Description

Technical Field

[0001] This invention relates to the field of age-friendly medical device technology, specifically an age-friendly nebulized respiratory drug delivery device. Background Technology

[0002] Currently, in the clinical treatment of respiratory diseases in the elderly, nebulized respiratory drug delivery, as a nebulizer-based drug delivery method specifically designed for therapeutic purposes, has become the mainstream treatment for chronic bronchitis, COPD, asthma, and aspiration pneumonia in the elderly due to its advantages such as local onset of action, minimal systemic side effects, and no need for hand-mouth coordination. It is an important application scenario for age-friendly medical devices in the biomedical engineering industry. A single nebulization treatment session for elderly patients usually lasts 10-15 minutes, and due to decreased physical strength and fatigue from prolonged sitting, they often need to complete the treatment in a semi-recumbent, supine, or lateral position, which places high demands on the positional adaptability and wearing comfort of the nebulizer.

[0003] For critically ill elderly patients requiring long-term, high-volume (5ml) drug administration, the mainstream clinical approach is to use a compression / jet nebulizer with a separate drug cup and main unit. These devices offer high nebulization efficiency and large drug cup capacity, but the drug cup is also relatively large and heavy, placing significantly higher demands on the load-bearing structure compared to portable nebulizers. A search revealed Chinese patent CN120754376A, which discloses an age-appropriate nebulized respiratory drug delivery device, relating to the field of nebulized respiratory devices. The device includes a breathing mask with a nebulization mechanism for easy nebulization and an adjustment mechanism for adjusting the nebulization mechanism. The nebulizing mechanism includes a medication cup, a conical tube, a sphere, and an air inlet tube. The adjustment mechanism includes a side rod and a push rod. The side rod is fixedly installed on the side end of the breathing mask, the push rod is located at the lower end of the side rod, and a top rod is fixedly installed at the upper end of the push rod. By setting an adjustable medication cup with multi-angle adjustment, the device can actively adapt to any position of elderly patients, such as supine or lateral, during nebulization. By dynamically adjusting the direction of the medication cup, it always keeps it perpendicular to the ground, ensuring that the medication always submerges the nebulizing element, thus solving the problem of nebulization failure caused by changes in the treatment posture of elderly patients in traditional nebulizers.

[0004] While the aforementioned technical solutions can adjust the vertical angle of the medication cup, they still suffer from problems such as the mask being pulled and leaking air due to the heavy load of the medication cup hanging on its side, and the difficulty for the elderly to maintain continuous hand support. They cannot achieve a completely hands-free experience. More importantly, the existing technology suffers from the technical bias that fixed support is sufficient, ignoring the decisive influence of the spatial geometric relationship between the medication cup and the mask on the flow pattern of the medication mist in lying scenarios. It can only adjust the verticality of the cup and cannot independently adapt to the delivery height and horizontal distance under different lying positions. It is very easy for the corrugated tube to bend or create height differences under different lying positions such as semi-reclining, supine, and lateral lying, which will disrupt the laminar flow delivery of the medication mist, cause turbulent deposition, significantly reduce the effective deposition rate in the lungs, and have poor adaptability to different individuals. Therefore, an age-appropriate nebulized respiratory drug delivery device is proposed to solve the above problems. Summary of the Invention

[0005] To address the above problems, the present invention provides the following technical solution: An age-friendly nebulized respiratory drug delivery device includes a compressor nebulizer, a drug cup connected to the compressor nebulizer, the bottom of the drug cup being connected to the nebulization outlet of the compressor nebulizer via a flexible tube, a corrugated flexible tube connected to the nebulization breathing end of the drug cup, a breathing mask connected to the corrugated flexible tube, and a reclining chair for patient use fitted to the bottom of the drug cup. The device also includes: A placement component, which is mounted on a recliner, is used to provide basic support for the medicine cup; The placement component includes a placement box, which is disposed on the armrest of the recliner; The drug delivery height adjustment component is installed on the placement box and is used to adapt the height of the medicine cup during drug delivery to the different lying positions of the elderly. It can adjust the delivery height of the corrugated hose to the breathing mask when delivering atomized particles, so that the atomized particles can flow smoothly in it. The drug delivery height adjustment assembly includes a sliding block that is slidably connected to the top of the placement box. An adjustment plate is rotatably connected to the sliding block. The inner side of the adjustment plate is fixed with drug cups of different diameters by multi-specification fasteners. The adjustment plate is fixed with angle snap-fit ​​fasteners at different tilt angles. A drug delivery distance adjustment component is installed on the placement box and is used to adjust the distance between the drug cup and the breathing mask to suit the elderly person's lying position.

