DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1

[0027] Reference Figure 1-Figure 5 A drug delivery device suitable for paste-like medicines includes a drug delivery mechanism, which includes a drug delivery barrel 1. The inner wall of the drug delivery barrel 1 is sealed and slidably connected with a sliding plug 3. The inner wall of the drug delivery barrel 1 away from the sliding plug 3 is fixedly connected with a conical tube 2. The side wall of the conical tube 2 is provided with a plurality of grooves 4. The inner wall of the conical tube 2 is provided with a drug outlet hole 5 connected with the inner wall of the groove 4. The side wall of the conical tube 2 is provided with a tube cover 6. The side wall of the drug delivery barrel 1 away from the conical tube 2 is provided with a thread.

[0028] Furthermore, when the drug delivery cartridge 1 is not in use, a sealing cap is threadedly connected to the drug delivery cartridge 1 to protect the sliding plug 3 .

[0029] The groove 4 is provided so that the paste medicine squeezed out from the medicine outlet 5 is stored in the groove 4. At this time, the operator can control the movement of the first operating cylinder 7 so that the paste medicine in the groove 4 is evenly applied to the nasal passages or some natural channels to increase its application effect.

[0030] The pushing mechanism is used to push the slide plug 3 to slide on the inner wall of the dosing cylinder 1. The pushing mechanism includes a first operating cylinder 7. The inner wall of the first operating cylinder 7 is fixedly connected to the first support ring 8. The inner side wall of the first support ring 8 is slidably connected to the reciprocating threaded cylinder 9. The inner wall of the first operating cylinder 7 is fixedly connected to the second support ring 10. The inner wall of the second support ring 10 is fixedly connected to the motor 11. The movable end of the motor 11 is fixedly connected to the threaded column 12. The side wall of the threaded column 12 is threadedly connected to the inner wall of the reciprocating threaded cylinder 9. The side wall of the dosing cylinder 1 is threadedly connected to the inner wall of the first operating cylinder 7.

[0031] Furthermore, when it is needed, the driving motor 11 rotates clockwise, driving the threaded column 12 to rotate clockwise, driving the reciprocating threaded cylinder 9 to move to the left. At this time, the paste medicine can be squeezed out through the sliding plug 3 to complete the application of the patient's nasal passages or some natural channels, and the speed and time of the motor 11 can control the speed and amount of applying the paste. The operation is simple, avoiding the use of syringes in the existing technology, which does not require patients to operate themselves. At the same time, it is not easy to control the amount of medicine used.

[0032] A battery 13 is fixedly connected to the inner wall of the first operating cylinder 7 . A circuit board 14 is installed in the first operating cylinder 7 . A button 16 is provided on the circuit board 14 . The motor 11 , the battery 13 , the circuit board 14 and the button 16 are electrically connected.

[0033] A switch button 15 is installed on the side wall of the first operating tube 7 facing the button 16. The side wall of the switch button 15 is in contact with the side wall of the button 16. When the switch button 15 is pressed, the button 16 is pressed, and the circuit on the motor 11 is turned on, so that the motor 11 is powered. When the switch button 15 is released, the button 16 is released, the circuit on the motor 11 is disconnected, and the motor 11 stops rotating. The control methods are all existing technologies.

[0034] A charging socket 17 is installed at the bottom of the first operating tube 7 . The charging socket 17 is electrically connected to the battery 13 , so as to replenish the power in the battery 13 .

[0035] When the drug delivery device is in use, the paste medicine is stored in the drug delivery tube 1, and then the drug delivery tube 1 is threadedly connected to the first operating tube 7, and the tube cover 6 is removed;

[0036] During use, the patient holds the first operating cylinder 7, brings the conical tube 2 into contact with the area where the medicine needs to be applied, and then presses the switch button 15. At this time, the button 16 is pressed. At this time, the circuit on the motor 11 is turned on, so that the motor 11 is energized, driving the motor 11 to rotate clockwise, driving the threaded column 12 to rotate clockwise, and driving the reciprocating threaded cylinder 9 to move left. At this time, the paste medicine can be squeezed out through the slide plug 3. At this time, the paste medicine squeezed out from the medicine outlet 5 is stored in the groove 4. At this time, the operator can control the movement of the first operating cylinder 7 to evenly apply the paste medicine in the groove 4 to the nasal passage or some natural passages, thereby increasing its application effect and completing the application of the patient's nasal passage or some natural passages;

[0037] When the switch button 15 is released, the button 16 is released, the circuit on the motor 11 is disconnected, and the motor 11 stops rotating. At this time, the paste medicine will not be squeezed out;

[0038] In this way, the speed and time of the motor 11 can control the speed and amount of applying the paste medicine, which is simple to operate and avoids the use of syringes in the existing technology. Patients do not need to operate it themselves, and it is not easy to control the amount of medicine used.

[0039] Example 2

[0040] Reference Figure 6-Figure 7 , different from the first embodiment, the pushing mechanism includes a second operating cylinder 18, the inner wall of the second operating cylinder 18 is slidably connected to a push rod 19, the push rod 19 is fixedly connected to a handle 20 away from the side wall of the second operating cylinder 18, and the side wall of the dosing cylinder 1 is threadedly connected to the inner wall of the second operating cylinder 18.

[0041] When administering the medicine, the dosing tube 1 and the second operating tube 18 can also be threadedly connected, and the tube cover 6 can be removed. Then the user can contact the conical tube 2 with the area where the medicine needs to be applied, and then press the handle 20. At this time, the push rod 19 presses the slide plug 3 to squeeze out the paste medicine. In this way, the user can manually administer the medicine without using electric dosing, which increases the scope of use of the dosing device.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
