An annular seat is movably connected to the side of the connecting frame away from the air blowing pipe. Multiple fixing rods are fixedly connected to the bottom end of the annular seat. Multiple slots are fixedly formed at the bottom end of the connecting frame, and movable rods are movably connected inside each slot. Movable plates are fixedly connected to the outer sides of the rods. The outer sides of the fixed rods and the inner sides of the movable plates are movably connected. The end of the movable plate near the rotating rod is fixedly connected to the bottom end of the arc-shaped fixed seat. The bottom ends of the multiple movable rods are movably connected to a ring frame. The top of the ring frame is fixedly connected to multiple connectors.

A push button is movably connected inside the arc-shaped groove. One end of the push button is fixedly connected to the outer side of the ring seat.

[0009] In a preferred embodiment, a placement frame is fixedly connected to the side of the control unit near the air blowing pipe, and a support column is fixedly connected to the bottom of the control unit. A base is fixedly connected to the bottom of the support column, and a rotating seat is movably connected to the bottom of the base. Multiple movable seats are fixedly connected to the bottom of each rotating seat, and movable wheels are movably connected to the inner side of each movable seat. A filter plate is fixedly connected to the top of the extension pipe.

[0010] In a preferred embodiment, the extension assembly further includes a slide plate, the outer side of which is fixedly connected to the inner side of the air blowing pipe. A sliding seat is fixedly connected to the outer side of the extension pipe, and the sliding seat is movably connected to the slide plate.

[0011] A method of using an auxiliary sputum expectoration air blowing device, comprising the following steps:

[0012] Step 1: When the patient needs assisted expectoration, place the air tube in the mouth and blow air into the air tube. At this time, the impeller in the air tube will start to rotate under the action of airflow. Due to the rotation of the impeller, gas pressure will be generated. This pressure can cause the patient's lung cavity and cilia to vibrate, thereby ensuring the flow of gas in the lung cavity and creating conditions for loosening the sputum.

[0013] Step 2: Manually operate the arc-shaped fixing seat, moving it away from or closer to the rotating rod. By changing the distance between the arc-shaped fixing seat and the rotating rod, the holding force on the rotating rod can be adjusted. Since the change in holding force affects the resistance encountered when the impeller rotates, the impeller speed can be adjusted. Different impeller speeds will generate airflows of different intensities, which in turn will produce different degrees of vibration in the patient's lung cavity, so as to more effectively loosen the sputum.

[0014] Step 3: Adjust the extension tube according to the patient's height. Since the outer side of the extension tube is movably connected to the inner side of the top of the blowing tube, the extension tube can be stretched or contracted to change its length, making the whole device more suitable for the patient's use and ensuring that the patient can comfortably use the blowing tube to perform the blowing operation during the assisted sputum expectoration process.

[0015] As can be seen from the above, the sputum-clearing blowing device provided by the present invention has the effect of adjusting the impeller speed and precisely adjusting the airflow vibration intensity according to the patient's sputum viscosity, lung cavity condition, etc., to meet the personalized needs of different patients.

[0025] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] The sputum-clearing inhalation device disclosed in this invention is mainly used in scenarios where the structure is relatively complex and it is difficult to adapt to the usage requirements of patients with different lung capacities, thus limiting its applicability.

[0027] Reference Figure 1-8 An auxiliary sputum expectoration blowing device includes a control unit 1, a control panel 2 fixedly connected to the top of the control unit 1, a control button 3 fixedly connected to the top of the control unit 1, a connecting wire 7 fixedly connected to the front end of the control unit 1, a blowing tube 8 fixedly connected to the top end of the connecting wire 7, an airflow control component 14 disposed inside the blowing tube 8, and an extension component 12 disposed at the top end of the blowing tube 8.

[0028] The airflow control assembly 14 includes an impeller 1404, a rotating rod 1403 is fixedly connected to the inner side of the impeller 1404, and the impeller 1404 is located inside the air blowing pipe 8. Multiple arc-shaped fixing seats 1415 are provided on the outer side of the bottom end of the rotating rod 1403.

