I spent a productive day today at work doing some arts and crafts in between calls. Specifically I tried to recreate the training larynx I played with at the SMACC Gold airway workshop. I think these were made by Scott Weingart and/or Rich Levitan, but I’m not actually sure. I apologise if I have got that wrong.
EDIT: It appears that Chris Bond from SOCMOB may be responsible for the cric trainer. Head over to this page to see his video. Scott also links to a very fancy version built by St George Hospital in Sydney over at EMCrit
I think I did a not bad version of re-inventing the wheel though!
Anyway, here is what I did.
Old wooden arm splint as a base.
Ventilator tubing as the larynx (bag is optional)
1 inch and half inch tape
Wide fabric tape.
Fake skin type stuff.
Wind tape around the tubing to simulate the thyroid bone (1 inch tape) and cricoid (1/2 inch tape.
Wide tape is then used to secure it all to the board and act as skin. Several layers may be required.
I have the placed this thick adhesive foam dressing on top to simulate adipose tissue and skin better.
I’m not sure whether it needs another layer of tape on top or not
And that’s it!
The foam skin layer things are quite expensive so may not be desirable. Multiple layers of brown fabric tape will work, or even the brown plastic tape as it feels a bit more like skin. Obviously it’s not as good as the real thing, but it simulates the tactile sense reasonably well. Surgical cricothyroidotomy is all about the feel so hopefully this helps experience that.
