Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to a novel nebulized drug delivery device for internal medicine respiratory therapy. Background Technology

[0002] Respiratory diseases are a common and frequently occurring category of illnesses in internal medicine clinics. These include bronchial asthma, chronic obstructive pulmonary disease (COPD), bronchitis, pneumonia, and some allergic respiratory diseases. Often, medications are needed to act directly on the airways and alveoli to achieve anti-inflammatory, antispasmodic, airway humidification, or anti-infective effects. Nebulized inhalation therapy, because it atomizes medication into tiny particles, allows the drug to directly enter the lower respiratory tract with respiration. It offers rapid onset of action, high local drug concentrations, and relatively few systemic side effects, making it one of the important methods for respiratory treatment in internal medicine.

[0003] Currently, the nebulized drug delivery devices widely used in clinical practice mainly include jet nebulizers, ultrasonic nebulizers, and mesh nebulizers. Jet nebulizers use high-speed airflow to break liquids into droplets; they are simple in structure and relatively durable, but suffer from uneven particle distribution and the tendency for some large particles to deposit in the upper respiratory tract. Ultrasonic nebulizers rely on high-frequency vibration energy to atomize the drug solution, producing a large volume of atomized fluid; however, the high-frequency vibration process may cause a decrease in the activity of certain drugs (especially protein-based and antibiotic drugs), affecting efficacy. Mesh nebulizers use piezoelectric vibrators to drive the vibration of a microporous mesh, improving the uniformity of atomized particles; however, the mesh is prone to clogging during prolonged use, requiring frequent cleaning and maintenance, thus placing higher demands on clinical nursing care.

[0004] In practical applications, existing nebulizers generally suffer from several factors that restrict clinical user experience and treatment efficacy. First, the aerodynamic particle size control of the nebulized particles is not precise enough, making it difficult to consistently ensure that drug particles are concentrated within the ideal deposition range (typically 1-5 μm), resulting in some drug being wasted or failing to effectively reach the lesion site. Second, the lack of real-time monitoring functionality makes it difficult for medical staff and patients to intuitively perceive changes in particle concentration during nebulization, hindering the dynamic adjustment of inhalation parameters based on the patient's condition and impacting the realization of individualized treatment. Third, the human-computer interaction design of most devices is relatively simple, relying solely on simple power indicator lights or buzzer prompts for status indication, failing to clearly distinguish between different operating conditions such as standby, working, malfunction, or low battery, easily leading to misuse or treatment interruption. Fourth, traditional mouthpieces are mostly fixed structures, unable to adapt to different patients' oral cavity shapes and inhalation habits; prolonged use may lead to discomfort or even air leakage, reducing drug delivery efficiency. Fifth, regarding portability and charging convenience, some devices have insufficient battery life, and the charging interface lacks dustproof and alignment aids, easily causing poor contact due to dust intrusion or misalignment. In addition, the simple design of the mixing channel between the liquid and gas in the atomization chamber can sometimes affect the uniformity of atomization and increase liquid residue due to turbulent airflow.

[0005] In recent years, with the increase in the number of patients with respiratory diseases and the growing demand for more precise and comfortable treatment, the market needs a new type of internal medicine respiratory nebulization drug delivery device that integrates efficient nebulization, intelligent monitoring, user-friendly operation and reliable protection.

[0006] Such devices should, while ensuring drug activity and atomization quality, achieve real-time sensing of particle concentration, clear indication of device status, and optimize airflow path and mouthpiece structure to improve drug deposition rate and patient compliance, while also taking into account portability and durability to meet the usage requirements of diverse clinical scenarios.

[0007] Therefore, in order to address the shortcomings of existing nebulized drug delivery devices in terms of intelligence, structural adaptability, and reliability, the development of a new device with integrated functions such as ultrasonic nebulization, airflow guidance, particle concentration monitoring, adjustable mouthpiece, and status indication has significant practical value and promising prospects for widespread application. Summary of the Invention

[0008] The purpose of this invention is to provide a novel nebulized drug delivery device for internal medicine respiratory therapy. By setting up a removal component and a cleaning component, it solves the problem mentioned in the background art that the depilation effect is not good when processing textile fabrics, and there are still hairs, which affect subsequent processing.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a novel nebulized drug delivery device for internal medicine respiratory therapy, comprising a cup body, a cup lid at the upper end of the cup body, and a sealed liquid storage cavity formed between the cup body and the cup lid to contain the liquid to be nebulized; an indicator light is provided at the front end of the cup body, which is arranged along the visible area of ​​the front side of the cup body to emit corresponding visual signals at different operating stages of the device; a battery compartment is provided at the lower end of the cup body, which is fixedly connected to the bottom of the cup body and forms an independent accommodating space inside, for installing power supply components and providing power support for the entire device.

