Description

Technical Field

[0001] This invention relates to the field of nebulizer control technology, and in particular to a children's intelligent nebulizer and control system that can quantify and guide breathing patterns. Background Technology

[0002] Nebulization therapy, an important treatment for respiratory diseases, involves using a nebulizer to convert liquid medication into aerosol particles, which are then inhaled and deposited directly into the respiratory tract and lungs. Based on different nebulization principles, commonly used nebulizers in clinical practice mainly include three types: jet nebulizers, ultrasonic nebulizers, and vibrating sieve nebulizers. The effective atomized particle diameter is in the range of 0.5-10 μm, with 3.0-5.0 μm being optimal. Particles within this size range can avoid upper respiratory tract obstruction and precisely deposit in the bronchi and alveoli. Clinical studies have shown that the lung deposition rate of particles in this range can reach over 60%, making it an ideal choice for treating lower respiratory tract diseases. Compared with oral, intramuscular, and intravenous administration, nebulized inhalation therapy has advantages such as direct drug action on target organs, rapid onset of action, good efficacy, and fewer systemic adverse reactions, and is widely used in the treatment of pediatric respiratory diseases such as asthma, bronchitis, and pneumonia.

[0003] Children's respiratory system has unique anatomical and physiological characteristics. Anatomically, infants and young children have relatively short nasal cavities and narrow posterior nasal passages, lack nasal hairs, and have delicate mucous membranes rich in blood vessels, making them highly susceptible to infection and nasal obstruction. Their trachea and bronchi are relatively narrow, with soft cartilage and a lack of elastic tissue, resulting in weak support. They also have insufficient mucus secretion and poor ciliary movement, leading to a weaker ability to clear secretions, thus making them prone to infection and airway obstruction. Physiologically, children have a faster respiratory rate: newborns approximately 40-45 breaths / minute, infants approximately 30-40 breaths / minute, toddlers approximately 25-30 breaths / minute, and preschool children approximately 20-25 breaths / minute, with the younger the child, the faster the respiratory rate. Their respiratory center is not fully developed, making them prone to irregular breathing rhythms and even sleep apnea. Their vital capacity is smaller, approximately 50-70 ml / kg, and tidal volume is approximately 6-10 ml / kg, with these values ​​decreasing with age. Airway resistance is significantly greater than in adults due to the smaller diameter of the airways. These physiological characteristics make the requirements for nebulization parameters and breathing coordination more stringent for children during nebulization therapy.

[0004] However, most nebulizer products on the market are designed primarily for adult use, failing to adequately consider the unique physiological and psychological needs of children. In clinical practice, ordinary nebulizers present several problems: First, their cold appearance, buzzing noise, and the need for a mask covering the mouth and nose often induce strong fear and resistance in children aged 1-12, leading to crying and rapid breathing during treatment. Second, crying or rapid, shallow breathing in children severely affects the deposition efficiency of nebulized medication in the lungs. Studies have shown that when the respiratory rate is fast and the inspiratory volume is small, the amount of drug deposited in the lungs is significantly reduced, and treatment may even be interrupted due to crying. Third, fear and anxiety can also have long-term negative impacts on children's future medical behavior, potentially leading to medical phobia and affecting their cooperation with subsequent treatments.

[0005] To address the aforementioned technical deficiencies, a solution is proposed. Summary of the Invention

[0006] The purpose of this invention is to address the issue that most nebulizer products currently on the market are designed primarily for adult use, failing to adequately consider the unique physiological and psychological needs of children. In clinical practice, ordinary nebulizers present several problems: First, their cold appearance, buzzing noise, and the need for a mask covering the mouth and nose often induce strong fear and resistance in children aged 1-12, leading to incessant crying and rapid breathing during treatment. Second, crying or rapid, shallow breathing in children severely affects the deposition efficiency of nebulized medication in the lungs. Studies have shown that when the respiratory rate is fast and the inspiratory volume is small, the amount of drug deposited in the lungs is significantly reduced, and treatment may even be interrupted due to crying. Third, fear and anxiety can also have long-term negative impacts on children's future medical behavior, potentially leading to medical phobia and affecting their cooperation with subsequent treatments.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a child-friendly intelligent nebulizer with quantifiable guidance on breathing methods, comprising a nebulizer host, speakers at both the front and rear ends of the nebulizer host, an LED light on the left side of the nebulizer host, and a control chip embedded in the nebulizer host, wherein the control chip has a built-in control system for the child-friendly intelligent nebulizer.

