## Common ground
All options are medical devices used for collecting and measuring urine, typically in clinical or home care settings.
## Options at a glance
**3926.90 – Non-invasive sterile collection**
- **Defining trait:** Designed primarily for sterile urine collection without continuous measurement; focuses on containment and hygiene.
- **Typical examples:** Standard bedside drainage bags with anti-reflux valves, used during hospital stays.
- **Best fit when:** The main purpose is safe, hygienic storage of urine over time, not real-time monitoring.
**9026.10 – Sterile measuring meter**
- **Defining trait:** Specifically engineered for accurate measurement of urine volume or flow rate; includes built-in calibration or readout features.
- **Typical examples:** Digital urine meters used in intensive care units to track hourly output, or bedside devices with graduated markings.
- **Best fit when:** Precise quantification of urine output is required (e.g., for kidney function assessment).
## Key differences
| Feature | 3926.90 – Collection | 9026.10 – Measuring |
|-----------------------|----------------------------|------------------------------|
| Primary function | Storage and containment | Measurement and monitoring |
| Accuracy focus | Low (no measurement) | High (calibrated output) |
| Use case | General drainage | Clinical monitoring |
## How to choose
- Does the device need to measure urine volume or flow? → 9026.10
- Is it used only for storing urine without tracking? → 3926.90
## Overlaps & pitfalls
Both are sterile, PVC-based, and used in medical settings. A bag may have measurement markings but still fall under 3926.90 if measurement is not its primary function. The key distinction lies in **intended purpose**: if measuring urine is central, use 9026.10; otherwise, 3926.90 applies. Do not assume that any marking implies measurement capability—only devices designed for accurate flow/level checking qualify under 9026.10
