect. Therefore, after completing the above-mentioned flexible massage work, the multiple air bags 30 are moved downward by the electric telescopic rod 32 (at this time, the inflation and deflation device 28 is in the closed state), and then the above process is repeated until the multiple massage rollers 26 are rotated to the original positions of the multiple air bags 30. Then, the multiple massage rollers 26 are moved upward and fitted to the back of the legs by the electric telescopic rod 32, and the multiple massage rollers 26 are rotated by the driving device 24, so that the massage rollers 26 roll and massage the back of the patient's legs, deeply stimulate the acupuncture points and meridians of the legs, enhance the accuracy and effect of the massage, thereby achieving better relaxation and massage effects, that is, effectively improving the patient's rehabilitation effect.

[0050] When massaging the back of the leg, since the muscles on the back of the leg are not evenly distributed and have obvious undulations and ridges, the electric telescopic rod 32 can enable the massage roller 26 or the airbag 30 to conform to the undulations of the leg muscles during the extension process, closely fitting the muscle surface, and preventing poor massage effects due to gaps between the massage roller 26 or the airbag 30 and the muscles. This is especially true in special areas such as swollen joints and around the knee joints. By controlling the electric telescopic rod 32 to move the massage roller 26 or the airbag 30 upward, the massage roller 26 or the airbag 30 can flexibly adapt to the shape of these areas, thereby achieving sufficient and effective massage and relaxation of the muscles on the back of the leg, further improving the patient's rehabilitation effect.

[0051] In addition, during the hot compress and massage process, the third motor 34 can be started to drive the hot compress pad 29, the airbag 30 or the massage roller 26 to perform multi-dimensional hot compress or massage. Specifically, when hot compress is applied to the back of the leg, the third motor 34 at the corresponding position is started. Since the third gear 33 is engaged with the arc-shaped rack 35 on the arc-shaped plate 25 at the corresponding position, the rotation of the third gear 33 will drive the arc-shaped rack 35 to rotate together, thereby driving the hot compress pad 29 to slide in an arc, ensuring that the hot compress area accurately covers the left and right sides of the legs, achieving all-round hot compress. Similarly, when hot compress is applied to the back of the leg through the airbag 30 or the massage roller When the friction roller 26 is massaging, the third motor 34 is also used to perform arc motion to massage and reduce swelling on the left and right sides of the legs. This multi-area simultaneous massage method can fully stimulate the leg muscles and enhance the swelling reduction effect. The airbag 30 and the massage roller 26 slide in an arc on the legs with a certain force and direction. In addition to improving the comprehensiveness of the massage and thus enhancing the swelling reduction effect, it can also simulate the pushing, holding, and pressing techniques in massage through its unique movement mode, thereby helping to improve the leg's circulatory system, reduce congestion and edema, and help relieve leg pain and discomfort.

[0052] During the massage process, the order of heat compress by the hot compress pad 29, massage by the air bag 30 and massage by the massage roller 26 is gradual and in line with the principle of "from light to heavy, in stages" of traditional Chinese medicine massage, thereby avoiding possible damage caused by sudden pressure. After the support shell 22 near the patient's foot has completed the massage of the back and left and right sides of the patient's legs, the locking part is used to re-lock the position of the mounting ring 31 there, and the movement of the movable plate 14 and the first gear 16 thereon enable each support shell 22 to perform the above-mentioned multi-mode combination massage on the back and left and right sides of the patient's legs in turn. During the entire massage process, there is no need to switch the entire massage device. The massage mode can be easily changed by directly rotating the support shell 22. The operation steps are simple, saving time and energy.

[0053] Since the patient lies on the bed board 1, the legs need to share part of the body weight, so when massaging a certain part, the other parts remain supported by the support pad 20 to prevent patients with swollen joints from having an unstable center of gravity due to insufficient leg support. Once the center of gravity is unstable, it is very easy to cause the patient's entire body posture to change, which in turn seriously affects the stability of the body on the bed board 1, causing discomfort and even potential risks to the patient. At the same time, since the pressure sensor installed inside the support pad 20 can monitor the center of gravity distribution of the patient's legs in real time, when the local force changes due to the massage operation, the pressure sensor will quickly capture this change and transmit the signal in time. Subsequently, the support pad 20 will adjust its own height with the help of the electric telescopic rod 32, compensate for the pressure change in real time, and ensure that the center of gravity of the patient's body is always in a safe area, thereby effectively ensuring the safety and effectiveness of the massage therapy, and thus ensuring the patient's rehabilitation effect and efficiency.

[0054] In addition, the massage of each support shell 22 follows the order of gradually massaging from the ankle upwards, that is, applying circulatory pressure from the distal end to the proximal end of the limb, thereby simulating the "muscle pump" effect, pushing blood back to the heart, and thus promoting blood circulation in the lower limbs, reducing blood congestion, reducing the risk of thrombosis, and helping to eliminate lower limb edema, thereby further improving the rehabilitation effect. The flexible massage of the front side of the patient's legs by the multiple airbag straps 7 also follows the above-mentioned order of gradually massaging from the ankle upwards. The effect of the electric standing bed in promoting fluid reflux mainly depends on the change of body position. The gravity effect brought about is a relatively passive intervention method. On the basis of the electric standing bed, this device adds airbag straps 7 and airbags 30 to massage the lower limbs. The airbag straps 7 and airbags 30 are used to periodically inflate and deflate the lower limbs, which can simulate muscle contraction and relaxation, actively squeeze the deep veins of the limbs, thereby promoting the return of blood and lymph, and at the same time realize the combination of active muscle contraction in the standing position and passive stimulation of air pressure pulses, thereby more efficiently restoring muscle strength and coordination, and effectively improving the patient's rehabilitation effect and efficiency.
