Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a temperature-controlled walnut moxibustion device for relieving dry eye symptoms. Background Technology

[0002] Sjögren's syndrome is a chronic autoimmune disease characterized by decreased secretion from the lacrimal and salivary glands. In traditional Chinese medicine, it is often diagnosed as "dryness-related arthralgia" or "yin deficiency and fluid depletion." In recent years, there have been clinical attempts to use moxibustion to improve microcirculation and promote glandular secretion, but due to the thin and delicate skin around the eyes, traditional moxibustion with moxa sticks or ginger-separated moxibustion is difficult to apply.

[0003] Walnut moxibustion, a unique therapy combining the penetration of traditional Chinese medicine with the heat effect of moxibustion, possesses unique clinical value in the prevention and treatment of eye diseases. Existing walnut moxibustion devices are typically designed with an eyeglass frame structure to enhance patient convenience and comfort. In practical applications, controlling the axial distance between the moxa stick and the walnut shell carrying the medicinal liquid is the most direct and common technique for adjusting the treatment temperature. Shortening the heat source distance manually or through simple mechanical structures can enhance the intensity of heat received by the eyes.

[0004] The study found that the diffusion dynamics of the drug within the porous biomass medium of walnut shells have a strong nonlinear coupling relationship with heat flux. That is, the saturated vapor pressure of the liquid increases exponentially with increasing temperature. This means that when users reduce the spacing between moxa sticks to obtain a higher treatment temperature, the concentration of the drug inside the walnut shell will increase due to the increased heat energy.

[0005] Although existing technologies attempt to adjust temperature by changing the distance to the heat source, the combination of the roughness of manual operation and the lag due to thermal inertia during manual adjustment often results in the concentration of medicinal gas at the opening of the walnut shell approaching or even exceeding the physiological tolerance threshold of the ocular mucosa at the beginning of adjustment. The resulting chemical stimulation not only reduces treatment compliance but also leads to excessive consumption of the active ingredients in the early stages of treatment. Due to the lack of active intervention methods for the diffusion cross-sectional area, the drug output of existing devices exhibits drastic fluctuations under different heat intensities, making it difficult to maintain a stable thermo-pharmaceutical synergy during long-term treatments. Ultimately, this leads to a shortened effective duration of a single treatment and poses a risk of eye burns due to improper adjustment. Summary of the Invention

[0006] The purpose of this invention is to provide a temperature-controlled walnut moxibustion device for relieving dry eye symptoms, thereby solving the technical problems of imbalanced heat release and waste caused by high concentration release of medicine due to the single adjustment of the heat source distance in the prior art.

[0007] The technical solution of the present invention is as follows:

[0008] A temperature-controlled walnut moxibustion device for relieving dry eye symptoms includes a frame, a walnut moxibustion component installed at the front of the frame, and a moxa cone carrier movably connected to the front of the frame and arranged on the front side of the walnut moxibustion component.

[0009] The walnut moxibustion component includes a medicinal carrier, which is a walnut shell or a walnut shell-like structure. The medicinal carrier has a rear end opening facing the human eye, and a flow regulation mechanism is provided at the rear end opening.

[0010] The flow regulation mechanism includes at least two blades that block the rear opening, and an aperture connecting the rear opening and the human eye is provided between each blade. It also includes a drive component that drives each blade to adjust the aperture.

[0011] The frame is also equipped with a linkage actuator that is connected to the drive component and the moxibustion column carrier.

[0012] When the moxa cone carrier moves backward toward the pharmacological carrier, the linkage actuator drives the blade to reduce the opening of the pore; and when the moxa cone carrier moves forward away from the pharmacological carrier, it drives the blade to expand the opening of the pore.

[0013] Furthermore, the flow regulation mechanism is an iris-type throttling structure, including a rotating adjustment ring. There are several blades that are arranged in an overlapping manner to form the orifice at the center, and the blades are driven by the adjustment ring to make centripetal or centrifugal movements to adjust the orifice size.

[0014] Furthermore, the outer circumferential surface of the adjustment ring is provided with a toothed structure, the frame is rotatably provided with a transmission sleeve, the outer side of the transmission sleeve is provided with driving teeth that mesh with the toothed structure, the inner wall of the transmission sleeve is provided with a driving protrusion, and the linkage actuator includes a linkage push rod that moves synchronously with the moxibustion column carrier. The circumferential surface of the linkage push rod is provided with a spiral guide groove for the driving protrusion to be embedded, so that when the linkage push rod moves back and forth, it forces the transmission sleeve to rotate and drives the adjustment ring to reciprocate.

