Description

Technical Field

[0001] This utility model relates to the technical field of nebulizers, specifically a pediatric anti-backflow nebulizer. Background Technology

[0002] Medical nebulizers are primarily 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. This is especially beneficial for children, who are more susceptible to respiratory infections due to their weaker immune systems.

[0003] According to Chinese Patent No. CN219462195U, a pediatric nursing nebulizer includes a nebulizer body, a motor fixedly connected to the bottom of the nebulizer body, a partition fixedly connected to the inner wall of the nebulizer body, the output shaft of the motor rotatably passing through the bottom of the partition, and a spray button provided on the outer wall of the nebulizer body. The nebulizer body is characterized by having a mist outlet tube fixedly connected to the outer wall of the nebulizer body, a sleeve slidably fitted onto the outer wall of the mist outlet tube, a rubber cover fixedly connected to one side of the sleeve, a sealing box slidably connected to the inner wall of the nebulizer body, a rotating rod fixedly connected to the bottom of the sealing box, multiple sets of stirring blades fixedly fitted onto the outer wall of the rotating rod, and a first fixing component rotatably connected to the top of the sealing box for fixing the position of the sealing box.

[0004] In the above solution, the liquid medicine is poured into the nebulizer body, and after being atomized, it is transmitted from the mist outlet tube to the rubber cover for children to inhale through their mouths. This has the following disadvantages: during nebulization, children are prone to shaking the nebulizer, and since the nebulizer does not have an anti-backflow structure, the liquid medicine in the nebulizer is prone to spilling out from the mist outlet tube, which reduces the efficiency and safety of nebulization. Utility Model Content

[0005] The purpose of this invention is to provide a pediatric anti-backflow nebulizer to solve the problem that children tend to shake the nebulizer during nebulization, and the nebulizer does not have an anti-backflow structure, which makes it easy for the liquid medicine in the nebulizer to spill out from the mist outlet tube, thus reducing the efficiency and safety of nebulization.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a pediatric anti-backflow nebulizer, comprising a cup lid, the cup lid being detachably mounted on the top of a transparent cup body, a mist outlet being provided on the front side of the outer wall of the transparent cup body, a cup core being fixed on the bottom surface of the cup lid, an anti-backflow block being fixed on the front side of the inner wall of the transparent cup body, the anti-backflow block being shaped like a frustum, a flow hole being provided at the front end of the anti-backflow block, the flow hole corresponding to the mist outlet, a mist outlet tube being fixed on the front side of the outer wall of the transparent cup body, the through hole of the mist outlet tube corresponding to the mist outlet, and a face mask being detachably mounted on the outer wall of the mist outlet tube, the face mask being interference-fitted with the mist outlet tube.

[0007] Preferably, the inner wall of the mist outlet pipe is fixed with several anti-backflow inclined plates.

[0008] Preferably, the inner wall of the transparent cup body is provided with internal threads, and the outer wall of the cup lid is provided with external threads, and the external threads are threadedly connected to the internal threads.

[0009] Preferably, a rubber ring is fixed to the front side of the mask.

[0010] Preferably, a scale is provided on the right side of the outer wall of the transparent cup.

[0011] Preferably, the thickness of the rubber ring is 0.5 cm.

[0012] Compared with existing technologies, a pediatric anti-backflow nebulizer that adopts the above-mentioned technical solution has the following beneficial effects:

[0013] First, during use, the anti-backflow block helps to prevent the liquid inside the transparent body from flowing back. Even if a child shakes the transparent cup, it can prevent the liquid inside the transparent cup from accidentally spilling out of the mist outlet, thereby improving the atomization efficiency, ensuring the smooth atomization process and the safety of children.

[0014] Second, during use, as atomization progresses, the anti-backflow ramp further prevents the liquid from flowing back out of the transparent cup. Even if the transparent cup is shaken or tilted, the anti-backflow ramp effectively blocks the flow of the liquid, preventing spillage and ensuring the continuity and stability of atomization, thus further enhancing the anti-backflow effect. The operator can securely connect and fix the cup lid to the transparent cup using the tight fit of the internal and external threads. This connection method is not only simple and easy to implement but also highly reliable, ensuring the stability and sealing of the atomizer during use.

