Description

Technical Field

[0001] The present invention relates to the technical field of respiratory drug delivery, and in particular to a drug delivery device for respiratory medicine. Background Art

[0002] Respiratory infections not only affect the healthy development of children but can also lead to a variety of complications, which can be life-threatening in severe cases. Therefore, treatments for respiratory diseases, especially drug delivery methods, have become a key research focus in the medical field. Currently, the method of administering drugs by atomizing them into aerosols and inhaling them through the respiratory system has gradually attracted the attention of the medical community and patients. Major pharmaceutical companies have launched specialized drugs, adjusting their formulas to make them more suitable for aerosol inhalation. Thanks to the long-term efforts of all parties, aerosol delivery has become a common method of drug delivery.

[0003] However, although most drug delivery devices can now nebulize the patient by adding liquid medicine, when the medicine is in block or solid form, workers are required to crush the medicine and transfer it to water, and then fully stir the medicine powder scattered in the water until the medicine powder and water are evenly blended. Then, the nebulizer is connected to the patient's breathing tube for nebulization. This series of operations is not only time-consuming and labor-intensive, but also greatly increases the workload of medical staff. When the patient is in an abnormal state, such as unconsciousness, physical weakness and difficulty in cooperation, and the nasal cavity is more sensitive, the traditional mouthpiece nebulizer cannot be used. If a mask nebulizer is used directly, the atomized medicine can easily enter the nasal cavity, thereby triggering a nasal allergic reaction and causing discomfort to the patient. This undoubtedly highlights the limitations of existing drug delivery devices in clinical applications.

[0004] To this end, those skilled in the art have proposed a drug delivery device for respiratory medicine. Summary of the Invention

[0039] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0040] Example 1:

[0041] As attached Figure 1 To the attached Figure 10 As shown, the present invention provides a drug delivery device for respiratory medicine, comprising a base plate 1, the bottom of which is moved by four sets of wheels 101, a water tank 2, the front side of which is inlaid with a glass window 201, and a medicine inlet groove 202 is provided on the left side, a frame 3, which is fixedly connected to the outside of the water tank 2 and communicates with the water tank 2 through the medicine inlet groove 202, and a through groove 301 for placing medicines on the top, a crushing mechanism 4, which is arranged inside the frame 3 and is used to squeeze and crush the medicines, and a mixing mechanism 5, which is arranged inside the water tank 2 and is used to For blending the medicine powder and water, a water pump 6 is fixedly mounted on the top of the base plate 1, with its input end connected to the bottom of the water tank 2, and its output end connected to a hose 7. An atomizing mechanism 8 is provided at the end of the hose 7 away from the water pump 6, and is used for atomizing the medicine liquid. A hose 2 9 is provided at the end of the atomizing mechanism 8 away from the hose 7, and is connected to a hard tube 10. An atomizing cover 11 is movably mounted on the outside of the hard tube 10, and an internal support mechanism 13 is fixedly provided on the outside of the hard tube 10, and is used for supporting the patient's mouth.

[0042] As can be seen from the above, when using the device, the device is first moved around the patient through the four sets of wheels 101, and then the solid tablets are put into the frame 3 through the through slot 301, and then the solid tablets are crushed into powder by the crushing mechanism 4 and pushed into the water tank 2, and then appropriate clean water is injected into the water tank 2 through the external interface, and the water level is observed in real time through the glass window 201, and then the powdered medicine and clean water are fully stirred and fused by the mixing mechanism 5, and then the atomization mechanism 8 is placed on one side of the patient, so that the internal support mechanism 13 supports the patient's mouth, and then the patient's mouth is opened, and the atomization cover 11 covers the patient's mouth, and the water pump 6 is turned on. The water pump 6 draws the medicine liquid from the water tank 2, and then transports it to the inside of the atomization mechanism 8 through the hose 7, and the medicine liquid is fully atomized by the atomization mechanism 8 and discharged into the patient's mouth through the hard tube 10, which not only prevents the patient from inhaling sensitive medicine liquid through the nose, but also prevents the patient from unconsciously chewing the suction nozzle tube and causing damage to the suction nozzle tube.

