Concrete using method is as follows:
One. the placement of subcutaneous drainage tube:
When being applied to prevent infection of incisional wound: select the barrel section of respective diameters for use according to the hypodermic thickness of otch, the tension force of principle when not increasing skin suture.Incision length is according to actual needs cut out the barrel section, the barrel section is connected with tapering joint A to be positioned over before the abdominal muscle between the fascia and subcutaneous fat then, from the otch upper and lower side in addition puncture draw, have the barrel section of side opening part can not exceed skin.Sew up subcutaneous tissue and skin again, need closely can not leak.Sew up and finish with normal saline examination flushing, encrypt if any leaking to sew up separately.Sewing up two punctures at last fixes the drain pipeline section.The direction that the drain pipeline section is placed is generally an end that connects flushing liquor and is positioned at the otch proximal part.
When infection of incisional wound taking place: all patients wash otch with 3% hydrogenperoxide steam generator and III type An Er iodine solution after removing subcutaneous slough, the 500-1500ml normal saline flushing is clean.Select the barrel section of respective diameters for use according to the hypodermic thickness of otch, the tension force of principle when not increasing skin suture.Incision length according to actual needs partly carries out cutting with the barrel section, the barrel section is connected with the tapering joint to be positioned over before the abdominal muscle between the fascia and subcutaneous fat then, from the otch upper and lower side in addition puncture draw, have the barrel section of side opening part can not exceed skin.Sew up subcutaneous tissue and skin again, need closely can not leak.Sew up and finish with normal saline examination flushing, encrypt if any leaking to sew up separately, sew up two punctures at last the drain pipeline section is fixed.The direction that the drain pipeline section is placed is generally an end that connects flushing liquor and is positioned at the otch proximal part.
Two. the flushing of subcutaneous drainage tube and vacuum suction:
Second day after operation begins to mould the pin reason saline continual rinsing of delivering a child with single head.Single head is moulded the joint that pin is similar to transfusion device, use clinically more convenient, similar with clinical transfusion, mould the rubber stopper that pin directly inserts infusion bottle by single head.Flow control valve can be regulated the flow velocity of flushing liquor, and is similar to clinical transfusion.Lower end tapering joint connects the central negative pressure that negative pressure drainage vessel connects hospital.By regulating the pressure of hospital's negative pressure device, can realize the adjusting of otch internal pressure.Keep between the negative pressure 100 ~ 150mmHg(1mmHg=0.133kPa) and continue aspirating.Flushing liquor is adjusted and is dripped speed and be about 40-50 and drip/min.
Three, pulling out of subcutaneous drainage tube:
Wash after 3 days and to pull out this drainage tube in the 4th day.If the slough that drainage tube is drawn is more, the time of pulling out drainage tube can be prolonged according to actual needs.Of the present inventionly be designed to the tapering joint and the barrel section is separable, drainage tube can be divided into two parts.So firmly pull out simultaneously at two ends up and down from otch when pulling out drainage tube, the tapering joint separates in otch with the barrel section, extract at two ends up and down from otch respectively, after extracting, a little sepage is often arranged in the subcutaneous tissue tunnel, can push otch with gauze from top to bottom, a small amount of hydrops in the otch is extruded, cause infection of incisional wound after avoiding gathering.
Four. the placement of subcutaneous drainage tube, the main points of flushing and vacuum suction:

3. Chong Xi purpose is to keep the unobstructed of drainage system, guarantees to keep under suction function in the otch environment of moistening drying.The portion of tissue that subcutaneous tissue still has after surgery continues downright bad, if simple vacuum suction is easy to make drainage tube to stop up, behind the normal saline washing, the Chang Kejian slough is gone out.Spill from otch but have liquid during the excessive and vacuum suction insufficient pressure of pressure of flushing, make the cut surface humidity, increase infection rate on the contrary, the height of scalable rinsing bottle is regulated the pressure of flushing.
4. pressure is advisable with 100 ~ 150mmHg during vacuum suction.Because the quality of barrel section is softer, and tube chamber subsides, and side opening presses off, effectively the barrel section reduced when pressure was excessive, and subcutaneous tissue also is close to the barrel section too greatly because of suction and is stopped up side opening, and drainage effect reduces on the contrary.When pressure was too small, drainage effect was weak and have liquid to spill from cut surface.
5. obesity or postoperative subcutaneous tissue are discharged more slough person, carry out I ﹠ A though placed subcutaneous drainage tube, but subcutaneous drainage tube ratio is easier to stop up, slough easily remains in the subcutaneous antipriming pipe, so should postoperative in 3 days every day repeatedly strengthen flushing flow rate and negative pressure, get express developed the slough in the barrel section gone out in several minutes after slowly flushing again.
6. drainage tube should not be placed for a long time, and general 3-5 days, drainage tube itself was as foreign body, and the surface has bacteria planting easily, places on the contrary as the source of infection for a long time.
