Negative Pressure Wound Drainage Device A/400ML

The Negative Pressure Wound Drainage Device is a sterile, disposable closed wound drainage medical device specially developed for postoperative and traumatic wound management. Different from the bulky electric NPWT therapy system, this portable negative pressure drainage device adopts a physical self-suction negative pressure design, requiring no external power supply, vacuum pump or battery, which enables convenient and safe negative pressure drainage for various wounds in general wards, outpatient departments and home care scenarios.

After professional sterile placement, the device forms stable and continuous micro-negative pressure inside the wound cavity. It can effectively and continuously drain wound exudate, hemorrhagic fluid, inflammatory secretions and necrotic tissue residues, thoroughly eliminate fluid accumulation in the wound bed, and avoid hematoma and effusion-induced wound swelling, infection and adhesion. By maintaining a clean, moist and sterile closed wound environment, the device significantly improves local microcirculation, promotes granulation tissue hyperplasia and epithelial growth, and greatly shortens the overall wound healing cycle.

The whole product adopts medical-grade soft PVC and high-flexibility drainage tube materials, which are non-toxic, non-irritating, highly biocompatible and compliant with medical sterile standards. The built-in one-way anti-backflow structure effectively prevents the backflow of drained fluid and external bacterial contamination, ensuring zero reverse infection during the entire drainage process. The integrated anti-blocking and smooth flow channel design avoids pipeline blockage caused by tissue residues and viscous exudate, ensuring long-term stable drainage effect.

This disposable negative pressure wound drainage device features lightweight structure, easy operation and simple dressing replacement. It reduces the frequency of wound dressing changes, lowers the workload of medical staff, and minimizes secondary damage and pain caused by frequent wound exposure. The closed drainage mode also reduces the risk of cross-infection in hospital and effectively improves the clinical safety of wound care.

Widely applicable for general surgical incisions, orthopedic postoperative wounds, trauma lacerations, soft tissue injury wounds, burn and scald wounds, chronic refractory wounds and various postoperative cavity drainage. It is an essential basic consumable for clinical closed negative pressure wound treatment.