[0043] Example 2:

[0044] As attached Figure 2 To the attached Figure 4As shown, this embodiment is basically the same as the previous embodiment, except that the rolling mechanism 4 includes a movable frame 401 slidably connected to the inside of the frame 3, a tooth plate 402 is fixedly connected to the inside of the movable frame 401, a fixed plate 1 403 is fixedly connected to the front and rear sides of the movable frame 401 away from one end of the frame 3, a fixed plate 2 404 is fixedly connected to the front and rear sides of the frame 3, a spring 1 405 is fixedly connected between the fixed plate 1 403 and the fixed plate 2 404 opposite thereto, a transverse mounting plate 406 is fixedly connected to the rear side of the frame 3, and a drive motor 1 407 is fixedly installed on the outer side of the transverse mounting plate 406. The output end of the driving motor 407 extends to the inner side of the horizontal mounting plate 406 and is fixedly connected to a half gear 409 through a connecting rod 408. The half gear 409 is meshed with the tooth plate 402. The movable frame 401 extends to one end of the frame 3 and is fixedly connected to a rolling plate 411 through two sets of springs 2 410. The size of the rolling plate 411 fits the inner wall of the frame 3. A limiting groove 412 is provided on the outer surface of the frame 3. The inside of the limiting groove 412 is slidably connected to a matching plate 413. A cylinder 414 is fixedly installed on the top of the frame 3, and the piston rod of the cylinder 414 is fixedly connected to the matching plate 413.

[0045] As can be seen from the above, after the solid tablet is put into the frame 3 through the through slot 301, the drive motor 1 407 is turned on, and the drive motor 1 407 drives the half gear 409 to rotate, so that the meshing tooth plate 402 drives the movable frame 401 to move inside the frame 3, and then drives the rolling plate 411 to the inside of the frame 3 through the two sets of springs 2 410 until the two sets of springs 2 410 are compressed to the maximum value, and the solid tablet is squeezed by the cooperation of the rolling plate 411 and the matching plate 413. As the half gear 409 rotates and is no longer meshed with the tooth plate 402, the spring 1 40 The mating plate 413 is pushed to move, thereby resetting the movable frame 401. The driving motor 1 407 drives the half gear 409 to rotate continuously, and the solid tablets are continuously squeezed by the rolling plate 411 and the mating plate 413 until the solid tablets are completely reduced to powder. Then, the cylinder 414 is turned on, so that the cylinder 414 drives the mating plate 413 to separate from the limiting groove 412. At this time, when the rolling plate 411 moves toward the mating plate 413, without the obstruction of the mating plate 413, the two sets of springs 2 410 drive the rolling plate 411 to push the tablet powder into the interior of the frame 3.

[0046] Example 3:

[0047] As attached Figure 5 To the attached Figure 6As shown, this embodiment is basically the same as the previous embodiment, except that the mixing mechanism 5 includes an L-shaped mounting plate 501 fixedly connected to the top of the water tank 2, and a driving motor 2 502 is fixedly installed on the top of the L-shaped mounting plate 501. The output end of the driving motor 2 502 passes through the L-shaped mounting plate 501 and is fixedly connected to a driving wheel 503. The driving wheel 503 is connected to a driven wheel 505 through a belt 504. The bottoms of the driving wheel 503 and the driven wheel 505 are both fixedly connected to a rotating rod 506. The rotating rod 506 extends to the interior of the water tank 2, and fan blades 507 are provided on opposite sides of the outer surface of the rotating rod 506.

[0048] As can be seen from the above, after the tablet powder enters the interior of the frame 3 and clean water is added, the drive motor 2 502 is turned on, and the drive motor 2 502 drives the active wheel 503 to rotate, and then drives the driven wheel 505 to rotate synchronously through the belt 504. The active wheel 503 and the driven wheel 505 drive the rotating rod 506 to rotate, and then through the revolution of the fan blade 507, the tablet powder and clean water are fully melted into liquid medicine.

