The invention relates to a device for measuring at least one parameter of an arterial blood sample, including a flow sensor having standardized connecting elements which are connected to the inlet and the outlet side of a measuring cell of the flow sensor, the measuring cell having at least one optochemical sensor element which can be brought in contact with the blood sample. A connector is removably placed on the flow sensor and includes at least one light source for exciting the optochemical sensor element and at least one photodetector for receiving the measurement radiation of the optochemical sensor element. An electronic module has an electric connecting line to the connector and contacts the at least one light source and the at least one photodetector, the flow sensor being connectible to the standardized connection of an arterial catheter via the connecting element on the inlet side and to the standardized connection of an arterial infusion set via the connection on the outlet side.

Device for measuring at least one parameter of an arterial blood sample

Measuring devices are disclosed for determination of at least one parameter of a blood sample. The measuring device includes a flow-through measuring cell, in which is disposed luminescence-optical sensor elements, which can be brought into contact with the blood sample, and at least one light source for excitation of the luminescence-optical sensor element and at least one photodetector for receiving the luminescence radiation emitted by the luminescence-optical sensor element. The light source and the photodetector are located on opposite sides of the flow-through measuring cell. The sensor elements are placed on an excitation side of the flow-through measuring cell, which faces the light source, and the light source emits excitation radiation of wavelength less than 600 nm, while the luminescence radiation of the sensor elements lies in a wavelength range greater than 600 nm, thus exposing the excitation radiation to stronger absorption by the blood sample than the luminescence radiation.

Measuring device for determination of at least one parameter of a blood sample

A device for monitoring a parameter of a fluidic sample by microdialysis, the device comprising a permeable membrane, wherein the permeable membrane has a first surface to be brought in contact with the fluidic sample to traverse the permeable membrane (), wherein the permeable membrane has a second surface to be brought in contact with a dialysis fluid, and wherein the first surface is smoother than the second surface.
