Description

Technical Field

[0001] This application belongs to the field of medical devices, specifically relating to a nebulizer for pediatric use. Background Technology

[0002] A medical nebulizer is a medical device that transforms liquid medications into tiny droplets, which are then inhaled by the patient, allowing the medication to act directly on the respiratory tract and lungs for local or systemic treatment. A medical nebulizer typically consists of a main unit (providing the power for nebulization), a tubing, a nebulizer cup (containing the medication), and a breathing mask. The nebulizer cup is usually directly connected to the breathing mask to minimize droplet loss during delivery and ensure efficient delivery of the medication to the respiratory tract.

[0003] During nebulizer therapy, to ensure even distribution of the medication, efficient atomization, reduced residue and contamination, and to maintain the therapeutic effect, the nebulizer cup must be kept relatively upright. Excessive tilting will lead to decreased atomization efficiency, medication waste, and weakened therapeutic effect.

[0004] Current technology, with its connection structure between the nebulizer cup and the breathing mask, requires the patient's upper body to remain upright during use. This is difficult for some patients who are physically weak (e.g., in cases of severe respiratory infections) or young children to maintain an upright position for extended periods, making it unsuitable for use and requiring assistance from others. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a pediatric nebulizer with an optimized connection structure between the nebulizer cup and the breathing mask, which can be used when the patient's body is in a certain tilted position.

[0006] This application provides a pediatric nebulizer, comprising: a breathing mask, a connecting structure, and a nebulizer cup connected in sequence;

[0007] The connection structure includes a connecting sleeve connected to the breathing mask, a connector head with an embedded spherical surface at one end of the connecting sleeve, and a positioning sleeve fitted onto the connecting sleeve. The connector head can deflect in multiple directions with the end that mates with the connecting sleeve as the rotation center, and the positioning sleeve is used to limit the deflection angle range of the connector head. The end of the connector head away from the connecting sleeve is connected to the nebulizer cup.

[0008] Optionally, the inner side of one end of the connecting sleeve is an annular spherical surface, and the connector includes a through spherical structure at one end, which is embedded in the inner side of one end of the connecting sleeve and slides in cooperation with the annular spherical surface.

[0009] Optionally, the annular spherical surface of the connecting sleeve covers the through-type spherical structure.

[0010] Optionally, the positioning sleeve includes a reduced-diameter ring at one end away from the connecting sleeve, and a conical spring is provided between the reduced-diameter ring and one end of the connecting sleeve. The small-diameter end of the conical spring is attached to the surface of the through-type spherical structure, so that the through-type spherical structure can elastically fit against the annular spherical surface. The space between the reduced-diameter ring and the connector is the deflection angle range of the connector.

[0011] Optionally, the deflection angle of the connector is in the range of 20°-60°.

[0012] Optionally, the outer periphery of the connecting sleeve is provided with multiple anti-slip protrusions.

[0013] Optionally, the connector further includes a connecting nozzle connected to the through-type spherical structure, the connecting nozzle being inserted into the atomizing cup.

[0014] Optionally, a weight-adding ring is fitted on the bottom side of the atomizing cup.

[0015] Optionally, the breathing mask is provided with straps.

[0016] Optionally, the pediatric nebulizer also includes a tubing connected to the bottom of the nebulizer cup and a main unit connected to the tubing.

[0017] The beneficial effect of this application is that the embedded spherical fit between the connector and the connecting sleeve forms a hinge structure similar to a universal joint, allowing the connector to freely rotate in multiple directions around the center of the sphere. When the patient is in a semi-recumbent, reclining, or lateral position, the nebulizer cup can automatically adjust its angle to maintain a vertical position as much as possible, ensuring sufficient atomization of the medication, reducing residue, and maintaining the therapeutic effect. To prevent excessive rotation from causing catheter twisting or loosening of the connection, an external positioning sleeve is provided. The shape of its inner cavity or limiting protrusion can limit the deflection range of the connector, improving structural stability while ensuring flexible adjustment. This design effectively solves the problem of traditional nebulizers requiring specific patient positions, making it particularly suitable for weak or young children who have difficulty sitting for long periods, improving comfort and safety during use.

Detailed Implementation

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] like Figure 1-4 As shown, this application provides a pediatric nebulizer, comprising: a breathing mask 100, a connecting structure 200, and a nebulizing cup 300 connected in sequence; the connecting structure 200 includes a connecting sleeve 210 connected to the breathing mask 100, a connector 220 with one end of the connecting sleeve 210 embedded in a spherical surface, and a positioning sleeve 230 sleeved on the connecting sleeve 210. The connector 220 deflects in multiple directions with the end that mates with the connecting sleeve 210 as the rotation center, and the positioning sleeve 230 is used to limit the deflection angle range of the connector 220. The end of the connector 220 away from the connecting sleeve 210 is connected to the nebulizing cup 300.

