The port systems with the measurable difference

The port chambers without compromise

Advantages of PHS port systems: reduced risk of infection or occlusion, safe, economical

In the corners of port chambers of conventional standard ports, depositions of blood clots and drug residues can form. These often cause infection or occlusion (blockage) of the port system.

To minimize these risks, the PHS NuPort^® systems have a significantly improved patented chamber geometry. The innovative elliptical inner chamber and the tangential outlet in the Nu-Flow^® chambers significantly reduce the risk of these depositions due to their improved flushing characteristics.

Only 70% of the flushing volume is required for residue-free purging of the port chamber compared to a conventional standard port.

"When it comes to infection of the port cavity, the design of the chamber plays a key role: the more sharp edges there are in the port cavity, the greater the risk of deposition of blood components, which in turn provide a good breeding ground for germs of all kinds."Source: Haindl H., Müller H., Schmoll E. (eds) 1993,

The measurable difference

In the FDA guidelines for the approval of ports, a defined measurement setup* is described, the so-called "Clearing Index". This indicates how much flushing volume is required to flush out (clean) a port chamber without leaving any residue. This test has also been adopted in the ISO standard for port catheter systems 10555-6**.

This can be used to illustrate the measurable differences between different port designs.

In a study by Norfolk Medical Inc., USA ***, the respective flushing characteristics were compared in a measurement of four different port systems. The difference between the system with a conventional cylindrical port chamber and central catheter outlet and our NuPort^® chamber geometry with tangentially positioned catheter outlet is clear:

Almost 40% more flushing volume is required with a conventional port for residue-free flushing.

The chamber geometry therefore makes the decisive difference in the flushing (cleaning) of port systems. Under certain circumstances, this is precisely the difference that prevents occlusion of the port system.

NuPort^® chamber, significantly improved flushing efficiency

C-Port^® chamber, improved flushing efficiency

Conventional cylindrical port chamber, inferior flushing efficiency

Average values chamber flushing volume*

Port	Port Chamber	Flushing volume difference in percent
NuPort^®-CT	Elliptical tangential outlet	Reference value
C-Port^®-CT	Elliptical central baseline outlet	+ 6.9%
Conventional Port A High Pressure Injection	Cylindrical central outlet	+ 23.3%
Conventional Port B Standard	Cylindrical central outlet	+ 39.5%
