Description

Technical Field

[0001] This invention belongs to the field of nebulizer technology, specifically referring to a nebulizer for pediatric nursing care to prevent crying. Background Technology

[0002] Nebulized inhalation therapy is an important and effective treatment method for respiratory diseases. It treats various upper and lower respiratory system diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis, and other diseases occurring in the trachea, bronchi, alveoli, and pleural cavity. The nebulizer atomizes the medication into tiny particles, which are then inhaled and deposited in the respiratory tract and lungs, thus achieving painless, rapid, and effective treatment.

[0003] Children are prone to respiratory diseases. Nebulizer therapy can quickly deliver medication into the respiratory tract, thus improving the treatment effect. However, children may not cooperate with nebulizer therapy due to fear or hyperactivity. In addition, existing nebulizers will continue to produce nebulization after being turned on, and will not stop nebulizing when the nebulizer is removed from the mouth and nose, resulting in waste of medication.

[0004] Therefore, a pediatric nursing anti-crying medication nebulizer is needed to solve the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a pediatric nursing anti-crying nebulizer that can attract children's attention by blowing air to reduce crying. When the nebulizer is removed from the mouth and nose, the piezoelectric ceramic plate detaches from the liquid and stops producing droplets, thus avoiding waste of the liquid. At the same time, the adjustment plate can always keep the level to ensure smooth nebulization.

[0006] The technical solution adopted by this invention is as follows: This invention proposes a pediatric nursing anti-crying nebulizer, including a spherical shell made of transparent material. An adjustment disc is provided inside the spherical shell, and multiple universal ball bearings are provided on the outer wall of the adjustment disc. The universal ball bearings roll on the inner wall of the spherical shell. A through hole is provided at the center of the adjustment disc. A ventilation tube is provided at the through hole on the upper wall of the adjustment disc. Multiple ventilation holes are provided on the outer wall of the ventilation tube. An air bladder is surrounded by the outer wall of the ventilation tube. A balance cylinder is provided on the lower wall of the adjustment disc, and a liquid passage hole is provided on the bottom wall of the balance cylinder. A buoyancy disc is provided inside the balance cylinder, and a central hole is provided at the center of the buoyancy disc. Pressure detection components are provided at equal intervals around the axis on the buoyancy disc. A piezoelectric ceramic plate is fixed on the pressure detection component and is located inside the central hole of the buoyancy disc. An external connecting hose is connected to the outer wall of the spherical shell. A nebulizing breathing component is connected to the outer end of the external connecting hose. A blower is connected to the nebulizing breathing component. The upper end of the external connecting hose and the ventilation tube are connected through an internal connecting hose.

[0007] Furthermore, the pressure determination component includes a sliding tube, a balloon, a buffer spring, and a connecting arm. The sliding tube is slidably disposed on the upper wall of the buoyancy disk, the balloon is disposed at the lower end of the sliding tube, one end of the connecting arm is fixedly disposed on the upper end of the sliding tube, the upper end of the buffer spring is fixedly disposed on the other end of the connecting arm, and the lower end of the buffer spring is fixedly disposed on the piezoelectric ceramic plate.

[0008] Furthermore, the nebulized breathing assembly includes a breathing tube, a sealing slider, a retaining ring, a nebulizer nozzle, and a compression spring. One end of the breathing tube is connected to the end of an external connecting hose, and the nebulizer nozzle is located at the other end of the breathing tube and communicates with it. The sealing slider is slidably disposed inside the breathing tube, the retaining ring is fixedly disposed inside the breathing tube, and the compression spring is disposed inside the breathing tube. The two ends of the compression spring are respectively located on the inner end face of the breathing tube connected to the external connecting hose and the end of the sealing slider. An air inlet is provided through the center of the sealing slider, and a one-way gas valve is provided at the end of the air inlet near the nebulizer nozzle.

[0009] Furthermore, the air inlet of the blower is connected to the outer wall of the breathing tube, and in the initial state, the sealing slider is located at the connection between the blower and the breathing tube.

[0010] Furthermore, the lower end of the balance cylinder is provided with a second universal ball bearing, which rolls on the inner wall of the spherical shell.

[0011] Furthermore, the outer wall of the spherical shell is provided with a handle.

[0012] Furthermore, a liquid passage pipe is provided on the outer wall of the spherical shell near the handle, and a switch is provided on the liquid passage pipe.