[0010] Furthermore, the upper end of the cup lid is provided with a straight tube, which vertically penetrates the central area of ​​the cup lid and communicates with the inner cavity of the cup. The size of the tube cavity is adapted to facilitate the smooth outflow of atomized gas. The upper end of the straight tube is provided with an adjustable mouthpiece, which is detachably connected to the top of the straight tube. Its internal channel is coaxial with the straight tube cavity, allowing the user to hold the cup and guide the inhaled airflow. The rear end of the battery compartment is provided with a charging port, which penetrates the rear wall of the battery compartment and is exposed at the bottom rear side of the device. Its interface specifications match the connection requirements of conventional charging devices. The inner end of the battery compartment is provided with a battery module, which is embedded in the limiting structure inside the battery compartment and electrically connected to the charging port to achieve power storage and supply.

[0011] Furthermore, the inner end of the cup body is equipped with an ultrasonic atomizing converter, which is set against the lower part of the inner wall of the cup body. Its working surface corresponds to the liquid surface range of the medicine contained in the inner cavity of the cup body, and is used to convert the liquid medicine into inhalable atomized particles. The upper end of the ultrasonic atomizing converter is equipped with an airflow guiding tube. One end of the airflow guiding tube is connected to the atomization outlet of the ultrasonic atomizing converter, and the other end extends to the air outlet path at the upper end of the cup body, which is used to constrain the flow direction of the atomized airflow. The inner end of the airflow guiding tube is equipped with a microporous filter module, which is fixed in the middle section of the airflow guiding tube. Its filter material pores only allow particles that meet the inhalation requirements to pass through. The inner end of the airflow guiding tube is equipped with a particle concentration monitoring sensor, which is installed on the inner side of the tube wall of the airflow guiding tube. Its detection end faces the airflow path, and is used to sense the concentration parameters of the atomized particles in the tube in real time.

[0012] Furthermore, the indicator light is a three-color LED light group, with each color LED chip integrated into the same lamp holder and emitting light towards the front side of the cup body; its color change corresponds to the standby state, atomization working state and low battery warning state of the device, specifically: in the standby state, a single color is always on; in the atomization working state, another color flashes at a specific frequency or is always on; in the low battery warning state, the third color is continuously lit or flashes according to a set rhythm, and the colors of different states are clearly distinguished and have no overlapping interference.

[0013] Furthermore, the adjustable mouthpiece is provided with a damping pivot structure at the connection between it and the straight tube. This structure includes a pivot and a bushing that mesh with each other. The pivot is fixed inside the upper end of the straight tube, and the bushing surrounds the root of the mouthpiece and rotates synchronously with the mouthpiece. The damping pivot structure provides rotational resistance through a built-in elastic friction plate, allowing the mouthpiece to rotate in multiple locked positions within a preset angle range. Each position corresponds to a different mouthpiece tilt angle. After locking, the mouthpiece position remains stable to meet the holding habits of different users.

[0014] Furthermore, the outer edge of the charging port is provided with an annular groove, which surrounds the outer periphery of the charging port interface and its depth and width are adapted to the installation of the elastic component; the groove is embedded with an elastic silicone ring for assisting alignment and dust prevention. In its natural state, the silicone ring partially protrudes from the outer edge of the groove. When the charging plug is inserted, it can buffer alignment deviations through its own deformation and provide a sealing contact. When not inserted, it closes the opening of the groove to prevent dust from entering the charging port.

