Behind every accurate Continuous Glucose Monitoring (CGM) reading lies a tiny yet critical core component — the CGM guilding insertion needle.

Often misunderstood, this professional medical accessory acts only as a temporary guiding tool for sensor implantation. It never remains inside the human body. Its core mission is to precisely deliver flexible CGM sensors into subcutaneous interstitial fluid, laying a solid foundation for stable, long-term glucose data monitoring.

Premium Material & Precision Engineering for Medical-grade Safety

At Atom Tech, we prioritize safety, comfort and durability in every detail of our CGM insertion needles. 

Our needles are crafted from medical-grade stainless steel SUS304R-H, featuring exceptional biocompatibility, corrosion resistance and structural stability to meet strict global medical device standards.

To minimize insertion trauma and achieve near-painless experience, we adopt high-precision microscopic grinding technology for the needle tip. The optimized U-shaped grooved guide structure perfectly locks and guides flexible sensors during implantation, ensuring smooth penetration and clean needle retraction without displacement.

With ultra-fine specifications outer diameter (0.5mm–0.6mm) and customized lengths of 20mm–28mm, our insertion needles fit most mainstream CGM wearable devices. They achieve precise subcutaneous implantation, effectively reducing user discomfort and improving overall wearing experience.

Intelligent Working Mechanism, Stable & Efficient Implantation

Paired with automatic CGM applicators, Atom’s CGM insertion needles adopt a spring-triggered instant implantation mechanism.

In one second, the needle guides the sensor to reach the optimal subcutaneous position, then automatically retracts and hides instantly. Only the soft, flexible sensor filament remains under the skin for continuous, real-time glucose tracking.

This one-touch automatic operation eliminates manual insertion errors, delivers consistent implantation depth and position, and greatly improves the yield rate and usability of CGM equipment — ideal for mass production and consumer-grade wearable medical devices.

Strict Medical Specifications & Standardized Usage

As disposable sterile medical devices, our CGM insertion needles follow strict industry norms:

✅ 100% single-use only: Effectively avoid cross-infection, needle tip curling and broken needle risks

✅ Full sterile packaging: Guarantee medical safety for long-term wearable monitoring
