Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a portable facial muscle strength trainer. Background Art

[0002] Facial nerve paralysis is a common disease, also known as facial palsy. It is a nerve deficiency symptom in which damage to the facial nerve leads to paralysis of the facial muscles. Facial paralysis is divided into peripheral facial nerve paralysis and idiopathic facial nerve paralysis. Among them, idiopathic facial nerve paralysis is the most common, accounting for about 70% of all facial nerve paralysis patients.

[0003] At present, the treatment method for idiopathic facial nerve paralysis is a combination of acupuncture and facial muscle strength training. Facial muscle strength training includes opening the mouth, pouting, etc., which can stimulate the facial nerves and muscles and speed up the patient's recovery. However, the existing facial muscle strength trainers are large in size and inconvenient to carry. Patients need to go to the hospital to use them, which is very inconvenient. Therefore, a portable facial muscle strength trainer is needed to facilitate patients to perform facial muscle strength training anytime and anywhere. Summary of the invention

The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0005] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a portable facial muscle strength trainer, including a handle, a limit ring fixed on the handle, an electric control mechanism fixed on the handle, an inflation mechanism fixed on the handle, and a training mechanism fixed on the handle; The training mechanism includes a first cavity fixed on the handle, a first slide groove symmetrically fixed on the handle, a second slide groove fixed on the handle, a second bite component slidably arranged on the first slide groove and the second slide groove, a third slide groove fixed on the handle, a fourth slide groove fixed on the handle and connected to the third slide groove, and a first bite component slidably arranged on the third slide groove and the fourth slide groove.

[0006] Specifically, the electric control mechanism includes a battery fixed on the handle, an electric control board fixed on the handle, and a plurality of buttons fixed on the handle.

[0007] Specifically, the first bite assembly includes a first connecting rod slidably arranged on the third slide groove and the fourth slide groove, a first sliding block fixedly arranged on the first connecting rod, a first bite plate fixedly arranged on the first connecting rod, a first yielding groove fixedly arranged on the first bite plate, a first rotating shaft symmetrically fixedly arranged on the first bite plate, and a first auxiliary training device fixedly arranged on the first bite plate.

[0008] Specifically, the second bite assembly includes a second base plate slidably arranged on the first slide groove and the second slide groove, a second sliding block symmetrically fixed on the first base plate, a fifth slide groove fixed on the second base plate, a second connecting rod slidably arranged on the fifth slide groove, a second bite plate rotatably sleeved on the first rotating shaft, a third connecting rod fixed on the second bite plate, a locking device fixed on the second connecting rod and the third connecting rod, a second auxiliary training device fixed on the second bite plate, and a second yield groove fixed on the second bite plate.

[0009] Specifically, the first auxiliary training device includes a first base fixed at one end of the first bite plate, a sixth slide groove symmetrically arranged on the first base, a first shell slidably arranged on the sixth slide groove, a third slider symmetrically fixed on the first shell, and a first airbag fixed on the first base.

[0010] Specifically, the locking device includes a yield groove fixed on the second connecting rod, a protrusion fixed on the third connecting rod, a mounting groove fixed on the protrusion, a locking groove fixed on the second connecting rod, a locking block slidably arranged on the mounting groove, and a spring with one end fixed on the locking block and the other end fixed on the protrusion.

[0011] Specifically, the second auxiliary training device includes a second base fixedly arranged at one end of the second bite plate, a seventh slide groove symmetrically arranged on the second base, a second shell slidably arranged on the seventh slide groove, a fourth slider symmetrically fixedly arranged on the second shell, and a second airbag fixedly arranged on the second base.

[0012] Specifically, the inflation mechanism includes a motor fixed on the handle, a rotating shaft fixed on the motor, a fifth slider symmetrically fixed on the rotating shaft, a push plate sleeved on the fifth slider and the rotating shaft and sliding along the fifth slider and the rotating shaft, a second cavity fixed on the handle, an eighth slide groove fixed on the second cavity, a ninth slide groove fixed on the second cavity, a sixth slider symmetrically fixed on the push plate, a connecting component fixed on the second cavity, and a third airbag fixed on the first cavity.

