Description

Technical Field

[0001] This invention relates to the field of nebulizer technology, specifically to a pacifier-type nebulizer for newborns. Background Technology

[0002] Currently, nebulized inhalation therapy for respiratory diseases in clinical practice commonly uses mask-type or mouth-type nebulizers. These devices are mainly suitable for adult and pediatric patients who are capable of active cooperation, allowing them to administer medication via nebulization by biting the nozzle or wearing a mask. However, newborns, due to their immature physiological development and extremely low ability to cooperate, cannot adapt to the structure of conventional nebulizers. In clinical practice, only modified small pediatric masks can be used to cover the mouth and nose of newborns for nebulization therapy.

[0003] This traditional method has many inherent drawbacks: newborns strongly resist having a foreign object covering their mouth and nose, and are prone to crying and struggling, causing the mask to shift and fall off, resulting in extremely poor treatment cooperation; the mask does not fit the newborn's face well enough, leading to a large amount of leakage of medication mist, and the medication utilization rate is only 30%-40%, causing serious waste of medical resources; the mask covering the mouth and nose can easily affect the newborn's normal breathing, and is more likely to cause choking, suffocation and other safety risks when the newborn is crying, and repeated interruptions will prolong the treatment time and increase the newborn's stress response; at the same time, the mask material is relatively hard and needs to be fixed with straps, which can easily cause pressure and friction damage to the newborn's delicate skin.

[0004] Given the delicate respiratory mucosa and weak resistance of newborns, the incidence of respiratory diseases such as pneumonia and bronchiolitis is relatively high. Nebulized inhalation has the advantages of rapid onset of action, high local concentration and few systemic side effects, and has become the preferred treatment for respiratory diseases in newborns. Therefore, the existing mask nebulizers can no longer meet the clinical treatment needs of safety, efficiency and comfort. There is an urgent need to develop a special nebulization device that is adapted to the physiological characteristics of newborns, can improve cooperation and drug utilization, and eliminate safety hazards. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pacifier-type nebulizer specifically for newborns. This nebulizer utilizes the newborn's sucking reflex to achieve active drug delivery, effectively solving problems in the prior art such as newborn resistance and crying during treatment, mask displacement and detachment, serious drug mist leakage, high risk of suffocation and coughing, and skin susceptibility to friction and pressure damage. It significantly improves the compliance rate, drug utilization rate, and treatment safety of nebulization therapy, reduces the waste of medical resources, and enhances the comfort and clinical efficacy of newborn nebulization therapy.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A pacifier-type nebulizer for newborns includes a nebulizer main unit, a connecting pipe, a medicine storage chamber, and a pacifier-type mist outlet; the nebulizer main unit, the connecting pipe, the medicine storage chamber, and the pacifier-type mist outlet are detachably and sealed through a sealed interface, ensuring no mist leakage or medicine seepage in the assembled state, and can be cleaned, disinfected, or replaced individually after disassembly; the nebulizer main unit is a miniature ultrasonic nebulizer structure, internally integrating an ultrasonic nebulizer plate, a nebulizer power adjustment knob, a silent pump, function control buttons, and a power supply module, with the output droplet diameter precisely controlled at 3–5 μm; the pacifier-type mist outlet adopts a breast-milk-inspired streamlined ergonomic structure, adapting to the physiological curve of the newborn's oral cavity, and utilizing the newborn's sucking reflex to achieve active sucking nebulization drug delivery.

[0007] Furthermore, the power adjustment range of the nebulizer is 5–10W, which can be adjusted according to the newborn's weight and condition level; the main unit shell is made of ABS flame-retardant material with an IPX4 protection rating and a smooth surface that is easy to clean; the side of the main unit is provided with a nebulizer output port, and the outer side of the output port is provided with a sealing groove and positioning protrusions. The interface is internally fitted with a medical nitrile rubber sealing gasket for quick insertion and sealing with the connecting tube.

[0008] Furthermore, the connecting tube is integrally extruded from medical-grade silicone material, with a length of 35cm and a diameter of 5mm. The tube wall is flexible and has anti-bending properties. The inner wall of the tube is polished to reduce drug residue, can withstand high temperature and high pressure sterilization, and can be reused. The two ends of the connecting tube are respectively formed with a proximal sealing connector and a distal threaded connector. The proximal sealing connector is matched and locked with the output port of the nebulizer, and the distal threaded connector is used for threaded sealing connection with the pacifier-type mist outlet.

