Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an atomization adjustment component and an atomizer. Background Technology

[0002] Inhalation nebulizers are important devices for bronchial disinfection and treatment. They work by mixing compressed air from a compressor with atomized medication. The compressed air, carrying the medication, impacts a baffle, breaking down the medication into a fine mist that is delivered to the affected area through a cannula. Because the medication can directly reach the site of infection and is easily absorbed, inhalation nebulizers are crucial for treating respiratory diseases such as bronchitis and asthma.

[0003] The concentration of aerosol generated by existing nebulizers is fixed. However, due to differences in patients' physical condition and the severity of their illness, it is necessary to adjust the concentration according to the patient's actual situation. However, existing mainstream nebulizers cannot be adjusted. In addition, existing adjustable nebulizers control the aerosol concentration by controlling the air intake, but the control structure is difficult to operate and the control accuracy is poor.

[0042] See Figure 1-9 An atomization adjustment component includes a medicine cup 2, a dispersion device, a flow divider base 12, and an atomization cap 1.

[0043] The diversion base 12 is set on the top of the liquid medicine cup 2. A partition block is set in the center of the diversion base 12. An air inlet channel is formed in the partition block. One end of the airflow channel is connected to the atmosphere and the other end is connected to the liquid medicine cup. The dispersing device is connected to the diversion base 12 and is located at the outlet of the airflow channel. A liquid medicine channel is set in the liquid medicine cup. The outlet of the liquid medicine channel is directly opposite the dispersing device.

[0044] The two sides of the partition block form mist outlet channels. One end of the mist outlet channel is connected to the medicine cup, and the other end extends to the top of the diversion base 12. The atomizing cover 1 is sleeved on the diversion base 12. An airflow regulating sleeve 11 is provided between the atomizing cover 1 and the diversion base 12. The rotation of the airflow regulating sleeve 11 can control the air intake of the airflow channel.

[0045] See Figure 4 and 5 In some embodiments, the diversion base 12 is a hollow structure with openings at both ends, and its lower end is detachably connected to the top of the medicine cup. This facilitates the separation of the diversion base 12 from the medicine cup and enables rapid drug addition. In this embodiment, the diversion base 12 and the medicine cup are connected by a snap-fit ​​method.

[0046] The separator 124 is disposed on the upper part of the hollow structure of the diversion base 12. The two ends of the separator 124 are connected to the inner wall of the diversion base 12. The two sides of the separator 124 form a mist outlet channel 122. The two mist outlet channels are symmetrically arranged and communicate with the top of the diversion base. The mist-like medicine is discharged through the mist outlet channel 122.

[0047] The air intake channel is located in the partition block. Both ends of the air intake channel 121 penetrate the sidewall of the diversion base. An air outlet 123 is located at the center of the bottom of the partition block. The air outlet is connected to the air intake channel. External airflow enters through both ends of the air intake channel and enters the nebulizer cup through the air outlet. It mixes with the nebulized drug solution to form a mist-like drug solution airflow. The aerogel concentration in the mist-like drug solution airflow can be controlled by adjusting the air intake volume. For example, if the aerogel concentration needs to be increased, the air intake volume is reduced; if the aerogel concentration needs to be reduced, the air intake volume is increased, so that the mist-like drug solution can be suitable for different patients.

[0048] In some embodiments, a positioning structure and a fixing structure are provided between the atomizing cap and the flow splitter base; the positioning structure is used to position the relative position between the atomizing cap and the flow splitter base, and the fixing structure is used to fix the atomizing cap and the flow splitter base so that the two form an integral structure.

[0049] The atomizing cover is provided with an air inlet hole that matches the air inlet channel. When the atomizing cover and the diverter base are connected, the two ends of the air inlet channel 121 are coaxially connected to the two air inlets on the atomizing cover. The top of the atomizing cover is provided with a mist outlet pipe. The lower end of the mist outlet pipe is connected to the mist outlet channel. The upper end of the mist outlet pipe is used to connect to a breathing device, such as a mask or atomizing nozzle, through a pipe.

[0050] The positioning structure includes a protruding structure and a groove structure. The protruding structure is disposed on the lower side wall of the flow divider base, and the groove structure is disposed on the bottom of the inner wall of the atomizing cover. When the atomizing cover and the flow divider base are connected, the groove structure and the protruding structure are engaged.

[0051] The fixing structure includes an annular groove and a retaining ring. The annular groove is located at the lower part of the outer wall of the flow divider base 12 and forms an inwardly concave annular groove on the outer wall. The retaining ring is located at the bottom of the inner wall of the atomizing cover. When the retaining ring is in the annular groove, the atomizing cover and the flow divider base are connected, and an annular space for installing the airflow regulating sleeve is provided between the atomizing cover and the flow divider base.

[0052] In some embodiments, the airflow regulating sleeve 11 is a sleeve structure with an regulating hole on its side wall and an regulating handle on the edge of the regulating hole. The regulating handle extends outward, i.e. away from the center of the atomizer. The regulating handle is located in the air inlet of the atomizing cover and extends outward. The airflow regulating sleeve 11 is fitted outside the diverter base and can rotate circumferentially. The air intake is controlled by controlling the overlap between the regulating hole and the end of the air intake channel. When the regulating hole and the end of the air intake channel overlap, the air intake reaches the maximum. When the regulating hole and the end of the air intake channel are completely misaligned, i.e., the airflow regulating sleeve covers the air intake channel, the concentration of aerogel in the atomized liquid is adjusted.

