Pleural puncture needle TyTek

Veressblunt

The TyTek PneumoDart was designed to overcome the shortfalls of the flexible catheter. The catheter was never designed for this purpose and as an IV catheter, it is designed to become soft and pliable in the body. This fact makes it only a very temporary solution for tension pneumothorax, one which will fail shortly after insertion as we have seen many times on the battlefield requiring multiple needles with an increase in misplacement and damage to the tissues. Placement verification of the flexible catheter in the chest could not truly be delineated as there is no indicator other than the potential audible rush of air. On the ground, in the air, or in combat this is very difficult to appreciate. Even when one is successful, there is no indicator to show placement and to ensure proper depth to maintain for continuous venting of the pneumothorax. We designed our product along with a similar design of a Veress needle used in the operating room for laparoscopic procedures. If you google a Veress needle, you will see the inner cannula retracts to expose the needle. The needle inserts through the tissue and deploys the blunt tip cannula once the needle is through. Our needle has a blue plastic indicator that moves up and down with the cannula. Once our needle penetrates, the cannula will deploy and the blue indicator will click in the down position to show the operator that they are in the pleural cavity. Now the needle can be secured in place at the proper depth for transport.
