Technical Field
[0001] This utility model relates to the technical field of nasal inserts, and in particular to a nebulizing nasal insert. Background Technology
[0002] A nasal nebulizer is a medical device used to treat respiratory diseases. It delivers medication to the lungs via nebulization through the nasal cavity and is suitable for patients with asthma, chronic obstructive pulmonary disease, and other respiratory conditions. Its design conforms to the nasal cavity structure, ensuring efficient drug delivery, and it is both comfortable and portable, making it suitable for home and clinical use. However, the connection structure between the tube and the nasal plug directly affects the treatment effect. Traditional connection methods suffer from poor sealing, allowing medication to leak from the connection between the nasal plug and the tube, resulting in low medication utilization efficiency, wasted medication, and reduced treatment effectiveness. Furthermore... The existing connecting tube structure fails to fully consider the hydrodynamic characteristics and physiological structure of the nasal cavity. The flow rate of the medication during delivery is too fast and turbulence is easily generated. This not only makes it impossible to accurately reach the nasal mucosa, but also causes medication loss due to splashing. At the same time, most nasal plug designs do not effectively separate and guide the two nasal cavities, resulting in the medication not being delivered evenly to both nasal cavities. This not only reduces the drug absorption efficiency, but may also cause discomfort or even damage to the nasal mucosa due to excessively high local drug concentration. It is difficult to meet the requirements of safe, efficient and comfortable nebulization therapy. Therefore, the above problems need to be improved. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Example: See Figure 1-4This utility model discloses a nasal plug for nebulization, comprising a nasal plug 1. One end of the nasal plug 1 has an annular sealing groove, one side of which abuts against a limiting ring. The other end of the nasal plug 1 is equipped with a guide assembly. A connecting tube 2 is installed on one side of the nasal plug 1, one end of which is placed inside the nasal plug 1, and the outer side of the connecting tube 2 abuts against the inner wall of the nasal plug 1. The connecting tube 2 is L-shaped, and the other end of the connecting tube 2 is enlarged, facilitating the connection of the nasal plug 1 to a drug delivery tube. The L-shaped bend of the connecting tube 2 forms a flow channel; when the liquid medication enters the enlarged end from the drug delivery tube, the flow velocity decreases due to the increased diameter, reducing turbulence and allowing the liquid medication to smoothly enter the nasal plug 1. A guide tube 5 communicates with the interior of the connecting tube 2, and its opening is inclined at 15°-30° towards the inside of the nasal cavity. ° (conforming to the physiological angle of the nasal cavity), utilizing fluid inertia to directly guide the medication to the nasal mucosa surface, reducing splashing and loss of the medication at the nasal entrance; the guiding component includes an arc-shaped connecting plate fixed to the other end of the nasal plug 1, with mounting grooves at both ends of one side of the arc-shaped connecting plate, and a connecting shell connected to the mounting groove, on which a guiding tube 5 is installed, the guiding tube 5 being internally connected to the connecting tube 2; both the nasal plug 1 and the guiding tube 5 are made of medical-grade rubber, and the guiding tube 5 facilitates the introduction of the medication into the nasal cavity, reducing loss during medication use; the tilt angle of the guiding tube 5 and the separating effect of the separating block 3 allow the medication to be evenly sprayed onto the nasal mucosa at a flow rate of ≤5m / s (measured data), and the atomized particles (5-10μm) form effective deposits in the nasal hair filtration area and the mucosal adsorption area.
[0015] In this novel experimental design, a separation block 3 is installed on the other side of the arc-shaped connecting plate. The separation block 3 is I-shaped and separates the two mounting slots. The separation block 3 facilitates the separation and delivery of the drug solution to the two nasal cavities. A limiting ring is fixed to the connecting tube 2, and a sealing ring 4 is fixed to one end of the limiting ring. The sealing ring 4 has a T-shaped cross-section, and one end of the sealing ring 4 is placed in an annular sealing groove. The annular sealing groove and the sealing ring 4 help prevent the drug solution from leaking from the connection point. The mating surface of the sealing ring 4 and the annular sealing groove bears the axial pressure, and the limiting ring provides the reaction force, forming a rigid sealing structure. This ensures that the guide tube 5 opening maintains an optimal drug delivery distance of 0.5 to 1 cm from the nostril, avoiding mucosal irritation caused by being too close or drug dispersion caused by being too far.
[0016] Working principle: When using this nebulizer nasal insert, first install the components by fitting the nasal plug 1 onto the connecting tube 2. The sealing ring 4 (T-shaped section) at one end of the limiting ring fixed to the connecting tube 2 will be placed in the annular sealing groove opened at one end of the nasal plug 1. The two fit tightly together to form a rigid sealing structure, thereby preventing the liquid from leaking from the connection. The mating surface of the sealing ring 4 and the annular sealing groove bears the axial pressure, and the limiting ring provides the reaction force to ensure the sealing effect. Next, fix the device to ensure that the guide tube 5 opening is kept at the optimal drug delivery distance of 0.5 to 1 cm from the nostril. This can avoid irritation to the nasal mucosa due to being too close and prevent drug loss due to being too far. After completing the preparations, the medication infusion begins. The medication enters the connecting tube 2 from the infusion tube. Because the connecting tube 2 is L-shaped with an expanded diameter at the other end, its L-shaped bend design forms a flow channel. When the medication enters the expanded end, the flow velocity decreases due to the increased diameter, reducing turbulence and allowing the medication to smoothly enter the nasal plug 1. Inside the nasal plug 1, the medication is guided into the nasal cavity through the guide tube 5, which connects to the inside of the connecting tube 2. The guide tube 5 is tilted 15°-30° towards the inside of the nasal cavity (consistent with the physiological angle of the nasal cavity), utilizing fluid inertia to directly guide the medication. The device targets the nasal mucosa surface, reducing splashing and loss of medication at the nasal inlet. Simultaneously, the separating block 3 (Type I) on the nasal plug 1 separates the mounting slots of the two guide tubes 5, allowing the medication to be separately delivered to both nasal cavities. Under the tilt angle of the guide tubes 5 and the separation effect of the separating block 3, the medication is uniformly sprayed onto the nasal mucosa at a flow rate of ≤5m / s. The atomized particles (5-10μm) form effective deposits in the nasal hair filtration area and the mucosal adsorption area, achieving efficient drug delivery and absorption. When the device needs to be replaced after use, it can be removed.
[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
