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

摘要

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.

主权项

1. A device for measuring at least one parameter of an arterial blood sample, the device comprising:
a disposable flow-through sensor including a measuring cell configured to receive the arterial blood sample; wherein the measuring cell is detachably connected between an inlet standardized connecting element and an outlet standardized connecting element of the flow-through sensor; at least one optochemical sensor element within the measuring cell that contacts the arterial blood sample received by the measuring cell; a reusable connector, which can be detachably plugged externally onto the flow-through sensor including the measuring cell containing the at least one optochemical sensor element, the connector including at least one light source for excitation of the optochemical sensor element and at least one photodetector for receiving the measurement radiation of the optochemical sensor element, wherein the at least one light source and the at least one photodetector of the connector do not come in contact with the received arterial blood sample when the connector is plugged onto the flow-through sensor, an electronic module with an electrical connecting line to the connector, the module in contact with the at least one light source and the at least one photodetector, the inlet standardized connecting element coupled to an inlet side of the measuring cell for removable connection to a standardized fitting of an arterial catheter; and the outlet standardized connecting element coupled to an outlet side of the measuring cell for removable connection to a standardized fitting of an arterial infusion set.
