Description

Technical Field

[0001] This invention relates to the field of sleep aid technology, and more specifically, to a home-based sleep quality optimization aid device for patients with chronic diseases. Background Technology

[0002] With the aging population, the number of patients with chronic diseases such as hypertension, diabetes, cardiovascular and cerebrovascular diseases, and chronic obstructive pulmonary disease continues to rise. Due to impaired physical function and the effects of their diseases, this group commonly experiences sleep problems such as disordered sleep structure, difficulty falling asleep, frequent awakenings at night, and abnormal sleep breathing. Their sleep quality is far below normal levels, and poor sleep can negatively impact disease control and physical recovery, severely reducing the effectiveness of recovery and even posing a potential threat to their lives.

[0003] Current sleep quality optimization solutions for patients with chronic diseases, particularly home-use assistive devices, suffer from significant design flaws and functional limitations. Existing electrical stimulation sleep aids are not tailored to the physiological characteristics and ear canal environment of chronic disease patients. The electrodes are prone to generating continuous heat, causing low-temperature skin burns, and they cannot intelligently adjust the stimulation mode according to the patient's sleep state. This makes it difficult to achieve effective vagus nerve stimulation during the sleep onset phase, to avoid electrode overheating risks during deep sleep, and to quickly intervene in fragmented sleep, thus failing to meet the home-use sleep optimization needs of chronic disease patients. Therefore, there is an urgent need for a home-use sleep quality optimization assistive device for chronic disease patients to address these issues. Summary of the Invention

[0004] In response to the problems in related technologies, this invention proposes a home-based sleep quality optimization assistive device for patients with chronic diseases, in order to overcome the aforementioned technical problems existing in the existing related technologies.

[0005] The technical solution of this invention is implemented as follows:

[0006] A home-based sleep quality optimization assistive device for chronic disease patients includes an adjustment controller and a wire. One end of the wire is provided with an earplug body, and one end of the earplug body is covered with a rubber sleeve. The outer circumferential wall of the earplug body is provided with an elastic strip for fitting the patient's concha cavity.

[0007] One side of the elastic strip is provided with a detection component for detecting the patient's sleep state and a stimulation component for optimizing the patient's sleep quality.

[0008] The stimulation component includes an outer sleeve fixedly connected to the elastic strip, an inner sleeve fixedly connected inside the outer sleeve, a first electrode disposed inside the outer sleeve, and a second electrode disposed inside the inner sleeve. A mating groove is formed on the bottom outer wall of the first electrode, and a conductive rod is fixedly connected to the circumferential outer wall of the second electrode. The conductive rod is slidably connected to the mating groove. A release groove is formed on the top outer wall of the first electrode, and the release groove communicates with the mating groove. The inner diameter of the release groove is larger than the diameter of the conductive rod.

[0009] The inner sleeve is equipped with a disengagement component to improve patient comfort.

[0013] As a further embodiment of the present invention: the protective component includes a first receiving groove formed inside the outer sleeve, a first spring fixedly connected to the top inner wall of the first receiving groove, a first slider fixedly connected to the bottom end of the first spring, a first temperature-controlled memory spring fixedly connected to the bottom outer wall of the first slider, a first thermally conductive silicone sheet fixedly connected to the end of the first temperature-controlled memory spring away from the first slider, a first sliding groove formed on the circumferential inner wall of the first receiving groove, a sliding rod slidably connected inside the first sliding groove, and the two ends of the sliding rod being fixedly connected to the first electrode and the first slider, respectively.

[0015] As a further embodiment of the present invention: both the first thermally conductive silicone sheet and the second thermally conductive silicone sheet are frustoconical in shape. A first thermally conductive cylinder is fixedly connected to the top of the first thermally conductive silicone sheet, and a second thermally conductive cylinder is fixedly connected to the top of the second thermally conductive silicone sheet. The first temperature-controlled memory spring is in contact with the inner circumferential wall of the first thermally conductive cylinder, and the second temperature-controlled memory spring is in contact with the inner circumferential wall of the second thermally conductive cylinder. The thickness of both the first thermally conductive cylinder and the second thermally conductive cylinder gradually decreases along the direction closer to the second electromagnet.

