The Engineer Online reports on Probe Scientific, a firm out of Bedford, UK, that has developed a continuous blood composition monitoring device that doesn’t draw blood from the patient. The MicroEye system connects via most venous catheters and is already approved in Europe.
From the product page:
The MicroEye is intended for intravenous use for periods of up to 48 hours and is inserted via an 18G blood catheter. The range of substances that can be monitored using the MicroEye is vast including:
Electrolytes (such as potassium, magnesium etc.) Energy metabolites (e.g. glucose, lactate, pyruvate, etc.) Amino acids (glutamate, GABA, etc.) Hormones and neurotransmitters (such as dopamine, serotonin (5-HT) etc.) Inflammatory mediators and growth factors (e.g. cytokines, etc.) Drugs and their metabolites (unbound ‘free’ fraction and / or total)
