Description

Wearable stimulation device for deep layer muscles of abdomen and waist

The invention relates to an active wearable stimulation device for the deep layer muscles of the abdomen and waist, which can strengthen the deep layer muscles of the abdomen and waist and increase the motion control ability of the abdomen and waist.

Currently, there are generally devices that can stimulate the muscles of the abdomen or waist of the human body. For example, there is a US Invention Publication No. US20160140866. It discloses a tactile input for improving body movement, which is mainly used to prompt the user to coordinate proper muscle contraction during a certain form of body movement such as exercise. The system includes a belt with protrusions facing inwardly. The protrusions are suitable for contact with the user's skin, and prompt the user through tactile feedback or by auditory, visual or vibration. Promote proper muscle contraction. In operation, when the user generates muscle expansion during exercise, the muscle expansion can apply a predetermined level of pressure to the protrusion. After the protrusion receives the pressure, it outputs a pressure signal through the transducer to obtain a specific part of the user. According to the above-mentioned pressure signal, sound, light or vibration prompts are generated to avoid the user’s improper posture from causing muscle damage. However, the above-mentioned protrusions are used to receive the pressure exerted by the muscles, and are not used to provide active stimulation to the user's muscles.

There is also the US Invention Announcement No. US9526946. It is to disclose a system and method for providing treatment and evaluation using vibro-tactile feedback, mainly by providing vibro-tactile feedback to the user to treat imbalance and balance disorders. The invention includes a vibrating tactile belt attached to the waist of the user. The vibrating tactile belt includes a plurality of actuators distributed at intervals, and a plurality of actuators work together for communication. Through the skin to stimulate the tactile response, the user can be guided to move or exercise in the correct posture through tactile perception. The above-mentioned actuator stimulates the user through different changes in pulse and time, so as to prompt the user to adopt the correct posture during exercise. Although the brake disclosed in the invention is worn on the waist of the user, it only uses vibration to provide tactile warnings and is not used to stimulate the user’s deep muscles. At the same time, the brake only sees frequency and time control, not Expose control parameters such as movement stroke, thrust and reciprocating frequency.

There is also a new patent case No. M550157 "Low Frequency Infrasonic Therapy Device" announced on October 11, 106 of the Republic of China, which discloses: a host and a primary sonic booster. The host has a primary sonic frequency generating unit that can generate one Or more than one frequency signal of the infrasonic frequency; the infrasonic pusher is electrically connected to the host, and receives the frequency signal transmitted by the host to emit the infrasound of the frequency. The infrasound waves generated by the physiotherapy device are energy waves and vibration waves in the form of sine waves. The frequency range can be adjusted according to different body parts and purposes of use. If a deeper or wider range of purposes is required, the frequency can be applied. Lower output; if you want to use a shallower and concentrated range of use effects, apply a higher frequency. With the fluctuating energy of the low-frequency infrasound waves, the physiotherapy device can provide soothing and regulating functions to the human body, and can provide shallow and deep permeation to the human body.

However, the previous case of the patent uses low-frequency infrasound waves to produce superficial and deep penetration of muscles, and cannot specifically stimulate deep muscles.

There is also a patent case of Invention No. 201626953 "Waist Vibration Signal Generator" published on August 1, 105 of the Republic of China, which discloses: including a main body, a vertical vibration signal generator, a control unit, and a power supply unit And a hanging department. The main body has a first axis, a vertical vibration signal generator is arranged inside the main body, and the vertical vibration signal generator includes a voice coil motor and a flexible membrane, both of which are arranged along the first axis; the voice coil motor is provided There is a permanent magnet, a coil and a pair of coil connecting wires; when the control part supplies a direct current system to the pair of coil connecting wires to make the coil generate a magnetic field and force the permanent magnet to move along the first axis, the position of the permanent magnet is moved by Coil connection wires produce different voltage changes And make the permanent magnet produce a pushing and moving force on the flexible film. It can be used for those who need to shrink the abdomen from time to time and maintain the posture. When the lower abdomen is slack for a while, the protruding lower abdomen will push the flexible membrane. At this time, the pressure detection module can detect this through the pair of coil connecting wires. The pressure received by the flexible membrane is generated and the pressure value is transmitted back to the central control module. When the central control module captures the pressure value, it determines that the pressure value is greater than the pushing threshold and continues After a working time, the vertical vibration signal generator is controlled to generate a warning pressing rhythm along the first axis.

Because the previous case of the patent uses a voice coil motor, the permanent magnet can be controlled to drive the flexible film to correspond to the human body, repeatedly pushing and shrinking, to produce a vibration rhythm perpendicular to the waist skin direction. And use the pressure detection module to sense the reverse pressure change of the permanent magnet through the flexible film when the lower abdomen is protruding. Suppress the rhythm. Since the previous patent application does not use a voice coil motor to stimulate deep muscles, and also does not disclose control parameters such as movement stroke, thrust, and reciprocating frequency, it is obviously different from the technical features of the present invention.

In view of this, in view of the current use of abdominal and waist stimulation devices have the above-mentioned shortcomings.

From the tenth and eleventh figure, it can be seen that when the multifidus muscle [MF] contracts, its thickness and cross-sectional area increase, and after the S mode is administered, the increase in muscle activation is significantly better than that of the V mode, V mode It is better than the N mode. Therefore, it can be proved that the wearable stimulation device of the present invention can increase the activation of the deep muscles of the abdomen or waist.

Therefore, it can be proved that the wearable stimulation device of the present invention has a shallower effect on the abdomen or waist. Layer muscles will not have a particularly noticeable effect.

The above test results prove that the wearable stimulation device of the present invention can only stimulate the deep muscles of the abdomen or waist, such as the transversus abdominis muscle (TrA) in the abdomen and the multifidus muscle (MF) in the waist, which increases the activation of deep muscles. .