[0016] As a further embodiment of the present invention: a first heat insulation groove is provided at the bottom of the first receiving groove, a first heat insulation gap is formed between the outer circumferential wall of the first thermally conductive silicone sheet and the inner circumferential wall of the first heat insulation groove, a second heat insulation groove is provided at the bottom of the second receiving groove, a second heat insulation gap is formed between the outer circumferential wall of the second thermally conductive silicone sheet and the inner circumferential wall of the second heat insulation groove, a first protrusion is provided on the bottom outer wall of the first thermally conductive silicone sheet, and a second protrusion is provided on the bottom outer wall of the second thermally conductive silicone sheet.

[0017] As a further embodiment of the present invention: the outer circumferential wall and the inner circumferential wall of the inner sleeve are respectively provided with a first assembly groove and a second assembly groove that are distributed in a circular pattern at equal intervals. The first assembly groove and the second assembly groove are staggered. A first extension electrode and a second extension electrode are respectively inserted into the interior of the first assembly groove and the second assembly groove.

[0018] As a further embodiment of the present invention: the detection component includes a mounting groove formed on the outer wall of one side of the elastic strip, a third electrode is fixedly connected inside the mounting groove, and a heat dissipation groove is formed at the bottom of the third electrode, the heat dissipation groove being distributed in a honeycomb pattern through both ends of the third electrode.

[0019] As a further embodiment of the present invention: a heat dissipation hole is provided at the end of the elastic strip away from the third electrode, the cross-section of the heat dissipation hole is stepped, and one end of the heat dissipation hole is connected to the mounting groove.

[0020] The beneficial effects of this invention are:

[0021] This invention provides a home-based sleep quality optimization aid for patients with chronic diseases. By setting up a detection component and a stimulation component working in synergy, a third electrode is used to precisely collect physiological signals such as the patient's sleep state and heart rate fluctuations through continuous contact with the skin of the concha using a microampere-level working current. This provides a reliable basis for the device's intelligent control. Based on the detection results, the first and second electrodes are activated during the patient's sleep stage. These electrodes, along with the staggered first and second extension electrodes, provide sufficient electrical stimulation to the vagus nerve in the concha. Simultaneously, the device can promptly capture fragmented sleep signals that are common in patients with chronic diseases, quickly driving the electrodes back to normal stimulation. This effectively improves sleep problems such as difficulty falling asleep, frequent awakenings at night, and insufficient deep sleep duration in this population, breaking the vicious cycle of poor sleep quality and slow recovery. It effectively optimizes the sleep quality of patients with chronic diseases at home, aiding in physical recovery.

[0022] This invention provides a home-based sleep quality optimization aid for patients with chronic diseases. It features a double-layer protective structure formed by a disengagement component and a protection component. Combined with a frustum-shaped first and second thermally conductive silicone sheet and a heat-conducting cylinder of varying thickness, it achieves directional and efficient heat transfer from the skin to the temperature-controlled memory spring. The heat insulation gap between the protrusions at the bottom of the thermally conductive silicone sheet and the insulation groove further enhances the accuracy of temperature sensing. During use, the device provides dual-temperature-level protection: a 37.2°C trigger to disengage the second electrode for cooling, and a 37.9°C trigger to force the entire electrode to disengage and stop heating. This effectively cuts off the source of heat generation from the electrodes, preventing low-temperature burns to the delicate ear canal skin of patients with chronic diseases due to continuous overheating of the electrodes. Simultaneously, the honeycomb-shaped heat dissipation grooves of the third electrode and the stepped heat dissipation holes on the elastic strip form an airflow channel, achieving efficient heat dissipation of the detection electrodes. Overall, this comprehensively improves the safety and comfort of wearing the device.

