Abstract
Description
Technical Field
[0001] This invention relates to the field of vaccine atomization technology, and more specifically to a vaccine atomization device. Background Technology
[0002] Vaccine nebulization involves using a medical nebulizer to convert liquid vaccines into aerosol particles with a diameter of 1-5 micrometers. The recipient takes a deep breath through a special nebulizer cup to ensure that the vaccine particles are fully deposited in the respiratory tract and lung tissue. After inhalation, the recipient needs to hold their breath for more than five seconds to ensure effective adhesion of the vaccine.
[0003] In existing technologies, a dedicated nebulizer is typically used to nebulize a fixed amount of vaccine, which is then introduced into a dedicated nebulizer cup. The recipient inhales the vaccine from the nebulizer cup into their respiratory tract through their mouth and holds their breath to complete the vaccination. This method has advantages such as non-invasive vaccination, dose saving, and convenient transportation. Generally, the dose required for nebulization is less than that required for injection, and with the same production capacity, it can cover a larger population. Similarly, non-invasive vaccination provides great convenience for children. In influenza vaccination, nebulization is more acceptable to people, especially children, than injection.
[0004] During nebulized vaccination, special attention must be paid to the vaccination steps. Before inhaling the nebulized vaccine, you should try to expel as much air as possible from your lungs, and then quickly inhale the vaccine. After inhalation, you must hold your breath for more than five seconds. These steps are more easily completed in adult vaccination, and occasionally people forget to hold their breath or do not inhale completely. However, for children, the nebulized vaccination steps must be supervised by a nurse or guardian, otherwise, it is easy for them to inhale too quickly or forget to hold their breath, resulting in poor vaccination effect. Summary of the Invention
[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a vaccine atomization inoculation device, which can effectively solve the problem of how to reduce the difficulty of inoculation in the existing technology.
[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a vaccine nebulization device, comprising a nebulizing cup and a cap fixedly installed on the top of the nebulizing cup by threads. An injection tube and an inhalation tube are fixedly connected through the cap. An inhalation mouthpiece is connected to the top of the inhalation tube and is installed at the top of the inhalation tube by insertion and removal. The device also includes: The atomizing cup body includes a lower cup body at the bottom and an upper cup body that is slidably inserted into the lower cup body. The lid is installed on the top of the upper cup body. Multiple magnets are embedded and fixedly connected to the top of the lower cup body. Multiple magnets corresponding to the magnets are fixedly connected to the bottom of the upper cup body. A spring support is sleeved on the bottom of the upper cup body. The spring support is located inside the lower cup body and between the lower cup body and the upper cup body, providing elastic support for the lower cup body and the upper cup body.
[0007] Furthermore, the inner bottom plate of the lower cup body is symmetrically and fixedly connected to two support rods. The top of the support rods is fixedly connected to a fixed contact ring. The bottom of the suction tube is rotatably connected to a sealing plate through a torsion spring. Under the support of the torsion spring, the sealing plate blocks the bottom of the suction tube. After the sealing plate moves down to contact the fixed contact ring, it flips over and opens the bottom of the suction tube.
[0008] Furthermore, multiple flexible friction strips are embedded and fixedly connected to the outer diameter wall where the upper cup body and the lower cup body contact each other. Multiple receiving grooves are opened at the top inner diameter of the lower cup body. The positions of the receiving grooves, magnets, and flexible friction strips correspond one-to-one. The flexible friction strips are attached to the receiving grooves. Rubber friction blocks are fixedly connected to several of the receiving grooves to increase the contact with the flexible friction strips.
[0009] Furthermore, the flexible friction strip includes an equal number of rubber strips one, two, and three. The roughness of the parts of rubber strips one, two, and three that contact the receiving groove gradually increases, and rubber strips one, two, and three are arranged uniformly in sequence. The number of rubber friction blocks is the same as the number of rubber strips one, and the rubber friction blocks are evenly spaced.
[0010] Furthermore, the spring support includes rings at the top and bottom, with a sealing ring fixedly connected to the inner diameter of the rings. The sealing ring contacts the outer wall of the upper cup body and creates a seal. A return spring is fixedly connected between the two rings.