[0013] Specifically, the connecting component includes a first hose fixed on the handle and located on one side of the second cavity, a second hose fixed on the handle and located on one side of the second cavity, a third hose with one end fixed on one side of the second cavity and the other end fixed on the third airbag, a fourth hose with one end fixed on one side of the second cavity and the other end fixed on the first airbag, and a fifth hose with one end fixed on one side of the second cavity and the other end fixed on the second airbag.

[0014] The beneficial effects of the present invention are: (1) The force arm of the third airbag applying resistance is from the third airbag to the rotating shaft, and the force arm when the user bites is from the second bite plate to the rotating shaft. The bite force arm is smaller than the resistance force arm. Therefore, for the inflation mechanism, only a small amount of inflation is needed to apply a large resistance. A small amount of inflation means that the motor does not need to work for a long time, which is more energy-efficient, making the device have a longer battery life and more portable. At the same time, a small amount of inflation also means that the second base plate does not need to rotate a large angle or move a long distance, making the device smaller and more portable.

[0015] (2) The second bite plate is mounted on the rotating shaft and rotates, and its movement trajectory matches the movement trajectory of the lower jaw when the mouth is opened, simulating the actual movement of the lower jaw during speaking and chewing, which can improve the training effect.

[0016] (3) Compared with two bite plates set in parallel, when the user bites, the angle between the teeth and the bite plate is not perpendicular. When the user bites, there is an angle between the direction of the force applied by the teeth on the bite plate and the direction of movement of the bite plate. The force applied by the user's bite does not completely act on the movement of the bite plate. When using this device, the lower teeth are always perpendicular to the second bite plate. When biting, the direction of the force applied by the teeth on the second bite plate is always collinear with the direction of rotation of the bite plate, so that the force applied by the user's bite completely acts on the rotation of the second bite plate, making it easier for the user to exert force and achieving better training effect.

When in use, the first connecting rod needs to be pulled outward to make the first slider enter the third sliding groove from the fourth sliding groove, and then the first connecting rod is rotated to make the first connecting rod rotate in the third sliding groove, so as to make the first bite plate in a horizontal state. At this time, the fourth sliding groove will limit the first slider, so that the first slider cannot slide into the fourth sliding groove, that is, the training mechanism will not be pushed by external force to slide on the sliding groove during training. When it needs to be stored, the first connecting rod is rotated to align the first slider with the fourth sliding groove, and the first connecting rod is pushed inward to complete the storage; the first bite plate contacts the upper teeth and upper lip; the first give way groove is arranged in the center of the first bite plate, which is convenient for the user to put the tongue; the first auxiliary training device can assist the user in pouting training.

[0029] Specifically, the first auxiliary training device includes a first base 5761 fixed at one end of the first occlusal plate, a sixth slide groove 5762 symmetrically arranged on the first base, a first shell 5763 slidably arranged on the sixth slide groove, a third slider 5764 symmetrically fixed on the first shell, and a first airbag 5765 fixed on the first base; the first shell slides on the sixth slide groove through the third slider, and the first shell contacts the patient's upper lip; the first airbag can be inflated to push out the first shell, and the user needs to overcome the thrust of the first airbag on the first shell when performing pouting training, that is, increase the resistance of the user during pouting training and improve the training effect; at the same time, the inflation amount of the first airbag can be controlled to control the size of the resistance, which is suitable for users at different training stages; the first airbag is provided with an electrically controlled valve for deflation.

[0030] Specifically, the locking device includes a yield groove 5471 fixed on the second connecting rod, a protrusion 5472 fixed on the third connecting rod, a mounting groove 5473 fixed on the protrusion, a locking groove 5474 fixed on the second connecting rod, a locking block 5475 slidably arranged on the mounting groove, and a spring 5476 with one end fixed on the locking block and the other end fixed on the protrusion; when the first connecting rod rotates, the first bite plate will rotate accordingly. Since the first bite plate and the second bite plate are connected by a rotating shaft, the second bite plate will also rotate accordingly and drive the locking block to rotate. When the locking block contacts the second connecting rod, the second connecting rod squeezes the locking block, causing the locking block to enter the yield groove and the spring to be squeezed. When rotated to 90°, the spring pushes the locking block into the locking groove.

