TyTek Medical’s 14 gauge TPAK chest decompression needle is 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. Our 14 gauge x 3.25" TPAK chest decompression needle is a compact, reliable solution for treating a tension pneumothorax. Shock resistant case ensures the needle/catheter is secure upon deployment, and the capless flash chamber gives instant confirmation of needle placement in prehospital needle thoracostomy. TPAK comes in a rugged case, with a textured, easy-open hex cap.
