Abstract

An injection system for injecting an injectate fluid into a blood vessel of the patient and for carrying out a blood pressure measurement of a patient. The injection system includes a catheter tube having a first end for penetrating the blood vessel of the patient, and a pressure sensor which is arranged close to a second end of the catheter tube and can sense a pressure of a liquid in the catheter tube as an indication of the blood pressure of the patient.

Description

[0001] This claims priority to German application DE 10 2005 060 079.4, filed Dec. 15, 2005, the entire disclosure of which is incorporated by reference herein.

[0002] The present invention relates to blood vessel catheter located proximate to a patient's body for measuring blood pressure, drawing blood samples or injecting fluids into a blood vessel of the patient. The present invention further relates to a system for drawing blood samples or injecting fluids into the blood vessel of the patient and for carrying out a blood pressure measurement of a patient. BACKGROUND

[0003] Measurement systems for measuring blood pressure of a patient's body are well known in clinical appliances. They usually comprise a rinsing fluid reservoir which is connected using a fluid flow tube to a catheter tube, which in use penetrates a patient's body such that the rinsing fluid is supplied as a continuous rinsing fluid stream. Along the rinsing channel one or more valves can be arranged to manually st...
