Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to an atomization device for newborns. Background Art

[0002] Among medical devices, neonatal nebulizers are mainly used to convert liquid medicine into fine droplets, making it easier to absorb and helping to relieve respiratory diseases. However, the existing neonatal nebulizers on the market currently have many problems in practical applications, especially in terms of comfort and convenience for neonates. Existing nebulizers usually fix the mask to the face of the newborn through straps or a tight hoop structure. Although this traditional fixing method can maintain the fit between the mask and the face to a certain extent, due to the delicate and sensitive skin of the newborn, the strap-type fixing method often puts pressure on the facial skin, causing discomfort, and may even cause redness, swelling or pressure injuries. And because newborns have limited mobility, they are more likely to show obvious resistance to this kind of binding feeling, which increases the difficulty of nursing operations.

[0003] In addition, existing atomizers usually install the liquid medicine storage bottle directly on the upper part or side of the mask. To ensure the smooth output of the liquid medicine and the atomization effect, the liquid storage bottle must always remain in a vertical position during use. If the newborn turns his head or moves slightly, the bottle may tilt, resulting in the loss of liquid medicine or poor atomization effect. This design requires the caregiver to always pay attention to the position of the bottle during treatment and constantly adjust the mask and the newborn's head to ensure a stable atomization effect. This design not only affects the convenience of using the atomizer, but also makes it difficult for caregivers to take care of newborns efficiently.

[0004] In addition, existing atomizers need to be cleaned and dried after use to ensure sanitary conditions for the next use. However, traditional atomizers are usually placed directly on the table to control water after cleaning. Residual water after cleaning tends to accumulate on the table or around the device, causing a risk of contamination. The accumulation of water droplets can easily cause the device parts to come into contact with bacteria, thereby increasing the possibility of infection. Especially for atomizers that need to be used frequently, incomplete cleaning or improper water control may cause secondary contamination problems, which directly affects the health of newborns. Summary of the invention

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention abandons the traditional strap-type fixing method and adopts a non-restrained self-weight pressing design to fix the mask on the connector, and the device is firmly placed on the forehead and both sides of the head of the newborn through the fitting of the arc-shaped pad and the splint. During use, the mask is lightly buckled on the mouth and nose of the newborn, and there is no need to press the newborn's face with straps, which effectively reduces the discomfort and pressure caused by the fixing device. This design not only ensures the stability of the mask, but also makes the wearing process more comfortable, allowing the newborn to quietly undergo atomization treatment, which helps to improve the atomization effect and reduce the resistance of the newborn.

[0023] The liquid medicine bottle of the present invention adopts an automatic vertical design, and the bottle is fixed by a round tube and a connector. When the newborn's head turns left or right or shakes slightly, the bottle can automatically adjust its position by its own gravity to maintain a vertical state. No matter how the newborn's head moves, the bottle can always maintain the correct position without tilting or affecting the normal flow of the liquid medicine. This design not only simplifies the operation of the nursing staff and eliminates the trouble of frequently adjusting the bottle, but also improves the user experience of the device while ensuring the atomization effect. The function of the bottle body always remaining vertical ensures that the liquid medicine flows smoothly, so that the newborn can obtain a stable and continuous atomization effect during the atomization treatment process.

[0024] The present invention designs an intelligent magnetic locking and unlocking mechanism, which locks the bottle body when the compression pump is not started through the repulsive effect between the first annular magnet and the second annular magnet, so as to prevent the bottle body from accidentally rotating or falling off the connector. When the compression pump is started, the air pressure in the guide air chamber increases, partially offsetting the repulsive force between the magnets, and the bottle body can rotate freely in the connector, which is convenient for adjusting the bottle body during the activities of the newborn. This intelligent locking and unlocking design enhances the stability and safety of the device, avoids the problem of liquid medicine loss caused by misoperation, and effectively improves the reliability of the device.

[0025] This device uses a sophisticated design of the air inlet pipe, guide air chamber and nozzle to enable the airflow generated by the compression pump to efficiently atomize the liquid medicine. When the airflow passes through the nozzle, a high-speed jet is formed. Under the action of negative pressure, the liquid medicine is sucked out of the suction pipe and atomized into fine particles, which are then dispersed into the mask through the septum, ensuring that the newborn can continuously and evenly inhale the liquid medicine. This design effectively solves the problem of unstable atomization effect caused by tilted bottle or insufficient airflow in the prior art, enhances the absorption effect of the liquid medicine, and further improves the efficacy of atomization treatment.

