ABSTRACT:
A intravenous catheter device having a biased spring hard needle, disposed in a soft catheter. The biased spring hard needle is held within an elongated hollow barrel wherein the biased spring hard needle is extended past the first end of the soft catheter, and is further disposed in the inside of the soft catheter and further extends past the first end of the elongated hollow barrel wherein the biased spring hard needle is pulled into an almost straight line wherein the second end of the biased spring hard needle is fixed to an end cap at the second end of the elongated hollow barrel. The biased spring hard needle is held within the soft catheter and the elongated hollow barrel by a latch means. When the latch means is disengaged with the biased spring hard needle, the spring section of the biased spring hard needle that is near the second end of the biased spring hard needle instantly withdraws the first end of the biased spring hard needle out of the soft catheter and further withdraws the first end of the biased spring hard needle out of the first end of the elongated hollow barrel wherein the first end of the biased spring hard needle cannot accidentally prick or injury a person thereby preventing an accidental injection of bacteria, virus or other undesirable material into a person.