[0015] Furthermore, the frame is also equipped with a driver that drives the moxibustion column carrier to reciprocate. The driver includes a micro stepper motor and a lead screw driven by the micro stepper motor. The moxibustion column carrier includes a base with an internal thread mounted on the lead screw. The linkage push rod is fixedly connected to the base.

[0016] Furthermore, the rear side of the eyeglass frame is provided with a temperature sensor for detecting the temperature near the human eye. The eyeglass frame is also provided with a controller, which is connected to the temperature sensor and the driver signal, so that when the temperature sensor detects that the temperature exceeds the threshold at both ends of the range, the driver is controlled to move the moxibustion column carrier back and forth.

[0017] Furthermore, both ends of the frame have L-shaped plate segments that are integrally formed with the frame, the lead screw is rotatably mounted on the L-shaped plate segment, and the side wall of the L-shaped plate segment has a guide groove that extends forward and backward, and the base of the moxibustion carrier is slidably mounted in the guide groove.

[0018] Furthermore, the frame includes a frame base and temples symmetrically arranged on both sides of the frame base. The driver is symmetrically arranged inside the front end of the temple. The frame base has a receiving hole, and the transmission sleeve is rotatably assembled in the receiving hole.

[0019] Furthermore, there are two or more drive protrusions, which are evenly distributed around the circumference of the transmission sleeve.

[0020] Furthermore, the walnut moxibustion assembly also includes a clamp assembly that is movably mounted on the frame. The clamp assembly includes two clamp plates arranged opposite each other. The opposite sidewalls of the clamp plates are provided with locking grooves for fitting onto the outer rear end of the medicinal carrier. The two clamp plates are driven by an elastic element and tend to move closer to each other.

[0021] Furthermore, the hoop plate is an arc-shaped plate, and a guide rod is connected to the middle position of the arc-shaped plate. The frame is provided with a guide hole for the guide rod to pass through. The elastic element is a compression spring sleeved on the guide rod and mounted on the hoop plate and the frame.

[0022] The beneficial effects of this application are as follows: Compared with the prior art, the temperature-controlled walnut moxibustion device for relieving dry eye symptoms involved in this invention innovatively seals the flow regulation mechanism directly at the rear opening of the medicine carrier, which can directly implement precise intervention at the last gate of the medicine gas entering the human eye interface, ensuring a high degree of consistency between the regulation site and the treatment target, and effectively reducing the loss caused by the disorderly dispersion of medicine gas inside the cavity.

[0023] Furthermore, as the moxa cone carrier moves backward to approach the drug carrier for temperature regulation, the linkage actuator synchronously drives at least two blades to close towards the center to reduce the pore size. This action utilizes the real-time increase in cross-sectional resistance to offset the increase in the drug volatilization rate induced by the surge in heat flux. This synergistic effect of decreasing temperature rise results in a linear and stable drug release concentration.

[0024] Meanwhile, because the pore opening automatically narrows with increasing heat source intensity, patients with dry eye syndrome will not experience the impact of high-concentration medicinal gas on their ocular mucosa when the treatment temperature is increased. This keeps the perceived irritation within the physiological tolerance threshold, significantly improving the safety and comfort of the treatment process. Furthermore, by inhibiting excessive release during the high-temperature period, this application effectively prolongs the effective duration of a single application of the medicinal solution, avoiding unnecessary waste of the medication in the early stages of treatment. It fundamentally solves the technical challenge of heat-medicine imbalance during walnut moxibustion treatment, providing a more stable and efficient technical means to alleviate dry eye symptoms.

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0041] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0042] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0043] A specific embodiment of the temperature-controlled walnut moxibustion device for relieving dry eye symptoms of the present invention: The walnut moxibustion device uses a precision mechanical linkage mechanism to adjust the distance of the heat source while simultaneously interfering with the diffusion interface of the medicinal gas, so as to solve the technical problems of eye mucosal irritation and low drug utilization rate caused by the imbalance of heat drug release.

[0044] like Figures 1 to 7As shown, the temperature-controlled walnut moxibustion device in this embodiment mainly includes a frame 1, a walnut moxibustion component installed at the front end of the frame 1, and a moxa cone carrier 3 movably connected to the front of the frame 1 and arranged on the front side of the walnut moxibustion component. The frame 1, as the basic carrier of the overall structure, not only supports the spatial layout and installation of the walnut moxibustion component but also provides a stable assembly foundation for the linkage actuator. The walnut moxibustion component, as the loading and volatilization unit of the medicine, has a core component called the medicine carrier 6. In a preferred embodiment, the medicine carrier 6 uses a natural walnut shell or a walnut shell-like structure with a similar porous structure. This type of structure utilizes its unique biomass fiber micropores to achieve capillary adsorption of the medicine and passive diffusion after heating.

