Description

Drainage sheet for ridge Technical Field The invention relates to a medical instrument for passive drainage of soft tissue wound surface, which can be used for discharging blood, pus, tissue fluid and the like in tissues to the outside, thereby being beneficial to tissue repair and wound healing. Background Clinically, wound drainage is an important treatment measure, the treatment measure is realized by placing drainage materials in operation, the current commonly used drainage materials comprise rubber drainage strips, common gauze drainage strips, cigarette drainage strips, oily gauze drainage strips, common silicone tubes, negative pressure suction tubes and the like, and the drainage materials have the advantages and the disadvantages of the drainage materials, and the indication has certain limitations. The rubber drainage strip is suitable for drainage of a shallow blood-permeable wound, is usually pulled out about 24 hours after operation and can not be replaced for disposable use, is suitable for deep wound drainage, is usually pulled out about 3 days after operation when drainage liquid is little, but has limited adsorption capacity, can not be replaced in time once adsorbed, but can play a role in obstructing drainage, the common gauze drainage strip can be replaced through dressing change, but is difficult to replace the cigarette drainage strip, is clinically eliminated at present, the oily gauze drainage strip is mainly used for fresh superficial wound surfaces and healthy granulation wound surfaces and can be replaced, the common silicone tube and the negative pressure suction tube are mainly used for drainage after operation of a cranial cavity, a thoracic cavity and a pelvic cavity, the retention observation time is long, the tube pulling index is dependent on the change of a disease state, the treatment cost is often high, but the rough appearance and the harder texture of the two are more difficult to bring certain pain and inconvenience to patients, the wound is more obvious after healing, and the negative pressure suction tube is connected with a corresponding negative pressure device, and the method has high professional operation. Disclosure of Invention In order to solve the defects of the drainage materials, the invention designs the ridge drainage sheet, and the device is not only suitable for drainage of shallow tissues, but also suitable for drainage of deep tissues, and can be used for fresh wound surfaces and infected wound surfaces, the sheet-shaped appearance of the device can relieve sequelae of scar healing, and the device can be cut into proper lengths and widths according to clinical needs, so that drainage selection of different wound surfaces is facilitated. Drawings FIG. 1 is a direct view of a ridge drainage sheet FIG. 2 side view of ridge drainage sheet FIG. 3 top view of ridge drainage sheet FIG. 4 bottom view of ridge drainage sheet FIG. 5 cross section of ridge drainage sheet Fig. 6 is a schematic structural diagram, in which: FIG. 6-1 ridge strip FIG. 6-2 ridge web FIG. 7 ridge stripe cross section Technical proposal The instrument is rectangular, has the length of 10cm and the width of 2cm (figure 1), the middle bulge part is provided with two ridge strips which are the same in size and shape and are arranged in parallel (figure 6-1), the distance between the two ridge strips is 0.6cm, and the cross section of each ridge strip is square with the side length of 0.1cm (figure 7). The part connected with the ridge strip is ridge web (figure 6-2), and the thickness of the ridge web is 0.01cm. According to the technical scheme adopted by the invention, the ridge drainage sheet is properly cut according to the position, width and depth of a wound surface in operation, the drainage sheet used after cutting at least comprises one ridge strip, after proper flushing by using 0.9% physiological saline solution, one end of the ridge strip is clamped by oval forceps or hemostatic forceps, toothed forceps and the like, slowly placed deep into a tissue along a wound surface gap, the direction of the ridge strip is consistent with a drainage path, the other end of the ridge strip is exposed to the outside of the skin a little, so that the dressing change operation is facilitated, sterile gauze is used for covering, binding and fixing, when the gauze is soaked by drainage liquid, the gauze is replaced in time, then a small amount of ridge drainage sheet is pulled out gradually by changing the dressing until the ridge drainage sheet is pulled out completely, and the ridge drainage sheet can be pulled out at a proper time according to the condition requirement. Advantageous effects The gap formed between the ridge strip and the ridge web of the ridge drainage sheet is beneficial to continuous outflow of liquid, the depth of the ridge drainage sheet in the body is continuously adjusted through dressing change, so that the wound surface is naturally closed from inside to outside, th
