Description

Technical Field

[0001] The utility model belongs to the technical field of nasal cavity cleaning, and particularly relates to a nasal cavity cleaning sprayer. Background Art

[0002] As people become more aware of healthy lifestyles, nasal irrigation is gaining increasing attention as an effective method for maintaining respiratory health. Nasal irrigators use atomization technology to convert liquid medication into fine particles for easy inhalation, achieving therapeutic goals such as cleaning the nasal cavity and relieving nasal inflammation.

[0003] Existing nasal cleaning sprayers usually atomize the medicine liquid through an atomizing nozzle to help patients clean their nasal cavity. The design of the atomizing nozzle in the existing technology may not be reasonable enough, resulting in uneven distribution of the medicine liquid during the atomization process, and the atomized particles are of different sizes, affecting the therapeutic effect of the medicine and the comfort of the patient. Due to the uneven atomized particles, some large-particle medicine liquid may not be able to be inhaled, resulting in waste of medicine liquid and reduced drug utilization rate. In some existing technologies, the atomized particles are too large, which may lead to poor inhalation effect and difficulty in fully absorbing the medicine, affecting the therapeutic effect. In the existing technology, after the atomization cleaning of the nasal cavity, the waste liquid is handled by manual wiping, which is not convenient, neither environmentally friendly nor easy to clean.

[0004] In order to solve the above defects of the prior art, a nasal cleaning sprayer is proposed. Utility Model Content

[0005] The present invention aims to solve the technical problem that the above-mentioned existing technology uses an atomizing nozzle to atomize the drug liquid, resulting in uneven distribution of the drug liquid during the atomization process, different sizes of atomized particles, affecting the therapeutic effect of the drug and the comfort of the patient, and making it difficult to collect the waste liquid.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A nasal cleaning sprayer comprising:

[0008] The nebulizer cup is connected to the nebulizer through a catheter. The nebulizer atomizes the liquid medicine in the nebulizer cup, and the nasal wash medicine is inhaled into the nasal cavity through breathing to clean the nasal cavity;

[0009] The atomizer core has its bottom end inserted into and sleeved on the outside of the nozzle inside the atomizer cup, forming a drug delivery channel connected to the drug liquid pool with the nozzle. The top end of the nozzle is connected to the airflow regulating valve on the atomizer core. A baffle for initially screening aerosol particles is provided at the bottom end of the atomizer core and outside the airflow regulating valve.

[0010] The sealing cover is threadedly connected to the atomizer cup and the atomizer core is packaged and positioned in the atomizer cup. The sealing cover is provided with an air intake regulating valve;

[0011] The nose washing head is threadedly connected to the mist outlet of the atomizer cup, and the outer side surface of the nose washing head is threadedly sleeved with a waste liquid cover forming a waste liquid bin therewith.

[0012] Preferably, the liquid medicine pool is a bucket-shaped tank, and the nozzle is arranged through the liquid medicine pool from the center of the liquid medicine pool.

[0013] Preferably, the drug delivery channel forms a plane at the top of the nozzle, and the air flow regulating valve regulates the flow rate of the gas ejected from the nozzle.

[0014] The plane formed by the drug delivery channel helps to evenly distribute the drug solution at the nozzle, thereby avoiding uneven atomization caused by uneven distribution of the drug solution.

[0015] Preferably, the step A at the top of the atomizer core is limited on the limiting ring A on the inner side of the top of the atomizer cup. The limiting design can ensure the correct position of the atomizer core and prevent it from moving or offsetting.

[0016] Preferably, the step B at the top of the sealing cover is positioned on the limiting ring B on the inner side of the top of the atomizer core, and the pressing ring at the bottom of the sealing cover is pressed on the atomizer core. This structure helps to stabilize the relative position of the sealing cover and the atomizer core.

[0017] Preferably, the mist outlet is a horizontal nozzle or an inclined nozzle that tilts upward and outward. The horizontal or inclined design helps to adjust the flow direction of the atomized particles.

[0018] Preferably, the nose wash tip includes a docking portion threadedly sleeved on the outer side of the mist outlet nozzle, an inclined portion connected to the docking portion and inclined upward and outward, and a nose plug that gradually decreases in diameter upward and outward and is inserted into the nasal cavity.

[0019] Preferably, the waste liquid cover is threadedly sleeved on the outer side of the inclined portion, so as to facilitate the collection and cleaning of waste liquid.

