Venous Cannula
This product is intended for use in extracorporeal circulation during open‑heart surgery.
Straight Tip: This product features a gradually tapered tip with multiple side holes, and the entire tubing is reinforced with stainless steel wire. It is easy to bend yet resistant to kinking.
Elbow: This product features a pre‑formed 90° bend, making it suitable for superior and inferior vena cava cannulation. It is also equipped with depth markings to ensure precise catheter placement.
Metal elbow: This product features a 90° metal right-angle bend at the tip. The tip has a beveled surface, thin walls, and tapers gradually to facilitate insertion.
Bipolar (circular): The bipolar catheter design effectively drains the porous segment within the atrium, while the elliptical shaft enables the required... to be achieved in a smaller footprint.
Arterial Cannula
This product is intended for use in extracorporeal circulation during open‑heart surgery.
Straight‑tip reinforcement: This product features a stainless‑steel wire‑reinforced tube wall, with a beveled tip for easy insertion. The tip is equipped with a stopper and includes a blue suture ring that can…
Straight tip, wire-free: This product features a stainless steel‑free tube wall and a beveled tip for easy insertion, along with a blue suture ring for precise placement...
Elbow Reinforcement: The product features a gradually tapered tip, and the entire tubing is reinforced with stainless steel wire. It is easy to bend yet resistant to kinking.
Aortic cannulation (pediatric): spherical tip, suitable for infants and young children. Indicated for aortic cannulation in neonates and low-birth-weight infants.
Femoral Venous Cannula
This product is intended for surgical suction use.
Unipolar core‑type: The product is a slender, integral tubular conduit reinforced with stainless steel wire and featuring a hollow central lumen that can accommodate a guidewire. It is inserted via the femoral vein into the inferior vena cava or the right atrium. Primarily used for venous blood drainage in minimally invasive cardiac procedures. For ECMO venous blood drainage, it can be placed through percutaneous puncture.
Bipolar lead core: The tubing is reinforced with stainless steel wire, and the bipolar design effectively meets the requirements for cardiac blood drainage. It efficiently saves space, with the distal side port entering the superior vena cava to drain its blood and the proximal side port entering the inferior vena cava to drain its blood.
Femoral Arterial Cannula
This product is intended for surgical suction use.
Unipolar core‑type sheath: features 3–4 rows of lateral holes on the lumen side, which helps reduce pump pressure under the same conditions. The core‑type sheath is guidewire‑guided for insertion and is suitable for femoral or axillary artery cannulation. Its graduated shaft facilitates accurate assessment of insertion depth. It can also be used in minimally invasive cardiac procedures, such as jugular venous puncture and drainage.
Single‑stage core‑guided lock / dual‑lumen: features two lateral ports at the catheter tip. Core‑guided lumen: can be advanced over a guidewire for insertion. Suitable for femoral and axillary artery cannulation. The catheter wall is marked with graduations to facilitate accurate depth control. Core: has a relatively sharp tip angle and excellent wall‑contact properties, making puncture and catheter placement easier.
Disposable Suction Tube
This product is intended for surgical suction use.
Suction Tube (Type A): This product features a tapered, pointed tip with multiple lateral holes, making it suitable for various surgical suction applications and resistant to blockage.
Suction catheter (Type B, with or without a wire core): Made of silicone rubber tubing and reinforced with a stainless steel wire core, it can be pre‑bent to a fixed angle. It features multiple side holes at the left ventricular tip and is not suitable for generating negative pressure.
Suction Tube (Type C, Stainless Steel): Features a comfortable handle and a grooved tip to enhance suction while minimizing tissue damage.
Central venous catheter: How should the insertion site be selected?
1. How should the insertion site for a central venous catheter be selected? Currently, multiple guidelines and the Chinese Expert Consensus on Vascular Access for Hemodialysis recommend the following order of catheterization sites: right internal jugular vein, left internal jugular vein, right femoral vein, left femoral vein, and subclavian vein.
