Description
A cavity aerosol drug delivery device for elderly care Technical Field
[0001] This invention relates to the field of aerosol drug delivery technology, and in particular to a cavity aerosol drug delivery device for elderly care. Background Technology
[0002] Inhaled aerosols are formulations containing a drug solution, suspension, or emulsion, along with a suitable propellant or liquefied propellant mixture, packaged together in a pressure-resistant container with a metering valve system and a certain pressure. When used, the contents are sprayed out as a mist using the pressure of the propellant and inhaled through the mouth, depositing in the lungs. They are also commonly referred to as pressurized metered-dose inhalers.
[0003] A search revealed Chinese invention patent publication number CN116764039B, which discloses an intracavitary aerosol drug delivery device for elderly care. The device includes a main body with a detachable aerosol canister inside. A spray valve for inhaling medication from the aerosol canister is located on the upper side of the main body. A main unit cover is fixedly mounted on the left side of the spray valve, and a fixing cover is fixedly mounted on the left side of the main unit cover. This intracavitary aerosol drug delivery device for elderly care opens the patient's mouth by placing two support parts against the upper and lower gums of the patient's mouth, respectively. A support rod moves the support parts relative to each other, facilitating medication delivery by caregivers. This addresses the problem of elderly patients being unable to open their mouths independently, resulting in low drug delivery efficiency and improving treatment effectiveness, thus promoting faster recovery for elderly patients.
[0004] Existing drug delivery devices are complex to operate when replacing storage tanks or connecting pipelines, which can easily lead to air leaks or drug contamination. During pressurization, the pressure difference between the inside and outside may cause drug backflow or air pollution. During drug delivery, pressure fluctuations may cause backflow, affecting dosage accuracy. Furthermore, the lack of a sealing structure between the drug storage device and the nebulizer results in a high risk of cross-infection during the use of the drug storage device, and the drug is easily exposed to environmental contamination.
[0005] Therefore, the existing cavity aerosol delivery device for elderly care cannot meet the needs of actual use, so there is an urgent need for improved technology on the market to solve the above problems. Summary of the Invention

[0017] This invention has the following beneficial effects: 1. Through the connecting structure set on the base plate, the storage structure can be quickly installed and replaced during use via the connecting frame. Furthermore, the limiting structure prevents the storage box from falling off due to accidental contact by the patient. The limiting structure on the connecting structure, through the dynamic cooperation of the limiting ball and the locking groove, combined with the elastic deformation of the limiting spring, achieves automatic locking between the storage structure and the connecting structure. This allows installation to be completed simply by rotating the storage box, without the need for complex tools or additional fasteners, reducing operational difficulty. It is particularly suitable for the frequent medication changes required in elderly care scenarios. The storage structure on the connecting structure enables independent sealed storage of medications during use. The connecting pipe and locking groove enable quick installation and removal of the storage structure and ensure stability after installation. The pressurization structure on the base plate transmits the airflow delivered through the air intake connecting structure during use. The system provides dual protection for the water delivery pipe by combining the dynamic sealing of the lower sealing structure with the static sealing of the water delivery pipe. This effectively prevents liquid backflow and cross-contamination risks. The sealing structure on the pressurization structure, driven by air pressure, forms an adaptive sealing system with the sealing block and sealing spring. When air is injected, the compression spring opens the channel; when air is stopped, the spring resets and closes the air delivery pipe, preventing backflow of the drug and contamination from external air, ensuring drug purity and dosage accuracy. Furthermore, the sealing block and limiting groove form a pressure buffer space, automatically releasing pressure when the internal and external pressure difference is too large, preventing mucosal damage caused by overpressure. This is particularly suitable for drug delivery to sensitive cavities. The connection structure on the base plate allows for easy connection of the external air intake pipe to the air intake pipe during use. The air intake pipe and pressurization structure form a sealed space, limiting the airflow direction while facilitating the airflow to push the sealing block.
