In the veterinary pharmaceutical industry, packaging is not just a container but a key factor in ensuring drug quality, ease of use, and safety. In recent years, pre-filled syringes have gained widespread use in the veterinary field due to their precise dosage control, excellent sealing properties, and ease of operation.

Application Range of Pre-filled Syringes

Pre-filled syringes are commonly used in the veterinary industry, particularly in the treatment of conditions such as mastitis in dairy cows, pet nutritional pastes, and oral pastes for horses and cattle. Their primary function is to accurately measure each dose of medication, reducing the chances of misuse or waste and ensuring that each dose is delivered to the targeted area. The advantage of this packaging format lies in its dual functionality: it serves as both a storage container for the drug and a syringe for its administration, making the use of medications more convenient and efficient.

Common specifications range from 5ml to 60ml to meet various dosage needs. Especially in the treatment of mastitis in dairy cows, the fine-tip pre-filled syringe, with its precisely designed nozzle, allows the medication to be accurately delivered to the affected area, minimizing operational errors and preventing drug wastage.

Sealing Requirements of Pre-filled Syringes

The sealing performance of a veterinary drug packaging container is essential to maintaining drug quality and efficacy. In pre-filled syringes, sealing is especially critical during transportation and storage. Exposure to external environments can lead to contamination or degradation of the drug. Therefore, choosing a syringe with excellent sealing capabilities not only ensures the safety of the drug but also enhances the stability of its efficacy.

To ensure sealing effectiveness, veterinary companies should consider the following key factors when selecting pre-filled syringes:

Sealing Components Standard:

The sealing performance of pre-filled syringes mainly depends on components like the piston and barrel. Although no specific industry standards have been released globally, the Chinese veterinary drug packaging industry standard YBB00112004-2015 and ISO 11040 series standards have served as guides for production and quality control. Choosing products that meet these standards is crucial for ensuring sealing effectiveness.

Piston and Plunger Fit:

The precise fit between the piston and plunger directly impacts the syringe’s sealing performance. During testing, the plunger and piston are connected and lubricated before filling the syringe with liquid to check for stability and sealing. This process eliminates air, ensuring that the syringe maintains its sealing performance during long-term use.

Multiple Experimental Validations:

To ensure sealing effectiveness under various environmental conditions, pre-filled syringes should undergo simulated tests such as accelerated aging tests and saturated saline tests. These experiments confirm the product’s stability under extreme conditions like high temperature and humidity.

Functions and Advantages of Pre-filled Syringes

Beyond ensuring sealing, the precise dosage control feature of pre-filled syringes is one of the reasons for their popularity. They are usually equipped with graduated markings and positioning rings, allowing users to slide the ring to the desired scale for accurate dosing. The simple design means operators don’t need to make complex calculations, allowing for precise medication delivery every time.

Additionally, pre-filled syringes come in both fine-tip and wide-tip designs, each serving different purposes. The wide-tip syringe ensures accurate dosage control due to the precise fit between the plunger and positioning ring, while the fine-tip design is more suitable for targeted drug administration to specific areas. For example, when treating mastitis in dairy cows, the fine-tip syringe can deliver medication precisely to the udder, reducing pain and stress during injection, which improves treatment effectiveness.

How Veterinary Companies Should Choose the Right Pre-filled Syringe

When selecting the appropriate pre-filled syringe, veterinary companies need to evaluate several factors:

Sealing Effectiveness:

Ensure the product meets international standards and has excellent sealing performance to prevent leakage and maintain the potency of the drug.

Dosage Accuracy:

Select syringes with clear scale markings and convenient dosage control mechanisms to ensure each administration is accurate.

Ease of Use:

Different veterinary drugs may require different types of pre-filled syringes. Companies should choose the appropriate specifications and designs based on the characteristics of the drug and its intended use.

Durability and Stability:

Test the syringes to ensure they remain stable and functional under various environmental conditions, avoiding issues like packaging damage or decreased drug efficacy due to temperature fluctuations during storage or transportation.

In veterinary pharmaceutical packaging, pre-filled syringes have become the preferred choice due to their precise dosage control, excellent sealing properties, and ease of use. By selecting packaging that meets stringent standards, veterinary companies can not only ensure the safety, effectiveness, and stability of their products but also enhance their market competitiveness and brand image, providing strong support for the company’s sustainable development.
