1. A sensing device for a one-time use medical device comprising:
a support component having a support surface for mounting thereon one or more electrically connected switches configured to actuate at a first pre-configured pressure and at a second pre-configured pressure, the one or more electrically connected switches comprising a first pressure switch, wherein the one or more electrically connected switches forms a sensor array adapted to sense expansion or contraction of the expandable tubing,
a length of expandable tubing for passing a fluid therethrough secured to the support surface by a securing means, and
a pressure concentrator positioned between the first pressure switch and a portion of the length of expandable tubing, the pressure concentrator having an upper surface in physical contact with the portion of the length of expandable tubing, and a lower surface in physical contact with the first pressure switch, the pressure concentrator being shaped to concentrate pressure from expansion or contraction of the expandable tubing to the first pressure switch, wherein the concentrator is configured to modulate the pressure actuation threshold of the first pressure switch to the first pre-configured pressure.
