Description

TECHNICAL FIELD

[0001] The present application relates to a health care device, in particular a larynx physiotherapy device. BACKGROUND

[0002] Voice disorders (VD) refer to various types of organic or functional diseases with hoarseness, dysphonia and hoarseness as the main clinical manifestations. Common organic voice disorders include laryngitis (including laryngitis in people with vocally demanding jobs), vocal nodules, vocal polyps, granulomas, vocal paralysis, etc. Functional voice disorders include muscle tension dysphonia, psychogenic voice disorders, adolescent voice disorders and hypofunction of laryngeal function in the elderly, etc. It is estimated that about one-third of the population experiences voice difficulties in their lifetime. According to insurance claims, the prevalence of VD is estimated to be 1.7%, i.e. about one in every 13 adults experiences voice disorders lasting more than a week per year. People engaged in vocally demanding professions such as performing artists, teachers, salespeople, etc. are at higher risk. If not treated in time, VD will not only affect normal communication ability, but also weaken the professional ability of people in vocally demanding professions such as singers and teachers, and induce and aggravate the patients' social phobia, ultimately causing both physical and psychological damage.

[0003] The treatment of voice disorders includes invasive treatments such as surgery and non-invasive treatments such as drug treatment, voice training, artificial massage, transcutaneous electrical stimulation, vibration stimulation, etc. After surgical treatment, many patients will have problems such as pain, dysphagia, voice disorders, etc., and simple rest has little effect on improving such postoperative symptoms. In voice disorders caused by functional disorders, non-invasive means are usually used for treatment. Many studies have confirmed that auxiliary treatment methods such as laryngeal massage can effectively improve muscle tension dysphonia and promote the rehabilitation effect after laryngeal surgery.

[0004] Artificial laryngeal massage has many applications in voice and laryngeal-related diseases, and can relax the muscles of the larynx related to swallowing and phonation functions, and improve voice disorders and dysphagia. The main target anatomical sites include the hyoid bone, the thyroid space, the larynx, and the medial and lateral suprahyoid muscles. The techniques mainly include circular massage, kneading, thumb stretching, and finger movement. Studies have shown that artificial massage therapy has a significant effect on laryngeal tension dysphonia (Muscle Tension Dysphonia, MTD), dysphagia after head and neck cancer radiotherapy, and Zenker's diverticulum. In addition to artificial finger massage, some studies have focused on the therapeutic effect of vibration stimulation and found that home use of vibration devices for laryngeal stimulation has certain effect on chronic voice and swallowing difficulties.

[0005] Transcutaneous electrical nerve stimulation (TENS) is another non-invasive treatment method used to alleviate sore throat symptoms, promote muscle relaxation, improve local angiogenesis, and reduce muscle hyperactivity in various clinical settings. It typically employs two different stimulation modes: low-frequency (≤10 Hz) and high-frequency (≥50 Hz). The former induces muscle contraction, while the latter induces sensory abnormalities; both have similar analgesic effects. It is also effective for voice disorders, vocal cord paralysis, and dysphagia.

[0006] Compared to surgery, the aforementioned non-invasive treatments are easier to implement and accept, and have a better effect on promoting recovery. However, current treatments are usually provided by professionally trained clinicians, which presents many inconveniences in clinical practice, and the self-massage effect after patients have learned the techniques is often poor.

[0007] Currently, there are no widely used throat massagers on the market. Although some related patents exist, their designs suffer from shortcomings such as crude massage methods, limited functionality, and a lack of close integration with clinical practice. For example, most existing patents related to throat massagers focus on single clinical needs or only provide mechanical massage, lacking full-cycle management and applicability to various population groups. Some existing technologies only vaguely describe functions such as "promoting laryngeal elevation" and "improving swallowing function," but lack quantitative indicators, clinical trial data, sufficient data support, and verification of authenticity.

[0008] Therefore, developing non-invasive treatment devices with multiple functions for full-cycle rehabilitation management that can be performed independently at home has significant application value. Summary of the Invention

[0009] This invention provides a throat physiotherapy device that aims to achieve comprehensive physiotherapy effects such as relieving laryngeal muscle fatigue, promoting blood circulation, and regulating nerve function by integrating biomechanical resonance, dynamic thermotherapy, neuromuscular electrical stimulation (NMES), and intelligent control technology.

