Delta Med arterial catheters

Arterial catheters are devices used mainly in the intensive care, sub-intensive care and operating room settings.

The introduction of a cannula or catheter into a palpable artery allows continuous measurement of blood pressure (systolic, mean, and diastolic) and rapid blood sampling for blood gas analysis.

Using devices that are effective, safe, and easy to use makes the procedures easier and reduces the risk of infection or accidental puncture. In this article, let's take a look at the main features and benefits of Delta Med arterial catheters.

Delta Med arterial catheters: FEP or PUR, depending on your needs

Delta Med Arterial Catheters are available, depending on different clinical needs, as Delta Long Cannula (in sizes 3-4 French up to 10 cm long) and as Delta Arterial Cath (in sizes 18 and 20 Gauge, both 4.5 cm long).

Both catheters can be made of FEP or PUR.

The FEP catheter allows for more precise and accurate blood pressure measurements, while the PUR material, because no kinking fetures, can be a good solution for radial artery cannulation.

The Delta Arterial Cath is equipped with a safety mechanism to prevent accidental punctures by the healthcare professional, while a closing valve (red in colour) indicates when it is open or closed.

Easy to use and with an ergonomic handle, the catheter comes with a chamber of visualization for better control of blood return. The needle is made in stainless.

The positioning of the long arterial cannulae can be performed by direct technique or Seldinger technique (for difficult positioning it is also possible to use the MST - Modified Seldinger Technique technique).

Delta Med arterial catheters: safe and easy to use

An arterial catheter is usually inserted into a radial or femoral artery, but access can also be through the ulnar, pedidial, axillary or brachial artery.

The ease of use of Delta Med arterial catheters is a real added value of this device.

After taking maximum barrier precautions, preparing the insertion site, and performing the Allen test to assess blood flow to the hand and fingers, the catheter insertion procedure can begin.

In the case of the Delta Arterial Cath, once the needle cover has been removed, the following steps should be followed:

  • access a peripheral artery;
  • observe blood return in the flashback chamber;
  • advance the catheter over the needle over into the artery;
  • stabilize the catheter;
  • pull the needle out from the catheter until a "click" is heard, indicating that the safety shield of the needle is activated;
  • quickly close the red valve, turning it clockwise, to stop the blood flow;
  • extract the needle (before final removal of the needle from the catheter body, the needle protection system is automatically activated passively - eliminating the risk of accidental punctures.

Clearly, in the choice of the access site, several factors should be evaluated in addition to comfort and safety: antisepsis management, presence of other catheters, presence of any anatomical deformations and risk of mechanical complications (eg, bleeding).
