Description

Technical Field

[0001] The present invention relates to the technical field of physical therapy devices, and in particular to a passive rehabilitation training and massage device integrating the PNF principle. Background Art

[0002] Proprioceptive neuromuscular facilitation (PNF) is based on neurodevelopmental science. It activates proprioceptors and neuronal circuits through vision, hearing, touch, passive stretching, resistance, and squeezing mechanisms, combined with bionic massage techniques simulated by electrical stimulation, to achieve neuromuscular re-"education". This technology is widely used in the treatment of patients with central nervous system injuries and musculoskeletal diseases.

[0003] The clinical treatment is divided into three stages: joint compression to stabilize posture, spiral diagonal guidance of limbs to promote coordination, rhythmic resistance training to optimize neuromuscular recruitment, and electrical stimulation output pulses to simulate massage techniques such as kneading and pressing, dynamically adjusting muscle tension and loosening deep fascia. Studies have shown that this technology can increase the coordination index of antagonistic muscle groups by 35.7%. Based on this, we propose a passive rehabilitation training and massage device that integrates passive motion guidance and electrical stimulation massage functions and the PNF principle.

[0004] The prior art also has the following defects during use:

[0005] Existing PNF-based physiotherapy rehabilitation training devices all assist the operator in stretching and resisting the patient's body, thereby achieving rehabilitation training for the patient's body. The device cannot independently perform rehabilitation training for the patient. The degree of automation of the device is not ideal, and it is somewhat dependent on the operator's skills and techniques.

The guide rail controller 302 can be connected to the console 104 through a cable to power the guide rail 3 and control the guide rail 3 to drive the physical therapy component 2. The guide rail 3 drives the physical therapy component 2 to move in the form of electromagnetic drive. The slide groove can provide space for the physical therapy component 2 to move, and the plug connector 301 can be card-connected with the card seat 111, so as to facilitate quick disassembly and assembly of the guide rail 3.

[0038] Two sets of physical therapy components 2 are installed at the bottom of the guide track 3. The physical therapy components 2 as a whole can cooperate with the guide track 3 to stretch, resist and relax the user's limbs. By driving the user's limbs to move, the user's limbs rotate with the physical therapy components 2 within the range of 0 to 90 degrees, and at the same time, a force of 0 to 500 Newtons is applied to the user's limbs, so that the device can replace manual labor to perform automated PNF rehabilitation training on the user's limbs, realize passive exercise and massage for patients, and achieve the purpose of saving manpower.

[0039] Furthermore, the physiotherapy component 2 includes a first mounting ring 21, which is a C-shaped ring. One end of the first mounting ring 21 is equipped with a mounting shaft 212, and the other side of the mounting shaft 212 is rotatably equipped with another first mounting ring 21. The top and bottom sides of the first mounting ring 21 are both provided with magnetic seats 211. The two sides of the first mounting ring 21 in the vertical direction are magnetically mounted with second mounting rings 22 through the magnetic seats 211. The tops of the first mounting ring 21 and the second mounting ring 22 are both A controller 23 is fixedly installed, and a plurality of airbag shells 24 are fixedly installed on the inner sides of the first mounting ring 21 and the second mounting ring 22, and an electrode sheet 243 is fixedly installed at the central position of the airbag shell 24, and an arc-shaped slide rail 244 is fixedly installed between the electrode sheets 243. A plurality of circular slots are opened on the outer side of the arc-shaped slide rail 244, and a convex roller shaft 245 is clamped and installed between the circular slots. The side of the convex roller shaft 245 is provided with a plurality of The airbag shell 24 is provided with a plurality of anti-slip contacts 242 on the surface of the airbag shell 24. An air supply pipe 241 is fixedly installed on one side of the airbag shell 24. An air pump 246 is fixedly installed on the end of the air supply pipe 241 away from the airbag shell 24. The air pump 246 adopts the V200-B3C5V type. A connecting pipe 248 is installed horizontally inside the airbag shell 24. An exhaust pipe 249 is fixedly installed in the connecting pipe 248 in the vertical direction. The first mounting ring A clamping joint 214 is provided on the side of the airbag housing 21 away from the mounting shaft 212, and a clamping sleeve 213 is sleeved on the outer side of the clamping joint 214. An exhaust valve 247 is fixedly mounted on the bottom of the airbag housing 24, and the diameter of the exhaust valve 247 is half that of the connecting tube 248. A connecting hole 2410 is opened on the side of the airbag housing 24, and the connecting holes 2410 on the sides of two adjacent airbag housings 24 are aligned in position. The arc-shaped slide rail 244 and the raised roller shaft 245 are electrically connected to the controller 23 via wires.

