Patent ID: 8092414

Claim:
A tubular blood flow set which comprises a pressure sensing pod defining a chamber, said pod being connected in flow-through relation to blood flow tubing of said set, said set defining a length of pressure tubing connected at one end with said chamber, for connection at the other pressure tubing end with a pressure measuring equipment connector with said pod being spaced from said connector; and a flexible diaphragm sealingly mounted within said pod between connections of said blood flow tubing and said pressure tubing, said diaphragm being moveable between first and second positions, the diaphragm in said first position bowing outwardly to substantially maximize volume in said chamber that communicates with said blood flow tubing, the diaphragm in said second position bowing inwardly to substantially minimize but not eliminate the blood volume in said chamber that is inside of said diaphragm, said diaphragm in use being in contact on one side thereof with flowing blood; wherein the pressure tubing is flexible and elongate and integrally attached to the chamber to permit the pod to be positioned remotely from the pressure measuring equipment connector and to permit the pod and blood flow tubing set to be connected to blood treatment machines with pressure measuring equipment connectors in various locations of the blood treatment machines.