[0026] In order to ensure the hygiene of the atomizer device, the present invention can rotate the atomizer bottle 180 degrees and invert it on the rack to control water after cleaning, avoiding the pollution problem caused by water droplets remaining when the traditional device is placed directly on the desktop. The inverted water control design allows the device to be completely dried, reduces the risk of bacterial growth, and ensures the cleanliness and hygiene of each use. This design not only meets the hygiene standards of medical devices, but also saves time and effort for nursing staff during daily maintenance, further ensuring the safety of newborns.

[0040] The present invention will be further described below in conjunction with the accompanying drawings.

[0041] like Figures 1 to 9 As shown, a nebulizer device for neonates includes a compression pump 1, a nebulizer bottle and a mask 8. The mask 8 is mounted on the nebulizer bottle. The compression pump 1 and the nebulizer bottle are connected by a hose 2. The whole system forms a closed liquid medicine nebulization channel, which is convenient for neonates to smoothly inhale liquid medicine during treatment. The nebulizer bottle includes the following main components:

[0042] The bottle body 3 is provided with an atomizing chamber 16 inside, which serves as the core space for containing the medicine liquid and performing atomization treatment. The top opening of the bottle body 3 is connected to the atomizing chamber 16 for facilitating the addition of medicine and exhaust. A medicine liquid pool 15 is fixed inside the atomizing chamber 16, and the medicine liquid pool 15 is used to hold the therapeutic medicine liquid. The fixed installation design prevents the medicine liquid from overflowing when the bottle body 3 is tilted, and at the same time ensures the uniform distribution of the medicine liquid. A nozzle 14 is also fixedly installed in the medicine liquid pool 15, and a high-pressure air pipe 13 is connected to the bottom of the nozzle 14. A water suction pipe is fixedly arranged outside the nozzle 14, which can accurately suck out the medicine liquid from the medicine liquid pool 15 under the action of negative pressure to prevent the waste of excess medicine liquid.

[0043] The dosing tube 11 is inserted downward from the top opening of the bottle body 3 into the atomizing chamber 16, and a diaphragm is fixed at the bottom, which is located above the nozzle 14 to facilitate the control of the atomization flow of the liquid medicine. A liquid adding hole 12 is designed at the top of the dosing tube 11 to facilitate the replenishment of the liquid medicine through this hole. The structure and principle of the high-speed airflow ejected by the nozzle 14 driving the liquid medicine to become an atomized state are conventional means.

[0044] The connector 4 can be rotatably mounted on the circular tube 9 of the bottle body 3, and a guide air chamber 21 is arranged inside. The guide air chamber 21 is connected to the annular air chamber 18 on the bottle body 3 through an internal design to achieve a continuous atomization effect of the liquid medicine. An air inlet pipe 10 is fixedly arranged on the outside of the connector 4, which is used to transport the compressed gas generated by the compression pump 1 through the hose 2 to the guide air chamber 21 to achieve continuous and uniform atomization of the liquid medicine. At the same time, a mask 8 is fixedly installed on the end of the connector 4 away from the circular tube 9 to ensure that the mask 8 and the liquid medicine output end are accurately aligned when the newborn wears it, so as to maintain efficient delivery of the liquid medicine.

[0045] In this embodiment, a screening plate 17 is fixedly provided at the bottom of the dosing tube 11, and the screening plate 17 is located outside the diaphragm and is arranged around the diaphragm. The design of the screening plate 17 can effectively filter the larger particles of the liquid medicine, ensure that the liquid medicine entering the atomization area is more uniform and fine, and prevent overly large particles from entering the nozzle 14 and affecting the atomization effect.

[0046] In this embodiment, a one-way valve is installed in the liquid filling hole 12. The design of the one-way valve can avoid the reverse flow of gas or liquid medicine while ensuring that the liquid medicine can be replenished at any time, preventing liquid medicine contamination or leakage, and enhancing the safety of the device.

[0047] In this embodiment, a plurality of air holes 25 are arranged inside the circular tube 9, and the air holes 25 are evenly distributed around the circular tube 9 in a circular array to form a stable air flow direction. The axis of the air hole 25 is parallel to the axis of the circular tube 9, ensuring uniform air flow and achieving a stable atomization effect. The other end of the air hole 25 is connected to the annular air chamber 18, and the gas enters the guide air chamber 21 through the air hole 25 and finally reaches the mask 8, achieving stable breathing for the newborn.

[0048] The connector 4 is provided with an annular opening 27 at one end facing the circular tube 9, and the annular opening 27 is connected to the guide air chamber 21. One end of the circular tube 9 is rotatably inserted into the annular opening 27, so that the entire atomizing device maintains dynamic balance during use and reduces the inconvenience caused by movement. A first sleeve 19 is installed inside the annular opening 27 to stabilize the rotation connection of the circular tube 9, while the second sleeve 20 is fixedly connected to the circular tube 9. The design of the two sleeves ensures that the circular tube 9 can remain stable during rotation to avoid jamming.