[0018] 2. This invention utilizes an infusion structure mounted on a base plate. During use, the liquid enters the delivery pipe through the infusion pipe and installation pipe. The resistance of the flow-blocking structure overcomes the resistance of the water flow, achieving on-demand quantitative delivery and reducing human error. The flow-blocking structure on the infusion structure, through a flow-blocking spring and block forming a one-way valve, opens the channel when the liquid flows and returns to its original position to prevent backflow when the flow stops. The delivery structure on the base plate allows for the installation and placement of the nebulizer and adjustment structures. The threaded mounting groove on the mask enables quick installation of the nebulizer. The mask provides full coverage of the face and has a soft contact surface. Combining an adjustable-length delivery tube, it balances comfort and airtightness, reducing drug leakage and improving patient tolerance. The nebulizer delivery structure features a threaded quick-release design between the delivery tube and the mask, allowing for on-demand combination of nebulizer lengths. This enables the nebulizer to flexibly adapt to different treatment scenarios, such as nasal / oral administration, enhancing the device's versatility. The adjustable support structure, with its sliders, connecting rods, and support pads, can be manually extended via an adjustable motor, assisting patients with difficulty opening their mouths and resolving the inefficiency caused by low patient cooperation in traditional drug delivery methods.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0024] Please refer to Figures 1-6. This embodiment is a cavity aerosol drug delivery device for elderly care, including a base plate 1. A connecting structure 2 is fixedly connected to the lower end face of the base plate 1. A storage structure 3 is threadedly connected to the inner cavity of the connecting structure 2. A pressurizing structure 4 is fixedly connected to one side of the upper end face of the inner cavity of the connecting structure 2. An infusion structure 6 is fixedly connected to the other side of the upper end face of the inner cavity of the connecting structure 2. An air inlet connecting structure 5 is fixedly connected to the side of the upper end face of the connecting structure 2 that matches the pressurizing structure 4. A delivery structure 7 is connected to the side of the upper end face of the connecting structure 2 that matches the infusion structure 6. The inner cavity of the delivery structure 7, away from the connecting structure 2, is threadedly connected to... The device includes an atomizing drug delivery structure 8, a delivery structure 7 with symmetrically arranged adjustment structures 9, and a support structure 10 symmetrically sliding between the two adjustment structures 9. The connecting structure 2 includes a connecting frame 21 fixedly connected to the lower end face of the base plate 1. Limiting grooves 22 are evenly opened on the inner side wall of the connecting frame 21. A limiting structure 23 is fixedly connected to the inner cavity of the limiting groove 22. A storage structure 3 is threadedly connected to the inner cavity of the connecting frame 21. Through the connecting structure 2 on the base plate 1, the storage structure 3 can be quickly installed and replaced during use via the connecting frame 21. The limiting structure 23 prevents the storage box 33 from falling off due to accidental contact by the patient.
[0025] Furthermore, the limiting structure 23 includes a limiting spring 231 fixedly connected to the inner wall of the limiting groove 22. A guide post 232 is fixedly connected to the inner side of the limiting spring 231 near the limiting groove 22. A limiting ball 233 is slidably connected to the outer surface of the guide post 232. The limiting spring 231 is driven between the connecting frame 21 and the limiting ball 233. Through the limiting structure 23 on the connecting structure 2, the storage structure 3 and the connecting structure 2 are automatically locked in use by the dynamic cooperation between the limiting ball 233 and the snap-fit groove 32, combined with the elastic deformation of the limiting spring 231. This allows the installation to be completed simply by rotating the storage box 33, without the need for complicated tools or additional fasteners, reducing the difficulty of operation. This is especially suitable for the needs of frequent medication changes in elderly care scenarios.
[0026] Furthermore, the storage structure 3 includes a connecting tube 31 threaded into the inner cavity of the connecting frame 21. The outer surface of the connecting tube 31 is evenly provided with snap-fit grooves 32 that match the limiting balls 233. The number of snap-fit grooves 32 matches the number of limiting structures 23. The lower end face of the connecting tube 31 is fixedly connected to a storage box 33. Through the storage structure 3 on the connecting structure 2, the medicine can be independently and sealed during use. In addition, the quick loading and unloading of the storage structure 3 and the stability after installation are achieved through the connecting tube 31 and the snap-fit grooves 32.
[0027] Furthermore, the pressurization structure 4 includes an air supply pipe 41 fixedly connected to one side of the lower end face of the base plate 1. The inner cavity of the air supply pipe 41 penetrates the inner cavity of the base plate 1 and is interconnected. An air supply sleeve 42 is fixedly connected to the lower part of the outer surface of the air supply pipe 41. A sealing structure 43 is fixedly connected to the lower end of the inner cavity of the air supply sleeve 42. Through the pressurization structure 4 on the base plate 1, the airflow delivered through the air inlet connection structure 5 is transmitted to the inner cavity of the storage structure 3 during use. Then, the dynamic sealing of the sealing structure 43 at the lower end of the air supply pipe 41 and the static sealing of the water supply pipe 63 form a double protection, effectively avoiding the risk of liquid backflow and cross-contamination. A sealing frame 431 is fixedly connected to the lower end of the inner cavity of the sealing structure 43. A sealing spring 432 is fixedly connected to the upper end face of the device. A sealing block 433 is fixedly connected to the upper end of the sealing spring 432. The outer surface radius of the sealing block 433 is larger than the inner cavity radius of the gas delivery tube 41. Through the sealing structure 43 on the pressurization structure 4, the sealing block 433 and the sealing spring 432 form an adaptive sealing system during use by air pressure. When gas is injected, the spring is compressed to open the channel. When gas is stopped, the spring resets and closes the gas delivery tube 41, thereby preventing backflow of the drug liquid and external air pollution, ensuring the purity of the drug and the accuracy of the dosage. Furthermore, the sealing block 433 and the limiting groove 22 form a pressure buffer space. When the pressure difference between the inside and outside is too large, the pressure is automatically released to prevent mucosal damage caused by overpressure. It is especially suitable for drug delivery in sensitive cavities.