[0045] In this embodiment, the drug carrier 6 has a rear opening 61 facing the human eye. This rear opening 61 constitutes the only physical channel for the drug gas to enter the treatment area of ​​the human eye. To achieve precise control of the drug gas release, a flow regulating mechanism is sealed at the rear opening 61. This flow regulating mechanism includes at least two cooperating blades 64. The blades 64 are overlapped or staggered to form a gap 65 connecting the rear opening 61 and the human eye in the center or edge area. By adjusting the relative position between the blades 64, the effective cross-sectional area of ​​the drug gas can be directly changed.

[0046] Furthermore, in order to drive each blade 64 to produce a coordinated effect, the flow regulation mechanism also includes a drive component that is in transmission cooperation with each blade 64. Correspondingly, a linkage actuator is provided on the frame 1 that is in transmission connection with the drive component and the moxibustion carrier 3. During the heating adjustment process, the moxibustion carrier 3 needs to move back and forth in the front and back directions. The role of the linkage actuator is to capture this linear displacement signal and convert it into the power to drive the flow regulation mechanism to produce corresponding deformation or displacement.

[0047] Specifically, when the moxa cone carrier 3 moves backward in a controlled manner to approach the drug carrier 6, the heat intensity of the drug carrier 6 increases. Due to the physical law that the saturated vapor pressure of the internal liquid increases exponentially with increasing temperature, its evaporation rate shows a dramatic increase. At this time, the linkage actuator synchronously drives the blade 64 to reduce the opening of the orifice 65, thereby increasing fluid resistance to offset the increase in the evaporation rate of the drug gas induced by the temperature rise, ensuring that the concentration of drug gas entering the human eye area is maintained within the preset safe threshold. Conversely, when the moxa cone carrier 3 moves forward away from the drug carrier 6, although the thermal driving force weakens and the evaporation rate decreases, the linkage actuator synchronously drives the blade 64 to expand the opening of the orifice 65, using the cross-sectional area compensation effect to maintain a steady-state output of drug gas concentration. This negative feedback regulation mechanism of temperature rise and decrease, and temperature decrease and increase compensation, achieves a dynamic steady-state balance between thermal intensity and drug release, fundamentally overcoming the technical problem of treatment discomfort caused by positive feedback of heat and drug.

[0048] In a preferred embodiment, the flow regulation mechanism is specifically selected as an iris-type throttling structure, which references the aperture adjustment principle of precision optical instruments. It includes a fixed ring 63 fixed inside the rear end of the frame 1, and an adjusting ring 62 rotatably mounted inside the frame 1. The adjusting ring 62 and the fixed ring 63 are coaxially arranged, and several overlapping blades 64 are connected between them. Each blade 64 is circumferentially hinged to the rear sidewall of the fixed ring 63 and slidably mounted in the guide grooves of the adjusting ring 62 via limiting pins. Each blade 64 forms the aperture 65 in the central region and moves synchronously under the centripetal or centrifugal driving force when the adjusting ring 62 rotates. Compared to a simple translational blocking structure, this iris-type throttling structure ensures that the aperture 65 is always located on the central axis of the drug carrier 6, guaranteeing the spatial symmetry of drug gas release. This results in a more uniform pressure on different areas of the eyeball, avoiding localized irritation to the cornea caused by excessively high local concentrations. Of course, in other embodiments, the flow regulation structure can also be designed as a louvered shielding structure consisting of two sliding plates with complementary orifices.

[0049] To achieve precise conversion from linear displacement to rotational motion, in this embodiment, the outer circumferential surface of the aforementioned adjusting ring 62 is provided with a toothed structure 66. A transmission sleeve 5 is rotatably mounted on the frame 1, with its axis extending forward and backward and arranged on one side of the adjusting ring 62. The outer circumferential surface of the transmission sleeve 5 is provided with driving teeth 52 that mesh with the toothed structure 66, and the inner sidewall of the transmission sleeve 5 is provided with a driving protrusion 51. The aforementioned linkage actuator includes a linkage push rod 4 that moves synchronously with the moxibustion column carrier 3. The circumferential surface of the linkage push rod 4 is provided with a spiral guide groove 41 for the driving protrusion 51 to be embedded. When the linkage push rod 4 moves forward and backward under the drive of the moxibustion column carrier 3, the spiral guide groove 41 compresses the driving protrusion 51 through the inclined surface, forcing the transmission sleeve 5 to rotate within the receiving hole 15. The rotation of the transmission sleeve 5 is transmitted to the adjusting ring 62 through the driving teeth 52, thereby realizing the opening and closing adjustment of the blade 64.

[0050] For the installation of the transmission sleeve 5, a through-hole 15 can be designed on the frame 1. The side wall of the through-hole 15 is connected to the mounting cavity of the adjusting ring 62. Then, the transmission sleeve 5 is inserted into the through-hole 15, and the frame 1 is connected to the outside through a fixed plug to limit the axial position of the transmission sleeve 5.