[0013] Furthermore, the center of the adjustment disc coincides with the center of the spherical shell.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The sealing slider, compression spring and gas one-way valve in the nebulizer breathing component work together to allow children to inhale the droplets of the medicine when they inhale and for the blower to unfold when they exhale. This can attract children's attention and solve the problem of children being unable to cooperate with nebulizer treatment due to fear or hyperactivity. At the same time, it matches the child's breathing rhythm and improves the comfort of use. 2. When the nebulizer is removed from the mouth and nose, the air pressure in the airbag increases, causing the balloon to expand. The pressure detection component then causes the piezoelectric ceramic plate to detach from the liquid surface, stopping the generation of droplets. When you inhale again, the piezoelectric ceramic plate resets and resumes nebulization, thus avoiding the waste of liquid caused by continuous nebulization after the nebulizer is removed from the mouth and nose. 3. The adjustment disc rolls with the inner wall of the ball shell through universal ball bearings, and the center of the ball shell coincides with the center of the ball shell. Under the action of the gravity of the balance cylinder, even if the child tilts the ball shell handle, the adjustment disc can always remain horizontal. During atomization, it can ensure stable contact between the piezoelectric ceramic plate and the liquid medicine, and ensure that the atomization process is not affected by the tilt of the ball shell. 4. The sphere is equipped with a handle, making it easy for children to hold or for medical staff and parents to operate. The sphere is made of transparent material and is equipped with a liquid inlet tube with a switch, which makes it easy to observe the remaining liquid and to conveniently fill the sphere with liquid.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this invention proposes a pediatric nursing anti-crying nebulizer, comprising a spherical shell 1 made of transparent material. An adjusting disc 2 is located inside the spherical shell 1. Multiple universal ball bearings 3 are located on the outer wall of the adjusting disc 2, rolling on the inner wall of the spherical shell 1. A through hole 4 is provided at the center of the adjusting disc 2. An air vent 5 is located at the through hole 4 on the upper wall of the adjusting disc 2. Multiple air vents 6 are located on the outer wall of the air vent 5. An air bladder 7 is surrounded by the outer wall of the air vent 5. A balancing cylinder 8 is located on the lower wall of the adjusting disc 2, and a liquid passage hole 9 is located on the bottom wall of the balancing cylinder 8. The balance cylinder 8 has a buoyancy disk 10 inside, and a central hole 11 is provided in the center of the buoyancy disk 10. Pressure determination components 12 are provided at equal intervals around the axis on the buoyancy disk 10. A piezoelectric ceramic plate 13 is fixed on the pressure determination component 12. The piezoelectric ceramic plate 13 is located in the central hole 11 of the buoyancy disk 10. An external connecting hose 14 is connected to the outer wall of the spherical shell 1. An atomizing breathing component 15 is connected to the outer end of the external connecting hose 14. A blower 16 is connected to the atomizing breathing component 15. The upper end of the external connecting hose 14 is connected to the ventilation pipe 5 through an internal connecting hose 17.

[0021] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the pressure determination component 12 includes a sliding tube 18, a balloon 19, a buffer spring 20, and a connecting arm 21. The sliding tube 18 is slidably disposed through the upper wall of the buoyancy disk 10. The balloon 19 is disposed at the lower end of the sliding tube 18. One end of the connecting arm 21 is fixedly disposed at the upper end of the sliding tube 18. The upper end of the buffer spring 20 is fixedly disposed at the other end of the connecting arm 21. The lower end of the buffer spring 20 is fixedly disposed on the piezoelectric ceramic plate 13. When the piezoelectric ceramic plate 13 is energized, the piezoelectric ceramic plate 13 can vibrate, thereby atomizing the liquid medicine.

[0022] like Figure 1 , Figure 2 and Figure 6 As shown, the nebulized breathing assembly 15 includes a breathing tube 22, a sealing slider 23, a retaining ring 24, a nebulizer nozzle 25, and a compression spring 26. One end of the breathing tube 22 is connected to the end of the external connecting hose 14. The nebulizer nozzle 25 is located at the other end of the breathing tube 22 and communicates with it. The sealing slider 23 is slidably disposed inside the breathing tube 22. The retaining ring 24 is fixedly disposed inside the breathing tube 22. The compression spring 26 is disposed inside the breathing tube 22. The two ends of the compression spring 26 are respectively located on the inner end face of the breathing tube 22 connected to the external connecting hose 14 and the end of the sealing slider 23. An inhalation hole 30 is provided through the center of the sealing slider 23. A gas one-way valve 31 is provided at the end of the inhalation hole 30 near the nebulizer nozzle 25. When the patient inhales, gas can enter the breathing tube 22 from the ventilation tube 5, the inner connecting hose 17, and the outer connecting hose 14, and then be inhaled into the patient's mouth from the inhalation hole 30, the gas one-way valve 31, and the nebulizer nozzle 25.

