Description
Technical field
The utility model belongs to a kind of medical instruments field, especially a kind of haemodialysis indwelling buttonhole needle.
Background technique
In clinical position, haemodialysis is to treat the important method of the diseases such as acute or chronic renal failure, dialysis patient
In there are about 20% because vascular access complications need hospitalization, puncture vessel access is inevitable repeatedly, and puncture will cause
Vascular wall mechanical injuries cause vascular wall that some column pathophysiological changes occur, and the common complication of puncture has: bleeding,
Puncture failure, hemotoncus, aneurysm, thrombus, narrow etc., and often result in internal fistula and lose function, vascular access is that maintenance hemodialysis patient is " raw
Order line ", most hemodialysis patients are all made of Autogenous arteriovenous blood vessel internal fistula as long term vascular access, therefore, in arteriovenous
The quality of fistula maintenance directly affects the service life of vascular access and the dialysis quality and life quality of patient, puncture side
Method specifically includes that field method, rope ladder method, buttonhole method, respectively there is its pros and cons, and field method has puncture success rate height, pain relatively light, sick
People is ready to receive, to the low advantage of blood vessel requirement, it is insufficient punctured repeatedly with part, local damage is serious, it is narrow, dynamic to be also easy to produce
Arteries and veins tumor occur it is high, rope ladder method have point of puncture be uniformly distributed, conducive to vascular repair, blood vessel dilatation uniformly, be not easy to form blood vessel
The advantages that tumor, but this method is there are venipuncture difficulty height, puncture failure rate is high, pain is obvious, it is high not to vascular conditions requirement
The advantages that foot, buttonhole method carry out fixed point puncture, and tissue damage is small, and tool puncture success rate is high, are less prone to complication, and patient
Pain is light, is ready to receive, currently, buttonhole puncturing method has been the piercing method of internationally recognized self internal fistula, so-called " buttonhole puncturing
Method ", i.e., puncturing all every time is it is same both to need to accomplish three, and by same using identical entry point, needle angle, depth of needle
Name nurse punctures 6-8 time or so is formationed hypodermic tunnel repeatedly, and as " buttonhole ", carrying out puncturing in the future need to be for the scab of tunnel face
The scab of buttonhole is gently picked after disinfection skin, changes blunt needle and is slowly pushed from buttonhole, blood vessel, buttonhole can be entered along tunnel
The fistula-induced complication incidence that method punctures is significantly lower than region puncture method, while not high to the length requirement of arterial-venous fistula, is suitble to
All hemodialysis patients, the especially inadequate patient of blood vessel resource, still, since buttonhole puncturing is to nurse's technical requirements height, nurse
Pressure is big, is unwilling to receive buttonhole puncturing, and is needed before puncturing except scab, time-consuming too long, also influences the acceptance level of nurse, and right
For patient, soak is carried out before implementing buttonhole puncturing and scab is gone in disinfection, patient is needed to be advanced in blood dialysis room and delay
The machine time, complicated operation, costly, in addition, buttonhole puncturing is easy to increase the danger of infection, these are all reluctant patient
Meaning receives buttonhole puncturing, further, since disposable blood dialysis needle needle point is sharp keen, is on the one hand easy to puncture blood in puncture process
Pipe, on the other hand, steel needle is easy to stab nursing staff during tube drawing, although currently, also having the indwelling of dialysis
Needle, still, remaining needle are easy to fracture, and have the risk of abjection bleeding, the remaining needle of this dialysis also made can not be significantly wide
General application.
Summary of the invention