[0025] Compared with existing technologies, the pediatric nebulizer provided in this application forms a hinge structure similar to a universal joint through the embedded spherical fit between the connector 220 and the connecting sleeve 210, allowing the connector 220 to freely deflect in multiple directions around the center of the sphere. When the patient is in a semi-recumbent, reclining, or lateral position, the nebulizing cup 300 can automatically adjust its angle to maintain a vertical position as much as possible, ensuring sufficient atomization of the medication, reducing residue, and maintaining the therapeutic effect. To prevent excessive rotation from causing the catheter 400 to twist or the connection to loosen, an external positioning sleeve 230 is provided. The shape of its inner cavity or limiting protrusion can limit the deflection range of the connector 220 (e.g., within ±30°), improving structural stability while ensuring flexible adjustment. This design effectively solves the problem of traditional nebulizers requiring specific patient positions, and is particularly suitable for weak or young children who have difficulty sitting for long periods, improving comfort and safety during use.

[0026] It should be noted that the connecting sleeve 210, connector 220, and positioning sleeve 230 can be made of transparent, corrosion-resistant, and easily moldable plastic materials such as medical-grade polycarbonate (PC) and polypropylene (PP), or polytetrafluoroethylene (PTFE) for easy observation of the internal components. A silicone sealing ring can be added to the spherical mating area to prevent air leakage and provide appropriate damping for smoother angle adjustment. The connecting sleeve 210 and the breathing mask 100, and the connector 220 and the nebulizer cup 300, can be connected by threads or snap-fit ​​for easy disassembly, cleaning, and component replacement. The entire connecting structure 200 can be used as an independent module, compatible with common nebulizer cup 300 and mask models on the market, improving versatility, or it can be shipped as an integrated nebulizer device, integrating the main unit 500, tubing 400, nebulizer cup 300, connecting structure 200, and mask.

[0027] In one possible implementation, the inner side of one end of the connecting sleeve 210 is an annular spherical surface 211, and the connector 220 includes a through spherical structure 221 located at one end, which is embedded in the inner side of one end of the connecting sleeve 210 and slides in cooperation with the annular spherical surface 211.

[0028] Specifically, an elastic sealing ring is added to the spherical mating area to enhance airtightness and provide damping, making angle adjustment smoother. The annular spherical surface 211 and the spherical structure are injection molded with high precision to ensure smooth rotation and appropriate gaps. The through-type spherical structure 221 can rotate freely within the annular spherical surface 211, allowing the connector 220 to deflect around the center of the sphere in multiple directions. When the patient's position changes, the nebulizer cup 300 end can adaptively adjust its angle to adapt to different patient positions, while the breathing mask 100 end remains in close contact with the face to ensure unobstructed airflow. The through-type design ensures a continuous and seamless drug mist pathway, reducing drug residue.

[0029] In one possible implementation, the annular spherical surface 211 of the connecting sleeve 210 encloses the through spherical structure 221.

[0030] Specifically, the connecting sleeve 210 and the spherical structure adopt a clamp-type mating structure, which is equivalent to an elastic snap-fit ​​structure. The annular spherical surface 211 of the connecting sleeve 210 is designed to have a certain degree of elasticity. During assembly, the through-type spherical structure 221 is pressed in by slight expansion, and the connection is achieved by material rebound. Alternatively, a split clamp design can be adopted, dividing the connecting sleeve 210 into two halves, which are closed by threads or snaps to wrap and fix the spherical structure, making maintenance and replacement convenient. An annular boss or groove is set inside the annular spherical surface 211 as a limiting shoulder, which mates with the edge of the through-type spherical structure 221 to achieve axial limiting and prevent it from coming off during use. At the same time, an O-ring can be embedded in the clamp contact surface to enhance airtightness and adjust rotational damping, making angle adjustment smoother and more controllable. In terms of materials, the connecting sleeve 210 can be made of elastic medical-grade TPE or soft PC, while the spherical structure of the connector 220 is made of hard PP or PC, taking into account structural strength, sealing performance and assembly convenience.

[0031] This clamp-type mating structure offers multiple advantages: its design effectively prevents the connector 220 from accidentally dislodging during multi-directional deflection, ensuring connection integrity and safety; by rationally controlling the clamping force and spherical fit precision, it maintains good airtightness while ensuring flexible rotation, preventing atomized gas leakage and ensuring efficient drug mist delivery; the use of elastic snap-fit ​​or interference fit allows for quick assembly and disassembly of the connector 220 and connecting sleeve 210, significantly simplifying the production process and facilitating daily cleaning, disinfection, and component replacement; furthermore, the clamp structure itself acts as a mechanical limiter, further restricting the deflection angle in conjunction with the external positioning sleeve 230, effectively preventing the conduit 400 from twisting or the connection from loosening due to excessive rotation, thus improving the overall stability and reliability of the structure.