[0009] Furthermore, the medication storage chamber has a capacity of 8ml and is injection molded from transparent medical-grade PP material. The medication storage chamber includes a chamber body, and the side wall of the chamber body is provided with graduation lines for accurately adding and observing the amount of 3-5ml of neonatal nebulized medication. The top of the chamber body is provided with a spiral sealing cap, and a one-way vent valve is installed in the center of the sealing cap. The one-way vent valve only allows external air to enter the chamber to balance the negative pressure, while preventing the medication and mist from overflowing. A threaded connection interface for connecting to the connecting pipeline is also provided at the center of the bottom of the chamber body.

[0010] Furthermore, the bottom of the liquid medicine storage chamber is equipped with an integrated quick-connect sealing interface with a sealing gasket inside, which can be quickly connected to the inner wall of the chamber to ensure that the liquid medicine smoothly enters the atomization area and maintains the atomization process continuously, stably and without interruption.

[0011] Furthermore, the pacifier-type mist outlet is formed by sealing and integrating three parts: the nipple head, the nipple base, and the connecting interface; the nipple head is a hemispherical soft structure with a length of 2.8cm and a diameter of 1.8cm, made of medical-grade liquid silicone with a Shore hardness of 20-30A, which is odorless, non-allergenic, and non-cytotoxic.

[0012] Furthermore, a through-type hollow mist channel is opened inside the nipple, which extends from the interface end to the top of the nipple. At the end, four precision mist outlet holes with a diameter of 0.4mm are evenly distributed. All the mist outlet holes are directed towards the inside of the oral cavity to avoid direct stimulation of the oral mucosa by the mist.

[0013] Furthermore, the nipple base is an arc-shaped flat structure with a diameter of 4.5cm, made of medical-grade ABS material, with smooth rounded edges, which can stably fit the skin around the newborn's lips and prevent fogging from leaking out from the corners of the mouth.

[0014] Furthermore, the inner wall of the threaded connection interface is provided with an internal thread and a sealing gasket groove. A medical nitrile rubber sealing gasket is embedded in the groove and precisely screwed into the external thread at the far end of the connecting pipe to form a two-stage sealing structure.

[0015] Furthermore, the overall weight of the device does not exceed 200g, making it suitable for newborns weighing 1–5kg. It can be used in newborn incubators, cribs, and hospital wards.

[0016] Furthermore, all components of the device that come into contact with the medication and the newborn's mouth comply with GB15980-2018 "Hygienic Standard for Disposable Medical Products", possess good biocompatibility, and are non-cytotoxic and non-sensitizing.

[0017] Furthermore, the device does not cover the newborn's mouth and nose during nebulized drug delivery, does not affect normal breathing, achieves a drug utilization rate of 75%–85%, and a single treatment time of 5–10 minutes.

[0018] Furthermore, the nebulizer output droplets can effectively reach the terminal bronchioles and alveoli of newborns, avoiding choking caused by excessively large droplets and exhalation when the droplets are too small, thus significantly reducing the incidence of choking.

[0019] Compared with existing technologies, the beneficial effects of this solution are as follows: This invention solves the clinical pain point of poor cooperation in neonatal nebulization therapy. By utilizing the newborn's natural sucking reflex, the newborn actively sucks on the nebulizer-type nozzle, significantly reducing the incidence of crying and struggling. No mask covering or external straps are required for fixation, and the operation can be completed by a single person. The treatment cooperation rate has increased from 30% to 92%, while the treatment time per session has been shortened from 15-20 minutes to 5-10 minutes, significantly simplifying the operation process and improving the efficiency of clinical diagnosis and treatment.

[0020] This invention significantly improves drug utilization and reduces waste of medical resources. The nipple fits tightly against the newborn's mouth, and the mist outlet is directed towards the inside of the respiratory tract, effectively preventing leakage of mist from the corners of the mouth and facial gaps. Drug utilization is greatly increased from 30%–40% to 75%–85%, an average increase of 121.5%. Combined with a precise droplet diameter design of 3–5μm, it ensures that the drug reaches the newborn's terminal bronchus and alveoli directly, improving the therapeutic effect while significantly reducing drug loss.

[0021] This invention completely eliminates the safety hazards of traditional mask nebulization and improves user comfort. The nipple-like structure does not cover the mouth and nose, does not affect normal breathing, and completely eliminates the risk of suffocation. The medical-grade liquid silicone nipple is soft and the curved base fits the skin without pressure or friction damage, reducing the incidence of adverse events from 15%–20% to 0. The silent main unit operates with a noise level of ≤30dB, reducing sound and light stimulation. The entire nebulization drug delivery process is safer and more comfortable, and is suitable for the delicate physiological characteristics of newborns and multiple clinical use scenarios.

[0029] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be described in further detail below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the embodiments.

