The problem: needlestick injuries

More than 2% of all urine samples contain blood.[1]

Needlestick injuries are one of the main causes of infections with hepatitis B and C virus as well as HIV and constitute a great risk to nursing staff.[2] In Germany alone, approx. 500,000 needlestick injuries occur each year.[3] This results in consequential costs of about 30 million euros per year just in Germany.[4]

The solution: KombiKon™

The KombiKon™ urine sampling point allows nursing staff to take urine samples without the use of a needle and thus safely. With the amendment to the technical directive regarding ‘Biologische Arbeitsstoffe im Gesundheitswesen und in der Wohlfahrtspflege’ (‘Biological materials in health care and welfare work’) (TRBA 250), which came into force on 1 August 2006, the duty of employers to prevent needlestick injuries have now been set out in binding terms.

A clinical test has shown that KombiKon™ can be used without the risk of contamination to the urine drainage system for at least ten sample collections.[5] In addition, KombiKon™ is a universal connector suitable for most standard syringes thus rendering expensive special cannulas superfluous.
