Description

Technical Field

[0001] The present invention relates to the field of medical rehabilitation equipment, and in particular to a fatigue rehabilitation instrument and a rehabilitation system based on vibration and electrical stimulation of meridian acupoints. Background Art

[0002] With the increasing difficulty and intensity of the troops' diversified non-war military operations and actual combat military training, and the emergence of new combat modes such as special operations and individual combat, the physical requirements for officers and soldiers are constantly increasing. High-intensity military training is very likely to cause training fatigue, which affects the improvement of the army's combat effectiveness. In clinical frontline work, the comprehensive use of traditional Chinese medicine therapies such as acupuncture, electroacupuncture, and massage can significantly relieve officers and soldiers' training fatigue. However, traditional Chinese medicine acupuncture therapy is difficult for officers and soldiers to master and operate independently due to its percutaneous invasiveness, time-consuming treatment, and technical requirements for operators, which in turn affects the use and promotion of the advantages of Chinese medicine in serving the army's training fatigue. With the medical community's research on the rehabilitation treatment of motor function, the technology of electrical stimulation of meridian acupoints can quickly relieve training fatigue, stimulate meridian acupoints through low-frequency current pulses, and induce the relief of its motor nerves.

[0003] The prior art includes manually massaging acupoints or using massage rehabilitation instruments to massage human acupoints, such as the muscle care massage rehabilitation device disclosed in patent announcement number CN107028747A, which uses a thumping method for rehabilitation care; the shoulder, neck and back massager disclosed in patent announcement number CN210631479U uses a rolling ball massage device for massage. Most of the existing fatigue rehabilitation instruments are set for a certain part of the human body, with a narrow scope of application and poor practicality. None of the existing rehabilitation instruments can know the user's muscle fatigue status, and automatically and intelligently generate targeted massage plans based on the user's muscle fatigue status; although proper massage has certain benefits for the human body, if the massage force is too heavy, it may cause contusion of the human body's muscle soft tissue, aggravate the discomfort of the already tired body, and is not conducive to relaxing the body; therefore, how to set up a massage according to the degree of muscle fatigue is of great technical significance.

[0039] The following examples further illustrate the content of the present invention, but should not be construed as limiting the present invention. Without departing from the spirit and substance of the present invention, modifications or substitutions made to the methods, steps or conditions of the present invention all fall within the scope of the present invention.

[0040] The present invention provides a fatigue rehabilitation instrument based on vibration and electrical stimulation of meridian acupoints. Figure 1 As shown, it includes a flexible wearable belt body 1 and a control device 2 arranged in the belt body 1 or placed outside the belt body 1. The belt body 1 includes an airbag detection part, an electrical stimulation contact part and a vibration massage part. The airbag detection part includes a first folded airway 20 arranged in an annular manner on the belt body, and a plurality of airbag cavities 21 are evenly distributed along the first folded airway 20, and a muscle tension sensor 22 is provided on the outer surface of each airbag cavity 21; the electrical stimulation contact part includes a second folded airway 30 arranged in an annular manner on the belt body 1, the second folded airway 30 is arranged avoiding the first folded airway 20, and a plurality of small airbags 31 are evenly distributed along the second folded airway 30, and an electrode device 32 is provided on the outer surface of each small airbag 31; the vibration massage part is at least one vibration massage device 40 arranged avoiding the airbag detection part and the electrical stimulation contact part. In a specific solution, the second folded airway and the first folded airway are independent airways, and different airways can be controlled to be inflated and deflated.

[0041] The control device includes an air cylinder assembly 5 for respectively inflating and deflating the airbag cavity 21 and the small airbag 31, an electrode control unit for controlling the on and off of the electrode device, a massage control switch for controlling the vibration massage device, and a control module connected to these devices (including the air cylinder assembly, the control switch, etc.), the control module is configured to receive detection data from the detection device and generate a massage plan adapted to the current fatigue condition according to the detection data, and issue corresponding control instructions; the air cylinder assembly 5 is connected to the first fold-type airway 20 and the second fold-type airway 30 through the ventilation tube, respectively, to achieve independent control of the first fold-type airway 20 and the second fold-type airway 30. The control device can be entirely arranged inside or outside the belt body, such as Figure 2 The belt is shown as being arranged outside the belt body, and it can also be partially arranged inside or outside the belt body; the various components of the control device are adjusted according to the actual situation. In some specific technical solutions, the air cylinder assembly can be independent of the belt body through the ventilation pipe, the control module can be arranged outside the belt body or inside the belt body, and the belt age control switch and massage control switch are generally arranged on the belt body.

