News & Information

In healthcare facilities and home care settings, maintaining skin integrity and surface hygiene is a primary operational requirement. A medical underpad is a multi-layered absorbent sheet designed to protect beds, chairs, and other surfaces from fluid damage caused by incontinence, surgical procedures, or wound drainage. Understanding the technical specifications of these products is essential for selecting the correct solution for clinical needs.

Material Composition and Layered Structure

The effectiveness of a Jianda Medical underpad is determined by its multi-layer construction. Each layer is engineered to fulfill a specific functional role in moisture management:

• Top Sheet (Hydrophilic Non-Woven Fabric): The surface in contact with the patient is made of soft non-woven fabric. This material allows fluids to pass through quickly to the absorbent core while remaining dry to the touch to prevent skin maceration.

• Absorbent Core (Fluff Pulp and SAP): The core consists of virgin fluff pulp mixed with Super Absorbent Polymer (SAP). The fluff pulp distributes the liquid, while the SAP chemically locks the moisture into a gel, preventing "rewet" even under body pressure.

• Back Sheet (Polyethylene Film): The bottom layer is a waterproof PE film. This impermeable barrier prevents any fluid from leaking through to the mattress or upholstery, ensuring the protected surface remains dry.

Key Technical Features for Enhanced Protection

To ensure reliable performance in high-demand medical environments, several design features are integrated into the underpad:

Diamond Embossing

The absorbent core features a diamond-shaped embossed pattern. This design facilitates the rapid and even distribution of liquid across the entire surface of the core, preventing local saturation and increasing the effective absorption capacity.

Heat-Sealed Edges

All four sides of the underpad are heat-sealed. This construction prevents the internal absorbent materials from shifting or leaking out, ensuring that all fluids are contained within the boundaries of the pad.

Non-Slip Backing

The PE back sheet is designed with a texture that minimizes sliding on bed linens or chairs. This helps keep the pad in the correct position as the patient moves, reducing the need for frequent repositioning by clinical staff.

Primary Clinical Applications

Underpads are utilized across various medical departments to manage fluid-related risks:

• Incontinence Management: Used in geriatric and nursing wards to protect bedding and reduce the risk of moisture-associated skin damage.

• Post-Operative Care: Placed under patients to manage wound exudate or drainage following surgical procedures.

• Maternity and Neonatal Care: Employed during and after delivery to manage blood and amniotic fluid.

• General Diagnostics: Used on examination tables to maintain a sterile barrier and protect equipment from liquid splashes.

Selection Criteria for Procurement Professionals

When sourcing from underpad suppliers, procurement departments should evaluate several objective factors to ensure product quality:

1. Absorption Capacity: The total volume of fluid the pad can hold relative to its size (e.g., 60x60cm or 60x90cm).

2. SAP Concentration: Higher SAP content generally indicates a superior ability to lock in moisture and control odors.

3. Sterility Options: Depending on the application, underpads may be required in sterile or non-sterile formats.

4. Regulatory Compliance: Ensure the manufacturer adheres to ISO 13485 quality management systems and that products meet CE or other relevant international standards.

Conclusion

A medical underpad is a technical solution for fluid containment that relies on precise material engineering. By utilizing high-quality SAP and fluid-resistant backing, Jianda Medical provides a reliable tool for infection control and surface protection. For healthcare facilities, choosing underpads that meet these structural and performance standards is a critical step in maintaining professional hygiene and patient safety.
