Our control ring medical syringe is a precision-engineered delivery tool designed for interventional radiology, cardiology, angiography and clinical liquid administration, combining ergonomic design with reliable medical-grade construction to meet strict hospital procedural standards. Crafted with a transparent polycarbonate barrel, this syringe features clear, permanent volume graduation markings from 0 to 12ml, enabling clinicians to read fluid dosage at a glance with zero visual distortion. The barrel resists chemical corrosion from contrast media, medical reagents and injectable liquids, supporting repeated precise aspiration and injection without material degradation. A secure luer lock connector with a red sealing gasket ensures leak-free attachment to catheters, stopcocks and medical tubing, eliminating fluid waste and contamination risks during delicate vascular procedures.

Its standout dual-ring grip system redefines operational comfort and dosage control. Two integrated finger rings at the barrel rear and a large push ring on the plunger allow physicians to hold and manipulate the syringe with one hand effortlessly. This design delivers ultra-fine flow regulation-critical for slow, steady contrast injection in angiograms-reducing hand fatigue during lengthy surgeries and minimizing dosage errors caused by slippery single-handle syringes. The white plunger rod is fitted with a black silicone piston that maintains consistent airtight sealing, ensuring smooth, jerky-free movement throughout the full volume range.

Manufactured under ISO 13485 medical quality protocols, all raw materials are biocompatible, non-toxic and latex-free, compatible with sterile clinical environments. Disposable and reusable specifications are both available to fit hospital cost management needs. Widely adopted in cardiac catheter labs, radiology departments and outpatient injection clinics, this control ring syringe enhances procedural safety, boosts injection accuracy and streamlines clinical workflows. Compared to standard syringes, its ergonomic ring structure drastically improves operator stability, making it an essential auxiliary device for minimally invasive interventional treatments and precise liquid dosing tasks.
