The port system, developed from fluid mechanics
Implantable, venous, CT-compatible port.

The most effective solution for long-term vascular access from specialists. In order to achieve optimal cleansing and flow characteristics, we have intensively studied fluid mechanics during the development of the Nu-Flow^®chamber. Through the optimized port chamber geometry, we create turbine-like flow dynamics.

That this is also measurable can be seen here

The transparent septum also makes it possible to see into the chamber during implantation to monitor venting and flushing of the port. The tissue compatible titanium is CT/MRI compatible.

Port chamber
The elliptical chamber associated with the tangential outlet improves flow dynamics and reduces the risk of premature occlusion.

Identification
The NuPort^®-CT port is characterized by the special heart shape and the hexagonal septum opening. This is also easily recognizable in the X-ray image. Furthermore, the heart shape supports the blunt preparation of the port pocket during implantation.

Connection
The connection mechanism enables safe connection of the catheter to the port base via audible and tactile feedback. These two detection functions ensure that the connection is properly secure.

Localization
The raised edge of the NuPort^®-CT makes it easy to palpate the port and locate the septum for infusion or CT application.

Flow theory

Fluid dynamics is the science of the physical behavior of fluids. Ludwig Prandtl created the theoretical foundations of fluid mechanics at the beginning of the last century in the technical department of the Physics Institute of the University of Göttingen. It was popularly called the "Lubricating Oil Faculty".

Fluid Mechanics

The laws of physics are the basis for why airplanes fly and why port housings from PHS Medical look a little different than you may be used to from other port catheters.

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

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%
