Q1: Is the 21G interventional needle more traumatic than 20G because it's thicker?
A1: The outer diameter of 21G is about 0.8mm, a medium - sized specification, with less trauma than thicker 18G; moreover, the needle tip is precisely ground, with weak tissue tearing feeling during puncture. With the stable grip of the wing - type hub, it can control the trauma at a low level while ensuring sampling/drainage efficiency.
Q2: The hub is green, is there any special meaning? Or can the color be customized?
A2: The green hub is mainly for visual differentiation of specifications (some manufacturers use colors to identify G numbers), and the hub color can also be customized (such as blue, yellow, etc.) according to needs; but functionally, it does not affect sealing and operation. Just provide the color number or sample.
Q3: Can this needle be used with our existing syringes?
A3: Yes. The needle body uses a standard Luer Lock interface. As long as your syringe/catheter is Luer Lock - compatible, it can connect tightly without leakage risk; if your device has a special interface, you can also provide drawings, and we will customize the matching hub.
Q4: How to choose between disposable and repeatable sterilization versions?
A4: If it is for high - frequency use in outpatient/emergency departments, it is recommended to choose the disposable version (EO sterilized, ready to use) to avoid cross - infection; if it is for unified management by the hospital sterilization supply room, the repeatable sterilization version (134℃ autoclaved) can be selected, with lower long - term use cost.
Q5: Is the needle body easy to bend? What should be paid attention to during operation?
A5: The medical - grade stainless steel needle body has good rigidity, and it is not easy to bend under normal puncture (non - violent torsion); it is recommended to keep the needle body perpendicular to the skin during operation, and use the anti - slip texture of the wing - type hub to stabilize the force, avoiding needle body deformation caused by lateral force.
