Medical Silicone Negative Pressure Drainage Bulb for Wound Exudate

Silicone Negative Pressure Drainage Bulb Product Description​

This product is a ​​single-use sterile drainage system​​ composed of ​​medical-grade silicone​​ and ​​polymer PVC components​​. It generates negative pressure through manual compression for closed drainage and collection of postoperative wound exudate, blood, and body cavity fluids. Its core advantage lies in ​​self-controlled physical negative pressure​​, requiring no external power device, ensuring safe and convenient operation for multi-scenario clinical drainage needs.




​Enhanced Core Features​

​Feature​​Detailed Specifications​
