Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a compressed air atomizer with adjustable fog volume. Background Art

[0002] In the medical field, atomization therapy is a common and effective treatment method. By converting drugs into tiny particles, it can directly act on the respiratory tract, thereby improving the treatment effect and reducing systemic side effects. Traditional compressed air atomizers are widely used in clinical applications and home care. However, they have many limitations.

[0003] Most of the existing conventional compressed air atomizers are designed with fixed parameters and cannot flexibly adjust atomization parameters according to factors such as the specific condition, age, and respiratory tract condition of the patient. For example, for children or patients with more sensitive respiratory tracts, too high atomization particle concentration or too large gas flow may cause discomfort reactions such as choking cough, affecting the treatment experience and effect; while for patients with severe conditions who require high-dose drug atomization, ordinary atomizers are difficult to provide sufficient drug output. In addition, the optimal atomization particle sizes required for different drugs vary, and fixed-parameter atomizers are difficult to adapt to the characteristics of various drugs, limiting their application in diverse treatment scenarios.

[[ID=�2]]Specific implementation manner

[0037] Refer to Figures 1-12, the present invention provides a compression air atomizer with adjustable atomization amount, which includes an atomizer main body 1 and a protective cover 2. An upward-opening liquid storage cavity 3 is provided on the atomizer main body 1, and an atomization generator 4 is installed in the liquid storage cavity 3. The atomization generator 4 includes a compressed air pump, a conical tube, a conical cover, a baffle, etc. The conical tube and the conical cover form a conical channel. The bottom opening of the conical channel is located at the bottom of the liquid storage cavity 3 and is immersed in the liquid medicine. The compressed air pump outputs high-speed air flow through the middle of the conical channel. When the air flow passes through the top opening of the conical channel, a negative pressure is formed. The liquid medicine in the conical channel is sucked out and impacts on the baffle to form atomized gas. This is the prior art. The protective cover 2 can block the top opening of the liquid storage cavity 3. An air outlet pipe 5 communicating with the liquid storage cavity 3 is installed on the protective cover 2. During use, an external pipe can be inserted into the air outlet pipe 5 to facilitate the patient to inhale the atomized gas for treatment.

[0038] As Figure 3 , Figure 4 and Figure 12 shown in, a communication filter groove is provided on the protective cover 2, and a control board 6 is installed in the filter groove. A plurality of conical grooves 7 are provided on the bottom surface of the control board 6. The top inner wall of the conical groove 7 is convex downward. An air outlet hole communicating with the conical groove 7 is provided on the top surface of the control board 6. The air inlet of the air outlet hole is located at the center of the convex on the top inner wall of the conical groove 7. A frustum block 8 is installed in the conical groove 7. An annular channel is formed between the outer periphery of the frustum block 8 and the inner wall of the conical groove 7. The frustum block 8 can move up and down in the conical groove 7. When the frustum block 8 moves up and down in the conical groove 7, the gap between the outer periphery of the frustum block 8 and the inner wall of the conical groove 7 changes. A groove 10 is provided at the top end of the frustum block 8; when the atomized gas reaches the top inner wall of the conical groove 7 through the annular channel, the atomized gas flows downward along the convex surface of the top inner wall of the conical groove 7 and moves to the groove 10 for collision and mixing (the flow direction of the atomized gas is shown by the arrow direction in Figure 12 ). In specific operation, the frustum block 8 moves up and down in the conical groove 7, thereby changing the gap size of the annular channel and the passing amount of the atomized gas, so as to control the atomization amount inhaled by the patient per unit time. After the liquid medicine is atomized in the liquid storage cavity 3, its distribution cannot be kept uniform. The atomized gas moves upward through the conical channel, converges and accumulates at the top position of the frustum block 8 and then is discharged through the air outlet hole, so that the atomized gas is mixed, which can make the drug distribution more uniform and make the atomized air flow more stable.

