Negative pressure sealing drainage device of surface wound tissue

Abstract

A negative pressure sealing drainage device of a surface wound tissue comprises a porous foam cushion (1) which contacts with the surface wound, a drainage tube (2) with a side port, a sealing film (3), a connector (4), a catheter (17), a drainage container (5), a negative pressure source (6), an adhesive film (7) and an eduction tube (8), The adhesive film (7) is located above the porous foam cushion (1); the opening direction of the side port on the drainage tube (2) contacts with the porous foam cushion (1); the eduction tube (8) is communicated with the drainage tube (2) and located abovethe adhesive film (7); the sealing film (3) is sealed on the adhesive film (7); the eduction tube (8) is pumped into the drainage container (5) through the catheter (17); and the drainage container (5) is connected with the negative pressure source (6) through the catheter (17). The device leads the porous foam cushion to be capable of prolonging the time of maintaining flexibility and moist environment, is beneficial to wound healing, and has the advantages of convenient and reliable sealing and drainage.

AI Technical Summary

Benefits of technology

This patented technology describes a new type of surgery that uses special equipment called vacuum suction systems. These machines have tiny holes inside them where blood flows easily without leaking outside. They work by creating a tightly fitting layer between two layers of material like plaster films. When these layers stick together they expand slightly overall, allowing fluids to flow freely within this space while keeping everything dry. It'll help keep your heart function well but still allow gases to escape quickly due to its small size compared to traditional methods such as stoma castings. Overall, this innovation improves medical procedures and makes better results.

Problems solved by technology

Technicians have developed different techniques called vacuum sewings (VSS) and liquid nitrate infusion therapy (LNIT), each being effective against various types of bacteria present during wounding conditions. These technologies aim to provide an improved way to treat these issues while reducing patient complications caused by excessive blood flow inside affected areas.