[0049] Example 4:

[0050] As attached Figure 6 As shown, this embodiment is basically the same as the previous embodiment, with the difference that the atomizing mechanism 8 includes a shell 801 fixedly connected to the end of the hose 7 away from the water pump 6, a connecting groove 802 is provided on the outer side of the shell 801, the hose 7 is communicated with the shell 801 through the connecting groove 802, an inner cylinder 803 is provided inside the shell 801, the inner cylinder 803 is fixedly connected to the shell 801 through a fixing rod 804, a cavity 805 is provided between the outer diameter of the inner cylinder 803 and the inner diameter of the shell 801, a conical column 806 is provided inside the inner cylinder 803, the conical column 806 slides inside the inner cylinder 803 through a movable plate 807, a spring three 808 is fixedly connected between the movable plate 807 and the inner wall of the inner cylinder 803, a collecting cavity 809 is formed between the conical column 806 and the inner cylinder 803, and the hose two 9 is communicated with the shell 801.

[0051] As can be seen from the above, when the water pump 6 extracts the liquid medicine from the water storage tank 2 and transports it to the inside of the atomizing mechanism 8 through the hose 1 7 and the connecting groove 802, the liquid medicine will first collide with the left outer surface of the movable plate 807 to form the first atomization. As the liquid medicine flows, the liquid medicine will collide with the inner wall of the shell 801 for the second time to form the second atomization. Then, the liquid medicine flows to the left along the cavity 805 and collides with the inner wall of the shell 801 for the third time. After the collision, the liquid medicine will be blocked by the conical column 806 and will collide with the conical column 806 for the fourth time. After the fourth collision, the liquid medicine is discharged through the hose 2 9, and the liquid medicine is effectively transformed into similar atomized particles through the four-time atomization. When the collecting chamber 809 is blocked due to the atomized particles, the conical column 806 is squeezed, so that the conical column 806 slides in the inner cylinder 803 through the movable plate 807, and the spring 3 808 contracts, thereby increasing the space of the collecting chamber 809. The atomized particles blocked in the collecting chamber 809 are flushed out through the impact of subsequent atomized particles, and finally the spring 3 808 pushes the conical column 806 to reset.

[0052] Embodiment 5:

[0053] As attached Figure 8 To the attached Figure 10 As shown, this embodiment is basically the same as the previous embodiment, with the difference that the internal support mechanism 13 includes an articulated frame 1301 fixedly connected to the opposite sides of the hard tube 10, the interior of the articulated frame 1301 is rotatably connected to a connecting rod 1302, a spring five 1303 is fixedly connected between the connecting rod 1302 and the hard tube 10, and a slide groove 1001 is provided on the opposite sides of the outer surface of the hard tube 10, a spring four 12 is provided inside the slide groove 1001, one end of the spring four 12 is fixedly connected to the inner wall of the hard tube 10, and the other end of the spring four 12 is fixedly connected to the atomizing hood 11.

[0054] As can be seen from the above, when connecting the nebulizer 11 to the patient's mouth, the doctor needs to hold the nebulizer 11 with one hand and pull it to the left. The nebulizer 11 compresses the spring four 12, so that the nebulizer 11 moves to the left along the slide groove 1001 until the inner support mechanism 13 is completely exposed. Then, the doctor holds the two side connecting rods 1302 with the other hand, and closes the two side connecting rods 1302 through the cooperation of the hinge frame 1301, and compresses the spring five 1303 until the doctor inserts the two side connecting rods 1302 into the patient's mouth. Then, the doctor releases the two side connecting rods 1302. The two side connecting rods 1302 are pushed by the spring five 1303 to make them collide with the patient's mouth, thereby fixing the hard tube 10 in the patient's inner cavity. Then, the nebulizer 11 is released. Under the push of the spring four 12, the nebulizer 11 is sealed with the patient's mouth, thereby completing the wearing of the nebulizer 11.

