Description

Technical Field

[0001] The present invention relates to the field of nebulizers, and more particularly to a nebulizer for neonatal airway protection and atomization delivery. Background Art

[0002] In the clinical treatment of newborns, nebulization therapy is a commonly used and effective treatment method. It can atomize drugs into tiny particles so that the drugs can act directly on the respiratory tract, which is of great significance for the treatment of neonatal respiratory diseases.

[0003] In neonatal nebulization treatment, most existing masks are directly wrapped around the head with straps to facilitate fitting them to the neonatal face for nebulization treatment. However, neonates have poor autonomous awareness and are prone to tossing and turning during nebulization treatment, making it difficult for the mask to fit the neonatal face well during nebulization treatment, resulting in poor fit between the mask and the face, which not only affects the comfort of use, but also reduces the sealing, greatly reducing the effect of nebulization treatment. Moreover, when the mask is flipped off, the equipment cannot sense and handle this situation in time, which not only causes continuous waste of nebulized drugs, but also may pose potential risks to the neonate. Moreover, during use, when the delivery tube is bent, it is easy to cause unstable flow of nebulized drugs, making it difficult to ensure stable delivery, thereby affecting the stability and reliability of the treatment, and may prevent the neonate from obtaining sufficient nebulized drug dosage, delaying the treatment effect. Summary of the Invention

[0004] In view of the problems in the prior art that nebulizer masks are difficult to fit well, affecting comfort and sealing, and that the detachment of the mask cannot be detected and processed in time, resulting in waste of nebulized drugs and unstable delivery of nebulized drugs, the purpose of the present invention is to provide a nebulizer for neonatal airway protection and nebulization delivery.

The sealing is increased by the sealing card to achieve closed flow of nebulized drugs, stop the delivery of nebulized drugs in time, and avoid the waste caused by continuous delivery of nebulized drugs. When the pressure sensor senses that the newborn is about to choke during nebulization treatment, it can adaptively slow down the output of its nebulization flow, further increasing the comfort during nebulization treatment.

[0056] like Figures 1 to 8As shown, the embodiment of the present invention provides a nebulizer for neonatal airway protection and atomization delivery, including a nebulizer body 1. It should be noted that the nebulizer body 1, as the core part of the entire device, is responsible for atomizing the medicine into tiny particles, providing a basis for subsequent atomization delivery. A chamber specifically for storing medicine is provided inside the nebulizer body 1. The chamber is opened and closed by a sealing cover 3, and an ultrasonic transducer is installed inside. When the ultrasonic transducer is turned on during atomization, the piezoelectric material in the ultrasonic transducer produces an inverse piezoelectric effect under the action of electrical energy, that is, converting electrical energy into high-frequency mechanical vibration to generate ultrasonic waves. The ultrasonic transducer The high-frequency vibration generated by the device is transmitted to the surface of the liquid medicine in the medicine storage chamber through the oscillating diaphragm, causing the liquid to form tiny droplets, and under the action of ultrasonic waves, it continuously detaches from the liquid surface to form atomized particles and enters the medicine liquid storage chamber in the sealing cover 3, mixing with the atomized medicine particles. The mixed gas and medicine particles are transported to the atomization pipe 4 on the sealing cover 3 through the mist outlet channel, and then enter the subsequent atomization delivery system. Since the atomization method adopted by the atomizer body 1 is already a well-known prior art in this field, in order to avoid unnecessary repetition, the specific atomization structure inside it is not disclosed in detail. In addition, this atomization method is widely present in many fields, only including and not unique, and will not be further elaborated here.

