Description

Technical Field

[0001] This invention belongs to the field of nebulization therapy, specifically a neonatal nebulization therapy device. Background Technology

[0002] Nebulization therapy is a treatment method that transforms medication into tiny droplets, which are then inhaled into the lungs by the patient. Nebulization therapy is a common treatment for respiratory diseases in newborns, primarily used to relieve symptoms such as difficulty breathing and wheezing.

[0003] Neonatal nebulization therapy equipment mainly includes the following three common types: compressed air nebulizers, ultrasonic nebulizers, and mesh nebulizers. They all basically convert liquid medicine into fine mist particles, which are then passed into a mask for the newborn to absorb.

[0004] Traditional nebulizer treatments use relatively simple mask structures. Generally, the mask can only be pressed onto the newborn's face by hand or fixed with straps. The former requires the operator to keep pressing during treatment, while the latter requires the straps to be tied to the newborn's ears or the back of their head, which can cause discomfort to the newborn, leading to the newborn rejecting the mask and becoming even less willing to accept nebulizer treatment.

[0005] Therefore, the present invention provides a neonatal nebulization therapy device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a neonatal nebulization therapy device, including a breathing mask, a nebulization box is provided at the rear end of the breathing mask, the nebulization box and the breathing mask are connected by a connecting pipe, a vibrating mesh capable of vibration is installed at the end of the connecting pipe facing the nebulization box, a detachable power supply compartment is provided at the bottom of the nebulization box, a power cord is connected between the power supply compartment and the nebulization box, two symmetrically arranged ventilation holes are opened on the surface of the breathing mask, and multiple air ducts with outward output ends are installed on the outer side of the breathing mask;

[0008] The medication is first injected into the nebulizer box using a fan-operated system. The vibrating mesh within the box atomizes the medication. The basic principle is that a high-frequency vibrator generates mechanical vibration, forcing the medication through tiny holes in the mesh to form atomized particles. This atomized material is then transferred to a breathing mask via a connecting pipe. The mask is placed on the newborn's face, and multiple fans are activated to generate airflow, creating a thrust in the opposite direction. Since the newborn is lying down during nebulization, the friction between the mask and the newborn's face must exceed the mask's weight to prevent it from falling off. The power supply compartment is detachable, leaving only the nebulizer box and mask on the face. The combined weight of the two components and their internal parts is less than 100 grams, resulting in a combined weight of 1N. Since the coefficient of friction between the mask and the face is generally greater than 0.5, the thrust generated by the multiple fans only needs to exceed 2N. This design ensures that the breathing mask remains firmly in place on the newborn's face even when it is vertical, such as when the newborn rolls over to sleep on their side. The curved opening at the front of the mask allows for multi-angle support, further reducing the required thrust. With three nozzles, each only needs to generate a thrust of slightly more than 0.4N to achieve the desired effect. Regardless of how the newborn rolls over, the thrust from the nozzles remains directed towards the mask, preventing it from detaching from the face. This design allows the mask to remain in place on the newborn's face even without human intervention, while maintaining appropriate pressure to avoid causing excessive discomfort and increasing the newborn's willingness to receive nebulization therapy. Furthermore, the nebulizer box uses a mesh nebulizer design, resulting in extremely low noise. The multiple nozzles also do not require significant thrust, minimizing noise and preventing disruption to the newborn's sleep.

[0009] Preferably, there are three air ducts, two of which are located on both sides of the breathing mask and are symmetrically arranged. The remaining air duct is located on the outer side and upper part of the breathing mask. The outer side of each air duct has an air intake hole for inhalation. During operation, the resultant force of the three air ducts is perpendicular to the newborn's face. Therefore, as long as the breathing mask is placed accurately at the beginning, the breathing mask can be guaranteed to fit the face. The air ducts inhale around themselves, so that the force generated by inhalation will not affect the direction of the thrust. The arrangement of the three air ducts can better ensure that the resultant force of the air ducts is perpendicular to the newborn's face.

