The 14 gauge TPAK from TyTek Medical is a chest decompression needle in the recommended 3.25" length for treating a tension pneumothorax. You can't count on a standard IV catheter to needle a chest deeply enough in needle thoracostomy. The TPAK is reliable solution with a shock-resistant case ensuring the needle/catheter is secure upon deployment for continuous relief. The capless flash chamber gives instant confirmation of needle placement in prehospital needle thoracostomy. The TPAK comes in a rugged case with a textured, easy-open hex cap. Its compact and convenient size makes it suitable for maximum portability.