[0006] Furthermore, the placement component also includes a snap-fit ​​groove, which is located at the bottom of the placement box. A rubber extrusion strip is fixedly connected inside the snap-fit ​​groove and fits against the armrest of the recliner. A locking plate is movably connected inside the snap-fit ​​groove via a pin, and the bottom of the locking plate is locked and secured by the bottom of the inner wall of the snap-fit ​​groove.

[0007] Furthermore, the multi-specification fixing component includes a fixing block, which is fixedly connected to the adjusting plate. A fixing sleeve is rotatably connected inside the fixing block, and a screw is threadedly connected inside the fixing sleeve. A support sleeve is fitted onto the end of the screw away from the fixing sleeve, and the screw rotates freely inside the support sleeve. A support arc plate is fixedly connected to the side of the support sleeve away from the screw. A rubber multi-point friction plate is fixedly connected to the inner side of the support arc plate, and the rubber multi-point friction plate contacts the surface of the medicine cup. A torsion spring is fixedly connected to the surface of the fixing sleeve, and the other end of the torsion spring is fixedly connected to the inside of the fixing block.

[0008] Furthermore, a support plate is fixedly connected to the bottom of the support arc plate, and the top of the support plate is in contact with the bottom of the medicine cup.

[0009] Furthermore, the angle locking component includes a circular plate, an octagonal insert rod is fixedly connected to the circular plate, an octagonal slot is provided on the adjusting plate, a pulling spring is fixedly connected to the circular plate, the outer side of the pulling spring is fixedly connected to the sliding block, and a limiting rod is fixedly connected to the circular plate, the limiting rod being slidably connected inside the sliding block.

[0010] Furthermore, the drug delivery height adjustment assembly also includes a limiting sleeve, which is fixedly connected to the circular plate. A hollow tube is rotatably connected to the inner side of the limiting sleeve, and a pull rod is slidably connected inside the hollow tube. The angle descent speed of the adjustment plate during adjustment is controlled by a damping decelerator inside the sliding block.

[0011] Furthermore, both the hollow tube and the pull rod are fixedly connected to touch rings, making it easier for the elderly to control the hollow tube and the pull rod to move inward simultaneously.

[0012] Furthermore, the damping deceleration component includes a damping spring, which is fixedly connected to the inner wall of the sliding block. A rubber damping ring is fixedly connected to the inner side of the damping spring, and the rubber damping ring is in contact with the rotational connection of the adjusting plate.

[0013] Furthermore, the drug delivery distance linkage adjustment component includes a limiting groove, which is formed on the top of the placement box. The sliding block is slidably connected inside the limiting groove. A moving plate is fixedly connected to the sliding block. An insert plate is slidably connected inside the moving plate. The insert plate is slidably connected inside the sliding block. A positioning toothed plate is fixedly connected to the inner wall of the limiting groove. A positioning toothed block is fixedly connected to the insert plate. The positioning toothed block and the positioning toothed plate mesh with each other. A fixing plate is fixedly connected to the insert plate. A reset spring is fixedly connected to the fixing plate. The other side of the reset spring is fixedly connected to the surface of the moving plate. Pulling rings are fixedly connected to both the pull rod and the hollow tube.

