Technical Field
[0001] The utility model belongs to the field of negative pressure drainage medical equipment, in particular to a drainage can accessory which is not easy to tip over. Background Art
[0002] Drainage cups are commonly used instruments for collecting exudates, blood, pus, etc. produced by various wounds during negative pressure suction therapy. They can be used in a variety of clinical drainage situations, such as trauma, burn wounds, chronic wounds, fistulas, and abscess incisions. At the same time, negative pressure suction technology can also promote the contraction of wound bed tissue, reduce the risk of infection, and help wound healing.
[0003] At present, the drainage cans used in clinical practice have the risk of tipping over when in use, especially when there is fluid accumulation in the drainage can. Once tipped over, it will not only cause waste liquid pollution on the ground, but also hinder the normal progress of subsequent drainage operations. Although most drainage cans have designs to prevent waste liquid overflow, such as check valves and water-blocking membranes, they are only effective for short-term tipping and still cannot play a good role when tipped over for a long time.
