Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical equipment, and more specifically, to an atomization inhalation auxiliary device. Background Art
[0002] Nebulizer is a commonly used medical device for aerosol treatment of patients with respiratory diseases. Liquid medicine is converted into gas by ultrasound or heating, and sent into the patient's respiratory tract to treat some respiratory diseases. The nebulizer is mainly composed of a drug atomization device and a mask or oral tube, which are suitable for different groups of people. Among them, the drug atomization device converts the liquid medicine into gas by ultrasound or low-temperature heating, and then sends it into the mask or oral tube through a tube. While ensuring airtightness, the patient can inhale the gas medicine into the respiratory tract through breathing, which has a therapeutic effect on some respiratory diseases. The nebulizer is usually also provided with an air outlet for discharging the patient's exhaled gas. During the aerosol inhalation treatment, the patient needs to take a deep breath with his mouth and inhale the drug aerosol deep into the lungs to ensure the treatment effect. However, this nebulizer has the following problems:
[0003] Nebulizers lack interest: Current nebulizer designs often focus on functionality, while neglecting their psychological acceptance among pediatric patients. Young children often lack interest in traditional, monotonous nebulizer treatment devices, resulting in low treatment compliance.
[0004] Limitations of the air inlet and outlet: The air inlet and outlet are in the same direction, which may cause difficulty for patients to master the inhalation technique. Even if medical staff repeatedly teach that they should take a deep breath through their mouths to inhale the mist into the lungs during treatment, some patients still find it difficult to master the technique;
[0005] The treatment process is boring: The nebulization treatment lasts about 10-20 minutes. The nebulization treatment is long and the process is relatively boring, which can easily cause the patient to be distracted and breathe through the nose instead of taking a deep breath through the mouth. The drug aerosol cannot reach the deep lungs, thus affecting the treatment effect;
[0006] Low drug inhalation rate: When patients are unable to effectively inhale drug aerosols deep into the lungs, it will only result in waste of drug aerosols. Utility Model Content
[0007] The present invention aims to overcome at least one defect of the above-mentioned prior art and provide an atomization inhalation auxiliary device for solving the problems that the nebulizer lacks interest, the air inlet and outlet are in the same direction, the treatment process is boring and the drug inhalation rate is low.
[0008] The technical solution adopted by the utility model is an atomization inhalation auxiliary device, which includes a tube body and an oral tube. One end of the oral tube is connected to the tube body, and the other end of the oral tube is used to contact the patient's mouth. The tube body is hollow inside, and a through hole is opened on the top of the tube body. An observation device is provided in the middle of the through hole.
[0009] When the patient inhales, the vaporized medicine liquid continuously flows into the tube body through the through-hole and enters the patient's body through the mouth. The patient and medical staff can intuitively observe the exact situation of the medicine aerosol being inhaled into the patient's lungs through the observation device in the through-hole, which improves the efficiency and accuracy of drug inhalation and ensures that every drop of precious medicine can be accurately delivered to the lesion, thereby accelerating the treatment process and improving the treatment effect.
[0010] In order to reduce the loss of drug aerosol and reduce the waste of drug aerosol, the nebulizer inhalation assist device also includes a one-way valve, which is connected to the other end of the tube body and remains closed in a static state. The one-way valve can reduce the unnecessary loss of drug aerosol during transmission, thereby reducing the waste of liquid medicine and ensuring that every drop of medicine can play its maximum therapeutic effect. The one-way valve forms a seamless connection with the tube body, which ensures the smooth flow of air and prevents the loss of drug aerosol. When the device is in a static state, the one-way valve will automatically remain closed, effectively preventing outside air or the patient's exhaled gas from entering the device, avoiding the reverse flow and contamination of the drug aerosol, maintaining the purity and activity of the drug aerosol, and ensuring the cleanliness and hygiene of the inside of the device, providing patients with a safer and more reliable treatment environment.
[0011] In order to make the treatment process more pleasant, interactive and easy to monitor, the observation device is designed as a windmill. The windmill includes multiple blades with mixed colors. When young patients inhale drug aerosols, the windmill can enhance the patients' treatment experience and sense of participation. It also incorporates an observation function, which makes it easier for medical staff and patients to intuitively understand the treatment progress.