[0010] Preferably, the top surface of the atomizing box has a filling groove for filling liquid medicine. A movable seat is provided inside the filling groove. The height and width of the movable seat are the same as those of the filling groove. The movable seat is located on the side away from the vibrating mesh. An electric telescopic rod is fixedly connected inside the movable seat. The electric telescopic rod is fixedly connected to the inner wall of the atomizing box. A sealing cover is rotatably connected to the top of the atomizing box. During operation, the liquid medicine is added to the filling groove, the sealing cover is closed, and the electric telescopic rod is activated to push the position of the vibrating mesh of the movable seat to move, thereby pushing the liquid medicine to move. Excess air in the filling groove can directly pass through the vibrating mesh, while the liquid medicine is difficult to pass through the fine mesh without the assistance of vibration. This ensures that the liquid medicine can pass through the vibrating mesh constantly during the vibration atomization process.

[0011] Preferably, a sealing cover is fixed to the rear end of the breathing mask, and the connecting pipe passes through the sealing cover and communicates with the interior of the breathing mask. Two guide tubes are installed at the end of the connecting pipe. During operation, the guide tubes are designed to deliver the atomized medicine to the newborn's nose and mouth, so that the newborn can absorb more medicine vapor during inhalation. The ventilation holes allow outside air to enter the breathing mask normally and exchange with the air inside the breathing mask, ensuring normal oxygen absorption for the newborn.

[0012] Preferably, the guide tube is flat, and a connecting valve tube connected to the connecting tube is fixed between the rear ends of the two guide tubes. During operation, the atomized medicine discharged from the flat guide tube is more suitable for the shape of the newborn's nose and mouth absorption area, and the connecting valve tube can effectively distribute the atomized medicine from the connecting tube to the two guide tubes.

[0013] Preferably, multiple airflow detection modules are installed at the end of the guide tube. The multiple airflow detection modules are arranged linearly and equidistantly. An electromagnetic switching valve is fixed between two guide tubes. During operation, the airflow detection module can use a hot wire airflow sensor. The basic principle is that when the airflow passes through the sensor, the airflow will carry away some of the heat from the hot wire, causing the temperature of the hot wire to drop. Because the resistance of the heating wire changes with temperature, this temperature change causes a change in the resistance of the heating wire, thus detecting the airflow speed. When the newborn exhales through their mouth, the airflow detection module can detect this. The mesh nebulizer atomizes the medication and discharges it from the guide tube at room temperature and at a constant speed, so it does not affect the values ​​of the airflow detection module. When the newborn inhales through their nose and exhales through their mouth, an electromagnetic switching valve partially closes the guide tube near the mouth, allowing the medication to be concentrated and discharged from the guide tube near the nose. Conversely, the guide tube near the nose is closed, which maximizes the absorption efficiency of the medication. When exhaling through only the nose or mouth, the guide tube is also partially closed. This is because if the discharge of medication affects breathing, it will cause discomfort to the newborn or even cause choking. The medication discharged from the other guide tube will be mixed with air and normally inhaled by the newborn.

[0014] Preferably, a pressure ring is fixed to the front edge of the breathing mask. The pressure ring is made of elastic material and is hollow inside. An absorption hole is provided at the connection between the air duct and the breathing mask. During operation, the pressure ring provides a larger friction area and increases the coefficient of friction after contacting the newborn's face, thereby further ensuring the fit between the breathing mask and the newborn's face. When it is necessary to increase the nebulization speed, the air intake end of the air duct can be connected to the absorption hole, so that the air in the breathing mask can be quickly exchanged with the outside air, without causing a large amount of liquid to fill the mask and affect the newborn's breathing.

[0015] Preferably, the top of the power compartment is connected to the atomizing box by a snap-fit. The top of the power compartment has a storage slot. The power cord is spirally arranged and located in the storage slot. When working, the bottom of the power compartment is separated from the atomizing box, while the power cord remains connected for power transmission. The two can also be connected to each other, and the power cord can be stored in the storage slot for easy carrying of the device. At the same time, the device can also be used by hand.

[0016] Preferably, an alarm is installed on the top of the sealing cover, and observation windows communicating with the filling groove are opened on both sides of the atomizing box. During operation, the observation windows are used to observe the amount of liquid in the atomizing box. The alarm is triggered when the airflow detection module detects abnormal data. When a cough occurs, the airflow suddenly increases, and the airflow detection module can detect this and promptly transmit the information to the alarm.

