Description

Technical Field

[0001] This utility model relates to the field of composite flooring technology, specifically to a high-efficiency atomizing medical nebulizer device. Background Technology

[0002] In the field of respiratory medicine, medical nebulizers, also known as medical ultrasonic nebulizers, are a common medical device. They are often used to treat respiratory diseases such as asthma and chronic obstructive pulmonary disease. By atomizing drugs into tiny particles, medical ultrasonic nebulizers can deliver drugs directly to the patient's respiratory tract, improving drug absorption and reducing side effects. When in use, they mainly consist of three parts: the nebulizer unit, the nebulizer cup, and the nebulizer tube.

[0003] Current medical nebulizer devices primarily use compressed gas through a venturi tube to convert the injected medication into atomized particles, achieving nebulization therapy. However, considering that the medication remains stationary inside the nebulizer, the medication containing sediment can easily accumulate at the bottom of the chamber, affecting the nebulization effect and significantly reducing the device's efficiency. Therefore, to address these issues, a high-efficiency nebulizer device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency atomizing medical nebulizer device to solve the problem mentioned in the background art that the efficiency of actual atomization is affected by the deposition of drug solution precipitates during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency atomizing medical nebulizer device includes an atomizing cup body, a base plate fixedly connected to the bottom of the atomizing cup body, a venturi tube body with a through-hole in the middle of the base plate, a short connecting tube connected to the bottom of the venturi tube body, a gasket sleeved on the outside of the short connecting tube, an outer retaining ring glued to the outside of the gasket, double sealing sleeves snapped into pre-drilled holes on the left and right sides of the base plate, a miniature ultrasonic transducer fixedly installed in a pre-drilled groove near the inner ring of the outer retaining ring, an ultrasonic vibrating rod penetrating the double sealing sleeve electrically connected to the top of the miniature ultrasonic transducer, a lightweight collar sleeved on the outside of the ultrasonic vibrating rod, an auxiliary inclined rod fixedly connected to the inner ring surface of the lightweight collar, and a limiting ring fixedly connected to the top of the outer retaining ring and detachably bolted to the atomizing cup body.

[0007] Preferably, an atomizing interface is connected to the upper left position of the atomizing cup body, and an atomizing mask is sealed to the upper left position of the atomizing cup body. The atomizing interface is set at an angle upward.

[0008] Preferably, an atomizing plug is fitted inside the upper part of the atomizing cup body, and the lower end of the atomizing plug is provided with a conical baffle component that is sleeved on the outside of the venturi tube body.

[0009] Preferably, the bottom of the short connecting pipe is connected to a delivery air pipe body, and the end of the delivery air pipe body is connected to an atomizing compressor host.

[0010] Preferably, the limiting ring and the outer retaining ring are coaxially arranged, the surface of the lightweight collar has a circular hole groove structure that engages with the ultrasonic vibrating rod, and several auxiliary inclined rods are inclined downwards and arranged in the drug cavity space formed between the atomizing cup body and the venturi tube body. There are a total of 2 ultrasonic vibrating rods, and rubber ring components are bonded to both the inner and outer surfaces of the double sealing sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the inclusion of an outer retaining ring, a miniature ultrasonic transducer, a gasket, a double sealing sleeve, an ultrasonic vibrating rod, a lightweight collar, an auxiliary inclined rod, and a limiting ring facilitates the efficient atomizing medical nebulizer device. This allows the device to convert the liquid medication inside the nebulizer cavity into atomized particles through the compression of the airflow entering the nebulizer cup and the cooperation of the venturi tube. With the assistance of a short connecting pipe, the ultrasonic vibration structure, composed of the outer retaining ring, miniature ultrasonic transducer, gasket, double sealing sleeve, ultrasonic vibrating rod, lightweight collar, auxiliary inclined rod, and limiting ring, mixes and shakes the liquid medication containing deposits. This prevents the deposits from consistently settling at the bottom of the nebulizer cavity during atomization, which would significantly affect the atomization effect during normal use. Simultaneously, it relatively improves the atomization efficiency of the device during actual use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution:

