Aerosol device for respiratory diseases

Abstract

This invention discloses a nebulizer for respiratory diseases, relating to the field of medical auxiliary device technology. It includes a nebulizer with a first square delivery tube connected to it. A second square delivery tube is connected to the end of the first square delivery tube away from the nebulizer. The second square delivery tube has a first insertion groove inside. When not in use, an elastic rubber seat drives a rigid connecting plate and a barrier plate to seal the second square delivery tube. During sealing, the barrier plate prevents external contamination from entering the second square delivery tube when not in use. Furthermore, during connection to a breathing mask, the connecting section of the breathing mask abuts against the rigid connecting plate and the barrier plate, causing the barrier plate to tilt. This tilt allows the second square delivery tube to connect with the drug inlet bend, and the barrier plate does not obstruct the drug delivery from the second square delivery tube.

Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically to a nebulizer for respiratory diseases. Background Technology

[0002] Nebulizers are an important and effective treatment method for respiratory diseases. They atomize medication into tiny particles, which are then inhaled and deposited in the respiratory tract and lungs, achieving painless, rapid, and effective treatment. Nebulizer inhalation therapy refers to a method of drug delivery that uses a specialized device to disperse inhaled medication into an aerosol form. During inhalation, the aerosol is carried into the respiratory system by the airflow. It allows the medication to act directly on the respiratory mucosa, achieving the goals of cleaning and humidifying the airway, and providing local and systemic treatment.

[0003] The patent titled "A Breathing Nebulizer Device with a One-Way Anti-Pollution Nebulizing Tube," publication number CN110464928B, addresses the issue that existing nebulizer devices, due to the generally low mist pressure within the nebulizer, allow thicker exhaled air, especially from sneezing or mouth, to flow back into the nebulizer, causing extensive contamination. Furthermore, after a patient finishes using the device and the nebulizer mask is removed, external contaminants can enter the nebulizer, further contaminating it and affecting its future use. This patent addresses this issue by incorporating a one-way anti-pollution structure at the end of the connecting structure, preventing contamination when the airway... When the I-connector is fixed at the end of the connecting structure, the one-way anti-pollution structure connects the breathing mask and the nebulizer. When the I-connector is detached from the end of the connecting structure, the one-way anti-pollution structure disconnects the breathing mask and the nebulizer. This effectively prevents external environmental pollution from affecting the inside of the nebulizer, prevents gas pollution during subsequent use, and prevents cross-infection. However, when forming the connecting channel, the connecting gap is between the inner and outer membranes. Although a connecting gap is formed, it affects the amount of medication sprayed by the nebulizer. A large amount of nebulized medication will be blocked by the inner and outer membranes. Therefore, a respiratory disease nebulization device is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a nebulization device for respiratory diseases to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a respiratory disease nebulization device, comprising a nebulizer, a first square delivery tube connected to the nebulizer, a second square delivery tube connected to the end of the first square delivery tube away from the nebulizer, a first insertion groove provided inside the second square delivery tube, an elastic rubber seat integrally formed on the inner top wall of the second square delivery tube, a rigid connecting plate integrally formed inside the elastic rubber seat, a barrier plate integrally formed outside the rigid connecting plate, a breathing mask inserted into the first insertion groove, a drug inlet bend connected to the inlet and outlet of the breathing mask, and the outlet of the drug inlet bend being inclined downward.

[0006] Preferably, an iron connecting block is integrally formed on the side of the barrier plate away from the rigid connecting plate, and a magnetic block is integrally formed on the inner bottom wall of the second square conveying pipe.

[0007] Preferably, the iron connecting block has a storage cavity inside, the storage cavity is filled with iron powder, the magnetic block has a second insertion groove inside, and an elastic extension membrane is integrally formed at the middle position of the bottom wall of the iron connecting block.

[0008] Preferably, the inner wall of the second insertion slot is integrally formed with multiple magnetic rubber backward-facing ratchet plates.

[0009] Preferably, an electrostatic dustproof sticker is affixed to the breathing mask near the outlet of the second square delivery tube.

[0010] Preferably, the electrostatic dustproof sticker has multiple easy-tear marks, and the barrier plate is integrally formed on the side near the electrostatic dustproof sticker.

