Indwelling Needle (IV Catheter Cannula): Advanced Vascular Access for Sustained Therapy Delivery.
Indwelling Needle Clinical Purpose
Our indwelling needles provide secure, long-term vascular access for intravenous fluid administration, medication delivery, and blood sampling. Engineered for indwelling durations up to 96 hours, they minimize repeated punctures in critical care, oncology, and pediatric settings.
Product Specification:
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 Puncture Technology
– Laser-honed triple-bevel tip (14° grind angle) enables smooth tissue penetration with 30% less insertion force vs. standard needles.
– Ultra-sharp cutting edge reduces vessel trauma and patient discomfort (validated by VAS pain scores ≤2/10).
Enhanced Safety & Visibility
– Radiopaque X-ray detectable wings and catheter line for position confirmation under fluoroscopy.
– Safety-engineered versions feature:
– Automatic needle retraction upon withdrawal (retraction type)
– Blunt cannula activation (safety type)
– One-handed activation (OSHA-compliant)
Material Innovation
– Cannula: Medical-grade 316L stainless steel (OD: 0.36–3.4mm) with electropolished interior
– Catheter: DEHP-free polyurethane (thin-wall design maintains flow rates up to 300mL/min)
– Hub: CT/MRI-compatible polycarbonate with Luer-Lock
Clinical Applications
– Continuous chemotherapy infusion
– Emergency fluid resuscitation
– Long-term antibiotic therapy
– Neonatal/Pediatric IV access
Quality Compliance
– Sterile EO gamma irradiation | ISO 10555-5 | FDA 510(k) K230755
– Color-coded hubs for gauge identification
– Customization: Extension tube length (15–50cm), passive safety clips

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.