[0023] This invention provides a home-based sleep quality optimization aid for patients with chronic diseases. Through a fitted structure design of the earplug, rubber sleeve, and elastic strip, the rubber sleeve enhances ear canal fit, while the elastic strip tightly conforms to the concha cavity for secure fixation. This design adapts to the ear canal structure characteristics of different patients with chronic diseases, offering strong stability and no noticeable foreign body sensation during home use. Electrode detachment and repositioning are achieved through the synergistic action of a temperature-controlled memory spring, an electromagnet, and a reset spring, resulting in rapid and smooth response. The detachment groove on the first electrode effectively prevents the conductive rod from remaining in contact with it after detachment, ensuring device stability. The device is easy to operate; patients can independently put it on and turn it off. After use, turning off the device automatically resets the electrodes. The single-electrode low-power operating mode effectively reduces energy consumption and extends usage time. The overall design is ingenious and intelligent, perfectly suited to the home-based needs of patients with chronic diseases. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0040] Please see Figures 1-12 A home-based sleep quality optimization assistive device for chronic disease patients includes an adjustment controller 1 and a wire 2. One end of the wire 2 is provided with an earplug body 3, and one end of the earplug body 3 is covered with a rubber sleeve 4. The outer circumference of the earplug body 3 is provided with an elastic strip 5 for fitting the patient's concha cavity.

[0041] One side of the elastic strip 5 is provided with a detection component for detecting the patient's sleep state and a stimulation component for optimizing the patient's sleep quality;

[0042] The stimulation component includes an outer sleeve 6 fixedly connected to an elastic strip 5, an inner sleeve 8 fixedly connected inside the outer sleeve 6, a first electrode 7 disposed inside the outer sleeve 6, a second electrode 9 disposed inside the inner sleeve 8, a mating groove 16 formed on the bottom outer wall of the first electrode 7, a conductive rod 15 fixedly connected to the circumferential outer wall of the second electrode 9, the conductive rod 15 being slidably connected to the mating groove 16, and a release groove 42 formed on the top outer wall of the first electrode 7, the release groove 42 being connected to the mating groove 16, the inner diameter of the release groove 42 being larger than the diameter of the conductive rod 15;

[0043] The inner sleeve 8 is equipped with a disengagement component to improve patient comfort.

[0044] The outer sleeve 6 is equipped with a protective component to prevent the first electrode 7 and the second electrode 9 from overheating.

[0045] Preferably, the disengagement assembly includes a second receiving groove 44 formed inside the inner sleeve 8. A second spring 38 is fixedly connected to the top inner wall of the second receiving groove 44. A second slider 39 is fixedly connected to the bottom end of the second spring 38. A second temperature-controlled memory spring 47 is fixedly connected to the bottom of the second slider 39. A second thermally conductive silicone sheet 12 is fixedly connected to the end of the second temperature-controlled memory spring 47 away from the second slider 39. A sliding post 40 is fixedly connected to the outer circumferential wall of the second slider 39. The end of the sliding post 40 away from the second slider 39 is fixedly connected to the top outer wall of the second electrode 9. The second receiving groove 44 has a second sliding groove 45 on its inner circumferential wall. One end of the sliding column 40 passes through the inside of the second sliding groove 45. The outer circumferential wall of the sliding column 40 is slidably connected to both inner walls of the second sliding groove 45. A second electromagnet 27 is fixedly connected inside the inner sleeve 8. A support frame 31 is fixedly connected to the top outer wall of the second electrode 9. A second metal plate 29 is fixedly connected to the top of the support frame 31. When the patient is asleep, the detection component detects that the electrode is continuously working and generating heat, causing the ear temperature to reach the safe threshold (greater than 37.2℃) for removal from the component. The second temperature control memory... The force of spring 47 increases, causing the second slider 39 to rise and compress the second spring 38. As the second slider 39 moves upward, it causes the sliding column 40 and the second electrode 9 to rise together. When the second electrode 9 raises its top metal plate 29 to the attraction area of ​​the second electromagnet 27, the second electromagnet 27 instantly applies an upward attraction to the second metal plate 29, causing the second electrode 9 to rise rapidly. When the second metal plate 29 adheres to the bottom of the second electromagnet 27, the conductive rod 15 also rises to disengage from the slot. In step 42, since the inner diameter of the detachment groove 42 is larger than the diameter of the conductive rod 15, the second electrode 9 is completely detached from the first electrode 7 and stops being powered. At this time, only the second electrode 9 continues to work, thereby significantly reducing the overall heat generation of the electrode, quickly relieving the temperature rise inside the patient's concha, and avoiding low-temperature burns caused by the electrode continuously heating up and contacting the skin. At the same time, the single-electrode low-power working mode does not interrupt the basic gentle stimulation of the vagus nerve, and can reduce the interference with the patient's deep sleep and reduce the power consumption of the entire device, taking into account both wearing safety and sleep stability.