[0014] Furthermore, a limiting block is fixedly connected to the surface of the sliding block, and the limiting block is slidably connected inside the limiting groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In this invention, a placement component with a snap-fit ​​fixing structure is set on the armrest of a recliner to support the medication cup, transferring the weight of the medication cup from the breathing mask side to the recliner armrest or bed surface. This fundamentally avoids problems such as one-sided tilting and air leakage, strap slippage, and ear compression caused by the breathing mask being pulled. The snap-fit ​​groove, combined with a rubber extrusion strip and an adaptive clamping plate, can quickly adapt to different sizes of recliner armrests without measurement. It also supports flat use, enabling hands-free nebulization treatment throughout the entire process. This solves the pain point of elderly patients with hand tremors, Parkinson's disease, and osteoarthritis having difficulty maintaining support, and significantly improves treatment compliance. In this invention, based on the stable support of the placement box, the multi-angle adjustment and damping locking design of the drug delivery height adjustment component breaks through the limitation of existing devices that can only adjust the vertical angle of the liquid cup, accurately adapting to different lying positions such as semi-reclining, supine, and lateral recumbent. The angle adjustment of the adjustment plate ensures that the corrugated hose and the breathing mask maintain a smooth connection and natural curvature, eliminating the problem of tubing bends or excessive height differences disrupting the laminar flow delivery of the liquid. At the same time, the damping deceleration component can effectively suppress sudden angle changes and liquid sloshing during the adjustment process, and the angle locking structure of the octagonal plug can resist external force disturbances caused by the elderly turning over or touching their limbs, ensuring the stability of the liquid flow during nebulization, significantly improving the effective deposition rate of the liquid in the lungs, and ensuring the therapeutic effect. In this invention, based on the stable delivery of the nebulizer, the synchronous control design of the drug delivery distance linkage adjustment component solves the defect of existing devices where the relative distance between the drug cup and the breathing mask is fixed and cannot adapt to changes in their spatial geometry. Utilizing the linkage structure of the hollow tube and the pull rod, the displacement restriction of the sliding block can be automatically unlocked while adjusting the angle, achieving simultaneous height and distance adjustment without the need for step-by-step operation, thus reducing the operational threshold for elderly people with cognitive impairment. Combined with the self-locking design of the positioning toothed plate, the length of the nebulization delivery path can be flexibly adjusted according to the patient's height, lying position, and head and neck posture, dynamically maintaining the optimal delivery flow path and avoiding excessive traction on the breathing mask or bends and blockages in the tubing. This truly achieves a seamless wearing experience with one-time pre-adjustment and full-process locking, covering elderly groups with different body types and lying habits, and greatly improving individual adaptability.

[0018] 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.

[0019] like Figures 1 to 7 As shown, this invention provides an age-appropriate nebulized respiratory drug delivery device, including a compressor nebulizer 1, a drug cup 2 connected to the compressor nebulizer 1, the bottom of the drug cup 2 being connected to the nebulization outlet of the compressor nebulizer 1 via a flexible tube, a corrugated flexible tube 3 connected to the nebulization breathing end of the drug cup 2, a breathing mask 4 connected to the corrugated flexible tube 3, and a reclining chair 5 for patient use fitted to the bottom of the drug cup 2. The device also includes: Placement component 6 is mounted on the recliner 5 to provide basic support for the medicine cup 2; The placement component 6 includes a placement box 61, which is mounted on the armrest of the recliner 5. The drug delivery height adjustment component 7 is set on the placement box 61 to adapt the height of the drug cup 2 during drug delivery to the different lying positions of the elderly, and can adjust the delivery height of the corrugated hose 3 to the breathing mask 4 when delivering atomized particles. For example, it can be adjusted to be parallel to the breathing mask 4, so that the atomized particles can flow smoothly in it. The drug administration height adjustment component 7 includes a sliding block 71, which is slidably connected to the top of the placement box 61. An adjustment plate 72 is rotatably connected to the sliding block 71. The inner side of the adjustment plate 72 is fixed to the medicine cups 2 of different diameters by multi-specification fixing parts 73, and keeps the medicine cups 2 parallel to be placed for drug administration, so that the medicine will not tilt or spill due to changes in the elderly's lying posture. The adjustment plate 72 is fixed to the adjustment plate 72 at different tilt angles by angle snap fasteners 74. The drug delivery distance linkage adjustment component 8 is installed on the placement box 61 and is used to adjust the distance between the drug cup 2 and the breathing mask 4 to adapt to the lying position of the elderly, so that the path of transporting atomized particles between the drug cup 2 and the breathing mask 4 is adjustable and adaptable to different lying positions of the elderly.

