DEDICATED DRESSING STRUCTURE FOR SEALED DRAINAGE UNDER NEGATIVE PRESSURE

摘要

A dedicated dressing structure for sealed drainage under negative pressure comprising a drainage tube (1) and a medical-grade foam material (2), characterized in that the drainage tube is divided into an external connection tube (3) and an internal tube (4), and wherein the internal tube (4) is partially or completely embedded in the medical-grade foam material (2), with a plurality of side-holes (5) for drainage formed in the tube wall, an end or an intermediate connecting opening of the internal tube (4) is positioned in a connector (6) away from the surface of the medical-grade foam material (2), the external connection tube (3) is in communication with the internal tube (4) via the detachable connector (6), and the rear end of the external connection tube (3) is connected to a negative pressure source. The connection between the external connection tube (3) and the internal tube (4) of the sealed drainage device under negative pressure is detachable, making it convenient for use and capable of achieving the transmission of a negative pressure over a large range.
