Sterile Negative Pressure Drainage Device for Surgical Postoperative Drainage

1.Intended Use:

This closed wound drainage system is intended for closed drainage of exudate, blood and effusion from surgical incisions and soft tissue wounds. It is applicable to postoperative drainage in various surgical departments to eliminate wound dead space, reduce local effusion and hematoma, and assist wound healing.

2.Product Structure:

The device consists of drainage tube, connecting tube, one-way valve, negative pressure reservoir and visual pressure indicator. The whole set is integrally assembled and sterile for single use.

3.Working Principle:

The pre-evacuated negative pressure reservoir forms stable subatmospheric pressure. Through the pressure difference, the system continuously and actively drains wound effusion and gas. The one-way valve structure prevents backflow of drainage fluid and external bacterial contamination, realizing closed and safe wound drainage.

4.Product Advantages：

”This product provides stable and sustainable negative pressure drainage without external negative pressure equipment. The fully closed structure effectively reduces surgical site infection. The transparent graduated reservoir enables accurate observation and recording of drainage volume and properties. The soft biocompatible catheter reduces tissue stimulation and is conducive to postoperative wound recovery.

5.Technical Parameters：

1. Capacity: 200 mL / 400 mL / 600 mL

2. Nominal negative pressure: -60 mmHg ~ -100 mmHg

3. Sterilization method: Ethylene oxide (EO) sterilization

4. Material: Medical grade silicone, medical PVC

6.Contraindications
