NPWT Transparent Sterile Polyurethane Surgical Incise Film For Surgery Operation
The main component is polyurethane (PU). This material has good biocompatibility, is less irritating to human tissue, and can reduce the probability of allergies and other adverse reactions. At the same time, it has excellent flexibility and elasticity, can adapt to the contours and activities of different parts of the body, and will not easily fall off or break due to limb movements.
It is generally composed of a multi-layer structure. The outermost layer is a waterproof and breathable PU film that can prevent external moisture and bacteria from invading, while allowing water vapor from the wound to penetrate and keep the wound relatively dry. The middle layer may contain adsorbent materials that can absorb wound exudate and prevent exudate accumulation from affecting wound healing. The inner layer is usually a hydrophilic coating or film that is in direct contact with the wound, which can fit the wound surface, reduce friction on the wound, and promote wound healing.
| Clinical application | |
| Surgical wounds: | commonly used for wound drainage after various surgical operations, such as abdominal surgery, cardiothoracic surgery, orthopedic surgery, etc. It can effectively prevent postoperative wound infection, promote wound healing, reduce the number of dressing changes, and reduce the pain of patients and the workload of medical staff. |
| Chronic wounds: | For some chronic wounds that are difficult to heal, such as diabetic foot ulcers and pressure sores, the negative pressure drainage PU surgical membrane can remove necrotic tissue and secretions in the wound through continuous negative pressure suction, stimulate the growth of granulation tissue, and accelerate wound healing. |
| Burn wounds: | In burn treatment, it can be used to cover the burn wound, play a role in protecting the wound, reducing the chance of infection, and promoting wound healing. At the same time, negative pressure drainage helps to remove exudate and toxins from the wound and reduce local inflammatory reactions. |
