Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a split-control physiotherapy device for use in neurology. Background Technology

[0002] Facial nerve palsy, also known as facial paralysis, is a neurological condition primarily caused by facial exposure to cold, physical injury, viral infections, and neurogenic muscle atrophy. It results from damage to the facial nerve in the facial muscles. Treatment for facial paralysis patients often yields limited results with long-term medication, requiring ongoing massage and electrical stimulation of the facial nerve. Some patients may require heat therapy to alleviate the nerve pain. However, current physiotherapy equipment cannot meet all the necessary needs of facial paralysis patients, thus delaying treatment. It has been found that electrical stimulation is more effective in stimulating the facial nerve and clearing the meridians. Current physiotherapy methods often involve applying electro-patch to the skin, which can cause skin tearing. Furthermore, static physiotherapy relying solely on electro-patch stimulation is ineffective for localized treatment and hinders facial nerve recovery. Summary of the Invention

[0003] In view of this, the present invention provides a controlled physiotherapy device for use in neurology, which presses acupoints and massages muscle groups on the patient's face, and intermittently applies electrical stimulation to the patient's face to treat facial nerve damage, thereby achieving a better therapeutic effect.

[0004] The technical solution is as follows: A split-control physiotherapy device for neurology includes a headband, a parameter adjuster fixedly connected to one side of the headband, two support blocks fixedly connected to the bottom of the headband, the two support blocks being symmetrically arranged, a clamping block fixedly connected to each of the two support blocks, a support rod slidably connected to the side of each of the two support blocks away from the clamping block, a protective shell fixedly connected to one end of each of the two support rods, an adjustment component for closely fitting the pressing contact with the patient's face in different facial states is set on the support rod and the adjustment component is connected to the support block, and an electro-contact component for massaging the patient's facial skin and electrically stimulating facial nerves is set on the protective shell.

[0005] Furthermore, the distance adjustment assembly includes a limiting plate, a limiting rod, a paddle, and a return spring. The limiting plate is fixedly connected to both support blocks. The limiting plate is provided with multiple locking blocks. The limiting rod is slidably connected to the support rod. The limiting rod and the limiting plate are located between two locking blocks on the limiting plate. A paddle is fixedly connected to the bottom end of the limiting rod. A return spring is connected between the paddle and the support rod.

[0006] Furthermore, the electrical contact assembly includes a rotating plate, a support frame, a motor, pressing contacts, and a return spring. The rotating plate is rotatably connected to one side of each of the two protective shells. The support frame is fixedly connected to the rotating plate. The motor is fixedly connected inside each of the two protective shells. The support frame is fixedly connected to the output shaft of each of the two motors. Three pressing contacts are slidably connected to the support frame. The three pressing contacts pass through the support frame and the rotating plate, and a return spring is connected between each pressing contact and the support frame.

[0007] Furthermore, it also includes a pressurizing component for increasing the pressing force. The pressurizing component is mounted on the protective shell and is connected to the support frame and the pressing contact. Each pressing contact has a locking rod fixedly connected to its top end. The locking rod is provided with multiple push discs. Three fixing frames are fixedly connected to the support frame. Push blocks are rotatably connected to each of the three fixing frames. Torsion springs are connected between the push blocks and the fixing frames. A guide ring is fixedly connected to the inner wall of the protective shell.

[0008] Furthermore, it also includes a flattening component for stretching and flattening the patient's facial skin. The flattening component is mounted on the protective shell and includes a fixing block, a spring plate, a roller, and a compression spring. Three fixing blocks are slidably connected to the protective shell, and a spring plate is fixedly connected to the side of the three fixing blocks away from the protective shell. The roller is rotatably connected to the bottom end of the spring plate, and a compression spring is connected between the fixing block and the protective shell.

[0009] Furthermore, it also includes a fixing ring and a multi-head massage plate. The multi-head massage plate consists of a circular plate and several protrusions of different heights. The protrusions are made of rubber. A fixing ring is fixedly connected to the side of the rotating plate away from the support frame, and the multi-head massage plate is fixedly connected to the fixing ring.

[0010] Furthermore, it also includes heating pads. The rotating plate has three circular grooves on the side near the support frame. Heating pads are fixedly connected in the three circular grooves of the rotating plate, and the heating pads are in contact with the pressing contact.

