Intraosseous Access Training Device

Intraosseous Access Training Device -------------------------------------------------- I am deeply inspired by the innovative idea behind OpenTibia (Intraosseous Access Simulator) created by Brooks Dillahunty. A simulator that allows intraosseous access to be practiced easily and affordably. 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 then punctures through an exchangeable bone window. Syringe Form Unusual in Germany --------------------------------------------- However, the 20ml disposable syringes used in my area have an eccentric Luer connection and do not fit into the OpenTibia model which requires a central connection. The 20ml disposable syringes we commonly use have an eccentric Luer connection that does not fit into the OpenTibia model based on 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 appears as if it is not a right tibia, but rather the left tibia which has been rotated by about 80 degrees medially. The puncture area now lying on top is actually the facies lateralis tibiae, which normally attaches 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 do not 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 with any manufacturer of intraosseous access devices. The simulator presented here is not a medical device and has not been 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. But those with central connections should also fit. As bone marrow is very well suited to liquid barbecue sauce. Because of the low production costs, every trainee can get their own fresh puncture site cover. The model can 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.