[0046] Preferably, the protective component includes a first receiving groove 41 formed inside the outer sleeve 6. A first spring 36 is fixedly connected to the top inner wall of the first receiving groove 41. A first slider 35 is fixedly connected to the bottom end of the first spring 36. A first temperature-controlled memory spring 34 is fixedly connected to the bottom outer wall of the first slider 35. A first thermally conductive silicone sheet 10 is fixedly connected to the end of the first temperature-controlled memory spring 34 away from the first slider 35. A first sliding groove 32 is formed on the circumferential inner wall of the first receiving groove 41. A sliding rod 37 is slidably connected inside the first sliding groove 32. The two ends of the slide bar 37 are fixedly connected to the first electrode 7 and the first slider 35, respectively. The top outer wall of the first electrode 7 is fixedly connected to support columns 30 that are evenly spaced and distributed in a circular pattern. The top of the support columns 30 is fixedly connected to the first metal plate 28. The inside of the outer sleeve 6 is fixedly connected to the first electromagnet 26. When the detection component detects that the temperature inside the patient's concha is greater than 37.9°C, the protection component will be activated immediately. The first temperature-controlled memory spring 34 will deform under force, and the force will increase, causing the first slider 35 to slide upward and compress the first spring 36. The first slider 35 synchronously pulls the slider 37 and the first electrode 7 upwards. When the first electrode 7 drives the first metal plate 28 at the top to rise to the attraction area of ​​the first electromagnet 26, the first electromagnet 26 instantly generates magnetic attraction and applies an upward attraction force to the first metal plate 28, driving the first electrode 7 to rise quickly to the designated position, so that the first electrode 7 is completely detached from the patient's concha skin. At this time, neither the first electrode 7 nor the second electrode 9 of the device is in contact with the patient's skin, cutting off all heat sources from the root and quickly reducing the temperature inside the concha. This avoids damage such as low-temperature burns to the delicate ear canal skin of patients with chronic diseases caused by continuous temperature rise. This protection component is the last line of defense against overheating of the device. Together with the detachment component, it forms a dual-temperature graded protection. 37.2℃ triggers single electrode detachment and heat reduction, and 37.9℃ triggers full electrode forced detachment and heat stoppage. It takes into account the sleep-aid intervention needs during deep sleep and can make a rapid and thorough protective response when overheating risks occur. It is adapted to the physical state and ear canal environment of patients with chronic diseases during sleep, greatly improving the safety and compatibility of the device.

