Abstract

The invention is directed to a blood pressure monitoring device comprising a central parts mounting module and to a method of manufacturing this parts mounting module. According to the invention fluid channels are produced by gas injection into the interior of the parts mounting module, the walls bounding the fluid channels being completely formed by the material of the parts mounting module. The injection of gas continues for as long as a core of the parts mounting module is still in the liquid phase in the area of the fluid channel, whilst an outer area surrounding the core has already solidified, so that the pressure fluid expels the liquid core area, producing a tubular fluid channel.
