Problems solved by technology

[0007] A typical sampling unit for current TBM systems is a hard plastic cup approximately 2 cm in diameter, which limits the parts of the neonate's body to which the system can be attached
The system must be attached to a flat surface of the skin to avoid leaks, which typically limits attachment to the patient's torso where it must compete for space with other equipment such as ECG electrodes

Abstract

The present invention relates to a sampling unit, a measurement system and method for transcutaneous blood gas measurements. In particular the invention relates to a sampling unit and system adapted for rapid measuring and monitoring of blood gases in a continuous gas flow. The sampling unit is provided with an ambient air inlet and a blood gas extraction and mixing chamber wherein air is mixed with extracted blood gases. The method of continuous transcutaneous measurement of carbon dioxide in the blood utilizes a pulsed heating to minimize the detrimental effects of the heating.

Description

technical field [0001] The invention relates to a sampling unit, a measurement system and a method for percutaneous blood gas measurement. In particular, the present invention relates to sampling units and systems suitable for rapid measurement and monitoring of blood gases in a continuous gas flow, and a method for continuous transcutaneous measurement of carbon dioxide in a patient's blood, wherein the patient's skin is heated to minimize adverse effects of heating . Background technique [0002] Transcutaneous blood gas measurements (TBM) are critical in monitoring the health of premature infants. Blood gas refers to the oxygen (O 2 ) and carbon dioxide (CO 2 ), while transcutaneous refers to measurements made through the skin. Approximately 75 percent of all newborns are monitored by TBM during hospitalization, making it one of the most widely used methods in the modern Neonatal Intensive Care Unit (NICU) [1]. [0003] Together with measurements of pulse, respirator...
