Description
Technical Field
The invention belongs to the field of medical instruments, and particularly relates to a hemodialysis retention buttonhole needle.
Background
In clinical work, hemodialysis is an important method for treating diseases such as acute and chronic renal failure, about 20% of dialysis patients need hospitalization due to vascular access complications, repeated puncture of vascular access is unavoidable, mechanical damage to the vascular wall is caused by puncture, a plurality of pathophysiological changes are caused to the vascular wall, and common complications of puncture are as follows: bleeding, puncture failure, hematoma, aneurysm, thrombus, stenosis, etc., and often cause internal fistula to lose work, the vascular access is a "life line" for maintaining a hemodialysis patient, most hemodialysis patients adopt an autologous arteriovenous internal fistula as a long-term vascular access, therefore, the quality of the arteriovenous internal fistula maintenance directly affects the service life of the vascular access, and the dialysis quality and the life quality of the patient, and the puncture method mainly comprises: the regional method, the rope ladder method and the buttonhole method have the advantages of high puncture success rate, light pain, willingness to accept by patients, low requirement on blood vessels and the like, and the rope ladder method has the advantages of evenly distributed puncture points, contribution to blood vessel repair, even blood vessel expansion, difficult formation of hemangioma and the like when compared with the local repeated puncture, serious local injury, easy occurrence of stenosis, high generation of aneurysms and the like, but the method has the advantages of high puncture difficulty, high puncture failure rate, obvious pain, high requirement on blood vessel conditions and the like, the buttonhole method performs fixed point puncture, has small tissue injury, high puncture success rate, difficult occurrence of complications and the like, and the patient has light pain and willingness to accept, and the buttonhole puncture method is an internationally recognized puncture method of internal fistula at present, namely, the buttonhole puncture method adopts the same needle insertion point, needle insertion angle and needle insertion depth every time, the percutaneous puncture needle is required to be repeatedly punctured by the same nurse for about 6-8 times to form a subcutaneous tunnel, the blood crust at the tunnel portal is a buttonhole, the blood crust at the buttonhole is gently removed after skin is disinfected in the future, the blunt needle is pushed slowly from the buttonhole, the blood vessel can be accessed along the tunnel, the complication rate of the internal fistula punctured by the buttonhole method is obviously lower than that of the regional puncture method, the requirement on the length of the internal fistula blood vessel is low, the percutaneous puncture needle is suitable for all patients with blood permeation, especially for the patients with insufficient blood vessel resources, but because the buttonhole puncture has high technical requirement on nurses, the nurse has high pressure, the blood crust is unwilling to be received before the buttonhole puncture, the time is too long, the receiving degree of nurses is influenced, wet dressing and disinfection scab removing are required before the buttonhole puncture is implemented, the patients are required to reach the blood permeation chamber in advance and the time is prolonged, the operation is more complicated, the expense is higher, in addition, the buttonhole puncture easily increases the risk of infection, and these all make the patient be unwilling to accept the buttonhole puncture, and in addition, because disposable hemodialysis needle point is sharp, on the one hand punctures the blood vessel easily in the puncture process, on the other hand, the steel needle is in the tube drawing process, and the easy stabbing caregivers of hand, at present, though there is also the stay needle of dialysis usefulness, keep somewhere the needle and break easily, have the risk of deviating from the hemorrhage, this also makes the stay needle of dialysis use unable wide-ranging application.