[0020] Compared with the prior art, the technical effects and advantages of the utility model are:

[0021] This nasal cleansing sprayer is connected to the nebulizer via an atomizer cup, which uses compressed air to atomize the liquid medicine in the atomizer cup. The liquid medicine is concentrated in a bucket-shaped pool of liquid medicine within the atomizer cup and forms a uniform liquid surface at the nozzle through the drug delivery channel. Compressed air cuts the liquid medicine through the nozzle, forming fine atomized particles. The airflow control valve and baffle work together to adjust the gas flow rate and perform preliminary screening of the atomized particles, ensuring that only sufficiently small atomized particles can be inhaled by the patient through the nasal wash nozzle. This design improves atomization efficiency, makes the liquid medicine more evenly distributed, and the atomized particles are of uniform size, thereby enhancing the therapeutic effect of the drug and patient comfort.

[0022] The sealing cap secures the atomizer core via a threaded connection and features an air intake regulating valve to control airflow. Step A at the top of the atomizer core and step B at the top of the sealing cap are respectively positioned on retaining rings within the atomizer cup, ensuring the correct position of the atomizer core and preventing movement or displacement. The pressure ring ensures a tight seal between the atomizer core and the atomizer cup, preventing drug leakage. This structural design enhances the stability of the atomizer, preventing components from loosening during use due to vibration and other factors, and ensuring a stable and consistent atomization effect.

[0023] The nasal rinse tip is threaded into the mist outlet. Its design, including a docking section, a tilting section, and a nose tip, facilitates more natural insertion into the nasal cavity, ensuring better distribution of atomized particles throughout the nasal cavity. A waste liquid hood and waste liquid reservoir collect waste liquid after use, facilitating cleanup and monitoring of medication consumption. This design improves comfort and effectiveness, reduces patient discomfort, and facilitates waste liquid collection and disposal, contributing to environmental protection and reduced cleaning efforts.

[0024] By simply removing and installing components, patients can conveniently add medication or clean and maintain the nebulizer. Primary and secondary screening of aerosolized particles ensures that only those that meet performance requirements are inhaled by the patient, improving drug utilization. This user-friendly design allows for easy maintenance and use, enhancing product convenience and user satisfaction. The screening mechanism also reduces drug waste and improves the cost-effectiveness of treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The following is combined with Figure 1-4 To further explain this application,

[0032] The embodiment of the present application discloses a nasal cavity cleaning sprayer, comprising an atomizing cup 1, an atomizing core 2, a sealing cover 3 and a nasal cleaning head 5;

[0033] The atomizer cup 1 is connected to the atomizer through a catheter. The atomizer atomizes the liquid medicine in the atomizer cup 1, and the nasal wash medicine is inhaled into the nasal cavity through breathing to clean the nasal cavity.

[0034] The bottom end of the atomizing core 2 is inserted into and sleeved on the outside of the nozzle 11 inside the atomizing cup 1 and forms a drug delivery channel 21 connected to the liquid medicine pool 12 with the nozzle 11. The liquid medicine pool 12 is a bucket-shaped bin, and the nozzle 11 is set through the liquid medicine pool 12 from the center of the liquid medicine pool 12. The bucket-shaped bin design helps to concentrate the liquid medicine and improve the atomization efficiency. The liquid medicine forms a uniform liquid surface around the central nozzle 11, which is conducive to the compressed air cutting to form atomized particles. The nozzle 11 is set through the center, which helps to produce more uniform atomized particles because the flow of the liquid medicine around the nozzle 11 is more stable. The drug delivery channel 21 forms a plane at the top position of the nozzle 11; the formation of a plane by the drug delivery channel 21 helps to evenly distribute the liquid medicine at the nozzle 11, avoiding uneven atomization caused by uneven distribution of the liquid medicine.

[0035] The top of the nozzle 11 connects to the airflow control valve 22 on the atomizer core 2. The airflow control valve 22 adjusts the flow rate of the gas ejected from the nozzle 11. This design helps the airflow control valve 22 more effectively control the gas flow rate, thereby optimizing the atomization effect. A baffle 23 is located at the bottom of the atomizer core 2, outside the airflow control valve 22, for initially screening aerosol particles.

[0036] The sealing cover 3 is threadedly connected to the atomizer cup 1 and the atomizer core 2 is encapsulated and positioned in the atomizer cup 1. An air inlet regulating valve 31 is provided on the sealing cover 3; the step A24 at the top of the atomizer core 2 is limited on the limiting ring A13 on the inner side of the top of the atomizer cup 1. The limiting design can ensure the correct position of the atomizer core 2, prevent it from moving or offset, and ensure the consistency and stability of the atomization effect. The step B32 at the top of the sealing cover 3 is limited on the limiting ring B25 on the inner side of the top of the atomizer core 2, and the pressure ring 33 at the bottom of the sealing cover 3 is pressed on top of the atomizer core 2. This structure helps to stabilize the relative position of the sealing cover 3 and the atomizer core 2, and prevent the components from loosening due to vibration and other reasons during use. The setting of the pressure ring 33 can ensure the sealing between the atomizer core 2 and the atomizer cup 1 and prevent the leakage of the liquid medicine.