[0032] In one possible implementation, the positioning sleeve 230 includes a reduced-diameter ring 231 at one end away from the connecting sleeve 210. A conical spring 240 is disposed between the reduced-diameter ring 231 and one end of the connecting sleeve 210. The small-diameter end of the conical spring 240 is attached to the surface of the through-type spherical structure 221 for elastic attachment of the through-type spherical structure 221 to the annular spherical surface 211. The space between the reduced-diameter ring 231 and the connector 220 is the deflection angle range of the connector 220.

[0033] Specifically, medical-grade stainless steel can be used to manufacture the conical spring 240 to ensure its long-term elastic performance and biocompatibility. The axial position of the reduced-diameter ring 231 can be adjusted by using a threaded structure to change the spring compression, thereby achieving flexible adjustment of the clamping force and rotational damping. A guide groove is provided on the outer wall of the connecting sleeve 210, and a corresponding protrusion is provided in the reduced-diameter ring 231, which is embedded in the guide groove to achieve axial sliding but circumferential fixation of the reduced-diameter ring 231, preventing the spring from twisting during compression and rebound. The positioning sleeve 230, the reduced-diameter ring 231, and the conical spring 240 are pre-assembled into an independent replaceable module to improve product assembly efficiency and consistency. At the same time, silicone gaskets or a lubricating coating can be added to the spherical mating parts to work in synergy with the conical spring 240 to further optimize the smoothness of rotation and the feel of operation.

[0034] With this configuration, the technical solution establishes a dynamically adaptive elastic limiting structure by incorporating a conical spring 240 and a reducing ring 231 between the positioning sleeve 230 and the connecting sleeve 210. The small end of the conical spring 240 is attached to the surface of the through-type spherical structure 221, while the large end is constrained by the reducing ring 231, creating an inwardly pressing elastic force. This force keeps the spherical structure elastically pressed within the annular spherical surface 211 of the connecting sleeve 210, achieving adaptive contact. When the connector 220 deflects due to changes in body position, the conical spring 240 compresses on the compressed side and releases on the uncompressed side, allowing the ball head to swing freely within the space between the reducing ring 231 and the connector 220. When the external force is removed, the spring's restoring force helps the connector 220 automatically return to center, maintaining stability.

[0035] In one possible implementation, the deflection angle of connector 220 ranges from 20° to 60°.

[0036] In one possible implementation, the outer periphery of the connecting sleeve 210 is provided with multiple anti-slip protrusions 212. This reduces the difficulty of rotating the connecting sleeve 210 and improves the ease of assembly.

[0037] In one possible implementation, the connector 220 also includes a connecting nozzle 222 connected to the through-type spherical structure 221, and the connecting nozzle 222 is inserted into the atomizing cup 300. Thus, the connection and disconnection of the connector 220 and the atomizing cup 300 can be completed simply by plugging and unplugging, improving convenience.

[0038] In one possible implementation, a weight-increasing ring 310 is fitted onto the bottom side of the nebulizer cup 300. Specifically, materials of different densities are selected for the weight-increasing ring 310 according to specific needs, such as metals (stainless steel, copper, etc.), high-density plastics, or composite materials, to achieve ideal weight and cost-effectiveness. The weight-increasing ring 310 on the bottom side of the nebulizer cup 300 primarily adjusts the center of gravity of the entire nebulizer device by increasing the mass of the bottom of the nebulizer cup 300. The design of the weight-increasing ring 310 makes the nebulizer cup 300 more stable during use, especially when the patient's position changes (such as tilting or lying on their side), helping to keep the nebulizer cup 300 nearly vertical, thereby ensuring effective atomization of the medication and reducing residue.

[0039] In one possible implementation, the breathing mask 100 is equipped with straps 110. The main purpose of providing straps 110 to the breathing mask 100 is to ensure that the mask fits securely against the patient's face, thereby guaranteeing effective inhalation of the nebulized mist during treatment. The straps 110 provide the necessary fixation by wrapping around the head, enhancing the seal between the mask and the face, preventing mist leakage and the intrusion of outside air, thus improving the treatment effect.

[0040] In one possible implementation, the pediatric nebulizer also includes a tubing 400 connected to the bottom of the nebulizer cup 300 and a main unit 500 connected to the tubing 400. Specifically, the pediatric nebulizer consists of a main unit 500, tubing 400, nebulizer cup 300, connecting structure 200, and breathing mask 100. The main unit 500 serves as a power source, converting the liquid medication into tiny droplets using compressed air or ultrasound; the tubing 400 guides the airflow into the nebulizer cup 300 and delivers the medication mist; the nebulizer cup 300 contains the liquid medication and completes the nebulization process. The optimized connecting structure 200 ensures efficient delivery of the medication mist. This design achieves efficient drug inhalation, improving therapeutic effects; the integrated structure facilitates assembly and home use; high-quality materials ensure safe and stable operation; and it can be personalized with different accessories to meet the needs of children and long-term care, offering advantages such as ease of operation, safety, reliability, and adaptability.