[0039] As Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 12As shown in the figure, a lifting frame 11 is installed inside the protective cover 2. The lifting frame 11 is slidably installed in the filtering tank and cannot rotate in the filtering tank. The lifting frame 11 can only move up and down in the filtering tank (vertical grooves that are slidably matched with the ends of the lifting frame 11 are provided on the inner wall of the filtering tank). A connecting block 12 is installed on the lifting frame 11. The diameter of the connecting block 12 is smaller than the diameter of the frustum block 8 to reduce the shielding of the bottom opening of the conical groove 7 by the lifting frame 11. The number of the connecting blocks 12 is the same as that of the frustum blocks 8 and they are arranged in one-to-one correspondence. The frustum block 8 is installed at one end of the connecting block 12 away from the lifting frame 11. A driving mechanism is also installed on the protective cover 2. The driving mechanism is used to drive the lifting frame 11 to slide up and down in the filtering tank. During specific operation, the driving mechanism works to drive the lifting frame 11 to move up and down. When the lifting frame 11 moves up and down, it will drive the connecting block 12 and the frustum block 8 to move up and down synchronously. When the frustum block 8 moves up and down, the gap between the outer circumference of the frustum block 8 and the inner wall of the conical groove 7 will also change accordingly, thereby changing the cross-sectional area of the annular channel and adjusting the passing amount of the atomized gas per unit time, which is convenient for adapting to different patients.

[0040] As Figure 1 , Figure 2 and Figure 3 As shown in the figure, the driving mechanism includes a connecting rod 13 and a rotating cap 14; the connecting rod 13 threadedly penetrates through the control board 6, the bottom end of the connecting rod 13 is rotatably connected to the lifting frame 11, the rotating cap 14 is installed on the top of the protective cover 2, and the rotating cap 14 can drive the connecting rod 13 to rotate. When adjusting the lifting of the frustum block 8, by rotating the rotating cap 14, the rotating cap 14 drives the connecting rod 13 to rotate. Since the connecting rod 13 and the control board 6 are in threaded cooperation, the threaded section of the connecting rod 13 and the control board 6 are in threaded cooperation, the bottom end of the connecting rod 13 moves up and down, and the bottom end of the connecting rod 13 drives the lifting frame 11 and the frustum block 8 to move up and down, thereby controlling the size of the annular channel and the flow rate of the atomized gas.

[0041] As Figure 6 As shown in the figure, a plurality of conical grooves 7 are arranged in an annular array with different inner diameters in multiple rings. As the radius of the annular array increases, the inner diameter of the conical grooves 7 in the corresponding annular array also increases, and the caliber of the air outlet holes corresponding to the conical grooves 7 also increases. In actual situations, the inner diameters of the plurality of conical grooves 7 gradually increase from the inner circle to the outer circle. A fog amount adjusting mechanism is installed on the control board 6. The fog amount adjusting mechanism is used to adjust the atomized gas passing through the air outlet holes per unit time. In addition to adjusting the passing amount of the atomized gas per unit time in the annular channel through the lifting movement of the frustum block 8 in the above content, the atomized gas passing through the air outlet holes per unit time can also be controlled by the adjusting mechanism, further controlling the passing amount of the atomized gas per unit time, which is convenient for patients to adjust and use, making the effect of atomization treatment better.