[0020] Specifically, the compression nebulizer 1 can be placed independently on external surfaces such as beside the bed or on a table, without needing to move synchronously with the medication cup 2. It is connected to the medication cup 2 via a flexible tubing. The placement component 6 completely transfers the weight of the medication cup 2 from the breathing mask 4 to the reclining chair 5 or bed surface through an external support structure, fundamentally breaking the technical bias that fixed support is sufficient and eliminating the drawbacks of a single-sided cantilever pulling the mask, providing a physical basis for building a stable medication delivery path. The medication height adjustment component 7 can independently adjust the height and horizontal posture of the medication cup 2, accurately adapting to different reclining positions and ensuring that the corrugated tubing 3 maintains a smooth connection and natural curvature. The medication distance linkage adjustment component 8 can flexibly adjust the delivery path length between the medication cup 2 and the breathing mask 4, dynamically compensating for changes in spatial geometry caused by changes in body position, and is triggered in conjunction with angle adjustment operations, greatly simplifying the operation process. The three components work together to achieve a hands-free, multi-positional, and easy-to-operate age-appropriate nebulized respiratory medication effect.

[0021] like Figures 4 to 6As shown, the placement component 6 also includes a snap-fit ​​groove 62, which is located at the bottom of the placement box 61. A rubber extrusion strip 63 is fixedly connected inside the snap-fit ​​groove 62. The rubber extrusion strip 63 is attached to the armrest of the recliner 5. A locking plate 64 is movably connected inside the snap-fit ​​groove 62 via a pin. The bottom of the locking plate 64 is locked and secured by the bottom of the inner wall of the snap-fit ​​groove 62.

[0022] Specifically, the rubber compression strip 63 can flexibly press and tighten the armrests on different recliners 5, preventing the storage box 61 from slipping off the armrests of different sizes of recliners 5. The bottom of the locking plate 64 is locked by the bottom of the locking groove 62, so the locking plate 64 can only move upwards. When it contacts the armrest of the recliner 5, the locking plate 64 moves upwards to create space for the armrest to enter. After the armrest of the recliner 5 contacts and is continuously pressed against the rubber compression strip 63, the opening created by the locking plate 64 is again blocked by the locking plate 64 at the bottom of the locking groove 62. Therefore, the storage box 61 can be fixedly locked onto the armrests of different sizes of recliners 5 for use. Of course, the storage box 61 can also be used flat, such as when an elderly person is lying in bed; the storage box 61 can still be used flat for support. Disassembly is performed by reversing... Pushing the card plate 64 upwards creates a gap for the armrest of the recliner 5 to detach from the placement box 61. The card plate 64 is made of polyurethane and has elastic deformation capability. When the pulling force of the placement box 61 exceeds the bending threshold of the card plate 64, the card plate 64 will be forcibly bent to form an emergency gap for the armrest of the recliner 5 to be removed, allowing caregivers to forcibly remove the device. The card plate 64 can automatically reset after deformation without affecting subsequent use. This self-adaptive snap-fit ​​structure can be quickly assembled and disassembled without additional tools, adapting to armrests of different sizes and flat surfaces. It provides a stable bearing reference for the drug delivery height adjustment component 7 and the drug delivery distance linkage adjustment component 8 above, preventing the drug cup 2 from tilting and the tubing from pulling the breathing mask 4 due to the slippage of the placement box 61. It also provides a reliable external support for hands-free treatment throughout the entire process.

[0023] like Figures 1 to 3 As shown, the multi-specification fastener 73 includes a fastening block 731, which is fixedly connected to the adjusting plate 72. A fastening sleeve 732 is rotatably connected inside the fastening block 731. A screw 733 is threadedly connected inside the fastening sleeve 732. A support sleeve 734 is sleeved on the end of the screw 733 away from the fastening sleeve 732. The screw 733 rotates freely inside the support sleeve 734. A support arc plate 735 is fixedly connected to the side of the support sleeve 734 away from the screw 733. A rubber multi-point friction plate 736 is fixedly connected to the inner side of the support arc plate 735. The rubber multi-point friction plate 736 is in contact with the surface of the medicine cup 2. A torsion spring 737 is fixedly connected to the surface of the fastening sleeve 732. The other end of the torsion spring 737 is fixedly connected to the inside of the fastening block 731.