[0037] The nasal wash head 5 is threadedly connected to the mist outlet nozzle 4 of the atomizer cup 1, and the outer side of the nasal wash head 5 is threadedly connected to a waste liquid cover 6 that forms a waste liquid bin 7 with it. The mist outlet nozzle 4 is a horizontal nozzle or an inclined nozzle that is inclined upward and outward. The horizontal or inclined design helps to adjust the flow direction of the atomized particles, making it more suitable for the patient to inhale, increasing the comfort and effectiveness of use. The nasal wash head 5 includes a docking portion 51 that is threadedly connected to the outer side of the mist outlet nozzle 4, an inclined portion 52 that is connected to the docking portion 51 and is inclined upward and outward, and a nose plug 53 that is gradually reduced in diameter upward and outward and inserted into the nasal cavity. The threaded docking portion 51 can firmly connect the mist outlet nozzle 4 to ensure the effective transfer of atomized particles. The design of the inclined portion 52 and the nose plug 53 helps the patient insert the nasal cavity more naturally, reduces discomfort, and better distributes the atomized particles throughout the nasal cavity. The waste liquid cover 6 is threadedly connected to the outer side of the inclined portion 52. This design can ensure that the waste liquid cover 6 is tightly coupled with the inclined portion 52, preventing leakage of waste liquid, while facilitating the collection and cleaning of waste liquid.

[0038] In this nasal cleaning sprayer, the atomizer acts as a compression host to provide high-flow compressed air, which enters the atomizer cup 1. The surface of the medicine liquid is cut by the structure of the atomizer cup 1 to form atomized particles. Only the atomized particles that meet the performance requirements can pass through the nasal washing head 5 and be inhaled by the patient.

[0039] The specific process of atomizing the drug solution is as follows: remove the nasal wash tip 5 and the atomizer core 2; add the drug solution to the drug solution pool 12 through the mouth of the atomizer cup 1, and from the drug solution pool 12, pass through the drug delivery channel 21 to form a plane at the nozzle 11; the atomizer outputs compressed air, which is transferred to the drug solution plane through the nozzle 11 in the atomizer cup 1; finally, the drug solution is cut into atomized particles by the compressed air at the top of the nozzle 11; the airflow regulating valve 22 adjusts the gas flow rate ejected from the nozzle 11 so that it is not too large, resulting in large atomized particles being transported to the inhalation channel; the baffle 23 blocks the airflow, preventing it from directly entering the inhalation channel of the nasal wash tip 5 and requiring it to pass through the baffle 23 for screening; the baffle 23's preliminary screening of the atomized particles can effectively prevent large particles of drug solution from being inhaled, as these large particles may irritate the nasal cavity, cause discomfort, or fail to effectively clean the nasal cavity. The preliminary screening ensures that only sufficiently small atomized particles are inhaled, thereby improving the therapeutic effect of the drug and the comfort of the patient.

[0040] The baffle 23 performs a preliminary screening on the formed atomized particles. Oversized atomized particles are blocked by the baffle 23 and fall back into the medicine pool 12. Atomized particles that are small enough rise to the upper part of the atomizing cup 1 with the airflow. As the patient inhales, the airflow into the atomizing cup 1 will screen the atomized particles. Only atomized particles that meet the standards can enter the mist outlet 4 and be inhaled by the patient through the nasal wash head 5. Atomized particles that fail to meet the standards fall back into the medicine pool 12 and are cut, processed and screened again. Since the atomized particles are screened, unqualified particles will fall back into the medicine pool 12, which can ensure that the medicine is fully atomized, reduce waste, and improve drug utilization. The setting of the airflow regulating valve 22 can adjust the gas flow rate to avoid the atomized particles being too large due to too fast a flow rate, thereby affecting the inhalation effect and drug absorption.

[0041] The nasal wash head 5 is equipped with a waste liquid cover 6 and a waste liquid reservoir 7. Waste liquid from the nasal wash flows along the waste liquid cover 6 and is collected in the waste liquid reservoir 7. This arrangement collects the waste liquid after use, preventing it from being directly discharged into the environment. This is both environmentally friendly and reduces the need for cleanup. Waste liquid collection also facilitates monitoring of drug consumption and atomization results. By simply removing and installing components, patients can conveniently add medication or clean and maintain the sprayer, enhancing the product's ease of use.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
