CATHETER SYSTEMS WITH BLOOD MEASUREMENT DEVICE AND METHODS
First Claim
1. A catheter system for use in positioning a distal end of a catheter body at a desired location in a patient'"'"'s body, comprising:
- a needle provided at the distal end of the catheter body to withdraw blood from the patient'"'"'s body, the needle fluidically connected to a proximal end of the catheter body;
a measurement device provided at the proximal end of the catheter body, the measurement device configured to receive blood withdrawn by the needle for measuring a blood gas value of the blood for use in positioning the distal end of the catheter body at the desired location in the patient'"'"'s body.

Abstract
Catheter systems with blood measurement device and methods are disclosed. An exemplary catheter system for use in positioning a distal end of a catheter body at a desired location in a patient'"'"'s body may include a needle provided at the distal end of the catheter body to withdraw blood from the patient'"'"'s body. The needle is fluidically connected to a proximal end of the catheter body. The catheter system may also include a measurement device provided at the proximal end of the catheter body. The measurement device is configured to receive blood withdrawn by the needle for measuring a blood gas value of the blood for use in positioning the distal end of the catheter body at the desired location in the patient'"'"'s body.

12. A catheter system comprising:
-
a catheter body having a proximal end and a distal end, the proximal end having a handle for positioning the distal end in a patient'"'"'s body, a needle insertable through the catheter body to the distal end of the catheter body, the needle configured to withdraw blood from the patient'"'"'s body near the distal end of the catheter body; a measurement device provided at the proximal end of the catheter body, the measurement device measuring a blood gas value of the blood; and an output device operatively associated with the measurement device, the output device configured to output information based on the blood gas value for use in positioning the distal end of the catheter body at the desired location in the patient'"'"'s body. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method for use in positioning a catheter at a desired location in a patient'"'"'s body, comprising:
-
inserting the catheter into the patient'"'"'s body; withdrawing blood from the patient'"'"'s body at a distal end of the catheter, and transferring the withdrawn blood through the catheter to a proximal end of the catheter; measuring at least one parameter in the withdrawn blood at the proximal end of the catheter while the catheter remains inserted in the patient'"'"'s body; and using the at least one measured parameter to assist in positioning the catheter at the desired location in the patient'"'"'s body. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