[0031] Example: As attached Figure 1-6 As shown, a pacifier-type nebulizer for newborns is mainly suitable for nebulized inhalation treatment of respiratory diseases in newborns weighing 1-5kg. The whole unit consists of four main modules: nebulizer main unit, connecting tubing, medicine storage chamber, and pacifier-type mist outlet. The components are detachably connected by sealed interfaces, and there is no mist leakage or medicine leakage after assembly. After disassembly, each component can be cleaned, disinfected, or replaced individually. The whole unit weighs no more than 200g and can be safely used in various clinical scenarios such as newborn incubators, cribs, and wards.

[0032] The nebulizer unit is the core of this nebulizer, generating and powering the atomization process. It employs micro-ultrasonic atomization technology and integrates an ultrasonic atomizing plate, a power adjustment knob, a silent pump, function control buttons, and a power supply module. The unit's power adjustment range is 5–10W, allowing for graded adjustment based on the newborn's weight and condition. The output droplet diameter is precisely controlled at 3–5μm, ensuring effective delivery of medication droplets to the newborn's terminal bronchioles and alveoli, while preventing excessively large droplets from causing choking or excessively small droplets from being exhaled. The unit features a built-in silent pump with operating noise ≤30dB, minimizing auditory stimulation for newborns. The unit's casing is injection-molded from flame-retardant ABS material, with a smooth, easy-to-clean surface and an IPX4 protection rating, providing drop and splash resistance, suitable for complex clinical environments. The nebulizer output port is located on the side of the unit, with a sealing groove and positioning protrusions on the outside. A medical-grade nitrile rubber sealing gasket is embedded inside the interface for quick connection to the connecting tubing and a reliable seal, ensuring stable and continuous droplet output.

[0033] The connecting tubing serves as the droplet delivery channel, integrally extruded from medical-grade silicone. It is 35cm long and 5mm in diameter, with a flexible wall and excellent bending resistance, allowing it to move with the newborn's position without bending, clogging, or breaking. The inner wall of the tubing is polished, smooth and without dead corners, significantly reducing drug residue. It can withstand high-temperature and high-pressure sterilization and is reusable. Both ends of the connecting tubing have a proximal sealing connector and a distal threaded connector. The proximal sealing connector has a groove and sealing ring groove on its inner wall that match the output port of the nebulizer, automatically locking and achieving a primary seal after insertion. The distal threaded connector has a standard external thread on its outer wall for a threaded seal connection with the pacifier-type mist outlet, ensuring no mist leakage and no drug backflow throughout the entire process.

[0034] The medication storage chamber, with a capacity of 8ml, is the component for carrying the medication and stabilizing air pressure. It is injection-molded from transparent medical-grade PP material, and the side wall of the chamber has clear graduations for accurate addition and observation of the 3-5ml volume of routine neonatal nebulization medication. The top of the chamber has a screw-on sealing cap with a one-way vent valve at its center. This valve allows only external air to enter the chamber, balancing the negative pressure during nebulization, ensuring a stable medication supply, and preventing medication and mist from overflowing from the cap. The bottom of the chamber features an integrated quick-connect sealing interface with an internal sealing gasket. This interface allows for quick connection to the middle section of the connecting tubing, ensuring smooth medication flow into the nebulization area and maintaining continuous, stable, and uninterrupted nebulization. The threaded connection interface is located at the center of the bottom of the chamber. Its inner wall has internal threads and a groove for a sealing gasket. A medical-grade nitrile rubber sealing gasket is embedded in the groove and precisely screws into the external thread at the distal end of the connecting tubing for a two-stage sealing structure.

[0035] The pacifier-style mist outlet is the core innovative component of this nebulizer. It adopts a streamlined ergonomic structure inspired by a breastfeeding pacifier, and is formed by a sealed, integrated design of the nipple head, nipple base, and connecting interface. The nipple head is a hemispherical soft structure, 2.8cm in length and 1.8cm in diameter, made of medical-grade liquid silicone with a Shore hardness of 20-30A. It is odorless, non-allergenic, and non-cytotoxic, with a smooth, rounded surface that conforms to the physiological curve of a newborn's mouth, aligning with the newborn's natural sucking reflex. The nipple base is a 4.5cm diameter, arc-shaped flat structure made of medical-grade ABS material, with smooth, rounded edges to ensure a stable fit around the newborn's lips and prevent mist leakage from the corners of the mouth. The nipple head features a through-type hollow mist channel extending from the interface end to the tip of the nipple head, with four evenly distributed 0.4mm precision mist outlets at the end. These outlets direct mist towards the inside of the mouth, avoiding direct irritation to the oral mucosa. Newborns can naturally latch onto the nipple through their sucking reflex, eliminating the need for additional straps. The nebulized medication is administered without covering the mouth and nose or affecting normal breathing; it is delivered during spontaneous sucking and breathing, resulting in high patient compliance and good safety. In this embodiment, all components in contact with the medication and the newborn's mouth are made of medical-grade materials conforming to GB15980-2018 "Hygienic Standard for Disposable Medical Products," exhibiting good biocompatibility, non-cytotoxicity, and non-sensitizing properties, thus meeting the safety requirements for clinical use in newborns.

