Development and Performance Analysis of an Electromagnetic Needle-Free Jet Injection Device for Efficient Drug Delivery in Pig Farms
Abstract
This research addresses the challenges of traditional needle-based injections in pig farms, such as syringe breakage, drug residue, and stress-induced handling, which compromise animal welfare and meat quality. The aim is to develop an electromagnetic needle-free jet injector to provide a safer and more efficient drug delivery method. The device was designed using an electromagnetic actuator and optimized through MATLAB simulations, Polyvinylidene Fluoride (PVDF) pressure sensors, and high-speed video imaging. The device generated a high-speed jet using electromagnetic fields and neodymium iron boron (NdFeB) magnets. Calibration and impact pressure measurements are adopted to validate its performance. Results showed that the injector can generate jet speed up to 225 m/s and impact pressures exceeding 35 MPa, meeting the thresholds for effective drug delivery. Both simulation and experimental data also confirmed the reliability of the device. The polyacrylamide gel and porcine tissue results indicate precise and consistent drug delivery. The key findings highlight the ability of the device to maintain sufficient impact pressure and jet speed, making it suitable for veterinary and human medical applications. High-speed video analysis reveals an essential jet behavior for effective drug delivery, robust performance, and deep tissue penetration. Finally, this research shows that the injector significantly improves drug delivery in pig farms, offering a viable alternative to traditional injections by reducing contamination risks and stress while enhancing efficiency.