[0051] Since the lead of the spiral guide groove 41 can be non-linearly designed according to the volatilization characteristic curve of the liquid medicine with temperature change, non-linear control of small displacement, fast adjustment or large displacement, slow adjustment can be achieved by adjusting the helix angle of the spiral guide groove 41. In addition, the drive protrusion 51 adopts a design of two or more evenly distributed around the circumference of the transmission sleeve 5, which greatly improves the mechanical stability during the transmission process, effectively avoids the risk of jamming caused by unilateral force, and ensures the reliability of the eyeglass frame under routine adjustment. Of course, in other embodiments, the spiral guide groove 41 can also be designed to be set on the inner wall of the transmission sleeve 5, and the drive protrusion 51 can be designed on the circumferential surface of the linkage push rod 4 instead.

[0052] Additionally, the frame 1 is equipped with a driver 2 that drives the moxibustion carrier 3 to reciprocate. The driver 2 includes a micro stepper motor 21 and a lead screw 22. The moxibustion carrier 3 includes a base 31 with an internal thread 32 that mates with the lead screw 22. A linkage push rod 4 is fixedly connected to the base 31. The displacement of the moxibustion carrier 3 is precisely controlled by the stepping pulses of the micro stepper motor 21.

[0053] A temperature sensor is installed on the rear side of the frame 1, and a controller is also installed on the frame 1. The controller is connected to the temperature sensor and the driver 2. When the temperature sensor detects that the temperature exceeds the high-end threshold of the preset range, the controller sends a signal to drive the micro stepper motor 21, causing the moxa stick carrier 3 to move forward to reduce heat. At the same time, the linkage mechanism automatically expands the pore 65 to compensate for the concentration loss after the temperature drop. When the temperature is below the low-end threshold, the driver 2 drives the moxa stick carrier 3 to move backward and closer to the drug carrier 6, enhancing the volatilization of the drug through thermal radiation. At the same time, the linkage mechanism works together to narrow the pore 65. This system based on electronic fine-tuning and mechanical linkage not only reduces the user's operational burden, but also overcomes the malfunctions caused by manual adjustment by utilizing the logical consistency of the electronic control system. Of course, in other embodiments, the driver 2 can also be designed as a micro linear motor or a piezoelectric ceramic drive motor.

[0054] Furthermore, in this embodiment, the frame includes a frame base 11 and temples 12 symmetrically arranged on both sides of the frame base 11. L-shaped plate segments 13, integrally formed with the frame base 11, extend forward from both ends of the frame base 11. A lead screw 22 is rotatably mounted on the L-shaped plate segment 13. Correspondingly, a guide groove 14 extending forward and backward is provided on the side wall of the L-shaped plate segment 13. The base 31 of the eyeglass support 3 achieves precise guiding assembly through the guide groove 14, effectively ensuring the compactness of the structure and improving the coaxiality of the lead screw 22. In addition, the driver 2 is symmetrically arranged inside the front end of the temple 12 and simultaneously integrates a controller and a drive power supply, effectively utilizing the cavity of the temple 12 and balancing the overall weight of the glasses. Of course, the guide groove 14 can also be designed as a double-rail guiding mechanism.

[0055] Due to the highly random and irregular shape and size of natural walnut shells, traditional rigid fixing methods are prone to damage or poor sealing, and cannot adapt to different installation requirements. In this embodiment, a clamp assembly is designed at the front end of the frame 1. This clamp assembly includes two arc-shaped clamp plates 7 arranged opposite each other, with locking grooves 71 on their opposite sidewalls for fitting onto the outer edge of the rear end of the drug carrier 6. The two clamp plates 7 slide with the guide holes 16 on the frame 1 via guide rods 72 and are driven by compression springs fitted on the guide rods 72. This floating clamping structure, driven by elastic element 73, can automatically compensate for the shape tolerance of natural walnut shells, ensuring that the drug carrier 6 is stably and sealed at the rear opening 61, effectively preventing leakage of drug gas from unspecified gaps. This not only reduces the precision requirements for walnut shell sorting during production but also ensures the convenience for end users when replacing walnut shell consumables. In other embodiments, the clamp assembly can also be designed as a flexible metal band fastening structure with a ratchet locking mechanism.

[0056] In addition, consistent with existing technology, a protective cover (not shown in the figure) can be integrally installed on the front side of the eyeglass frame 1 to prevent smoke from flying around and to prevent excessive loss of the fumigation temperature of the moxa stick. A smoke vent is provided on the protective cover to facilitate the exhaust of smoke generated during the burning of the moxa stick.

The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