[0057] The nebulizer body 1 is equipped with an alarm 2, which can sound an alarm when the newborn's face is separated from the mask and causes mist leakage, close the mist delivery channel, and remind medical staff to deal with it in time to ensure the safety of the newborn and avoid waste of liquid medicine. The nebulizer body 1 is clamped with a sealing cover 3, and the sealing cover 3 is connected to a mist outlet pipe 4, which is a transmission channel for atomized medicine. The top surface of the mist outlet pipe 4 is rotatably connected to a turntable 5. In order to ensure stable delivery of the flow rate of atomized medicine when the subsequent pipeline is bent, a mounting bracket 41 is coaxially fixedly sleeved on the mist outlet pipe 4, and the upper end of the mounting bracket 41 is fixedly connected to a connecting pipe 9. The turntable 5 is connected to the connecting pipe 9 is rotatably connected. A plurality of rotating rods 6 are rotatably connected in the turntable 5. A fan-shaped baffle 62 is fixedly sleeved on the plurality of rotating rods 6. The rotating rods 6 and the fan-shaped baffle 62 are arranged in a circular array. The fan-shaped baffle 62 is rotated by rotating the rotating rod 6. The function of the fan-shaped baffle 62 is to control the flow rate of the atomized medicine. When the fan-shaped baffle 62 is rotated to different positions, it will block different areas of the mist outlet pipe 4, thereby realizing the regulation of the flow rate of the atomized medicine. One end of the rotating rod 6 located in the turntable 5 is rotatably connected to a connecting rod 61. The plurality of rotating rods 6 are rotatably connected to the connecting rod 61, so that the plurality of rotating rods 6 can rotate in coordination, thereby ensuring the stability and consistency of the flow rate regulation.

[0058] A corrugated tube 91 is fixedly connected to the mounting frame 41, and the connecting tube 9 rotates around the outer wall of the corrugated tube 91. The corrugated tube 91 has good flexibility and bendability, and can be easily bent and adjusted in position without affecting the delivery of aerosolized drugs, so as to adapt to the different postures and positions of the newborn during treatment, and reduce problems such as blockage or poor airflow caused by rigid bending of the tube. The end of the corrugated tube 91 is connected to a transfer tube 10, which plays a role of transition and transfer, and further transmits the aerosolized drug delivered by the corrugated tube 91 to the mask shell 12. A buffer plug valve 11 is installed on the transfer tube 10, which can buffer the airflow pressure of the aerosolized drug to a certain extent, prevent excessive airflow pressure from causing impact and damage to the airway of the newborn, and keep the airflow pressure of the aerosolized drug entering the airway of the newborn within a safe and appropriate range, so that the gas flow state can be stabilized, thereby ensuring that the mist can be delivered continuously and stably. In this way, even if the corrugated conduit 91 bends during use, it can effectively avoid adverse effects on the stable delivery of the mist flow.

[0059] The end side of the transfer tube 10 is connected to a mask shell 12, which provides a space for installing and protecting the airbag mask 13. An inflatable airbag mask 13 is installed in the mask shell 12. The inflatable property of the airbag mask 13 enables it to better fit the face of the newborn, forming a relatively closed space, improving the effect of atomization treatment, and reducing the leakage of drugs to avoid pollution to the surrounding environment. The good fit between the airbag mask 13 and the newborn's face can also prevent the aerosolized medicine from entering the newborn's eyes and other sensitive parts, protecting the safety of the newborn. A pressure sensor 14 is fixed in the airbag mask 13, and the pressure sensor 14 is electrically connected to the alarm 2 and the electromagnet. The model of the pressure sensor 14 is MEAS-1210A. The pressure sensor 14 can monitor the pressure inside the airbag mask 13 in real time. When the newborn moves around during the aerosolization process and causes the airbag mask 13 to detach, the pressure sensor 14 will sense it and transmit the signal to the alarm 2, motor 631 and electromagnet. The alarm 2 will sound an alarm to remind medical staff to adjust and automatically shut down the mist delivery in time to avoid waste.

