A section of the surface of the moving block 38 near the nozzle switch 36... A fixing block 39 is fixedly connected to the side. When using this swab tip medication device, the swab is placed inside the placement slot 31. When the patient needs to disinfect the blood drawing site before blood is drawn, the moving block 38 drives the fixing rod 33 to rotate the push plate 32, causing the push plate 32 to move the swab and move the swab tip to the side of the nozzle 37. At the same time, the moving block 38 will drive the fixing block 39 to press the nozzle switch 36, which will compress the disinfectant in the medicine storage box 2 and spray it out through the nozzle 37 to spray disinfectant on the swab tip. Then, the swab with disinfectant is pushed along the guide plate 34 by the push plate 32 to the side of the medicine box 1 outlet to complete the medication application. The spraying method effectively avoids the swab from contaminating the unused disinfectant. After pressing, the moving block 38 is reset by the action of the spring 312.

[0029] It should be noted that nozzle 37 is a press-type nozzle. By pressing the nozzle switch 36, the piston can compress the disinfectant inside the medicine storage box 2 and spray the disinfectant out from nozzle 37.

[0030] Example 2:

[0031] Please see Figure 1-7In this embodiment, a toothed plate 310 is fixedly connected to the bottom side of the moving block 38. A gear 311 is rotatably connected inside the upper medicine box 1, and the toothed plate 310 and the gear 311 are meshed with each other. A connecting block 314 is slidably connected inside the gear 311, and one end of the connecting block 314 passes through the inside of the gear 311 and is connected to a gear disk 315 located on one side of the gear 311. One end of the fixing rod 33 is fixedly connected to a gear disk 316 that matches the gear disk 315. A spring 313 is sleeved on the surface of the connecting block 314, and the two ends of the spring 313 abut against the gear 311 and the gear disk 315 respectively.

The cross-section of 4 is T-shaped, and the inside of the fixed cylinder 45 has a sliding groove with a T-shaped structure. The arc groove of the limiting plate 41 and the position of the push plate 32 correspond to each other. When the moving block 38 presses and drives the fixed rod 33 to rotate, the support rod 44 will be driven by the elastic force of the spring 33 to drive the roller 42 to roll on the side of the limiting plate 41. When the moving block 38 presses and drives the fixed rod 33 to rotate to ninety degrees, the roller 42 will slide in the arc groove under the elastic force, so that the fixed rod 33 rotates to about 90 degrees, ensuring that the cotton swab head is pushed to the nozzle 37 to move, improving the accuracy of cotton swab pushing, ensuring the stability of the medicine on the cotton swab head, and at the same time ensuring that the cotton swab after medicine is applied is pushed to the placement rack 35 for easy use.

[0033] It should be noted that during the process of rotating the fixed rod 33 by pressing the moving block 38, the rotation angle of the fixed rod 33 is between 45° and 90°.

[0034] Through the above steps, pressing the movable block 38 can drive the fixed rod 33 to rotate, causing the push plate 32 to deliver the cotton swabs. At the same time, the movable block 38 will drive the fixed block 39 to press the nozzle switch 36, causing the nozzle 37 to spray medicine onto the cotton swab head, thus achieving medicine application to the cotton swab head. Through the cooperation of the toothed disc 1 315 and the toothed disc 2 316, the movable block 38 can be reset by the spring 1 312 after being pressed, effectively improving the efficiency of medicine application. By setting the limit mechanism 4, the limit disc 41 can be driven by the roller 42 to drive the fixed rod 33 to rotate at a certain angle, improving the accuracy of cotton swab pushing and ensuring the stability of medicine application on the cotton swab head.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
