[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-3 A procaterol hydrochloride solid dosage form delivery device includes a delivery cylinder 1, a grinding base 2 fixedly disposed in the middle of the delivery cylinder 1, a filter screen 3 fixedly connected between the grinding base 2 and the delivery cylinder 1, a screw-in cylinder 4 threadedly fitted at one end of the delivery cylinder 1, a grinding block 5 fixedly connected to the end of the screw-in cylinder 4 facing the grinding base 2, a placement port 6 for placing the drug is opened on the side of the delivery cylinder 1 at one end of the screw-in cylinder 4, and a sealing component 7 is provided in the placement port 6, and an air blowing component for supplying air to the delivery cylinder 1 from the outside is provided at the other end of the screw-in cylinder 4.

[0024] In use, the procaterol hydrochloride solid dosage form delivery device first places the procaterol hydrochloride solid dosage form into the delivery cartridge 1 through the placement port 6 and places it on the grinding base 2. The placement port 6 is then sealed by the sealing component 7. Holding the delivery cartridge 1 with one hand, the other hand rotates the feed tube 4 until the grinding block 5 presses against the solid dosage form. Continuing to rotate the feed tube 4, the grinding block 5, in conjunction with the grinding base 2, grinds the solid dosage form into powder. After this, the feed tube 4 is rotated in the opposite direction by 1-5 mm. The delivery cartridge 1 is then horizontalized and gently shaken. The powder moves to the filter screen 3, where the airflow from the blowing component blows the powder through the filter screen 3 and out from the end of the delivery cartridge 1 away from the feed tube 4.

[0025] Reference Figures 2-4 A fixing frame 8 is fixedly connected to the middle of the drug delivery cartridge 1, and the grinding base 2 is fixedly connected to the middle of the fixing frame 8. Multiple filter screens 3 are fixedly connected to the side of the fixing frame 8, and the multiple filter screens 3 are arranged in a circumferential array on the outside of the grinding base 2. The drug delivery cartridge 1 is fixed to the grinding base 2 and the filter screens 3 by the fixing frame 8. The circumferential array of filter screens 3 can improve the flexibility of operation, and at the same time, the air blowing component blows the powder on the filter screens 3 out.

[0026] To improve the stability and grinding effect of solid dosage forms on the grinding base 2, the side of the grinding base 2 facing the grinding block 5 is recessed inward, the inner wall of the recessed part of the grinding base 2 is inclined, and the edge of the grinding block 5 facing the grinding base 2 is chamfered to facilitate the movement of the ground powder to the filter screen 3.

[0027] A sealing ring 9 is fixedly provided at the connection between the fixed frame 8 and the drug delivery cylinder 1 on the side facing the screw-in cylinder 4. The sealing ring 9 prevents powder from entering the gap between the drug delivery cylinder 1 and the screw-in cylinder 4 during the blowing process. Since the screw-in cylinder 4 rotates a certain distance in the opposite direction before the blowing step, the sealing ring 9 should have a certain elasticity to meet the sealing requirements during the blowing process.

[0028] Reference Figures 1-3 In order to facilitate the rotation of the screw-in cylinder 4, an auxiliary ring 10 is fixedly sleeved on one side of the screw-in cylinder 4 outside the drug delivery cylinder 1. In addition, the auxiliary ring 10 can also limit the drug delivery cylinder 1, thereby preventing the grinding block 5 from directly acting on the grinding base 2 and improving the practicality and stability of the device.

[0029] The air blowing assembly includes an airbag 11 fixedly disposed at one end of the spiral tube 4 facing away from the drug delivery tube 1. The spiral tube 4 has a cavity 12 inside. A first one-way valve 13 is provided on one side of the auxiliary ring 10 to allow air to enter the cavity 12. A second one-way valve 14 is fixedly disposed at one end of the cavity 12 away from the airbag 11 to supply air to the filter screen 3. By cooperating with the first one-way valve 13 and the second one-way valve 14, the airflow enters the spiral tube 4 from the outside and blows towards the filter screen 3.

[0030] Reference Figures 2-4 Since multiple filters 3 are arranged in a circular array, in order to improve the uniformity of air blowing on the filters 3, the spiral tube 4 has multiple air outlets 15 arranged in a circular array at one end facing the filters 3. All the air outlets 15 are connected to the air outlet side of the second one-way valve 14 to improve the drug delivery effect.

[0031] The end of the drug delivery cartridge 1 away from the screw-in cartridge 4 is detachably connected to a nozzle 16 via a thread. The nozzle 16 is used to concentrate the drug. The detachable nozzles 16 of different shapes can meet different needs in actual use and improve practicality.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
