Description

Technical Field

[0001] The present invention relates to the technical field of medical device apparatuses, and particularly to a portable facial paralysis physiotherapy apparatus and an operation method thereof. Background Technique

[0002] Facial paralysis (also known as facial nerve palsy) is a common neurological disease, mainly manifested as the motor dysfunction of facial muscles. Patients usually present symptoms such as paralysis of the facial expression muscles on one side, drooling, and difficulty in closing eyes. The causes of facial paralysis are diverse, including viral infections, trauma, tumors, vascular diseases, etc. Although most cases of facial paralysis can recover on their own within a certain period of time, in some patients, due to incomplete recovery, facial deformity and dysfunction may persist for a long time, which has a greater impact on the quality of life of the patients.

[0003] After retrieval, it is found that the prior art publication number is CN220554541U, which discloses a facial paralysis physiotherapy apparatus, including a fixing plate, and a physiotherapy mechanism is arranged at the bottom of the fixing plate; the physiotherapy mechanism includes a motor, a motor shaft, a fixing disk, a massage ball, a fixing rod, an annular shell, an arc-shaped hole, a waterproof and breathable film, and an annular electric heating tube; a motor is bolted to the top of the fixing plate, the motor shaft is connected to the bottom of the motor, and the bottom of the motor shaft passes through the fixing plate and is fixedly connected to the fixing disk. Through the annular electric heating tube and the waterproof and breathable film in the annular shell, during the process of the massage ball massaging the face, the annular electric heating tube can be used for heating to generate hot steam inside the annular shell, and the hot steam passes through the waterproof and breathable film to fumigate the face, so as to simultaneously perform facial fumigation and massage. Moreover, an infrared physiotherapy lamp is arranged at the bottom of the annular shell, which can promote blood circulation of the face through the infrared physiotherapy lamp while performing massage and fumigation, and perform multiple physiotherapies simultaneously.

[0004] Therefore, based on the above retrieval and combined with the existing technology, the above solution includes multiple functional modules, and users may need to perform cumbersome settings and operations according to different treatment requirements. When the annular electric heating tube generates hot steam during use, although it can provide a fumigation effect, if there is no effective temperature control system for too high a temperature or steam, it may cause discomfort or scalding risks to the face, and the practicability is not strong. For this reason, we propose a portable facial paralysis physiotherapy apparatus and an operation method thereof. Summary of the Invention

[0005] The purpose of the present invention is to provide a portable facial paralysis physiotherapy apparatus and an operation method thereof, so as to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present invention provides the following technical solution: a portable facial paralysis physiotherapy instrument, including a face mask, a strap is detachably installed at the left end of the face mask for fixing the face mask on the face, a plurality of fixed cylinders are fixedly installed at the inner end of the face mask, an outer spherical shell capable of fitting with the face is arranged at the left end of each fixed cylinder, a vibration device is arranged inside the outer spherical shell for physiotherapy of the facial paralysis part, an electromagnetic shell is fixedly installed at the inner end of the fixed cylinder through bolts, an electromagnetic coil is wound at the inner end of the electromagnetic shell, and a magnetic field is generated after the electromagnetic coil is energized, so as to realize the treatment of the facial paralysis part of the patient. A water tank is fixedly installed at the inner end of the fixed cylinder, the water tank is connected with the electromagnetic shell through a solenoid valve, an inner spherical shell is fixedly sleeved at the inner end of the electromagnetic shell, and iron sand is filled at the inner end of the inner spherical shell.

A central rod penetrates through the inner end of the outer movable tube, and a driving sleeve is sleeved on the outer surface of the central rod.

[0008] As a further scheme of the present invention, the driving sleeve is located on the right side of the outer movable tube. A corrugated tooth is fixedly connected to one end of the outer movable tube close to the driving sleeve, and a roller is rotatably installed at one end of the driving sleeve close to the outer movable tube. The roller contacts with the outer surface of the corrugated tooth. Through the contact between the roller and the corrugated tooth, the driving sleeve can effectively transmit the rotational torque, so that the corrugated tooth generates a stable movement during rotation.