[0036] The device of this invention is highly adaptable to the physiological characteristics and treatment needs of newborns, achieving high adaptability, high safety, high drug utilization, and high comfort in nebulization therapy. It simplifies clinical procedures, shortens treatment time, and reduces medical risks and resource waste, providing a dedicated and reliable solution for nebulization therapy of neonatal respiratory diseases. Compared with existing technologies, this embodiment has significant advancements, as shown in Table 1 below:

[0037] Table 1. Technical Effects Compared with Existing Technologies

[0038] Regarding cooperation, existing modified pediatric masks easily induce crying and struggling in newborns, resulting in extremely low cooperation. This embodiment utilizes the sucking reflex to encourage newborns to actively suckle, leading to extremely high cooperation. Regarding drug utilization, existing technologies only achieve 30%–40%, while this embodiment increases it to 75%–85%. Regarding safety risks, existing technologies pose risks of suffocation, coughing, and skin damage, while this embodiment has no suffocation risk, an extremely low incidence of coughing, and no skin damage. Regarding treatment time, existing technologies require 15–20 minutes due to interruptions and repeated operations, while this embodiment requires only 5–10 minutes for continuous treatment. Regarding operational difficulty, existing technologies require multiple people to assist in fixation and are complex to operate, while this embodiment can be completed by a single person and is simple to operate.

[0039] In a clinical trial involving 100 newborns, the compliance rate reached 92%, far exceeding the 30% of existing technologies; the average drug utilization rate was 81.3%, an increase of 121.5% compared to the 36.7% of existing technologies; the average treatment time per session was 7.2 minutes, a reduction of 60.9% compared to the 18.5 minutes of existing technologies; no adverse events such as suffocation, aggravated coughing, or skin damage occurred during the trial period, with an adverse event rate of 0%, significantly better than the 15%–20% adverse event rate of existing technologies. The overall treatment efficacy, safety, and clinical applicability have been comprehensively improved.

[0040] Working Principle: Before use, place the nebulizer unit stably and connect it to the power supply. Open the screw-sealed cap on top of the medication storage chamber and inject the nebulized medication into the chamber according to the dosage required for a single treatment for the newborn. After confirming that the medication volume meets the standard requirement of 3-5ml through the transparent chamber and the scale lines, tighten the sealing cap and ensure that the one-way vent valve is in normal ventilation mode. Then, align and insert the proximal sealing connector of the connecting tube with the nebulizer output port on the top of the nebulizer unit, relying on the slot and sealing gasket to form a tight seal. Then, tighten and lock the threaded connector at the distal end of the tube with the threaded connection interface at the bottom of the pacifier-type mist outlet. Check all connections one by one to ensure there is no looseness or mist leakage. Finally, adjust the parameters on the nebulizer unit panel according to the newborn's weight and condition, setting the power to the 5-10W range and the droplet diameter to 3-5μm. This completes the entire assembly and debugging preparation process. For example: for newborns weighing 1-2kg, select 5W power and 3μm droplets; for newborns weighing 3-5kg, select 8W power and 4-5μm droplets.

[0041] After the nebulizer is turned on, the miniature ultrasonic nebulizer component efficiently atomizes the medication delivered in the medication tank into uniform droplets of a size suitable for the newborn's respiratory tract. Driven stably by the silent pump, the droplets are continuously delivered along the connecting tubing to the pacifier-style mist outlet. The droplets are guided by the hollow channel inside the nipple and smoothly sprayed out from the precision mist outlet at the end into the inside of the mouth. After the medical staff or parents gently place the pacifier-style mist outlet into the newborn's mouth, the newborn will suck on the nipple involuntarily through the natural sucking reflex. With the coordinated action of normal breathing and sucking, the medication droplets directly enter the respiratory tract and reach the terminal bronchi and alveoli. No mask or external fixation is required throughout the process, which does not affect breathing and has no risk of choking. After a single treatment lasts 5-10 minutes, the nebulizer is turned off. The nebulizer, connecting tubing, medication storage tank, and pacifier-style mist outlet are then disassembled in sequence. All reusable parts are sterilized by high temperature and high pressure, dried, and stored for later use, completing the entire nebulization treatment and cleaning process.

[0042] The above specific embodiments are merely explanations of the present invention and are not intended to limit the present invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
