Intravenous catheter insertion and blood sample devices and method of use
First Claim
1. An apparatus for drawing blood, comprising:
- a housing having an interior volume;
a seal partitioning the interior volume of the housing into a distal interior volume portion and a proximal interior volume portion;
a blood draw port in fluid communication with the distal interior volume portion;
a needle extending through the seal, the needle having a proximal end positioned in the proximal interior volume portion and a distal end extending beyond a distal end of the housing in a first position; and
a guidewire having a proximal end positioned in the proximal interior volume portion and a distal end positioned in a lumen of the needle.

Abstract
A catheter insertion device includes a housing, a needle, a catheter, and a guide wire. The needle has a proximal end positioned in the housing and a distal end extending beyond a distal end of the housing in a first position. The catheter is positioned coaxially over the needle, and may include a flexible tube and a catheter hub on a proximal end of the flexible tube. A proximal portion of the flexible tube and the catheter hub may be positioned in the housing. The guidewire may have a proximal end positioned in the housing and a distal end positioned in a lumen of the needle. The catheter insertion device also may include a handle coupled to the catheter, wherein movement of the handle relative to the housing moves the catheter hub from a position in the housing to a position outside of the housing.
