An assembly useful in conjunction with a signal transmission means for the measurement of a compositional parameter of the blood of a patient is disclosed. This assembly comprises a housing adapted and sized to be located outside the body of a patient and having a fluid flow passage therethrough into which blood from the patient is passed from a hollow tube, the fluid flow passage being defined by a wall which is substantially impermeable to blood, the housing being adapted to be removeably secured to a signal transmission system such that the housing is capable of being removed from the signal transmission system without disrupting the fluid flow passage; and a sensing element located in the housing in or near the fluid flow passage for providing a signal directly to the signal transmission system in response to a compositional parameter of blood located in the fluid flow passage.

A sensor cassette for use in measuring a compositional parameter of the blood of a patient comprising: a housing adapted and sized to be located outside the body of the patient and having a fluid flow passage therethrough which is capable of receiving blood from the patient; and a sensing element located in said housing in or near said fluid flow passage for providing a signal in response to a compositional parameter of blood, said fluid flow passage at or near the location of said sensing element being at least 4.8 times as wide as its depth, the depth of said fluid flow passage extending directly outwardly from said sensing element and the wide direction of said fluid flow passage being substantially perpendicular to both the general direction of fluid flow in said fluid flow passage and to the depth of the fluid flow passage.
