For individuals using Continuous Glucose Monitoring (CGM) systems, ensuring the sensor remains stable and comfortable on the skin is fundamental to effective monitoring. The CGM patch (also known as a fixation patch or protective overlay) is an auxiliary product specifically designed for this purpose.
Working Principle of the CGM Patch
The core function of a CGM patch is to serve as a reliable, comfortable, and protective fixation system. Its working principle can be understood through the following table:

Functional Description |
|
Secure Anchoring Base |
The CGM sensor itself comes with a small medical adhesive tape, but its adhesion might be insufficient against challenges like movement, sweat, or prolonged wear. The patch provides a larger base with superior adhesion, firmly securing the sensor's edges and body to the skin to prevent lifting or complete detachment. |
|
Environmental Resistance |
High-quality patches are made from waterproof or highly sweat-resistant materials, capable of resisting moisture from daily showers, swimming, or intense exercise. This protective barrier safeguards the sensor's own adhesive, ensuring stability even in humid conditions. |
|
Enhanced Comfort |
Patches are typically made from soft, breathable, medical-grade materials (such as elastic fabric, hydrocolloid, etc.). This layer isolates the sensor's hard edges from direct skin contact, reducing friction and pressure. Simultaneously, its breathability prevents skin discomfort or allergies caused by heat and moisture buildup. |
Core Patient Benefits of CGM Patches
Based on the principles above, a high-quality CGM patch offers patients significant multifaceted benefits:
1. Improved Data Continuity & Management Efficacy:
The patch significantly reduces the risk of monitoring interruptions caused by sensor detachment. This means patients obtain more continuous, complete dynamic glucose data, enabling them and their doctors to make more precise treatment decisions, optimizing insulin dosages and dietary plans.
2. Enhanced Lifestyle Freedom & Confidence:
Reinforced by the patch, patients can participate more confidently in various life activities—whether daily showers, swimming, running, or gym workouts—without excessive worry about accidental sensor detachment. This greatly enhances quality of life and adherence to diabetes management routines.
3. Improved Wear Comfort & Skin Health:
The soft, breathable design of the patch effectively helps prevent and reduce skin issues such as redness, itching, dermatitis, or allergic reactions caused by long-term wear or repeated removal. This is particularly crucial for children and patients with sensitive skin.
The Ceeport CGM Patch offers the following standout advantages, precisely meeting the needs of patients in the US market:
1. User-Friendly Three-Segment Backing Design:
The unique side-wing design allows for easy, one-handed application, solving the problem of misalignment during self-application.
It effectively prevents finger contact with the adhesive, preserving initial tackiness and ensuring a "get it right the first time" experience.
2. Exceptional Comfort and Secure Hold:
The highly elastic medical fabric conforms naturally to body contours (e.g., arm, abdomen), providing a restriction-free secure fit even during vigorous activity.
Combined with a strong yet gentle, hypoallergenic acrylic adhesive, it achieves a balance between "secure" and "gentle," ensuring it stays in place during exercise and sweating while being suitable for long-term use on sensitive skin and by children.
3. Considerate Skin Protection Design:
The center non-adhesive zone and central nonwoven protective layer are key features. They prevent the patch from adhering to the sensor itself, avoiding accidental dislodgement of the expensive sensor during patch changes. Concurrently, this soft barrier reduces friction between the sensor and the skin, further lowering the risk of irritation.
4. Broad Compatibility and Professionalism:
The product is specifically designed for mainstream US sensor models like the Dexcom G7 and Free Style Libre 2/3, with precise cutouts that do not interfere with signal transmission or detection.
The waterproof and breathable (characteristic) allows patients peace of mind during daily water exposure while maintaining skin dryness and comfort.
Summary
As an important component of continuous glucose monitoring systems, the technological innovation and performance optimization of CGM patches are directly related to patients' monitoring experience and management outcomes. By understanding their working principles and technical characteristics, healthcare professionals and patients can make more informed choices, thereby achieving a more accurate and comfortable blood glucose management experience.