[0042] The surfaces of the airbag cavity 21 and the small airbag 31 in the inflated state are higher than the first folded airway 20 and the second folded airway 30, and also higher than the surface of the vibration massage device 40; the airbag inflation makes the detection sensor fit the human body muscle, thereby ensuring the accuracy of the detection data. Through this limitation, when sensor detection and electrode detection and treatment are required, the airbag cavity and the small airbag are inflated to make the sensors and electrode sheets at the corresponding parts completely and closely contact with the human skin, thereby achieving the desired purpose.

[0043] The first folded airway 20 extends to both ends of the belt body 1, which can better detect the muscle tension data of the covered position. The muscle tension sensor of the airbag cavity 21 adopts a pressure sensor, which is tied in a ring on the human limb to be detected during use, and detects the corresponding muscle tension in all directions. A temperature sensor can also be set on the side of each pressure sensor or several of the pressure sensors. During exercise, muscles will generate a lot of heat energy, causing the temperature to rise. When performing muscle testing, the temperature change of the muscles is monitored to better evaluate the muscle fatigue and recovery status.

[0044] In one example, the electrode sheets are connected and arranged in a detachable structure. Figure 3 As shown, a joint hole 33 is dug on the front side of the small airbag 31, and an insulating layer 34 is connected to the joint hole 33. An electrode plug hole 35 is provided on the insulating layer 34. An electrode connector 36 is provided inside the electrode plug hole 35. An annular columnar interface 38 is provided on the electrode connector 36 corresponding to the electrode plug hole 35. The annular columnar interface 6 is not higher than the electrode plug hole 35; an electrode plug pin 37 plugged into the annular columnar interface 38 is provided on the back of the electrode device 32. The electrode device 32 can be installed and disassembled as needed. When operating, the electrode device 32 can be directly inserted or pulled out from the annular columnar connector 38 of the electrode connector 36, which is convenient to use; the requirements of different users can be flexibly met through the disassembly and assembly of the electrode device.

[0045] Electromyography detection is to collect weak bioelectric signals, usually at the millivolt level, while electrical stimulation is to apply a larger current, which may reach tens of milliamperes; when using the same electrode, there may be problems with signal interference, such as the high voltage of the stimulation current will damage the front-end amplifier of the detection circuit. In addition, the stimulation signal may drown out the weak electromyographic signal, resulting in inaccurate detection. To this end, the present invention adopts a switching circuit to solve the above technical problems. The electrode control unit includes a switching circuit connected to the electrode device, an electromyographic detection circuit and an electrical stimulation circuit connected to the switching circuit, respectively. The switching circuit uses an analog switch to connect the switching circuit, and the electrical stimulation circuit includes an H-bridge drive circuit connected to the analog switch and an electrical stimulation generator connected to the H-bridge drive circuit. The switching circuit uses an analog switch or a relay to switch the connection of the electrode. In the detection stage, it is necessary to ensure that the electrode is completely disconnected from the stimulation circuit to avoid residual current affecting the signal quality; a protection circuit, such as a diode clamp or an optocoupler isolation, is used in the circuit to protect the detection circuit. The electrode device needs to select electrodes suitable for simultaneous stimulation and detection, such as using conductive gel, which can reduce contact impedance and improve signal quality; for example, using Ag / AgCl electrodes, which are commonly used in biological signal detection and have low noise and good stability.

[0046] In the specific circuit module design, such as Figure 4 As shown, the analog switch part can use a high-voltage switch such as ADG1414 to support high-voltage switching and ensure that the detection circuit is disconnected during stimulation. The front-end protection circuit can use a transient voltage suppressor diode (TVS) and an operational amplifier clamp circuit to limit the input voltage. The electromyographic signal amplification circuit requires a high-input impedance, low-noise instrumentation amplifier, such as AD8220, with a bandpass filter to remove interference. The electrical stimulation drive circuit requires an H-bridge structure, using a high-voltage MOSFET or an integrated driver such as DRV2605 to provide an adjustable current pulse. This circuit realizes that electromyographic signal detection and electrical stimulation share the same electrode, solving technical problems such as signal interference, safety isolation, and polarization effects.