[0024] Specifically, the torsion spring 737, through its torsion support, engages with the fixed sleeve 732 and the screw 733 threaded inside the fixed sleeve 732, forming a symmetrical lateral support. The screw 733, moving within the fixed sleeve 732, pushes the supporting arc plate 735 and the rubber multi-point friction plate 736 to contact and secure different sizes of medicine cups 2 against their inner sides. This allows medicine cups 2 of different models and specifications to be positioned and used. This structure is compatible with clinically used medicine cups 2 of different diameters, improving the device's versatility. The rubber multi-point friction plate 736 increases the friction of the medicine cup 2. The torsion spring 737 provides elastic support to the fixed sleeve 732, which is rotatably connected inside the fixed block 731. When the medicine cup 2 is pulled during inhalation administration, it is supported by the arc plate 735. Supported by the fixing sleeve 732, the fixing sleeve 732 rotates inside the fixing block 731 to adapt to the angle adjustment of the medicine cup 2. However, during drug administration, the medicine cup 2 needs to remain vertically parallel so that the nebulizing element is continuously immersed in the medicine. When the fixing sleeve 732 rotates in the fixing block 731, it will simultaneously cause the torsion spring 737 to twist. The torsion spring 737 applies a circumferential rebound pre-tightening force to the fixing sleeve 732. When the patient pulls slightly or the corrugated tubing 3 is subjected to force due to changes in body position, the fixing sleeve 732 can overcome the resistance of the torsion spring 737 and undergo a slight adaptive deflection to buffer the pulling force. After the external pulling force disappears, the rebound force of the torsion spring 737 makes the fixing sleeve 732 return to the preset tilt angle, preventing the medicine cup 2 from tipping over due to accidental force, thereby ensuring that the nebulizing element is continuously immersed in the bottom area of ​​the medicine and ensuring the continuity of the nebulization process.

[0025] like Figure 3 As shown, a support plate 9 is fixedly connected to the bottom of the support arc plate 735, and the top of the support plate 9 is in contact with the bottom of the medicine cup 2.

[0026] Specifically, a lower limit ring is formed at the bottom of the medicine cup 2 by the support plate 9, which can support and lift the bottom of the medicine cup 2, forming an auxiliary support effect from the bottom. This is not just a simple side-clamping support for the medicine cup 2. The support plate 9 and the side support arc plate 735 form a double fixing structure of side clamping and bottom lifting. During the angle switching of the adjustment plate 72 and the back-and-forth movement of the sliding block 71, the vertical movement of the medicine cup 2 can be effectively prevented. Even if the patient's body position changes or the limb touches and vibrates, the medicine cup 2 can be kept horizontally stable, ensuring that the nebulizing element is continuously immersed in the medicine and ensuring that the nebulization process is not interrupted.

[0027] like Figures 4 to 7As shown, the angle locking component 74 includes a circular plate 741, an octagonal insert rod 742 fixedly connected to the circular plate 741, an octagonal slot 743 opened on the adjusting plate 72, a pulling spring 744 fixedly connected to the circular plate 741, the outer side of the pulling spring 744 being fixedly connected to the sliding block 71, and a limiting rod 745 fixedly connected to the circular plate 741, the limiting rod 745 being slidably connected inside the sliding block 71.

[0028] Specifically, by continuously pulling the spring 744, the circular plate 741 drives the octagonal insert 742 to be inserted into the octagonal slot 743 inside the adjusting plate 72, limiting the rotation angle of the adjusting plate 72 inside the sliding block 71. Multiple limiting rods 745 on the circular plate 741 prevent displacement caused by the angular twisting of the adjusting plate 72. Furthermore, the limiting rods 745 prevent the circular plate 741 from completely disengaging from the sliding block 71 when moving the octagonal insert 742. The multiple limiting rods 745 provide anti-twisting and anti-displacement effects. The octagonal insert 742 corresponds to different angle limits in the octagonal slot 743. During adjustment, after the circular plate 741 moves relative to the octagonal insert 742... The octagonal insert 742 is removed from the octagonal slot 743, at which point the angle of the adjustment plate 72 can be manually adjusted. After adjustment, the octagonal insert 742 and the circular plate 741 are pulled back to their original positions by the action of the pull spring 744 and continue to be inserted into the octagonal slot 743 to limit the angle of the adjustment plate 72. This plug-in locking structure automatically locks when released, without the need for additional locking operation, which is suitable for the operating habits of elderly patients. The octagonal multi-position positioning can accurately adapt to the height requirements of different lying positions. After locking, it can resist the external force disturbance of the patient turning over and the tube pulling, and avoid the tilting of the medicine cup 2 due to the angle deviation. Together with the double fixing structure of the medicine cup 2, it ensures the stability of the medicine posture during the nebulization process and provides angular support for the smooth delivery of the medicine mist.