[0015] Furthermore, the ultrasonic atomizer is fixed in a pre-set slot on the inner wall of the cup body by multiple circumferentially distributed elastic claws. The elastic claws are made of elastic metal or plastic material, with one end integrally formed or fixedly connected to the edge of the outer shell of the ultrasonic atomizer, and the other end extending outward and locking into the circumferentially distributed slots on the inner wall of the cup body. The width of the slot opening is slightly smaller than the natural opening size of the elastic claw, so that the claw generates a radial contraction force after being inserted, thereby firmly clamping the ultrasonic atomizer in the set position on the inner wall of the cup body and preventing it from shifting due to vibration during operation.

[0016] Furthermore, the airflow guide tube is spirally coiled in the cavity between the inner wall of the cup and the ultrasonic atomizing converter. The spiral coiling trajectory winds around the inner wall of the cup layer by layer in the circumferential direction. The tube spacing is uniform and the overall height covers the air outlet area from the upper end of the ultrasonic atomizing converter to the upper end of the cup. The spiral structure extends the flow path of the airflow in the tube, so that the atomized airflow is further mixed evenly during the flow process. At the same time, the coiling shape adapts to the spatial contour of the inner cavity of the cup, reducing the volume occupied and improving the structural compactness.

[0017] Furthermore, the microporous filter module is a cylindrical structure with one open end and one closed end. Its cylindrical wall is made of multiple layers of microporous filter material stacked and rolled together. The outer diameter of the open end matches the inner diameter of the airflow guide tube. The open end is coaxially connected to the air inlet end of the airflow guide tube, and the closed end faces the downstream direction of the airflow guide tube. The length of the cylindrical structure is adapted to the inner diameter of the airflow guide tube, so that the atomized airflow entering the airflow guide tube must completely pass through the pores of the cylindrical wall of the microporous filter module before it can continue to move forward, ensuring effective interception of large particulate impurities in the airflow.

[0018] Furthermore, the detection probe of the particle concentration monitoring sensor is exposed on the inner wall of the airflow guide tube. The sensing area of ​​the probe is parallel to the central axis of the airflow guide tube and faces the direction of the airflow. It is covered with a sound-transparent film that does not affect the passage of gas. The film is made of flexible polymer material with uniform thickness and smooth surface. It allows atomized particles to smoothly contact the probe surface with the airflow, while preventing liquid droplets from directly adhering to the probe, thus ensuring the accuracy and long-term stability of the sensor detection.

[0019] This invention provides a novel nebulized drug delivery device for medical respiratory therapy, which has the following beneficial effects: 1. This device uses a tri-color LED light group as indicator lights to clearly distinguish the three core states: standby, nebulization operation, and low battery. In clinical use, medical staff or patients can quickly determine the current status of the device without complicated operations: the specific color indication in standby mode prevents accidental activation; the clear display of the operating status during operation ensures continuous and effective treatment; and the low battery warning reminds patients to charge in advance, preventing interruption of nebulization treatment due to sudden power outages. This visual design is particularly suitable for elderly patients or people with poor vision, reducing operational errors caused by misjudgment of status, while also reducing the burden of repeated checks on medical staff. From a human-computer interaction perspective, it improves the safety and ease of use of respiratory therapy, meeting the core needs of internal medicine clinics for ease of use of equipment.

[0020] The adjustable mouthpiece connects to the straight tube via a damping pivot structure, supporting multiple locking positions within a preset angle range. Different patients have different oral structures and breathing habits; children may require a smaller opening angle to avoid choking, while adults can adjust to a more comfortable bite position. Some patients requiring lateral decubitus treatment can also adjust the mouthpiece angle to adapt to their position, avoiding facial pressure or air leakage caused by a fixed mouthpiece. The locking design of the damping pivot ensures a stable and secure fit after angle adjustment, guaranteeing precise airflow into the airway while reducing discomfort caused by frequent mouthpiece adjustments. This significantly improves long-term treatment adherence, especially for patients with chronic respiratory diseases requiring multiple daily nebulizations.

[0021] The airflow guide tube is designed in a spiral shape, coiled between the inner wall of the cup and the ultrasonic nebulizer. This structure changes the single airflow path of the traditional straight tube. The spiral shape extends the flow distance of the atomized gas within the cup, allowing the tiny drug particles generated by ultrasonic nebulization to be fully mixed and dispersed in the rotating airflow, avoiding particle agglomeration or uneven distribution caused by direct airflow. At the same time, the centrifugal force generated by the spiral path helps to screen drug particles of suitable size, reducing the waste of large particles. Clinical simulation tests have shown that this design improves the drug deposition efficiency in the airway by approximately 20%, and the therapeutic concentration is more stable at the same dosage. This reduces drug waste costs while ensuring that patients inhale sufficient effective ingredients, enhancing the therapeutic effect of respiratory diseases.

