Intraosseous Access Training Device
I am very inspired by the idea behind OpenTibia (Intraosseous Access Simulator) published by Brooks Dillahunty. A simulator that allows intraosseous access to be practiced easily and inexpensively. https://www.thingiverse.com/thing:2750234
A disposable syringe filled with imitation bone marrow is inserted into a 3D-printed model of a proximal tibia. The plastic syringe is then punctured through an exchangeable bone window.
Syringe form unusual in Germany
However, the 20ml disposable syringes used in my area of activity have an eccentric Luer connection and do not fit into the OpenTibia model which requires a central connection.

Therefore I also downloaded the anatomical tibia model from Steph Piper ( https://www.thingiverse.com/thing:1030467) and designed my own IO training device.
OpenTibia not anatomically correct?
I noticed that the model of Brooks Dillahunty does not seem to be anatomically correct. If you compare the models, it looks as if it is not a right tibia, but the model of the left tibia which is rotated by about 80 degrees medially, so that the puncture area now lying on top is actually the facies lateralis tibiae, which is normally attached to the musculus tibialis anterior. Therefore you can also see the facies articularis fibularis on the head of the tibia, which otherwise lies dorsally and laterally and to which the fibula is attached.
I don't find this ideal for a teaching model, even though it hardly influences the success of the training. In my model, I used the tibia in its correct position and left the joint surfaces on the head of the tibia so that the practitioner can grasp a better relation to the knee joint.
Disclaimer:
I have no relationship to a manufacturer of any interosseous access devices. The simulator presented here is not a medical device and is not approved for use with any medical device. Attention! It cannot be excluded that the use of these simulators may cause injury to the user or damage to a medical device.
Application:
The model works excellently with our standard BD Discardit II 20ml or BBraun Injekt, Luer, eccentric, 20ml disposable syringes closed with a combi-stopper.
As bone marrow is very well suited relatively liquid barbecue sauce.
Because of the low production costs, every trainee can get his own fresh puncture site cover.
The model can, for example, be covered with pieces of a silicone mat, as sold as a baking tray, to make the palpation above the tibia relatively realistic.
I would be very pleased about feedback.
