Description
Technical field
The present invention relates to the field of medical instrument technology, are specifically related to a kind of haemodialysis internal fistula buttonhole puncturing remaining needle dress
It sets.
Background technique
Haemodialysis (Hemodialysis, HD), abbreviation hemodialysis, popular saying are also referred to as artificial kidney, wash kidney, are most
One of common renal replacement therapies method；Using semi-permeable membrane principle, being removed in blood by disperse, ultrafiltration and convective principles has
Evil substance and excess moisture achieve the purpose that purify blood, correct Water-Electrolyte and acid-base balance；Not according to treatment method
Together, it is divided into Intermittent hemodialysis and Acute renal failure treatment；Other than being applied to chronic kidney hypofunction replacement therapy, also
It is widely used in acute renal failure caused by different reasons, multiple organ failure, severe trauma, acute necrotic pancreatitis, height
Potassium mass formed by blood stasis, hypernatremia, medicine or poisonous substance poisoning etc..To patient symptom is mitigated, extension life cycle has the certain significance, and robs
One of emergency, the effective measures of chronic renal failure.
Internal arteriovenous fistula is the preferred vascular access of haemodialysis, but unavoidably needs puncture vessel repeatedly, and
Puncturing repeatedly will cause vascular wall mechanical injuries, and vascular wall is caused to occur some column pathophysiological changes, puncture it is common
Complication has: bleeding, puncture failure, hemotoncus, aneurysm, thrombus, narrow etc., and often results in internal fistula and lose function, and vascular access is dimension
It holds " lifeline " of dialysis patient, it is logical as long term vascular that most dialysis patients are all made of Autogenous arteriovenous blood vessel internal fistula
Road, therefore, internal arteriovenous fistula maintenance quality directly affect vascular access service life and patient dialysis quality and
Life quality；Puncture of internal arteriovenous fistula method specifically includes that field method, rope ladder method, buttonhole method；Buttonhole method is that each inserting needle uses
Same point of puncture, same angle, same depth, repeated puncture 2 months or so one hypodermic tunnels of formation then use later
Pure pin puncture tunnel is dialysed, and internal fistula is relatively limited to, autologous vein condition difference patient also has higher puncture success rate, together
When can also extend internal fistula service life, the complication such as hemangioma, hemadostewnosis, thrombus are reduced；But since buttonhole puncturing is to shield
Scholar's technical requirements are high, and puncturing all every time is to use identical entry point, needle angle, depth of needle, both need to accomplish that three is same, and
2 months (6-8 times or so form hypodermic tunnel) is punctured by the same nurse repeatedly；It is needed before puncturing simultaneously except scab, it is time-consuming too long,
Soak is carried out before implementing buttonhole puncturing and scab is gone in disinfection, needed patient to be advanced to dialysis center and delayed the machine time, operate
It is complex, costly；In addition, buttonhole puncturing is easy to increase the danger of infection, and if internal fistula surrounding tissue infects, buttonhole puncturing
Buttonhole puncturing point oozing of blood also result in infection；Blunt needle inserting needle difficulty etc. is also not easy to the operation of medical staff when puncture, is based on
The above problem constrains the popularization and application of internal fistula buttonhole puncturing method, and has no the buttonhole puncturing to solve the above problems at present
Puncturing needle special and sting device.
Summary of the invention
In view of the above-mentioned problems existing in the prior art, the present invention provides a kind of haemodialysis internal fistula buttonhole puncturing remaining needles
Device, indwelling arterial-venous fistula after puncture are punctured without being repeated several times, and are convenient for blunt needle inserting needle, while reducing internal fistula surrounding tissue sense
Dye, oozing of blood probability；It is reasonable in design, it is promoted and applied convenient for haemodialysis internal fistula buttonhole puncturing.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions:
A kind of haemodialysis internal fistula buttonhole puncturing indwelling needle device, including indwelling buttonhole, puncture pedestal, puncture needle, sealing liquid
Pipe and blunt needle, indwelling buttonhole is separable to be mounted on and punctures pedestal front end, and puncture needle penetrates and from pedestal rear end is punctured from indwelling
Buttonhole head end is pierced by, and pedestal is punctured after puncture and separates the indwelling of indwelling buttonhole with indwelling buttonhole and is worn by blunt needle from indwelling buttonhole rear end
Thorn；
The ontology of the indwelling buttonhole is absorbable or nonabsorable hollow tube, and surface indicates evenly spaced scale
The diameter of line, the buttonhole head of indwelling buttonhole front end is successively successively decreased to the back-end by front end, and buttonhole pedestal, the buttonhole base are installed in rear end
Seat end is that connecting base and puncture pedestal are detachably connectable, and multilayer buttonhole puncturing film, the buttonhole pedestal are installed in buttonhole pedestal
Wound dressing and sealing paste are installed with the connecting pin of indwelling buttonhole ontology；
The blunt needle front end is arc, and rear end is disk like handle and connect with perfusion tube that blunt needle is more from buttonhole base end
Layer buttonhole puncturing film penetrates, and is pierced by from the buttonhole head of buttonhole pedestal front end；
The hollow cavity of the puncture base interior, side perforation connection dip tube, rear end is for puncture needle connecting base and in
Closed puncture film is installed in cavity road.
Further, the ontology of the indwelling buttonhole is transparent or semitransparent absorbable or nonabsorable medical material,
Border on end with buttonhole pedestal and one layer of Wound dressing is installed, Wound dressing is antiallergy silver-ion antibiotic Wound dressing, and the surface of a wound applies
Material, which is pasted on round or ellipse sealing paste, to be fitted at puncture.
Further, multilayer pellosil sterile polymeric membrane is installed as buttonhole puncturing film in buttonhole pedestal and realizes indwelling button
The sealing of eye, buttonhole puncturing film are no less than 3 layers；
The buttonhole puncturing film innermost layer is bleeding-stopping dressing, and outermost layer is aseptic dressing.
Further, indwelling buttonhole end is buttonhole pedestal, and the connecting base of buttonhole pedestal is equipped with seal cap covering；
The seal cap is calparine cap；
The connecting base of the buttonhole pedestal is connected with puncture pedestal by screw thread.
Further, the mellow and full sheet pedestal in corner is fixed on the buttonhole pedestal, sheet pedestal opens up groove and wraps
Wrap up in one layer of elastic material or gas cell；
The sheet pedestal is fixed by Elastic bandage or other fixing elements with body surface.
Further, the puncture needle is penetrated and is pierced by from indwelling buttonhole head end, puncture needle front end from puncture pedestal rear end
For sharp puncturing head, rear end is to puncture needle handle.
Further, the puncture pedestal side perforation connection dip tube, blunt needle rear end connects perfusion tube.
A kind of application of haemodialysis internal fistula buttonhole puncturing indwelling needle device in the puncture of haemodialysis internal fistula.
Another object of the present invention is to provide a kind of haemodialysis internal fistula buttonhole puncturing external members, including at least one
It states indwelling buttonhole, puncture pedestal, puncture needle, dip tube and the above-mentioned blunt needle aseptic sealed packages of at least ten.
