Abstract

An intravenous catheter system having a retractable needle system and a body system is disclosed. The retractable needle system includes a housing, a needle, a docking feature, and an optional anti-shearing mechanism. The body system includes a body, at least one hub, a catheter connector, at least one plug, a plug recoil mechanism, a locking mechanism, a flash chamber, and a flash window.

Claims

1. An intravenous catheter system, comprising:

a body having an internal volume and a proximal end, the body having an exterior surface;

a plug secured to the body and in fluid communication with the internal volume;

a plurality of fluid channels disposed within the internal volume of the body;

a catheter in fluid connection with the proximal end of the body; and

a layer of adhesive material adhered to the exterior surface of the body and configured to limit movement of the body relative to an injection site on a patient, the adhesive being disposed between the body and the injection site on the patient;

wherein the adhesive creates a bond between the body and the injection site of the patent, which in turn prevents movement of the body; and

wherein the plurality of fluid channels are configured to provide fluid communication between the plug and the catheter.

2. The intravenous catheter system according to claim 1, further comprising:

a translucent flash window integral with the body for allowing visual inspection of the internal volume.