[0011] Furthermore, the support rod includes two sleeve rods symmetrically and fixedly connected to the bottom of the lower cup body. The top surface of the sleeve rods is flush with the top surface of the lower cup body. A sliding column is slidably inserted into the sleeve rod, and a spring is fixedly connected between the sliding column and the sleeve rod. The fixed contact ring is fixedly connected to the top of the sliding column. An iron block is fixedly connected to the bottom end of the sliding column. A magnet that generates magnetic attraction to the iron block is embedded and fixedly connected in the middle of the sliding column. An arc-shaped limiting plate is fixedly connected to the side of the sliding column corresponding to the position of the sealing plate. The arc-shaped limiting plate is used to catch the sealing plate after it is flipped.
[0012] Furthermore, the support rod includes two fixed plates symmetrically fixedly connected to the lower cup body, and the fixed contact ring is fixedly connected to the top of the two fixed plates. After the sealing plate is flipped over, it fits against the side wall of one of the fixed plates.
[0013] Furthermore, the inhalation mouthpiece includes a diffuser tube that is pluggably installed at the top of the inhalation tube. A hollow inhalation nozzle protrudes from the middle of the diffuser tube and communicates with the inhalation tube for the recipient to hold in their mouth. An annular sealing strip is fixedly connected to the top of the diffuser tube and fits around the recipient's mouth.
[0014] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. The atomizing cup is composed of separate upper and lower cups. During inhalation, the upper and lower cups can be compressed to assist in vaccine inhalation. In conjunction with the sealing plate opened by the fixed contact ring, the recipient cannot inhale the vaccine when not compressed, reminding the recipient to perform the compression process. Flexible friction strips provide frictional damping for the compression process of the upper and lower cups. By rotating the upper cup, different flexible friction strips can be selected, and different friction coefficients can be used to adjust the frictional damping, avoiding discomfort caused by rapid compression when the recipient inhales gas.
[0015] 2. The negative pressure generated during the separation of the upper and lower cups, combined with the retractable support rod, creates a certain negative pressure between them. This allows the vaccine to be injected into the atomizing cup via the injection tube, thus accelerating the vaccine delivery speed and aiding in the diffusion of atomized vaccine particles.
[0016] 3. By using a fixed plate, when the sealing plate rises, the inhalation tube connects with the inside of the nebulizer cup, allowing the negative pressure generated inside the nebulizer cup to be transmitted to the inhalation mouth. This causes the inhalation mouth to adhere to the recipient's mouth, allowing the recipient to clearly feel the breath-holding time and clearly know that the breath-holding time has ended when the negative pressure disappears. This helps remind the recipient to remember to hold their breath and also assists in reminding them of the breath-holding time. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0021] The present invention will be further described below with reference to embodiments.
[0022] A vaccine atomization device Example 1: Refer to Figures 1 to 13 The device includes an atomizing cup body 1 and a cap 2 that is threadedly fixed to the top of the atomizing cup body 1. An injection tube 3 and an inhalation tube 4 are threadedly and fixedly connected to the cap 2. An inhalation nozzle 5 is connected to the top of the inhalation tube 4 and is installed at the top of the inhalation tube 4 via a plug-in / plug-out method. The device also includes: The atomizing cup body 1 includes a lower cup body 101 at the bottom and an upper cup body 102 slidably inserted into the lower cup body 101. A lid 2 is installed on the top of the upper cup body 102. Multiple magnets 105 are embedded and fixedly connected to the top of the lower cup body 101. Multiple magnets 106 corresponding to the magnets 105 are fixedly connected to the bottom of the upper cup body 102. A spring support member 9 is sleeved on the bottom of the upper cup body 102. The spring support member 9 is located inside the lower cup body 101 and between the lower cup body 101 and the upper cup body 102, providing elastic support for the lower cup body 101 and the upper cup body 102. The spring support member 9 includes rings 901 at the top and bottom. A sealing ring 903 is fixedly connected to the inner diameter of the rings 901. The sealing ring 903 contacts the outer wall of the upper cup body 102 and creates a seal. A return spring 902 is fixedly connected between the two rings 901.