[0049] The bottle body 3 is rotatably mounted on the connector 4, and the round tube 9 on the bottle body 3 is located at the upper part of the outer surface of the bottle body 3. Under the action of the gravity of the bottle body 3, the bottle body 3 can always maintain a vertical state; the hose 2 of the compression pump 1 is connected to the connector 4. When the newborn's head shakes left and right, the hose 2 will not affect the vertical state of the bottle body 3, thereby ensuring that the medicine can be continuously atomized.

[0050] In this embodiment, an annular groove 23 is provided on the circular tube 9, which is located in the annular opening 27 and is used to accommodate the magnet structure. The first annular magnet 22 and the second annular magnet 24 are installed in the groove, and the inner and outer rings of the magnets are fixed to the circular tube 9, and the ends with the same magnetic poles are opposite to each other, so as to ensure the stability of the circular tube 9 by repulsive force and prevent it from accidentally moving when it does not need to rotate. The first annular magnet 22 and the second annular magnet 24 are designed to be spaced apart to control the range of movement of the circular tube 9 and ensure the effective repulsive force of the magnets.

[0051] When the compression pump 1 is not working, the first annular magnet 22 and the second annular magnet 24 repel each other, pressing the outer side of the circular tube 9 into the annular opening 27. At this time, the connector 4 will rub tightly against the circular tube 9, and the bottle body 3 cannot rotate freely on the connector 4. When the compression pump 1 is working, the air pressure in the guide air chamber 21 increases, offsetting part of the repulsive force between the first annular magnet 22 and the second annular magnet 24, and the circular tube 9 slides a distance toward the outside of the annular opening 27. At this time, the circular tube 9 can rotate freely in the annular opening 27. By rotating, because the inner diameter of the second annular magnet 24 is larger than the inner diameter of the first annular magnet 22 and smaller than the outer diameter of the first annular magnet 22, it is ensured that the circular tube 9 will not fall out of the annular opening 27, and the gas enters the nozzle 14 from the air inlet pipe 10 and the guide air chamber 21 through the annular opening 27, the air hole 25, and the high-pressure air pipe 13, and is ejected at a high speed through the nozzle 14. Under the action of negative pressure, the liquid in the liquid pool 15 is sprayed to the partition through the water suction pipe, becomes mist, and then enters the mask 8 through the channel in the circular tube 9 and the connector 4.

[0052] In this embodiment, a holder is installed on the mask 8. The holder structure includes an arc-shaped pad 5, a connecting rod 7 and a clamp 6. The reasonable structure allows the mask 8 to be worn on the face of a newborn baby stably and comfortably. The arc-shaped pad 5 is installed on both sides of the mask 8, and a silicone pad is arranged inside to increase the softness when worn. The arc-shaped pad 5 is designed with multiple air holes 25 to increase air permeability, avoid oppression on the skin of the newborn baby, and improve comfort.

[0053] The mask 8 is fixedly mounted on the connector 4. When the newborn baby takes a semi-lying position for atomization treatment, the mask 8 is buckled on the mouth and nose, the arc-shaped pad 5 is attached to the forehead, and the splints 6 are clamped on both sides of the newborn baby's head. The mask 8 is pressed against the newborn baby's face by the device's own weight, making it more convenient to wear and reducing the discomfort of the traditional strap-type fixation on the newborn baby.

[0054] The atomizer is usually reusable and can be cleaned and dried after use. The existing atomizer is placed directly on the table to drain water after being rinsed with water. The water that flows down accumulates on the table and sticks to the atomizer bottle, mask 8 and other parts, which is easy to cause pollution. In order to solve this problem, in this embodiment, if Fig.10 , Fig.11As shown, the device is also equipped with a rack to facilitate the atomizing device to be hung and dried after use. The rack includes a base 30, a support rod 32 and an arc-shaped support plate 28, wherein the base 30 is designed with a water collection tank 31 for receiving water droplets after cleaning to ensure a clean use environment. The support rod 32 fixes the arc-shaped support plate 28 to the base 30, and the card hole on the arc-shaped support plate 28 is convenient for placing the air intake pipe 10. Through the design of the card hole, the entire device can be firmly fixed on the rack to dry the residual water in an inverted state. After cleaning, the atomizing bottle is rotated 180 degrees, and then the atomizing bottle is placed on the rack in an inverted state to control water, thereby avoiding pollution problems.

