Description

Technical Field

[0001] The present invention belongs to the technical field of pediatric atomization, and particularly relates to a drug atomization device for pediatrics. Background Art

[0002] Currently, for drug atomization devices for pediatrics, an atomizing nozzle is usually used to atomize drugs. During use, the mixed drug needs to be poured into a piston tube, and then the piston is pushed, so that the drug in the piston tube is pushed by the piston and finally ejected from the atomizing nozzle to achieve drug atomization. This method requires pouring the liquid medicine and powder medicine into a medicine bottle, and then swinging the medicine bottle to mix the liquid medicine and powder medicine. However, due to the surface tension of the liquid medicine, when the liquid medicine and powder medicine come into contact, a clustering phenomenon will occur. Doctors mix the liquid medicine and powder medicine by manually swinging the medicine bottle, which is difficult to make the two fully blend, resulting in the presence of clustered powder medicine in the final liquid medicine, affecting the atomization effect.

[0003] Therefore, a drug atomization device for pediatrics is needed to solve the problem that when the liquid medicine and powder medicine come into contact in the prior art, a clustering phenomenon occurs, affecting the atomization effect. Summary of the Invention

[0015] Compared with the prior art, a pediatric drug atomization device provided by the present invention has at least the following beneficial effects: (1) By setting the servo motor, the fourth gear, the L-shaped rack, the third rack, the third piston tube and the third piston, the first rack can rotate forward and backward, and then drive the rotating rod to rotate forward and backward. By setting the swing rod, the knocking ball and the tuning fork, the tuning fork can vibrate at a high frequency, generating eddies and convection in the liquid medicine, accelerating the flow of the liquid medicine, quickly dispersing the powder medicine into each area of the liquid medicine, realizing the uniform distribution of the powder medicine in the liquid medicine. At the same time, the tuning fork can, through high-frequency vibration, break the surface tension of the liquid medicine, prompting the liquid medicine to penetrate into the gaps of the powder medicine, avoiding the phenomenon of agglomeration when the liquid medicine contacts the powder medicine, resulting in uneven mixing of the liquid medicine and the powder medicine, and thus affecting the atomization effect.

[0017] (3) By setting the elastic strip and the card interface, when the push column moves, the elastic strip can bend during movement and then be clamped with the card interfaces at different positions. This setting makes the distance that the first piston moves each time the same, and thus can realize multiple uniform discharges of the mixed liquid medicine, without excessive discharge at one time. At the same time, multiple discharges can make the liquid medicine more fully blend into the child's oral cavity, and the treatment effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Please refer to Figures 1-13 , the present invention provides a pediatric drug atomization device, including a mixing tube 100. A plurality of uniformly distributed tuning forks 300 are fixed to the top of the inner side wall of the mixing tube 100. A plurality of uniformly distributed rotating rods 200 are movably connected to the bottom of the inner side wall of the mixing tube 100. A swing rod 201 is fixed to the top of the outer side wall of the rotating rod 200. A knocking ball 202 is fixed to one end of the swing rod 201. A plurality of stirring bars 203 distributed in a circular pattern are fixed to the bottom of the outer side wall of the rotating rod 200. Two positioning columns 306 are fixed between the opposite side surfaces of the inner side wall of the mixing tube 100. A connecting plate 302 is movably connected between the two positioning columns 306. Four springs 301 are fixed to one side surface of the connecting plate 302. One end of the spring 301 is fixed to one side surface of the inner side wall of the mixing tube 100.

[0024] As a further aspect of the present invention, a second piston tube 400 is connected through the side of the outer side wall of the mixing tube 100. One end of the second piston tube 400 close to the spring 301 extends into the mixing tube 100. A second piston 401 is movably connected in the second piston tube 400. A first fixing plate 402 is fixed to one side surface of the second piston 401. A moving rod 304 is fixed to one side surface of the first fixing plate 402. A second rack 403 is fixed to the other side surface of the second piston 401. The second rack 403 passes through one end of the second piston tube 400.