[0055] Working principle: When using the device, first move the device around the patient through the four sets of wheel bodies 101, then put the solid tablet into the frame 3 through the through slot 301, turn on the drive motor 1 407, and the drive motor 1 407 drives the half gear 409 to rotate, so that the meshing tooth plate 402 drives the movable frame 401 to move inside the frame 3, and then drives the rolling plate 411 into the frame 3 through the two sets of springs 2 410 until the two sets of springs 2 410 are compressed to the maximum value, and the solid tablet is squeezed by the cooperation of the rolling plate 411 and the matching plate 413. As the half gear 409 rotates and the tooth plate When 402 is not engaged, the spring 1 405 pushes the matching plate 413 to move, and then the movable frame 401 is reset. The driving motor 1 407 drives the half gear 409 to rotate continuously, and the solid tablets are continuously squeezed by the rolling plate 411 and the matching plate 413 until the solid tablets are completely turned into powder. Then the cylinder 414 is turned on, so that the cylinder 414 drives the matching plate 413 to disengage from the limiting groove 412. At this time, when the rolling plate 411 moves toward the matching plate 413, since there is no obstruction from the matching plate 413, the two sets of springs 2 410 drive the rolling plate 411 to push the tablet powder into the interior of the frame 3.

[0056] Then, an appropriate amount of clean water is injected into the water tank 2 through the external interface, and the water level is observed in real time through the glass window 201. The second drive motor 502 is turned on, which drives the driving wheel 503 to rotate, and then drives the driven wheel 505 to rotate synchronously through the belt 504. The driving wheel 503 and the driven wheel 505 drive the rotating rod 506 to rotate, and then the fan blade 507 revolves, so that the tablet powder and the clean water are fully dissolved into liquid medicine.

[0057] Then put the atomizer mechanism 8 into the patient's side. The doctor needs to hold the atomizer mask 11 with one hand and pull it to the left. The atomizer mask 11 compresses the spring four 12, so that the atomizer mask 11 moves to the left along the slide groove 1001 until the inner support mechanism 13 is completely exposed. Then, the doctor holds the two side connecting rods 1302 with the other hand, closes the two side connecting rods 1302 through the cooperation of the hinge frame 1301, and compresses the spring five 1303 until the doctor inserts the two side connecting rods 1302 into the patient's mouth. Then, loosen the two side connecting rods 1302. The two side connecting rods 1302 are pushed by the spring five 1303 to make them collide with the patient's mouth, thereby fixing the hard tube 10 in the patient's inner cavity. Then loosen the atomizer mask 11. Under the push of the spring four 12, the atomizer mask 11 is sealed with the patient's mouth, thereby completing the wearing of the atomizer mask 11.

[0058] When the water pump 6 is turned on and draws the liquid medicine from the water storage tank 2 and delivers it to the inside of the atomizing mechanism 8 through the hose 1 7 and the connecting groove 802, the liquid medicine will first collide with the left outer surface of the movable plate 807 to form the first atomization. As the liquid medicine flows, the liquid medicine will collide with the inner wall of the shell 801 for the second time to form the second atomization. Then, the liquid medicine flows to the left along the cavity 805 and collides with the inner wall of the shell 801 for the third time. After the collision, the liquid medicine is blocked by the conical column 806 and collides with the conical column 806 for the fourth time and is discharged through the hose 2 9. The liquid medicine is effectively transformed into a liquid medicine through the four atomizations. The atomized particles are similar, and when the collecting chamber 809 is blocked by the atomized particles, the conical column 806 will be squeezed, so that the conical column 806 slides in the inner cylinder 803 through the movable plate 807, and the spring three 808 contracts, thereby increasing the space of the collecting chamber 809, thereby flushing out the atomized particles blocked in the collecting chamber 809 through the impact of subsequent atomized particles, and finally the spring three 808 pushes the conical column 806 to reset, and the atomized particles are finally discharged into the patient's mouth through the hard tube 10, which not only prevents the patient from inhaling sensitive medicine through the nose, but also prevents the patient from chewing the suction nozzle tube unconsciously and causing damage to the suction nozzle tube.