[0023] Influenza vaccination is the most widely used method of nebulized vaccination. Because it is an inhalation method, the vaccine is directly attached to the lower respiratory tract. Compared with injectable vaccines, it can save more doses and provide enough nebulized vaccines for the same production capacity. Before vaccination, the nebulized vaccine needs to be injected into the nebulizer cup 1 through the injection tube 3. After the recipient places their mouth into the inhalation mouthpiece 5, they will absorb the small particles of nebulized vaccine in the nebulizer cup 1. Then, they will hold their breath for more than five seconds to ensure that the vaccine adheres to the skin before completing the vaccination.
[0024] Before inhaling the vaccine, the recipient needs to expel as much air as possible from their lungs, then inhale sharply the air from the nebulizer cup 1. Simultaneously, one hand should hold the cap 2, and the other hand should support the bottom of the lower cup 101. Then, the lower cup 101 should be quickly pushed upwards, rapidly compressing the nebulized vaccine within both the lower and upper cups 102. This, combined with the recipient's inhalation, quickly draws in the nebulized particles, reducing residual particles in the lower and upper cups 101 and 102. After inhalation, the spring support 9 provides elastic support to the lower and upper cups 101 and 102, allowing them to return to their original positions, extended. The position of the lower cup 101 can then be adjusted. When the ring 901 slides between the lower cup 101 and the upper cup 102, it will not affect the rotation of the lower cup 101. Correspondingly, the sealing ring 903 at the inner diameter of the ring 901 can fit against the outside of the upper cup 102 during the compression of the lower cup 101 and the upper cup 102. Since the uppermost ring 901 will always press against the top inner side of the lower cup 101 during the compression of the lower cup 101 and the upper cup 102, the sealing ring 903 can increase the sealing effect to ensure that the atomized vaccine cannot escape from the gap between the lower cup 101 and the upper cup 102. Combined with the tight contact between the receiving groove 103 and the flexible friction strip 107, the sealing effect is guaranteed.
[0025] The compression action of the lower cup 101 and upper cup 102, combined with the inhalation of the vaccine by the recipient, can help the rapid inhalation of the nebulized vaccine. Even when the child forgets to exhale before inhaling, the compression action can still help the inhalation of the nebulized vaccine, ensuring that the recipient inhales a sufficient amount of vaccine, thereby ensuring the effectiveness of the vaccination.
[0026] Specifically, the inner bottom plate of the lower cup body 101 is symmetrically fixedly connected to two support rods 6. The top of the support rods 6 is fixedly connected to a fixed contact ring 7. The bottom of the suction tube 4 is rotatably connected to a sealing plate 8 through a torsion spring. Under the support of the torsion spring, the sealing plate 8 blocks the bottom of the suction tube 4. After the sealing plate 8 moves down to contact the fixed contact ring 7, it flips over and opens the bottom of the suction tube 4.
[0027] When the lower cup 101 and upper cup 102 are not compressed, the sealing plate 8, supported by the torsion spring, blocks the bottom of the inhalation tube 4. When the lower cup 101 and upper cup 102 are compressed, the sealing plate 8 moves down along with the cover 2 and the inhalation tube 4 and contacts the fixed contact ring 7 at the top of the support rod 6. After the flat end of the sealing plate 8 contacts the top of the fixed contact ring 7, it begins to flip under pressure and opens the bottom of the inhalation tube 4. In this way, the inhalation tube 4 can communicate with the space formed by the lower cup 101 and upper cup 102, and the atomized particles in the lower cup 101 and upper cup 102 can be inhaled by the recipient through the inhalation tube 4. Thus, if the recipient forgets to compress the lower cup 101 and upper cup 102, the atomized vaccine cannot be inhaled because the sealing plate 8 blocks the bottom of the inhalation tube 4. This reminds the recipient to compress the lower cup 101 and upper cup 102 when inhaling the vaccine, thus avoiding misoperation.
