Managing kidney stone collection can be a stressful process, which is why having the right tool is essential for comfort, accuracy, and convenience. Designed to provide reliable stone capture while remaining discreet, compact, and easy to carry. Whether used at home, in a clinic, or while traveling, it combines medical-grade materials with a space-saving design to support patients and caregivers throughout the recovery process. The funnel is crafted from soft, flexible silicone that adapts easily to handling, making specimen collection more comfortable than with rigid plastic alternatives. The smooth surface is gentle to use and simple to grip, reducing stress during collection. A fine stainless steel mesh screen ensures precise filtration, effectively capturing kidney stones and fragments for accurate analysis. Even small particles are securely retained, enabling healthcare providers to evaluate treatment progress more accurately. A key feature of this device is its collapsible, flat-folding design. When not in use, the funnel compresses into a compact shape that is designed to be 4 inches by 4 inches or roughly the size of a wallet (note: this is too large to fit inside a wallet). Being smaller than a typical rigid plastic kidney stone collector, it fits discreetly into a pocket, handbag, or drawer. This makes it practical for patients who need a portable solution for stone collection without drawing unnecessary attention. Once expanded, it provides a dependable size and structure for smooth and efficient urine straining. The washable and reusable construction offers both hygiene and long-term value. The silicone and stainless steel materials resist odors, staining, and bacterial buildup. After each use, the funnel can be cleaned easily by hand or in the dishwasher, ensuring proper sanitization and readiness for repeated use. This kidney stone collector funnel delivers an effective, practical, and patient-focused solution for discreet stone collection in everyday life.
