Product Description:

Negative pressure drainage bag is a medical device used to treat exudate around wounds or surgical incisions, promoting the healing of the bottom of the wound and the discharge of exudate through the principle of negative pressure.

The negative pressure drainage system usually consists of the following components:

1. Drainage bag: A negative pressure drainage bag is a sealed bag connected to a negative pressure pump or negative pressure suction device inside. The drainage bag is usually transparent, making it easy for medical staff to observe the amount and texture of liquid inside the bag.

2. Drainage tube: The drainage tube connects the drainage bag to the wound or surgical incision, used to drain the exudate from the wound into the drainage bag.

3. Negative pressure pump or suction device: The negative pressure pump or suction device generates negative pressure and draws the exudate from the drainage tube into the drainage bag. These devices typically have different settings that can adjust the intensity and frequency of negative pressure.

The function of a negative pressure drainage bag is to help clear the exudate around the wound through the force of negative pressure, reduce the time that the exudate stays on the surface of the wound, promote healing at the bottom of the wound, and reduce the risk of infection. Meanwhile, negative pressure drainage can also promote blood circulation and tissue repair, accelerating the wound healing process.

Negative pressure drainage bags are widely used in various types of postoperative wound management, wound treatment, and chronic ulcer situations, providing effective treatment and rehabilitation plans for patients.