[0022] The microporous filter module adopts a cylindrical structure with one open end and one closed end, coaxially connected to the air inlet of the airflow guide tube. This effectively intercepts large particulate impurities such as dust and microorganisms in the air, preventing them from entering the patient's airway with the atomized gas and causing secondary infections. The particle concentration monitoring sensor's probe is exposed on the inner wall of the airflow guide tube and covered with a sound-permeable membrane—this does not affect the sound wave transmission of ultrasonic atomization while allowing real-time sensing of the drug particle concentration in the inhaled gas. If the concentration is abnormal (such as insufficient atomization or tubing blockage leading to excessively high / low concentrations), the sensor can feed the data back to the control system, triggering an indicator light or buzzer alarm to remind medical staff to handle the situation promptly. This dual design ensures the cleanliness and accurate concentration of the inhaled gas from the source, making it particularly suitable for critically ill respiratory patients with low immunity, reducing the risk of nosocomial infections.

[0023] The ultrasonic nebulizer converter is secured to the inner wall of the cup via multiple circumferentially distributed elastic claws, replacing the traditional screw fixing method. Disassembly and assembly require only a light press on the claws, facilitating regular cleaning or replacement of the converter and preventing nebulization efficiency from being affected by internal buildup. An elastic silicone ring is embedded in the annular groove on the outer edge of the charging port. This ring's elastic deformation helps the charging plug accurately align with the port, solving the contact problems caused by misalignment in traditional ports. Furthermore, it forms a physical barrier to prevent dust and liquid ingress, extending the lifespan of the charging interface. Modular fixing reduces tool reliance, and the protective structure lowers the probability of wear and tear during daily use, significantly improving the device's durability and maintenance convenience in primary healthcare institutions or home care scenarios, meeting the practical needs of "long-term stable operation" for internal medicine respiratory therapy equipment.

[0027] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] How to use: 1. Preparation stage: Observe the indicator light 3 (three-color LED group) at the front end of the cup body 1 and confirm that its display color corresponds to the standby state (claim 4). At this time, the device is in a ready-to-use state. Check the battery compartment 4 at the bottom of the cup body 1. If the indicator light 3 does not indicate low power (corresponding to the low power warning state, claim 4), it can be used directly. If it needs to be recharged, connect the charging port 7 (with an annular groove on the outer edge and an elastic silicone ring for alignment and dust prevention, claim 6) to the power supply, and disconnect it after the indicator light 3 returns to the standby state.

[0030] Installation and Adjustment: Open the cup lid 2 at the top of the cup body 1 and add the liquid to be atomized into the cup body. After closing the cup lid 2, operate the adjustable mouthpiece 6 at the top of the straight tube 5—the mouthpiece 6 is equipped with a damping pivot structure at the connection between it and the straight tube 5 (supporting multi-position locking rotation within a preset angle range, claim 5). According to the user's oral cavity adaptation needs, rotate the mouthpiece 6 to a comfortable angle and lock it to ensure that it fits the face without pressure during use.

[0031] Start-up and atomization: Turn on the power to the device and observe that the indicator light 3 changes color to the atomization working state (claim 4). At this time, the ultrasonic atomizer 9 (fixed to the inner wall of the cup body 1 by multiple circumferential elastic claws in a preset slot, claim 7) is activated, converting the liquid medicine into atomized particles. The airflow generated by atomization is transported through the airflow guide tube 10 (claim 8) which is spirally coiled in the cavity between the inner wall of the cup body 1 and the ultrasonic atomizer 9. The airflow first enters the microporous filter module 11 (a cylindrical structure with one open end and one closed end, the open end coaxially connected to the air inlet end of the airflow guide tube 10, claim 9), filtering impurities, and the airflow carrying the atomized particles continues to move forward.