[0017] Preferably, a fixing strip is fixed to the outside of the power compartment. The fixing strip is made of flexible material, and a flexible magnetic sheet is fixed to one end of the fixing strip. A magnetizable metal strip is provided inside the fixing strip. During operation, the fixing strip can be used to wrap around the object, and then the magnetic sheet is used to attract it, thus fixing the power compartment.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The neonatal nebulization therapy device of the present invention, through the setting of the air ducts, places the breathing mask on the face of the newborn, and activates multiple air ducts to generate outward air force, so that the air ducts generate thrust in the opposite direction; at the same time, in conjunction with the arc-shaped opening at the front end of the breathing mask, the breathing mask can be supported by multiple angles, further reducing the thrust requirement; no matter how the newborn rolls over, because the thrust generated by the air ducts on the breathing mask is always directed towards the breathing mask, the breathing mask will not fall off the newborn's face. Through this setting, the breathing mask can be kept on the newborn's face without operation, and the force is appropriate, so as not to make the newborn feel excessively uncomfortable, thereby increasing the newborn's willingness to accept nebulization therapy; and the nebulization box adopts a mesh nebulizer design, which produces extremely low noise, and the multiple air ducts do not need to generate large thrust, so the noise generated is also small and will not affect the newborn's normal sleep process.

[0020] 2. The neonatal nebulization therapy device of the present invention involves adding the medicine solution into the filling tank, closing the sealing cover, activating the electric telescopic rod to move the position of the moving seat vibration mesh, thereby moving the medicine solution. Excess air in the filling tank can directly pass through the vibration mesh, while the medicine solution, without the assistance of vibration, is difficult to pass through the fine mesh holes. This ensures that the medicine solution can pass through the vibration mesh constantly during the vibration nebulization process. Attached Figure Description

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1 to 7 As shown in the embodiment of the present invention, a neonatal nebulization therapy device includes a breathing mask 1, an nebulization box 5 is provided at the rear end of the breathing mask 1, the nebulization box 5 is connected to the breathing mask 1 through a connecting pipe 21, a vibrating mesh 24 capable of vibration is installed at the end of the connecting pipe 21 facing the nebulization box 5, a detachable power supply compartment 8 is provided at the bottom of the nebulization box 5, a power cord 11 is connected between the power supply compartment 8 and the nebulization box 5, two symmetrically arranged ventilation holes 2 are opened on the surface of the breathing mask 1, and multiple air ducts 4 with outward output ends are installed on the outer side of the breathing mask 1.

[0032] First, the medication is injected into the nebulizer box 5. The vibrating mesh 24 in the nebulizer box 5 atomizes the medication through vibration. The basic principle is: mechanical vibration generated by a high-frequency vibrator forces the medication through the tiny holes in the vibrating mesh 24, forming atomized particles. The resulting atomized particles are transferred to the breathing mask 1 via the connecting pipe 21. The breathing mask 1 is placed on the newborn's face, and multiple air blowers 4 are activated to generate airflow. This causes the air blowers 4 to generate thrust in the opposite direction. During nebulization treatment, the newborn will only lie down. To allow the newborn to breathe... The breathing mask 1 will not fall off. As long as the friction between the breathing mask 1 and the newborn's face is greater than the weight of the breathing mask 1, it will remain in close contact with the newborn's face. Through the separate design of the power compartment 8, it can be removed outwards, leaving only the atomizing box 5 and the breathing mask 1 on the face. The total weight of the two and their internal components does not exceed 100 grams. All components are made of lightweight materials, so the combined weight is 1N. The coefficient of friction between the breathing mask 1 and the face generally exceeds 0.5, therefore the pushing force generated by the multiple air ducts 4... A force of just over 2N is sufficient to ensure that the breathing mask 1 remains firmly in place on the newborn's face, even in a vertical position, such as when the newborn rolls over to sleep on their side. Simultaneously, the curved opening at the front of the breathing mask 1 allows it to receive support from multiple angles, further reducing the required thrust. When there are three air tubes 4, each only needs to generate a thrust of just over 0.4N to achieve the desired resultant force. Therefore, regardless of how the newborn rolls over, the thrust generated by the air tubes 4 on the breathing mask 1 is always directed towards it, preventing the mask from detaching from the newborn's face. This design allows the breathing mask 1 to remain in place on the newborn's face even without human intervention, while maintaining appropriate force to avoid causing excessive discomfort and increasing the newborn's willingness to undergo nebulization therapy. Furthermore, the nebulizer box 5 uses a mesh nebulizer design, resulting in extremely low noise. Since multiple air tubes 4 do not require significant thrust, the noise generated is also minimal and will not affect the newborn's normal sleep.