[0011] Furthermore, the fixing block consists of a push rod and a bolt connected to a support block at the end away from the protective shell.

[0012] The beneficial effects of this invention are as follows: First, initially, the patient wears the elastic headband on their head, and the limiting rod contacts the limiting plate. At this time, the patient presses down on the lever and moves the lever back and forth, causing the lever to move together with the limiting rod, return spring, support rod, protective shell, rotating plate, support frame, motor, pressing contacts, and return spring until the three pressing contacts contact the patient's skin. The patient releases the lever, and the return spring will drive the lever and limiting rod to return to their original positions. The limiting rod contacts the limiting plate, limiting the support rod. This allows the distance between the pressing contacts on the device and the patient's face to be adjusted according to the different degrees of facial concavity of different patients, so that the pressing contacts can conform to the height and size of different patients' faces for physiotherapy. During the physiotherapy process, the pressing contacts have a high degree of conformity with the patient's skin, resulting in better physiotherapy effects.

[0013] Second, after the headband is put on, the patient presses the parameter regulator to start the motor. The parameter regulator can adjust the rotation speed of the motor output shaft. After the motor starts, the pressing contact rotates and comes into contact with the patient's face. The parameter regulator intermittently energizes the pressing contact, which massages the patient's face. By electrically stimulating different acupoints on the face of the patient with facial paralysis, the pressing contact stimulates the facial nerves, repairs the damaged facial nerves, and provides targeted and effective treatment.

[0014] 3. After the patient adjusts the position of the pressure point against their cheek, the motor is started via the parameter adjuster. The motor's output shaft drives the rotating plate, support frame, pressure point, and return spring. The rotation of the support frame drives the fixed frame, push block, and torsion spring to rotate. The push block rotates and contacts the guide ring. This contact causes the locking rod to contact the push block, and the guide ring squeezes the push block downwards, causing the torsion spring between the push block and the fixed frame to twist. The push block then contacts one of the push rings on the locking rod, pushing the locking rod and pressure point downwards. This squeezes the return spring between the pressure point and the rotating plate, increasing the intermittent pressure on the patient's face. The motor output shaft continues to rotate the support frame, fixed frame, push block, and torsion spring. The push block disengages from the guide ring, the torsion spring resets the push block, and the return spring causes the pressure point and locking rod to rebound. This process repeats intermittently, increasing the massage intensity of the pressure point on the patient's face, clearing the facial meridians, and improving the therapeutic effect.

[0015] IV. Initially, when the patient wears the headband, the rollers will contact the patient's cheeks, and the spring plates will be compressed, allowing the rollers to fit snugly against the patient's cheeks. After the patient starts the motor, the motor drives the support frame and the fixing frame to rotate. The rotating fixing frame will contact the fixing block, and the fixing frame will push the fixing block to move, causing the fixing block to move the spring plates and rollers. The compression spring between the fixing block and the protective shell will be stretched. When the fixing frame and the fixing block are no longer in contact, the compression spring will cause the fixing block, spring plates, and rollers to return to their original positions. The rollers are composed of an axle and a rubber sleeve, which causes the rollers to intermittently push and flatten the patient's cheek skin. This process is repeated, so that the pressing contact can better electrically stimulate the patient's facial nerves, achieving a better physiotherapy effect and facilitating the recovery of facial paralysis.

Detailed Implementation

[0027] 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.

[0028] Example 1: A split-control physiotherapy device for neurology, such as Figures 1-7 As shown, the device includes a headband 1, a parameter adjuster 2 fixedly connected to one side of the headband 1, two support blocks 3 fixedly connected to the bottom end of the headband 1, the two support blocks 3 being symmetrically arranged, a clamping block 4 fixedly connected to each of the two support blocks 3, a support rod 5 slidably connected to the side of each of the two support blocks 3 away from the clamping block 4, a protective shell 6 fixedly connected to one end of each of the two support rods 5, an adjustment component for closely fitting the pressing contact with the patient's face in different facial states being disposed on the support rod 5 and the adjustment component being connected to the support block 3, and an electro-contact component for massaging the patient's facial skin and electrically stimulating the facial nerves being disposed on the protective shell 6.

