Abstract
The invention discloses a central venous catheter capable of preventing thrombus. The central venous catheter comprises a central venous catheter body and medical coating layers coating the walls of the catheter. Each medicine coating layer comprises medicine and a medicine carrier, wherein the medicine is tissue factor pathway inhibitor TFPI-1 or TFPI-2, and the mass ratio of the medicine to the medicine carrier is 1:(4-7.9). Both the inner wall and the outer wall of the catheter body are coated with the medicine coating layers. The thickness of the medicine coating layers is 20-40 micrometers. The central venous catheter has the advantages that the tissue factor pathway inhibitor is applied to the central venous catheter body, so that thrombogenesis and bacterial infection in the central venous catheter body are effectively prevented, the pain and burden of a patient are reduced, the workload of medical staff is reduced, and working efficiency is improved. The tissue factor pathway inhibitor is tissue factor physiological inhibitor, has good blood compatibility and tissue compatibility compared with other medicine, has no toxic or side effect and has few influences on the human body.
Description
Technical field
The present invention relates to medical venous duct, particularly to a kind of can the central venous catheter of pre-preventing thrombosis.
Background technology
Central venous catheter is a kind of common medical apparatus and instruments, and it inserts the vein of patient by puncture technique, such as quiet in neck
Arteries and veins, infuses to patient.The clinical much client need central venous catheter that peripheral blood vessel condition is very poor is as vein
Transfusion path, owing to its misery is little, the advantage of indwelling time length is promoted clinically, but it is a series of also to put Guan Houhui generation
Send out disease, particularly conduit dependency thrombosis, not only add misery and financial burden to patient, bring tired to medical worker's work
Difficulty, once thrombus breaks loose causes pulmonary infarction even threat to life.
The main method preventing thromboembolism at present clinically is employing heparin in sealing after dialysis, and heparin in sealing repeatedly is not
But increase patient medical expense, and the heparin in pipe also can constantly be discharged in blood, increase bleeding risk.Locate clinically
Reason thromboembolism and the method for catheter blockage caused because fibrin sheath parcel are usually and repeatedly use after capsid is formed
Red cell morphology in urine, but poor effect.Red cell morphology in urine repeatedly there is drawbacks in that 1, somewhat expensive, and patient is difficult to bear, 2,
Urokinase has the complication of systemic bleeding, and life-threatening is exactly Complications of Cerebral Hemorrhage.Next to that use fibrin sheath to tear
Fibrin sheath is pulled out by de-art, but this operating difficulty is big, and general hospital is difficult to carry out, and operation needs to carry out under radiography,
Somewhat expensive.
So be badly in need of clinically a kind of can effectively in prevention center venous duct the new catheter of thrombosis to come elongation center quiet
The indwelling time of arteries and veins conduit, reduces misery and burden for patient, improves the work efficiency of medical personnel.
Summary of the invention
It is an object of the invention to overcome above-mentioned weak point and provide a kind of can the central venous catheter of pre-preventing thrombosis.Catheter wall
On have medication coat, medication coat is tissue factor pathway inhibitor, and tissue factor pathway inhibitor is the physiology of tissue factor
Inhibitor, compared with other drug, has good blood compatibility and histocompatibility.
The present invention adopts the following technical scheme that.
Can the central venous catheter of pre-preventing thrombosis, including central venous catheter and the medication coat that is coated on catheter wall, institute
Stating medication coat and include that medicine and pharmaceutical carrier, described medicine are tissue factor pathway inhibitor, described tissue factor approach presses down
Thing processed is TFPI-1 or TFPI-2, and medicine is 1:4～7.9 with the mass ratio of pharmaceutical carrier.Described medication coat thickness be 20～
40 microns.
Described medicine is TFPI-1.
Described medicine is TFPI-2.
Medication coat is all had on the wall of described conduit and outer wall.
The wall of described conduit has medication coat.
Described medication coat, medicine is 1:4 or 1:7 with the mass ratio of pharmaceutical carrier.
Described medication coat thickness is 25 microns or 35 microns.
It is an advantage of the current invention that:
Tissue factor is the startup factor of exogenous cruor pathway.Under physiological conditions, the hemocyte directly contacted with blood circulation
With the endotheliocyte not expression tissue factor, when vascular endothelial cell is impaired, tissue factor exposes thus activates platelet, promotes
Adhere to each other between platelet and gathering causes Intravascular Thrombus to be formed.
Tissue factor pathway inhibitor is discharged as the medicine of central venous catheter medication coat in conduit, not only may be used
With thrombosis in prevention conduit, and the use of anticoagulant can be reduced, thus reduce incidence rate and the treatment cost of bleeding episode
With, and owing to only discharging in conduit, functioning efficiency is high, and little on the impact of whole body blood coagulation system.
1. tissue factor pathway inhibitor is applied in central venous catheter, sending out of thrombosis in venous patient conduit can be made
Raw rate reduces.
2. the incidence rate that can make patient's bleeding episode reduces.
3. tissue factor pathway inhibitor is the physiological inhibitor of tissue factor, compared with other drug, has good
Blood compatibility and histocompatibility, have no side effect, little effect on the human body.
