Abstract
The invention discloses a closed wound surface dressing device internally provided with washing instillation tubes. The dressing device comprises a first dressing layer and a second dressing layer, the multiple internally-arranged washing instillation tubes, a main tube, a negative pressure drainage tube and an externally-arranged washing instillation tube, wherein the first dressing layer and the second dressing layer are vertically arranged. The aperture of materials for manufacturing the second dressing layer is larger than that of materials for manufacturing the first dressing layer. The convergence ends of the internally-installed washing instillation tubes arranged between the first dressing layer and the second dressing layer are connected with the near end of the main tube. The far ends of the internally-installed washing instillation tubes are arranged on the edge of the first dressing layer. The main tube is perpendicularly arranged on the second dressing layer, and an opening in the far end of the main tube is formed outside the second dressing layer. The externally-arranged washing instillation tube is arranged inside the negative pressure drainage tube, the near end of the externally-arranged washing instillation tube is connected with the main tube, and the far end of the externally-arranged washing instillation tube penetrates out of the negative pressure drainage tube. The near end of the negative pressure drainage tube is provided with a suction-cup-shaped opening attached to the second dressing layer. The closed wound surface dressing device is simple in structure, low in cost and capable of effectively reducing the negative pressure wound surface treatment complication, and the treatment effect is improved.
Description
technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a closed wound dressing device with a built-in flushing drip tube. Background technique [0002] Negative Pressure Wound Therapy (NPWT) is a revolutionary development in the treatment of complex wounds in recent years. In 1992, German medical doctor Fleischmann pioneered the method of combining wound sealing with traditional negative pressure drainage to promote wound healing. This method was soon widely used in the coverage and drainage of various acute or chronic wounds on the body surface, ulcers, large soft tissue defects, tissue defects caused by war trauma, or exposed organs; in addition, this method can also Applied to the treatment of various infected soft tissue injuries. [0003] The open-pore dressing is the most important part in the application of the NPWT technique. The dressing packs and directly covers the wound tissue to keep the wound moist and cr...
