Description

Technical Field

[0001] The invention belongs to the technical field of aerosol drug delivery, and in particular relates to a cavity aerosol drug delivery device for elderly care. Background Art

[0002] Inhalation aerosol refers to a drug-containing solution, suspension or emulsion, which is sealed together with a suitable propellant or liquefied mixed propellant in a pressure-resistant container with a metered valve system and a certain pressure. When used, the pressure of the propellant is used to spray the contents in the form of mist, which is inhaled orally and deposited in the lungs. It is also commonly called a pressure-metered inhaler.

[0003] At present, the existing aerosol drug delivery devices still have the following problems during use: when the elderly administer drugs to the cavity, they usually use natural cavities to administer drugs to the human body. When using natural cavities to administer drugs to the human body, due to the existence of elderly patients with severe airway restriction or poor cooperation, it is difficult for the elderly patients' mouths to open by themselves, resulting in the drug not being accurately delivered to the position where the patient needs to be administered, that is, the accuracy of the drug delivery position is poor, resulting in low drug delivery efficiency and low drug utilization rate, resulting in the failure to achieve the ideal treatment effect, which is not conducive to the elderly patients' recovery as soon as possible; therefore, there are deficiencies and it cannot meet the patients' use needs. Therefore, it is necessary to further improve.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a cavity aerosol drug delivery device for elderly care is provided, in order to achieve a more practical purpose. Summary of the Invention

[0010] Furthermore, an inner groove is provided on one side of the support portion, a groove is provided on the inner wall of the inner groove, and a plurality of movable parts are provided on the inner wall of the groove, and a connecting spring is provided between the movable parts and the inner wall of the groove.

[0011] By adopting the above structure, the two supporting parts are respectively placed against the upper gum and lower gum of the patient's mouth, so that the gum and the movable part are in contact with each other. At the same time, the cooperation between the connecting spring and the movable part is utilized to further improve the stability of the supporting part when in contact with the patient's gum.

[0019] Furthermore, an iron sleeve is provided on the outside of the driving shaft and on the left side of the fixing ring, and an electromagnet is provided on the inner wall of the protective component and on the outside of the iron sleeve;

[0020] Wherein, the control switch is electrically connected to the electromagnet.

[0021] By adopting the above structure, the electromagnet is energized to generate magnetism, thereby limiting its speed and stopping its operation, thereby avoiding damage to the oral cavity of the elderly patient when the drive shaft stalls, and further improving the safety performance of the equipment.

[0022] Furthermore, a plurality of guide balls for guiding the installation of the aerosol can are provided on the inner wall of the main body, and a mounting spring is provided between the guide balls and the inner wall of the main body, and the side of the guide balls away from the mounting spring is in contact with the aerosol can.

[0025] Wherein, a rack is fixedly provided on the outer side of the limiting sleeve.

[0029] By adopting the above structure, the aerosol can is clamped by the clamping plate to fix it in position, and the suction cup is in contact with the aerosol can to form a negative pressure state inside the suction cup, which can effectively improve the suction force of the suction cup on the aerosol can, further ensure the stability of the suction cup in clamping the aerosol can, and achieve the purpose of automatic clamping and fixing through this arrangement.

[0030] Beneficial effects

[0031] Compared with the prior art, the present invention provides a cavity aerosol drug delivery device for elderly care, which has the following beneficial effects:

[0032] 1. The cavity aerosol drug delivery device for elderly care, which respectively presses two supporting parts against the upper and lower gums of the patient's mouth, utilizes the rebound force of the connecting spring to promote the stability of the movable part when it effectively contacts the gums of the patient's mouth, and utilizes the supporting rod to drive the supporting parts to move relative to each other, thereby achieving the purpose of opening the mouth of the elderly patient, facilitating the nursing staff to administer drug treatment to the elderly patient, solving the problem that the elderly patient's mouth is difficult to open on its own, resulting in low drug delivery efficiency, further improving the treatment effect on the elderly patient, and facilitating the elderly patient's recovery as soon as possible.

[0033] 2. The cavity aerosol drug delivery device for elderly care places the atomizer tube and the atomizer head into the oral cavity of the elderly patient, moves the atomizer head to the designated drug delivery area, extracts the medicine in the aerosol tank through the spray valve, and utilizes the coordinated action of the atomizer tube and the atomizer head to spray the medicine into the patient's cavity for effective treatment. The setting of the atomizer tube makes it easy for the drug delivery device to be arbitrarily shaped to conform to the shape of the natural cavity of the human body, and delivers the medicine to the required position, thereby improving the accuracy of drug delivery, ensuring the treatment effect, and further enhancing the practical performance of the equipment.

[0034] 3. The cavity aerosol drug delivery device for elderly care effectively guides the aerosol can through the guide ball, which is conducive to the installation of the aerosol can. At the same time, the clamping plate is driven by the clamping rod to clamp the aerosol can and fix it in position. The suction cup is in contact with the aerosol can to form a negative pressure state inside the suction cup, which can effectively enhance the suction force of the suction cup on the aerosol can and further ensure the stability of the suction cup's clamping of the aerosol can. Through this setting, the device achieves the purpose of automatic clamping and fixing without the need for an additional fixing structure. It is simple to operate and easy to use.

[0035] 4. This cavity aerosol drug delivery device for elderly care, when the drive shaft stalls, uses the drive shaft to drive the fixed ring to rotate rapidly, and due to the centrifugal force when the fixed ring rotates, the centrifugal part pulls the centrifugal spring to move. As the centrifugal part moves outward and starts the control switch, and transmits electrical energy to the electromagnet, the electromagnet is energized to generate magnetism, and uses this magnetism to generate suction on the iron sleeve, thereby limiting its speed and stopping it, avoiding damage to the elderly patient's oral cavity due to the stall of the drive shaft, and further improving the safety performance of the equipment.

