Technical Field
The utility model relates to the technical field of medical equipment, more specifically say, in particular to a negative pressure drainage device for abscess treatment.
Background
Abscess is localized pus accumulation in tissues, organs or body cavities in the acute infection process due to necrosis and liquefaction of diseased tissues, and a complete pus wall is formed around the abscess.
Clinical treatment of abscesses is usually accomplished by incising or puncturing the pus wall of the abscess and draining the internal abscess.
However, the incision drainage method for abscess has the following defects:
firstly, for incision drainage of abscess, the incision is usually selected to be the most obvious position of wave motion at the top of the abscess, but deep abscess is difficult to position and can generate pain if expanded by hemostatic forceps;
secondly, after the abscess is cut and drained, the operation is complicated and the workload is large because the washing and dressing change are needed every day;
thirdly, abscess incision and drainage are carried out, the abscess flows outwards by means of the gravity of the abscess, and the drainage efficiency is low.
