Assignee: DATAMED S.R.L.
Field: Measurement (Instruments)
Classification: CPC A  G | IPC A  G

Claim 0:
1. A device for measuring a blood parameter, preferably related to the presence or concentration of oxygen in blood, comprising:
a box body,
a coupling portion associated to the box body and comprising at least one coupling element, the coupling portion being configured to feature:
a coupled configuration wherein it is coupled to a container by said at least one coupling element,
a decoupled configuration wherein it is not coupled to a container,

a container, for example a tubular element, apt to contain blood and/or in which blood can flow, the container being configured to be coupled to said coupling portion,
a photosensitive element associated to the container and apt to respond, at the end of an excitation to which it is subjected when it is in contact with blood, with a light response, the light response providing a luminescence decay curve, in operative conditions the photosensitive element being in contact with blood,
an excitation member housed inside the box body and configured to excite said photosensitive element by a series of excitation pulses,
a photodetector housed inside the box body and configured to detect, in operative conditions of the device, a plurality of light responses of the photosensitive element corresponding to the series of excitation pulses, the light responses providing luminescence decay curves, and
a control unit housed inside the box body and configured to perform the following operations:
receiving, for each of at least two time windows in which each luminescence curve is analyzed, one or more light response analog information regarding the luminescence decay curve,
converting the light response analog information, detected at least two time windows for each light response, into light response digital data,
processing said light response digital data and the actual temperature value of blood by considering a plurality of data of previous measures of said blood parameter performed during previous training,
determining, as a result of the processing operation, at least one value of said blood parameter.