[0025] Through the provided second piston 401, the liquid medicine inside the mixing tube 100 will not enter the space between the second rack 403 and the second piston 401, avoiding the situation where the liquid medicine flows out from the second piston tube 400. At the same time, this setting enables the second rack 403 and the moving rod 304 to form a connection. Thus, when the second rack 403 moves, it can push the moving rod 304 to move, effectively ensuring that the transmission of the second rack 403 is transmitted to the moving rod 304.

[0026] As a further aspect of the present invention, a blocking bar 305 is fixed on the top surface of the moving rod 304 near one side of the connecting plate 302. A connecting rod 303 is fixed on the connecting plate 302 near the moving rod 304. The connecting rod 303 cooperates with the blocking bar 305.

[0027] Through the provided connecting rod 303 and blocking bar 305, when the moving rod 304 moves, it can drive the blocking bar 305 to move, and then drive the connecting rod 303 to move. With this setting, the transmission of the moving rod 304 can be transmitted to the connecting plate 302, effectively driving the connecting plate 302 to move.

[0028] As a further aspect of the present invention, a third piston tube 407 is connected through the outer side wall of the mixing tube 100. A third piston 408 is movably connected inside the third piston tube 407. A second fixing plate 409 is fixed on one side surface of the third piston 408. A first rack 205 is fixed on one side surface of the second fixing plate 409. A third rack 410 is fixed on the other side surface of the third piston 408. The third rack 410 passes through one end of the third piston tube 407. A first gear 204 is fixed in the middle of the outer side wall of the rotating rod 200. The first gear 204 meshes with the first rack 205.

[0029] Through the provided third piston 408, the liquid medicine inside the mixing tube 100 will not enter the space between the third rack 410 and the third piston 408, avoiding the liquid medicine in the mixing tube 100 from being discharged through the third piston tube 407. At the same time, it enables the transmission of the third rack 410 to be transmitted to the first rack 205 through the third piston 408. With this setting, it ensures that while avoiding the discharge of the liquid medicine outside the mixing tube 100, the rotation of a number of first gears 204 can be realized.

[0030] As a further aspect of the present invention, a housing 404 is fixed on one side of the outer side wall of the mixing tube 100. A second gear 405 is movably connected to the inner top of the housing 404. The second gear 405 meshes with the second rack 403. A third gear 406 is movably connected to the inner bottom of the housing 404. The third gear 406 meshes with the third rack 410.

[0031] Through the provided second gear 405 and third gear 406, a connection can be formed between the second rack 403 and the third rack 410. With this arrangement, when the third rack 410 moves, it can drive the second rack 403 to move through the transmission of the second gear 405 and the third gear 406.

[0032] As a further aspect of the present invention, a limiting rod 307 is fixed to the bottom of the inner side wall of the mixing tube 100, and the first rack 205 is movably connected to the limiting rod 307.

[0033] Through the provided limiting rod 307, the position of the first rack 205 can be movably limited. When the first rack 205 moves, the teeth of the first rack 205 will not be misaligned with the teeth of the first gear 204, thereby avoiding transmission blockage.

[0034] As a further aspect of the present invention, a sleeve 102 is provided below the mixing tube 100. A connecting frame 101 is fixed between the sleeve 102 and the mixing tube 100. On one side of the inner part of the sleeve 102, a first piston tube 103 is fixed. On one side of the outer side wall of the first piston tube 103, an atomizing nozzle 104 is fixed. A first piston 105 is movably connected inside the first piston tube 103. On the side of the first piston 105 away from the atomizing nozzle 104, a pushing column 106 is fixed. At the bottom of the side of the pushing column 106 away from the atomizing nozzle 104, a pushing rod 107 is fixed. On one side of the bottom of the inner side wall of the sleeve 102, a first opening 108 is provided. The pushing rod 107 passes through the first opening 108. A connecting pipe 600 is connected between the mixing tube 100 and the first piston tube 103. A valve 601 is provided at the top of the outer side wall of the connecting pipe 600.

