Description

Technical Field

[0001] The utility model relates to the technical field of animal transdermal drug administration, in particular to an animal back skin drug administration fixing device. Background Art

[0002] Transdermal drug delivery systems, referred to as TDDs, or transdermal therapeutic systems, referred to as TTS, are a method of drug absorption through the skin. Drugs are absorbed through the skin into the animal's blood circulation and reach effective blood drug concentrations. It is a new way of drug administration to treat or prevent animal diseases. When administering drugs, sometimes a fixing device is needed to ensure the stability of drug administration on the animal's back skin.

[0003] After searching, it was found that there is a drug administration fixing device for the back skin of an animal with a publication number of CN219089758U, which includes a strap and a binding strip. The strap is provided with four binding strips, which are used to solve the problem of using adhesive tape to wrap around the animal for a long time, causing skin redness and swelling, bruising, being not conducive to the observation of skin irritation, and making the animal uncomfortable, while greatly increasing the test time of the experimenter. In this practice, the strap is in direct contact with the animal's back skin, which can easily lead to cross-contamination between the animal's back skin, the drug solution and the fixing device, affecting the health of the animal's back skin. For this reason, we propose an animal back skin drug administration fixing device. Utility Model Content

The first strap 4 and the second strap 6 are sewn to the two sides of the patch 1 through the stitches 2. By adjusting the button 15 on the second strap 6 and the buckle with the opening 14, the length of the second strap 6 can be appropriately shortened, so as to achieve the purpose of being suitable for animals of different body sizes. Then, the staff adheres the composite dressing 8 to the dressing slot 3 of the patch 1 through the adhesive tape 9, so that when the patch 1 contacts the medication site on the back of the affected animal, the composite dressing 8 serves as an antibacterial protection structure. Then, the fiber cloth 10 in the composite dressing 8 serves as the basic structure for use. The structure of the composite dressing 8 is kept stable. The SAP bonding layer 11 arranged on the composite dressing 8 can actively absorb wound exudate and necrotic tissue, keep the animal's back skin dry and clean, and prevent cross-contamination between the animal's back skin, the medicine and the patch 1. Then the staff will bind the animal through the Velcro 7 on the second strap 6 on both sides of the patch 1 and the felt 5 on the first strap 4. Finally, a semi-annular silicone ring 12 is also provided at the contact position between the two ends of the patch 1 and the animal's back skin, which can enhance the fit between the two ends of the patch 1 and the animal's back skin and reduce sliding. The silicone ring 12 can exchange gas through the air hole 13 to reduce discomfort on the animal's back skin.