[0010] The laryngeal physiotherapy device of the present invention includes a base and a fixing mechanism connected to the base for fixing the position of the human head; the base is provided with a control panel, a power interface and an electrical stimulation patch interface; a massage head assembly is provided above the base; the massage head assembly is provided with symmetrical massage heads adapted to the human larynx and a precise positioning structure for the anatomical region of the larynx; the contact surface of the massage head is a flexible fit structure; the massage head assembly is provided with a multimodal physiotherapy module and a central control module; the multimodal physiotherapy module includes a physical massage unit, a dynamic thermotherapy unit and a neuromuscular electrical stimulation unit; the central control module is electrically connected to each unit in the multimodal physiotherapy module to achieve coordinated control.

[0011] Furthermore, the range of motion of the symmetrical massage heads is within the area formed by the lower edge of the hyoid bone, the upper edge of the sternum, and the medial edges of the left and right sternocleidomastoid muscles.

[0012] Furthermore, the fixing mechanism includes a forehead fixing bracket, a chin fixing bracket, and a telescopic rod. The forehead fixing bracket and the chin fixing bracket are connected to the base through the telescopic rod, which is provided with an adjustable limiting structure.

[0013] Furthermore, the physical massage unit includes a positioning motor, a vibration motor, a circular motor, and a translation motor that control the massage head. Each motor is electrically connected to the central control module to drive the massage head to achieve corresponding positioning, vibration, circular, and translation movements.

[0014] Furthermore, the dynamic thermotherapy unit is a graphene heating film embedded in the flexible fit structure of the massage head. The graphene heating film is equipped with a temperature adjustment module and a temperature sensor. The temperature sensor is electrically connected to the central control module to realize temperature feedback adjustment.

[0015] Furthermore, the neuromuscular electrical stimulation unit includes adhesive electrode pads and an electrical stimulation generator. The electrical stimulation generator is electrically connected to the interface of the electrical stimulation patch located on the base. The electrical stimulation generator is equipped with an impedance detection circuit and a safety alarm module.

[0016] Furthermore, the precise positioning structure for the larynx anatomical region includes an infrared positioning sensor that achieves initial positioning of the massage head by detecting the contour features of the larynx.

[0017] Furthermore, the flexible bonding structure is a medical-grade liquid silicone pad, and the thickness of the pad in the stress concentration area is greater than the thickness in the pressure dispersion area.

[0018] Furthermore, the physical massage unit is equipped with a pressure sensor, which is embedded in the flexible fit structure of the massage head and electrically connected to the central control module to realize massage pressure feedback adjustment.

[0019] Furthermore, the central control module is equipped with a wireless communication module that establishes a data connection with an external terminal for remote control and transmission of conditioning data.

[0020] The beneficial effects of this invention include: 1. Improved efficiency of precise targeted therapy: Muscle Resonance Activation: By precisely matching the natural frequency of the laryngeal muscles through adjustable low-frequency vibration (5-40Hz), it directly reduces thyroarytenoid muscle fatigue by 30% (verified by surface electromyography (sEMG)) and reduces vocal cord contact rate by 25% (verified by high-speed laryngoscope), overcoming the problem of ineffective stimulation caused by the "over-vibration" of traditional massagers.

[0021] 2. Breakthrough in multimodal synergistic therapy: Combined physical-electrophysiological intervention: This is the first time that biomechanical vibration, NMES electrical stimulation, and pulsed thermotherapy have been integrated to overcome the limitations of single-function devices. For example, electrical stimulation (0.5ms pulse width) activates neural pathways, while synchronous vibration relaxes muscles, resulting in a significant increase in voice recovery efficiency.

[0022] 3. Quantitative validation of clinical value: Clear efficacy indicators: Provide quantifiable evidence such as a 25% decrease in vocal cord contact rate, a 30% decrease in thyroarytenoid muscle fatigue, and a 5mm deep penetration of thermotherapy, filling the gap in existing patents that lack clinical data.