[0035] Through the provided pushing column 106 and first piston 105, the liquid medicine inside the sleeve 102 can be pushed by the first piston 105 and then sprayed out through the atomizing nozzle 104 to achieve atomization of the liquid medicine. Through the provided connecting pipe 600, the mixing tube 100 and the first piston tube 103 can be connected, so that the mixed liquid medicine in the mixing tube 100 can enter the first piston tube 103 through the connecting pipe 600. Through the provided valve 601, the connecting pipe 600 can be blocked and opened, so as to facilitate controlling the liquid medicine in the mixing tube 100 to enter the first piston tube 103.

[0036] As a further solution of the present invention, side rods 700 are respectively fixed on both sides inside the sleeve 102. A number of uniformly distributed card interfaces 701 are respectively formed on one side of the two side rods 700 close to each other. A limit sleeve 702 is fixed on the outer side wall of the push column 106 away from the atomizing nozzle 104. The four corners inside the limit sleeve 702 are provided with rounded corners. An elastic strip 703 is fixed inside the limit sleeve 702. Both ends of the elastic strip 703 are respectively engaged with the corresponding card interfaces 701 on both sides.

[0037] Through the provided rounded corners, when the two sides of the elastic strip 703 are bent, they can bend along the rounded corner positions, avoiding the situation where the elastic strip 703 is bent when it contacts the corner position without rounded corners; through the provided elastic strip 703 and card interfaces 701, when the push column 106 moves, the elastic strip 703 can bend during the movement and then be engaged with the card interfaces 701 at different positions. With this setting, the distance that the first piston 105 moves each time is the same, and thus multiple uniform liquid discharges can be achieved.

[0038] As a further solution of the present invention, a mounting plate 500 is fixed on one side of the bottom of the outer side wall of the mixing tube 100. A servo motor 501 is fixed on one side surface of the mounting plate 500. A fourth gear 502 is fixed at the output end of the servo motor 501. An L-shaped rack 411 is fixed on one side of the bottom surface of the third rack 410. The L-shaped rack 411 is engaged with the fourth gear 502. An outer sleeve 413 is fixed on one side of the outer side wall of the mixing tube 100. A second opening 412 is formed at the bottom of the outer side wall of the outer sleeve 413. The L-shaped rack 411 passes through the second opening 412.

[0039] Through the provided servo motor 501 and fourth gear 502, the third rack 410 can move. Through the provided outer sleeve 413, the second rack 403 and the third rack 410 can be wrapped, avoiding the exposure of the second rack 403 and the third rack 410 outside.

[0040] As a further solution of the present invention, a medicine inlet tube 602 is connected through the top of one side of the outer side wall of the mixing tube 100. A plugging cap 603 is detachably connected to the top of the medicine inlet tube 602.

[0041] Through the provided medicine inlet tube 602, the liquid medicine can enter the mixing tube 100 from the medicine inlet tube 602. Through the provided plugging cap 603, the medicine inlet tube 602 can be plugged; the connection method between the plugging cap 603 and the medicine inlet tube 602 is a threaded connection.

[0042] Among them, the number of teeth and the spacing of the first rack 205, the first gear 204, the second rack 403, the second gear 405, the third gear 406, the third rack 410, the L-shaped rack 411 and the fourth gear 502 should be set according to the actual situation to ensure that when the knocking ball 202 knocks the tuning fork 300, the connecting plate 302 just moves to the side far from the outer shell 404 in the mixing tube 100; the surfaces of the spring 301, the tuning fork 300, the first rack 205 and the first gear 204 are all treated with a galvanizing process for anti-corrosion.