[0009] As a further scheme of the present invention, a sliding sleeve is sleeved on the outer surface of the central rod. The sliding sleeve is located on the right side of the driving sleeve. A plurality of passive grooves are formed at the right end of the driving sleeve. The passive grooves are arranged in a ring shape. A plurality of clamping blocks are fixedly installed at one end of the sliding sleeve close to the driving sleeve, and the clamping blocks correspond to the sliding sleeve.

The synchronous shaft is rotatably connected to the passive gear ring, and the reversing push rod can drive the passive gear ring to move left and right through the synchronous shaft.

[0011] As a further solution of the present invention, a fixing ring is fixedly installed at the inner end of the internal fixing tube. Both the upper and lower ends of the fixing ring are fixedly connected with conduction tubes. Two through holes are formed on the outer surface of the extrusion block, and the through holes correspond to the two conduction tubes. The installation of the fixing ring can effectively and firmly connect the internal fixing tube and the conduction tubes, ensuring that each component will not loosen or shift during use.

[0012] As a further solution of the present invention, a conduction through hole is formed on the outer surface of the conduction tube.

[0016] 1. When the present invention is used, by attaching iron sand to the outer surface of the magnetic coil to enhance the magnetic force of facial magnetic therapy, the magnetic field intensity in the treatment area is increased. Even if the battery capacity and current cannot provide too high energy, the magnetic field can be locally concentrated, which helps to improve facial blood circulation and nerve stimulation. Therefore, a stronger treatment effect can be achieved under the same current condition. In this way, the consumption of the battery can be optimized, the use time of the device can be extended, and it helps to make up for the problem of the small battery in the portable physiotherapy device;

[0017] 2. Through the combined use of the two treatment methods of the present invention, they can work synergistically to more efficiently promote the recovery of facial paralysis. Electromagnetic therapy promotes nerve repair and blood circulation, while vibration therapy provides muscle relaxation and nerve stimulation, thereby helping patients to restore normal facial functions in a shorter time;

[0018] 3. The design of the present invention is compact and lightweight, with good portability, enabling users to carry it easily. It can be conveniently used whether at home, in the office, or in outdoor environments.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Example 1: Please refer to Figure 1 - Figure 4 , a portable facial paralysis physiotherapy device and its operation method, including a mask 1. A strap 3 is detachably installed at the left end of the mask 1 for fixing the mask 1 on the face. Specifically, the strap 3 has an adjustable length or elasticity, and the tightness is adjusted through an adjustment buckle (such as a magic tape, a sliding buckle, a buckle ring, etc.) to adapt to different head sizes and ensure that patients of various body types can wear it comfortably. A plurality of fixing cylinders 102 are fixedly installed at the inner end of the mask 1 through bolts. An outer spherical shell 101 capable of fitting with the face is provided at the left end of each fixing cylinder 102. A vibration device is provided inside the outer spherical shell 101 for physiotherapy of the facial paralysis part. A control terminal 2 is fixedly connected to the front end of the mask 1 through bolts. The control terminal 2 can adjust the vibration frequency of the vibration device and supports customizing different vibration frequencies according to requirements. An electromagnetic shell 104 is fixedly installed at the inner end of the fixing cylinder 102 through bolts. An electromagnetic coil 109 is wound at the inner end of the electromagnetic shell 104. After the electromagnetic coil 109 is energized, a magnetic field is generated, thereby realizing the treatment of the facial paralysis part of the patient;

[0035] Specifically, the input end and the output end of the electromagnetic coil 109 are both connected to the circuit module inside the control terminal 2. A high-frequency oscillator for controlling the working frequency of the electromagnetic coil 109, a vibration control circuit for controlling the vibration device, and other circuit modules for realizing various adjustment modes are integrated on the circuit board inside the control terminal 2. At the same time, a rechargeable battery is also provided inside, which is a specific existing mature technology and will not be elaborated here;

