Description

Technical Field

[0001] This utility model relates to the field of animal drug delivery device technology, specifically to an auxiliary device for drug delivery to rodent wounds. Background Technology

[0002] Currently, with the development of biological and pharmaceutical technologies, animal experiments have become a basic experimental method in biology and medicine. Before drugs are used clinically in humans, they usually need to be studied using experimental animals, such as rodents like mice, rats, and rabbits, to investigate their pharmacodynamics, pharmacology, and toxicology.

[0003] Rodent wound recovery models have been widely used for wound healing and skin regeneration. However, the following technical challenges are common in wound repair research: 1) Difficulty in controlling the healing mechanism. Human wound healing primarily involves the crawling action of epidermal cells, granulation tissue formation, and self-repair of epithelial tissue. However, in rodents, wound healing mainly involves the contraction and crawling of the skin around the wound, with contraction even outweighing crawling in some rodents, such as rats. Therefore, researchers often use silicone rings to fix the wound and prevent fascia contraction, mimicking the human wound healing mechanism. Suturing requires considerable skill from the operator, and the discomfort caused by suturing can easily exacerbate scratching or rubbing against the wound by the animal; 2) Difficulty in caring for animal wound models. After successful wound modeling in small animals, many studies require continuous drug administration to the wound and real-time observation and tracking of wound healing. Furthermore, small animals may scratch or rub against the wound during rearing. Researchers often use gauze wrapping or other methods to protect wounds, which is not conducive to observing wound healing, and the dressing change process can easily cause secondary damage to the wound; 3) Some drugs in the form of solution or gel are not easy to stay in the wound.

[0004] Chinese utility model patent CN203107993U discloses a skin-administered occlusive patch. The patch has an adhesive layer with a drug-holding groove at its center. A plastic gasket is located at the edge of the drug-holding groove near the adhesive layer, ensuring the gasket adheres tightly to the skin during use. This patented occlusive patch isolates the medication from the external environment, preventing evaporation and allowing it to hold liquid medications without leakage, thus maintaining efficacy and achieving the desired drug delivery effect. However, this patent also has drawbacks, including the inability to continuously administer medication and the inability to be reused. Summary of the Invention

Figure 1-3 The present invention will be further described below. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] See Figure 1-3 A rodent wound drug delivery aid device includes an annular fixing ring 1 for fixing to the outside of the rodent wound, an annular silicone sleeve 2 covering the outside of the annular fixing ring 1, and at least one fixing strap 3 connected to the side of the annular silicone sleeve 2. The bottom of the annular silicone sleeve 2 is attached with an adhesive layer 4. The inside of the annular fixing ring 1 is a drug delivery port 11. The annular fixing ring 1 is equipped with a protective cover 5 for covering the drug delivery port 11.

[0023] This utility model's rodent wound medication administration aid device features an annular silicone sleeve 2 covering the outside of the annular fixing ring 1, making contact with the rodent's skin more comfortable. The use of an adhesive layer 4 and a fixing strap 3 ensures the annular fixing ring 1 is securely fixed to the rodent. A protective cover 5 covering the administration port 11 isolates the medication from the outside environment, preventing the rodent from dislodging the medication during movement, reducing drug evaporation, and preventing drug contamination. It allows for repeated administration and multiple uses, reducing costs. The device is simple in structure and easy to use.