[0008] The control system of the children's intelligent atomizer includes a data acquisition unit, a standard preset unit, a user analysis unit, an instruction receiving unit, and an intelligent control unit; The data acquisition unit is used to collect the user's respiratory rate and body temperature data in real time through an external monitor, and send the collected data to the user analysis unit; The standard preset unit is used to preset the user's respiratory rate and body temperature values ​​according to the age mode selected by the user, integrate them into a standard database, and send them to the user analysis unit. The user analysis unit is used to receive real-time respiratory rate and body temperature data of users and a standard database through a mobile terminal, and compare and analyze the collected real-time respiratory rate and body temperature data of users with the standard database to identify the user's usage and generate control commands. The mobile terminal will issue corresponding control commands according to the data range of the collected temperature and respiratory rate data in the age group selected by the user. The instruction receiving unit is used to receive control instructions generated by the user analysis unit via wireless transmission technology; The intelligent control unit is used to intelligently control the child-friendly smart nebulizer according to the received control commands.

[0009] Furthermore, an extension tube is provided at the center of the left side of the atomizing host, and a face mask is provided at the other end of the extension tube.

[0010] Furthermore, the standard database specifically includes: Age and respiratory rate segmentation: For users aged 1-3 years, the standard respiratory rate is 24-40 breaths / min, the rate of excessively fast breathing is 40-45 breaths / min, the rate of normal to slightly fast breathing is 35-40 breaths / min, and the rate of normal to slightly slow breathing is 24-35 breaths / min. For users aged 4-6 years, the standard respiratory rate is 22-34 breaths / min, the rate of excessively fast breathing is 32-36 breaths / min, the rate of normal to slightly fast breathing is 28-32 breaths / min, and the rate of normal to slightly slow breathing is 22-28 breaths / min. For users aged 7-12 years, the standard respiratory rate is 18-30 breaths / min, the rate of excessively rapid breathing is 28-33 breaths / min, the rate of normal to slightly rapid breathing is 24-28 breaths / min, and the rate of normal to slightly slow breathing is 18-24 breaths / min. When the respiratory rate is not less than 42 breaths / min and the body temperature is not less than 37.2 degrees Celsius, the user is judged to have rapid breathing and high body temperature.

[0011] Furthermore, the control commands include lighting control commands, voice control commands, and music control commands.

[0012] Furthermore, the lighting control commands specifically include: When breathing is too rapid, the LED light flashes red. When breathing is normal but slightly rapid, the LED light will flash yellow. When breathing is normal but slow, the green LED light will remain on. When breathing is rapid and body temperature is high, the red LED light will remain on.

[0013] Furthermore, the voice control commands specifically include: It emits a gentle warning sound when breathing is too rapid; When breathing is normal but slightly rapid, a child's voice is emitted. When breathing is normal but slow, it emits an encouraging prompting sound; It will issue a warning voice when the patient is breathing rapidly and has a high body temperature.

[0014] Furthermore, the music control commands are segmented according to the user's age and music is played through the speaker.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: This children's smart nebulizer and control system, which provides quantifiable guidance on breathing techniques, enhances interactivity through voice guidance, soothes emotions, guides breathing, and explains the nebulization principle. Music naturally calms and relaxes children, while lights alert to abnormal situations (such as crying), creating a conducive atmosphere. This forms a system combining "emotional soothing + breathing guidance + educational explanation," reducing children's fear of treatment. Furthermore, compared to ordinary nebulizers, it provides guidance on correct breathing methods, leading to better drug deposition. In addition, customizable music selection and a cute, child-friendly design make the nebulizer more like a musical toy, diverting children's attention from the discomfort of treatment and increasing cooperation.

[0018] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0019] like Figure 1As shown, a child-friendly smart nebulizer that can quantify and guide breathing methods includes a nebulizer host 1, speakers 2 at both the front and rear ends of the nebulizer host 1, an LED light 3 on the left side of the nebulizer host 1, a control chip embedded in the nebulizer host 1, and the control chip has a built-in control system for the child-friendly smart nebulizer. An extension tube 5 is located at the center of the left side of the nebulizer host 1, and a mask 4 is located at the other end of the extension tube 5. Example 2:

[0020] like Figure 2 As shown, a control system for a child-friendly smart nebulizer that can quantify and guide breathing patterns first uses a data acquisition unit to collect the user's breathing rate and body temperature data in real time through an external monitor, and then sends the collected data to the user analysis unit. It should be noted that the monitor can be attached to the user's clothing or body surface (it can be worn imperceptibly), collect initial data and transmit it to a mobile device.