[0055] In this embodiment, a bent portion is provided on the base 30, and a positioning hole 34 is designed on the bent portion. A positioning rod 33 is inserted into the positioning hole 34 and fixedly connected to the positioning seat 29, so as to facilitate the positioning of the device when placed. The bottom of the positioning seat 29 has an adhesive sticker, which can effectively fix the base 30 so that the atomizing device will not slide or tip over when controlling water.

[0056] In this embodiment, a drainage hole 26 is further provided at the lower part of the mask 8 for emergency discharge of the vomit of the newborn to prevent the mouth and nose from being blocked. At the same time, it is convenient to quickly discharge excess liquid or water during cleaning or use, so as to keep the mask 8 clean and dry, which helps to extend the service life of the device and enhance the user experience.

[0057] Working principle:

[0058] The atomization device for newborns compresses gas into the atomization bottle through a compression pump 1, and uses the device structure design to achieve a continuous and stable atomization process, ensuring efficient atomization and continuous supply of liquid medicine. The following is a detailed working principle:

[0059] Atomization process of liquid medicine: After the compression pump 1 is started, the compressed gas enters the air inlet pipe 10 on the connector 4 through the hose 2, and enters the annular air chamber 18 on the side of the bottle body 3 through the guide air chamber 21 inside the connector 4. The gas generates airflow in the high-pressure air pipe 13 and the air hole 25, and is distributed to the nozzle 14 through the annular air chamber 18, thereby generating a high-speed airflow at the outlet of the nozzle 14. The high-speed airflow, through the negative pressure effect, sucks the liquid medicine in the liquid medicine pool 15 from the water suction pipe to the diaphragm outside the nozzle 14, and the liquid medicine becomes atomized.

[0060] Fixing of the mask 8: The fixing device of the mask 8 uses the arc-shaped pad 5 and the splint 6 to firmly fit the mask 8 to the face of the newborn. The connecting rod 7 and the splint 6 exert appropriate clamping force on both sides of the newborn's head, and the silicone pad inside the arc-shaped pad 5 increases the wearing comfort and reduces the pressure of the mask 8. The mask 8 is stably pressed on the newborn's face by the device's own weight, without the need for traditional straps, which reduces the newborn's sense of restraint.

[0061] Stable design of the atomizer bottle: A first sleeve 19 and a second sleeve 20 are designed between the circular tube 9 and the connector 4 on the atomizer bottle to ensure that the bottle body 3 always remains in a vertical state when the newborn's head turns. In addition, an annular magnet is installed in the annular groove 23 of the bottle body 3 and the connector 4 to form a stable support for the bottle body 3. The first annular magnet 22 and the second annular magnet 24 support each other through magnetic pole repulsion, so that the bottle body 3 can switch between a rotatable vertical state and a fixed state.

[0062] Automatic water control and anti-pollution design: After use, the atomizer bottle can be rotated 180 degrees and inverted on the rack. The water collection tank 31 of the rack base 30 is used to collect residual water to avoid pollution. The clamping hole designed on the arc-shaped support plate 28 can stabilize the air inlet pipe 10, ensuring stable inverted water control, preventing water from remaining inside the device and avoiding pollution to the atomizer bottle and mask 8.

[0063] Directions:

[0064] Device preparation: Connect the compression pump 1, atomizer bottle and mask 8 through the hose 2, and inject the liquid medicine into the liquid medicine pool 15. Confirm that the one-way valve of the dosing tube 11 is normal, and inject the required liquid medicine into the open liquid filling hole 12 of the bottle body 3, and then fix and connect all components.

[0065] Wearing the mask 8: Wear the mask 8 on the newborn's face, making sure that the mouth and nose of the mask 8 are located directly in front of the newborn's mouth and nose. Stick the arc-shaped pad 5 to the forehead, and lightly clamp the two sides of the newborn's head with the splint 6. The mask 8 is lightly pressed on the face by the weight of the device to ensure a comfortable fit.

[0066] Start the compression pump 1: When the compression pump 1 is turned on, the compressed gas will enter the air inlet pipe 10 and the guide air chamber 21 through the hose 2. Under the action of the airflow, the liquid medicine in the liquid medicine pool 15 is sucked into the nozzle 14 through the water suction pipe and atomized. Ensure that the newborn breathes evenly and continuously atomizes and inhales the liquid medicine.

[0067] Cleaning and water control: After use, rinse the atomizer bottle, nozzle 14 and mask 8 with clean water, rotate the atomizer bottle to an inverted state and place it on the rack to control the water, ensuring that the water drips into the water collection tank 31 of the base 30 to keep the equipment clean.

[0068] Through this process, the device can safely and stably supply liquid medicine in aerosol form to newborns, effectively reducing the sense of restraint brought by traditional devices and improving safety of use.
