Needle-Free Veterinary Injector for Livestock

The Needle-Free Veterinary Injector is a professional livestock vaccination and medication device designed to deliver liquid through the skin without using conventional injection needles. A controlled high-pressure liquid jet penetrates the skin and delivers the required dose into the target tissue.

Designed for intensive livestock operations, the system provides accurate dosing, adjustable injection settings and high working efficiency. Needle-free operation helps reduce broken-needle risks, accidental needle-stick injuries and contamination associated with repeated needle use.

• Needle-free injector handpiece and nozzle assembly
• Medicine reservoir and liquid delivery system
• Pneumatic injection equipment for commercial livestock farms
• Livestock vaccination and veterinary treatment applications

• Needle-Free Delivery: High-pressure liquid jet delivers medication without conventional metal needles.
• Accurate Dosing: Controlled metering helps provide consistent medication volume and reduce unnecessary drug waste.
• Adjustable Injection Depth: Suitable for different animal sizes and treatment requirements.
• Improved Biosecurity: Helps reduce biological contamination associated with repeated needle use.
• No Broken Needles: Eliminates the risk of needle fragments remaining in animal tissue.
• Reduced Handling Stress: Fast injection supports efficient livestock handling and vaccination.
• High Working Efficiency: Suitable for large-scale vaccination programs on commercial farms.
• Pneumatic Operation: Compatible with regulated compressed air or CO2 according to system configuration.

The injector uses compressed air or CO2 as its power source. When activated, pneumatic pressure rapidly forces a precisely measured quantity of medication through a small nozzle opening, producing a high-velocity liquid micro-jet.

The liquid jet penetrates the skin without a metal needle and delivers medication into the required tissue depth. Dose and operating settings can be selected according to animal size, medication type and treatment requirements.

• Connect the injector to a clean and properly regulated compressed-air or CO2 supply.
• Install the medication container and ensure all liquid tubes and fittings are securely connected.
• Select the required injection dose and operating settings before use.
• Prime the medication circuit and confirm stable liquid delivery before routine vaccination.
• Position the injector correctly against the recommended injection site during operation.
• Clean the nozzle, medication pathway and reservoir connection after each working session.
• Inspect seals, tubing, connectors and moving components regularly.
• Replace worn seals and accessories when required.
• Store the injector in a clean, dry and protected environment when not in use.

Q: How does the needle-free veterinary injector work?
A: It uses pneumatic energy to generate a high-speed liquid jet that delivers medication through the skin without using a conventional metal needle.

Q: What injection doses are available?
A: Available configurations include 0.5 ml, 1.0 ml, 1.5 ml and 2.0 ml.

Q: What power source does the injector require?
A: The pneumatic system can operate with regulated compressed air or CO2 according to the selected configuration.

Q: What are the main advantages compared with conventional needles?
A: Needle-free injection eliminates broken-needle risks and helps reduce needle-stick injuries, needle handling and contamination associated with repeated needle use.

Q: Can it be used for livestock vaccines and veterinary medicines?
A: It can be used with compatible liquid veterinary products when the medication is approved for the intended administration route. Always follow veterinary and pharmaceutical instructions.

Q: Is the injection depth adjustable?
A: Yes. Operating settings can be configured according to animal size, injection requirements and selected equipment configuration.

Q: Is OEM or customized configuration available?
A: Yes. Dose configuration, accessories, packaging and other specifications can be customized according to distributor, farm and project requirements.