[0029] like Figures 1 to 4 As shown, the drug delivery height adjustment assembly 7 also includes a limiting sleeve 75, which is fixedly connected to the circular plate 741. A hollow tube 76 is rotatably connected to the inner side of the limiting sleeve 75. A first limiting ring with an outer diameter larger than the inner diameter of the limiting sleeve 75 is fixedly sleeved on the outer side of one end of the hollow tube 76, so that the hollow tube 76 is rotatably connected to the inside of the limiting sleeve 75. A pull rod 77 is slidably connected inside the hollow tube 76. A second limiting ring with an outer diameter larger than the inner diameter of the limiting sleeve 75 is also provided at one end of the pull rod 77, so that the pull rod 77 is rotatably connected to the inside of the limiting sleeve 75. The sliding block 71 controls the downward and upward speeds of the adjustment plate 72 during adjustment through a damping deceleration component 78, so as to prevent the adjustment plate 72 from shaking due to excessive speed during adjustment.

[0030] Specifically, the large-diameter limiting rings on the hollow tube 76 and the pull rod 77 achieve axial limiting, allowing the hollow tube 76, the pull rod 77, and the limiting sleeve 75 to rotate relative to each other to adapt to angle adjustment without axial disengagement. This ensures the stable and reliable action of simultaneous double-sided squeezing and unlocking. The pull rod 77 and the hollow tube 76 can simultaneously squeeze the circular plates 741 on both sides inward, causing the two circular plates 741 to be controlled and simultaneously disengage the octagonal insert 742 from the octagonal slot 743. This allows for simultaneous angle adjustment of the two adjustment plates 72 on both sides, rather than adjusting them sequentially, maintaining synchronicity during adjustment. Simultaneous double-sided unlocking avoids tilting of the medicine cup 2 caused by single-sided adjustment, ensuring that the cup remains horizontal during angle adjustment and reducing the risk of spillage. At the same time, this synchronous control structure can also trigger the unlocking of the drug delivery distance linkage adjustment component 8, achieving one-step control of angle and distance adjustment. Combined with the slowing effect of the damping decelerator 78, the adjustment process is smooth and controllable, significantly reducing the difficulty of adjustment for elderly patients and improving the age-friendly experience.

[0031] like Figures 1 to 5 As shown, both the hollow tube 76 and the pull rod 77 are fixedly connected to a contact ring 10.

[0032] Specifically, when adjustment is needed, by actively moving the touch ring 10, the hollow tube 76 and the pull rod 77 can be controlled to move inward simultaneously, that is, the pull rod 77 moves into the hollow tube 76, which can control the circular plates 741 on both sides to move actively. The touch ring 10 increases the operating contact area, eliminating the need for precise pinching of small parts, making it suitable for elderly patients with tremors, osteoarthritis, and poor finger dexterity to apply force. The pressing and unlocking operation can be completed with one hand, further reducing the operation threshold and ensuring that elderly patients can independently complete parameter adjustment, achieving rapid pre-treatment preset.

[0033] like Figure 7 As shown, the damping deceleration component 78 includes a damping spring 781, which is fixedly connected to the inner wall of the sliding block 71. A rubber damping ring 782 is fixedly connected to the inner side of the damping spring 781, and the rubber damping ring 782 is in contact with the rotational connection of the adjusting plate 72.

[0034] Specifically, the rubber damping ring 782, driven by the damping spring 781, can increase the rotational damping at the rotational connection between the adjusting plate 72 and the sliding block 71, preventing the rotational connection between the adjusting plate 72 and the sliding block 71 from rotating too quickly. This structure can provide continuous buffering during angle adjustment, preventing the adjusting plate 72 from falling back quickly and causing impact when the elderly release their grip, and preventing the liquid in the medicine cup 2 from shaking violently and disrupting the laminar flow of the medicine mist. At the same time, it makes the angle fine-tuning more precise and controllable, making it easier for the patient to adjust the corrugated hose 3 to the optimal state of smooth docking with the breathing mask 4, eliminating tube bends and height differences, and ensuring the stable delivery of medicine mist particles from a fluid dynamics perspective.

