[0032] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with examples. It should be understood that the specific examples described herein are only used to explain the present application and are not used to limit the present application.

[0033] Example 1.

[0034] Reference Figure 1 , Figure 3As shown, a tongue muscle vibration and electric stimulation combined treatment instrument, comprising a main unit 1 and a tongue treatment head 2 assembled together, a main control unit 3 is arranged on the main unit 1, and a power management module 4, a vibration driving module 5, an electric stimulation generation module 6 and a control module 7 connected with the main control unit 3, a vibration array and an electrode array are arranged on the tongue treatment head, the vibration array is composed of several resonance motors 8, and the electrode array is composed of several surface electrode points 9.

[0035] Referring to Figure 4 , the tongue treatment head 2 comprises a tongue contact layer 201, a device layer 202, a circuit layer 203 and a support layer 204, the tongue contact layer 201 is used for transmitting mechanical vibration and electric current, the device layer 202 is used for arranging the vibration array and the electrode array, the circuit layer 203 is used for realizing the power supply circuit wiring of the vibration array and the electrode array, and the support layer 204 is used for forming structural support.

[0036] In the embodiment, the tongue contact layer 201 is preferably a medical-grade conductive silicone layer, which has high elasticity, low allergenicity and good surface touch, and protects the oral mucosa; in some embodiments, a conductive thermoplastic polyurethane layer can be used instead of the conductive silicone layer. At the same time, the outer surface of the tongue contact layer 201 is designed to accurately imitate the physiological curvature of the anterior 2 / 3 of the tongue dorsum of an adult or a child, which is “spoon-shaped” or “saddle-shaped” with a slightly concave middle part and smoothly raised sides, so as to ensure extensive, uniform and comfortable surface contact with the tongue surface, rather than point contact.

[0037] In the embodiment, the tongue contact layer 201 is overmolded, the device layer 202, the circuit layer 203 and the support layer 204 are embedded and fixed by the tongue contact layer 201, which ensures overall waterproofness (IPX7 level), can withstand high-temperature and high-pressure disinfection, all materials meet the ISO10993 biocompatibility standard, and electrical safety meets the IEC60601-1 medical electrical equipment standard.

[0038] The electrode array is preferably arranged in the central region and the front part of the tongue treatment head 2, corresponding to the main functional regions of the tongue muscles (such as genioglossus, tongue vertical muscle, etc.), so as to optimize the stimulation efficiency of electric current on the core muscle groups. The electrode points of the electrode array can be arranged in a matrix or a specific targeted manner.

[0039] The vibration array is preferably arranged around and between the electrode array, and can be additionally arranged in the corresponding area of the tongue root, so as to ensure uniform conduction of vibration and avoid “vibration dead angle”.

[0040] In this embodiment, the electrode array and the vibration array are fixed in the device layer 202 by embedded injection molding. In order to improve the insulation effect in the layer, a thin layer of insulating material (such as polyimide film, food-grade insulating paint) is preferably coated on the metal parts of the electrode array and the vibration array, and only the working surface of the electrode and the fixed contact of the vibration motor are exposed.

[0041] The circuit layer 203 is a flexible printed circuit board (FPC), and the wires of all electrode arrays and the wires of all vibration arrays are routed through different circuit layers on the FPC, fundamentally achieving circuit isolation.

[0042] The support layer 204 is a medical plastic part (such as an ABS part or a PEEK part), which forms the skeleton of the tongue treatment head 2. The support layer 204 has a wire channel inside and a standardized electrical interface such as a magnetic contact or a waterproof plug at the end, which is used for detachable connection with the main unit 1; so that different shapes of tongue treatment heads 2 can be replaced according to different user groups.

[0043] In this embodiment, the vibration array is composed of a plurality of linear resonant actuators (LRA), and the electrode array uses medical-grade stainless steel or gold-plated electrode points arranged in a matrix or target manner. The composite treatment instrument provided by the present application is powered by a lithium battery, such as a 3.7V, 500mAh or more rechargeable lithium battery. The power supply systems of the vibration array and the electrode array are independently designed but coordinated and managed by the same main control unit, which is preferably a micro control unit (MCU).

[0044] Referring to Figure 2 As shown, the power supply mode of the vibration array is that the main control unit 3 provides a system voltage of 3.3V or 5V to the vibration driving module 5 through the power management module 3, and outputs an alternating voltage of a specific frequency and amplitude to the linear resonant actuator (LRA) through the vibration driving module 5. In this embodiment, the vibration driving module 5 is preferably a DRV2605 haptic driving chip, which is controlled by the I2C or SPI bus of the MCU and can accurately output complex vibration waveforms such as continuous, pulse, and gradual change.

[0045] The power supply mode of the electrode array is that the main control unit 3 raises the voltage to tens of volts through the boost circuit of the power management module 3 to provide the electric stimulation generation module 6 with sufficient voltage margin to overcome the skin impedance, and the electric stimulation generation module 6 has a constant current control and waveform generation circuit to output a coupling current. In this embodiment, the use of a constant current control and waveform generation circuit to output a coupling current can ensure stable current output and avoid burning due to the dramatic fluctuation of the current output with the change of the skin impedance.

