Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically referring to a nebulized treatment device for pediatric pneumonia. Background Technology

[0002] Nebulized therapy, which can transform drugs into fine particles that act directly on the respiratory tract and lung lesions, has advantages such as rapid onset of action, few side effects, and convenient administration, and has become one of the core methods for the clinical treatment of pediatric pneumonia.

[0003] Existing devices suffer from poor respiratory linkage adaptability, continuous nebulization leading to drug waste and easy resistance in children, and manual control increasing the nursing burden; unreasonable nebulization structure design, with inconsistent particle size or serious drug residue, affecting the treatment effect; cumbersome component connection and drug injection process, lack of convenient fixing structure, and insufficient treatment stability. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a nebulized treatment device for pediatric pneumonia, which effectively solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a nebulization treatment device for pediatric pneumonia, including a shell, an air-sealing plate, an air guide cylinder, a piston, and a nebulizing cylinder. The air-sealing plate and the air guide cylinder are disposed inside the shell. The air guide cylinder is located below the air-sealing plate. The piston is disposed inside the air guide cylinder. The air-sealing plate is connected to the piston. The nebulizing cylinder is disposed at the bottom of the air guide cylinder and is located inside the shell.

[0006] Furthermore, the housing has an air chamber at its center, an air outlet pipe on one side of the housing, a handle on the other side of the housing, the air outlet pipe connecting to the air chamber, a top through groove at the top of the housing, a bottom through hole at the bottom of the housing, and a face mask connected to the air outlet pipe.

[0007] Furthermore, the rear wall of the air chamber is provided with a side passage groove, the bottom of the air chamber is provided with a bottom passage pipe, rotating seats are symmetrically provided on both sides of the side passage groove, the air-sealing plate is rotatably mounted on the rotating seat, and the air guide tube is inserted into the bottom passage pipe.

[0008] Preferably, the housing incorporates an air chamber, a rotating base, and a bottom through-tube, precisely accommodating core components such as the air-sealing plate and air guide tube. This ensures stable assembly of all components, prevents displacement during use, and guarantees the stability of equipment operation. The top and side through-slots form an airflow channel, allowing for rapid replenishment of fresh air during inhalation and thorough mixing with the nebulized medication, ensuring smooth breathing for the child. The bottom through-hole precisely matches the installation path of the nebulizer cartridge, resulting in a compact pipe connection and reducing airflow leakage.

[0009] Furthermore, the air-sealing plate is symmetrically provided with rotating columns on its sidewalls, which divide the air-sealing plate into an upper rotating plate and a lower rotating plate. The lower rotating plate is located in the side passage groove and at the bottom of the air chamber.

[0010] Furthermore, one side of the lower rotating plate is provided with a lever and a baffle. The lever is located at the bottom of the lower rotating plate, and the other side of the lower rotating plate is provided with a return spring. The end of the return spring is attached to the inner wall of the housing. The baffle is attached to the bottom of the air chamber, and the lever is located on both sides of the air guide tube.

[0011] Preferably, the air-closing plate features a dual-plate design: an upper plate senses the negative pressure in the air chamber, while a lower plate drives a lever. This achieves a synchronized effect of "inhalation triggering airflow opening and exhalation automatically closing," eliminating the need for active operation by children. It perfectly matches the respiratory rhythm of pediatric patients, lowering the barrier to use. The return spring provides rapid elasticity, quickly pushing the air-closing plate back to its original position during exhalation. The baffle fits tightly against the bottom of the air chamber, preventing exhaled air from contaminating the interior and avoiding backflow of nebulized medication, thus ensuring treatment hygiene and drug utilization.

[0012] Furthermore, the top of the air guide cylinder is provided with a top through hole, the inner wall of the air guide cylinder is symmetrically provided with inner sliding grooves, the outer wall of the air guide cylinder is symmetrically provided with outer sliding grooves, and the outer sliding grooves are connected to the inner sliding grooves.

[0013] Furthermore, the outer wall of the air guide cylinder is also provided with a positioning baffle one and a positioning baffle two. The positioning baffle two is located below the positioning baffle one and at the bottom of the outer sliding groove. The positioning baffle one is attached to the bottom of the bottom passage pipe.

[0014] Preferably, the inner groove of the air guide tube is connected to the outer groove of the outer wall, providing a stable sliding track for the side support plate of the piston component, ensuring that the sealing plate is accurately aligned with the top through hole switch, and the operation is smooth without jamming; the positioning baffle one and positioning baffle two are respectively fitted and positioned with the bottom through pipe and the atomizing cylinder, requiring no additional calibration during installation, and the connection is firm and reliable, preventing airflow leakage.

[0015] Furthermore, the piston component has a sealing plate at its center, side support plates on both sides of the sealing plate, a side cross plate at the bottom of the side support plate, the sealing plate is located in the top through hole, the side support plate slides in the inner and outer sliding grooves, the side cross plate is located in the outer sliding groove, and the lever is attached to the top of the side cross plate.