[0021] Then, the standard preset unit presets the user's respiratory rate and body temperature values ​​according to the age mode selected by the user, integrates them into a standard database, and sends them to the user analysis unit. The standard database specifically includes: Age and respiratory rate segmentation: For users aged 1-3 years, the standard respiratory rate is 24-40 breaths / min, the rate of excessively fast breathing is 40-45 breaths / min, the rate of normal to slightly fast breathing is 35-40 breaths / min, and the rate of normal to slightly slow breathing is 24-35 breaths / min. For users aged 4-6 years, the standard respiratory rate is 22-34 breaths / min, the rate of excessively fast breathing is 32-36 breaths / min, the rate of normal to slightly fast breathing is 28-32 breaths / min, and the rate of normal to slightly slow breathing is 22-28 breaths / min. For users aged 7-12 years, the standard respiratory rate is 18-30 breaths / min, the rate of excessively rapid breathing is 28-33 breaths / min, the rate of normal to slightly rapid breathing is 24-28 breaths / min, and the rate of normal to slightly slow breathing is 18-24 breaths / min. When the respiratory rate is not less than 42 breaths / min and the body temperature is not less than 37.2 degrees Celsius, the user is judged to have rapid breathing and high body temperature.

[0022] Next, the user analysis unit receives the user's real-time respiratory rate and body temperature data, as well as a standard database, via the mobile device. It compares and analyzes the collected real-time respiratory rate and body temperature data with the standard database to identify the user's usage and generate control commands. It should be noted that the mobile device issues corresponding commands (voice, music, lights) based on the collected temperature and respiratory rate data within the data range selected by the user's age group; custom music playback is also possible. The mobile device transmits commands and information to the control chip via a Bluetooth wireless connection. The control chip then controls the nebulizer's speaker 2 to play sound and the LED light 3 to change its lighting.

[0023] Control commands include lighting control commands, voice control commands, and music control commands.

[0024] The lighting control commands specifically include: When breathing is too rapid, LED light 3 will flash red. When breathing is normal but slightly rapid, LED light 3 will flash yellow. When breathing is normal but slow, LED light 3 (green light) will remain on. When breathing is rapid and body temperature is high, LED light 3 (red light) will remain on.

[0025] Voice control commands specifically include: When breathing too fast, it will emit a gentle prompting sound, such as "Inhale slowly, like smelling the fragrance of flowers~"; When breathing is normal but slightly rapid, speak in a child's voice, such as, "Take a deep, slow breath and let more white smoke into your lungs!" When breathing is normal but slow, give encouraging prompts, such as "You're breathing well, you're great! The medicine is fighting the virus!"; When the baby is breathing rapidly and has a high body temperature, issue a warning voice message, such as "Baby, don't cry, let's rest for a bit" or "Baby is crying, please comfort the baby."

[0026] Music control commands are segmented according to the user's age and play music through speaker 2. Specifically, for toddlers (1-3 years old), Bach's "Air on the G String" is played (a soothing 60 BPM rhythm and continuous bass line simulate the sound of a mother's heartbeat; clinical studies have shown that this can reduce cortisol levels in toddlers by 27%). Play the first movement of Vivaldi's "The Four Seasons: Spring" for preschool children (3-6 years old). (The allegro tempo of 98 BPM combined with birdsong sounds helps to naturally reduce the child's breathing rate to 20 breaths per minute.) Play Pachelbel's Canon in D major for school-aged children (6-12 years old). (The stable rhythm and round structure at 74 BPM can significantly reduce respiratory resistance in children with asthma.)

[0027] Finally, the command receiving unit receives control commands generated by the user analysis unit via wireless transmission technology. Simultaneously, the intelligent control unit intelligently controls the child-friendly smart nebulizer based on the received control commands.

[0028] This invention enhances interactivity through voice guidance, soothing emotions, guiding breathing, and explaining the nebulization principle. Music naturally calms and relaxes children, while lights alert to abnormal situations (such as crying), creating a conducive atmosphere. This forms a system of "emotional soothing + breathing guidance + educational explanation," reducing children's fear of treatment. Furthermore, compared to ordinary nebulizers, it guides correct breathing techniques, leading to better drug deposition. In addition, customizable music selection and a cute, child-friendly design make the nebulizer more like a musical toy, diverting children's attention from the discomfort of treatment and increasing cooperation.

[0029] The size of the interval and threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by those skilled in the art for each set of sample data; as long as it does not affect the ratio between the parameter and the quantized value.

[0030] The above formulas are all dimensionless calculations. The formulas are derived from software simulations based on a large amount of collected data to obtain the most recent real-world results. The preset parameters in the formulas are set by those skilled in the art according to the actual situation. The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