[0011] Preferably, the inner wall of the breathing mask is integrally formed with an arc-shaped inverted plate, which is arc-shaped and located below the air outlet of the drug inlet bend.

[0012] Preferably, the interior of the second square conveying pipe is integrally formed with a third insertion groove, which is connected to the first insertion groove.

[0013] Preferably, the inner wall of the third insertion slot and the outer wall surface of the breathing mask that is inserted into the third insertion slot are both rough surfaces.

[0014] Preferably, auxiliary rollers are rotatably connected to both sides of the rigid connecting plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In this invention, when not in use, the elastic rubber seat drives the rigid connecting plate and the barrier plate to seal the second square delivery tube. During the sealing process, the barrier plate ensures that external contamination is prevented from entering the interior of the second square delivery tube when not in use. Furthermore, during the connection of the breathing mask, the connecting section of the breathing mask abuts against the rigid connecting plate and the barrier plate, thereby causing the barrier plate to tilt. When the barrier plate tilts, it can connect the second square delivery tube with the drug inlet bend, and the barrier plate will not obstruct the drug output of the second square delivery tube.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1, such as Figure 1 As shown, this application discloses a respiratory disease nebulization device, including a nebulizer 100. A first square delivery tube 101 is connected to the nebulizer 100. A second square delivery tube 102 is connected to the end of the first square delivery tube 101 away from the nebulizer 100. A first insertion groove 103 is provided inside the second square delivery tube 102. An elastic rubber seat 106 is integrally formed on the inner top wall of the second square delivery tube 102. A rigid connecting plate 107 is integrally formed inside the elastic rubber seat 106. A barrier plate 108 is integrally formed on the outside of the rigid connecting plate 107. A breathing mask 104 is inserted into the first insertion groove 103. A drug inlet bend 105 is connected to the air inlet and outlet of the breathing mask 104. The outlet of the drug inlet bend 105 is inclined downward.

[0026] Specifically, during use, the user can activate the nebulizer 100 to atomize the medicine and deliver it into the first square delivery tube 101. After the medicine enters the first square delivery tube 101, it will continue to be delivered into the second square delivery tube 102. After entering the second square delivery tube 102, the medicine will be delivered into the inlet bend tube 105. When the atomized medicine enters the inlet bend tube 105, it will be sprayed downward through the outlet of the inlet bend tube 105 and enter the breathing mask 104. After the medicine enters the breathing mask 104, the user can inhale it by fastening the breathing mask 104 to the mouth and nose.

[0027] Furthermore, when switching to the next patient for medication inhalation, to avoid cross-infection, the breathing mask 104 is usually replaced. During the replacement process, the user can pull the plug section of the original breathing mask 104 out of the first plug slot 103 and insert the new breathing mask 104 into the first plug slot 103, thus completing the replacement of the breathing mask 104. When the new breathing mask 104 is inserted into the first plug slot 103, the plug section of the breathing mask 104 will abut against the rigid connecting plate 107. During the process of the plug section of the breathing mask 104 abutting against the rigid connecting plate 107, the rigid connecting plate 107 will change direction due to the force. When the direction changes, the elastic rubber seat 106 will be further squeezed, causing the elastic rubber seat 106 to deform. When the insertion section of the breathing mask 104 is fully inserted into the first insertion slot 103, the barrier plate 108 will tilt under the action of the rigid connecting plate 107. When the barrier plate 108 is fully tilted, it will no longer block the end of the second square delivery tube 102, thereby connecting the second square delivery tube 102 with the drug inlet bend 105. The liquid medicine delivered to the second square delivery tube 102 will continue to enter the drug inlet bend 105, thereby completely delivering the medicine into the breathing mask 104.

[0028] like Figure 2 As shown, when the insertion section of the breathing mask 104 is fully inserted into the first insertion slot 103, the insertion section of the breathing mask 104 will abut against the rigid connecting plate 107 and cause the blocking plate 108 to fully tilt up. The overall process will not block the delivery of the medicine. When the insertion section of the breathing mask 104 is pulled out of the first insertion slot 103, the deformed elastic rubber seat 106 will rebound due to the loss of abutment force. After the rebound, it will cause the rigid connecting plate 107 to spring back to its original position, thereby re-sealing the outlet of the second square delivery tube 102.