[0042] As Figure 2, Figure 3 , Figure 8 and Figure 10 As shown in Figure 3 , Figure 8 and Figure 10 , the adjusting mechanism includes an adjusting plate 15 and a rotating assembly; the adjusting plate 15 is rotatably mounted on the top surface of the control plate 6. A plurality of communication holes are formed through the adjusting plate 15. The plurality of communication holes are arranged in one-to-one correspondence with the plurality of air outlet holes. The diameters of the plurality of communication holes gradually increase from the center of the adjusting plate 15 to the outer circle direction of the adjusting plate 15. The plurality of communication holes are divided into a plurality of annular arrays with different radii. As the radius of the annular array increases, the diameter of the communication hole also increases. Only one communication hole in one annular array and one air outlet hole in one annular array coincide among the communication holes of the plurality of annular arrays and the air outlet holes of the plurality of annular arrays. The distribution of the communication holes is as shown in Figure 8 As shown in Figure 8 , by rotating the adjusting plate 15, the communication hole and the air outlet hole gradually coincide. Assuming that in the initial state, the innermost communication hole and the innermost air outlet hole are communicated, then the other air outlet holes are covered and blocked by the adjusting plate 15. The atomized gas can only pass through the innermost air outlet hole. At this time, the passing amount of the atomized gas is the smallest (the cross-section of the annular channel formed by the conical groove 7 and the frustum block 8 remains unchanged). When the outermost communication hole and the outermost air outlet hole are communicated, the other air outlet holes are covered by the adjusting plate 15. At this time, the passing amount of the atomized gas is the largest (the cross-section of the annular channel formed by the conical groove 7 and the frustum block 8 remains unchanged).

[0043] As Figure 2 , Figure 3 and Figure 5As shown in the figure, the rotating assembly includes a metal rod 16 and a first gear block 17; an activity groove 18 is formed in the adjusting plate 15. One end of the metal rod 16 penetrates through the adjusting plate 15 and extends into the activity groove 18. The first gear block 17 is fixedly connected to the bottom end of the metal rod 16. The inner wall of the lower section of the activity groove 18 is provided with first teeth. When the first gear block 17 descends in the activity groove 18, the first gear block 17 can engage with the first teeth. The top end of the metal rod 16 is detachably connected to the rotating cap 14. A downward movement groove is also formed at the top of the protective cover 2. The rotating cap 14 can move downward in the downward movement groove. During actual operation, when rotating the adjusting plate 15, pinch the vertical bar at the top of the rotating cap 14 and press it down, so that the rotating cap 14, the metal rod 16 and the first gear block 17 descend synchronously. When the first gear block 17 descends to the position of the first teeth, the first teeth are stuck in the tooth grooves of the first gear block 17. At this time, rotate the rotating cap 14, and the rotating cap 14 drives the metal rod 16, the first gear block 17 and the adjusting plate 15 to rotate synchronously. By rotating to adjust the coincidence and connection of the corresponding communication holes and air outlet holes, the size of the fog output can be adjusted (in actual situations, a telescopic hole is formed on the outer periphery of the metal rod 16. A spherical ball and a spring are arranged in the telescopic hole. The spring can push the spherical ball to move out of the telescopic hole. A plurality of vertical positioning grooves adapted to the spherical ball are formed on the inner wall of the protective cover 2. The spherical ball can partially enter the vertical positioning grooves. When rotating the metal rod 16, the spherical ball can break away from the vertical positioning grooves, but there will be a sense of damping. The user judges whether the rotation adjustment is in place through the impact sound when the spherical ball enters the vertical positioning grooves and the sense of damping when the spherical ball continues to rotate after entering the vertical positioning grooves. This is not shown in the figure).

