Abstract: Intravenous catheter system includes a housing and a guidewire completely disposed within the housing. The system can also include a guide wheel disposed in the housing and operable to rotate about a first axle. The guide wheel can include an inner surface configured to engage the guidewire and move the guidewire. Additionally, the system can include a support wheel operable to engage the guidewire opposite the guide wheel. The support wheel can rotate about a second axle.

Abstract: An intravenous catheter system including a housing, a catheter, and a guide wheel rotatably disposed in the housing and manually engageable by the user. The intravenous catheter system may also include a guidewire contained within the housing and moveable by the guide wheel into and through the catheter with roation of the guide wheel with one finger, and push off tab. The intravenous catheter system may be configured such that once the guidewire is in a vein of a body, the user may use the same finger to advance the catheter by use of the push off tab A blood flash chamber can be incorporated into the housing of the system, method or device to indicate engagement between the catheter and the vein of the patient, and indicate the timing of the use of the wheel to move the guidewire.

Abstract: A built-in front wheel with a guidewire inside that can be advanced easily with one finger (usually the index finger, but variations are allowed based on preference). Once the guidewire is in the vein, the user can then use his/her same finger to advance the plastic catheter by use of a push off tab. A built-in all-in-one IV catheter system that has a front wheel in the usual grip position that allows for guidewire advancement while using IV catheters. A blood flash chamber can be incorporated into the system, method or device to indicate engagement between the catheter and the vein of the patient, and indicate the timing of the use of the wheel to move the guidewire.