[0036] 5. The cavity aerosol drug delivery device for elderly care sprays the liquid medicine at high pressure through the nozzle, and uses the high-pressure sprayed liquid medicine to impact the leak-proof plate, prompting the leak-proof plate and the fixed block to separate from each other, and allowing the liquid medicine to enter the uniform mechanism along the gap separating the leak-proof plate and the fixed block. The uniform mechanism can make the sprayed liquid medicine more uniform and the atomization effect better. After the nozzle has finished spraying the liquid medicine, the tension of the elastic member is used to pull the leak-proof plate and the fixed block to form a closed state, which can effectively prevent the dripping of the liquid medicine and further improve the use effect of the atomizer head.

[0065] The specific usage and function of this embodiment are as follows:

[0066] Working principle: At present, the elderly usually use natural cavities to administer medicine to the human body. When in use, the designated aerosol can 17 is installed and the aerosol can 17 is placed from the bottom of the main body 1. During the placement process, the aerosol can 17 contacts the guide ball 18. The guide ball 18 effectively guides the aerosol can 17, which is beneficial to the installation of the aerosol can 17. At the same time, the aerosol can 17 is brought into contact with the limiting sleeve 19 and the limiting sleeve 19 is pushed upward. At the same time, the outer rack is used to contact with the guide ball 18. The movable gear plate 201 is meshed with each other for transmission, and the movable connecting rod 202 is used to drive the clamping rod 21 to move. The clamping rod 21 drives the clamping plate 22 to clamp the aerosol can 17 and fix it in position. The suction cup 221 is in contact with the aerosol can 17, so that a negative pressure state is formed inside the suction cup 221, which can effectively increase the suction force of the suction cup 221 on the aerosol can 17, further ensuring the stability of the suction cup 221 in clamping the aerosol can 17. Through this arrangement, the purpose of automatic clamping and fixing is achieved.

[0067] And for elderly patients with severe airway restriction or poor coordination, the two support parts 11 are respectively pressed against the upper gum and lower gum of the patient's mouth, so that the gum and the movable part 112 are in contact with each other, and the movable part 112 is pushed to squeeze the connecting spring 113, and the rebound force of the connecting spring 113 is used to push the movable part 112 to effectively contact the gum of the patient's mouth, further improving the stability of the support part 11 when in contact with the patient's gum; at the same time, the control panel 5 is used to start the drive motor 7, and the drive motor 7 generates kinetic energy to drive the drive shaft 71 and the worm 8 to rotate. As the worm 8 rotates and engages with the two worm gears 101 for transmission, the two worm gears 101 are caused to rotate in opposite directions, and the worm gear 101 rotates while driving the linkage rod 102 to move synchronously, and at the same time, the linkage rod 102 is driven to move synchronously, and the linkage rod 102 is driven to move synchronously, and the linkage rod 102 is driven to move synchronously, and the linkage rod 102 is driven to move synchronously, and the linkage rod 102 is driven to move synchronously, and the linkage rod 102 is driven to move synchronously, and the linkage rod 102 is driven to move synchronously, and the linkage rod 102 is driven to move synchronously, and the linkage rod 102 is driven to move synchronously, and the linkage rod 102 is driven to rotate ... The support rod 103 drives the support part 11 to move relative to each other, thereby achieving the purpose of opening the oral cavity of the elderly patient, which is beneficial for the nursing staff to administer medication to the elderly patient and is beneficial for the elderly patient to recover as soon as possible; and when the oral cavity is opened, the atomizing tube 12 and the atomizing head 121 are placed in the oral cavity of the elderly patient, and the atomizing head 121 is moved to the designated medication area, the medicine in the aerosol tank 17 is extracted through the medicine spraying valve 2, and the cooperation of the atomizing tube 12 and the atomizing head 121 is utilized to spray the medicine into the patient's cavity for effective treatment. Moreover, the arrangement of the atomizing tube 12 facilitates the drug delivery device to conform to the shape of the natural cavity of the human body and to deliver the medicine to the required position, thereby improving the accuracy of drug delivery by the drug delivery device, ensuring the therapeutic effect, and further improving the practical performance of the device.

[0068] The liquid medicine is transferred to the nozzle 23 through the atomizing tube 12, and then the nozzle 23 sprays it out at high pressure. The liquid medicine sprayed out at high pressure impacts the leak-proof plate 25, and pushes the leak-proof plate 25 to move, causing the leak-proof plate 25 and the fixed block 24 to separate from each other, and the liquid medicine enters the uniform mechanism 26 along the gap between the leak-proof plate 25 and the fixed block 24. The uniform mechanism 26 can make the sprayed liquid medicine more uniform and the atomization effect better. After the nozzle 23 has finished spraying the liquid medicine, the tension of the elastic member 241 is used to pull the leak-proof plate 25 and the fixed block 24 to form a closed state, which can effectively prevent the liquid medicine from dripping, and further improve the use effect of the atomizing head 121.

[0069] In addition, there are uncontrollable factors during the operation of the drive motor 7. When the drive shaft 71 stalls, the drive shaft 71 is used to drive the fixed ring 13 to rotate rapidly. Due to the centrifugal force when the fixed ring 13 rotates, the centrifugal part 132 pulls the centrifugal spring 131 to move. As the centrifugal part 132 moves outward and contacts the control switch 14, the control switch 14 is started and the electrical energy is transmitted to the electromagnet 16. At this time, the electromagnet 16 is energized to generate magnetism, and uses the magnetism to generate suction on the iron sleeve 15, thereby limiting its speed and stopping it from running, thereby avoiding damage to the oral cavity of the elderly patient when the drive shaft 71 stalls, and further improving the safety performance of the equipment.