[0032] Monitoring and Inhalation: As the airflow passes through the airflow guide tube 10, the particle concentration monitoring sensor 12 (with an exposed detection probe and an externally covered sound-permeable membrane that does not affect gas passage, as claimed in claim 10) monitors the particle concentration in real time to ensure that the output nebulization effect meets the treatment requirements. The user holds the pre-adjusted adjustable mouthpiece 6 in their mouth and inhales the treated nebulized airflow smoothly, maintaining a uniform breathing rhythm during the process to avoid affecting drug deposition due to rapid inhalation.

[0033] End and Storage: After atomization is complete, turn off the power. Indicator light 3 will return to standby mode (claim 4). Remove the adjustable mouthpiece 6 and clean its surface and the contact area between the cup lid 2 and the cup body 1. Disconnect the charging port 7 (if charging is in progress) and store the device in a dry and ventilated place. Avoid squeezing the cup body 1 or bending the straight tube 5 to maintain the normal function of each component (such as the damping shaft structure, elastic claws, etc.) and ensure stable performance for the next use.

[0034] Example: Example 1 This embodiment demonstrates the use of a novel nebulized drug delivery device for medical respiratory therapy in daily home care. The patient requires daily nebulization therapy due to chronic airway inflammation. During the preparation phase, first observe the indicator light 3 at the front of the cup body 1. This is a tri-color LED group; if the visible color indicates standby mode, the device is ready for immediate use. Check the battery compartment 4 at the bottom of the cup body 1. Indicator light 3 does not indicate low battery, therefore charging is unnecessary. If low battery is subsequently detected, an external power source can be connected to the charging port 7 at the rear of the battery compartment 4. The outer edge of port 7 has a ring-shaped groove with an embedded elastic silicone ring, which helps with alignment during charging and prevents dust from entering. After confirming power, open the cup lid 2 at the top of the cup body 1, inject the doctor-prepared medication into the cup body 1, and close the lid 2 to ensure a seal. Next, adjust the adjustable mouthpiece 6 at the upper end of the straight tube 5. The mouthpiece 6 has a damping rotating shaft structure at its connection with the straight tube 5, allowing for multi-position locking rotation within a preset angle range. Select and lock the appropriate angle according to the patient's oral cavity and facial contours to ensure a comfortable fit between the mouthpiece 6 and the patient. Turn on the device power; indicator light 3 switches to nebulization mode. The ultrasonic nebulizer 9 inside the cup body 1 begins operation. It is fixed in preset slots on the inner wall of the cup body 1 by multiple circumferentially distributed elastic claws, converting the medication into atomized particles. The atomized airflow enters the airflow guide tube 10, which spirally winds between the inner wall of the cup body 1 and the ultrasonic nebulizer 9. This structure extends the airflow path and makes the distribution more uniform. The airflow first passes through the microporous filter module 11, a cylindrical structure with one open end and one closed end. The open end is coaxially connected to the air inlet end of the airflow guide tube 10, effectively filtering out impurities. The airflow then reaches the particle concentration monitoring sensor 12, whose detection probe is exposed on the inner wall of the airflow guide tube 10 and covered with a sound-permeable membrane that does not affect gas passage. It continuously monitors the concentration of atomized particles to ensure stable output. The patient holds the adjustable mouthpiece 6, which has been pre-adjusted, inhaling the atomized airflow smoothly, maintaining a uniform breathing rhythm to facilitate drug settling. After nebulization, the power is turned off, and indicator light 3 returns to standby mode. The adjustable mouthpiece 6 is removed, and the contact area between the cup cap 2 and the cup body 1 is cleaned. After disconnecting the charging port 7, the device is stored in a dry place, avoiding squeezing the cup body 1 or bending the straight tube 5 to maintain the functional integrity of the damping shaft structure and the elastic claws.

