Description

Technical Field

[0001] This utility model relates to the field of nebulization devices, and more specifically, to a pediatric pulmonary drug delivery nebulization inhalation device. Background Technology

[0002] The nebulizer body can be made of medical-grade plastic, such as polypropylene (PP) or polycarbonate (PC). These materials have good chemical resistance, high temperature resistance, and mechanical strength, ensuring that they will not deform or crack during prolonged use. For example, PP nebulizer bodies can withstand high-temperature sterilization up to 120°C, while PC materials have higher transparency, making it easy to observe the remaining amount of medication inside.

[0003] When a pediatric pulmonary nebulizer is tilted, the distribution of the medication in the storage chamber changes. If the tilt angle is large, the atomized particles may change direction due to gravity, directly impacting the child's airway walls or forming localized accumulations within the airway. For example, medication particles that should be evenly distributed in the airway may concentrate in a certain area, increasing the risk of airway obstruction. This is especially true for young children, whose airways are relatively narrow and more susceptible to the effects. Furthermore, because children are active, it is necessary to prevent false alarms caused by children's movement. Therefore, a pediatric pulmonary nebulizer with a tilt alarm mechanism needs to be designed to address these issues. Utility Model Content

[0012] 3. Beneficial effects

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) During the treatment process of this method, when the nebulizer bottle is tilted, the impact ball inside the hollow follower bottle on the side of the nebulizer bottle tilts due to gravity, and eventually the arc-shaped impact piece on the side of the impact ball impacts the inner wall of the hollow follower bottle. After the impact, the protrusion pushes inward, causing the protrusion to contact the contact sensor. After the contact sensor receives the contact signal, the alarm is promptly issued by the controller to remind medical staff or parents to adjust the position of the nebulizer bottle. After the nebulizer bottle is in the correct position, the position of the impact ball is reset. This helps to ensure that the medicine in the nebulizer bottle can be output in the correct way, and to ensure the stability of the size and concentration of the nebulized particles.

[0015] (2) After the nebulization is completed, the hollow follower bottle can be slid down from the slide groove by locking the outer ring. During the sliding process, the hollow follower bottle can be removed, which makes it easier for medical staff to clean and disinfect the nebulization bottle. At the same time, a silicone inner ring is set inside the nozzle cover. The silicone inner ring makes the nozzle cover more gentle when it comes into contact with the child's face during the nebulization operation, making the treatment process more humane.

[0016] (3) Prevent accidental contact of the touch sensor due to children shaking or other reasons, which may cause false alarms due to tilt. Attached Figure Description

[0026] Example:

[0027] Please see Figure 1-4 A pediatric pulmonary nebulization inhalation device includes a nebulizer bottle 1, a connection port 2 installed on the upper front side of the nebulizer bottle 1, a nozzle cover 3 installed at the front end of the connection port 2, a hollow follower bottle 9 provided at the right end of the nebulizer bottle 1, a fixing block 11 fixedly connected to the upper inner wall of the hollow follower bottle 9, a rotating shaft 12 fixedly connected to the lower end of the fixing block 11, a connecting rod rotatably connected to the outer end of the fixing block 11, an impact ball 13 fixedly connected to the lower end of the connecting rod, a spring 14 fixedly connected to the right end of the impact ball 13, an arc-shaped impact piece 15 fixedly connected to the end of the spring 14 away from the impact ball 13, and arc-shaped impact pieces 15 symmetrically fixedly connected to the upper and lower sides of the end of the arc-shaped impact piece 15 close to the impact ball 13, and contact sensors 17 symmetrically fixedly connected to the upper and lower sides of the right end of the impact ball 13.

[0028] Please see Figure 1-4The contact sensor 17 and the protrusion 16 cooperate with each other. The front and rear ends of the atomizing bottle 1 are symmetrically provided with sliding grooves 7. The outer ends of the two sliding grooves 7 are slidably connected with the locking outer ring 8. The locking outer ring 8 is connected to the hollow follower bottle 9. The rear end of the atomizing bottle 1 is fixedly connected with the handle 6. The left and right ends of the nozzle cover 3 are symmetrically installed with head binding ropes 5. The two head binding ropes 5 are bound to each other. The rear end of the nozzle cover 3 is fixedly connected with the silicone inner ring 4. The upper end of the hollow follower bottle 9 is fixedly connected with the alarm 10. The inner end of the alarm 10 is fixedly connected with the controller. The controller is electrically connected to the alarm 10 and the contact sensor 17 through a wire. The controller also includes a false alarm prevention device. The false alarm prevention device includes a counter. The counter counts the signal of the contact sensor (17). The lower end of the atomizing bottle 1 is provided with a hose 18.

[0029] Please see Figure 1-4 This method involves injecting the medication into the nebulizer bottle 1 according to the doctor's prescription and connecting the nozzle cover 3 to the nebulizer bottle 1 via the connection port 2. This ensures the nozzle cover 3 is aligned with the child's airway, allowing the device to operate for optimal therapeutic effect. During treatment, when the nebulizer bottle 1 tilts, the impact ball 13 inside the hollow follower bottle 9 on the side of the nebulizer bottle 1 tilts due to gravity, ultimately causing the arc-shaped impact piece 15 on the side of the impact ball 13 to impact with the inner wall of the hollow follower bottle 9. After the impact, the protrusion 16 pushes inward, causing it to contact the contact sensor 17. After receiving a contact signal, the touch sensor 17 outputs a signal that is counted by a counter. When the contact count reaches a certain threshold within a set time period, the false alarm prevention device, through the controller, sends an alarm to the alarm 10, reminding medical staff or parents to adjust the position of the nebulizer bottle 1. Once the nebulizer bottle 1 is in the correct position, the impact ball 13 returns to its original position. This helps ensure that the medication in the nebulizer bottle 1 is output correctly, ensuring stable particle size and concentration. It also eliminates false alarms caused by accidental contact of the touch sensor due to children shaking the device. After nebulization, the hollow follower bottle 9 can be slid down from the slide groove 7 by engaging the outer ring 8. During the sliding process, the hollow follower bottle 9 is removed, facilitating cleaning and disinfection of the nebulizer bottle 1 by medical staff. Additionally, a silicone inner ring 4 is provided inside the nozzle cover 3, making the contact between the nozzle cover 3 and the child's face gentler during nebulization, thus making the treatment process more humane.

[0030] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