[0029] The extension assembly 12 includes an extension tube 1203, which is movably connected to the outer side of the air blowing tube 8 and the inner side of the top end of the air blowing tube 8, and the extension tube 1203 is located above the impeller 1404.

[0030] Reference Figure 4 , Figure 5 and Figure 6 The airflow control assembly 14 also includes an annular groove 1401, the outer side of which is fixedly connected to the inner side of the air blowing pipe 8. A sliding frame 1402 is movably connected to the side of the annular groove 1401 away from the air blowing pipe 8. The inner side of the sliding frame 1402 is fixedly connected to the outer side of the rotating rod 1403. A connecting frame 1405 is provided below the impeller 1404. A circular groove is provided on the outer side of the air blowing pipe 8. The inner side of the circular groove is fixedly connected to both ends of the outer side of the connecting frame 1405. An annular seat 1407 is movably connected to the side of the connecting frame 1405 away from the air blowing pipe 8. Multiple fixing rods 1408 are fixedly connected to the bottom end of the annular seat 1407. Multiple slots are fixedly provided at the bottom end of the connecting frame 1405. Movable rods 1409 are movably connected inside each slot, and movable plates are fixedly connected to the outer side of each movable rod 1409. 1410, the outer side of the fixed rod 1408 and the inner side of the movable plate 1410 are movably connected. The end of the movable plate 1410 near the rotating rod 1403 is fixedly connected to the bottom end of the arc-shaped fixed seat 1415. The bottom ends of multiple movable rods 1409 are movably connected to a ring frame 1411. The top of the ring frame 1411 is fixedly connected to multiple connectors 1412. The front end of each connector 1412 is fixedly connected to a tension spring 1413. The end of the tension spring 1413 away from the connector 1412 is fixedly connected to a connecting plate 1414. One end of the connecting plate 1414 is fixedly connected to the outer side of the ring seat 1407. An arc-shaped groove is opened on the outer side of the connecting frame 1405. A push button 1406 is movably connected inside the arc-shaped groove. One end of the push button 1406 is fixedly connected to the outer side of the ring seat 1407.

[0031] Specifically, when a patient performs assisted expectoration ventilation, the patient blows air into the ventilation tube 8. The airflow enters the ventilation tube 8, driving the impeller 1404 to rotate. The rotating rod 1403 rotates synchronously with the impeller 1404. Simultaneously, the rotation of the impeller 1404 generates gas pressure, causing vibration of the patient's lung cavity and cilia, maintaining gas flow. Manually pushing the push button 1406 causes the annular seat 1407 to move within the arc-shaped groove on the outside of the connecting frame 1405. When the annular seat 1407 moves, the bottom fixing rod 1408 moves accordingly. Through its movable connection with the movable plate 1410, it pushes the movable rod 1409 to move within the bottom slot of the connecting frame 1405. The movable plate 1410, driven by the fixing rod 1408, moves the arc-shaped fixing seat 1415 connected to it closer to or away from the rotating rod 1403. When the arc-shaped fixing seat 1415 moves closer to or away from the rotating rod 1403... When the rotating rod 1403 is rotated, the holding force on the rotating rod 1403 increases, the rotational resistance increases, and the speed of the impeller 1404 decreases. When the arc-shaped fixed seat 1415 moves away from the rotating rod 1403, the holding force decreases, and the speed of the impeller 1404 increases. By adjusting the speed, airflow vibrations of different intensities are formed, which loosen the sputum. The auxiliary structures such as the tension spring 1413 and the connecting piece 1412 adapt to the displacement of the movable rod 1409 and the movable plate 1410 when the push button 1406 pushes the ring seat 1407 to move. Through stretching or compression deformation, the transmission is ensured to be smooth and the process of adjusting the holding force of the arc-shaped fixed seat 1415 on the rotating rod 1403 is smooth and without jamming. During the process, adjusting the speed of the impeller 1404 can precisely adjust the intensity of airflow vibration according to the viscosity of the patient's sputum and the condition of the lung cavity, so as to meet the personalized needs of different patients.

