Stopcock

High-Performance Stopcock with Airless Rotator Technology

This precision-engineered stopcock represents a significant advancement in fluid control technology, designed to address critical needs in medical and laboratory environments where reliability, clarity, and ease of use are paramount. Integrating airless rotator technology and a clear inner lumen with an intuitive shark fin handle, it provides unparalleled control for directional fluid management, minimizes the risk of air embolism, and enhances procedural efficiency.

1. Patented Airless Rotator Technology

The core innovation of this stopcock lies in its proprietary mechanism designed to virtually eliminate air bubbles during operation, a critical factor in many sensitive applications.

• Bubble-Free Transition: The precision-engineered rotator creates a seamless, laminar pathway when switching between ports, preventing the introduction and entrapment of air within the fluid column.

• Enhanced Patient Safety: In clinical settings such as intravenous therapy, contrast media delivery, or arterial line management, this feature significantly reduces the potential for air embolism, contributing to improved patient safety protocols.

• Consistent Fluid Integrity: For laboratory and diagnostic procedures, it ensures uncontaminated sample transfer and precise reagent delivery without gaseous interference, safeguarding the accuracy of results.

2. Clear Inner Lumen & Visual Flow Confirmation

Full visual access to the fluid pathway is integral to the design, providing immediate confirmation of flow status and fluid characteristics.

• Complete Transparency: The clear polymer or glass construction of the inner lumen allows for unobstructed visualization of fluid type, color, and flow, enabling quick identification of blood flashback, contrast media presence, or potential clots.

• Real-Time Operational Feedback: Operators can instantly verify the success of port switching and confirm that the fluid path is open and unobstructed, reducing operational errors.

• Material Compatibility: The lumen material is selected for clarity and chemical resistance, compatible with a wide range of medications, contrast agents, and biological fluids without risk of clouding or degradation.

3. Ergonomic Shark Fin Handle Design

Control and reliability are maximized through an intuitive and secure handle design, engineered for use in high-pressure or sterile environments.

• Positive Tactile Grip: The distinctive shark fin shape provides a secure, non-slip grip even with gloved hands or in wet conditions, allowing for precise rotational control with minimal effort.

• Single-Handed Operation: The extended fin lever enables easy single-handed adjustment, freeing the clinician's other hand for other critical tasks. The design offers definitive "clicks" or positive stops at each port position for unambiguous confirmation of the selected pathway.

• Durable and Sterilizable: Constructed from robust medical-grade materials, the stopcock is built to withstand repeated use and is compatible with standard sterilization methods (e.g., autoclave, ETO, gamma radiation), ensuring long-term reliability.

By combining these advanced features, this stopcock delivers superior performance, safety, and user confidence for demanding fluid control applications across medical and scientific disciplines.