[0028] Furthermore, the air intake connection structure 5 includes an air intake pipe 51 fixedly connected to the upper end face of the base plate 1 above the pressurization structure 4. A connecting pipe 52 is fixedly connected to the upper part of the outer surface of the air intake pipe 51. A threaded groove 53 is fixedly connected to the upper part of the inner cavity of the connecting pipe 52. The inner cavity of the air intake pipe 51 is connected to the inner cavity of the air supply pipe 41. Through the connection structure 5 on the base plate 1, it is convenient for personnel to connect the external air intake pipe to the air intake pipe 51 during use. A sealed space is formed between the air intake pipe 51 and the pressurization structure 4, thus limiting the airflow direction and facilitating the airflow to push the sealing block 433.
[0029] Furthermore, the infusion structure 6 includes an installation pipe 61 fixedly connected to the lower part of the base plate 1 away from the pressurization structure 4. A flow-blocking structure 62 is fixedly connected to the upper end of the inner cavity of the installation pipe 61, and a water delivery pipe 63 is fixedly connected to the lower end of the inner cavity of the installation pipe 61. Through the infusion structure 6 on the base plate 1, water enters the delivery pipe 71 through the water delivery pipe 63 and the installation pipe 61 during use. The resistance of the flow-blocking structure 62, driven by the water flow, enables on-demand quantitative delivery, reducing human error. The flow-blocking structure 62... The system includes a flow-blocking frame 621 fixedly connected to the upper part of the inner cavity of the installation pipe 61. A flow-blocking spring 622 is fixedly connected to the middle of the lower end face of the flow-blocking frame 621. A flow-blocking block 623 is fixedly connected to the lower part of the flow-blocking spring 622. The outer surface radius of the flow-blocking block 623 is larger than the inner cavity radius of the water delivery pipe 63. Through the flow-blocking structure 62 on the infusion structure 6, the flow-blocking spring 622 and the flow-blocking block 623 form a one-way valve structure during use. When the liquid flows, the spring is compressed to open the channel, and when it stops, the spring returns to its original position to block the backflow.
[0030] Furthermore, the delivery structure 7 includes a delivery pipe 71 fixedly connected to the upper surface of the base plate 1 near the infusion structure 6. The inner cavity of the delivery pipe 71 penetrates the base plate 1 and communicates with the inner cavity of the mounting pipe 61. A mounting bracket 72 is symmetrically fixedly connected to the upper surface of the base plate 1 away from the air inlet connection structure 5, with the delivery pipe 71 as the center line. A V-shaped connecting bracket 73 is fixedly connected to the upper end of the mounting bracket 72. A face mask 74 is fixedly connected to the V-shaped connecting bracket 73 away from the air inlet connection structure 5. The middle of the left end face of the inner cavity of the face mask 74 is... A threaded mounting groove is provided that communicates with the inner cavity of the delivery tube 71. The nebulizer structure 8 is threadedly connected to the inner cavity of the threaded mounting groove. During use, the nebulizer structure 8 and the adjustment structure 9 are installed and placed through the delivery structure 7 on the base plate 1. The nebulizer structure 8 is then quickly installed through the threaded mounting groove on the mask 74. The mask 74 covers the face and has a soft contact surface. Combined with the adjustable length delivery tube, it takes into account both comfort and airtightness, reduces drug leakage and improves patient tolerance.
[0031] Furthermore, the nebulized drug delivery structure 8 includes a delivery tube 2 81 threadedly connected to the inner cavity of the threaded mounting groove. The end of the delivery tube 2 81 away from the mask 74 is fixedly connected to the nebulization module 82. The nebulized drug delivery structure 8 can be configured in several ways according to the required length. Through the nebulized drug delivery structure 8 on the delivery structure 7, the delivery tube 2 81 and the mask 74 adopt a threaded quick-release design during use, which supports the combination of the length of the nebulized drug delivery structure 8 as needed. This allows the nebulized drug delivery structure 8 to flexibly adapt to different treatment scenarios such as nasal / oral drug delivery, improving the versatility of the device.