[0060] like Figure 2 and Figure 5As shown, the embodiment of the present invention also includes a rotating component 63 and a limiting component, the rotating component 63 is convenient for synchronously driving multiple rotating rods 6 and fan-shaped blocking plates 62 to rotate synchronously, the rotating component 63 includes a motor 631, the motor 631 is fixed on the mist outlet pipe 4, the motor 631 is electrically connected to the alarm 2, when it is detected that the newborn's face is out of the airbag mask 13, the pressure sensor 14 promptly transmits a signal to the alarm 2 to sound an alarm, the motor 631 can then take corresponding actions according to the signal of the alarm 2, such as stopping rotation or adjusting the speed, thereby stopping or adjusting the flow rate of the atomized medicine in time to avoid waste of liquid medicine and unnecessary effects on the newborn, the output end of the motor 631 is fixedly connected to a coupling 632, the end of the coupling 632 is fixedly connected to a gear 633, a collar 634 is coaxially connected to the turntable 5, the outer wall of the turntable 5 is provided with a slide groove that facilitates the rotation of the collar 634, so that the collar 63 4 can be flexibly rotated on the turntable 5, and the slide groove plays a certain guiding and limiting role on the ring 634 to ensure the stability of the rotation of the ring 634. The outer wall of the ring 634 is fixedly connected to the ring gear 635, and the outer wall of the ring 634 is fixedly connected to a plurality of protruding rods 636. A crank 637 is installed on each of the plurality of protruding rods 636. The protruding rods 636 are slidably connected to the crank 637. When the motor 631 drives the gear 633 to rotate, the gear 633 and the ring gear 635 are connected. The engagement of the collar 634 with the crank 637 transmits power to the collar 634, causing the collar 634 to rotate accordingly. As the collar 634 rotates, the protruding rod 636 moves in a circular motion along with the collar 634. The crank 637 is made of a rigid material and has an annular groove therein for facilitating the sliding of the protruding rod 636. The rotating rod 6 is fixedly connected to the crank 637. When the collar 634 rotates, the protruding rod 636 slides within the annular groove of the crank 637, thereby driving the rotation of the crank 637. Because the crank 637 is fixedly connected to the rotating rod 6, the synchronous rotation of multiple rotating rods 6 is achieved. This structural design cleverly converts the circular motion of the collar 634 into the rotation of the rotating rod 6, ensuring the synchronous movement of the multiple rotating rods 6 and the fan-shaped baffle 62, thereby precisely controlling the flow rate of the aerosolized drug.

[0061] The limiting assembly includes a first limiting member 7 and a second limiting member 8 . The first limiting member 7 is used to limit the rotation of the rotating rod 6 , and the second limiting member 8 is used to limit the rotation of the rotating disk 5 .

[0062] Specifically, such as Figure 5As shown, the first limiting member 7 includes a first groove 71 opened inside the turntable 5, the opening of the first groove 71 faces the top surface of the ring 634, the inner wall of the first groove 71 is fixedly connected to a first electromagnet 72, the first electromagnet 72 is fixedly connected to a first spring 73, the other end of the first spring 73 is installed with a first permanent magnet 74, and the first permanent magnet 74 is fixedly connected to a first brake pad 75.

[0063] The second limiting member 8 includes a second groove 81 opened on the top surface of the turntable 5, and the inner wall of the second groove 81 is fixedly connected to a second electromagnet 82, and the second electromagnet 82 is fixedly connected to a second spring 83. The other end of the second spring 83 is installed with a second permanent magnet 84, and the second permanent magnet 84 is fixedly connected to a second brake pad 85.

[0064] The function of the first spring 73 and the second spring 83 is to provide elastic force for the first permanent magnet 74 and the second permanent magnet 84 to keep them in their initial positions when the first electromagnet 72 and the second electromagnet 82 are not energized. When the first electromagnet 72 or the second electromagnet 82 is energized to generate a magnetic field, the magnetic field will attract or repel the first permanent magnet 74 and the second permanent magnet 84, thereby moving the first brake pad 75 or the second brake pad 85. By controlling the energized state of the first electromagnet 72 and the second electromagnet 82, the first brake pad 75, the second brake pad 85 can be fitted into or separated from the collar 634 or the connecting tube 9, thereby achieving the purpose of limiting rotation.