[0047] Preferably, both the first thermally conductive silicone pad 10 and the second thermally conductive silicone pad 12 are frustoconical. Because both are frustoconical, heat can be drawn from the skin of the patient's concha to the first temperature-controlled memory spring 34 and the second temperature-controlled memory spring 47. A first heat-conducting cylinder 33 is fixedly connected to the top of the first thermally conductive silicone pad 10, and a second heat-conducting cylinder 46 is fixedly connected to the top of the second thermally conductive silicone pad 12. The first temperature-controlled memory spring 34 contacts the inner circumferential wall of the first heat-conducting cylinder 33, and the second temperature-controlled memory spring 47 contacts the inner circumferential wall of the second heat-conducting cylinder 46. The thickness of both the first heat-conducting cylinder 33 and the second heat-conducting cylinder 46 gradually decreases along the direction close to the second electromagnet 27. At the same time, the structural design of the first heat-conducting cylinder 33 and the second heat-conducting cylinder 46 gradually thinning along the direction close to the second electromagnet 27 can avoid the situation where the outer circumferential wall of the first heat-conducting cylinder 33 and the second heat-conducting cylinder 46 makes large-area contact with the inner wall of the receiving groove, which would lead to heat loss. This further improves the efficiency and accuracy of heat conduction, allowing the first temperature-controlled memory spring 34 and the second temperature-controlled memory spring 47 to quickly sense the temperature change in the concha cavity, providing timely and accurate temperature signals for the subsequent electrode removal action.

[0048] Preferably, a first heat-insulating groove 43 is formed at the bottom of the first receiving groove 41, and a first heat-insulating gap is formed between the outer circumferential wall of the first thermally conductive silicone sheet 10 and the inner circumferential wall of the first heat-insulating groove 43. A second heat-insulating groove 48 is formed at the bottom of the second receiving groove 44, and a second heat-insulating gap is formed between the outer circumferential wall of the second thermally conductive silicone sheet 12 and the inner circumferential wall of the second heat-insulating groove 48. Through the action of the first heat-insulating groove 43 and the second heat-insulating groove 48, the lateral heat loss can be effectively reduced. The outer wall is provided with a first protrusion 11, and the bottom outer wall of the second thermally conductive silicone sheet 12 is provided with a second protrusion 13. The first protrusion 11 and the second protrusion 13 at the bottom of the first thermally conductive silicone sheet 10 and the second thermally conductive silicone sheet 12 can ensure close contact with the skin, effectively eliminate the air layer and make the heat conduction more direct. Then, through the first thermally conductive cylinder 33 and the second thermally conductive cylinder 46 connected to the top of the thermally conductive silicone sheet, the heat is directionally and efficiently conducted to the contact parts of the first temperature control memory spring 34 and the second temperature control memory spring 47.

[0049] Preferably, the outer and inner circumferential walls of the inner sleeve 8 are respectively provided with a first mounting groove 19 and a second mounting groove 20 distributed in equal distances in a circular pattern. The first mounting groove 19 and the second mounting groove 20 are staggered. A first extension electrode 17 and a second extension electrode 18 are respectively inserted into the first mounting groove 19 and the second mounting groove 20. The first extension electrode 17 is fixedly connected to the first electrode 7, and the second extension electrode 18 is fixedly connected to the second electrode 9. By staggering the first mounting groove 19 and the second mounting groove 20 distributed in equal distances in a circular pattern on the outer and inner circumferential walls of the inner sleeve 8, and correspondingly inserting the first extension electrode 17 and the second extension electrode 18 connected to the first electrode 7 and the second electrode 9, the stable assembly of the extension electrodes is achieved. At the same time, the staggered distribution structure expands the coverage of electrical stimulation of the vagus nerve in the concha, making the stimulation more sufficient and uniform, and effectively improving the sleep-aiding effect of vagus nerve stimulation.

[0050] Preferably, the detection component includes a mounting groove 24 formed on the outer wall of one side of the elastic strip 5. A third electrode 21 is fixedly connected inside the mounting groove 24. A heat dissipation groove 22 is formed at the bottom of the third electrode 21. The heat dissipation groove 22 is distributed in a honeycomb pattern through both ends of the third electrode 21. A heat dissipation hole 23 is formed at the end of the elastic strip 5 away from the third electrode 21. The cross-section of the heat dissipation hole 23 is stepped. One end of the heat dissipation hole 23 is connected to the mounting groove 24. During the operation of the third electrode 21, the honeycomb-shaped hollow heat dissipation groove 22 formed at both ends can not only significantly reduce the contact area between the electrode and the skin and reduce heat generation, but also form an air circulation channel with the stepped heat dissipation hole 23 on the elastic strip 5 to achieve rapid heat dissipation. This avoids the detection electrode from overheating and affecting the wearing comfort and detection accuracy, and provides accurate basis for the intelligent control of the device.

