Technical Field

[0001] The invention relates to the field of medical technology, and in particular to a medical wound positive pressure flushing and negative pressure suction device. Background Art

[0002] In daily clinical work, there are often a large number of wounds that need to be treated, such as trauma, burns, bedsores, skin defects, infected wounds, postoperative wounds, osteomyelitis, deep infections, etc. Generally, smaller and shallower wounds can be healed by changing the dressing with conventional gauze. However, it is very difficult to treat complex, deeper, larger, more exudative, and long-term non-healing wounds. They require one or more dressing changes a day, flushing the wound with medicated liquid, and using dry gauze to absorb the exudate from the wound.

[0003] In clinical surgery, almost all surgeries require flushing of the surgical site. The most primitive empty needle aspiration flushing fluid flushing or conventional negative pressure equipment to generate negative pressure, and then connect the surgical instruments for flushing. Both of these methods are likely to cause waste liquid to splash and flow outside the operating area after flushing, causing pollution. In addition, ordinary positive pressure flushing and negative pressure suction work are carried out in two steps, with low work efficiency and easy to cause wound infection. At the same time, ordinary positive and negative pressure equipment cannot be adjusted in height, and the position adjustment is inconvenient.
