Detailed description of the invention
As can be seen from Figure 1, a kind of flushable Wound-surface negative pressure of this utility model repairs dressing, and it is made up of spongy body 1, sucker irrigator 2, irrigating catheter 3, syringe pipe 4.Spongy body 1 is made up of composite polyvinyl alcohol (PU) porous material.Described sucker irrigator 2 comprises sucker 21, rinses feed tube 22, drain drain pipe 23, flush-through connection 24, flow sub 25, as shown in Figure 2.Rinse feed tube 22 in described sucker irrigator and be positioned at centre, drain drain pipe 23 is 4, is distributed in and rinses feed tube 22 both sides.Rinse feed tube 22 and connect flush-through connection 24, for connecting, injecting processing solution.Drain drain pipe 23 connects flow sub 25, for connecting Negative pressure machine, and the liquid on drain wound face.
Feature of the present utility model is: described spongy body 1 comprises upper strata sponge 11, lower floor sponge 12, described syringe pipe 4 is arranged between upper strata sponge 11 and lower floor sponge 12, sucker 21 on described sucker irrigator is fastened on upper strata sponge 11, described irrigating catheter 3 compression is placed in the installing hole of upper strata sponge 11, and its two ends are communicated with bottom syringe pipe 3 with the flushing feed tube 22 of top sucker irrigator 2 respectively.
This utility model spongy body is totally divided into two-layer, is divided into does not press close to wound surface layer and drain layer according to function difference.The upper strata sponge 11 of described spongy body is drain layer, and it is thicker macrovoid PU sponge, and its hole is 800-1500 μm.Drain layer is based on hydrophobic requirement, adopt polyurethane material, simultaneously because drain layer does not exist the problem that granulation tissue grows into, it is the tissue fluid of drain local necrosis that major function requires, select larger aperture, simultaneously the hydrophobic property of polyurethane material also ensure that the abundant drain infecting medium, tissue necrosis material and antibacterial.After suction function, upper strata sponge 11 can not be hardening.Lower floor sponge 12 is for pressing close to wound surface layer, and it is thinner fine pore PU sponge, and its hole is 600-800 μm.This effectively ensure that the unobstructed of negative pressure drainage, and can effectively avoid growing into of new granulation tissue, reduce more change dressings time bleeding risk, alleviate the pain of the wounded.The hydrophobicity of dressing is obviously relevant to blockage of the micro orifice rate, and polyurethane is hydrophobic material, effectively can reduce albumin and fibrinogenic absorption.Due to the adhesion mainly hydrophilic adhesion of antibacterial, select hydrophobic material also effectively can reduce the adhesion of antibacterial simultaneously.Therefore polyurethane material is selected effectively can to prevent depositing of the blocking of micropore and antibacterial.The connection of described upper strata sponge 11, lower floor sponge 12 realizes by high frequency heat seal and glue bond two kinds of modes.
Described syringe pipe 4 is clipped between upper strata sponge 11 and lower floor sponge 12.Syringe pipe 4 is grid type syringe pipe, can rinse to surrounding radiant type, extends to dressing edge pressing close to wound surface layer.Flushing liquor or disinfectant solution can be made in full dressing distribution and pressure uniform, effectively prevent the short stream of flushing liquid in dressing.As shown in Figure 3.Described grid type syringe pipe has some flushing through holes.The connection supervisor of grid type syringe pipe protrudes the installing hole being arranged in upper strata sponge 11 and being provided with.In interlayer, flushing liquor can be directly flushed to lower floor sponge and sponge edge by syringe pipe, plays good developing result.
Described irrigating catheter 3 is spring conduit.As shown in Figure 1.Spring conduit two ends are with connecting bend, and the flushing feed tube on sucker irrigator is also with union joint.Described spring conduit two ends are connected with described flushing feed tube 21 and syringe pipe 3 by connecting bend, and fix by connecting buckle.
When this utility model uses, first by clean for the wound and wound surface of patient clean, size according to wound surface selects washable negative pressure drainage dressing, or cutting and wound surface match, and be placed on clean wound surface, cover with the transparent sticking film of biology, sucker irrigator 2 is placed in the central authorities above whole dressing upper strata sponge 11. and connect HC negative pressure system by sucker irrigator 2 or be connected to form drainage system with vacuum suction machine.Liquid is by syringe pipe to the surrounding of spongy body, and drain is power with vacuum suction, is circulated to heart channel sucker in spongy body and reclaims.
This utility model can carry out drain and flushing respectively, also can carry out drain and flushing simultaneously, realize limit and take out negative pressure limit pre-washing function, under suction function, liquid can conduct to dressing surrounding simultaneously, reclaimed by the sucker of central authorities, can realize comprehensive flushing of spongy body, effectively pre-blockage resisting, is conducive to the effect of removing foreign body and antibacterial.Medical sponge body can be rinsed over the course for the treatment of repeatedly, avoids spongy body in wound negative pressure treatment process occur drying up and blocking and cause the generation of the phenomenons such as inadequate drainage.Its structure is rationally, easy for operation, decreases the number of times of changing dressings, reduces the probability of clinical infection, clinical manipulation safe ready.
