Description

Technical Field

[0001] This utility model relates to the medical field of medical nebulizers, specifically to an improved nebulizer core and a medical nebulizer made based on the nebulizer core. Background Technology

[0002] Medical nebulizers atomize liquid medication into tiny particles, which are then inhaled and deposited in the respiratory tract and lungs, achieving painless, rapid, and effective treatment. They are classified as Class II medical devices. Clinically used medical nebulizers generally include a mouthpiece (or mask), a nebulizer container, and a nebulizer core housed within the container.

[0003] Reference manual attached Figure 5 Existing nebulizer cores generally include a base 1 and a conical column 2 integrally connected to the base 1. The base 1 has a downwardly extending convex edge 11 at its bottom periphery, and the convex edge 11 is provided with multiple capillary ports 12 arranged in a ring. The nebulizer core is assembled in the nebulizer canister, and the medication is prepared and poured into the nebulizer canister. The nebulizer is then connected to the nebulizer pump through the air delivery tube. The patient holds the mouthpiece (or uses a face mask), and the nebulizer pump is turned on. High-pressure gas enters the nebulizer core in the nebulizer through the air delivery tube, and negative pressure is generated at the multiple capillary ports, drawing the medication out from the adjacent capillary ports. At the same time, the medication is impacted by the high-speed airflow at the capillary ports, forming fine droplets. The droplets generated in the nebulizer canister are sprayed into the patient's mouth or nose through the mouthpiece (or face mask). The existing nebulizer core design results in less than ideal nebulization effects, with insufficient ability to transform the medication into tiny droplets per unit time, leading to low nebulization efficiency. Furthermore, during use, as the medication in the nebulizer canister decreases, tilting the canister at an angle (e.g., 60°, 90°) exposes part of the capillary tube opening on the base of the canister to the medication, reducing or even eliminating the ability to convert the medication into aerosol, thus affecting the nebulizer's usability. For patients unable to cooperate with nebulization in a sitting or semi-recumbent position (such as infants, restless patients, or those requiring a strictly supine position), the medication in the canister cannot be effectively released, thus impacting the treatment outcome. Utility Model Content

[0004] This utility model provides an improved nebulizer core and a medical nebulizer made based on the nebulizer core. Its purpose is to overcome the shortcomings of existing nebulizer cores, such as imperfect structural design, low nebulization efficiency, and reduced ability of the liquid medicine in the nebulizer to be converted into aerosol when the nebulizer is tilted at a certain angle, which affects the use of the medical nebulizer.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] An improved atomizing core, a base, and a conical column integrally connected to the base, the base having a downwardly extending convex edge at its bottom periphery, and the convex edge having a plurality of capillary orifices arranged in a ring; it also includes a sleeve adapted to (i.e., in contact with) the inner wall of the atomizing can, the bottom of the sleeve being fixedly connected to the base, and the side wall of the sleeve having a plurality of aerosol holes penetrating through it.

[0007] Furthermore, the shroud is a conical cylinder with a larger opening at the top and a smaller opening at the bottom, and the height of the conical cylinder is lower than the height of the conical column.

[0008] Furthermore, the plurality of aerosol holes are evenly distributed on the side wall of the casing, and the diameter of each aerosol hole is 0.8mm-1.2mm.

[0009] Furthermore, the enclosure is a plastic enclosure, and multiple aerosol holes are formed by drilling holes in the side wall of the plastic enclosure using a thread.

[0010] Furthermore, the atomizing core is assembled inside the atomizing can, and its surrounding sleeve is in contact with the inner wall of the atomizing can.

[0011] An improved medical nebulizer made of a nebulizer core includes a mouthpiece and a nebulizer canister, and also includes a nebulizer core installed inside the nebulizer canister, the nebulizer core being fitted with a sleeve on it that fits against the inner wall of the nebulizer canister.

[0012] As described above, compared with the prior art, the advantages of this utility model are as follows: The nebulizer core and medical nebulizer have an ideal structural design, employing multiple capillary openings combined with multiple aerosol holes, resulting in ideal nebulization effect and enhanced ability of the medication to transform into tiny droplets per unit time, leading to high nebulization efficiency. Furthermore, during use, as the medication in the nebulizer canister decreases, if the canister is tilted at a certain angle (e.g., 60°, 90°), the presence of multiple aerosol holes on the side wall of the canister minimizes the impact on the medication's ability to be converted into aerosol, thus expanding the nebulizer's application scenarios. For example, even for patients unable to cooperate with nebulization in a sitting or semi-recumbent position (such as infants, restless patients requiring a strict supine position), the medication in the canister can be effectively released. Nebulization can be performed in various positions, improving the therapeutic effect. It also effectively avoids the problem of nebulization pausing due to tilting of the medication cup during nebulization; improves the accuracy of drug administration, increases patient satisfaction, and enhances the work efficiency of medical staff.

[0020] See attached document Figure 1 and Figure 2 The surrounding cylinder 3 is a conical cylinder with a wider upper opening and a narrower lower opening, and the height of this conical cylinder is lower than the height of the conical column 2. The plurality of aerosol holes 30 are evenly distributed on the sidewall of the surrounding cylinder 3, and the diameter of each aerosol hole 30 is 0.8mm-1.2mm (e.g., 0.8mm, 1mm, or 1.2mm). The surrounding cylinder 3 is a plastic cylinder, and the sidewall of the plastic cylinder is drilled using a tool (e.g., a needle) to form the plurality of aerosol holes 30.

[0021] See attached document Figure 1 , Figure 2 , Figure 3 and Figure 4An improved medical nebulizer with an atomizing core includes a mouthpiece 4 and a nebulizer canister 2, and the aforementioned atomizing core installed inside the nebulizer canister 2. The atomizing core is fitted inside the nebulizer canister 2, and its surrounding sleeve 3 is in contact with the inner wall of the nebulizer canister 2. The atomizing core is installed inside the nebulizer canister, and the medication is prepared and poured into the nebulizer. The nebulizer is then connected to a nebulizer pump via an air delivery tube. The patient holds the mouthpiece in their mouth, and the nebulizer pump is turned on. High-pressure gas enters the atomizing core in the nebulizer through the air delivery tube, and negative pressure is generated at multiple capillary openings and multiple aerosol holes 30, drawing the medication out from the adjacent capillary openings and aerosol holes 30. Simultaneously, the medication is impacted by the high-speed airflow from the capillary openings and aerosol holes 30, forming fine droplets. The droplets generated inside the nebulizer canister are sprayed into the patient's mouth or nose through the mouthpiece. The ability of the medication to be transformed into tiny droplets per unit time is enhanced, resulting in high nebulization efficiency.

Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