[0035] like Figures 4 to 7 As shown, the drug delivery distance linkage adjustment component 8 includes a limiting groove 81, which is located on the top of the placement box 61. A sliding block 71 is slidably connected to the inside of the limiting groove 81. A moving plate 82 is fixedly connected to the sliding block 71. An insert plate 83 is slidably connected to the inside of the moving plate 82. The insert plate 83 is slidably connected to the inside of the sliding block 71. A positioning toothed plate 84 is fixedly connected to the inner wall of the limiting groove 81. A positioning toothed block 85 is fixedly connected to the insert plate 83. The positioning toothed block 85 and the positioning toothed plate 84 mesh with each other. A fixing plate 86 is fixedly connected to the insert plate 83. A reset spring 87 is fixedly connected to the fixing plate 86. The other side of the reset spring 87 is fixedly connected to the surface of the moving plate 82. Pulling rings 88 are fixedly connected to both the pull rod 77 and the hollow tube 76.

[0036] Specifically, the fixed plate 86 provides a stable force fulcrum for the reset spring 87, ensuring that the reset spring force is evenly applied to the insert plate 83, and ensuring that the insert plate 83 can smoothly reset after release, realizing reliable engagement and locking between the positioning tooth block 85 and the positioning tooth plate 84. The insert plate 83 is slidably connected to the inside of the sliding block 71 through a rectangular guide groove, ensuring the stability of the insert plate in driving the positioning tooth block 85 to engage with the positioning tooth plate 84. Furthermore, the positioning tooth block 85 slides in the rectangular guide groove under the drive of the insert plate 83, so as to adapt to the linkage. The distance the octagonal insert 742 moves out of the octagonal slot 743 is such that when the pull rod 77 and hollow tube 76 are adjusted inward, the pull ring 88 on the pull rod 77 and hollow tube 76 actively pulls the insert plate 83 away from the positioning tooth plate 84, causing the insert plate 83 to overcome the reset spring force of the reset spring 87 and temporarily disengage the positioning tooth block 85 from the positioning tooth plate 84 laterally. When the user no longer actively pulls the pull rod 77 and hollow tube 76, the insert plate 83 will continue to be pulled back by the force of the reset spring 87. The positioning toothed block 85 continues to engage with the positioning toothed plate 84 to prevent the sliding block 71 from sliding freely inside the limiting groove 81, thus improving the controllability of the sliding distance of the sliding block 71 inside the limiting groove 81. This linkage unlocking structure realizes the synchronous control of angle adjustment and distance adjustment, eliminating the need for step-by-step unlocking and adjustment, and simplifying the operation process. The multi-tooth meshing locking of the positioning toothed plate 84 has high precision and automatically locks when released, avoiding deviation in the delivery path length and ensuring that the spatial geometric relationship between the drug cup 2 and the breathing mask 4 is always in the optimal state. With the corrugated hose 3, it can flexibly adapt to patients of different heights and lying positions, preventing the tubing from excessively pulling on the breathing mask 4 or bending and blocking it, greatly improving individual adaptability. The automatic sliding of the sliding block 71 can dynamically compensate for the curvature of the corrugated hose 3, ensuring that the tubing is always in a natural and relaxed state, neither excessively bending to increase airflow resistance nor excessively stretching to cause rebound force to pull on the breathing mask 4. From a fluid dynamics perspective, this ensures the laminar delivery of drug mist particles and the effective deposition rate in the lungs.

[0037] like Figures 5 to 7 As shown, a limiting block 11 is fixedly connected to the surface of the sliding block 71, and the limiting block 11 is slidably connected inside the limiting groove 81.

[0038] Specifically, by limiting the vertical movement of the sliding block 71 within the limiting groove 81 through the limiting block 11, the sliding block 71 can be kept stable within the limiting groove 81. The limiting block 11 and the limiting groove 81 work together to form an all-directional limiting, preventing the sliding block 71 from tilting or deflecting when moving back and forth. This ensures that the posture of the adjusting plate 72 and the medicine cup 2 remains stable, preventing the medicine cup 2 from tilting and spilling due to the shaking of the sliding block 71. At the same time, it ensures that the positioning tooth block 85 and the positioning tooth plate 84 are always precisely engaged, avoiding problems such as tooth disengagement and jamming, and improving the smoothness of distance adjustment and locking reliability.

