Detailed Description

The embodiments of the present invention will be described in more detail with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the embodiments of the present invention after studying the specification. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

The utility model provides a convenient-to-use negative pressure drainage device as shown in figures 1-3, which comprises a dressing layer 1 covering a wound surface, a sealing film 2 for fixing the dressing layer 1 on skin, a drainage hole 21 formed in the sealing film 2, a drainage tube 3 and a negative pressure machine connected to one end of the drainage tube 3, wherein the sealing film 2 is also provided with a standby drainage hole 22, the drainage hole 21 and the standby drainage hole 22 are both connected with a one-way valve 4, the one-way valve 4 is connected with a connector tube 5, the connector tube 5 of the standby drainage hole 22 is detachably connected with a plug 6, the other end of the drainage tube 3 is provided with a connector 7, and the connector 7 is detachably connected with the connector tube 5 of the drainage hole 21; a fixing part 8 is also arranged between the one-way valve 4 and the sealing film 2.

The negative pressure machine is used for generating negative pressure; the dressing layer can be made of polymer medical sponge and is filled on the wound surface after debridement; the sealing film can be made of a biological semipermeable membrane, so that the dressing layer is fixed with the skin around the wound surface, the wound surface is isolated from the external environment, and bacterial infection is prevented. The sealing film is also provided with a drainage hole and at least one standby drainage hole, as shown in figures 2 and 3, the drainage hole is sequentially connected with a one-way valve, a mouthpiece, a connector and a drainage tube, and the standby drainage hole is sequentially connected with the one-way valve, the mouthpiece and a plug; the one-way valve can be a plastic one-way valve and is used for preventing seepage and external air from flowing back when the drainage tube or the plug is disassembled; the interface tube is detachably connected with the joint and the plug in a threaded connection, splicing and other modes, and can be quickly disassembled and assembled while the sealing performance is ensured. The fixing part is used for enhancing the structural stability among the one-way valve, the mouth-piece and the sealing film and can be made of silica gel. Furthermore, a storage bottle is arranged on the drainage tube, and exudates sucked out from the drainage port flow into the storage bottle for temporary storage, so that the negative pressure machine is prevented from being polluted.

During negative pressure treatment, the standby drainage hole is sealed by the plug, and the joint of the drainage tube is connected with the mouth piece of the drainage hole; when the drainage hole is blocked, the plug is detached from the standby drainage hole, the connector of the drainage tube is connected with the interface tube of the standby drainage hole, and finally the interface tube of the drainage hole is sealed by the plug, so that the effective service time of the negative pressure drainage device is prolonged, and the treatment cost is reduced; when non-negative pressure treatment is carried out, the joint can be detached, and then the plugs are used for sealing all the drainage holes and the standby drainage holes, so that the patient can move freely.
