Abstract
A vented needle with sideport comprising a main body housing having dual input ports at substantially right angles to each other. An integral needle structure having a central aperture therethrough being generally in the same axial alignment as one input port and transversely to the other port. A tubular sleeve around the projecting needle for providing a second fluid flow path externally thereof. The needle preferably has a longitudinal groove therein for increasing the fluid flow along the circumference of the needle. The device is designed so that the needle is longer than the tubular sleeve and, thus, air can be passed therethrough without danger of any air being inputted to the liquid flow of the shorter tubular sleeve liquid flow passageway. A hydrophobic air vent filter preferably is connected to the air input of the device. The method of assembly of this vented needle with side port is also part of this invention.
