Description

Scab removal assembly for dialysis and puncture needle having same

technical field

The utility model belongs to the technical field of medical appliances, in particular to a scab-removing component for dialysis and a puncture needle with the same.

Background technique

At present, many uremia patients adopt the blunt needle buttonhole puncture method in the dialysis treatment. The blunt needle buttonhole puncture method is an arteriovenous fistula puncture method advocated in recent years, which means that each puncture is performed by the same nurse at the same needle point, the same angle, and the same needle depth to form a subcutaneous tunnel, that is, "Buttonhole" is a method of puncturing along the tunnel by changing the sharp needle to a blunt needle after the tunnel is formed. The buttonhole method has the advantages of reducing the pain of patients, reducing the occurrence of autologous arteriovenous fistula aneurysms, prolonging the service life of autologous arteriovenous fistula, and being easy for nurses to puncture, so it is more widely used in clinical practice.

When using the blunt needle buttonhole puncture method, it is mainly divided into four steps: the first step is to peel off the scab; after the skin is disinfected, the blood scab at the puncture point is peeled off; Use the internal fistula to puncture the blunt needle into the needle puncture point; the third step is to twist the needle into the needle. The fourth part, the puncture was successful and properly fixed.

Among them, the first step of scab removal is the key to the whole process. The traditional operation method is to thoroughly clean up the bleeding at the puncture point before blunt needle puncture. If blood scab has formed, use a No. 5 or No. 7 small needle tip to lightly pick the scab, and then use a sterile cotton swab to disinfect again. However, this method has the following disadvantages:

On the one hand, the tip of the small needle is sharp, and it is easy to puncture the puncture port and cause bleeding when removing the scab, which may cause complications such as autologous arteriovenous flaccidity infection and autologous arteriovenous flaccidity dysfunction.

On the other hand, after the small needle lifts the scab, the edge of the scab often adheres to the surrounding skin, making it difficult to remove the scab completely. The process of repeatedly stirring the scab with the needle tip increases the pain of the patient and affects the puncture efficiency.
