Description
Technical field
The utility model is related to the field of medical instrument technology, specifically provide a kind of blunt needle puncture measuring instrument.
Background technology
Clinically the piercing method of internal arteriovenous fistula has three kinds of field method, rope ladder method and buttonhole method at present.US Renal base
It is the first choice of puncture of internal arteriovenous fistula that gold meeting vascular access clinical guidelines, which recommend buttonhole puncturing method,.And buttonhole puncturing method requires to continue
Consistency puncture, i.e. three biconditional operations：It is all same entry point, same needle angle, same depth of needle to puncture every time,
This is the key that form buttonhole puncturing tunnel.The classical way of buttonhole puncturing method is to fix an experienced nurse to wear
Thorn, until buttonhole maturation, that is, hypodermic tunnel formation.Other puncture persons must also fully comply with the gimmick of tunnel former,
Otherwise it will be unable to the blood vessel access for making blunt needle can smoothly enter into tunnel.
In haemodialysis, it is necessary to carry out puncture of internal arteriovenous fistula to establish vascular access.Buttonhole puncturing method has its uniqueness
Advantage can mitigate pain, improve puncture success rate, reduce the complication such as aneurysm and hemadostewnosis and promoted.But buttonhole
Puncture method requires puncture technique high, it is desirable that and it is identical with inserting needle direction into pin position, needle angle, depth of needle every time,
However, at present in medical care precess, due to a lack of corresponding tool, to can not be into pin position, needle angle, depth of needle and inserting needle
Direction etc. is accurately measured, therefore nurse is hemodialysis patients when carrying out puncture of internal arteriovenous fistula, takes blind wear or experience more
Formula punctures, thus puncture path easily shifts, and has not only increased Principle of Pain, but also influence puncture success rate.
In view of this, special propose the utility model.