[0044] As Figure 3 and Figure 5As shown in [figures], a second gear block 19 is fixedly connected to the top end of the connecting rod 13. A variable connection groove 20 is formed in the metal rod 16. The top end of the connecting rod 13 penetrates through the adjusting plate 15 and the metal rod 16 and extends into the variable connection groove 20. The second gear block 19 slides in the variable connection groove 20. The upper half of the variable connection groove 20 is an idle stroke section. When the second gear block 19 reaches the idle stroke section, the second gear block 19 can rotate within the idle stroke section. A jacking spring 21 is arranged in the variable connection groove 20. The two ends of the jacking spring 21 respectively abut against the top surface of the second gear block 19 and the top inner wall of the variable connection groove 20. In actual situations, when the rotary cap 14 needs to adjust the lifting of the frustum block 8, it also needs to control the lifting of the adjusting plate 15. In order to achieve a more precise adjustment effect, it is necessary for the rotary cap 14 to be able to independently control the operation of the frustum block 8 and the adjusting plate 15 when rotating. When the rotary cap 14 needs to adjust the lifting of the frustum block 8, it is necessary to ensure that the adjusting plate 15 does not rotate following the rotation of the rotary cap 14. At this time, the rebounding effect of the jacking spring 21 jacks up the metal rod 16. When the metal rod 16 rises, it drives the first gear block 17 to rise synchronously. The first gear block 17 disengages from the first gear. The first gear block 17 can rotate within the upper half of the movable groove 18. Since the metal rod 16 rises, the second gear block 19 is located in the lower half of the variable connection groove 20. At this time, the second gear block 19 cannot rotate within the variable connection groove 20. Therefore, when rotating the rotary cap 14, the rotary cap 14 drives the metal rod 16, the second gear block 19, and the connecting rod 13 to rotate synchronously. The end of the connecting rod 13 drives the lifting frame 11 and the frustum block 8 to perform a lifting motion. When it is necessary to adjust the rotation of the adjusting plate 15, first rotate the rotary cap 14 so that the spherical ball is caught in one of the vertical positioning grooves, and then press down the rotary cap 14. The rotary cap 14 drives the metal rod 16 and the first gear block 17 to descend synchronously. At this time, the jacking spring 21 is compressed. The second gear block 19 rises from the lower half of the variable connection groove 20 to the idle stroke section in the upper half. The second gear block 19 can rotate within the idle stroke section of the variable connection groove 20 (the principle is the same as the working principle of the first gear block 17 in the movable groove 18). The second gear block 19 reaches the lower half of the movable groove 18 and meshes with the first gear. Rotating the rotary cap 14 drives the metal rod 16, the first gear block 17, and the adjusting plate 15 to rotate until the impact sound of the spherical ball entering another vertical positioning groove or the damping feeling after the spherical ball enters the vertical positioning groove is heard, then it can be known that an adjustment is completed. Adjust to the appropriate fog output according to the above operations. The operation is simple and convenient (the lower half of the variable connection groove 20 needs to maintain a certain length. When adjusting the lifting of the lifting frame 11, the second gear block 19 needs to rise and fall within the lower half of the variable connection groove 20).

[0045] As Figure 2 , Figure 3 and Figure 10As shown in the figure, a vertical pipe 22 is fixedly installed on the top surface of the adjusting plate 15. The number of the vertical pipes 22 is the same as and corresponds one by one to the number of the communication holes, and the inner diameter of the vertical pipe 22 is the same as the diameter of the corresponding communication port. In actual situations, the atomized drug gas may also re-converge and liquefy. Therefore, after the atomized gas liquefies in the protective cover 2, it can accumulate on the adjusting plate 15. Blocked by the vertical pipe 22, it prevents the liquefied liquid medicine from flowing back and blocking the air outlet hole, ensuring smooth fog output.

[0046] As Figure 2 , Figure 3 , Figure 4 and Figure 11 As shown in the figure, a plurality of storage grooves are formed in the inner wall of the conical groove 7. A partition piece 23 is slidably installed in the storage groove. A pressing spring 9 is also installed in the storage groove. Two ends of the pressing spring 9 are respectively connected to one side of the partition piece 23 and the inner wall of the storage groove. The pressing spring 9 can drive the other side of the partition piece 23 to abut against the outer circumference of the frustum-shaped block 8. Driven by the rebounding action of the pressing spring 9, the partition piece 23 abuts against the outer circumference of the frustum-shaped block 8, and the annular channel formed by the frustum-shaped block 8 and the conical groove 7 is divided into a plurality of channels. The partition structure in the channel can divide and disturb the atomized liquid medicine gas, prompting the gas and liquid medicine particles to collide and mix with each other, improving the mixing uniformity, making the drug dispersion more ideal, and being conducive to improving the treatment effect.

[0047] As mentioned above, the above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