[0032] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8 A placement rack 4 is fixedly connected to the side of the control unit 1 near the air blowing pipe 8, and a support column 5 is fixedly connected to the bottom of the control unit 1. A base 6 is fixedly connected to the bottom of the support column 5. A rotating seat 9 is movably connected to the bottom of the base 6. Multiple movable seats 10 are fixedly connected to the bottom of each rotating seat 9. Movable wheels 11 are movably connected to the inner side of each movable seat 10. A filter plate 13 is fixedly connected to the top of the extension pipe 1203.

[0033] Reference Figure 1 , Figure 2 and Figure 3The extension assembly 12 also includes a slide plate 1201, the outer side of which is fixedly connected to the inner side of the air blowing pipe 8. A sliding seat 1202 is fixedly connected to the outer side of the extension pipe 1203, and the sliding seat 1202 is movably connected to the slide plate 1201. A limiting plate 1204 is fixedly connected to the outer side of the extension pipe 1203. A circular frame 1205 is fixedly connected to the outer side of the top end of the air blowing pipe 8. A fixing frame 1206 is fixedly connected to the side of the circular frame 1205 near the limiting plate 1204. Symmetrical push seats 1207 are movably connected to the inner side of the fixing frame 1206. A pusher 1210 is fixedly connected to one side of the pusher seat 1207. A bidirectional telescopic rod 1208 is fixedly connected to the opposite side of the pusher seat 1207. A compression spring 1209 is provided on the outer side of the bidirectional telescopic rod 1208. Both ends of the compression spring 1209 are fixedly connected to the opposite side of the pusher seat 1207. A limit frame 1211 is fixedly connected to the bottom end of the pusher seat 1207. A rectangular hole is opened at the top end of the air blowing pipe 8. The limit frame 1211 is movably connected inside the rectangular hole. Multiple slots are provided on the limit plate 1204. The limit frame 1211 is movably connected inside the slots.

[0034] Specifically, when adjusting the extension tube 1203 according to the patient's height, manually pressing the pusher 1210 causes the pusher seat 1207 to move to both sides along the inner side of the fixed frame 1206. The compression spring 1209 is deformed by compression, and the bidirectional telescopic rod 1208 extends, causing the limit frame 1211 to exit from the slot of the limit plate 1204, thus releasing the lock on the extension tube 1203. Since the sliding seat 1202 is movably connected to the sliding plate 1201, the extension tube 1203 can be manually pulled up and down. When the extension tube 1203 moves, the limit plate 1204 moves synchronously. The slot passes through the rectangular hole at the top of the air tube 8 in sequence, realizing the adjustment of the length of the extension tube 1203 to suit the patient's height. Releasing the pusher 1210 releases the elastic potential energy of the compression spring 1209, pushing the pusher seat 1207 to reset, and the limit frame 1211 is reinserted into the slot of the corresponding height. In this process, the needs of patients of different heights are met, improving the adaptability of use.

[0035] A method of using an auxiliary sputum expectoration air blowing device, comprising the following steps:

[0036] Step 1: When the patient needs assisted expectoration, place the air tube 8 in the mouth and blow air into the air tube 8. At this time, the impeller 1404 inside the air tube 8 will start to rotate under the action of the airflow. As the impeller 1404 rotates, it will generate gas pressure. This pressure can cause the patient's lung cavity and cilia to vibrate, thereby ensuring the flow of gas in the lung cavity and creating conditions for loosening the sputum.

[0037] Step 2: Manually operate the arc-shaped fixing seat 1415 to move it away from or closer to the rotating rod 1403. By changing the distance between the arc-shaped fixing seat 1415 and the rotating rod 1403, the holding force on the rotating rod 1403 can be adjusted. Since the change in holding force will affect the resistance encountered by the impeller 1404 when it rotates, the speed of the impeller 1404 can be adjusted. Different impeller 1404 speeds will generate airflows of different intensities, which will in turn produce different degrees of vibration in the patient's lung cavity, so as to more effectively loosen the sputum.

[0038] Step 3: Adjust the extension tube 1203 according to the patient's height. Since the outer side of the extension tube 1203 is movably connected to the inner side of the top of the air tube 8, the extension length can be changed by stretching or contracting the extension tube 1203, making the whole device more suitable for the patient's use and ensuring that the patient can comfortably use the air tube 8 to perform the air blowing operation during the assisted sputum expectoration process.
