[0037] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0038] like Figures 1-4 As shown, a micro-negative pressure drainage wound dressing includes a dressing body 1:

[0039] The dressing body 1 has a drug placement groove 3 on its lower surface and a hollow sleeve 2 on its upper surface. The dressing body 1 has several drainage holes 5 that connect the drug placement groove 3 and the hollow sleeve 2. The hollow sleeve 2 is equipped with a negative pressure tube 7 that is connected to a micro negative pressure source. When wound treatment medication is placed in the drug placement groove 3 and the dressing body 1 is attached to the wound, the negative pressure drainage from the micro negative pressure source will have a negative pressure effect on the body fluid exuded in the wound. This will allow the exuded body fluid to enter the hollow sleeve 2 through the drainage holes 5 and flow out through the negative pressure tube 7, thus achieving a negative pressure drainage effect on the body fluid exuded in the wound.

[0040] The inner wall of the medicine placing groove 3 is provided with a plurality of drainage members 4, which can form a plurality of relatively independent drainage channels in the medicine placing groove 3, so as to perform multi-point negative pressure drainage operation on the body fluid exuded from the wound surface in the medicine placing groove 3, improve the negative pressure drainage rate of the body fluid in the wound surface, and ensure that the body fluid exuded from the wound surface can be quickly and stably drained by negative pressure.

[0041] The drainage member 4 includes a drainage tube 41, the length of the drainage tube 41 is less than the depth of the medicine placing groove 3, and the bottom of the drainage tube 41 does not directly contact the skin of the wound surface, avoiding secondary extrusion damage of the drainage tube 41 to the wound surface, and at the same time, the drainage tube 41 can form an independent drainage channel in the medicine placing groove 3, and has a multi-point independent drainage effect on the body fluid exuded from the wound surface.

[0042] A plurality of through holes 42 are arranged on the drainage tube 41 in a spaced manner, which increases the passage area of the body fluid into the drainage tube 41 and accelerates the negative pressure drainage rate of the body fluid.

[0043] The bottom of the drainage tube 41 is provided with an elastic ring 43, when the dressing body 1 is compressed and deformed by external force, the elastic ring 43 will contact the skin of the wound surface and be deformed, which can play a flexible buffering role on the skin of the wound surface, avoiding secondary extrusion damage to the skin of the wound surface.

[0044] A foaming layer 6 is arranged in the dressing body 1 and between the medicine placing groove 3 and the drainage hole 5, the body fluid not drained from the drainage tube 41 in the medicine placing groove 3 will seep into the foaming layer 6, so that the foaming layer 6 is deformed and expanded, and the body fluid is again negatively drained into the empty drum sleeve 2 through the drainage hole 5, realizing the high-efficiency negative pressure drainage effect of the wound exudate.

[0045] The vertical end inner wall of the medicine placing groove 3 is provided with a blocking piece 12, which can form a blocking structure in the circumferential direction of the medicine placing groove 3, preventing the body fluid exuded from the wound surface from wetting the dressing body 1.

[0046] The bottom of the dressing body 1 and outside the medicine placing groove 3 is provided with an adhesive ring 11, which is adhered to the skin outside the wound surface, so as to fix the dressing body 1 to the skin.

[0047] The negative pressure tube 7 is provided with an adhesive tape 8, which is adhered to the skin, so as to reinforce the position of the negative pressure tube 7.

[0048] Further comprising a connecting member 9, the connecting member 9 includes a connecting tube 91 arranged at the end of the negative pressure tube 7, and a compression ring 92 is arranged on the connecting tube 91, the connecting tube 91 is sleeved on the negative pressure interface of the micro negative pressure source, and the compression ring 92 is moved to the outside of the overlapping position of the connecting tube 91 and the negative pressure interface, so as to extrude and reinforce the two, avoiding the falling of the connecting tube 91.

[0049] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
