Description
Technical field
The present invention relates to a kind of medical supplies, particularly hemodialysis to be correlated with medical equipment.
Background technology
Existing hemodialysis catheter can couple together with blood circuit and dialysis machine before first time uses, and carries out pre-flush by extracorporeal circulation passage, but because conduit inserts human body during follow-up repeatedly use, therefore cannot recycle dialysis machine and rush in advance.Hemodialysis catheter is after use, and can remain a small amount of blood in conduit, after a period of time, blood can solidify formation thrombosis, easily causes blood vessel blockage when reusing, and affects hemodialysis.In current practice, in order to prevent blood vessel blockage, doctor can hold some medicines and take to patient, prevent blood coagulation by the method for medicine, but medicine is containing three points of poison, for the patient that health is bad, if extra drug administration, the undoubtedly burden of making patients again.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of and can remove the method being set in the thrombosis of dialysis catheter.
The solution that the present invention solves its technical problem is: a kind of hemodialysis catheter purging method, comprises the following steps: A, on dialysis catheter, be provided with joint; B, solution is injected in flusher; C, flusher and flush-through connection to be tightly connected; D, the solution in flusher to be injected in dialysis catheter.
As the further improvement of technique scheme, described joint is standard luer fittings.
As the further improvement of technique scheme, the solution injected in step B is heparin-saline.
As the further improvement of technique scheme, also comprise step e: injected and joint outside dialysis catheter has been carried out disinfection and closes afterwards.
The present invention provides again a kind of flusher applying said method, comprise stack shell, push rod and plug, described stack shell is that hollow is arranged, the front end of described stack shell is provided with female Luer, described push rod is inserted in stack shell, and described stack shell is provided with boss, and described boss is provided with through hole, the front end of described push rod is provided with piston, and described piston is connected with the inner wall sealing of stack shell; Through hole seals by described plug.
As the further improvement of technique scheme, described stack shell is provided with handle, and described handle is provided with the front end of stack shell.
As the further improvement of technique scheme, described female Luer, boss and handle are all one-body molded with stack shell.
As the further improvement of technique scheme, described handle and push rod are equipped with anti-slip veins.
As the further improvement of technique scheme, the rear end of described stack shell is provided with back-off.
The invention has the beneficial effects as follows: the present invention is by an interface reserved on conduit, then by the flusher of a syringe-like, solution is injected on conduit, utilize solution to be melted by the thrombosis in conduit, avoid the trouble of patient's Long-term taking medicine, reduce the discomfort of patient.And flusher structure provided by the invention is simple, easy to use.The present invention is used for the flushing of hemodialysis catheter.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present invention, instead of whole embodiment, and those skilled in the art, under the prerequisite not paying creative work, can also obtain other designs and accompanying drawing according to these accompanying drawings.
Fig. 1 is flusher explosive view of the present invention;
Fig. 2 is flusher top view of the present invention.
Detailed description of the invention
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present invention, concrete structure and generation, to understand object of the present invention, characteristic sum effect fully.Obviously; described embodiment is a part of embodiment of the present invention, instead of whole embodiment, based on embodiments of the invention; other embodiments that those skilled in the art obtains under the prerequisite not paying creative work, all belong to the scope of protection of the invention.In addition, all connection/annexations mentioned in literary composition, not singly refer to that component directly connects, and refer to and according to concrete performance, can connect auxiliary by adding or reducing, and form more excellent draw bail.Each technical characteristic in the invention, can combination of interactions under the prerequisite of not conflicting conflict.
A kind of hemodialysis catheter purging method, comprises the following steps: A, on dialysis catheter, be provided with joint; B, solution is injected in flusher; C, flusher and flush-through connection to be tightly connected; D, the solution in flusher to be injected in dialysis catheter.Described joint is arranged on dialysis catheter revealed section, and joint has a sealing device when not using.
Be further used as preferred embodiment, described joint is standard luer fittings.Adopt female Luer can improve the versatility of dialysis catheter.
Be further used as preferred embodiment, the solution injected in step B is heparin-saline.Because heparin-saline has certain anticoagulant effect, the thrombosis formed in conduit can be melted flushing and enter in human body, heparin-saline can provide the nutrition of needed by human body simultaneously.Also for human body provides desired nutritional while solving hemodialysis catheter residual blood formation thrombosis problem, play double effects.
Be further used as preferred embodiment, also comprise step e: injected and joint outside dialysis catheter has been carried out disinfection and closes afterwards.
With reference to Fig. 1 ~ Fig. 2, the present invention provides again a kind of flusher applying said method, comprise stack shell 1, push rod 2 and plug 3, described stack shell 1 is hollow setting, and the front end of described stack shell 1 is provided with female Luer 11, and described push rod 2 is inserted in stack shell 1, described stack shell 1 is provided with boss 12, described boss 12 is provided with through hole, and the front end of described push rod 2 is provided with piston 21, and described piston 21 is connected with the inner wall sealing of stack shell 1; Through hole 12 seals by described plug 3.When using, first pierce through plug by a syringe, then solution is injected in stack shell by through hole, then with push rod, the solution in stack shell is driven in conduit by female Luer, completes the cleaning to hemodialysis catheter.The plug that the present invention uses is medical rubber stopper, and after acupuncture is extracted, energy self-closed pin mouth, avoids antibacterial to be entered in stack shell by pin mouth.
Be further used as preferred embodiment, described stack shell 1 is provided with handle 13, and described handle 13 is provided with the front end of stack shell 1.Due to when solution is driven in conduit from stack shell, needs larger thrust to go to promote push rod, can person easy to use have an effect so be provided with handle on stack shell.
Be further used as preferred embodiment, described female Luer 11, boss 12 are all one-body molded with stack shell 1 with handle 13.
Be further used as preferred embodiment, described handle 13 and push rod 2 are equipped with anti-slip veins.Anti-slip veins can avoid user to cause flusher landing when having an effect.
Be further used as preferred embodiment, the rear end of described stack shell 1 is provided with back-off.By arranging back-off, can prevent from departing from stack shell at push rod toward push rod when post-tensioning.
Above better embodiment of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent modification or replacement are all included in the application's claim limited range.
