초록 ▼

The intravenous catheter insertion apparatus has a catheter integral with a pre-slit injection site, a blunt cannula adapted for piercing the septum of the pre-slit injection site, and a tube slidably housing a needle. In a preferred embodiment, the needle tube and blunt cannula are integral with each other. In use, the needle is extended through the aligned bores of the catheter, injection site, and blunt cannula, leaving a portion of the needle tip projecting from the end of the catheter in order to insert the catheter into the patient's vein through venipuncture. The needle is withdrawn, the needle slide locking in the tube housing after use in order to prevent accidental needle puncture wounds. The blunt cannula is also removable, leaving the septum of the injection site sealed to prevent back flow or spurting of blood from the catheter. In an alternate embodiment, a T-connector having a pre-slit septum may be used in lieu of the of the injection site.

[ I claim:] [1.]1. An intravenous catheter insertion apparatus for insertion of an intravenous catheter into the vein of a patient, comprising:a) a catheter having a hub and a cannula adapted for insertion into a vein of a patient, the hub and the cannula having a bore defined therein;b) a pre-slit injection site having a cylindrical housing defining a chamber and a fluid flow tube, the chamber and the fluid flow tube defining a bore, the fluid flow tube being adapted for insertion into the hub of said catheter so that the bore defined in the pre-slit injection site and the bore defined by the catheter are registered, the housing being connected to said catheter, the housing having an annular groove defined about its circumference, the housing including a flexible and resilient septum having a slit defined therein, the septum forming a cap for the chamber, said catheter and the pre-slit injection site being integral with each other;c) a blunt cannula having a hollow, cylindrical body and a penetrating tube defining a bore, the penetrating tube being adapted for penetrating the slit defined in the septum of said pre-slit injection site in order to register the bore defined in the blunt cannula with the bores defined in said pre-slit injection site and said catheter; andd) a needle having a tip and having a length sufficient to extend through the bores defined in said catheter, said pre-slit injection site, and said blunt cannula, the bores being registered, the needle being slidably housed in a tube having an outlet tube adapted for engaging the hollow, cylindrical body of said blunt cannula, the tip of the needle projecting beyond an end of the catheter in order to penetrate a vein of a patient.
