Embodiment: referring to Fig. 1, the subcutaneous irrigation drainage tube of the combination type that a kind of blockage resisting is two-way circulated among the figure, comprise the feed flow pipeline section, the barrel section, the drain pipeline section, this barrel section comprises that center tubes and N is radial outward extending supporter along center tubes, the drainage channel that the center tubes outside is divided into N sector region of supporter, the outside of supporter is provided with outer tube wall, outer tube wall is provided with N the bar shaped notch corresponding with N sector region as draining hole, described center tubes sidepiece is provided with several flushing holes center tubes inside is communicated with sector region, the one end sealing of central canal, one end opening, N 〉=3;
Described feed flow pipeline section one end is that single head is moulded pin, be provided with the tapering joint of coupling between one end of the center tubes opening of the other end of feed flow pipeline section and barrel section, described feed flow pipeline section is provided with flow control valve, the outer wall access anchor tip of one end of the center tubes sealing of described barrel section and an end of drain pipeline section link into an integrated entity, and the other end of drain pipeline section is provided with the tapering joint.
Described feed flow pipeline section, barrel section, drain pipeline section are flexible hose.
Described single head is moulded pin, two tapering joints, anchor tip materials are ABS; Flow control valve is PP; The barrel section is PU.
Concrete using method is as follows:
One. the placement of subcutaneous drainage tube:
When being applied to Incision infection prevention: select the barrel section of respective diameters 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, then the barrel section is connected with tapering joint A to be positioned over before the abdominal muscle between the fascia and subcutaneous fat, 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 again subcutaneous tissue and skin, need closely can not leak.Sew up and finish with normal saline examination flushing, encrypt if any leaking to sew up separately.Sewing up at last two punctures 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 occuring: 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 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, then the barrel section is connected with the tapering joint to be positioned over before the abdominal muscle between the fascia and subcutaneous fat, 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 again subcutaneous tissue and skin, need closely can not leak.Sew up and finish with normal saline examination flushing, encrypt if any leaking to sew up separately, sew up at last two punctures 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 utility modelly 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:
1. peritoneum and skin closure are tight, and placing drainage makes subcutaneous tissue become one " negative pressure cavity ", but can not leave dead space after connecting negative pressure, plays sufficient active drainage, prevents fluid accumulation, bacterial reproduction.
2. the large I of barrel section diameter is suitably selected according to hypodermic thickness, and the tension force when not increasing skin closure is advisable, and there is no fixed standard in.
3. the purpose of flushing 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 still has subcutaneous tissue after surgery continues downright bad, if simple vacuum suction is easy to make blocked drainage tube, 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 cut surface moist, increase on the contrary infection rate, the height of adjustable flushing 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 too greatly the barrel section 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 although 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 more slowly flushing.
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.
