Abstract
The invention discloses an anesthesia catheter with a hydrophilic coating at the front section, which comprises a catheter body, wherein the hydrophilic coating is arranged at the end part of the catheter body and consists of a high polymer or a monomer with a hydrophilic group, the hydrophilic coating with the advantages of adhesion resistance, high lubricity, biosafety, stability and wear resistance is formed on the surface of the catheter body, the resistance of the catheter during the threading and the pulling-out is reduced, the thrombus is reduced, the harm to human tissues can be minimized, and the catheter has higher practical value.
Description
Technical field
The present invention relates to a kind of anesthetic tube of the front length of tape hydrophilic coating be used as on clinical medicine.
Background technology
Epidural Block is most popular anesthesia clinically, namely pass through with after anesthesia spinal needle puncture, tract along anesthesia spinal needle imports conduit in epidural space, then inputs the medicines such as anesthetics and blocks, thus reach the object of anesthesia.Usually the conduit being used for anaesthetizing clinically is all adopt PVC or nylon material to make, because anesthetic tube needs to be inserted into for a long time in blood vessel or epidural space, this can cause the top layer of tissue adsorptions to conduit of blood vessel, tract, epidural space, increase the resistance that conduit is extracted, and easily cause thrombosis and assembling damage, and when inserting to walk resistance large.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of anesthetic tube of front length of tape hydrophilic coating.
The technical solution adopted for the present invention to solve the technical problems is:
The anesthetic tube of front length of tape hydrophilic coating, comprises catheter body, and described catheter body end is provided with hydrophilic coating.
Described hydrophilic coating is made up of the high molecular polymer or monomer with hydrophilic group.
Described catheter body is also provided with some stripeds with the scale that makes a check mark.
Some spiral helicine support steel rings are provided with in described catheter body.
Seal wire is provided with in described support steel ring.
The invention has the beneficial effects as follows: the anesthetic tube of front length of tape hydrophilic coating, comprise catheter body, described catheter body end is provided with hydrophilic coating, this hydrophilic coating is made up of the high molecular polymers such as acetals polymer, hydrophilic polymer and citric acid ester plasticiser or monomer, formed on the surface of catheter body antiseized glutinous, lubricity is high, bio-safety, stablize wear-resisting hydrophilic coating, reduce resistance when conduit is walked and extracted, reduce thrombosis, and can will be down to minimum to the injury of tissue, there is higher practical value.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
With reference to Fig. 1, Fig. 1 is the structural representation of the present invention's specific embodiment, as shown in the figure, the anesthetic tube of front length of tape hydrophilic coating, comprise catheter body 1, it is characterized in that: described catheter body 1 end is provided with hydrophilic coating 2, as preferably, this hydrophilic coating 2 is by acetals polymer, hydrophilic polymer and citric acid ester plasticiser form by a certain percentage, preferred proportion is acetals polymer 20 ~ 35%, hydrophilic polymer 35 ~ 65%, citric acid ester plasticiser 12 ~ 25%, formed antiseized glutinous on the surface of catheter body 1, lubricity is high, bio-safety, stablize wear-resisting hydrophilic coating, reduce resistance when conduit is walked and extracted, reduce thrombosis, and can will be down to minimum to the injury of tissue, there is higher practical value.
As preferably, described catheter body 1 is also provided with the striped 3 of some scales that makes a check mark, facilitates medical worker to determine the position of conduit.
As preferably, some spiral helicine support steel ring (not shown)s are provided with in described catheter body 1, to improve the anti-pressure ability of catheter body 1, in described support steel ring, be provided with seal wire (not shown), to improve the anti-discounting ability of catheter body 1.
Medical bio hydrophilic coating, that also applies comparatively in armarium is extensive, mentioned component ratio is only a wherein preferred component ratio of the present invention, this hydrophilic coating also can adopt the compositions such as high molecular polymer or monomer such as polyurethane-urea, polyacrylic acid, polyacrylamide, POLYPROPYLENE GLYCOL, polyacrylic acid acrylamide, is not described further at this.
Above better enforcement of the present invention is illustrated; certainly; the present invention can also adopt form different from the embodiment described above; the equivalent conversion that those of ordinary skill in the art do under the prerequisite without prejudice to spirit of the present invention or change accordingly, all should belong in protection scope of the present invention.