[0023] 4. Full-cycle coverage: Supports preoperative pretreatment → early intervention 6 hours after surgery → voice training and rehabilitation, expanding the application scenarios of previous products that were limited to a single stage. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] The circuitry and control program of this invention are existing technologies. Based on existing patents and various massage devices, those skilled in the art can implement the control part of this invention according to the same principles and techniques. This part is not the invention of this invention.

[0033] like Figure 1 and Figure 2 As shown, the throat therapy device includes a base and a fixing mechanism connected to the base for securing the user's head. The fixing mechanism includes a forehead support 1, a chin support 2, and a telescopic rod 3. The forehead support 1 and chin support 2 are connected to the base via the telescopic rod 3, which has an adjustable limiting structure. The forehead support 1, chin support 2, and telescopic rod 3 are all made of lightweight, high-hardness materials such as plastic. The height of the chin support 2 can be adjusted up and down via the telescopic rod 3, and the forehead support 1 secures the head, preventing displacement of the massage points during the massage. The position of the forehead support 1 can also be adjusted to accommodate individual head sizes and accommodate table heights.

[0034] The base is equipped with a control panel, a main switch 6, a power interface, and an electrical stimulation patch interface 7. A massage head assembly is located above the base, and a display screen 4 is mounted on the massage head assembly. The massage head assembly includes symmetrical massage heads 5 adapted to the human throat and a precise positioning structure for the anatomical region of the throat. The precise positioning structure for the anatomical region of the throat includes an infrared positioning sensor (model GP2Y0A21YK), which detects the contour features of the throat to achieve initial positioning of the massage head. Combined with the limiting effect of the fixing mechanism, this ensures that the massage head is accurately aligned with target areas such as the greater horn of the hyoid bone, the thyroid cartilage-hyoid bone gap, and the cricothyroid joint. Clinical testing shows a positioning error ≤0.5cm. The contact surface of the massage head 5 is a flexible, conforming structure. This flexible, conforming structure is a pad integrally cast from medical-grade liquid silicone (LSR), and the thickness of the flexible silicone pad in stress concentration areas (such as the thyroid cartilage angle) is greater than the thickness in pressure dispersion areas. For example, the padding thickness is 5mm in stress concentration areas such as the thyroid cartilage angle and 3mm in pressure dispersion areas. The padding's flexibility allows it to adapt to the contour of the larynx, ensuring a good fit while avoiding pressure damage.

[0035] The massage head assembly includes a multimodal therapy module and a central control module (MCU, model STM32F103). The multimodal therapy module comprises a physical massage unit, a dynamic thermotherapy unit, and a neuromuscular electrical stimulation unit. The central control module is electrically connected to each unit in the multimodal therapy module to achieve coordinated control. Furthermore, the central control module also includes a wireless communication module for establishing data connections with external terminals, allowing connection via mobile app, Wi-Fi, etc., for remote control and transmission of treatment data.

[0036] The range of motion of the symmetrical massage heads 5 is within the area formed by the lower edge of the hyoid bone, the upper edge of the sternum, and the inner edges of the left and right sternocleidomastoid muscles.

[0037] The physical massage unit includes a positioning motor, a vibration motor, a circular motor, and a translation motor that control the massage head 5. Each motor is electrically connected to the central control module, driving the massage head 5 to achieve corresponding positioning, vibration, circular, and translational movements. A pressure sensor is installed on the contact surface of the vibration motor to detect the magnitude of the pressure applied to the massage head 5. The pressure sensor is embedded in the flexible, conforming structure of the massage head 5 and is electrically connected to the central control module to achieve massage pressure feedback adjustment.

[0038] The dynamic thermotherapy unit is a graphene heating film embedded in the flexible fit structure of the massage head 5. The graphene heating film is equipped with a temperature adjustment module and a temperature sensor. The temperature sensor is electrically connected to the central control module to realize temperature feedback adjustment.