[0040] The first mounting ring 21 can form an annular structure through the mounting shaft 212, so that multiple groups of annular structures can be sleeved on the outside of the user's torso to facilitate passive rehabilitation and physiotherapy training for the user. The magnetic seat 211 can attract multiple first mounting rings 21 and second mounting rings 22 together through magnetic force, thereby combining multiple annular structures into a cylindrical structure, so as to expand the effective area of ​​the device, so that the device can perform powerful rehabilitation and physiotherapy massage training on the user's torso. The second mounting ring 22 can be combined with the first mounting ring 21, so that multiple first mounting rings 21 and second mounting rings 22 are combined into a cylindrical structure, and then the combined cylindrical structure is sleeved on the outside of the user's torso to perform rehabilitation and physiotherapy massage training on the user. The controller 23 It can connect other electronic components through cables, and then control other electronic components inside the device, so that each electronic component cooperates with each other to complete the work. One side of the airbag shell 24 is a hard shell, and one side of the hard shell is fixedly connected to the first mounting ring 21 and the second mounting ring 22. The other side is a curved elastic structure, which can expand and deform after internal inflation, thereby moving the electrode sheet 243 and the surrounding components, so that the device can adapt to different users. At the same time, by adjusting the internal air pressure value of the airbag shell 24, the pressure and contact area of ​​the electrode sheet 243 and the convex roller 245 when they contact the user's body surface are changed, so as to achieve the purpose of adjusting the physical therapy effect. The electrode sheet 243 can contact the user's body surface after the airbag shell 24 is inflated. Therefore, after the electrode sheet 243 is energized, micro-current stimulation can be performed on the user's muscles, thereby causing the user to produce a physiological reaction, and then the user can undergo rehabilitation massage therapy training. The arc-shaped slide rail 244 can limit the two ends of the convex roller 245, so that the convex roller 245 can move back and forth along the arc-shaped slide rail 244, and then the convex roller 245 can be used to massage the user. At the same time, after the convex roller 245 is energized, the convex roller 245 contacts the user's body surface and performs micro-current stimulation on the user. In conjunction with the electrode sheet 243, the device can enhance the rehabilitation massage therapy training effect on the user. The anti-slip contact 242 can enhance the friction between the airbag shell 24 and the user's skin, thereby enhancing the stability of the device during installation. To prevent the device from sliding during operation and affecting the accuracy of physical therapy training, the air supply pipe 241 can connect the airbag shell 24 with the air pump 246, so that the air pump 246 can inflate the interior of the airbag shell 24 after power is turned on, so as to increase the internal air pressure value of the airbag shell 24, so that the airbag shell 24 expands and deforms, and then fix the device to the outside of the user's limb. The air pump 246 adopts the VTN600 model. After power is turned on, the air pump 246 can inflate the interior of the airbag shell 24, and then adjust the internal air pressure value of the airbag shell 24, so that the airbag shell 24 expands and deforms after the internal air pressure value increases. On the one hand, the inner diameter of the device can be reduced by the expansion of the airbag shell 24 to fix the device to the outside of the user's limb. On the other hand, the expansion and contraction of the airbag shell 24 can be used.The convex roller 245 is pushed to move so that the convex roller 245 can massage the user's limbs. The microcurrent applied to the user's limbs by the convex roller 245 can enhance the rehabilitation and physical therapy training effect of the device on the user. The connecting pipe 248 can connect several airbag shells 24 in series, so that the air pump 246 can supply air to the multiple airbag shells 24. The exhaust pipe 249 can allow the air inside the connecting pipe 248 to enter the interior of the airbag shell 24, so as to blow the air into the airbag shell 24 respectively and control the expansion amplitude of the airbag shell 24 to achieve the purpose of controlling the convex roller 245. To achieve the desired range of movement, the clamping joint 214 and the clamping sleeve 213 can position and fix two adjacent first mounting rings 21 or second mounting rings 22, thereby cooperating with the mounting shaft 212 to form a ring-shaped structure. The exhaust valve 247 can exhaust air from the interior of the airbag housing 24, thereby cooperating with the air supply pipe 241 to control the expansion range of the airbag housing 24. The connecting hole 2410 can connect the connecting pipes 248 in two adjacent airbag housings 24 in series, allowing the air pump 246 to simultaneously pump air into multiple airbag housings 24.