[0065] During the operation of the equipment, once the corrugated conduit 91 is bent, in order to avoid unstable flow delivery caused by the bending, it is necessary to drive the turntable 5 to rotate, such as Figure 5The figure shows the initial position state of the first brake pad 75 and the second brake pad 85. The second electromagnet 82 is energized to generate a magnetic force to attract the second permanent magnet 84. The second permanent magnet 84 is forced to drive the second brake pad 85 downward, and the connecting tube 9 is separated from the second brake pad 85. At this time, the restriction relationship between the turntable 5 and the connecting tube 9 is released, and relative rotation can be generated. The first electromagnet 72 is energized again to generate a repulsive force acting on the first permanent magnet 74. The first permanent magnet 74 drives the first brake pad 75 downward, so that it fits tightly with the surface of the collar 634, and relies on friction to prevent the collar 634 from rotating. At this time, the first limit member 7 and the second limit member 8 are coordinated to form a whole, so that the turntable 5, the collar 634 and the connecting tube 9 are formed into a whole. Due to the meshing of the gear 633 and the ring gear 635, the motor 631 is started to drive the coupling 632 upward. The gear 633 applies force to the ring gear 635, so that the whole formed by the turntable 5, the collar 634 and the connecting tube 9 rotates in the mounting frame 41, and the connecting tube 9 rotates around the corrugated tube 91. Since the turntable 5, the collar 634 and the connecting tube 9 form a whole, during the rotation process, the crank 637 and the rotating rod 6 rotate synchronously, so the crank 637 does not apply pressure to the rotating rod 6, and the rotating rod 6 does not rotate, and finally the fan-shaped baffle 62 is at a relatively fixed angle. Since the fan-shaped baffle 62 is at a relatively fixed angle, when the turntable 5, the collar 634 and the connecting tube 9 form a whole and start to rotate, under the action of the fan-shaped baffle 62, the suction effect of the atomized drug is realized, so as to increase the flow rate of the atomized drug, prevent the drug from gathering in one place, realize stable delivery, and effectively avoid the influence of the bending of the corrugated tube 91 on the stability of the atomized drug delivery.

[0066] During the operation of the equipment, when it is necessary to control the flow of the atomized medicine, the first electromagnet 72 and the second electromagnet 82 are de-energized at the same time. At this time, the first spring 73, by virtue of its elastic properties, drives the first permanent magnet 74 and the first brake pad 75 to reset upward, so that they are separated from the top surface of the ring 634, and the restriction on the rotation of the ring 634 is released. The second spring 83, by virtue of its elastic properties, drives the second permanent magnet 84 and the second brake pad 85 to reset upward, so that they are against the bottom surface of the connecting tube 9, and restore the restriction between the turntable 5 and the connecting tube 9.

[0067] Then the motor 631 is started to drive the coupling 632 to drive the gear 633 to rotate. Since the gear 633 and the ring gear 635 are meshed with each other, the coupling 632 will drive the ring gear 635 to rotate through the meshing action during the process of driving the gear 633 to rotate. Since the collar 634 and the ring gear 635 are fixed, the collar 634 will be forced to rotate in the slide groove of the turntable 5 as the ring gear 635 rotates. Since multiple protrusions 636 are fixed on the collar 634, when the collar 634 rotates, During the rotation process, the multiple protruding rods 636 on the outer wall will also rotate synchronously with the rotation trajectory of the collar 634. During this rotation process, since the crank 637 has an annular groove and the crank 637 is sleeved on the protruding rod 636, the protruding rod 636 will slide in the annular groove during the rotation process. Since the protruding rod 636 is restricted in the annular groove, a thrust will be generated on the crank 637 during the rotation process of the protruding rod 636. The crank 637 will swing under the action of the thrust. During the swing process of the crank 637, since the rotating rod 6 and the crank 637 are fixed, the rotating rod 637 will not be rotated. The crank 637 is fixedly connected, so the rotating rod 6 will swing synchronously during the swinging process of the crank 637. Since the rotating rod 6 is rotationally connected to the turntable 5, the thrust of the swinging of the rotating rod 6 will be converted into a circular motion, so that the rotating rod 6 rotates in the turntable 5, thereby realizing the synchronous rotation of multiple rotating rods 6, thereby driving the collar 634 to rotate in the sliding groove in the turntable 5, and the multiple protruding rods 636 on the outer wall of the collar 634 are also subjected to force and slide in the annular groove of the crank 637, so that the multiple cranks 637 are forced to rotate, thereby driving the multiple rotating rods 6 to rotate synchronously. When the rod 6 rotates, since the fan-shaped baffle 62 is fixedly connected to the rotating rod 6, and the number of the fan-shaped baffles 62 corresponds to the setting of the rotating rod 6, the multiple fan-shaped baffles 62 will also rotate synchronously with the multiple rotating rods 6. When the fan-shaped baffle 62 rotates, the blocking state of the fan-shaped baffle 62 will be adjusted. By adjusting the flipping angle between the multiple fan-shaped baffles 62, the flow rate of the delivered medicine can be adjusted, and then the flow rate of the nebulized medicine can be controlled according to demand, so as to stop or adjust the flow rate of the nebulized medicine in time to avoid waste of medicine and unnecessary impact on the newborn.

