IV setup for medical simulation

We use a simple setup with an IV ‘bung’ on the end of a piece of hose to simulate an IV site on our manikins and simulated patients (actors).  The hose assembly is held onto the patient with a piece of ‘tubigrip’ elastic stocking.   If we don’t want an IV in-situ at the beginning of the scenario, the bung is covered by the tubigrip and only uncovered by a confederate when an IV has been established.

It is also possible to attach an IV cannula to the bung and put the tubing over this.  This adds the visual indicator of cannula size (via hub colour) as well as restricting the flow somewhat to give more accurate (i.e. lower) flow rates.

The hose passes under the arm and over the top of the bed to a bucket (5 litre spring water dispenser with a hole in the top) or urine collection bag.  This allows participants to infuse anything (drugs or fluid) during scenarios.

A suggestion was made at a recent NHET-Sim workshop to include the plastic cannula between the bung and the tubing to restrict the flow to more reasonable rates.  You may have to cut off any protruding bits to leave a nice round section for the tube to grip.  It’s a tight fit, glue and/or clamps are not necessary.

The Sims team at the Women’s and Children’s Hospital in Adelaide suggested an improvement to this by using ‘skin’ colored irrigation tubing from the local hardware store (Bunnings).  Various other tubing does work, but silicone is very expensive.  This was about $7.50 AUD for 10 meters.  The adapters can be used to connect the tubing to the collection bucket, but just putting the tube through a hole down into the bottom of the bucket works quite well and you don’t hear the tinkling of water falling into the bucket.