[0012] To provide a more intuitive understanding of the treatment process, the fan blades are alternating between yellow and blue. When the patient inhales, the windmill rotates with the airflow. When the airflow velocity reaches a level that allows the patient to inhale the drug aerosol into the lungs, the fan blades turn green. This design not only increases the fun of treatment, making the originally boring treatment process lively and interesting, but more importantly, it also provides medical staff with an intuitive observation window. By observing the windmill's rotation speed and color change, medical staff can indirectly assess the stability of the treatment environment, the distribution of the airflow, and the patient's respiratory status, so as to adjust the treatment plan in a timely manner to ensure maximum treatment effect.
[0013] To provide a more intuitive understanding of the treatment process, the fan blades can be alternating between red and blue. When the patient inhales, the windmill rotates with the airflow. When the airflow velocity reaches a level that allows the patient to inhale the drug aerosol into the lungs, the fan blades turn purple. This design not only increases the fun of the treatment, making the originally boring treatment process lively and interesting, but more importantly, it also provides medical staff with an intuitive observation window. By observing the windmill's rotation speed and color change, medical staff can indirectly assess the stability of the treatment environment, the distribution of the airflow, and the patient's respiratory status, so as to adjust the treatment plan in a timely manner to ensure maximum treatment effect.
[0014] To ensure a secure and leak-tight connection between the check valve and the other end of the tube, a groove is defined at the connection between the tube and the check valve. The connection end of the check valve, connected to the tube, features an elastic rim that engages within the groove. The shape and dimensions of this groove are tailored to the specific location of the check valve, and its depth and width are optimized to provide ample space for the check valve's mounting structure, thereby enhancing the stability of the connection. Furthermore, the elastic rim is made of a highly elastic, wear-resistant material with excellent flexibility and resilience, allowing it to closely conform to the contours of the tube groove. When the check valve is installed on the tube, the elastic rim naturally expands and engages within the groove, forming a tight, virtually leak-proof seal. This not only simplifies installation and allows the check valve to be easily and quickly secured to the tube, but also effectively prevents fluid leakage during fluid transfer through the tight fit between the elastic rim and the groove, ensuring the overall sealing and reliability of the device. In addition, the presence of the elastic outer edge can absorb and relieve stress caused by fluid pressure changes or vibrations to a certain extent, protect the connection parts from damage, and extend the service life of the device.
[0015] In order to improve the flow rate of drug aerosol and the comfort of patient use, the oral tube is funnel-shaped. The wide mouth of the oral tube is connected to the tube body, and the narrow mouth of the oral tube is used to contact the patient's mouth. It utilizes the principle that the air flow rate increases when it flows from an open area to a narrow area, thereby improving the patient's drug inhalation rate.
[0016] To reduce medical costs while ensuring device hygiene standards and safe reuse, this nebulizer inhalation assist device is designed to withstand high-temperature sterilization. The tube, oral tube, and one-way valve are constructed from heat-resistant materials. These materials not only maintain structural stability in high-temperature environments, effectively resisting thermal stress and deformation, but also exhibit excellent chemical stability, preventing adverse reactions with disinfectants during the sterilization process and ensuring the device's long-term performance. Furthermore, the tube, oral tube, and one-way valve are removable and removable, facilitating quick assembly and disassembly for healthcare professionals based on their specific needs and significantly improving cleaning and maintenance. When the device requires cleaning, the individual components can be separated to thoroughly remove any dirt, residual medication, or microorganisms that may have accumulated during use, achieving a deeper cleaning effect and ensuring that the device meets medical-grade hygiene standards before each use. Furthermore, the removable design facilitates individual component replacement. If a component becomes worn or damaged, only the corresponding component can be replaced, rather than the entire device, further reducing maintenance costs. This design not only demonstrates efficient resource utilization but also aligns with current sustainable environmental principles.
[0017] In order to fit the movement trajectory of the windmill as closely as possible, the through hole is designed to be circular.
[0018] To prevent gas backflow and maintain a clean and stable treatment environment, the opening and closing of the one-way valve is influenced by airflow. When gas flows along the inside of the tube toward the valve, the valve opens; when gas flows along the valve toward the inside of the tube, the valve closes. This one-way valve operating method of the nebulizer inhalation assist device controls airflow, provides a high degree of safety, and supports nebulizer inhalation therapy. It ensures the efficient delivery and utilization of drug aerosols.
