With the Internet providing easy access to blowgun instructions, such cases may become more common in the future, the researchers said.Īs shown in this case, teens do not always tell the truth, which can complicate receiving a correct diagnosis. A dart could puncture a hole in the airway or lungs, or injure the voice box.īecause of their risks, blowguns should probably not be used by children or teens, Jatana said. Anytime an object is inhaled and trapped in the airway, it can be a life-threatening problem, he said. In both cases, the darts were removed without complications.īut the three boys were all very fortunate not to have any serious complications, Jatana told LiveScience. Over the next three months, the doctors saw two more cases of teen boys (ages 14 and 15) who inhaled darts from homemade blowguns. Despite inhaling a sharp object, the boy was not harmed by the ordeal, according to the case report. The boy underwent a nonsurgical procedure in which a tube is inserted down the throat to view objects in the airway, and the dart was removed. In the future, chronograph results will be updated reflecting higher band pre-load tensions as well as varying band materials.When a child inhales deeply (to produce a forceful breath to propel the dart forward), their vocal chords open fully, which makes it easier for objects to enter their airway, Jatana said. The surgical tubing bands used on the guns we tested are admittedly conservatively tensioned in order to reduce wear and tear on the gun's mechanisms. However, elastic band material composition and differences in band tension pre-load may account for this difference. Our preliminary chronograph testing has yielded a significantly lower FPS figure for the MX-7. The manufacturer's advertised FPS (Feet Per Second) rating for the MX-7 rifle was 720 FPS. Preliminary chronograph data for the Mega-Dart guns The needlelike, 4-inch-long ammunition for Mega Dart's MX-7 dart gun will be replaced with rubber ammunition "that can't penetrate anything," John Turner said in a telephone interview from his office in El Paso. Metal darts that police say can pierce bulletproof vests were pulled off the market, the chairman of the company that makes them said. At this instant the elastic bands will rapidly contract driving the cocking handle & piston rod/piston assembly forward inside the compression tube producing a burst of air that forcefully ejects the dart out the front of the barrel and toward the target. Upon firing the Mega-Dart one will sense the gun rise and exhibit significant reverse recoil. One aims the rifle by looking through the sighting tube mounted on top of the gun. This stretches the pair of latex elastic bands/tubing that encircle the cocking handle which is attached to the piston rod/piston assembly. Pull back on the cocking handle at the rear of the gun until it locks in place. To use the gun, retract the rifle's bolt and insert a dart then close/lock the bolt. At this time (June 2011) the Mega-Dart blowguns are no longer in production and therefore are only available on the used market. The guns were offered for sale in retail stores, catalog outlets, and through ads placed in various magazines. A patent application was filed in August of 1985 and was subsequently granted in December of 1986. Turner and the guns were manufactured by Wells Fargo Manufacturing Co. was founded in El Paso, TX by the gun's inventor John E.
The Mega-Dart MX-7 rifle and MX-5 pistol are spring piston powered airguns that fire conventional.
