Background technology
At present, arterial thrombus treatment may use thrombolysis catheter technology.For example, thrombolysis catheter treats acute lower limb arterial
The nursing intervention of thrombus is more typical, and acute lower limb arterial thrombus refers to that embolus comes off from heart or nearside arterial wall or outside
Boundary enters artery, pushes distal side to by blood flow, blocks artery blood flow and leads to limb ischemia so that a kind of pathologic process of necrosis, because
It falls ill hurried and gains the name.Disease treatment uses seldinger methods, i.e., penetrates blood vessel front and rear wall with the puncture needle with needle core, exit
Needle core slowly pulls out needle outward, until blood is sprayed from backshank, is rapidly inserted into seal wire, extracts needle, and conduit is introduced by seal wire, will
Conduit is put to aorta, through suffering limb homonymy or offside femoral artery puncture, is placed in conduit row radiography, is determined vascular occlusion position and journey
Degree, then row angioplerosis, is sent into seal wire, foley's tube to lesion segmented row balloon expandable, after expanding 3~5 times
Radiography again.If prompting oldness thrombosis, by thrombolysis catheter or below knee, artery uses microtubular at this time, and it is near to be placed in embolus
End is inserted into embolus, and 30~60min short time gives the u of urokinase 25~500,000, be usually no more than 1,000,000 u carry out it is molten in art
Bolt, it is unsuccessful can keep the catheter in embolus proximal end, outer end is fixed with skin, to urokinase with the speed of 800u~1000u/min
Micro to be pumped into, maximum dose is no more than 200~3,000,000 u.Continuously with 72h, row occluded blood vessel radiography detection ACT<200s,4h
After pull out arterial duct and sheath.Intravenous infusion tanshinone, " Xuesaitong Injection ", subcutaneous injecting of low molecular heparin calcium etc. simultaneously, are used in conjunction 7-10 days,
Change after deactivated heparin and take warfarin, maintain 3~6 months.The anti-bleeding of periodic detection coagulation function.
At present, thrombus thrombolysis catheter equipment was also connected with a more elongated conduit, manual injection device before equipment originally
Carry out pressure during blood thromboembolism treatment it is less than normal, it is uncontrollable, can not be long lasting for so as to influence thrombolytic effect, in addition, before implementing
Often include the syringe of hand pressure when stating class treatment with auxiliary appliance, by handle compressed spring, by the drug in syringe from
It gets out in outlet, due to the fatigue deformation in use of spring below, easily blocks often, and for a long time, high frequency time
Pressure handle, manipulation strength is larger, and medical staff people is more tired, and existing there has been no the equipment preferably substituted or automatic injections
Technology discloses.