[0068] When the airbag mask 13 is in a disengaged state during use, the above-mentioned setting can be used to flip the fan-shaped baffle 62 to a suitable angle and achieve complete closure, so as to prevent the aerosolized medicine from continuing to escape outward, causing drug waste or personal injury to other surrounding personnel. The first limit member 7 and the second limit member 8 cooperate with each other, so that the rotation of the turntable 5, the ring 634, the rotating rod 6, and the fan-shaped baffle 62 can be accurately limited according to different working requirements, ensuring that the equipment can maintain good stability in different working stages.

[0069] like Figure 6 and Figure 7 As shown, the embodiment of the present invention also includes an expansion assembly that facilitates inflation of the airbag-mask 13. The expansion assembly includes a notch 121 symmetrically arranged on the mask shell 12. An elastic band 122 is inserted into the notch 121, providing space for the elastic band 122 to pass through, ensuring that the elastic band 122 is evenly distributed around the mask shell 12, thereby providing balanced tension when securing the mask. The shape and size of the notch 121 are compatible with the elastic band 122, ensuring smooth insertion of the elastic band 122 while preventing it from easily slipping out during use. The elastic band 122 is secured by Velcro, with the hooks on the hook surface intertwined with the velvet on the fleece surface. By adjusting the degree of stretching of the elastic band 122, the tightness of the Velcro fit can be varied to accommodate the size and shape of different newborn heads, helping to more securely secure the airbag-mask 13 to the newborn's face. After the treatment, you only need to gently pull the elastic strap 122 to separate the hook surface and the fleece surface, and then you can easily remove the elastic strap 122 and the mask. The elastic properties of the elastic strap 122 can also reduce the pressure on the newborn's skin to a certain extent and improve the wearing comfort.

[0070] Through holes 123 are formed in the sidewalls of both the mask shell 12 and the airbag mask 13, ensuring a tight connection between the air intake pipe 124 and the mask shell 12, preventing gas leakage. The air intake pipe 124 is connected to the through hole 123 in the airbag mask 13. A screw 125 is rotatably connected to the sidewall of the air intake pipe 124. A slide rod 126 is threadedly connected to the end of the screw 125. A piston 127 is fixed to the bottom of the slide rod 126. The piston 127 promotes the flow of gas within the air intake pipe 124. When the slide rod 126 moves axially along the air intake pipe 124 under the action of the screw 125, the piston 127 moves with it, compressing the air within the air intake pipe 124 and pushing it toward the airbag mask 13, completing the inflation process. The piston 127 also provides a good seal, effectively preventing gas leakage within the air intake pipe 124 and ensuring the efficiency and effectiveness of the inflation process.

[0071] The air intake pipe 124 is embedded and fixed in the through hole 123 on the mask shell 12, the outer contour of the piston 127 fits the inner contour of the air intake pipe 124, and the through hole 123 on the airbag mask 13 is directly connected to the air intake pipe 124, so that the gas entering from the air intake pipe 124 can flow smoothly into the interior of the airbag mask 13.

[0072] The interior of the airbag mask 13 is hollow, and the fitting surface of the airbag mask 13 is semi-arc-shaped, which provides space for storing and filling gas. When the airbag mask 13 is inflated through the expansion component, the gas can be evenly distributed in the hollow part, so that the airbag mask 13 is evenly expanded, thereby closely fitting the facial contour of the newborn.