[0019] Compared with the prior art, the beneficial effects of the present invention are mainly reflected in the following aspects:
[0020] 1. Improve the fun of the treatment process and increase the drug inhalation rate:
[0021] The addition of a color-changing windmill visually displays the extent of a patient's inhaled drug aerosol, making treatment more engaging and engaging, a potentially tedious process. More importantly, it provides medical staff with an intuitive observation window. By observing the windmill's rotation speed and color changes, medical staff can indirectly assess the stability of the treatment environment, the distribution of airflow, and the patient's respiratory status, allowing them to adjust treatment plans promptly to maximize treatment effectiveness.
[0022] 2. Optimization of air inlet and outlet:
[0023] When the patient inhales, the vaporized liquid medicine enters the tube through the through-hole and flows into the patient's body. When the patient exhales, the exhaled gas flows out of the tube through the one-way valve, effectively preventing outside air or the patient's exhaled gas from entering the device, avoiding reverse flow and contamination of the drug aerosol, maintaining the purity and activity of the drug aerosol, and ensuring the cleanliness and hygiene of the device, providing patients with a safer and more reliable treatment environment. In addition, the one-way valve can reduce unnecessary loss of drug aerosol during transmission, thereby reducing drug aerosol waste and ensuring that every drop of medicine can exert its maximum therapeutic effect. The one-way valve forms a seamless connection with the tube body, which ensures the smooth flow of air and prevents the loss of drug aerosol. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The drawings in this utility model are for illustrative purposes only and are not to be construed as limiting the scope of this utility model. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced in size, and do not represent the actual dimensions of the products. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted from the drawings.
[0029] Example 1
[0030] like Figure 1As shown, an atomization inhalation assist device of this embodiment includes a tube body 100, an oral tube 200, and a one-way valve 300. The oral tube 200 is funnel-shaped, with the narrow end of the oral tube 200 being used to contact the patient's mouth. The wide end of the oral tube 200 is connected to the tube body 100, and the other end of the tube body 100 is connected to the one-way valve 300. The one-way valve 300 and the tube body 100 form a seamless connection, ensuring smooth airflow and preventing the loss of drug aerosol. The tube body 100 is hollow, with a circular through hole 110 formed at the top of the tube body 100. The through hole 110 is located in the middle of the through hole 110. The observation device 120 can be specifically a windmill. The windmill includes multiple blades, which are designed to be yellow and blue or red and blue. When young children inhale drug aerosols, the windmill can enhance the patient's treatment experience and sense of participation. It also incorporates an observation function, which makes it easier for medical staff and patients to intuitively understand the treatment progress. The highlight of the windmill is the yellow and blue or red and blue blades. When the patient inhales, the drug aerosol continuously flows into the tube body 100 through the through hole 110. The windmill inside the through hole 110 rotates with the airflow, and the drug aerosol enters the patient's body along the oral tube 200. When the airflow rate reaches a level that allows the patient to inhale the drug aerosol into the lungs, the windmill's blades will appear green or purple. By observing the rotation speed and color change of the windmill, medical staff can indirectly assess the stability of the treatment environment, the distribution of the airflow, and the patient's respiratory status, so as to adjust the treatment plan in a timely manner, improve the efficiency and accuracy of drug inhalation, and ensure that every drop of precious drug liquid can be accurately delivered to the lesion, thereby accelerating the treatment process and improving the treatment effect. In addition, the windmill design increases the interest of the treatment, making the boring treatment process lively and interesting.
[0031] In this embodiment, combined with Figure 2 As shown, the windmill is combined with the tube body. This design reduces the need for the windmill as an independent component to be installed in the tube body in traditional devices, simplifies the operation process, improves the convenience of the atomizing inhalation auxiliary device during disassembly and installation, and avoids problems such as air leakage and looseness caused by improper installation.
[0032] In this embodiment, if Figure 3As shown, the connecting end of the one-way valve is provided with an elastic outer edge 310, and a groove (not marked in the figure) is provided at the connection between the tube body 100 and the one-way valve 300. The shape and size of the groove match the specific part of the one-way valve. The elastic outer edge 310 is embedded in the groove in the tube body. The elastic outer edge 310 is made of a highly elastic and wear-resistant material with good flexibility and resilience, and can fit closely to the contour of the groove of the tube body 100. When the one-way valve 300 is installed on the tube body 100, the elastic outer edge 310 will naturally expand and embed into the groove in the tube body 100, forming a tight, almost leak-free sealed connection, which not only simplifies the installation process and enables the one-way valve 300 to be easily and quickly fixed on the tube body 100, but also effectively prevents leakage of the fluid during transmission through the close fit between the elastic outer edge 310 and the groove, ensuring the overall sealing and reliability of the device. At the same time, the presence of the elastic outer edge 310 can also absorb and alleviate the stress caused by fluid pressure changes or vibrations to a certain extent, protect the connection parts from damage, and extend the service life of the device.