[0036] The inner end of the fixed cylinder 102 is fixedly installed with a water tank 105 through bolts. The water tank 105 is connected to the electromagnetic shell 104 through a solenoid valve 110, and the solenoid valve 110 is connected to the control terminal 2 through a wire. Both the inside of the water tank 105 and the electromagnetic shell 104 are filled with pure water (deionized water). This liquid does not contain free ions and thus does not have electrical conductivity. The electromagnetic coil 109 is made of copper, has good electrical conductivity, and its outer surface is immersed in deionized water. There is a certain distance between the turns of the electromagnetic coil 109 to avoid contact on the outer surface, thereby affecting the electromagnetic intensity. The inner end of the electromagnetic shell 104 is fixedly sleeved with an inner spherical shell 103 by means of heat melting. The inner end of the inner spherical shell 103 is filled with iron sand. Specifically, the inner spherical shell 103 is made of soft rubber. Then when the gap between the iron sands becomes smaller, the whole inner spherical shell 103 becomes harder, and then vibration therapy is performed on the patient's face. The right end of the water tank 105 is fixedly connected with a water pump 106. The impeller of the water pump 106 is located inside the water tank 105. The specific working principle of the water pump 106 is a mature existing technology and will not be elaborated here. The water tank 105 is connected to the inner spherical shell 103 through a water delivery pipe 107. Filter meshes are provided at both the left and right ends of the water delivery pipe 107 and inside the solenoid valve 110 to prevent the iron sand inside the inner spherical shell 103 from entering the inside of the water tank 105.

[0037] Example 2: Please refer to Figure 4 、 Figure 5 、 Figure 6 , a portable facial paralysis physiotherapy device and its operation method. Based on Example 1, the vibration device includes an inner fixed tube 201. The inner fixed tube 201 is fixedly welded to the inner end of the fixed cylinder 102. An outer movable tube 212 passes through the inner end of the inner fixed tube 201, and the outer movable tube 212 is connected to the inner fixed tube 201 through a return spring 211. A rectangular groove is formed on the outer surface of the outer movable tube 212. The rectangular block fixedly installed at the inner end of the inner fixed tube 201 penetrates into this rectangular groove, so that the outer movable tube 212 does not rotate when moving left and right inside the inner fixed tube 201. The left end of the outer movable tube 212 is fixedly welded with a pressing block 210, and the pressing block 210 penetrates into the inside of the inner spherical shell 103. Specifically, the outer surface of the inner spherical shell 103 is in close fit with the inner end of the electromagnetic shell 104. Then when the pressing block 210 moves to the left, the inner spherical shell 103 cannot expand around, but can only expand to the left, thereby realizing the extrusion of the iron sand inside the inner spherical shell 103 and making the gap between the iron sands smaller;

[0038] The inner end of the outer movable tube 212 is penetrated by a center rod 209, and the outer surface of the center rod 209 is sleeved with a driving sleeve 401, and the driving sleeve 401 is located on the right side of the outer movable tube 212. The end of the outer movable tube 212 close to the driving sleeve 401 is fixedly welded with a corrugated tooth 213, and the end of the driving sleeve 401 close to the outer movable tube 212 is rotatably mounted with a roller 407, and the roller 407 is in contact with the outer surface of the corrugated tooth 213. When the driving sleeve 401 rotates, the roller 407 is rotated on the corrugated tooth 213. 3 rolls and contacts the crest of the corrugated tooth 213, pushing the outer movable tube 212 to the left, compressing the return spring 211, and then returning to the trough of the corrugated tooth 213 during the continuous rolling process. At this time, the compressed return spring 211 pushes the outer movable tube 212 to the right under the action of elastic force, and reciprocates in sequence, at which time the iron sand inside the inner spherical shell 103 can be driven to vibrate through the extrusion block 210, thereby realizing vibration therapy for the patient's face.

[0039] like Figure 6 As shown, the outer surface of the center rod 209 is sleeved with a sliding sleeve 405, and the sliding sleeve 405 is located on the right side of the driving sleeve 401. A plurality of passive grooves 406 are provided at the right end of the driving sleeve 401, and the passive grooves 406 are arranged in a ring shape. A plurality of clamping blocks 403 are fixedly installed at one end of the sliding sleeve 405 close to the driving sleeve 401, and the clamping blocks 403 correspond to the sliding sleeve 405. A passive gear ring 206 is fixedly welded at one end of the sliding sleeve 405 away from the driving sleeve 401, and a reversing push rod 205 is fixedly installed at the right end of the inner side of the inner fixed tube 201 by bolts, and the telescopic end of the reversing push rod 205 is fixedly connected with a synchronous shaft 404, and the synchronous shaft 404 is rotatably connected with the passive gear ring 206, and the reversing push rod 205 can drive the passive gear ring 206 to move left and right through the synchronous shaft 404;

