An IV catheter introducer having an elastomeric grommet disposed between the housing and the IV catheter assembly that helps avoid unintentional separation of IV catheter assembly from the housing during shipping and handling prior to use, that acts as a needle guide, that helps align the housing and IV catheter assembly coaxially, that indicates that top side of the catheter introducer, that provides proper rotational alignment between the grommet and housing, that wipes blood off the needle during withdrawal of the needle from the catheter assembly and grommet, that impedes blood flow out of the catheter hub after needle withdrawal, and that assists the user in separating the housing from the IV catheter assembly following insertion of the catheter and withdrawal of the needle.
An IV catheter introducer comprising in coaxial alignment a housing having a needle holder assembly seated therein with a needle projecting forwardly from the housing, a plunger assembly having a plunger tube slidably insertable into the housing, an IV catheter assembly having a flexible catheter attached to a rearwardly facing tubular hub, an elastomeric grommet disposed between the housing and hub, and a removable cover disposed over part of the needle and catheter prior to use of the IV catheter introducer;
An IV catheter introducer having with a retractable needle, the introducer comprising a tubular housing, a needle holder assembly having a needle holder seated inside the housing and a needle attached in fixed longitudinal relation to the tubular body, a retraction spring seated in an annular space between the housing and the tubular body of the needle holder assembly, a plunger assembly having a plunger tube insertable into the housing and engageable with the needle holder inside the housing, the plunger assembly and housing cooperating to maintain the retraction spring in compression prior to retraction, an IV catheter assembly having a flexible catheter attached to a hub, an elastomeric grommet disposed between the housing and the IV catheter assembly, and a removable cover disposed over part of the needle and catheter prior to use of the IV catheter introducer.
