AV fistula catheter

Vascular access in dialysis – a sensitive, risky issue

Each dialysis patient spends up to 624 hours a year at the renal care center for their life-saving treatment. During this time, their fistula is cannulated about 300 times (assumption: three treatments per week). Every dialysis session can be particularly stressful, both for the patient but also for the nursing staff, because this complex procedure is never routine.

Needlestick injuries can happen to anyone at any time. They can be caused by patient-related factors, such as anxious or restless patients, an inadvertent bump from a passing colleague, or concealed sharps.

Diacan® Flex

Safety mechanism can prevent needlestick injuries

Diacan® Flex is equipped with an integrated protective mechanism that automatically covers the needle tip immediately after withdrawal, as well as a built-in blood control valve that help prevent blood leakage when the tube is removed.

More patient comfort

Fistula catheters with plastic capillary instead of steel needles

For some patients, it is just a little sting, for others it remains a difficult moment during every treatment.

It only takes a moment to puncture the fistula, but this usually happens about 300 times a year. Therefore, it is very important to keep both the psychological and physical stress as low as possible.

Diacan Flex was developed to increase patient comfort and reduce the risk of vascular injury. After the catheter is placed, the needle is removed and only the plastic capillary stays in the fistula. Its soft material and holes on the side help to protect the vein. Compared to conventional steel needles, the risk of perforation and infiltration can be reduced, even if the patient moves the arm.
