Abstract
This utility model relates to hydrophilic superslide coating excrement tracting tube.It is characterized in that, be made up of joint, body, body is made by variable intensity reinforcing mat knitting skill, adds reinforced wire in braid.Carry out pretreatment by the composite coupler prepared tube surfaces, then adopt hydrophilic monomer heat cross-linking mode to carry out graft reaction at catheter surface, finally the reacted catheter surface of grafting is dried, dry and be prepared from.Make it have the hydrophilic superslide coating of one deck, tube surfaces lubricates very much, easy and simple to handle in operation process, can reduce tissue injury, occurs organizing the probability of the complication such as hemorrhage, infection also greatly to reduce, also reduces the misery of patient simultaneously.
Description
Art
This utility model relates to medical instruments field, particularly hydrophilic superslide coating excrement tracting tube.
Technical background
Use field in medical treatment, when using excrement tracting tube to enter human body because common tube surface lubricity is inadequate, especially easily damaging human body and occurring that conduit blood back is existing, and inherently affecting medical effect like this, and the probability of happening of complication may be increased; In addition, in use often there is the large problem of frictional force in undressed excrement tracting tube, if excrement tracting tube surface lubrication is inadequate, also can increases operation easier, bring misery to patient.Thus needing effects on surface to carry out lubricated to reduce the painful and injury to patient of patient, existing coating generally uses methyl ethyl ketone as solvent, adopts independent UV crosslinking method, and this is to environment and make author and easily damage, and cost is higher.
Utility model content
This utility model is for solving above-mentioned technical disadvantages, this utility model is by the following technical solutions: carry out pretreatment by the composite coupler prepared tube surfaces, adopt hydrophilic monomer heat cross-linking mode to carry out graft reaction at catheter surface again, finally the reacted catheter surface of grafting is dried, dry and be prepared from.Make it have the hydrophilic superslide coating of one deck.Described composite coupler is by silane resin acceptor kh-550, and T0-80 surfactant and hydrophilic organic fluorine are dissolved in and are prepared from alcohol solvent.Described hydrophilic monomer can select NVP (NVP), polyvinylpyrrolidone (PVP), Polyethylene Glycol, poly(ethylene oxide), polyvinyl alcohol etc.
This utility model solves the defect existed in background technology, decreases solvent residual amount.Purify operating environment simultaneously, avoided the possibility of solvent contamination, the result of use simultaneously making excrement tracting tube reach excellent, reach the requirement of advanced medical apparatus and instruments.
Accompanying drawing explanation
Accompanying drawing is the sectional view of this utility model hydrophilic superslide coating excrement tracting tube body.
Wherein: 1 body, 2 joints.
Concrete implementing measure
Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is described in further detail:
In accompanying drawing, hydrophilic superslide coating excrement tracting tube, is made up of joint, body.
In accompanying drawing, body netting unit rhombus diagonal: 0.75mm × 0.98mm, adds reinforced wire in braid.
In accompanying drawing, body melt temperature is 100 DEG C-125 DEG C.
In accompanying drawing, tube surfaces composite coupler carries out pretreatment, then adopts hydrophilic monomer heat cross-linking mode to carry out graft reaction at catheter surface, finally dries the reacted catheter surface of grafting, dries and be prepared from.