[0016] Furthermore, the top of the atomizing cylinder is inserted into the bottom of the air guide cylinder, the second positioning baffle is attached to the top of the atomizing cylinder, the atomizing cylinder has a medicine storage tank in the center, and the medicine storage tank has a conical air pipe in the center.

[0017] Furthermore, the conical vent pipe is provided with water suction pipes on both sides, the water suction pipe is provided with a water inlet at the bottom, the conical vent pipe is provided with a partition at the top, the atomizing cylinder is provided with a connecting pipe at the bottom, the bottom of the atomizing cylinder passes through the bottom through hole, and the bottom of the connecting pipe is connected to a flexible tube.

[0018] Preferably, the conical ventilation tube design of the nebulizer creates a strong negative pressure when the airflow passes through at high speed, which can efficiently adsorb the drug in the drug storage tank; the water inlet at the bottom of the suction tube ensures that the drug is fully inhaled and avoids residue (especially suitable for pediatric drug dosage scenarios, reducing waste); the septum can separate the airflow and the drug, making the atomized particles fine and uniform, conforming to the physiological structure of children's respiratory tract, and able to directly reach the lung lesions, improving the treatment effect.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows: 1. Highly adaptable to pediatric conditions, conforming to children's breathing rhythm, adopting an automated linkage design of "inhalation trigger, exhalation closure". The air chamber negative pressure is sensed by the air closure plate, and the airflow channel can be automatically opened and closed without the child's active operation, perfectly matching the child's breathing rate; the mask conforms to the contour of the child's mouth and nose, the material is soft and skin-friendly, comfortable to wear without pressure, and has a reserved exhaust channel to avoid breathing suffocation and reduce children's resistance.

[0020] 2. High nebulization efficiency and outstanding therapeutic effect: The conical air tube of the nebulizer creates a strong negative pressure adsorption effect. Combined with the design of the water tube and the partition, the drug nebulization particles are fine and uniform, which fits the physiological structure of children's respiratory tract and can directly reach the lung lesions. When exhaling, the sealing plate closes the air delivery tube channel and the baffle closes the air chamber, which not only prevents the loss and waste of nebulized drugs, but also avoids the contamination of the device by exhaled gas, thus improving the drug utilization rate.

[0025] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] like Figures 1-11As shown, the present invention proposes a nebulization treatment device for pediatric pneumonia, including a housing 1, an air-sealing plate 2, an air guide cylinder 3, a piston 4, and a nebulizing cylinder 5. The air-sealing plate 2 and the air guide cylinder 3 are disposed inside the housing 1, with the air guide cylinder 3 located below the air-sealing plate 2. The piston 4 is disposed inside the air guide cylinder 3, and the air-sealing plate 2 is connected to the piston 4. The nebulizing cylinder 5 is disposed at the bottom of the air guide cylinder 3 and is located inside the housing 1.

[0027] The shell 1 has an air chamber 11 at its center, an air outlet pipe 12 on one side of the shell 1, a handle 14 on the other side of the shell 1, the air outlet pipe 12 is connected to the air chamber 11, the top of the shell 1 has a top through groove 13, the bottom of the shell 1 has a bottom through hole 15, and a mask 7 is connected to the air outlet pipe 12.

[0028] The rear wall of the air chamber 11 is provided with a side passage groove 111, the bottom of the air chamber 11 is provided with a bottom passage pipe 112, and rotating seats 113 are symmetrically provided on both sides of the side passage groove 111. The air-sealing plate 2 is rotatably mounted on the rotating seat 113, and the air guide tube 3 is inserted into the bottom passage pipe 112.

[0029] The air-tight plate 2 has symmetrical rotating columns 21 on its side wall. The rotating columns 21 divide the air-tight plate 2 into an upper rotating plate 22 and a lower rotating plate 23. The lower rotating plate 23 is located in the side passage groove 111 and at the bottom of the air chamber 11.

[0030] One side of the lower rotating plate 23 is provided with a lever 24 and a baffle 26. The lever 24 is located at the bottom of the lower rotating plate 23. The other side of the lower rotating plate 23 is provided with a return spring 25. The end of the return spring 25 is attached to the inner wall of the housing 1. The baffle 26 is attached to the bottom of the air chamber 11. The lever 24 is located on both sides of the air guide tube 3.

[0031] The top of the air guide cylinder 3 is provided with a top through hole 31, the inner wall of the air guide cylinder 3 is provided with an inner sliding groove 32 symmetrically, and the outer wall of the air guide cylinder 3 is provided with an outer sliding groove 33 symmetrically, and the outer sliding groove 33 is connected to the inner sliding groove 32.

[0032] The outer wall of the air guide tube 3 is also provided with positioning baffle 1 34 and positioning baffle 2 35. Positioning baffle 2 35 is located below positioning baffle 1 34 and is located at the bottom of the outer sliding groove 33. Positioning baffle 1 34 is attached to the bottom of the bottom through pipe 112.