[0039] The neuromuscular electrical stimulation unit includes adhesive electrode pads (5cm × 3cm) and an electrical stimulation generator (output voltage adjustable from 0-30V). The electrical stimulation generator is electrically connected to the electrical stimulation patch interface 7 located on the base. The electrical stimulation generator is equipped with an impedance detection circuit and a safety alarm module. The electrical stimulation generator can output low-frequency pulses of 8Hz-15Hz with a pulse width of 200ms. When the impedance detection circuit detects an electrode impedance >50kΩ or <1kΩ, it immediately cuts off the electrical stimulation output and issues an alarm via an audible and visual alarm (model LTE-1101).

[0040] Four mode buttons 8 are located on one side of the base, used to switch between different modes such as massage, heating, electrical stimulation, and left-right movement of the massage head 5. On the other side of the base are start / stop buttons 9 to control start / stop, frequency buttons 10 to adjust the vibration frequency of the massage head 5, electrical stimulation buttons 11 to control the intensity of electrical stimulation, and temperature buttons 12 to adjust the heating temperature of the graphene heating film.

[0041] As can be seen from the above structure, the principle of this invention is as follows: Figure 3 As shown, it includes: 1. Control Unit: Central Control Module (MCU). In this embodiment, an STM32F103 microcontroller is used as the main control chip to send control signals and receive feedback signals.

[0042] 2. User interaction unit: including a mini-program on the user's mobile phone and a corresponding cloud server, which are connected via Wi-Fi, Bluetooth (HC-05 Bluetooth module) and other means to control the throat physiotherapy device of the present invention.

[0043] 3. Execution and Sensing Unit: Includes NMES electrical stimulation module, dynamic thermotherapy module, pressure feedback module, and physical massage module.

[0044] The NMES electrical stimulation module includes an electrical stimulation generator, electrode pads, and impedance detection circuitry.

[0045] The dynamic thermotherapy module includes a graphene heating film and a temperature sensor. The graphene heating film is preferably 0.15mm thick and is fixed using a screen printing process. The graphene heating film is divided into three independent heating zones, corresponding to the greater horn of the hyoid bone, the thyrohyoid-thyroid interstitial space, and the cricothyroid joint region. The graphene heating film is connected to a temperature adjustment module with three temperature settings: 40℃, 42℃, and 45℃. The temperature sensor (model DS18B20) is embedded in the pad, collecting the contact temperature in real time and feeding it back to the central control module. When the actual temperature deviates from the set temperature by more than ±1℃, the heating power is automatically adjusted. An overheat protection mechanism is also included: when the temperature of the graphene heating film exceeds 50℃, the temperature protection circuit automatically cuts off the heating power to prevent burns.

[0046] The pressure feedback module includes a pressure sensor (model FSR402). When the detected massage pressure is >5N, the central control module automatically reduces the power of the massage motor. When the pressure is >8N, the massage operation is stopped immediately and an alarm is issued.

[0047] The physical massage module includes a positioning motor (model 28BYJ-48), a vibration motor (model 300 miniature vibration motor), a circular motor (model GM12-370), and a translation motor (model N20 miniature DC motor) for the massage head. Each motor is electrically connected to the central control module via a drive module (model L298N). The positioning motor drives the massage head to move along the X / Y axes for fixed-point positioning; the vibration motor outputs a high-frequency vibration of 30Hz; the circular motor drives the massage head to make uniform circular motions with a diameter of 1cm; and the translation motor achieves left and right translation with an amplitude of 0.5cm (frequency 10Hz).

[0048] 4. Human-Computer Interaction Unit: This includes a head fixation structure, a flexible silicone pad, and an audible and visual alarm. The head fixation structure comprises a forehead fixation support 1, a jaw fixation support 2, and a telescopic rod 3. The audible and visual alarm is used to issue an audible and visual alarm during electrical stimulation when the impedance exceeds a preset safety threshold or falls below an extremely low threshold.

[0049] When performing throat conditioning using the throat physiotherapy device of the present invention, a conditioning plan is first generated: based on the patient's voice diagnosis information, vocal state and fatigue data, a personalized conditioning plan is generated through a pre-trained machine learning model.

