Product Details

1. Product Positioning

Designed specifically for maternal-infant care, individuals with incontinence, post-operative patients, and medical care scenarios. It addresses three core pain points: leakage protection, skin comfort, and care convenience. It replaces traditional cotton pads that require repeated washing, reducing care workload and improving the quality of life for users.

2. Core Structure (Five-Layer Composite Protection System)

  1. Surface Layer: Skin-Friendly Diversion Layer

Adopts 30g/m² soft non-woven fabric (or dry mesh fabric), with a diamond-patterned surface treatment to increase liquid contact area while accelerating diversion, preventing local fluid accumulation. The material is as soft as cotton with a low friction coefficient, reducing skin friction damage to infants’ delicate skin and bedridden elderly.
  1. Second Layer: Rapid Penetration & Diffusion Layer

A fluffy non-woven interlayer that quickly channels liquid to the absorbent layer through fiber gaps, preventing residual moisture on the surface and enhancing instant dryness.
  1. Third Layer: Core Absorbent Layer

Filled with a composite structure of high-magnification Super Absorbent Polymer (SAP) + fluff pulp. The SAP has a water absorption rate of 300-500 times (capable of absorbing 300 times its own weight in normal saline). After absorbing water, it forms a gel-like state without rewetting or caking, and can handle 2-3 liquid penetration events in a single use.
  1. Fourth Layer: Leak-Proof Barrier Layer

A 0.02mm thickened PE waterproof film treated with anti-puncture technology to effectively block liquid penetration into bed linens. The film has over 500 breathable microholes per m², balancing waterproofness and breathability to avoid stuffiness.
  1. Bottom Layer: Anti-Slip Fixing Layer

Dot-shaped anti-slip adhesive on the four corners (or full width) with moderate adhesion. It stays in place when laid on mattresses/sheets and remains stable even when the user turns over or moves.

3. Core Function Highlights

  1. Long-Lasting Dry Protection

Within 5 seconds of liquid contacting the surface layer, the process of diversion-absorption-liquid locking is completed. The residual humidity on the surface is <15%, and the skin remains dry even after long-term use (6-8 hours), reducing the risk of diaper rash, eczema, and pressure sores.
  1. All-Dimensional Leak-Proof

3cm high elastic 3D side guards (standard for adult/bed models) + bottom waterproof film + anti-slip adhesive form triple protection against side leakage, bottom leakage, and displacement, eliminating leakage risks during nighttime use or when turning over.
  1. Safe & Skin-Friendly Certification

Raw materials meet OEKO-TEX® 100 Class 1 certification (infant safety standard), free of fluorescent agents, formaldehyde, and heavy metals. The pH value ranges from 5.5 to 6.5 (close to the weak acid environment of human skin), making it safe for sensitive skin, newborns, and post-operative fragile skin.

5. Ease of Use

  1. Individual Packaging: Each piece is individually sealed to prevent dust and moisture, easy to carry for outings or hospital accompany, and can be taken as needed.

  1. Easy Replacement Design: Pre-cut easy-tear edges allow removal by gently peeling off the adhesive, no need to remove bed linens. A single replacement takes <1 minute, saving 80% of the time compared to washing traditional cotton pads.

  1. Eco-Friendly Disposal: The main material is biodegradable (for some models). After use, it can be discarded according to household waste regulations without environmental pollution.

6. Quality Assurance

  • The production workshop meets GMP medical-grade cleanliness standards. Each batch of products undergoes total bacterial colony testing (≤200cfu/g) and leakage testing (no leakage after 200ml liquid is left standing for 2 hours).

  • 7-day no-reason return and exchange service is supported (for unopened products). Post-sales care guidance is provided to address users’ practical usage questions.
