[0018] See also Figure 1-Figure 3The utility model discloses a drug delivery device for external anthelmintic drops for dogs and cats, comprising a medicine liquid cylinder 1, a scale line 2 is arranged on the outer wall of the medicine liquid cylinder 1, a liquid outlet 3 is arranged at the head end of the medicine liquid cylinder 1, and a protective cap 4 is threadedly installed at the liquid outlet 3, a polypropylene gasket 5 is installed in the protective cap 4, a polypropylene piston 6 is slidably installed in the medicine liquid cylinder 1, and a polyethylene push rod 7 is connected to the tail of the polypropylene piston 6, a sealing cap 8 is clamped at the tail end of the medicine liquid cylinder 1, a sealing sleeve 9 is clamped on the inner end face of the sealing cap 8, the sealing cap 8 is slidably sleeved with the polyethylene push rod 7, and a plastic Screw 10 is fastened to the polyethylene push rod 7 through the plastic screw 10. A scale line 2 is provided on the medicine liquid cylinder 1, which is used to mark the dosage. In this way, the dosage for each time can be calculated according to the weight of the dog or cat to avoid overuse or underuse. After each use, there is a protective cap 4 and a polypropylene gasket 5 at the liquid outlet 3, which can be completely sealed to avoid oxidation and deterioration caused by air entering. The tail of the medicine liquid cylinder 1 is clamped with a sealing cap 8 and a built-in sealing sleeve 9, which can provide a good sealing effect. The sealing cap 8 can be fastened to the polyethylene push rod 7 through the plastic screw 10 to prevent misoperation of the push rod after use.