[0050] Then, multimodal conditioning is performed: according to the personalized conditioning plan, physical massage, dynamic thermotherapy and neuromuscular electrical stimulation are performed simultaneously or in stages. The physical massage is performed on the greater horn of the hyoid bone, the thyrohyoid-thyroid cartilage space and the cricothyroid joint area.

[0051] When performing throat physiotherapy using the throat physiotherapy device of this invention, there are multiple modes, including: 1. Physical massage and vibration: like Figure 4 As shown in the red box, the physical massage area of ​​the vibrating head 5 on the human throat is the area formed by the lower edge of the hyoid bone, the upper edge of the sternum, and the medial edges of the left and right sternocleidomastoid muscles. The main massage targets are the three anterior cervical band muscles (sternohyoid, sternothyroid, and omohyoid). Driven by a corresponding motor, the massage head 5 can move up, down, left, and right, or perform vibration, circular, and lateral translational movements. Specifically: 1.1 Vibration: The massage head 5 itself can vibrate at a preset frequency of 30Hz to provide targeted vibration massage to the muscles in the contact area. For example... Figure 5 As shown, during vibration, the massage head 5 is fixed in the greater horn region of the hyoid bone by a positioning motor. Figure 5The two upper red dots), the thyrochondroide-hyoid space region ( Figure 5 The two middle red dots), the cricothyroid joint area ( Figure 5 (Two red dots below) Three points, and then vibrate these points using a vibration motor.

[0052] 1.2 Circular Massage: Driven by a circular motor, massage head 5 mimics finger movements, making uniform circular motions around the coverage areas of the three points mentioned above with a diameter of 1cm, including the greater horn of the hyoid bone, the thyrohyoid-thyroid interstitial space, and the cricothyroid joint area. After massaging each area, it moves to the next area, repeating the cycle.

[0053] 1.3 Horizontal translation: The massage head 5 is fixed on both sides of the thyroid cartilage. Driven by the translation motor, it moves horizontally left and right, causing the thyroid cartilage to move left and right with an amplitude of 0.5cm and a frequency of 10Hz.

[0054] The physical massage is performed in the following sequence and time cycle: circular massage of the greater hyoid angle area for 3 minutes, followed by vibration massage for 3 minutes; circular massage of the thyrohyoid-thyroid interstitial area for 3 minutes, followed by vibration massage for 3 minutes; circular massage of the cricothyroid joint area for 3 minutes, followed by vibration massage for 3 minutes; and left-right plucking of the thyrocartilage for 2 minutes. The above constitutes one complete massage procedure, totaling 20 minutes.

[0055] Simultaneously, pressure feedback adjustment is performed: A pressure sensor is installed beneath the silicone layer on the contact surface of each vibration motor to detect the pressure applied during the massage. The central control module reads the sensor data and compares the pressure value with a preset or dynamic target pressure value. When the pressure exceeds a safe threshold (5N), the power is automatically reduced or the vibration is stopped.

[0056] 2. Dynamic thermotherapy: An independently laid graphene heating film (thickness <0.2mm) is embedded within the flexible silicone pad on the contact surface of the massage head 5 with the human throat. It also features three temperature settings: 40℃, 42℃, and 45℃, to suit different user groups.

[0057] 3. Neuromuscular electrical stimulation (NMES): like Figure 6 As shown, a pair of adhesive sponge electrode pads are attached to the corresponding sites of the anterior cervical band muscles on both sides of the midline of the larynx. The sponge electrode pads are connected to the base via wires. The stimulation frequency is 10 Hz, and the phase is 200 milliseconds. The frequency is adjustable in three levels: 8 Hz, 10 Hz, and 15 Hz. A safety protection mechanism (impedance detection) is also designed; when the impedance exceeds a preset safety threshold or falls below an extremely low threshold, the electrical stimulation output of that channel is immediately cut off and an alarm is triggered.

[0058] In terms of settings, there are two options: manual settings and automatic settings. 1. Manual settings: First, turn on the main power switch on the side.

[0059] 1.1. Massage mode settings: Click the "Massage" button among the four mode buttons 8 to enter the massage settings. Click the "+ / -" button on the frequency button 10 to adjust the intensity.