[0029] The distance adjustment assembly includes a limiting plate 71, a limiting rod 72, a lever 73, and a return spring 74. The limiting plate 71 is fixedly connected to both of the support blocks 3. The limiting plate 71 is provided with multiple locking blocks. The limiting rod 72 is slidably connected to the support rod 5. The limiting rod 72 and the limiting plate 71 are located between two locking blocks on the limiting plate 71. The bottom end of the limiting rod 72 is fixedly connected to the lever 73. The return spring 74 is connected between the lever 73 and the support rod 5.

[0030] The electrical contact assembly includes a rotating plate 81, a support frame 82, a motor 83, pressing contacts 84, and a return spring 85. The rotating plate 81 is rotatably connected to one side of each of the two protective shells 6. The support frame 82 is fixedly connected to the rotating plate 81. The motor 83 is fixedly connected inside each of the two protective shells 6. The support frame 82 is fixedly connected to the output shaft of each of the two motors 83. Three pressing contacts 84 are slidably connected to the support frame 82. The three pressing contacts 84 pass through the support frame 82 and the rotating plate 81, and a return spring 85 is connected between each pressing contact 84 and the support frame 82.

[0031] Initially, the patient places the elastic headband 1 on their head. The headband 1 clamps the patient's head securely through its elasticity. Two clamping blocks 4 on the headband 1 fit snugly against the back of the patient's ears. These two clamping blocks 4 are made of elastic material, ensuring a tight fit between the headband 1 and the back of the patient's ears, improving the patient's comfort when wearing the headband 1. After the patient has put on the headband 1, initially, the limiting rod 72 is in contact with the limiting plate 71. The patient then moves the lever 73 downwards, disengaging the limiting rod 72 from the limiting plate 71, causing the lever 73 to engage with the limiting plate 71. The positioning lever 72 moves downwards together, stretching the return spring 74. At this time, the patient presses down on the lever 73 and moves it back and forth, causing the lever 73 to move together with the limiting lever 72, the return spring 74, the support rod 5, the protective shell 6, the rotating plate 81, the support frame 82, the motor 83, the pressing contact 84, and the return spring 85 until the three pressing contacts contact the patient's skin. The patient releases the lever 73, and the return spring 74 will cause the lever 73 and the limiting lever 72 to return to their original positions. The limiting lever 72 will then re-engage with the limiting plate 71, restoring the support... The lever 5 provides a limit, allowing adjustment of the distance between the pressing contact 84 and the patient's face according to the varying degrees of facial concavity. This ensures a better fit to different patients' facial heights and sizes, enhancing the therapeutic effect during treatment. After wearing the headband 1, the pressing contact 84 is pressed firmly against the patient's cheek. The patient presses the parameter adjuster 2 to start the motor 83. Adjusting the parameter adjuster 2 regulates the rotation speed of the motor 83's output shaft. After the motor 83 starts, the output... The shaft drives the support frame 82, rotating plate 81, pressing contact 84, and return spring 85 to rotate. At this time, the pressing contact 84 rotates and comes into contact with the patient's face, causing the spring between the pressing contact 84 and the support frame 82 to be stretched to different degrees, so that the pressing contact 84 can better fit the patient's skin for pressing. The parameter regulator 2 intermittently energizes the pressing contact 84, which massages the patient's face and electrically stimulates different acupoints on the face of the patient with facial paralysis, stimulating the facial nerves and thus improving facial nerve function.

[0032] Example 2: Based on Example 1, such as Figures 7-9As shown, it also includes a pressure boosting component for increasing the pressing force. The pressure boosting component is mounted on the protective shell 6 and is connected to the support frame 82 and the pressing contact 84. Each pressing contact 84 has a locking rod 91 fixedly connected to its top end. The locking rod 91 is provided with multiple push discs. Three fixing frames 92 are fixedly connected to the support frame 82. Push blocks 93 are rotatably connected to each of the three fixing frames 92. Torsion springs 94 are connected between the push blocks 93 and the fixing frames 92. A guide ring 95 is fixedly connected to the inner wall of the protective shell 6. The push blocks 93 are in contact with the guide ring 95 and the locking rod 91.