[0039] The working principle of this invention is as follows: First, the locking groove 62 at the bottom of the placement box 61 is aligned with the armrest of the recliner 5 and pushed horizontally into place. The armrest pushes the locking plate 64 upward around the pin axis to open the entrance. After being fully pushed in, the rubber extrusion strip 63 is compressed to form a flexible anti-slip clamp. The locking plate 64 falls back under its own weight and is limited by the bottom of the locking groove 62 to form a one-way lock, thus quickly fixing the placement box 61. For bedridden scenarios, the placement box 61 can also be placed directly on the bed or table. This installation operation can be completed by the elderly patient himself or by family members or caregivers in advance. Then, place the medicine cup 2 between the two supporting arc plates 735, with the bottom supported on the supporting plate 9; rotate the screw 733 inside the fixing sleeve 732 to push the supporting arc plate 735 to move radially closer, and press against the wall of the medicine cup 2 through the rubber multi-point friction plate 736, forming a double clamping structure of side pressing and bottom lifting, which can be adapted to clinical medicine cups 2 of different diameters. Posture adjustment is also completed before treatment. With one hand, the touch ring 10 is pinched inwards, causing the hollow tube 76 and pull rod 77 to retract inwards simultaneously. This, through the limiting sleeves 75 at both ends, pushes the two circular plates 741 to move inwards synchronously, causing the octagonal insert rod 742 to disengage from the octagonal slot 743 of the adjustment plate 72, thus unlocking the angle. Simultaneously, the pull rod 77 and the pull ring 88 on the hollow tube 76 simultaneously move the insert plate 83 outwards, overcoming the elasticity of the reset spring 87 to disengage the positioning tooth block 85 from the positioning tooth plate 84, thus unlocking the distance. At this point, the adjustment plate 72 can be rotated to adjust the pitch according to the elderly person's desired semi-reclining, supine, or lateral lying position. The height is adjusted by moving the sliding block 71 to adjust the front and rear distance, so that the corrugated hose 3 remains in a naturally extended state, forming a smooth delivery path with the breathing mask 4. During the adjustment of the adjusting plate 72, the damping spring 781 pushes the rubber damping ring 782 to apply continuous damping to the rotating contact surface, so as to avoid the drug solution shaking caused by the adjusting plate 72 adjusting too fast. After the adjustment is in place, the contact ring 10 is released, the spring 744 is pulled to drive the octagonal plug 742 to reset the locking angle, and the reset spring 87 drives the positioning tooth block 85 to reset the locking distance, so that the entire process can be locked with one pre-adjustment, and no further adjustment is required during subsequent treatment. After the preset is completed, the elderly patient only needs to lie down, put on the breathing mask 4 and start the compressor nebulizer 1 placed independently next to the bed or chair to start the nebulization treatment. There is no need to hold the medicine cup 2 throughout the process, and the hands are completely free. The nebulized medium generated by the compressor nebulizer 1 is delivered to the medicine cup 2 through the bottom hose. The nebulized medicine particles are smoothly delivered to the breathing mask 4 through the pre-adjusted corrugated hose 3. Since the entire weight of the medicine cup 2 is supported by the external placement box 61, the unilateral pulling effect of the traditional side-hanging structure on the breathing mask 4 is completely eliminated. This avoids the problems of the breathing mask 4 tilting up and leaking air, the strap slipping off and pressing on the auricle from the root, and ensures the wearing comfort and sealing during the long nebulization treatment course. Meanwhile, the pre-adjusted and optimized delivery path is free of bends and excessive height differences, allowing the atomized particles to maintain a uniform and smooth flow, adapting to the breathing rhythm of the elderly in a lying position, effectively improving the efficiency of drug atomization in the lungs. During treatment, the rigid locking structure of the octagonal plug 742 can resist external force disturbances caused by the patient turning over or touching the tubing, maintaining the stability of the medication cup 2. The elastic torsional support of the torsion spring 737 can counteract the slight shaking caused by the tubing pull and drive the medication cup 2 to automatically return to the correct position, ensuring that the atomizing element is continuously immersed in the medication, ensuring that the atomization process is continuous and uninterrupted. After treatment, push the card plate 64 upward to form a removal notch, and the placement box 61 can be removed from the armrest of the recliner 5 to complete normal disassembly.