[0040] More specifically, the reversing push rod 205 can directly transmit the force to the outer movable tube 212 through the synchronous shaft 404, the driving sleeve 401 and the sliding sleeve 405, and then the outer movable tube 212 squeezes the iron sand inside the inner spherical shell 103 through the squeezing block 210;

[0041] The bottom end of the reversing push rod 205 is fixedly connected to the driving motor 204 by bolts, and the output shaft of the driving motor 204 is fixedly connected to the driving gear 203 by bolts, and the driving gear 203 is meshed with the passive ring gear 206. Specifically, the width of the passive ring gear 206 is greater than the width of the driving gear 203, so that when the passive ring gear 206 moves left and right, the driving gear 203 can still drive the passive ring gear 206 to rotate;

[0042] A clamping strip 402 is fixedly installed on the outer surface of the right end of the central rod 209. A plurality of clamping grooves are formed at the inner end of the sliding sleeve 405, and the clamping grooves correspond to the clamping strip 402. When the sliding sleeve 405 moves to the right, the clamping block 403 on the left side of the sliding sleeve 405 disengages from the connection with the passive groove 406. At this time, the clamping grooves are butted against the outer surface of the clamping strip 402. Specifically, a limiting ring is fixedly installed at the inner end of the sliding sleeve 405, and the limiting ring is located on the left side of the clamping strip 402, so that the sliding sleeve 405 cannot disengage from the outer surface of the central rod 209.

[0043] As Figure 5 , Figure 7 , Figure 8 shown, a fixing ring 302 is fixedly installed at the inner end of the inner fixing tube 201. Conducting tubes 301 are fixedly connected to both the upper and lower ends of the fixing ring 302. Two through holes are formed on the outer surface of the extrusion block 210, and the through holes correspond to the two conducting tubes 301. The shape of the through holes is the same as that of the conducting tubes 301. A sealing rubber ring is sleeved on the outer surface of the conducting tube 301 and is in close fit with the inner wall of the through hole to improve the sealing performance. A guiding through hole 308 is formed on the outer surface of the conducting tube 301. After the conducting tube 301 moves to the left, the guiding through hole 308 is located inside the inner spherical shell 103, and the left end of the conducting tube 301 penetrates through the inside of the through hole. A conveying tube 108 is fixedly connected to the outer surface of the conducting tube 301. The output end of the conveying tube 108 passes through the inner fixing tube 201 and is fixedly connected to the electromagnetic shell 104. A synchronous sleeve 303 is sleeved on the outer surface of the outer movable tube 212. One end of the synchronous sleeve 303 away from the fixing ring 302 is rotatably connected to a synchronous ring 304. Movable blocks 306 are fixedly welded to both the upper and lower ends of the synchronous ring 304. One end of the movable block 306 close to the conducting tube 301 is fixedly connected to a screen 307 through an extension plate. Specifically, the holes on the outer surface of the screen 307 are smaller than the iron sand. The initial position of the screen 307 is located on the right side of the conveying tube 108. A snap ring 305 is sleeved on the outer surface of the synchronous sleeve 303, and the snap ring 305 is located on the right side of the synchronous ring 304. An outer adjusting sleeve 202 is sleeved at the inner end of the inner fixing tube 201, and the outer adjusting sleeve 202 is sleeved on the outer surface of the outer movable tube 212. The left end of the outer adjusting sleeve 202 is fixedly connected to the snap ring 305. An electric push rod 207 is fixedly installed at the inner end of the inner fixing tube 201 through bolts, and the telescopic end of the electric push rod 207 is fixedly connected to the outer adjusting sleeve 202;

[0044] Specifically, the snap ring 305 and the synchronous ring 304 are connected through a shock-absorbing washer to prevent the vibration generated during the movement of the outer movable tube 212 from affecting the outer adjusting sleeve 202 and further damaging the device.