[0028] Specifically, multiple flexible friction strips 107 are embedded and fixedly connected to the outer diameter wall where the upper cup body 102 contacts the lower cup body 101. Multiple receiving grooves 103 are formed at the inner diameter of the top of the lower cup body 101. The positions of the receiving grooves 103, the magnets 106, and the flexible friction strips 107 correspond one-to-one. The flexible friction strips 107 are fitted into the receiving grooves 103. Rubber friction blocks 104 are fixedly connected to several receiving grooves 103 to increase contact with the flexible friction strips 107. 107 includes an equal number of rubber strips 1071, 1072, and 1073. The roughness of the parts of the rubber strips 1071, 1072, and 1073 that contact the receiving groove 103 gradually increases. The rubber strips 1071, 1072, and 1073 are arranged in a uniform sequence. The number of rubber friction blocks 104 is the same as the number of rubber strips 1071, and the rubber friction blocks 104 are evenly spaced.
[0029] When the lower cup 101 and upper cup 102 are compressed, the inner top of the lower cup 101 contacts the flexible friction strip 107. The friction between the rubber friction block 104 and the flexible friction strip 107 increases frictional damping for the opposing movement of the lower cup 101 and upper cup 102. This prevents a strong adult from compressing the lower cup 101 and upper cup 102 too quickly, which would cause the atomized vaccine particles to enter too rapidly. It also prevents the internal pressure of the lower cup 101 and upper cup 102 from increasing too rapidly. The recipient may experience discomfort during inhalation. The receiving groove 103 is designed to accommodate the slightly raised flexible friction strip 107. The flexible friction strip 107 is compressed within the receiving groove 103, ensuring that it fits firmly against the groove and creates a seal, preventing the atomized particles from escaping during compression. Without the receiving groove 103, the protrusion of the flexible friction strip 107 would cause excessive damping, and gaps would form between the flexible friction strip 107 and the lower cup 101 on both sides, which would hinder sealing.
[0030] When the lower cup 101 moves to its limit, the magnet 105 on the top of the lower cup 101 will attract the magnet 106 on the upper cup 102, fixing the positions of the lower cup 101 and the upper cup 102. Before the nebulized vaccine is introduced into the nebulizer cup 1 through the injection tube 3, the lower cup 101 or the upper cup 102 can be rotated to adjust the rubber friction block 104 to align with the rubber strip 1071, rubber strip 1072, or rubber strip 1073. Because the surface roughness, i.e., the coefficient of friction, of the three is different, the contact between the rubber friction block 104 and the rubber strip 1071, and the contact with the rubber strip 1072, will bring... The friction damping effect varies. When administering the vaccine to children or those with less strength, the rubber friction block 104 can be rotated to align with the rubber strip 1071. This allows the rubber friction block 104 to contact the rubber strip 1071 during the compression of the lower cup 101 and upper cup 102. This reduces the difficulty for those with less strength when compressing the lower cup 101 and upper cup 102 and does not limit the compression speed. For those who are visually stronger, the lower cup 101 can be rotated to align the position of the rubber friction block 104 with the rubber strip 1073. This prevents those with greater strength from using excessive force, which could cause the compression process to be too fast.
[0031] In the attached diagram, the number of surface protrusions indicates that the roughness of rubber strip 1071, rubber strip 2 1072, and rubber strip 3 1073 are different. In practical applications, different materials can be used to distinguish different roughnesses.
[0032] During the reset process, if the position of the rubber friction block 104 is outside the second rubber strip 1072, rotate one step to move the rubber friction block 104 onto the first rubber strip 1071. If the position of the rubber friction block 104 is outside the third rubber strip 1073, it is also only necessary to rotate one step to move the rubber friction block 104 onto the first rubber strip 1071. In this way, the friction damping is minimized, and the lower cup 101 and the upper cup 102 can be quickly reset under the support of the spring support member 9.
[0033] The rubber strips 1071, 1072, and 1073 in the flexible friction strip 107 can also be replaced by inflatable rubber bladders. The inflatable rubber bladders have air pressure and better deformation conditions, which can better fit with the receiving groove 103 or the rubber friction block 104.
[0034] Specifically, the support rod 6 includes two sleeve rods 602 symmetrically fixedly connected to the bottom of the lower cup body 101. The top surface of the sleeve rod 602 is flush with the top surface of the lower cup body 101. A sliding column 601 is slidably inserted into the sleeve rod 602, and a spring is fixedly connected between the sliding column 601 and the sleeve rod 602. A fixed contact ring 7 is fixedly connected to the top of the sliding column 601. An iron block 604 is fixedly connected to the bottom end of the sliding column 601. A magnet 605 that generates magnetic attraction to the iron block 604 is embedded and fixedly connected in the middle of the sliding column 601. An arc-shaped limiting plate 603 is fixedly connected to the side of the sliding column 601 corresponding to the position of the sealing plate 8. The arc-shaped limiting plate 603 is used to catch the sealing plate 8 after it is flipped.
