Flexible size support: An adjustment mechanism that accommodates multiple species from cows to sheep. This functional design makes drug management more efficient across livestock with different physiological characteristics, enabling seamless use on a single device. Safety work instruments: Maintains stable fixation even in a variety of environments. The reliable design with a slip structure helps improve work efficiency and reduce handling issues during administration. Flow of drug administration: A smooth, integrated structure optimizes the flow of the chemical solution. It prevents clogging during use and delivers a more reliable and smoother drug process than conventional products. The functional design helps reduce stress for both caregivers and users. Cleaning efficiency design: Complete flat shape with zero wash. Made of nonadsorbent material, it can be easily washed with water even in frequency environments. Suitable for use in places where hygiene standards are strict due to repeated cleaning. Use scenarios Mixedspecies farming during routine dosing: Easily adjust the device to fit both cows and sheep, streamlining medication administration and reducing setup time for multispecies stock. Veterinary clinic or mobile service: Stable fixation in diverse environments minimizes slippage during drug administration, supporting safer handling and efficient workflow for caregivers. frequency cleaning facilities: Flat design and nonadsorbent material enable quick, thorough cleaning while meeting strict hygiene requirements in dairy farms, abbatoirs, or other demanding settings.