[0051] In summary, with the help of the above-mentioned technical solution of the present invention, when in use, patients with chronic diseases first insert the end of the earplug body 3 covered with the rubber sleeve 4 into the ear canal, and then fix it by the elastic strip 5 on the outer wall of the earplug body 3 against the patient's concha cavity. After the patient wears it stably, the adjustment controller 1 is turned on and the device enters the working state. At this time, the third electrode 21 of the detection component is in contact with the skin of the concha cavity with a microampere working current throughout, which can effectively collect physiological signals such as the patient's sleep state and heart rate. At the same time, during the operation of the third electrode 21, the honeycomb-shaped hollow heat dissipation grooves 22 opened at both ends can not only greatly reduce the contact area between the electrode and the skin and reduce heat generation, but also form an air circulation channel with the stepped heat dissipation holes 23 on the elastic strip 5 to achieve rapid heat dissipation, avoid the detection electrode from overheating and affecting the wearing comfort and detection accuracy, and provide accurate basis for the intelligent control of the device.

[0052] Subsequently, when the detection component detects that the patient is in the sleep stage, the stimulation component is activated, and the first electrode 7 and the second electrode 9 simultaneously provide electrical stimulation to the vagus nerve in the patient's concha cavity. The two electrodes achieve stable conductivity through the sliding engagement of the conductive rod 15 and the mating groove 16. Furthermore, the interconnected first extension electrode 17 and the second extension electrode 18 further expand the stimulation range due to their staggered distribution, thereby enabling more thorough stimulation of the vagus nerve in the patient's concha cavity and a more significant sleep-aiding effect.

[0053] Simultaneously, the protection component and the disengagement component in this device enter the working preparation state. The first thermally conductive silicone pad 10 and the second thermally conductive silicone pad 12 in the protection component and the disengagement component can accurately collect the temperature inside the ear in real time. Since the first thermally conductive silicone pad 10 and the second thermally conductive silicone pad 12 are both frustoconical, heat can be "converged" from the skin of the patient's concha to the first temperature-controlled memory spring 34 and the second temperature-controlled memory spring 47. With the help of the first temperature-insulating groove 43 and the second temperature-insulating groove 48, lateral heat loss can be effectively reduced. Furthermore, the first protrusion 11 and the second protrusion 13 at the bottom of the first thermally conductive silicone pad 10 and the second thermally conductive silicone pad 12 can ensure tight contact with the skin. The tight fit effectively eliminates air gaps, making heat conduction more direct. The first heat-conducting cylinder 33 and the second heat-conducting cylinder 46, connected to the top of the heat-conducting silicone sheet, conduct heat in a directional and efficient manner to the contact area of ​​the first temperature-controlled memory spring 34 and the second temperature-controlled memory spring 47. At the same time, the structure design of the heat-conducting cylinder that gradually thins towards the electromagnet avoids large-area contact between the outer circumference of the heat-conducting cylinder and the inner wall of the receiving groove, which would lead to heat loss. This further improves the efficiency and accuracy of heat conduction, allowing the first temperature-controlled memory spring 34 and the second temperature-controlled memory spring 47 to quickly sense changes in the temperature inside the concha, providing timely and accurate temperature signals for subsequent electrode removal.