[0073] The workflow of the technical solution provided by the present invention is as follows:

[0074] When in use, the elastic strap 122 is passed through the two notches 121 of the mask shell 12 and fixed by Velcro, and then put on the head of the newborn. At this time, the airbag mask 13 is initially fitted to the newborn's face, and then the screw 125 on the side wall of the air inlet pipe 124 is rotated. When the screw 125 rotates, the slide rod 126 threadedly connected thereto will move along the axis of the screw 125, and the piston 127 at its bottom will move with the slide rod 126. The piston 127 is forced to move in the air inlet pipe 124, and then the air is pressed into the airbag mask 13 through the air inlet pipe 124. As the air continues to enter, the gas inside the airbag mask 13 increases, the pressure increases, and thus expansion is achieved. The fitting surface of the airbag mask 13 is set as a semi-arc surface, which can better fit the face of the newborn.

[0075] After the airbag mask 13 is worn, the device is turned on, and the nebulizer body 1 atomizes the medicine into tiny particles. The atomized medicine flows along the mist outlet pipe 4 into the connecting pipe 9, the corrugated conduit 91 and is sent into the airbag mask 13. During the operation of the device, when the corrugated conduit 91 is bent, in order to avoid unstable flow delivery caused by bending, it is necessary to drive the turntable 5 to rotate, and energize the second electromagnet 82 to generate magnetic force to attract the second permanent magnet 84. The second permanent magnet 84 is forced to drive the second brake pad 85 downward, and the connecting pipe 9 is separated from the second brake pad 85. At this time, the turntable 5 and the connecting pipe 9 can rotate relative to each other, and then the first electromagnet 72 is energized to generate a repulsive force acting on the first permanent magnet 74. The first permanent magnet 74 The first brake pad 75 is driven to move downward so that it fits tightly with the surface of the collar 634, and the collar 634 is prevented from rotating by friction. Then the motor 631 is started to drive the gear 633 on the coupling 632 to apply force to the ring gear 635, so that the whole formed by the turntable 5, the collar 634 and the connecting pipe 9 rotates in the mounting bracket 41, and the connecting pipe 9 rotates around the corrugated conduit 91, realizing the suction effect of the atomized medicine to increase the flow rate of the atomized medicine and achieve stable delivery. In this process, the internal buffer plug valve 11 can buffer the airflow pressure of the atomized medicine to a certain extent, so that the medicine is slowly gathered in the mask shell 12 and the airbag mask 13, avoiding the discomfort of coughing caused by the newborn inhaling too quickly.

[0076] When the flow rate of the atomized medicine needs to be controlled, the first electromagnet 72 and the second electromagnet 82 are powered off at the same time. At this time, the first spring 73, by virtue of its elasticity, drives the first permanent magnet 74 and the first brake pad 75 to reset upward, so that they are separated from the top surface of the collar 634, thereby releasing the restriction on the rotation of the collar 634. The second spring 83, by virtue of its elasticity, drives the second permanent magnet 84 and the second brake pad 85 to reset upward, so that they are against the bottom surface of the connecting tube 9, thereby restoring the restriction between the turntable 5 and the connecting tube 9, and then starts the power. The machine 631 drives the coupling 632 to drive the gear 633 to rotate. Since the gear 633 is engaged with the ring gear 635, it drives the ring 634 to rotate in the slide groove in the turntable 5. The multiple protrusions 636 on the outer wall of the ring 634 are also subjected to force and slide in the annular groove of the crank 637, causing the multiple cranks 637 to rotate under force, thereby driving the multiple rotating rods 6 to rotate synchronously. The fan-shaped baffle 62 will also rotate synchronously with the multiple rotating rods 6, so that the flipping angle of the fan-shaped baffle 62 can be adjusted to control the flow rate of the atomized medicine.

[0077] During the nebulization treatment of newborns, due to the active nature of the newborn, the newborn may flip over during the nebulization, causing the airbag mask 13 to accidentally detach. When this happens, the pressure sensor 14 will immediately sense the change and quickly transmit the received electrical signal to the motor 631, the electromagnet and the alarm 2. The alarm 2 will then sound a loud alarm to remind medical staff to deal with it in time. At the same time, the fan-shaped baffle 62 can be flipped to a suitable angle and completely closed through the above-mentioned setting to prevent the nebulized drug from continuing to escape outward and causing drug waste or personal injury to other surrounding people. The sealing of the card plate 621 is further enhanced. In this way, the nebulized drug can be effectively closed, the delivery of the nebulized drug can be stopped in time, and unnecessary waste caused by the continuous delivery of the nebulized drug can be avoided.
