When in use, the medical staff presses the moving block 8 downward when applying medicine to the patient. At this time, the card block 10 is driven by the moving block 8 to leave the range of the card slot 7. Further, the medical staff can push the moving block 8 in the direction of the medicine storage tube 2, thereby driving the push rod 3 to move synchronously with the moving block 8. When the card block 10 moves to the next card slot 7 with the moving block 8, the moving block 8 is released. Further, under the elastic force of the three springs 5 ​​themselves, the moving block 8 is pushed upward. During the lifting process, the card block 10 will engage with the card slot 7 to prevent the moving block 8 from continuous displacement, thereby achieving precise control of the amount of medicine.

[0024] Reference Figure 1 and Figure 4 A medicine outlet hole 11 is formed through the outer wall of the end of the shell 1 away from the connecting groove 4. The medicine outlet hole 11 is located at the end of the shell 1 away from the connecting groove 4. When the moving block 8 pushes the pushing rod 3 to move, as the pushing rod 3 continues to move, the medicine stored in the medicine storage tube 2 will be discharged along the medicine outlet hole 11, so as to facilitate medical staff to apply the medicine.

[0025] Reference Figure 1The outer wall of one end of the shell 1 near the medicine outlet 11 is fixedly connected with a fixing plate 12, and the outer wall of the fixing plate 12 is rotatably connected with a smear roller 13. The smear roller 13 is located outside the medicine outlet 11. When the medicine is discharged along the medicine outlet 11, the medicine will first contact the smear roller 13. When the medical staff applies the medicine, the smear roller 13 can evenly apply the medicine to the patient's skin, so that the patient can fully absorb the medicine.

[0026] Reference Figure 3 A connecting hole 9 is provided on the bottom wall of the moving block 8, and there are three connecting holes 9. The positions of the three connecting holes 9 correspond to the positions of the three positioning columns 6 one by one, and the inner walls of the three connecting holes 9 are adapted to the outer walls of the three positioning columns 6. When in use, the staff presses the moving block 8, and the three positioning columns 6 are inserted into the inside of the three connecting holes 9, thereby limiting the moving block 8 to prevent the position of the moving block 8 and the connecting groove 4 from being offset when the staff pushes the moving block 8 to move.

[0027] Reference Figure 4 The outer wall of the shell 1 is provided with a slide groove 14, and the shell 1 is slidably connected to a slide plate 15 through the slide groove 14. When the slide plate 15 is in use, the staff can slide the slide plate 15 to one side to observe the interior of the shell 1 and facilitate cleaning the interior of the shell 1.

[0028] Reference Figure 4 The outer wall of the medicine storage tube 2 near the sliding plate 15 is threadedly connected with a threaded plug 16. When in use, the staff can remove the threaded plug 16 to add medicine to the inside of the medicine storage tube 2, or clean the inside of the medicine storage tube 2 after use to avoid drug residue.

[0029] Reference Figure 4 The outer wall of the sliding plate 15 is fixedly connected with a sliding block 17, and the sliding block 17 is located at one end of the sliding plate 15, so that the staff can use the force when sliding the sliding plate 15, thereby improving the work efficiency of the staff.

[0030] Working principle: when in use, the medical staff presses the moving block 8 downward, at which time the card block 10 is driven by the moving block 8 to break away from the range of the card slot 7, thereby releasing the lock of the card slot 7 on the moving block 8. Further, the medical staff can push the moving block 8 in the direction of the drug storage tube 2, thereby driving the push rod 3 to move synchronously with the moving block 8. When the card block 10 moves to the next card slot 7 with the moving block 8, the moving block 8 is released. Further, under the elastic force of the three springs 5 ​​themselves, the moving block 8 is pushed upward. During the lifting process, the card block 10 will engage with the card slot 7 to prevent the moving block 8 from continuously moving. At the same time, when the moving block 8 drives the push rod 3 to move, the push rod 3 squeezes the medicine inside the drug storage tube 2, so that the medicine is discharged along the medicine outlet 11, thereby realizing accurate control of the medicine amount. After the discharged medicine contacts the smearing roller 13, the medical staff uses the smearing roller 13 to apply the medicine. Since the smearing roller 13 rolls during the smearing process, the medicine can be more evenly applied to the patient's skin, thereby improving the patient's treatment efficiency.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
