The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
 See Figure 1 to Figure 12 As shown, a safety care device for elderly patients with ear, nose and throat includes a housing 1, an exhalation tube 2 is fixedly connected to the upper part of the housing 1, and an inhalation tube 3 is fixedly connected to the surface of the exhalation tube 2, and the housing The inner part of 1 is movably connected with a shaking box 4, and the shell 1 and the shaking box 4 are movably connected by a compression spring 20. When the sonic rod 6 works, it will produce vibration, namely ultrasonic vibration, which is a sound wave with a frequency higher than 20000 Hz. , It has good directionality, strong penetrating ability, easy to obtain concentrated sound energy, and has a long transmission distance in water. This vibration can be used to atomize the liquid medicine, and due to the existence of the compression spring 20, the shaking box 4 can shake , To prevent the internal medicine from depositing and losing its efficacy.
 The inside of the housing 1 and located at the bottom of the shaking box 4 is fixedly connected with a liquid storage tank 5, the inside of the shaking box 4 is fixedly connected with a sonic rod 6, and the surface of the sonic rod 6 is movably connected with a mist pipe 7, and the mist pipe 7 is far away A threaded tube 8 is movably connected to one end of the sonic rod 6, and an adjusting shaft 21 is movably connected to the connection between the mist pipe 7 and the threaded tube 8. The amount of liquid medicine entering the mist pipe 7 can be adjusted by rotating the adjusting shaft 21. The threaded pipe 8 A negative pressure film 9 is movably connected to the end far away from the mist tube 7. The movement of the threaded tube 8 will drive the mist tube 7 away from the surface of the sonic rod 6. The surface of the negative pressure film 9 is fixedly connected with a tooth plate 10, and the surface of the tooth plate 10 is movable A gear 11 is connected. The inner side wall of the gear 11 is fixedly connected with a crescent socket 14. The crescent socket 14 is of a segmented design. When the spring rod 12 is driven by the force generated by exhalation, the flexible tube 15 is squeezed, Sliding against the curved surface of the crescent socket 14, when the spring rod 12 is driven by the force generated by inhalation, that is, the flexible tube 15 is stretched, and will slide against the curved surface of the crescent socket 14. The engagement between the two will drive the gear 11 on the tooth plate The surface of 10 slides, and when the gear 11 slides, the negative pressure film 9 is stretched and opened, and the wetting liquid originally present in the flexible tube will flow back into the liquid storage tank 5.
 The inner part of the gear 11 is movably connected with a spring rod 12, and the surface of the spring rod 12 is fixedly connected with a flexible tube 15, which connects the exhalation tube 2 with the flexible tube 15 in the housing 1. The flexible tube 15 is deformed by the gas blowing. Bending downwards, the gas flows to the inside of the spring rod 12. The bent flexible tube 15 drives the spring rod 12 to move on the surface of the crescent socket 14. The bottom of the flexible tube 15 is movably connected with a suction tube 18, and the inside of the suction tube 18 is fixedly connected with a diameter A small pipe is convenient for the wetting fluid to be sucked into the flexible pipe 15. The suction pipe 18 is fixedly connected with a suction plate 19 at one end away from the flexible pipe 15. The flexible pipe 15 has elastic deformation force and is easily affected by external forces.
 The upper part of the flexible tube 15 is fixedly connected with a connecting belt 16. The connecting belt 16 plays a role in absorbing excess wetting fluid, preventing the patient from inhaling too much wetting fluid and coughing. The connecting belt 16 is provided with an airflow channel 17 to follow the suction of the patient The liquid medicine is sucked into the patient's nasal cavity through the airflow channel 17. A suction bag 13 is movably connected to the inside of the spring rod 12. The suction bag 13 is squeezed to generate gas, and the gas is sucked into the liquid storage tank 5 through the suction plate 19 Moisturizing liquid, and keep the moisturizing liquid inside the suction tube 18; the patient still has a reaction that cannot suppress coughing, and if the human body wants to shake the mouth strongly when coughing, it must inhale deeply before coughing .
 The working principle and process of the present invention:
 In use, when the patient breathes normally, the exhaled air enters the flexible tube 15 through the expiratory tube 2, and the spring rod 12 moves while squeezing the suction bag 13. When the patient inhales normally, the force is small, which can Inhale gas from the inhalation tube 3, after the patient has breathed several times, the moisturizing liquid inside the liquid storage tank 5 will be sucked into the flexible tube 15. When the patient is dry to the mouth, the mood fluctuates and will exert subconscious force Breathing, if the inspiratory force is too large, the moisturizing fluid in the exhalation tube 2 will be sucked into the nasal cavity, and this moisturizing fluid is less, because the nasal cavity of the human body is connected with the oral cavity, the moist air will flow through the oral cavity. The tonsils can intermittently inhale moist air when the elderly breathes normally, and alleviate dry mouth; the patient will indirectly inhale moist air through normal breathing, but due to bacterial infection, when the patient inhales deeply , The inhalation tube 3 alone cannot provide the amount of inhaled air, so the air will be inhaled through the exhalation tube 2. At this time, the spring rod 12 will be pulled by the force and will be clamped in the direction of the crescent socket 14 and the negative pressure film 9 will be stretched at the same time. The sonic rod 6 loses pressure and starts to work, atomizing the liquid medicine inside the shaking box 4, and the liquid medicine inhaled into the patient's nasal cavity is partially attached to the inside of the nasal cavity, which plays the role of atomizing and inhaling medicine in small quantities according to the needs of the elderly; When the patient coughs, a small amount of liquid medicine is sprayed out, and when the patient coughs and sprays the liquid medicine, the liquid medicine will flow to the surface of the tonsils. The cool liquid medicine can relieve the discomfort of the patient's tonsils and reduce the frequency of coughing. .
 The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Anyone familiar with the technical field within the technical scope disclosed in the present invention, according to the technical solutions of the present invention and its Equivalent replacements or changes to the inventive concept should all fall within the protection scope of the present invention.