[0041] Furthermore, a snap-in hole is provided at the top of the snap-in seat 111, and the diameter of the snap-in seat 111 is larger than the diameter of the propulsion airbag 109. The snap-in seat 111 is connected to the plug-in rod by vertical plugging, which can facilitate the rapid disassembly and assembly of the slider 105 and the guide rail 3, so as to switch the guide rail 3 between different states, and then perform passive rehabilitation training and auxiliary massage exercises on the patient's upper limbs and lower limbs respectively.

[0042] Furthermore, an airbag controller 108 is fixedly installed on the side of the slider 105, and the airbag controller 108 is connected to the propulsion airbag 109. The airbag controller 108 can control the propulsion airbag 109, thereby causing the propulsion airbag 109 to push the clamping seat 111 and the components on its top to move vertically, so as to adjust the height of the physical therapy component 2 during the physical therapy process, thereby controlling the physical therapy massage effect of the device on the patient's upper or lower limbs, and achieving different degrees of rehabilitation massage training for the patient by performing different degrees of stretching and resistance on the patient's upper or lower limbs, thereby improving the practicality of the device and its applicability among different patients.

[0043] Furthermore, a clamping rod is provided at the bottom of the plug connector 301, which fits into the clamping hole at the top of the clamping seat 111, and the clamping rod is a cylindrical structure. The clamping rod can be inserted into the clamping seat 111, thereby connecting the guide rail 3 and the slider 105, and when the slider 105 slides on the outside of the screw rod 102, it can rotate between the guide rail 3 and the slider 105, thereby avoiding the slider 105 from causing excessive twisting of the guide rail 3, thereby avoiding damage to the guide rail 3.

[0044] Furthermore, one end of the screw rod 102 passes through the mounting platform 103 and extends to the outside of the mounting platform 103, and the other end of the screw rod 102 is connected to the mounting platform 103 through a bearing. A drive motor 101 is fixedly installed on one end of the screw rod 102, and the drive motor 101 is fixedly connected to the mounting platform 103. The drive motor 101 adopts the YE4-500KW model. After the drive motor 101 is energized, it can drive the screw rod 102 to rotate, and then the screw rod 102 drives the slider 105 to move horizontally. The working state of the guide rail 3 can be adjusted by adjusting the position of the slider 105, so that the device can switch between state one, state two, state three and state four respectively, thereby performing passive massage rehabilitation training on the left hand, right hand, left leg and right leg respectively.

[0045] Furthermore, two sliding bases are slidably installed on the inner side of the guide rail 3, and the sliding bases are fixedly connected to the sides of the physical therapy component 2. The sliding bases can slide on the inner side of the guide rail 3 and drive the physical therapy component 2 to move, thereby enabling the physical therapy component 2 to drive the patient's upper limbs or lower limbs to move, thereby achieving rehabilitation training for the patient's upper limbs or lower limbs.