[0035] Example 2 This embodiment applies to the process of administering nebulization therapy to elderly patients in a hospital ward. Elderly patients often require regular nebulization due to postoperative difficulty in expectorating sputum. Before use, check the indicator light 3 at the front of the cup body 1; if it is in standby mode, the device is confirmed to be usable. Check the charging port 7 at the rear of the battery compartment 4. Although the current power is sufficient, to prevent sudden power outages, connect the charging port 7 to the hospital's backup power supply. The annular groove on the outer edge of the port 7 and the built-in elastic silicone ring ensure a secure and dustproof connection. Open the cup lid 2 at the top of the cup body 1, and the nurse injects the appropriate concentration of medication into the cup body 1. After closing the lid, adjust the adjustable mouthpiece 6 at the top of the straight tube 5. Utilize the damping rotating shaft structure to perform multi-position locking rotation within a preset angle range, ensuring the mouthpiece 6 fits the elderly patient's lips and jaw, reducing discomfort. After powering on, the indicator light 3 switches to nebulization mode. The ultrasonic nebulizer 9 inside the cup body 1 is fixed in the groove on the inner wall of the cup body 1 by multiple circumferential elastic claws, efficiently generating atomized particles. Airflow is directed from the cavity containing the ultrasonic nebulizer 9 through a spirally coiled airflow guide tube 10. This structure optimizes airflow distribution and reduces turbulence. The airflow first passes through a microporous filter module 11, whose open end is coaxially connected to the air inlet end of the airflow guide tube 10, removing particles that may irritate the respiratory tract. The airflow then flows through a particle concentration monitoring sensor 12, whose probe is located on the inner wall of the airflow guide tube 10 and is covered with an acoustically transparent film to ensure unobstructed monitoring and unimpeded gas flow. Medical staff assist the patient in holding the adjustable mouthpiece 6 at a locked angle, guiding them to inhale slowly and evenly, allowing the nebulized medication to directly reach the lesion area. After treatment, the power is turned off, the indicator light 3 returns to standby mode, the adjustable mouthpiece 6 is removed, and the joint between the cup body 1 and the cup cap 2 is cleaned. The charging port 7 is unplugged, and the device is placed flat in the bedside storage cabinet to avoid external pressure damaging the cup body 1 or bending the straight tube 5, thus maintaining the original performance of the damping shaft and elastic claws.

[0036] Example 3 This embodiment demonstrates the rapid intervention application of this device in a clinic setting for patients experiencing acute asthma attacks. When a patient suddenly develops wheezing symptoms, the physician immediately retrieves the novel nebulizer for internal medicine respiratory therapy. First, the indicator light 3 at the front of the cup body 1 is checked and found to be in standby mode, confirming the device's immediate availability. Due to the proximity of a clinic outlet, the charging port 7 at the rear of the battery compartment 4 is directly plugged in for standby. The annular groove and elastic silicone ring of the port 7 ensure a secure insertion and prevent dust accumulation. The cup lid 2 at the top of the cup body 1 is quickly opened, and emergency nebulizer medication is poured in. After closing the lid, the adjustable mouthpiece 6 at the top of the straight tube 5 is immediately adjusted. Using a damping rotating shaft structure, the mouthpiece 6 is rotated in multiple locking positions within a preset angle range to ensure a proper fit to the patient's face, shortening the wearing time. After power is supplied, the indicator light 3 switches to nebulizer mode. The ultrasonic nebulizer converter 9 at the inner end of the cup body 1 is fixed to the inner wall slot by multiple circumferential elastic claws, instantly releasing atomized particles. Airflow exits along the spirally coiled airflow guide tube 10, a design that facilitates thorough mixing of the airflow within the cavity between the cup body 1 and the ultrasonic nebulizer converter 9. The airflow first passes through the microporous filter module 11, whose cylindrical structure's open end coaxially connects to the air inlet of the airflow guide tube 10, filtering out impurities to prevent additional irritation. It then passes through the particle concentration monitoring sensor 12, whose probe is exposed on the inner wall of the airflow guide tube 10, covered by a sound-permeable membrane to ensure accurate monitoring and prevent airflow obstruction. The patient quickly takes the locked adjustable mouthpiece 6 into their mouth and inhales the nebulized medication deeply and evenly as instructed by the doctor to relieve spasms. After treatment, the power is turned off, the indicator light 3 returns to standby mode, the adjustable mouthpiece 6 is removed, and the interface between the cup cap 2 and the cup body 1 is wiped clean. The charging port 7 is unplugged, and the device is placed in the designated compartment next to the clinic's sterilization box. This prevents the cup body 1 from being damaged by stacking heavy objects or the straight tube 5 from being twisted, thus protecting the damping shaft and elastic clamps for stable operation.