[0035] In this embodiment, the support rod 6 forms a telescopic structure with a sliding column 601 and a sleeve rod 602, and the top surface of the sleeve rod 602 is flush with the top surface of the lower cup body 101. That is, the compression limit of the sliding column 601 and the sleeve rod 602 is the same as the compression limit of the lower cup body 101 and the upper cup body 102. When the lower cup body 101 and the upper cup body 102 are compressed, the sealing plate 8 moves down and contacts the fixed contact ring 7 at the top of the sliding column 601. When subjected to pressure, the sealing plate 8... The rotation begins, opening the bottom of the suction tube 4. The rotating sealing plate 8 then contacts the arc-shaped limiting plate 603 on the side of the sliding column 601, and its rotation is restricted by the protrusion on the side of the arc-shaped limiting plate 603. During the continuous compression of the lower cup 101 and the upper cup 102, the sealing plate 8 presses against the arc-shaped limiting plate 603, causing the sliding column 601 to continuously move downwards within the sleeve rod 602 until the lower cup 101 and the upper cup 102... Completely compressed, magnets 105 and 106 are attracted together. At this time, iron block 604 is also attracted by magnet 3. After the recipient completes inhalation, the atomizing cup 1 can be released, and the recipient can hold their breath voluntarily. This process is the same as the operation procedure of a conventional atomizing cup. Then, the lower cup 101 and upper cup 102 can be pulled apart, allowing magnets 105 and 106 to separate. The lower cup 101 and upper cup 102 reset under the support of spring support 9. At this time, the lower cup 101 and upper cup 102 quickly reset under the elastic force of spring support 9, and the sealing plate 8 quickly leaves the arc-shaped limiting plate 603. Under the support of torsion spring, the sealing plate 8 quickly flips back to below the suction tube 4 and blocks the bottom of the suction tube 4, disconnecting the space between the lower cup 101 and upper cup 102 from the outside. At this time, when the lower cup 101 and upper cup 102 reset, the lower cup 101 A certain negative pressure is formed inside the 02. This negative pressure is not large, but it helps the nebulized vaccine to be inhaled into the nebulizer cup 1 as quickly as possible when filling it. Since the amount of vaccine inhaled at one time is small, the negative pressure does not need to be too large. It is only to provide some assistance and acceleration during the replenishment process of the nebulized vaccine and to accelerate the diffusion of the nebulized particles. It should be noted that when the spring between the sliding column 601 and the sleeve rod 602 is fully extended, the supporting force must be greater than the torsion force of the torsion spring between the sealing plate 8 and the inhalation tube 4, otherwise the seal will not be strong enough. When the sealing plate 8 moves downward, it will directly press against the sliding post 601. Only when the spring between the sliding post 601 and the sleeve rod 602 is compressed to a force greater than the torsion force of the torsion spring on the sealing plate 8 can the sealing plate 8 flip. Furthermore, the return speed of the spring between the sliding post 601 and the sleeve rod 602 must be less than the return speed of the spring support 9. Careful selection of the reset spring 902 and related spring models is necessary. The attraction of the magnet 605 to the iron block 604 relies on the pressure of the lower cup 101 approaching the upper cup 102. Under spring support, the magnet 605 will slowly separate from the iron block 604.The upward speed of the sliding column 601 is limited, allowing the sealing plate 8 to quickly separate from the arc-shaped limiting plate 603.
[0036] Specifically, the inhalation mouthpiece 5 includes a diffuser tube 501 that is pluggable and installed at the top of the inhalation tube 4. A hollow inhalation mouthpiece 502 protrudes from the middle of the diffuser tube 501. The inhalation mouthpiece 502 is connected to the inhalation tube 4 and is placed in the mouth of the recipient. An annular sealing strip 503 is fixedly connected to the top of the diffuser tube 501 and fits around the mouth of the recipient.