[0053] The airflow regulating sleeve has protrusions at both the top and bottom, and the airflow regulating sleeve makes point contact with the atomizing cover and the diverting base to reduce rotational resistance and improve the smoothness of the airflow regulating sleeve's rotation.

[0054] The dispersion device includes a ring 14 and a dispersion column 13. The upper end of the ring is connected to the air outlet of the separator block. A cross-shaped dispersion net 15 is provided in the ring 14. The dispersion column 13 is installed in the center of the dispersion net 15, and the lower end of the dispersion column 13 is directly opposite the outlet of the liquid channel and maintains a certain distance. Under the action of negative pressure airflow, the liquid expands with the dispersion column 13 to form liquid particles, and forms a secondary collision with the dispersion net to form even finer particles.

[0055] In some embodiments, see Figure 7 and 8 The medicine cup is a container with an open top. An airflow column 23 is provided in the center of the medicine cup, and an airflow hole is provided in the center of the airflow column. An air guide tube 4 is provided at the bottom of the medicine cup, and the air guide tube is connected to the airflow hole. The air guide tube 4 is used to connect to an air pump. A dispersion frame 22 is sleeved on the airflow column 23, and multiple medicine channels 22 are formed between the dispersion frame and the airflow column.

[0056] The dispersing frame 21 includes a liquid tube and a support frame. The support frame is a circular frame structure, and the liquid tube is located at the center of the support frame. The liquid tube is used to fit onto the airflow column. Multiple liquid channels are arranged circumferentially inside the liquid tube. When a positive pressure airflow is generated in the airflow column, a negative pressure is formed in the liquid channels. Under the action of the negative pressure, the liquid in the liquid cup flows from bottom to top through the liquid channels. Under the action of the negative pressure, the liquid impacts the dispersing column to form particles. The granular liquid disperses and forms a secondary impact with the dispersing net to form smaller liquid particles and diffuses into the liquid cup. At the same time, it impacts the support frame again and repeats the above impact process until the kinetic energy is lost to form a mist liquid. The mist liquid reacts with the external gas entering through the air inlet to generate an aerosol, which is then input through the mist outlet channel.

[0057] In use, the atomizer main unit is connected to the air guide tube of the medicine cup. The medicine cup is filled with medicine, and compressed air flows out through the airflow column to form a negative pressure effect. Under the action of negative pressure, the medicine and compressed air are mixed. After mixing, the mixture is sprayed onto the dispersion column by the compressed air. Through collision, it becomes micro-droplets and forms mist particles. These mist particles react with the external gas entering through the air inlet to generate an aerosol, which is then input through the mist delivery tube at the top of the atomizer cap.

[0058] Rotate the airflow regulating sleeve according to the patient's condition to control the overlap between the regulating hole and the air intake channel, thereby adjusting the amount of external airflow. When the regulating hole and the air intake channel are fully aligned, the airflow is adjusted to the maximum, and the external air and mist droplets form an aerosol. The aerosol is then inhaled by the patient through the mask at the top of the nebulizer cap.

[0059] Correspondingly, this application also provides a nebulizer, including an inhalation component, a main unit, and the nebulization adjustment component. The upper end of the nebulization adjustment component is connected to the inhalation component via a flexible tube, and the air delivery tube of the medicine cup is connected to the main unit. The inhalation component is a mask or a mouthpiece.

[0060] The atomization adjustment component of this application has the following advantages:

[0061] The nebulizer's distribution base and medication cup are detachably connected, facilitating rapid medication addition and improving ease of use. By incorporating an airflow regulating sleeve and air intake channel, users can easily rotate the sleeve to control the airflow volume, thereby adjusting the aerogel concentration in the nebulized medication. This design meets the treatment needs of different patients, providing a personalized nebulization therapy experience.

[0062] The ring, dispersion column, and dispersion net in the dispersion device work together to disperse the medication through multiple layers of impact and dispersion via the dispersion column, dispersion net, and support frame during its flow. This multi-stage collision and dispersion mechanism forms finer mist particles, improving the atomization effect and efficiency. This design helps the medication be better absorbed by the patient, and the multi-layered design improves the uniformity and fineness of the atomization, which is beneficial for patient absorption and enhances the therapeutic effect.

[0063] The separator design in the splitter base allows the airflow and liquid medicine to enter the atomization area through different channels, reducing airflow interference with the liquid medicine flow and improving the stability and consistency of atomization. External airflow enters the liquid medicine cup through the air intake channel, mixes with the liquid medicine to form a mist-like liquid medicine airflow. This design ensures thorough mixing of airflow and liquid medicine, making the atomization process more uniform and efficient.

[0064] The positioning and fixing structures between the atomizing cap and the distributor base allow for quick, accurate, and secure connection. This design simplifies operation and improves ease of use.

[0065] In summary, this nebulization adjustment component provides an efficient, convenient, and personalized solution for nebulization therapy through its modular design, flexible airflow adjustment, efficient dispersion effect, optimized airflow path, easy-to-operate positioning and fixing structure, multi-level impact and dispersion, good sealing performance, and wide applicability.

[0066] The above content is only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed in this utility model shall fall within the scope of protection of the claims of this utility model.
