The invention of safe dialysis indwelling needles originated from an infection incident of medical staff caused by needle sticks. In order to prevent such incidents from happening again, safe dialysis indwelling needles were developed and put into clinical use. It can not only prevent the patient's internal fistula from being further damaged and increase the service life of the internal fistula, but also increase the patient's actual blood flow and improve the dialysis efficiency. The most important thing is that it can completely avoid needle stick injuries to patients and medical staff.
Many patients are asking if there is a device like an infusion indwelling needle that can reduce the frequency of punctures and directly reduce the unpleasant painful experience? Many years ago, it was hard to imagine how to make a 16G puncture needle with a large diameter for dialysis into a dialysis indwelling needle? The "needle" of the dialysis indwelling needle is here!
However, the application of dialysis catheter puncture in clinical practice is limited by medical expenses and is not very widespread. Dialysis catheters are not suitable for long-term retention. Most centers only adopt the principle of single use. Its purpose is to improve the success rate of one-time punctures such as newly activated fistulas and difficult vascular fistulas. Its application in fistula puncture in agitated patients can avoid complications caused by limb activities.
