Description

Technical Field

[0001] This utility model relates to a medical auxiliary material, specifically, to an airflow nebulizer with adjustable flow rate. Background Technology

[0002] Medical nebulizers are mainly used to treat various upper and lower respiratory system diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis, and other diseases occurring in the trachea, bronchi, alveoli, and pleural cavity. Nebulized inhalation therapy is an important and effective treatment method for respiratory diseases. A nebulizer atomizes medication into tiny particles, which are then inhaled and deposited in the respiratory tract and lungs, achieving painless, rapid, and effective treatment. Currently, there are many medical nebulizers on the market, such as those disclosed in Chinese patents CN209316733U, CN219558346U, and CN212282430U. During use, the nebulization rate and drug delivery speed are adjusted by regulating the airflow. This often requires the patient to raise their arm and hold the nebulizer high near their mouth and nose, which can cause significant discomfort.

[0003] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an airflow atomizer with adjustable flow rate.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An adjustable flow rate nebulizer includes a cup body, a cup lid, a cup core, and a flow regulation structure. The lower end of the cup body has a pipe interface connected to an air compressor via an air supply pipe. The side of the cup body has a nebulization outlet connected to a nebulization connecting tube, which in turn connects to a breathing mask. The breathing mask's contour conforms to the contours of the mouth and nose. Elastic bands are provided on both sides of the breathing mask, and a drug delivery interface is located on the outer side of the mask. The end of the nebulization connecting tube near the cup body is cylindrical, while the end away from the cup body is rectangular. The inner wall of the rectangular end is also cylindrical and has internal threads. The drug delivery interface has external threads, and the drug delivery interface is threadedly connected to the nebulization connecting tube.

[0006] The lower end of the cup body is detachably connected to the upper end of the support rod. The support rod is telescopic and has a grip at its lower end.

[0007] The lower end of the cup body is provided with several positioning grooves. The positioning grooves are arc-shaped and coaxial with the cup body. Two parallel limiting support plates are provided on the lower side of the positioning grooves. There is a gap between the two limiting support plates. There is a notch between one end of the limiting support plate and the end of the positioning groove. The upper end of the support rod is provided with a connecting seat. The upper end of the connecting seat is provided with a positioning pin corresponding to the positioning groove. The top of the positioning pin is provided with a limiting block. The outer diameter of the positioning pin is adapted to the gap between the two limiting support plates. The outer contour of the limiting block is adapted to the notch.

[0008] The lower end of the connector is provided with a connecting groove, and the upper end of the support rod is provided with an external thread. The lower end of the connector is threadedly connected to the upper end of the support rod.

[0009] The outer contour of the connector is adapted to the outer contour of the cup body. The top of the connector is provided with an open receiving groove, and the side of the receiving groove is provided with a U-shaped opening. The upper end of the U-shaped opening is connected to the upper end of the connector, and the gas supply pipe passes through the U-shaped opening to connect to the cup body.

[0010] Compared to existing technologies, this invention offers several advantages. It provides a nebulizer with adjustable flow rate, featuring a scientific design and ease of use. During prolonged nebulization, the patient's arm does not need to be held high for extended periods, making the nebulization process more convenient. In practical use, for short-duration nebulization, the rectangular end can be placed directly into the mouth and bit down, or the rectangular end can be threaded onto a breathing mask, which is then fastened over the mouth and nose, with the elastic band hooked to the ears for simple positioning. For longer nebulization sessions, an air compressor can be connected via an air supply pipe, followed by connecting the connector and cup body, and then connecting the support rod and connector. The height of the support rod can be adjusted as needed before nebulization. During nebulization, the patient can hold the lower end of the support rod or another comfortable position, eliminating the need to hold their arm up for extended periods.