[0029] like Figures 1-2 As shown, the inner wall of the breathing mask 104 is integrally formed with an arc-shaped inverted plate 600, which is arc-shaped and located below the air outlet of the drug inlet bend 105.

[0030] Specifically, when the atomized medicine continuously enters the breathing mask 104 through the inlet bend 105, it will first come into contact with the arc-shaped inverted plate 600. After the atomized medicine comes into contact with the arc-shaped inverted plate 600, it will move upward through the arc shape of the arc-shaped inverted plate 600, thereby aiming at the human mouth and nose position and delivering the medicine to the human mouth and nose position more concentratedly.

[0031] like Figure 1As shown, the interior of the second square conveying pipe 102 is integrally formed with a third insertion groove 700, which is connected to the first insertion groove 103.

[0032] Specifically, the third insertion slot 700 guides the insertion section of the breathing mask 104 and ensures the stability of the insertion section of the breathing mask 104 inside the second square delivery tube 102. The inner wall of the third insertion slot 700 and the outer wall surface of the breathing mask 104 inserted into the third insertion slot 700 are both rough. The rough surface prevents the insertion section of the breathing mask 104 from sliding out of the third insertion slot 700 and prevents the breathing mask 104 from detaching from the second square delivery tube 102.

[0033] like Figure 3 As shown, an electrostatic dustproof sticker 500 is attached to the breathing mask 104 near the outlet of the second square delivery tube 102.

[0034] Specifically, during use, when the barrier plate 108 tilts, the electrostatic dustproof sticker 500 will come into contact with one side of the barrier plate 108, and the electrostatic dustproof sticker 500 adhering to one side of the barrier plate 108 will further ensure the cleanliness of the inside of the second square conveying pipe 102.

[0035] like Figure 3 As shown, both sides of the rigid connecting plate 107 are rotatably connected to auxiliary rollers 800. During use, when the plug section of the breathing mask 104 is inserted into the first plug slot 103 and the rigid connecting plate 107 is pushed, the auxiliary rollers 800 can assist the rigid connecting plate 107 to tilt. When the breathing mask 104 is pulled out of the first plug slot 103, the auxiliary rollers 800 can assist the breathing mask 104 to separate from the first plug slot 103.

[0036] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with the prior art, in this embodiment, when not in use, the elastic rubber seat 106 drives the rigid connecting plate 107 and the barrier plate 108 to block the second square delivery tube 102. During the blocking process, it is ensured that external contamination is prevented from entering the interior of the second square delivery tube 102 when not in use. Furthermore, during the connection of the breathing mask 104, the connecting section of the breathing mask 104 abuts against the rigid connecting plate 107 and the barrier plate 108, thereby causing the barrier plate 108 to tilt. When the barrier plate 108 tilts, the second square delivery tube 102 can be connected to the drug inlet bend 105, and the barrier plate 108 will not obstruct the drug output of the second square delivery tube 102.

[0037] Example 2: Considering that during use, although the barrier plate 108 can block the second square conveying pipe 102 when not in use, the barrier plate 108 is connected to the rigid connecting plate 107 via the elastic rubber seat 106. However, when shaking occurs, because the bottom of the barrier plate 108 is not effectively connected to the second square conveying pipe 102, the bottom of the barrier plate 108 frequently lifts up during shaking, resulting in frequent opening and closing between the second square conveying pipe 102 and the barrier plate 108. To address the above technical problems, this application proposes the following technical solution to solve the above technical problems, specifically:

[0038] like Figures 5-6 As shown, an iron connecting block 200 is integrally formed on the side of the barrier plate 108 away from the rigid connecting plate 107, and a magnetic block 201 is integrally formed on the inner bottom wall of the second square conveying pipe 102.

[0039] Specifically, during use, the iron connecting block 200 will be attracted by the magnetic block 201 in the closed state. Thus, when the rigid connecting plate 107 is not under continuous force, the magnetic block 201 will continue to attract the iron connecting block 200, ensuring that the barrier plate 108 continuously blocks the port of the second square conveying pipe 102, reducing the phenomenon of the barrier plate 108 frequently opening when not in use.

