Definitions
- the present invention is addressed to reducing and eliminating this risk by means of a novel arrangement at the Y-site as more fully hereinafter described. It is believed that this invention makes an important contribution to the art and will be widely adopted by health care institutions and personnel.
- an intravenous administration set having a Y-site, tubing extending therefrom having a patient-indwelling terminus, a second length of tubing extending from the Y-site with a terminal means for connection to a first source of intravenous solution, said Y-site having an inlet port adapted to be punctured by the scarf of a cannula for introduction of a second intravenous solution from a container or a parenteral injection by means of a hypodermic syringe; and
- a protective device positioned around a cannula which is adapted to communicate the contents of the intravenous solution container or hypodermic syringe with the tubing leading to the patient and adapted to abut the exterior of said Y-site, said protective device having a generally cylindrical portion surrounding the cannula over its length and extending beyond the end of the scarf of the needle, said cylindrical portion having at least one, and preferably two diametrically disposed cutouts, each adapted to snugly receive by lateral reception the tubing of the intravenous set while said scarf has punctured the said inlet port, said cannula being carried by a boss;
- FIG. 6 is an alternative embodiment of the protective device of this invention, in side, partial sectional view, which is adapted to serve as a connection between a tubing leading to the set source of intravenous solution and the Y-site of an intravenous administration set.
- the Y-site has an injection site 34 having an imperforate closure or diaphragm which is pierced or punctured by scarf 22 concurrently with the tubular portion 32 being received in one or the other of said cutouts 30.
