News & Information

In healthcare facilities, the effective management of patient fluids is a standard requirement for maintaining environmental hygiene and preventing skin complications. An underpad is a disposable, multi-layered absorbent sheet designed to protect medical furniture, such as hospital beds, examination tables, and wheelchairs, from liquid damage. Jianda Medical manufactures medical-grade underpads that provide reliable absorption and leak prevention for institutions managing high-volume patient care.

Multi-Layer Material Construction

The technical performance of the Jianda Medical underpad is determined by its specific structural layers. Each layer serves a distinct functional purpose to manage moisture effectively:

1. Hydrophilic Non-Woven Top Sheet

The uppermost layer, which comes into direct contact with the patient, is made of a soft, hydrophilic non-woven fabric. This material allows liquids to pass through rapidly into the absorbent core below. It is engineered to remain dry on the surface, which minimizes friction and reduces the risk of moisture-associated skin damage (MASD) for the patient.

2. Absorbent Core with SAP

The middle layer is the primary functional component. It consists of a blend of virgin fluff pulp and Super Absorbent Polymer (SAP).

• Fluff Pulp: Provides the structural volume necessary to distribute the liquid quickly across the pad.

• SAP: Chemically binds the liquid and converts it into a gel. This prevents the fluid from being squeezed back to the surface when the patient applies physical pressure to the pad.

3. Waterproof PE Backsheet

The bottom layer is manufactured from Polyethylene (PE) film. This layer is entirely impermeable to liquids, ensuring that no moisture reaches the mattress or upholstery below. The PE film is often designed with a slight texture to increase friction and prevent the pad from sliding during use.

Technical Design Features

To ensure operational reliability in clinical settings, Jianda Medical integrates several specific design elements into its underpad production:

• Diamond Embossing: The surface of the absorbent core features a diamond-pressed pattern. This physical structure channels liquid evenly across the pad, preventing localized saturation and maximizing the total absorption capacity.

• Heat-Sealed Edges: All four sides of the underpad are securely heat-sealed. This prevents the internal fluff pulp and SAP from escaping and blocks liquid from leaking out of the sides of the pad.

• Variable Specifications: The underpads are produced in multiple standard sizes (such as 60x60cm and 60x90cm) and different SAP concentrations to meet varying clinical requirements, from light diagnostic use to heavy incontinence management.

Primary Institutional Applications

The Jianda Medical underpad is utilized across a wide range of medical and care departments:

• Geriatric and Nursing Homes: Used daily to manage urinary and fecal incontinence, protecting bed linens and reducing the frequency of complete bed changes.

• Surgical Wards: Placed under patients during post-operative recovery to absorb wound exudate or minor bleeding.

• Maternity Departments: Utilized during and after delivery to manage amniotic fluid and blood output.

• Outpatient Clinics: Employed as a protective barrier on examination tables during minor procedures or fluid irrigation.

Operational Advantages for Healthcare Procurement

For hospitals and long-term care facilities, standardizing the use of high-quality underpads offers measurable logistical benefits:

• Cost Efficiency: Utilizing a high-absorbency pad reduces the need for multiple pad changes per patient, lowering overall consumable usage.

• Labor Reduction: Effective underpads decrease the volume of soiled hospital linens, directly reducing the workload and resource consumption of the facility's laundry department.

• Quality Assurance: Jianda Medical operates under ISO 13485 quality management systems, ensuring that every batch of underpads meets strict medical manufacturing standards for hygiene and performance.

Conclusion

An underpad is an essential technical tool for managing clinical fluids and maintaining facility hygiene. By combining a rapid-absorption non-woven surface with a high-capacity SAP core and a waterproof backing, Jianda Medical provides a reliable barrier solution. For healthcare procurement departments, selecting standardized underpads based on these objective material specifications is a necessary step to optimize patient care and facility resources.