[0040] like Figure 3 As shown, the electrostatic dustproof sticker 500 has multiple easy-tear marks 501. The barrier plate 108 has an integrally formed 502 on the side near the electrostatic dustproof sticker 500. When the barrier plate 108 is raised to abut and separate the electrostatic dustproof sticker 500 from the outlet end of the breathing mask 104, the multiple 502s on the outside of the barrier plate 108 cut the electrostatic dustproof sticker 500. With the help of the easy-tear marks 501, the electrostatic dustproof sticker 500 can be quickly separated from the outlet end of the breathing mask 104.

[0041] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 1, in this embodiment, when the barrier plate 108 is in a normal state, the iron connecting block 200 will continuously be attracted by the magnetic block 201. When the barrier plate 108 is attracted by the magnetic block 201, it can be quickly pulled back to its original position when the rigid connecting plate 107 is forced to tilt the barrier plate 108, thereby reducing the continuous opening of the barrier plate 108 and avoiding the frequent opening of the barrier plate 108 under slight force, thus reducing the situation where external pollution enters the interior of the second square conveying pipe 102 under frequent opening.

[0042] Example 3: Considering that during use, although the magnetic block 201 can attract the iron connecting block 200, reducing the frequent opening of the barrier plate 108, the connection between the magnetic block 201 and the iron connecting block 200 may become unstable under continuous shaking and slight pressure on the rigid connecting plate 107. Furthermore, the barrier plate 108 may still tilt slightly under slight force on the rigid connecting plate 107, resulting in an opening in the second square conveying pipe 102. To address these technical problems, this application proposes the following technical solution:

[0043] like Figure 5 As shown, the iron connecting block 200 has a storage cavity 300 inside, which is filled with iron powder 401. The magnetic block 201 has a second insertion groove 202 inside, and an elastic extension membrane 402 is integrally formed at the middle position of the bottom wall of the iron connecting block 200.

[0044] Specifically, when the iron connecting block 200 is attracted by the magnetic block 201, the iron powder 401 located inside the storage cavity 300 will also be attracted by the magnetic block 201. Furthermore, due to the elastic extension membrane 402, when the iron powder 401 is attracted by the magnetic block 201, the flowing iron powder 401 will squeeze the elastic extension membrane 402, causing the elastic extension membrane 402 to gradually move closer to the position of the magnetic block 201. Also, due to the second insertion groove 202, the attracted iron powder 401 will gradually squeeze the elastic extension membrane 402, causing the elastic extension membrane 402 to deform downwards and insert into the interior of the second insertion groove 202, further forming an insertion segment. When the deformed iron powder 401 and the elastic extension membrane 402 are inserted into the interior of the second insertion groove 202, a connection can be further formed, further reducing the phenomenon of frequent openings.

[0045] like Figure 5 As shown, the inner wall of the second insertion groove 202 is integrally formed with multiple magnetic rubber backward ratchet plates 400. With the setting of the magnetic rubber backward ratchet plates 400, when the iron powder 401 drives the elastic extension membrane 402 to fully enter the interior of the second insertion groove 202, the multiple magnetic rubber backward ratchet plates 400 on the inner wall of the second insertion groove 202 will further insert into the interior of the elastic extension membrane 402, so that the elastic extension membrane 402 and the magnetic rubber backward ratchet plates 400 are further connected. Thus, even under slight force, the rigid connecting plate 107 will not be pulled by the connection between the elastic extension membrane 402 and the magnetic rubber backward ratchet plates 400, and even under slight force, there will be no excessive warping.

[0046] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 2, in this embodiment, when the magnetic block 201 adsorbs the iron connecting block 200, the iron powder 401 will cause the elastic extension membrane 402 to deform, and the deformed elastic extension membrane 402 will be inserted into the interior of the second insertion slot 202, further enhancing the stability between the barrier plate 108 and the second square conveying pipe 102 when not in use. Even if the rigid connecting plate 107 is slightly stressed, the barrier plate 108 will be pulled by the elastic extension membrane 402 below, and will not continuously tilt up, reducing the opening phenomenon of the second square conveying pipe 102 when not in use, and further reducing the situation of dirt entering the interior of the second square conveying pipe 102.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
