1. Product type: Y-type, straight type, safety type, retraction type, indentation.
2.Specification:10G-28G
3.OD:3.4mm-0.36mm
Key Advantages
Precision Back-Bevel Grinding
Tightly controlled bevel symmetry and edge sharpness between the primary bevel and back-bevels deliver ultra-low penetration resistance, significantly reducing the risk of vessel blowout and tissue trauma.
Ultraclean Washing & Degreasing
Multi-stage ultrasonic cleaning and Water for Injection (WFI) rinsing thoroughly eliminate processing lubricants and metallic microparticles, complying with medical-grade biosafety standards.
Zero-Burr & Non-Flared Tip Control
Micro-edges are clean and uniform, completely free of burrs, roll-overs, or tip eccentricity.
Ultra-Tight Tolerances & Superior Straightness
Strict tolerances for OD, ID, wall thickness, and straightness guarantee seamless, uniform assembly with catheter tubes and needle hubs.
Custom End Chamfering & Cut-to-Length
Customizable tube lengths, side slotting, proximal end chamfering, and sandblasting to customer prints.
Clinical Applications
– Continuous chemotherapy infusion
– Emergency fluid resuscitation
– Long-term antibiotic therapy
– Neonatal/Pediatric IV access
Quality Control(ISO 13485 QMS)
100% High-Speed Online Vision Inspection
Real-time automated inspection and rejection for tip geometry, bevel length, eccentricity, fishhooks, and edge burrs.
Micro-Cleanliness & Particulate Monitoring
Regular lot testing for surface residual oils and microscopic particulate levels.
Full-Dimension & Penetration Force Verification
Rigorous verification of OD, wall thickness tolerances, and lot penetration forces to ensure stable product consistency.

FAQs
Q: What is an indwelling needle?
A: An indwelling needle used for infusion or the like ordinarily has a double-needle structure composed of an outer needle and an inner needle. Upon its use, the indwelling needle is pierced into a blood vessel in a state where the inner needle is positioned in a lumen of the outer needle.
Q: What is the difference between an indwelling and a Foley?
A: A Foley catheter is a specific type of indwelling catheter; therefore, the terms are not mutually exclusive. Indwelling is the general category for any catheter left inside the bladder, while a Foley refers to a specific, popular design of indwelling catheter that uses an inflatable balloon to stay in place.
Q: What type of syringe is needed for an indwelling catheter removal?
A: Before you remove your catheter, gather all of the supplies you will need, including the syringe and an absorbent pad. You will be given the same-sized syringe that was used to inflate the balloon. Most syringes will be labelled 5 or 10 cc.
Q: How many types of indwelling catheters are there?
A: An indwelling catheter is a catheter that stays inside the body for a longer period, and there are two types. A urethral indwelling catheter is a catheter inserted through the urethra into the bladder, while a suprapubic indwelling catheter is inserted through the abdomen directly into the bladder.