[0033] After the patient adjusts the position of the pressing contact 84 against their cheek, the motor 83 is started via the parameter adjuster 2. The output shaft of the motor 83 drives the rotating plate 81, the support frame 82, the pressing contact 84, and the return spring 85. The rotation of the support frame 82 drives the fixed frame 92, the push block 93, and the torsion spring 94 to rotate. The rotation of the push block 93 causes it to contact the guide ring 95. The contact between the push block 93 and the guide ring 95 causes the locking rod 91 to contact the push block 93. The guide ring 95 squeezes the push block 93 and causes it to swing downward, thus twisting the torsion spring 94 between the push block 93 and the fixed frame 92. The push block 93 then contacts one of the push rings on the locking rod 91. When the push block 93 is pressed, it will push the locking rod 91 and the pressing contact 84 downward, compressing the return spring 85 between the pressing contact 84 and the rotating plate 81, thus increasing the intermittent pressing pressure on the patient's face. The output shaft of the motor 83 drives the support frame 82, the fixing frame 92, the push block 93 and the torsion spring 94 to continue rotating. The push block 93 disengages from the guide ring 95, the torsion spring 94 drives the push block 93 to reset, and the return spring 85 drives the pressing contact 84 and the locking rod 91 to rebound. This process repeats, intermittently increasing the massage intensity of the pressing contact 84 on the patient's face, achieving a better physiotherapy effect and clearing the meridians on the patient's face.

[0034] Example 3: Based on Example 2, such as Figure 5 , Figure 7 and Figure 10 As shown, it also includes a flattening component for stretching and flattening the patient's facial skin. The flattening component is mounted on the protective shell 6. The flattening component includes a fixing block 101, a spring plate 102, a roller 103, and a compression spring 104. Three fixing blocks 101 are slidably connected to the protective shell 6. The spring plate 102 is fixedly connected to the side of the three fixing blocks 101 away from the protective shell 6. The roller 103 is rotatably connected to the bottom end of the spring plate 102. The compression spring 104 is connected between the fixing block 101 and the protective shell 6.

[0035] Initially, when the patient wears the headband 1, the roller 103 contacts the patient's cheek, and the spring plate 102 is compressed, allowing the roller 103 to fit tightly against the patient's cheek. After the patient starts the motor 83, the motor 83 drives the support frame 82 and the fixing frame 92 to rotate. The rotating fixing frame 92 contacts the fixing block 101, and the fixing frame 92 pushes the fixing block 101 to move, causing the fixing block 101 to drive the spring plate 102 and the roller 103 to move. The compression spring 104 between the fixing block 101 and the protective shell 6 is stretched. When the fixing frame 92 disengages from the fixing block 101, the compression spring 104 will drive the fixing block 101, the spring plate 102, and the roller 103 to return to their original positions. The roller 103 consists of a shaft and a rubber sleeve, which causes the roller 103 to intermittently push and flatten the patient's cheek skin, repeating this process to achieve a better massage effect, better electrical stimulation of the patient's facial nerves, and promote the recovery of facial paralysis.

[0036] Example 4: Based on Example 3, such as Figure 4 As shown, it also includes a fixing ring 111 and a multi-head massage plate 112. The multi-head massage plate 112 is composed of a circular plate and several protrusions of different heights. The protrusions are made of rubber. The fixing ring 111 is fixedly connected to the side of the rotating plate 81 away from the support frame 82. The multi-head massage plate 112 is fixedly connected to the fixing ring 111.

[0037] Initially, after the patient puts on the headband 1, the contact head 84 is pressed against the patient's cheek to provide electrical stimulation and restore the facial nerves. The multi-head massage plate 112 also contacts the middle of the patient's cheek. When the patient starts the motor 83, the rotating plate 81 rotates, which drives the fixed ring 111 and the multi-head massage plate 112 to rotate. The multi-head massage plate 112 massages the middle of the patient's cheek, controlling the facial muscles and nerves, promoting blood circulation and soothing the nerves.

[0038] Example 5: Based on Example 4, such as Figure 7 As shown, it also includes heating pads 12. The rotating plate 81 has three circular grooves on the side near the support frame 82. Heating pads 12 are fixedly connected in the three circular grooves of the rotating plate 81. The heating pads 12 are in contact with the pressing contact 84.

[0039] When massaging the patient's face, a heating pad is inserted into the groove of the rotating plate. The heating pad comes into contact with the pressing contact head, and the heating pad heats up and transfers heat to the pressing contact head, warming the patient's face, relieving facial stiffness, and achieving a better therapeutic effect, thus promoting the recovery of facial nerves in patients with facial paralysis.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
