Abstract
A safety insert for an extra-corporeal circuit includes a first half-shell and a second half-shell forming a shell defining an inner duct, at least part of the second half-shell being made with a translucent material; a first connector to be connected to the extra-corporeal circuit, and a second connector to be connected to a transducer; and a first hydrophobic semi-permeable membrane having a first area A1 and a second hydrophobic semi-permeable membrane having a second area A2, with the two membranes being arranged in series along the inner duct. In a front view, the extent of an overlapping area A12 of the membranes is between 0% and 50% of the smaller of the two areas A1, A2. An extra-corporeal circuit includes the safety insert.
Claims13
A safety insert or transducer protector for an extra-corporeal circuit, comprising:
- a first half-shell and a second half-shell forming a shell defining an inner duct, at least part of the second half-shell having a material of construction that is translucent or transparent;
- a first tubular connector adapted to be connected to a branch pipe from the extra-corporeal circuit, and a second tubular connector defined by the first half-shell and adapted to be connected to a transducer;
- and
- a first hydrophobic semi-permeable membrane having a first membrane area (A1) and a second hydrophobic semi-permeable membrane having a second membrane area (A2), said first and second membranes (i) being arranged in series along said inner duct and (ii) lying in substantially a same plane,
- with an overlapping area (A12) of said first and second membranes being between 0% and 50% of a lesser of the first and second membrane areas (A1, A2).
