ABSTRACT:
A combination catheter venting and urine sample collecting unit comprises a hollow open-ended body having an outlet and adapted to receive and communicate with a conduit extending to a urine collecting reservoir and an inlet adapted to receive and communicate with a catheter extending to the bladder. The body further has a urine collection needle-receiving port and a number of circumferentially spaced venting apertures spaced longitudinally of the said needle-receiving port. A strip of bacteria and liquid impermeable, and air-permeable filtering material is positioned in liquid-sealing relation beneath the venting apertures. The filtering material is carried on the outside of an open-ended support tube having circumferentially spaced apertures in alignment with said venting apertures. The support tube is enveloped by said body which is preferably molded about the tube. The body has a continuous outer annular indented wall surface upon which the needle-receiving port opens. A self-sealing band of rubber-like material is stretched and supported on the indented wall surface to making a liquid and air sealing relationship with the defining walls of the needle-receiving port.