[0046] Furthermore, the second mounting ring 22 has the same structure as the first mounting ring 21, and the installation direction of the second mounting ring 22 is set at a ninety-degree angle with the installation direction of the first mounting ring 21. The second mounting ring 22 and the first mounting ring 21 can form a cylindrical multi-point microcurrent therapy device, thereby facilitating effective massage rehabilitation therapy training for users.

[0047] Working principle: After the device is assembled and checked and confirmed to be correct, the patient lies flat on the bed 1, and the lead screw 102 is driven by the driving motor 101 to rotate, and the slider 105 is moved to the specified position. The guide rail 3 is installed on the top of the slider 105, and the physiotherapy component 2 combined into a cylindrical structure is set on the outside of the user's upper or lower limbs. The air pump 246 supplies air to several air bag shells 24, so that the air bag shells 24 are inflated and expanded, and the inner diameter of the device is reduced, so that the device is worn on the outside of the user's limbs. At the same time, the electrode sheet 243 and the convex roller 245 are in contact with the user's skin, and the controller 23 supplies power to the electrode sheet 243 and the arc-shaped slide rail 244, so that the electrode sheet 243 and the convex roller 245 are applied to the user's muscles The microcurrent is released intermittently at certain parts of the body, and the muscles of the user's limbs are stimulated by the microcurrent to massage the user, thereby performing rehabilitation physiotherapy training. During the physiotherapy, the air inside the airbag shell 24 is intermittently released by controlling the exhaust valve 247, so that several airbag shells 24 are expanded and contracted reciprocatingly, thereby pushing the convex roller 245 to move back and forth on the outside of the user's limbs, thereby massaging the muscles at that position during the microcurrent physiotherapy. At the same time, the speaker 107 issues a voice prompt, so that the patient cooperates with the voice to resist the resistance applied to the upper or lower limbs by the device. During the entire exercise process, the patient needs to keep his full attention on the limb being exercised according to the voice prompt, so as to enhance the nerve center's ability to integrate information from the visual system, auditory system and motor system. The propulsion airbag 109 simultaneously pushes the top component to move vertically, adjusts the height of the guide rail 3 and the physical therapy component 2, and enables the physical therapy component 2 to perform passive PNF rehabilitation massage training on the patient's upper or lower limbs. After completing a training session, the guide rail 3 is disassembled, the position of the slider 105 is adjusted again, and the guide rail 3 is installed on the top of the adjusted slider 105. The device is switched between state one, state two, state three and state four, and PNF rehabilitation training is performed on the left hand, right hand, left leg and right leg respectively.

[0048] Example 2, as Figure 12As shown, the difference from the above embodiment is that, in this embodiment, two groups of sliders 105 are slidably installed on the outer side of the screw rod 102, and a group of guide rails 3 are installed above the two groups of sliders 105, and only one group of physical therapy components 2 is installed at the bottom of each guide rail 3. The distance between the two sliders 105 on the same side is consistent with the length of the user's forearm or calf. When the physical therapy components 2 at the bottom of the two guide rails 3 are in use, in the initial position, the physical therapy components 2 are in contact with the user's wrist, elbow joint or ankle, knee joint respectively, so that the user's limbs are in a horizontal state, and the wrist, elbow joint or The ankles and knee joints are in contact with the bed 1. When the device starts working, the physical therapy component 2 applies a pulling force to the user, so that the wrists, elbows or ankles, knees are respectively guided by the two guide rails 3 to perform arc movements along two trajectories, thereby completing the stretching, resistance and relaxation of the arms or legs, thereby enhancing the stretching effect of the device on the limbs. In this process, the stimulation of the proprioceptors is enhanced, further promoting the patient's limb movement coordination ability and joint stability, and enhancing the adaptability of the device in the rehabilitation training process to adapt to a variety of different forms of training categories, thereby increasing the practicality of the device.