[0046] It should be noted that the specific circuit diagram in the power management module, the peripheral circuit diagram of the DRV2605 tactile driving chip, and the circuit diagram of the constant current control and waveform generation circuit are ordinary technical knowledge mastered by those skilled in the art, and will not be described here.

[0047] In this embodiment, the main unit 1 is set as a handheld type, which is convenient for carrying and operation. In some embodiments, the main unit 1 can also be set as a neck hanging type or a small desktop type.

[0048] The tongue muscle vibration and electric stimulation combined therapeutic instrument provided in this embodiment has a simple mode and a professional mode. In the simple mode, several commonly used treatment programs are preset: 1) a pure vibration program for muscle relaxation and proprioceptive stimulation; 2) a pure electric stimulation mode for neuromuscular activation and muscle strength training; and 3) a combined mode in which vibration and electric stimulation are performed synchronously or alternately in a preset sequence to achieve synergistic effect. In the professional mode, a therapist or a senior user can finely adjust all parameters (frequency, pulse width, intensity, timing, etc.) through a special mobile phone APP or computer software connected through Bluetooth, so as to realize targeted exercise at home. In particular, the main control unit can store multiple user profiles and corresponding exercise programs through a storage device, which facilitates multi-user use at home or individual disease management.

[0049] In some embodiments, the combined therapeutic instrument is connected to a rehabilitation management system based on a cloud platform through a network, and a therapist remotely sets and adjusts a program for a home patient through the rehabilitation management system, and patient data is automatically uploaded for efficacy evaluation.

[0050] In some embodiments, the main control and calculation functions are borne by a mobile phone APP.

[0051] In some embodiments, the tongue muscle vibration and electric stimulation combined therapeutic instrument also has a unilateral mode, in which the vibration array and the electrode array on the tongue treatment head are designed to be independently controlled in left and right zones, which is used for targeted training of unilateral tongue muscle weakness patients.

[0052] In one embodiment, the electric stimulation intensity is controlled by slow rising and slow falling, and the electric stimulation intensity is automatically slowly raised and lowered at the beginning and the end to avoid sudden stimulation.

[0053] In one embodiment, the start of electric stimulation is controlled by double keys, and only when two safety keys are pressed at the same time can the electric stimulation mode be started to prevent accidental touch.

[0054] In one embodiment, the main control unit has a treatment time limit, and when the single treatment time or the cumulative use time per day reaches the set upper limit value, the main control unit automatically controls the combined therapeutic instrument to stop working to prevent overuse.

[0055] The tongue muscle vibration and electric stimulation combined therapeutic instrument provided by the embodiment has the following technical advantages:

[0056] 1) The professional tongue muscle electric stimulation and physical vibration function are integrated in a portable device that can be safely operated by non-professionals for the first time, which breaks down the barriers between hospital treatment and home rehabilitation. Through the spatiotemporal cooperation of physical vibration and neuromuscular electric stimulation, "peripheral sensory input enhancement" (vibration) and "central motor pathway activation" (electric stimulation) can be realized simultaneously, which can theoretically more effectively promote neural plasticity and improve the proprioception, muscle strength and coordination of the tongue muscle, and the curative effect is better than that of a single mode.

[0057] 2) The bionic flexible tongue treatment head is creatively designed, and the bionic and conformal contact surface greatly improves the comfort; at the same time, the vibration array and the electrode array are conformally integrated on the three-dimensional curved surface, and the comfortable, effective and non-invasive combined treatment is realized.

[0058] 3) The simple mode and professional mode dual-mode control architecture is adopted, which guarantees the safety and convenience of home use, retains the flexibility of professional adjustment, takes into account the safety and convenience and precise treatment, makes long-term home rehabilitation possible, and specially considers the long-term, home, self-management treatment needs of patients with progressive swallowing disorders (such as fibrosis after radiotherapy). In some implementations, a miniature temperature sensor and a heating element are also integrated on the tongue treatment head 2 to provide warm stimulation and promote local blood circulation, which is especially suitable for fibrotic tissue.

[0059] 4) Safety and reliability: multiple insulation design, real-time impedance monitoring, constant current source output and other multiple safety protection mechanisms ensure the electrical safety and biological safety of oral use.

[0060] 5) Economic and social benefits: reduces the continuous dependence of patients on professionals and medical institutions, and is expected to shorten the hospitalization period and reduce the overall rehabilitation cost.

[0061] Embodiment two.

[0062] The tongue muscle vibration and electric stimulation combined therapeutic instrument provided by the embodiment is basically the same as that of embodiment one, and the difference lies in that the main unit is a neck hanging type structure, and a surface electromyography (sEMG) sensor in contact with the skin of the pharynx is arranged on the main unit. The electromyography signal detected by the surface electromyography sensor is used to judge whether the patient tries to make tongue movement, and auxiliary electric stimulation is given when it is judged that the patient tries to make tongue movement, so as to realize "triggered stimulation" and achieve better rehabilitation effect.

[0063] Embodiment three.