[0043] In summary: When mixing multiple different drugs, first rotate the plugging cap 603 to remove it, then pour the powdered drug and the required multiple liquid medicines into the mixing tube 100 in sequence until the liquid medicine level in the mixing tube 100 is close to the knocking ball 202 but does not contact the knocking ball 202. Then install the plugging cap 603, hold the entire device, start the servo motor 501. The rotation of the servo motor 501 drives the fourth gear 502 to rotate. The rotation of the fourth gear 502 drives the L-shaped rack 411 to move. The movement of the L-shaped rack 411 drives the third rack 410 to move. The movement of the third rack 410 drives the third piston 408 to move. The movement of the third piston 408 drives the first rack 205 to move. The movement of the first rack 205 drives several first gears 204 to rotate. The rotation of the first gears 204 drives the rotating rod 200 to rotate. The rotation of the rotating rod 200 drives the stirring bar 203 to rotate. The stirring bar 203 can stir and mix the liquid medicine on one side inside the mixing tube 100. At the same time, the rotation of the rotating rod 200 drives the swinging rod 201 to rotate, causing the knocking ball 202 to rotate and knock on the tuning fork 300. The tuning fork 300 vibrates, causing the liquid medicine in the middle of the mixing tube 100 to be vibrated and stirred. When the third rack 410 moves, it drives the third gear 406 to rotate. The rotation of the third gear 406 drives the second gear 405 to rotate. The rotation of the second gear 405 drives the second rack 403 to move. The movement of the second rack 403 drives the second piston 401 to move. The movement of the second piston 401 drives the moving rod 304 to move. The movement of the moving rod 304 causes the blocking bar 305 to push the connecting rod 303 to move. The movement of the connecting rod 303 drives the connecting plate 302 to move. During the movement of the connecting plate 302, the liquid medicine on the other side inside the mixing tube 100 can be stirred and mixed, and at the same time, the spring 301 is pulled. During the stretching of the spring 301, the spring 301 can stir the liquid medicine. When the knocking ball 202 knocks on the tuning fork 300, the connecting plate 302 just moves to the side inside the mixing tube 100 away from the outer shell 404. During this process, the liquid medicine at one side, the other side, and the middle position inside the mixing tube 100 are respectively stirred. After the knocking ball 202 knocks on the tuning fork 300, the servo motor 501 rotates in the reverse direction, causing the tuning fork 300 to rotate and return to the initial position, and the spring 301 and the connecting plate 302 return to the initial position. During this process, the stirring bar 203 rotates in the reverse direction to stir the liquid medicine, and the connecting plate 302 and the spring 301 stir the liquid medicine. After the servo motor 501 repeats the forward and reverse rotations several times, it is turned off. The forward and reverse rotations and the shutdown of the servo motor 501 during this process are controlled by an internal program.

[0044] After opening the valve 601, the uniformly mixed liquid medicine in the mixing tube 100 enters the first piston tube 103 through the connecting tube 600. At this time, there is air at the top inside the first piston tube 103. Tilt the whole device downward so that the liquid medicine fills the first piston tube 103. At this time, the air inside the first piston tube 103 is on one side of the first piston 105. Then push the push rod 107, causing the push column 106 to move. The movement of the push column 106 drives the elastic strip 703 to move, causing the elastic strip 703 to bend and move out of the clamping interface 701. After that, the elastic strip 703 moves to another clamping interface 701 and engages. During this process, the first piston 105 moves and pushes some of the air inside the first piston tube 103 until some of the air enters the connecting tube 600. Continue to push the push column 106 so that the first piston 105 passes directly below the connecting tube 600. At this time, there is still a little air remaining in the liquid medicine between the first piston 105 and the atomizing nozzle 104. Then turn the atomizing nozzle 104 upward and push the push column 106 until the air in the first piston tube 103 between the first piston 105 and the atomizing nozzle 104 is completely discharged from the atomizing nozzle 104. Then aim the atomizing nozzle 104 at the child's oral cavity and push the push column 106 successively. Through the cooperation of the elastic strip 703 and the clamping interface 701, the liquid medicine is evenly sprayed into the child's oral cavity multiple times.

[0045] The tuning fork 300 and the servo motor 501 can both be purchased on the market. They are mature technologies in this field and have been fully disclosed. Therefore, they will not be repeated in the specification.