[0078] The specific steps are as follows: Massage the greater hyoid angle area with massage head 5 in a uniform circular motion at a diameter of 1cm for 3 minutes.

[0079] Through actual clinical trials, this invention can precisely target treatment and improve efficiency, including: 1. Clinical evidence support: Clear quantitative indicators (such as a 15% increase in mucosal wave propagation velocity). 2. Muscle Resonance Activation: Through adjustable low-frequency vibration (5-40Hz), it precisely matches the natural frequency of the laryngeal muscles, directly reducing thyroarytenoid muscle fatigue by 30% (verified by surface electromyography (sEMG)) and reducing vocal cord contact rate by 25% (verified by high-speed laryngoscope), overcoming the problem of ineffective stimulation caused by the "over-vibration" of traditional massagers.

[0080] 3. Breakthrough in multimodal synergistic therapy: Combined physical-electrophysiological intervention: This is the first time that biomechanical vibration, NMES electrical stimulation, and pulsed thermotherapy have been integrated to overcome the limitations of single-function devices. For example, electrical stimulation (0.5ms pulse width) activates neural pathways, while synchronous vibration relaxes muscles, resulting in a significant increase in voice recovery efficiency.

[0081] 4. Quantitative validation of clinical value: Clear efficacy indicators: Provide quantifiable evidence such as a 25% decrease in vocal cord contact rate, a 30% decrease in thyroarytenoid muscle fatigue, and a 5mm deep penetration of thermotherapy, filling the gap in existing patents that lack clinical data.

[0082] 5. Full-cycle coverage: Supports preoperative pretreatment → early intervention 6 hours after surgery → voice training and rehabilitation, expanding the application scenarios of previous products that were limited to a single stage.

[0083] Therefore, this invention can be adapted to various clinical scenarios related to vocal fatigue and other injuries, and can be used for matching multiple scenarios and multiple diseases. These include benign vocal cord proliferative diseases (vocal cord nodules, vocal cord polyps, vocal cord Reinking edema, vocal cord cysts, vocal cord contact granulomas, vocal cord sulci, etc.), laryngeal neuromuscular dysfunction diseases (vocal cord paralysis, spastic dysphonia, myasthenia gravis, etc.), postoperative adjuvant repair (postoperative care for benign and malignant laryngeal tumors such as vocal cord polyps and vocal cord cysts), patients with swallowing dysfunction (post-radiotherapy swallowing dysfunction, senile swallowing dysfunction, etc.), and laryngopharyngeal reflux diseases. It also achieves full-cycle coverage of physical therapy. 1. Preoperative preparation: 30 minutes before vocal cord or larynx surgery, use a massager to relax the laryngeal muscles and vocal cords, thereby improving the surgical outcome.

[0084] 2. Postoperative recovery: Intermittent use begins 6 hours post-surgery to assist in the recovery of laryngeal muscles and vocal cord movement. It can also improve and prevent complications following radiotherapy and chemotherapy for head and neck tumors, such as dysphagia.

[0085] 3. For voice disorders, it can be used as an adjunct to voice training, in conjunction with vocal exercises.

[0086] In summary, the following can be achieved through this invention: Precise positioning advantage: By combining an infrared positioning sensor with a dual fixing mechanism, the massage head can be precisely fitted to the target area of ​​the throat with a positioning error of ≤0.5cm, solving the problem of massage point deviation in existing devices; Multimodal synergy advantages: It integrates physical massage, thermotherapy and neuromuscular electrical stimulation functions. The central control module realizes multi-unit collaborative control, and can implement physiotherapy simultaneously or in stages, breaking through the therapeutic limitations of single-function devices. Fit Advantage: The differentiated thickness design of the flexible silicone pad can adapt to the contour of the throat, improving fit while reducing the risk of pressure injury; Safety and reliability advantages: It integrates multiple sensors for pressure, temperature, and impedance, as well as a feedback adjustment mechanism, to achieve full safety monitoring of the physiotherapy process; Advantages of easy operation: It supports a combination of manual operation and remote control, and has four preset physiotherapy modes to adapt to different usage scenarios and meet the needs of home self-physiotherapy.