[0023] like Figure 6 As shown, the air inlet of the blower 16 is connected to the outer wall of the breathing tube 22. In the initial state, the sealing slider 23 is located at the connection between the blower 16 and the breathing tube 22, at which time the sealing slider 23 blocks the air inlet of the blower 16.

[0024] like Figure 2 , Figure 3 and Figure 4 As shown, the lower end of the balance cylinder 8 is provided with universal ball bearing 32, which rolls on the inner wall of the spherical shell 1.

[0025] like Figure 1 and Figure 2 As shown, the outer wall of the spherical shell 1 is provided with a handle 27.

[0026] like Figure 1 As shown, a liquid passage pipe 28 is provided on the outer wall of the spherical shell 1 near the handle 27, and a switch 29 is provided on the liquid passage pipe 28 to facilitate filling the spherical shell 1 with liquid medicine.

[0027] like Figure 1 and Figure 2 As shown, the center of the adjustment disk 2 coincides with the center of the spherical shell 1. As the spherical shell 1 tilts, the adjustment disk 2 can always remain horizontal inside the spherical shell 1.

[0028] In actual use, hold the handle 27 with your hand so that the spherical shell 1 is vertically upward, turn on the switch 29, and fill the spherical shell 1 with liquid through the liquid pipe 28. The spherical shell 1 is made of transparent material. Observe the inside of the spherical shell 1. The filled liquid is lower than the lower wall of the adjustment plate 2. The liquid enters the balance cylinder 8 through the liquid hole 9. The buoyancy plate 10 always floats on the liquid surface. At this time, the piezoelectric ceramic plate 13 is in contact with the liquid surface. Handle 27 can be handed to a child patient. When the child patient tilts handle 27, the adjustment disc 2 remains horizontal under the gravity of the balance cylinder 8. The medication, due to gravity, is located at the lower part of the spherical shell 1, energizing the piezoelectric ceramic plate 13. The piezoelectric ceramic plate 13 vibrates, generating droplets. The droplets enter the inner connecting hose 17 through the ventilation tube 5, and simultaneously enter the air bag 7 through the ventilation hole 6 on the ventilation tube 5. The patient inhales with the nebulizer mouthpiece 25 in their mouth. The droplets in the ventilation tube 5 enter the breathing tube 22 through the inner connecting hose 17 and the outer connecting hose 14, and then... The gas is inhaled through the inhalation port 30, the one-way gas valve 31, and the nebulizer nozzle 25 into the patient's mouth. When the patient exhales, the gas pushes the sealing slider 23, which compresses the pressure spring 26. The sealing slider 23 is offset from the air inlet of the blower 16, and the gas enters the blower 16. The blower 16 unfolds to attract the attention of the child patient. When the patient inhales again, the pressure spring 26 pushes the sealing slider 23, which locks into the retaining ring 24 and blocks the air inlet of the blower 16. By repeating the inhalation and exhalation, the patient can inhale the mist droplets and blow the blower 16. When the child patient stops inhaling and exhaling, the generated droplets can only enter the air bag 7 through the air vent 6 on the air tube 5. Therefore, the air pressure in the air bag 7 increases, the air pressure in the balance cylinder 8 increases, and the gas enters the balloon 19 through the sliding tube 18. The balloon 19 inflates and is immersed in the medicine liquid, thus increasing the buoyancy of the balloon 19. The balloon 19 drives the sliding tube 18 to move upward, the sliding tube 18 drives the connecting arm 21 to move upward, the connecting arm 21 drives the buffer spring 20 to move upward, and the buffer spring 20 pulls the piezoelectric ceramic plate 13 upward. The piezoelectric ceramic plate 13 detaches from the surface of the medicine liquid, stops the generation of medicine liquid droplets, and avoids the waste of medicine liquid. When the patient inhales again, the droplets in the airbag 7 enter the ventilation tube 5 through the ventilation port 6, pass through the inner connecting hose 17 and the outer connecting hose 14 into the breathing tube 22, and then enter the patient's mouth through the inhalation port 30, the gas one-way valve 31 and the nebulizer nozzle 25. The air pressure in the airbag 7 decreases, and the gas in the balloon 19 enters the upper side of the buoyancy plate 10 of the balance cylinder 8 through the sliding tube 18. Under the weight of the connecting arm 21, the sliding tube 18 and the piezoelectric ceramic plate 13, the sliding tube 18 and the connecting arm 21 move downward. The connecting arm 21 drives the buffer spring 20 and the piezoelectric ceramic plate 13 to move downward. The piezoelectric ceramic plate 13 comes into contact with the liquid medicine again, thereby generating liquid medicine droplets again.