[0015] Thirdly, during use, the rubber ring fits tightly against the front of the mask, providing extra sealing and cushioning between the mask and the child's face. This not only enhances the mask's seal and prevents fogging leakage but also improves the child's comfort, reducing pressure on the face and providing a safer and more comfortable nebulization experience. Using the scale on the right side of the transparent cup's outer wall, staff can clearly observe the amount of medication poured in, avoiding issues of too much or too little medication. This makes adding medication more accurate and convenient, and also provides strong assurance for the nebulization effect. By setting the rubber ring thickness to 0.5cm, sufficient sealing is ensured while avoiding excessive pressure on the face. This design makes the mask more comfortable and fits better when worn, while also improving the nebulization effect. Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a pediatric anti-backflow nebulizer includes a cup lid 1, which is detachably mounted on the top of a transparent cup body 2. A mist outlet 3 is provided on the front side of the outer wall of the transparent cup body 2. A cup core 4 is fixed on the bottom surface of the cup lid 1. An anti-backflow block 5 is fixed on the front side of the inner wall of the transparent cup body 2. The anti-backflow block 5 is shaped like a frustum. A flow hole 6 is provided at the front end of the anti-backflow block 5, which corresponds to the mist outlet 3. A mist outlet tube 7 is fixed on the front side of the outer wall of the transparent cup body 2. The through hole of the mist outlet tube 7 corresponds to the mist outlet 3. A face mask 8 is detachably mounted on the outer wall of the mist outlet tube 7, and the face mask 8 is interference-fitted with the mist outlet tube 7.

[0023] In use, the staff first connects the tubing to the bottom of the transparent cup 2, then connects the other end of the tubing to the nebulizer. Next, they open the cup lid 1 and pour the medicine into the inside of the transparent cup 2. Then, they install the cup lid 1 on the transparent cup 2 and place the mask 8 over the child's face. When the nebulizer is activated, even if the child shakes the transparent cup 2, the anti-backflow block 5 can effectively prevent the medicine inside the transparent cup 2 from accidentally spilling out of the mist outlet 3, thereby improving the nebulization efficiency and ensuring the smooth operation of nebulization and the child's safety.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, several anti-backflow inclined plates 9 are fixed on the inner wall of the mist outlet pipe 7.

[0025] During use, as atomization proceeds, the anti-backflow ramp 9 further prevents the liquid from flowing back out of the transparent cup 2. Even if the transparent cup 2 is shaken or tilted, the anti-backflow ramp 9 can effectively block the flow of the liquid and prevent it from spilling, thereby ensuring the continuity and stability of atomization and further enhancing the anti-backflow effect.

[0026] like Figure 1 and Figure 2 As shown, the inner wall of the transparent cup body 2 is provided with an internal thread 10, and the outer wall of the cup lid 1 is provided with an external thread 11. The external thread 11 is threadedly connected to the internal thread 10, and a rubber ring 12 is fixed on the front side of the mask 8.

[0027] During use, the operator can securely connect and fix the cup lid 1 to the transparent cup body 2 through the tight fit of the internal thread 10 and the external thread 11. This connection method is not only simple and easy to implement, but also very reliable, ensuring the stability and sealing of the atomizer during use. The rubber ring 12 fits tightly against the front of the mask 8, providing additional sealing and cushioning between the mask 8 and the child's face. This not only enhances the sealing of the mask 8 and prevents fog leakage, but also improves the comfort of children when wearing it, reduces pressure on the face, and provides children with a safer and more comfortable vaping experience.

[0028] like Figure 1 and Figure 2 As shown, a scale 13 is provided on the right side of the outer wall of the transparent cup body 2, and the thickness of the rubber ring 12 is 0.5cm.

[0029] During use, the scale 13 on the right side of the outer wall of the transparent cup 2 allows staff to clearly observe the amount of liquid being poured in, thus avoiding the problem of too much or too little liquid. This makes adding the liquid more accurate and convenient, and also provides a strong guarantee for the atomization effect. By setting the thickness of the rubber ring 12 to 0.5cm, sufficient sealing is ensured while avoiding excessive pressure on the face. This design makes the mask 8 more comfortable and fits better when worn, and also improves the atomization effect.