[0037] When inhaling the vaccine, the recipient holds the inhalation nozzle 502 in their mouth. The nebulized vaccine is inhaled into the recipient's lungs through the inhalation tube 4 and the inhalation nozzle 502. When negative pressure is generated in the lower cup 101 and the upper cup 102, the annular sealing strip 503 on the edge of the diffuser tube 501 helps to fit the recipient's mouth and form a seal. At this time, the recipient does not need to continue holding the inhalation nozzle 502 in their mouth. The negative pressure can be absorbed by the recipient's mouth by utilizing the diffusion shape of the diffuser tube 501.
[0038] Example 2: Refer to Figures 1 to 8 , Figure 14 The support rod 6 includes two fixed plates 606 symmetrically fixedly connected inside the lower cup body 101, a fixed contact ring 7 fixedly connected to the top of the two fixed plates 606, and a sealing plate 8 flipped over to fit against the side wall of one of the fixed plates 606.
[0039] Unlike the previous embodiment, the support rod 6 consists of only two fixed plates 606. In this embodiment, the downward movement of the sealing plate 8 is caused by the pressure of the fixed contact ring 7, causing it to flip. After flipping, the sealing plate 8 is tightly attached to the side wall of one of the fixed plates 606. After the inhalation process is completed, the recipient's mouth should not leave the inhalation nozzle 5. Then, the lower cup 101 and the upper cup 102 are pulled apart, allowing the first magnet 105 and the second magnet 106 to separate. The lower cup 101 and the upper cup 102 are reset under the support of the spring support 9, while the sealing plate 8 remains vertical and slides on the fixed plate 606. At this time, the negative pressure generated by the extension of the lower cup 101 and the upper cup 102 will be transmitted to the recipient's mouth through the inhalation tube 4 and the inhalation nozzle 5. The recipient needs to hold their breath at this time, and the negative pressure will act on the recipient's mouth through the suction nozzle 5. At this time, the suction nozzle 5 will slightly adhere to the recipient's mouth. With the friction damping provided by the flexible friction strip 107, the extension speed of the lower cup 101 and the upper cup 102 is not fast, and has a certain delay effect. When the sealing plate 8 is still between the two fixing plates 606 at the top of the fixing plate 606, the negative pressure that the lower cup 101 and the upper cup 102 can act on the recipient's mouth is the maximum. When the sealing plate 8 leaves the fixing plate 606, the sealing plate 8 returns to the bottom of the suction tube 4 under the support of the torsion spring, blocking the bottom of the suction tube 4. At this time, the connection between the lower cup 101 and the upper cup 102 and the recipient's mouth is broken. If the pressure cannot be applied to the recipient's mouth through the inhalation mouthpiece 5, the recipient can lower the nebulizer cup 1 to complete the nebulized vaccine administration. This can be achieved by selecting a suitable return spring 902, rotating the lower cup 101, and aligning the rubber friction block 104 with the rubber strip three 1073 or rubber strip two 1072 to achieve appropriate frictional damping. This allows the generation of negative pressure and the duration of its application to be adjusted appropriately, for example, to allow the lower cup 101 and upper cup 102 to return to their original positions for six seconds or more, but more than five seconds and less than ten seconds. When the recipient holds their breath, the inhalation mouthpiece 5 adheres to their mouth. The recipient can maintain breath-holding while the negative pressure acts on their mouth, and the negative pressure will dissipate after the lower cup 101 and upper cup 102 are fully extended. The moment of disappearance, the awareness that there is no need to continue holding one's breath serves as a reminder to the recipient of the breath-holding time. Furthermore, the negative pressure adhering to the recipient's mouth helps children focus their attention on the adsorption process, preventing them from forgetting to hold their breath after inhalation. Conversely, due to children's playful nature, having something adhering to their mouths may also make them more likely to remember that they should hold their breath. The adsorption of the inhalation mouthpiece 5 on the mouth also helps to divert children's attention, allowing them to focus on the vaccination process. Similar to the previous embodiment, after the lower cup 101 and upper cup 102 are expanded, there is negative pressure inside. This negative pressure can accelerate the diffusion process of atomized particles within the atomizing cup 1 and also slightly accelerate the inhalation speed.