[0054] When the patient falls asleep, the detection component detects that the continuous heat generated by the electrodes has caused the ear temperature to reach the safe threshold (greater than 37.2℃) for detachment from the component. At this point, the force of the second temperature-controlled memory spring 47 increases, causing the second slider 39 to rise and compress the second spring 38. As the second slider 39 moves upward, it causes the sliding column 40 and the second electrode 9 to rise together. When the second electrode 9 raises its top metal plate 29 to the attraction area of ​​the second electromagnet 27, the second electromagnet 27 instantly applies an upward attractive force to the second metal plate 29, causing the second electrode 9 to rise rapidly. When the second metal plate 29 is attracted to the... When the second electromagnet 27 reaches the bottom, the conductive rod 15 will also rise into the release groove 42. Since the inner diameter of the release groove 42 is larger than the diameter of the conductive rod 15, the second electrode 9 is completely separated from the first electrode 7 and stops being energized. At this time, only the first electrode 7 continues to work, thereby greatly reducing the heat generation of the electrode as a whole, quickly relieving the temperature rise inside the patient's concha, and avoiding low-temperature burns caused by the electrode continuously heating and contacting the skin. At the same time, the single electrode low-power working mode will not interrupt the basic gentle stimulation of the vagus nerve, and can reduce the interference with the patient's deep sleep and reduce the power consumption of the entire device, taking into account both wearing safety and sleep stability.

[0055] Because patients with chronic diseases are prone to fragmented sleep during sleep, resulting in insufficient deep sleep duration and significantly reduced sleep quality, if the electrodes remain detached during this time, timely intervention is impossible, and the patient may wake up directly. When the detection component captures physiological signals of fragmented sleep such as heart rate fluctuations and increased body movement, and determines that the patient is about to transition from deep sleep to light sleep or wake up, the regulating controller 1 will immediately de-energize the second electromagnet 27. The elastic restoring force of the second spring 38 will push the second slider 39 down, causing the second electrode 9 to descend synchronously. The conductive rod 15 will then slide down into the mating groove 16, allowing the first electrode 7 and the second electrode 9 to re-contact and conduct, restoring normal electrical stimulation. This quickly intervenes in the vagus nerve, helping the patient to re-enter a stable deep sleep state, effectively improving the problem of fragmented sleep in patients with chronic diseases, and significantly improving overall sleep quality.

[0056] When the detection component detects a temperature greater than 37.9°C inside the patient's concha, the protection component immediately activates. The first temperature-controlled memory spring 34 deforms under pressure, increasing the force and causing the first slider 35 to slide upwards and compress the first spring 36. Simultaneously, the first slider 35 pulls the slider 37 and the first electrode 7 upwards. When the first electrode 7 raises the top first metal plate 28 to the attraction area of ​​the first electromagnet 26, the first electromagnet 26 instantly generates a magnetic attraction and applies an upward attraction force to the first metal plate 28, causing the first electrode 7 to quickly rise to the designated position, completely detaching the first electrode 7 from the patient's concha skin. At this point, the first electrode 7 and the first... Neither electrode 9 comes into contact with the patient's skin, cutting off all heat sources at the source and rapidly reducing the temperature inside the concha. This prevents damage such as low-temperature burns to the delicate ear canal skin of patients with chronic diseases caused by continuous temperature increases. This protective component is the last line of defense against overheating of the device. Together with the disengagement component, it forms a dual-temperature graded protection. At 37.2°C, single-electrode disengagement and heat reduction are triggered, and at 37.9°C, full-electrode forced disengagement and heat stoppage are triggered. This not only takes into account the sleep-aid intervention needs during deep sleep, but also provides a rapid and thorough protective response when overheating risks occur. It is adapted to the physical state and ear canal environment of patients with chronic diseases during sleep, greatly improving the safety and compatibility of the device.

[0057] When the patient finishes using the device, the device is turned off. At this time, both the first electromagnet 26 and the second electromagnet 27 are de-energized, and the temperature around the first temperature-controlled memory spring 34 and the second temperature-controlled memory spring 47 will drop below the threshold, thereby realizing the reset of the first electrode 7 and the second electrode 9, which is convenient for the patient to continue using the device.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