[0031] Specifically, the second auxiliary training device includes a second base 5481 fixed on one end of the second occlusal plate, a seventh slide groove 5482 symmetrically arranged on the second base, a second shell 5483 slidably arranged on the seventh slide groove, a fourth slider 5484 symmetrically fixed on the second shell, and a second airbag 5485 fixed on the second base; the second shell slides on the seventh slide groove through the fourth slider, and the second shell contacts the patient's upper lip; the second airbag can be inflated to push out the second shell, and the user needs to overcome the thrust of the second airbag on the second shell when performing pouting training, that is, increase the resistance of the user during pouting training and improve the training effect; at the same time, the inflation amount of the second airbag can be controlled to control the size of the resistance, which is suitable for users at different training stages; the second airbag is provided with an electrically controlled valve for deflation.

[0032] Specifically, the inflation mechanism includes a motor 41 fixed on the handle, a rotating shaft 42 fixed on the motor, a fifth slider 43 symmetrically fixed on the rotating shaft, a push plate 44 sleeved on the fifth slider and the rotating shaft and sliding along the fifth slider and the rotating shaft, a second cavity 45 fixed on the handle, an eighth slide 46 fixed on the second cavity, a ninth slide 47 fixed on the second cavity, a sixth slider 48 symmetrically fixed on the push plate, a connecting component 49 fixed on the second cavity, and a third airbag 40 fixed on the first cavity; the starting points of the eighth slide and the ninth slide are 180° apart. The sixth slider is completely fitted with the eighth and ninth sliders, and the sixth slider is fixed on the push plate. The eighth and ninth sliders limit the movement trajectory of the push plate. The rotation of the motor drives the rotating shaft to rotate, and drives the push plate to rotate through the fifth slider. The push plate rotates and squeezes the air on one side, and inflates the third airbag through the connecting component to rotate the second bottom plate, thereby driving the second bite plate to rotate, and finally driving the user to open his mouth to realize the function of mouth opening training. At the same time, the user can bite the first bite plate and the second bite plate, and the gas in the third airbag will exert resistance on the second bottom plate, that is, increase the resistance when the user bites, and further train the facial muscles. ; The force arm of the third airbag applying resistance is from the third airbag to the rotating shaft, and the force arm when the user bites is from the second bite plate to the rotating shaft. The bite force arm is smaller than the resistance force arm. Therefore, for the inflation mechanism, only a small amount of inflation is needed to apply a large resistance. A small amount of inflation means that the motor does not need to work for a long time, which is more energy-efficient, making the device have a longer battery life and more portable. At the same time, a small amount of inflation also means that the second bottom plate does not need to rotate a large angle or move a long distance, making the device smaller and more portable. When the user is in use, the second bite plate rotates on the rotating shaft, and the movement trajectory is the same as the lower jaw when the mouth is opened. The motion trajectory fits the jaw movement during actual speaking and chewing. If there are two bite plates set in parallel, the angle between the teeth and the bite plate is not perpendicular when the user bites. There is an angle between the direction of the force applied by the teeth to the bite plate when the user bites and the direction of the bite plate movement. The force applied by the user's bite does not completely act on the movement of the bite plate. When using this device, the lower teeth are always perpendicular to the second bite plate. When biting, the direction of the force applied by the teeth on the second bite plate is always collinear with the direction of rotation of the bite plate, so that the force applied by the user's bite is completely applied to the rotation of the second bite plate, making it easier for the user to exert force and achieving better training effect.

[0033] Specifically, the connecting component includes a first hose 491 fixed on the handle and located at one side of the second cavity, a second hose 492 fixed on the handle and located at one side of the second cavity, a third hose 493 with one end fixed on one side of the second cavity and the other end fixed on the third airbag, a fourth hose 494 with one end fixed on one side of the second cavity and the other end fixed on the first airbag, and a fifth hose 495 with one end fixed on one side of the second cavity and the other end fixed on the second airbag; the first hose connects the second cavity with the outside; the second hose connects the second cavity with the outside; and electrically controlled valves are provided on the first hose and the second hose.