[0033] Piston 4 has a sealing plate 41 at its center, side support plates 42 on both sides of the sealing plate 41, and a side horizontal plate 43 at the bottom of the side support plate 42. The sealing plate 41 is located in the top through hole 31. The side support plate 42 slides in the inner slide groove 32 and the outer slide groove 33. The side horizontal plate 43 is located in the outer slide groove 33. The lever 24 is attached to the top of the side horizontal plate 43.

[0034] The top of the atomizing cylinder 5 is inserted into the bottom of the air guide cylinder 3, and the positioning baffle 2 35 is attached to the top of the atomizing cylinder 5. The atomizing cylinder 5 has a medicine storage tank 51 in the center, and a conical air passage 52 is located in the center of the medicine storage tank 51.

[0035] The conical air pipe 52 is provided with water suction pipes 53 on both sides, and the bottom of the water suction pipe 53 is provided with a water inlet hole 54. The top of the conical air pipe 52 is provided with a partition 55, and the bottom of the atomizing cylinder 5 is provided with a connecting pipe 56. The bottom of the atomizing cylinder 5 passes through the bottom through hole 15, and the bottom of the connecting pipe 56 is connected to a flexible hose 6.

[0036] In practical use, disassemble the connection between the nebulizer 5 and the air delivery tube 3, inject an appropriate amount of pediatric pneumonia treatment medication into the medication reservoir 51, ensuring that the medication level does not exceed 2 / 3 of the reservoir's volume. Reconnect the top of the nebulizer 5 to the bottom of the air delivery tube 3, ensuring that the positioning flange 35 fits tightly against the top of the nebulizer 5 to guarantee a seal. Securely connect one end of the flexible hose 6 to the connecting pipe 56 at the bottom of the nebulizer 5, and connect the other end to the output end of an air pump that meets pediatric usage standards. Check that the tubing is undamaged and leak-free.

[0037] Medical staff or parents hold the handles 14 on both sides of the casing 1 and fix the device in a position that is convenient for the patient to breathe. They then put the mask 7 on the patient, ensuring that the mask 7 fits tightly against the patient's mouth and nose to avoid air leakage that could affect the nebulization effect.

[0038] When the child actively inhales through the mask 7, a negative pressure is created inside the air chamber 11, causing the upper rotating plate 22 of the air-sealing plate 2 to be drawn into the air chamber 11, making the air-sealing plate 2 rotate clockwise around the rotating column 21 on the rotating seat 113. At this time, the lower rotating plate 23 rotates synchronously and squeezes the return spring 25, and the lever 24 at its bottom presses down, pushing the side horizontal plate 43 to slide down along the outer sliding groove 33 of the air guide cylinder 3, and the side support plate 42 moves down synchronously along the inner sliding groove 32, finally causing the sealing plate 41 to disengage from the top through hole 31 of the air guide cylinder 3, opening the airflow channel.

[0039] The airflow from the air pump enters the conical ventilation tube 52 of the nebulizer 5 through the hose 6 and connecting pipe 56, and forms a negative pressure adsorption effect by flowing at high speed inside the tube. The medicine in the drug storage tank 51 is drawn into the water inlet 53 through the water inlet 54 at the bottom of the water inlet 53. It meets the high-speed airflow at the top of the conical ventilation tube 52, and is atomized into fine particles after being split by the partition 55. The atomized drug particles enter the air chamber 11 through the top through-hole 31. At the same time, external air enters the air chamber 11 through the top through-slot 13 and side through-slot 111 of the shell 1. After being fully mixed with the atomized medicine, it is inhaled into the respiratory tract by the child through the air outlet 12 and the mask 7, directly reaching the lung lesions.

[0040] When the child exhales, the air pressure inside the mask 7 and tubing increases, and the negative pressure in the air chamber 11 disappears. The return spring 25 returns to its original shape, pushing the air-sealing plate 2 to rotate counterclockwise around the rotating column 21 to reset. The baffle 26 re-fits the side passage groove of the air chamber 11, sealing the air chamber channel. At the same time, the lever 24 moves upward with the air-sealing plate 2, the side horizontal plate 43 loses pressure, and the airflow in the nebulizer 5 pushes the sealing plate 41 upward, re-embedding it into the top passage 31, sealing the airflow channel of the air guide tube 3, preventing the backflow or waste of uninhaled nebulized medicine, and ensuring that the exhaled air can only be discharged from both sides of the mask 7, avoiding contamination of the inside of the air chamber 11.

[0041] During treatment, the child's condition must be closely monitored to ensure stable breathing and that the mask does not shift. If the child coughs or cries, treatment should be paused until the child's mood stabilizes before resuming. Simultaneously, monitor the remaining nebulized medication. If the medication reservoir 51 is less than 1 / 5 full, the device should be paused, the medication replenished, and treatment resumed to ensure an adequate dosage.
