A port is a reservoir produced of metal, plastic or ceramic with a volume of 0.2 - 0.5 ml. The sense of a port is to guarantee access to the bloodstream without permanently injecting into the veins.
As a matter of principle, a port is implanted under the skin, the connection to the vein or artery being brought about by means of a plastic catheter (silicone or polyurethane). The port or reservoir itself has a self-closing silicone membrane.
This membrane (called a septum) is the access path to the port system.
With specific, non-coring port cannulas, the reservoir (port chamber) is punctured through the membrane in such a way that the medication or infusion liquid can subsequently enter the body through the catheter attached to it.
These products have already been introduced in Germany and have proven their worth in clinical use for a number of years.
medfein has four different ports in its programme, three of them being of titanium, one is made of plastic.
Vortex Port (Titanium)
NuPort CT(Titanium, for high pressure infusions)
C-Port CT (Plastic, for high pressure infusions)
The differences in price between these ports are based on the difference in complication of production technique in the design of the port chambers.
The Vortex Port and NuPort have specially designed round port chambers.
Deposits of blood clots and residue of medication can lead to a blockage of the port. In order to remove or prevent this blockage, additional medications must be used (Thrombolytics, e.g. Urokinase).
The round chamber of the Vortex and NuPort leads to a considerable improvement of the flow dynamics, which stops blockages and distinctly limits or even rules out the administration of the aforementioned medication (to dissolve the blockages).
The ports are supplied with catheters of various diameters and with or without introducer set.
In order to insert the catheter into the vessel, the direct path is often selected in venous application, i.e. the vein is opened with a cut and the catheter pushed into the vein through the opening.
Depending on the indication and the vessel (artery = higher blood pressure than vein), the use of an introducer set to minimise the injury to the vessel is recommended.
The introducer set is available as a complete kit together with the ports as well as individually packed.
Port infusion sets
This is a needle which is hollow on the inside and has a right-angled bend.
It has an infusion line about 10 cm in length.
Unlike conventional cannulas, which are used for taking blood, for example, the port cannulas have a special grinding at their tip, which does not damage the septum of the ports when it is inserted.
This is why they are also called "non-coring needles"
As a rule, these port cannulas have small wings on both sides (which is why these cannulas are also sometimes called butterfly cannulas), with which the fixing to the skin is then done.
As described above, the port is underneath the skin, i.e. it is not visible, but has to be felt by the doctor or the nurse.
The port cannula must be inserted through the skin, the tissue and the septum, in order to ensure that the medication can enter the port chamber and from there continue to flow through the catheter into the patient's vein or artery.
The model designation for the port cannula with infusion line is Lifeport Infusions Set and we distinguish between two versions (with and without Y-site).
The further distinctions refer to the diameters of the needles (measured in gauge) and the length (measured in inch or mm).
The port cannulas without an infusion line are needed for short-term administration of
They are available in a straight version.
The further distinctions refer to the diameter and the length of the needle.
