    摘要: A system for measuring and indicating pressure that uses as its pressure sensing element an outer resilient tube, an inner resilient tube, and a rolling diaphragm connecting the inner and outer tubes, and held inside a protective enshrouding structure where pressure applied to the annulus between the tubes causes the diaphragm to deform and roll to axial extend the outer tube by an amount proportional to the applied pressure. The structure has features that enable visual correlation of the partially rolled tube's unrolled state with the applied pressure. The system can be incorporated into a syringe to create a pressure measuring syringe for inflating endotracheal cuffs while providing a reading of the cuff pressure.