[0032] Furthermore, the adjustment structure 9 includes a sliding frame 91 symmetrically fixedly connected to the left end face of the inner cavity of the mask 74. A rotating rod 92 is rotatably connected to the inner cavity of the sliding frame 91. Two sections of threads in opposite directions are symmetrically opened on the outer surface of the rotating rod 92. Adjustment motors 93 are fixedly connected to the lower part of the sliding frame 91 in the inner cavity of the mask 74. The output end of the adjustment motor 93 passes through the sliding frame 91 and is fixedly connected to the rotating rod 92. A support structure 10 is symmetrically arranged in the inner cavity of the sliding frame 91. A control module 94 is fixedly connected to the lower part of the outer surface of the mask 74. The two adjustment motors 93 are electrically connected to the control module 94. Through the adjustment structure 9 on the conveying structure 7, the support structure 10 is installed and placed during use. Then, the control module 94 drives the adjustment motors 93 to separate the slider 101. The support pad 104 is expanded through the linkage mechanism, thereby solving the problem of drug administration difficulties caused by insufficient oral muscle strength in disabled elderly people and reducing physical damage caused by manual prying of the mouth.
[0033] Furthermore, the support structure 10 includes a slider 101 slidably connected to the inner cavity of the sliding frame 91, a rotating rod 92 passing through the slider 101 and threadedly connected, a connecting rod 102 fixedly connected between the two sliders 101, a support plate 103 fixedly connected to the end of the connecting rod 102 away from the mask 74, and a support pad 104 fixedly connected to the side of the two support plates 103 away from each other. By adjusting the support structure 10 on the structure 9, the slider 101, connecting rod 102 and support pad 104 in the support structure 10 can be driven to unfold by adjusting the motor 93 during use, which helps patients with difficulty opening their mouths to passively open their mouths, solving the problem of low efficiency caused by low patient cooperation in traditional drug administration methods.
[0034] Working principle: During operation, the inner cavities of storage structure 3 and connecting structure 2 are mutually aligned. At this time, the storage box 33 is rotated, and the connecting pipe 31, which is fixedly connected to the storage box 33, rotates. Since the limiting structure 23 is located within the limiting groove 22, when the connecting pipe 31 rotates, the limiting ball 233 retracts along the guide post 232 into the limiting groove 22, and simultaneously the limiting spring 231 retracts, thus connecting the connecting pipe 31 and the connecting frame 21. At this time, the limiting spring 231 extends, so the limiting ball 233 slides outward along the guide post 232, causing the limiting ball 233 to engage in the locking groove 32, thus achieving the mutual installation of storage structure 3 and connecting structure 2. At this time, the external... The air pipe is threaded into the groove 53, thus connecting the air inlet pipe and the air inlet pipe 51. External air is then injected into the inner cavity of the storage tank 33 through the air inlet pipe and the air inlet pipe 51. Due to the air pressure, the sealing block 433 slides downwards, causing the sealing spring 432 to contract, thereby increasing the air pressure inside the storage tank 33. Similarly, when the air injection stops, the sealing spring 432 extends, causing the sealing block 433 to slide upwards, sealing the lower end of the air supply pipe 41. This prevents backflow or air pollution caused by the pressure difference between the inside and outside of the storage structure 3. The increased air pressure inside the storage tank 33 allows the storage tank 33 to store medicines or liquids, which are then transported through the water supply pipe 63 and the installation pipe 6. 1. The medication enters the first delivery pipe 71. Due to the water flow, the flow-blocking block 623 slides upward, causing the flow-blocking spring 622 to contract. Therefore, the medication enters the first delivery pipe 71 through the installation pipe 61 and is then transported to the atomizing drug delivery structure 8. When operation stops, the flow-blocking spring 622 extends, causing the flow-blocking block 623 to slide downward, thus sealing the water delivery pipe 63 and preventing backflow of the medication inside the first delivery pipe 71. When pressurized, the medication is delivered through the first delivery pipe 71 and the mask 74 to the second delivery pipe 81. The medication is then atomized by the atomizing module 82. Further, when administering medication to the patient, the dosage is adjusted according to the patient's actual condition and usage needs. The nebulizing drug delivery structure 8 of corresponding length is connected to the threaded mounting groove on the mask 74 via the delivery tube 81, thereby enabling quick assembly and disassembly of the nebulizing drug delivery structure 8. When administering drug to the cavity, the mask 74 is placed over the patient's face, while the support structure 10 is located between the patient's upper and lower jaws. When the patient has difficulty opening and closing their mouth, the control module 94 is activated, causing the output of the adjusting motor 93 to rotate. As a result, the rotating rod 92 rotates, causing the sliders 101 on both sides to move away from each other. Consequently, the connecting rod 102, the support plate 103, and the support pad 104 move away from each other, thus assisting the patient in opening their mouth. This facilitates the nebulizing drug delivery structure 8 in administering nebulized drug to the patient's mouth.