[0021] A high-efficiency atomizing medical nebulizer device includes an atomizing cup body 1, a base plate 4 fixedly connected to the bottom of the atomizing cup body 1, a venturi tube body 17 connected to the middle of the base plate 4, a short tube 2 connected to the bottom of the venturi tube body 17, a gasket 6 sleeved on the outside of the short tube 2, an outer retaining ring 3 glued to the outside of the gasket 6, double sealing sleeves 7 being snapped into the pre-drilled holes on the left and right sides of the base plate 4, a miniature ultrasonic transducer 5 being fixedly installed in the pre-drilled groove near the inner ring of the outer retaining ring 3, an ultrasonic vibrating rod 8 penetrating the double sealing sleeve 7 being electrically connected to the top of the miniature ultrasonic transducer 5, a lightweight collar 9 being sleeved on the outside of the ultrasonic vibrating rod 8, an auxiliary inclined rod 10 being fixedly connected to the inner ring surface of the lightweight collar 9, and a limiting ring 11 being fixedly connected to the top of the outer retaining ring 3 and detachably bolted to the atomizing cup body 1.

[0022] like Figure 1As shown, an atomizing interface 13 is connected to the upper left of the atomizing cup body 1, and an atomizing mask 14 is sealed to the upper left of the atomizing cup body 1. The atomizing interface 13 is set at an upward angle. This structural design is ergonomic and makes the whole device more convenient to use. An atomizing plug 12 is installed inside the upper part of the atomizing cup body 1. The lower end of the atomizing plug 12 is provided with a conical baffle component that is sleeved on the outside of the venturi tube body 17. The conical baffle is mainly used to initially screen atomized particles, block large particles from atomizing, and prevent exhaust gas backflow. The bottom of the short pipe 2 is connected to the air delivery pipe body 15, and the end of the air delivery pipe body 15 is connected to the atomizing compressor host 16. With the connection between them, it is convenient for compressed air to be sent into the interior of the atomizing cup body 1.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the limiting ring 11 and the outer retaining ring 3 are coaxially arranged. The surface of the lightweight collar 9 has a circular hole groove structure that engages with the ultrasonic vibrating rod 8. Several auxiliary inclined rods 10 are inclined downwards and arranged in the drug cavity space formed between the atomizing cup body 1 and the venturi tube body 17. There are two ultrasonic vibrating rods 8. The inner and outer surfaces of the double sealing sleeve 7 are bonded with rubber ring components. When the ultrasonic vibrating rod 8 is running, the double sealing sleeve 7 can effectively seal the ultrasonic vibrating rod 8 inserted into the drug cavity by using its inner and outer bonded rubber ring components to prevent the drug liquid from flowing downwards.

[0024] Workflow: The nebulizer device in this invention requires an external power source for startup. Before using the medical nebulizer device, it is necessary to ensure that the first and last ends of the delivery tube 15 are tightly connected to the outlet port of the nebulizer compressor 16 and the inlet port of the short tube 2. When using the medical nebulizer device to treat patients with respiratory diseases, open the top cover of the nebulizer cup 1, pour an appropriate amount of medication into the medication chamber formed between the venturi tube 17 and the base 4, then insert the nebulizer plug 12 into the nebulizer cup 1. The conical baffle at the bottom of the nebulizer plug 12 will be engaged by the venturi tube 17. Then, close the top cover again to seal the inside of the nebulizer cup 1. Next, start the entire device and cover the patient's mouth and nose with the nebulizer mask 14. The compressed airflow generated inside the nebulizer compressor 16 will pass through the inside of the delivery tube 15 and be delivered sequentially into the patient's mouth and nose. The short tube 2, the venturi tube body 17, and the nebulizer plug 12 convert the liquid medicine inside the medicine chamber into atomized particles. These atomized particles are delivered into the patient's mouth and nose through the nebulizer interface 13 and the nebulizer mask 14 to achieve the purpose of nebulization therapy. Since the outer retaining ring 3 is sleeved on the outside of the short tube 2 and the limiting ring 11 is fixed to the outside of the nebulizer cup body 1 by bolts, the two ultrasonic vibrating rods 8 on the left and right will fit into the inside of the medicine chamber. Before inserting the nebulizer plug 12, the lightweight collar 9 is placed into the medicine chamber and locked together with the two ultrasonic vibrating rods 8. During the subsequent conversion of the liquid medicine into atomized particles, the two miniature ultrasonic transducers 5 in the activated state will emit ultrasonic waves. The device can use the ultrasonic vibrating rods 8, the lightweight collar 9, and multiple auxiliary inclined rods 10 to vibrate, mix, and shake the liquid medicine pre-injected into the medicine chamber to prevent the sediment in the liquid medicine from settling at the bottom of the medicine chamber and affecting the nebulization effect.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
