步骤2:对第一引流管61进行抽气，使负压切口愈合器内腔体形成负压，负压切口愈合器随体表变形，此时负压切口愈合器附着在体表，倒刺板324上的倒刺已刺入皮肤的表皮层，捏合第一支架31、第二支架32和第三支架33，使上咬合片325和下咬合片326完全咬合;在装置外通过第一支架31、第二支架32和第三支架33观察切口的对合情况。  Step 2: The first drainage tube 61 is evacuated, the negative pressure wound healing lumen body negative pressure, the negative pressure surface with the wound healing is deformed, the negative pressure at this time is attached to the body wound healing , barb barbs plate 324 has pierced the skin epidermis, kneading a first holder 31, second holder 32 and the third bracket 33, the upper engaging pieces 325 and 326 are fully engaged the engagement piece; means in the outer a first holder 31, second holder 32 33 and the third bracket observation slit of the case together.
步骤3:通过第一引流管61使负压切口愈合器内腔体形成稳定负压。  Step 3: the negative pressure wound healing stable suction lumen formed by a first drainage tube 61.
实施例1，按常规缝合皮肤层以下的各层组织，留切口的皮肤层不缝。  Example 1, layers of tissue by suturing the skin layer is less conventional, leaving the skin layer is not cut seam. 在切口边缘5CM范围涂抹已预制好的无菌润滑剂，根据切口皮肤裂开的距离，调节好每一个上咬合片325和每一个下咬合片326的初始咬合位置，将本装置覆盖于切口上端适当的位置，在轻压装置的情况下用类似直尺样的物件从装置底部申入，将所有折弯板329向中间擀平并压在皮肤上，通过第一引流管61对本装置抽气，并使本装置的内腔形成2个负大气压，此时装置已被吸附在皮肤上；同时捏合各个半圆拱架322，使上咬合片325和下咬合片326完全咬合；通过半园拱架322观察切口的闭合情况，如果切口闭合不到位，可轻摇半园拱架322，切口的两边将平整地贴合在一起。 In the range of the cut edge 5CM sterile lubricant applicator is prefabricated according to a distance incision skin breakdown, and 325 regulate the initial position of each of the engaging piece 326 engaging each of the engagement flaps, covers the upper end of the incision apparatus according to the present place, in the case of soft reduction device with a ruler-like objects from the bottom of the apparatus is similar to the application, all the bent plate 329 and the intermediate pressure level to roll on the skin, through the first drainage pipe 61 of the evacuation means, forming a lumen and apparatus of the present two negative atmospheres, at this time the device has been adsorbed on the skin; while kneading the respective semicircular arch 322, the upper engaging pieces 325 and 326 are fully engaged the engagement piece; by semi-circular arch 322 observation incision closed, if the incision is closed is not in place, can be rocked semicircular arch 322, the flat sides of the cut bonded together. 清洗并擦干本装置四周的皮肤，撕去半透贴膜4与皮肤之间的隔膜，贴好半透贴膜4，缓慢放进空气，使外接气压表指针维持在0.8个负大气压。 Washed and dried skin around the unit, between the semipermeable membrane tear film 4 with the skin, good paste semipermeable film 4, slowly into the air, so that the external barometer pointers maintained at 0.8 atm negative.
上咬合片325和下咬合片326的初始咬合位置可以手工调节，初始咬合位置可以根据切口的宽度来调节确定，在使用本装置前，手术者需测量切口的宽度，并根据切口的宽度事先调整好上咬合片325和下咬合片326的初始咬合位置，如果切口各段的宽度不一致，也可根据切口各段的宽度来调节对应咬合结构的初始咬合位置，使上咬合片325和下咬合片326的可滑进距离等于对应切口的宽度。  occlusal chip initial engagement position 325 and the nip plate 326 can be manually adjusted, the initial engagement position may be adjusted to determine the width of cut, before using the device, the operator need to measure the width of the slit, and in accordance with the cut width adjusted in advance the good engagement tab 325 and the initial engagement position of the engagement piece 326, if the width of each segment cutout inconsistent, but also to adjust the initial engagement position corresponding to the engagement structure according to the width of each section of the slit, the upper engaging pieces 325 and the engagement piece 326 can be slid by a distance equal to the width of the corresponding slit.
 可通过气压表观察装置内腔气压是否下常，可通过半园拱架322观察切口的闭合情况和切口周围皮肤的颜色，可通过半园拱架322观察装置内是否有大量积血，可通过半透贴膜4观察装置四周皮肤的颜色。  can observe whether the device lumen by the pressure gauge normally, by closing the semicircular arch 322 when the color was observed surrounding the incision and the incision of the skin, whether by blood in a large semicircular arch observation apparatus 322 , the skin color may be around the entire apparatus through a semipermeable film 4 was observed.
如果咬合结构滑脱，可及时更换装置;如果装置内切口边缘的皮肤变得暗黑，可能是因为气压表失灵而使装置内的负压过高，可更换气压表重新调整装置内的负压;如果短时间内装置内积聚了大量新鲜血液，是因为止血不彻底，可拆除装置，查找出血点，彻底止血后重新安上装置;如果出现皮肤严重搔痒或出现明显疹斑，是因皮肤过敏，必要时拆除装置缝合皮肤层。  If the slip engagement structure, means can be replaced; if the skin incision edges within the device becomes dark, possibly because of failure of the negative pressure in the pressure gauge device is too high, the negative pressure gauge can be replaced within the device readjust pressure; within a short time if the device amassed fresh blood, because bleeding is not complete, removable devices, look for bleeding, reattach the device after complete hemostasis; if there is severe itching skin rash or spots appear obvious, because the skin allergies, skin was sutured layer removal apparatus where necessary.
有必要时才可对切口进行冲洗，冲洗切口时装置内的负压应基本保持稳定，冲洗液可从第二引流管62滴入，从第一引流管61排出。  available for flushing incision if necessary, the negative pressure within the device should be substantially stable when flush cut, the rinse liquid can be dropped from the second drainage pipe 62, is discharged from the first drainage tube 61.
更换敷料时，须有助手一直压住装置，缓慢撕去弯盖2，依次夹出泡沫敷料5，再依次安放好新的预制的无菌泡沫敷料5，取一块新的预制的无菌弯盖2贴好，抽气至0.8个大气压，并维持在0.8个大气压左右。  When the dressing is changed, there must have been pressed against the assistant means slow tear-off cover bend 2, and the foam dressing clip 5, in turn placed well new prefabricated foam dressing sterile 5, to take a new prefabricated No bacteria good bending cover 2, evacuated to 0.8 atm, and maintained at about 0.8 atmospheres.
