Abstract
Description
Technical Field
[0001] This utility model relates to the field of veterinary medical device technology, specifically to an enrofloxacin injection device. Background Technology
[0002] Enrofloxacin is a quinolone antibiotic for animal use. Due to its unique mechanism of action, it is effective against most pathogens and belongs to the broad-spectrum bactericidal class of antibiotics. It has excellent killing effects on common pathogens such as Escherichia coli, Salmonella, Haemophilus influenzae, Pasteurella multocida, Staphylococcus aureus, Mycoplasma, and Chlamydia, and is particularly effective against Mycoplasma. It also has a strong killing effect on Mycoplasma resistant to tylosin and tiamulin. It has a low minimum inhibitory concentration (MIC) against most pathogens, playing an important role in the prevention and treatment of bacterial diseases and Mycoplasma infections. Enrofloxacin is rapidly absorbed by intramuscular and oral administration and is widely distributed in the body, especially at high concentrations in lung tissue and the urogenital tract. Therefore, it is mainly used in veterinary clinical practice to treat respiratory and urogenital diseases caused by bacteria and Mycoplasma.
[0003] When enrofloxacin is administered via intramuscular injection, an injection device is used. Traditional injection devices do not have the function of limiting the depth of needle insertion. If the needle is inserted too far into the animal's body, it can easily cause significant discomfort to the animal, thereby affecting the efficacy of the enrofloxacin injection. Utility Model Content

Detailed Implementation
[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0028] like Figures 1-5As shown, this utility model provides a technical solution: an enrofloxacin injection device, including a drug storage cylinder 1, a needle limiting mechanism 2 disposed on the left side of the drug storage cylinder 1, an auxiliary injection mechanism 3 disposed on the drug storage cylinder 1, the needle limiting mechanism 2 including a hollow plate 21, a sliding plate 22 movably connected to the inner wall of the hollow plate 21, a locking bolt 23 threadedly connected to the outer wall of the hollow plate 21, the threaded end of the locking bolt 23 movably connected to the outer wall of the sliding plate 22, a receiving block 25 fixedly installed on the left side of the sliding plate 22, an arc-shaped limiting member 26 fixedly installed on the left side of the receiving block 25, and a connecting foot 24 welded to the outer wall of the hollow plate 21, the connecting foot 24 being detachable. When the needle body 274 is inserted into the animal body and attached to the left side of the drug storage cylinder 1, the arc-shaped limiting member 26 will fit against the animal's skin to limit the length of the needle body 274 insertion, preventing the needle body 274 from being inserted too far and causing great discomfort to the animal, thus ensuring the stability of enrofloxacin injection. By loosening the gap of the locking bolt 23, the position of the sliding plate 22 can be adjusted in the inner cavity of the hollow plate 21, and the position of the arc-shaped limiting member 26 can be adjusted relative to the needle body 274 to adjust the limiting position. The connecting foot 24 is installed on the drug storage cylinder 1 by screws. If the limiting is not required, the hollow plate 21 can be completely removed.
[0029] As one implementation method in this embodiment, such as Figure 1 , Figure 3 As shown, the needle limiting mechanism 2 also includes a protruding tube 27, which is fixedly connected to the center of the left side of the drug storage cylinder 1. An elastic plastic clip 271 is fixedly installed on the left side of the protruding tube 27. A rubber ring 272 is fixedly sleeved on the outer wall of the protruding tube 27. A connecting cylinder 273 is movably inserted into the left side of the protruding tube 27. The outer wall of the connecting cylinder 273 is movably connected to the inner wall of the elastic plastic clip 271, and the outer wall of the rubber ring 272 is movably connected to the inner wall of the connecting cylinder 273. The needle body 274 is fixedly connected to the left side of the tube 273. The connecting tube 273 is inserted into the left side of the protruding tube 27. The elastic plastic clip 271 can lock the connecting tube 273 onto the protruding tube 27. The rubber ring 272 can seal the connection between the protruding tube 27 and the connecting tube 273. The user can pull the connecting tube 273 out from the left side of the protruding tube 27 by applying force again, which makes it convenient for the user to replace the needle body 274 after use.
[0030] As one implementation method in this embodiment, such as Figure 1 , Figure 4 , Figure 5As shown, the auxiliary injection mechanism 3 includes a support block 31, which is fixedly installed on the back of the drug storage cylinder 1. An electric telescopic rod 32 is fixedly installed on the back of the support block 31. A transmission bent rod 33 is fixedly connected to the telescopic end of the electric telescopic rod 32. A sliding shaft 34 is fixedly connected to the end of the transmission bent rod 33 away from the electric telescopic rod 32. The left side of the sliding shaft 34 extends into the inner cavity of the drug storage cylinder 1 and is fixedly connected to a sealing slider 35. The outer wall of the sealing slider 35 is slidably connected to the inner wall of the drug storage cylinder 1. The auxiliary injection mechanism 3 also includes a battery compartment 36, which is fixedly installed on the outer wall of the drug storage cylinder 1. A silicone sleeve 361 is fixedly fitted onto the outer wall of the battery compartment 36. A battery body 362 is detachably connected to the inner cavity of the battery compartment 36. The battery body 362 is used to power the electric telescopic rod 32. A movable cover 363 is movably inserted into the end of the battery compartment 36 away from the drug storage cylinder 1. A connecting bolt 364 is threaded onto the wall, and the threaded end of the connecting bolt 364 is movably connected to the outer wall of the movable cover 363. The electric telescopic rod 32 is extended, and the sliding shaft 34 is driven to slide to the right through the transmission of the transmission rod 33. Simultaneously, the sealing slider 35 slides to the right in the inner cavity of the drug storage cylinder 1. During this process, enrofloxacin can be absorbed from the left side of the drug storage cylinder 1. The electric telescopic rod 32 is then retracted, which can drive the sealing slider 35 to slide to the left, thereby realizing the function of automatic injection. This design can significantly reduce the manpower consumption when injecting multiple animals at the same time. The design of the battery compartment 36 and the silicone sleeve 361 makes it easy for users to hold the structure firmly. The design of the connecting bolt 364 locks the movable cover 363 to the end of the battery compartment 36. After the movable cover 363 is removed, the depleted battery body 362 can be disassembled and replaced.
[0031] Working principle: During use, the electric telescopic rod 32 is extended, and through the transmission of the transmission rod 33 and the sliding shaft 34, the sealing slider 35 is driven to slide to the right in the inner cavity of the drug storage cylinder 1. During this process, enrofloxacin can be absorbed from the left side of the drug storage cylinder 1. Then, the needle body 274 is inserted into the animal's body. The arc-shaped limiting piece 26 will then fit against the animal's skin to limit the length of the needle body 274 inserted. Immediately afterwards, the electric telescopic rod 32 is controlled to return to its original position and retract, which can drive the sealing slider 35 to slide to the left, thereby realizing the function of automatic injection of enrofloxacin.
[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