[0033] The number of air ducts 4 is three, two of which are located on both sides of the breathing mask 1 and are symmetrically arranged. The remaining air ducts 4 are located on the outer side and above the breathing mask 1. The outer side of each air duct 4 is provided with an air intake hole 20 for inhalation.

[0034] When in operation, the combined force of the three air blowers 4 is perpendicular to the newborn's face. Therefore, as long as the breathing mask 1 is placed in the correct position at the beginning, the breathing mask 1 can be guaranteed to fit the face. The air blower 4 is positioned around itself to ensure that the force generated by the inhalation does not affect the direction of the thrust. The combined position of the three air blowers 4 can better ensure that the combined force of the air blowers 4 is perpendicular to the newborn's face.

[0035] The top surface of the atomizing box 5 is provided with a filling groove 22 for filling liquid medicine. A movable seat 23 is provided inside the filling groove 22. The height and width of the movable seat 23 are the same as those of the filling groove 22. The movable seat 23 is located on the side away from the vibration net 24. An electric telescopic rod is fixedly connected inside the movable seat 23. The electric telescopic rod is fixedly connected to the inner wall of the atomizing box 5. A sealing cover 6 is rotatably connected to the top of the atomizing box 5.

[0036] During operation, the liquid medicine is added to the filling tank 22, the sealing cover 6 is closed, and the electric telescopic rod is activated to move the position of the moving seat 23 and the vibrating net 24, thereby moving the liquid medicine. Excess air in the filling tank 22 can pass directly through the vibrating net 24, while the liquid medicine is difficult to pass through the fine mesh without the assistance of vibration. This ensures that the liquid medicine can pass through the vibrating net 24 constantly during the vibration atomization process.

[0037] The rear end of the breathing mask 1 is fixedly connected to a sealing cover 18, and the connecting tube 21 passes through the sealing cover 18 and communicates with the interior of the breathing mask 1. Two guide tubes 3 are installed at the end of the connecting tube 21.

[0038] During operation, the guide tube 3 is designed to deliver the atomized medicine to the newborn's nose and mouth, so that the newborn can absorb more medicine vapor during inhalation. The ventilation hole 2 allows outside air to enter the breathing mask 1 normally and exchange with the air inside the breathing mask 1, ensuring normal oxygen absorption for the newborn.

[0039] The guide tube 3 is flat and a connecting valve tube 17 that communicates with the connecting tube 21 is fixed between the rear ends of the two guide tubes 3.

[0040] During operation, the nebulized medicine discharged from the flat guide tube 3 is more suitable for the shape of the newborn's nose and mouth absorption area. The connecting valve tube 17 can effectively distribute the nebulized medicine from the connecting tube 21 to the two guide tubes 3.

[0041] Multiple airflow detection modules 14 are installed at the end of the guide tube 3. The multiple airflow detection modules 14 are arranged linearly and equidistantly. An electromagnetic switching valve 16 is fixed between two guide tubes 3.

[0042] During operation, the airflow detection module 14 can use a hot-wire airflow sensor. The basic principle is that when airflow passes through the sensor, it carries away some of the heat from the hot wire, causing the temperature of the hot wire to drop. Since the resistance of the hot wire changes with temperature, this temperature change causes a change in the resistance of the hot wire, thereby detecting the airflow speed. When the newborn exhales through their mouth, the airflow detection module 14 can detect it. When the mesh nebulizer atomizes the medicine and finally discharges it from the guide tube 3, it is at room temperature and the speed is constant, so it will not affect the value of the airflow detection module 14. When the newborn inhales through their nose and exhales through their mouth, the electromagnetic switching valve 16 partially closes the guide tube 3 near the mouth, allowing the medicine to be discharged from the guide tube 3 near the nose. Conversely, the guide tube 3 near the nose is closed. This setting maximizes the absorption efficiency of the medicine. When exhaling through only the nose or mouth, the guide tube 3 is also partially closed. If the discharge of the medicine affects breathing, it will cause discomfort to the newborn or even choke the newborn. The medicine discharged from the other guide tube 3 will be mixed with air and normally inhaled by the newborn.

