Abstract
A catheter and needle system includes a solid piercing needle, a catheter, and a needle tip enclosure, as well as a method of utilization. The solid needle reduces the possibility of transmitting infectious agents to a user otherwise resulting from accidental needle punctures. The system has two configurations, a first for inserting the assembly into a patient, and a second for withdrawing and disposing of the piercing needle. The catheter has means for receiving, delivering and viewing fluids at the insertion site. The needle and enclosure operate cooperatively to enable medical procedures to be conducted without hinderance, and to automatically cleanse and enclose the piercing portion of the needle upon withdrawal. The system also provides for the safe withdrawal of the needle without the need to disturb the catheter once it is inserted.