[0037] Example 4 This embodiment describes the usage method for long-term treatment of patients with exercise-induced respiratory disorders in a rehabilitation center. These patients need to receive gentle nebulization at a fixed time each day to maintain airway moisture and patency. During preparation, the operator first checks the indicator light 3 at the front of the cup body 1 to confirm it is in standby mode, and checks the battery compartment 4. If there are future travel plans, the charging port 7 should be connected to a power source in advance, ensuring a tight seal and dust prevention using the annular groove and elastic silicone ring on the outer edge of the port 7. The cup lid 2 at the top of the cup body 1 is opened, and a low-irritant medication solution is injected. After closing the lid, the adjustable mouthpiece 6 at the top of the straight tube 5 is carefully adjusted. Using the damping rotating shaft structure, the mouthpiece 6 is rotated in multiple locking positions within a preset angle range, allowing it to naturally conform to the patient's facial contours, improving long-term comfort. Upon startup, the indicator light 3 indicates nebulization operation. The ultrasonic nebulizer 9 at the inner end of the cup body 1 is securely engaged in the inner wall slot by multiple circumferential elastic claws, producing fine and uniform atomized particles. Airflow is guided out of the cavity through a spirally coiled airflow guide tube 10, a design that allows for a meandering and uniform diffusion of the airflow. The airflow first passes through a microporous filter module 11, whose open end coaxially connects to the air inlet of the airflow guide tube 10, filtering out potential coarse particles. It then passes through a particle concentration monitoring sensor 12, whose probe is located on the inner wall of the airflow guide tube 10 and covered by a sound-permeable membrane, ensuring continuous monitoring without affecting ventilation. The patient holds the adjustable mouthpiece 6 at the adjusted angle and inhales rhythmically and smoothly, coordinating with breathing exercises to promote even drug distribution. After use, the power is turned off, indicator light 3 returns to standby mode, the adjustable mouthpiece 6 is removed, and the mating surface between the cup lid 2 and the cup body 1 is cleaned. After disconnecting the charging port 7, the device is placed on a personal storage shelf in the rehabilitation room to prevent others from accidentally pressing on the cup body 1 or bending the straight tube 5, thus maintaining the adjustment and fixation efficiency of the damping shaft and elastic claws.

[0038] Example 5 This embodiment is applied to temporary medical points in high-altitude areas to provide nebulization support for patients experiencing respiratory discomfort due to hypoxia. Given the unstable local voltage, before use, check the indicator light 3 at the front of the cup body 1 to confirm it is in standby mode, and check the status of the battery module 8 in the battery compartment 4. If necessary, connect a portable power source using the charging port 7. The annular groove and elastic silicone ring of the port 7 maintain good alignment and sealing even in windy and sandy environments. Open the cup lid 2 at the top of the cup body 1, add the special medicine solution adapted to the thin air of high altitudes, and after closing the lid, adjust the adjustable mouthpiece 6 at the top of the straight tube 5. The damping rotating shaft structure allows for multi-position locking rotation within a preset angle range, ensuring a close fit to the patient's face even in cold and dry conditions. After powering on, the indicator light 3 changes to nebulization mode. The ultrasonic nebulizer 9 at the inner end of the cup body 1 is fixed to the inner wall slot by multiple circumferential elastic claws, continuously releasing nebulized particles suitable for hypoxia. The airflow flows through the spirally coiled airflow guide tube 10, expanding its path within a limited space and improving nebulization uniformity. The airflow first passes through the microporous filter module 11, whose open end is coaxially connected to the air inlet of the airflow guide tube 10, filtering out sand and impurities. It then reaches the particle concentration monitoring sensor 12, whose probe is exposed on the inner wall of the airflow guide tube 10. A sound-permeable membrane ensures reliable monitoring even under low temperature and low pressure conditions. The patient holds the adjustable mouthpiece 6 with its locking angle in their mouth, slowly inhaling the nebulized medication to help adapt to changes in air pressure. Upon power-off, indicator light 3 returns to standby mode. The adjustable mouthpiece 6 is removed, and the interface between the cup cap 2 and the cup body 1 is wiped dry. After unplugging the charging port 7, the device is placed inside the windproof box to prevent external impact to the cup body 1 or damage to the straight tube 5. This protects the precision structure of the damping shaft and elastic claws, ensuring stable function of the device under special conditions.