[0043] A compression ring 19 is fixed to the front edge of the breathing mask 1. The compression ring 19 is made of elastic material and the inside of the compression ring 19 is hollow. An absorption hole 12 is provided at the connection between the air duct 4 and the breathing mask 1.

[0044] When in operation, the pressure ring 19 provides a larger friction area and increases the coefficient of friction after contacting the newborn's face, thereby further ensuring the fit between the breathing mask 1 and the newborn's face. When it is necessary to increase the nebulization speed, the air intake end of the air duct 4 can be connected to the absorption hole 12, so that the air in the breathing mask 1 can be quickly exchanged with the outside air, without causing a large amount of liquid to fill and affect the newborn's breathing.

[0045] The top of the power compartment 8 is connected to the atomizing box 5 by a snap fastener. The top of the power compartment 8 has a storage slot, and the power cord 11 is arranged in a spiral shape and is located in the storage slot.

[0046] When in operation, the bottom of the power compartment 8 is separated from the atomizing box 5, while the power cord 11 remains connected for power transmission. The two can also be connected to each other. The power cord 11 can be stored in the storage slot for easy carrying of the device. At the same time, the device can also be used by hand.

[0047] An alarm 7 is installed on the top of the sealing cover 6, and observation windows 15 communicating with the filling groove 22 are provided on both sides of the atomizing box 5.

[0048] During operation, the observation window 15 is used to observe the amount of liquid in the atomizing box 5. The alarm 7 is triggered when the airflow detection module 14 shows abnormal data. The alarm can be an audible and visual alarm. When a cough occurs, the airflow suddenly increases. After the airflow detection module 14 detects this, it can promptly transmit the information to the alarm 7.

[0049] A fixing strip 9 is fixed to the outside of the power compartment 8. The fixing strip 9 is made of flexible material. A flexible magnetic sheet 10 is fixed to one end of the fixing strip 9. A magnetizable metal strip is provided inside the fixing strip 9.

[0050] During operation, the fixing strip 9 can be used to surround the item, and then the magnetic sheet 10 can be used to attach it to complete the fixation of the power compartment 8.

[0051] During operation, the breathing mask 1 is placed on the newborn's face. Multiple air blowers 4 are activated to generate outward airflow, causing the blowers 4 to push in the opposite direction. Since the newborn will only lie down during nebulization treatment, to prevent the breathing mask 1 from falling off, the friction between the breathing mask 1 and the newborn's face needs to be greater than the weight of the breathing mask 1. This will keep the breathing mask 1 in close contact with the newborn's face. Through the separate design of the power compartment 8, it can be removed outwards, leaving only the nebulizer box 5 and the breathing mask 1 on the face. The total weight of the two and internal parts does not exceed 100 grams. All parts are made of lightweight materials, so the combined weight is 1N. The coefficient of friction between the breathing mask 1 and the face generally exceeds 0.5, so the pushing force generated by the multiple air blowers 4 only needs to exceed 2N to ensure that the breathing mask 1 remains stably on the newborn's face even in a vertical position, such as when the newborn rolls over to sleep on their side. Simultaneously, the arc-shaped opening at the front of the breathing mask 1 allows the breathing mask 1 to be supported from multiple angles, further reducing the thrust requirement. When there are three air tubes 4, each air tube 4 only needs to generate a thrust of more than 0.4N, and the combined force can easily achieve the target. At this time, no matter how the newborn rolls over, because the thrust generated by the air tube 4 on the breathing mask 1 is always directed towards the breathing mask 1, the breathing mask 1 will not fall off the newborn's face. Through this setting, the breathing mask 1 can be kept on the newborn's face without human intervention, and the force is appropriate, so as not to make the newborn feel excessively uncomfortable, increasing the newborn's willingness to accept nebulization treatment. In addition, the nebulizer box 5 adopts a mesh nebulizer design, which produces extremely low noise, and multiple air tubes 4 do not need to generate a large thrust, so the noise produced is also small and will not affect the newborn's normal sleep process.