[0045] As Figure 9As shown, the outer surface of the central rod 209 is provided with stirring blades 208. The outer surface of the central rod 209 is provided with threaded grooves 21, and the stirring blades 208 are threadedly sleeved on the outer surface of the threaded grooves 21. A limiting block is fixedly installed on the outer surface of the central rod 209. Therefore, the stirring blades 208 can only move left and right within a limited range. When the inner spherical shell 103 becomes hard as a whole and the iron sand is tightly attached and difficult to disperse, the central rod 209 rotates. The stirring blades 208 buried in the iron sand cannot rotate and will move to the right along the threaded grooves 21. Under the action of force, the extrusion block 210 is pushed to move to the right, and the iron sand is thus stressed from the inside and cracks. As the rotational force of the central rod 209 increases, the iron sand tightly attached inside the inner spherical shell 103 is finally dispersed. The diameter of the stirring blades 208 is smaller than the distance between the two conduction tubes 301.

[0046] The working principle of the present invention is:

[0047] During use, the mask 1 is fixed on the patient's face through the strap 3. Then, the device is started through the control terminal 2. The telescopic end of the reversing push rod 205 moves to the left, and the iron sand inside the inner spherical shell 103 is pressed more tightly. At the same time, the extension length of the reversing push rod 205 can be adjusted according to the patient's acceptance habit to adjust the iron sand with different tightness. To control the reversing push rod 205, at this time, the driving motor 204 drives the driven gear ring 206 to rotate through the driving gear 203. At this time, the driven gear ring 206 drives the driving sleeve 401 to rotate through the sliding sleeve 405, and then drives the outer movable tube 212 to move left and right through the corrugated teeth 213, thereby achieving the effect of vibration therapy;

[0048] If electromagnetic-assisted vibration therapy is to be used, after the electromagnetic coil 109 is powered on at this time, the effect of electromagnetic-assisted therapy is achieved while realizing vibration therapy, increasing blood flow in the facial area and improving blood supply to facial muscles;

[0049] If the electromagnetic strength is to be enhanced, since the number of turns of the electromagnetic coil 109 inside the electromagnetic shell 104 cannot be changed, the current strength can only be increased. At the same time, in order to avoid excessive consumption of the battery capacity after the current is enhanced, at this time, the reversing push rod 205 drives the sliding sleeve 405 to move to the right through the synchronous shaft 404. At this time, due to the action of the internal limit ring of the sliding sleeve 405, the center rod 209 also moves to the right, so that the center rod 209 drives the extrusion block 210 to move through the stirring blade 208. At this time, the conducting hole 308 on the outer surface of the conducting pipe 301 is exposed inside the inner spherical shell 103, and then the water pump 1 06 starts, the solenoid valve 110 opens, and water is pumped from the solenoid valve 110, making the iron sand inside the inner spherical shell 103 more active. Then the iron sand enters the interior of the electromagnetic shell 104 through the conducting pipe 301 and the conveying pipe 108. The electromagnetic coil 109 is energized immediately afterwards, but the current is not strong, so that the iron sand can adhere to the outer surface of the electromagnetic coil 109. Then, the output end of the electric push rod 207 drives the outer adjustment sleeve 202 to move, so that the screen 307 moves to the left and finally is located on the left side of the conveying pipe 108. At this time, the iron sand stops flowing into the interior of the electromagnetic shell 104, and only water flows through;

[0050] Since the current of the electromagnetic coil 109 is not large, the iron sand is uniformly attached to the outer surface of the electromagnetic coil 109 during the flow of water. Then, the current of the electromagnetic coil 109 gradually increases, making the magnetic force stronger. Since the overall diameter of the electromagnetic coil 109 becomes thicker, the iron sand can enhance the gathering and concentration of the magnetic lines of force and improve the penetration depth of the magnetic field to a certain extent.

[0051] If the iron sand inside the electromagnetic shell 104 is to be pumped back into the inner spherical shell 103, the above-mentioned action only needs to be performed in the opposite way: no current flows through the electromagnetic coil 109, so it loses its magnetism, the water pump 106 is started, and water is pumped through the water pipe 107 to activate the water flow inside the electromagnetic shell 104, so that the iron sand can flow with the water flow and flow back to the inner spherical shell 103 through the delivery pipe 108 and the conducting pipe 301.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