[0033] In this embodiment, combined with Figure 3 and Figure 4 As shown, when the one-way valve 300 is in the open state, the gas flows along the inside of the tube body 100 toward the one-way valve 300, and the patient is in the exhalation state. When the one-way valve 300 is in the closed state, there are two situations: one is that the gas flows along the one-way valve 300 toward the inside of the tube body 100, and the patient is in the inhalation state; the other is the static state. The one-way valve 300 remains closed, which can reduce unnecessary loss of drug aerosol during transmission, thereby reducing drug aerosol waste and ensuring that every drop of drug can exert its maximum therapeutic effect. It also effectively prevents external air or gas exhaled by the patient from entering the device, avoiding reverse flow and contamination of the drug aerosol, maintaining the purity and activity of the drug aerosol, and ensuring the cleanliness and hygiene of the device, providing a safer and more reliable treatment environment for patients.
[0034] In addition, in order to reduce medical costs while ensuring the hygiene standards and safety of the device for reuse, the atomizing inhalation assist device is designed to be resistant to high-temperature disinfection. The tube body 100, oral tube 200, and one-way valve 300 are all made of heat-resistant materials. These materials can not only maintain structural stability in high-temperature environments and effectively resist thermal stress and deformation, but also have excellent chemical stability, preventing adverse reactions with disinfectants during the disinfection process, ensuring the long-term performance of the device. In addition, the tube body 100, oral tube 200, and one-way valve 300 are detachable and installable, which not only facilitates medical staff to quickly assemble and disassemble according to actual needs, but also shows significant advantages in the cleaning and maintenance links. When the device needs to be cleaned, the various components are separated to thoroughly remove dirt, residual drugs, or microorganisms that may have accumulated during use, thereby achieving a deeper cleaning effect and ensuring that the device can meet medical-grade hygiene standards before each use. In addition, the detachable installation feature also facilitates the individual replacement of components. When a component is worn or damaged, there is no need to replace the entire device, only the corresponding component needs to be replaced, further reducing maintenance costs. This design not only reflects the effective use of resources, but also conforms to the current environmental protection concept of sustainable development.
[0035] Example 2
[0036] A working method of a windmill of a nebulization inhalation assist device is implemented based on the above-mentioned nebulization inhalation assist device. Specifically, when the patient takes a deep breath, the one-way valve 300 is in a closed state, and the airflow enters the tube body through the through hole 110. The windmill rotates rapidly under the influence of the inhaled airflow, and the fan blades appear green or purple. At this time, the closure of the one-way valve 300 prevents outside air from entering the interior of the device, avoids the loss of drug aerosol, maintains the purity and activity of drug aerosol, and creates a safer and more comfortable treatment environment for patients. This windmill working method of the nebulization inhalation assist device uses the patient's own inhalation force to drive the windmill to rotate, and is combined with a visual feedback mechanism, which not only improves the effect of nebulization inhalation treatment, but also enhances the user experience.
[0037] Example 3
[0038] A method for operating a one-way valve of an atomizing inhalation assist device is implemented based on the above-mentioned atomizing inhalation assist device. Specifically, the one-way valve operates as follows: when gas flows along the inside of the tube body toward the one-way valve, the one-way valve opens; when gas flows along the one-way valve toward the inside of the tube body, the one-way valve closes, preventing the patient's exhaled gas from entering the device, thereby preventing the drug aerosol from being contaminated, maintaining the purity and activity of the drug aerosol, and ensuring the cleanliness and hygiene of the device, providing patients with a safer and more reliable treatment environment. This method for operating a one-way valve of an atomizing inhalation assist device controls the outflow of airflow, has a high degree of safety, and provides support for atomizing inhalation treatment. It not only ensures the efficient transmission and utilization of drug aerosols, but also maintains the cleanliness and stability of the treatment environment by preventing gas backflow.
[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation methods of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of the present invention shall be included within the scope of protection of the claims of the present invention.