[0052] The combined force of the three air blowers 4 is perpendicular to the newborn's face. Therefore, as long as the breathing mask 1 is placed in the correct position, the breathing mask 1 will fit the face. The air blower 4 is positioned around itself to ensure that the force generated by the inhalation does not affect the direction of the thrust. The combination of the positions of the three air blowers 4 can better ensure that the combined force of the air blowers 4 is perpendicular to the newborn's face.

[0053] Add the liquid medicine to the filling tank 22, close the sealing cover 6, start the electric telescopic rod to push the moving seat 23 and the vibration net 24 to move, thereby pushing the liquid medicine to move. Excess air in the filling tank 22 can pass directly through the vibration net 24, while the liquid medicine is difficult to pass through the fine mesh without the assistance of vibration. This ensures that the liquid medicine can pass through the vibration net 24 constantly during the vibration atomization process.

[0054] The guide tube 3 is designed to deliver the atomized medicine to the newborn's nose and mouth, so that the newborn can absorb more medicine vapor during inhalation. The ventilation hole 2 allows outside air to enter the breathing mask 1 normally and exchange with the air inside the breathing mask 1, ensuring normal oxygen absorption for the newborn.

[0055] The flat guide tube 3 discharges atomized medicine that is more suitable for the shape of the newborn's nose and mouth absorption area. The connecting valve tube 17 can effectively distribute the atomized medicine from the connecting tube 21 to the two guide tubes 3.

[0056] The airflow detection module 14 can use a hot-wire airflow sensor. The basic principle is that when airflow passes through the sensor, it carries away some of the heat from the hot wire, causing the temperature of the hot wire to drop. Since the resistance of the hot wire changes with temperature, this temperature change causes a change in the resistance of the hot wire, thereby detecting the airflow speed. When the newborn exhales through his mouth, the airflow detection module 14 can detect it. When the mesh nebulizer atomizes the medicine and finally discharges it from the guide tube 3, it is at room temperature and the speed is constant, so it will not affect the value of the airflow detection module 14. When the newborn inhales through his nose and exhales through his mouth, the electromagnetic switching valve 16 partially closes the guide tube 3 near the mouth, allowing the medicine to be discharged from the guide tube 3 near the nose. Conversely, the guide tube 3 near the nose is closed. This setting can maximize the absorption efficiency of the medicine. When there is only one nose or mouth exhalation, the guide tube 3 is also partially closed directly. This is because if the discharge of the medicine affects breathing, it will cause discomfort to the newborn or even choke the newborn. The medicine discharged from the other guide tube 3 will be mixed with air and normally inhaled by the newborn.

[0057] After the pressure ring 19 comes into contact with the newborn's face, it will provide a larger friction area and increase the coefficient of friction, thereby further ensuring the fit between the breathing mask 1 and the newborn's face. When it is necessary to increase the nebulization speed, the air inlet of the air duct 4 can be connected to the absorption hole 12, so that the air in the breathing mask 1 can be quickly exchanged with the outside air, without causing a large amount of liquid to fill and affect the newborn's breathing.

[0058] Separate the bottom of the power compartment 8 from the atomizing box 5, while keeping the power cord 11 connected for power transmission. The two can also be connected to each other. The power cord 11 can be stored in the storage slot for easy carrying of the device. At the same time, the device can also be used by hand.

[0059] The observation window 15 is used to observe the amount of liquid in the atomizing box 5. The alarm 7 is used to sound an alarm when the airflow detection module 14 has abnormal data. The alarm can be an audible and visual alarm. When a cough occurs, the airflow suddenly increases. After the airflow detection module 14 detects this, it can promptly transmit the information to the alarm 7.

[0060] The fixing strip 9 can be used to wrap around the item, and then the magnetic sheet 10 can be used to attach it to complete the fixation of the power compartment 8.
