Abstract
The utility model discloses an anti central ductus venosus that rolls over, including the pipe body, the pipe body includes main duct, branch pipe and is located the catheter connection seat of main duct and branch pipe linking department, branch pipe is provided with one at least, the main duct includes the pipe body and wears to establish the seal wire in the pipe body, the seal wire includes stamen silk and wire winding cover, the pipe body is made by the plastic material that has the shape memory, the wire winding cover is formed by the heliciform wire winding that the superpose was arranged, the stamen silk is made by the shape memory material for the stamen silk still can keep the initial condition of preferred after bending many times, and make the pipe still can keep the on-state under the circumstances of rolling over through heliciform wire winding cover, prevents the emergence of medical accident.
Description
Technical field
This utility model relates to a kind of anti-Rebate Center venous duct be used as on clinical medicine.
Background technology
Central venous catheter (central venous catheter, CVC) belongs to the one of Ink vessel transfusing pipe, is positioned in large vein.Its main uses: measuring center venous pressure (central venous pressure, CVP), in order to assessments physiological parameter, and estimates body fluid number.Because measure this purposes of CVP, often claim using CVP as the blackmail of CVC in Taiwan hospital; Venous transfusion in a large number and fast, often appears at the operation that blood loss may be larger, or maintains blood pressure during first aid; What long-term parenteral, long-term injection of antibiotic, chronic analgesic medicine were injected gives approach; For peripheral veins (venule) compared with the irritating medicine of tool, change and inject from central venous catheter.Such as: Amiodarone etc.; The pipeline of hemodialysis, as plasmapheresis or wash kidney.But in actual use, be non-straight spool due to blood vessel and have bending more, therefore easily there is the situation about blocking that gives a discount in conduit, affects, even jeopardize the life security of patient to the treatment of patient.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of anti-Rebate Center venous duct.
This utility model solves the technical scheme that its technical problem adopts:
Anti-Rebate Center venous duct, comprise catheter body, described catheter body comprises main pipe, a conduit and is positioned at main pipe and the tubes connection seat propping up conduit joining place, described conduit is at least provided with one, described main pipe comprises catheter tube and is located in the seal wire in catheter tube, described seal wire comprises stamen silk and coiling cover, described catheter tube is made by there being the plastic material of shape memory, described coiling cover is formed by the spiral wrapping wire of stacked arrangement, and described stamen silk is made up of shape-memory material.
Described catheter tube is made up of medical silica-gel material.
Described stamen silk is made up of Nitinol.
Described coiling cover is formed by the helical form steel wire of stacked arrangement.
Described stamen silk is made up of the filament of many.
The beneficial effects of the utility model are: anti-Rebate Center venous duct, comprise catheter body, described catheter body comprises main pipe, prop up conduit and be positioned at main pipe and the tubes connection seat propping up conduit joining place, described conduit is at least provided with one, described main pipe comprises catheter tube and is located in the seal wire in catheter tube, described seal wire comprises stamen silk and coiling cover, described catheter tube is made by there being the plastic material of shape memory, described coiling cover is formed by the spiral wrapping wire of stacked arrangement, described stamen silk is made up of shape-memory material, make stamen silk still can keep preferably initial condition after repeatedly bending, and still can keep conducting state under making conduit situation on sale by spiral helicine coiling cover, prevent the generation of malpractice.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is generalized section of the present utility model.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, Fig. 1, Fig. 2 are the structural representations of this utility model specific embodiment, as shown in the figure, anti-Rebate Center venous duct, comprise catheter body, described catheter body comprises main pipe 10, a conduit 92 and is positioned at main pipe 10 and the tubes connection seat 90 of conduit 92 joining place, props up conduit 92 end and is provided with the union joint be connected with syringe, the quantity of propping up conduit 92 is determined by the kind of infusing simultaneously, is generally 1 ~ 3.
Described catheter tube 1 is made by there being the plastic material of shape memory such as medical silica-gel material, described coiling cover 3 is formed by the spiral wrapping wire of stacked arrangement, described stamen silk 2 by shape-memory material as Nitinol is made, make stamen silk 2 still can keep preferably initial condition after repeatedly bending, reduce when seal wire is walked or the resistance in the time of extracting, reduce the injury to blood vessel and tissue, reduce the misery of patient, and still can keep conducting state under making conduit situation on sale by spiral helicine coiling cover 3, prevent the generation of malpractice.
As preferably, in the present embodiment, described catheter tube 1 is made up of medical silica-gel material, described coiling cover 3 is formed by the helical form steel wire of stacked arrangement, there is provided certain support force can to catheter tube 1 tube wall by this helical form steel wire, under lateral pressure, catheter tube 1 still can be made to keep conducting state, can effectively prevent conduit to be extruded and narrow and block, improve its safety.
Above better enforcement of the present utility model is illustrated; certainly; this utility model can also adopt form different from the embodiment described above; as stamen silk 2 can be combined into by the filament of many; its shape memory restorability of further raising; 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 domain of the present utility model.
