Abstract

The invention relates to a system for analyzing a liquid sample, including an analysis device comprising a casing including a through-opening leading into a housing adapted to receive a portion of a collecting device and extending longitudinally from the opening along an axis of insertion of the collecting device. The analysis system further includes a collecting device comprising a main body extending along a longitudinal axis and including a fluid chamber adapted to be inserted in the housing along the insertion axis and a receiving surface intended to receive the liquid sample extending substantially orthogonally relative to the axis of the main body.

Claims

1-18. -18. (canceled)

19. A system for analyzing a liquid sample, including an analysis device comprising:

a casing delimiting an interior space and comprising a through-opening leading to a housing adapted to receive a portion of a device for collecting said liquid sample and disposed in the interior space to extend longitudinally from the opening along a so-called insertion longitudinal axis of the collecting device,

a device for detecting and analyzing at least one representative parameter of the liquid sample,

and including a device for collecting said liquid sample comprising;

a main body extending along a longitudinal axis and including a measurement fluid chamber adapted to be inserted longitudinally into the housing along the insertion longitudinal axis of the latter;

a receiving surface intended to be situated outside the housing to receive the liquid sample when the main body is inserted into the housing, assembled to the main body and extending substantially orthogonally to the longitudinal axis of the main body, and comprising a collecting orifice in fluid communication with the measuring chamber.

20. The system according to claim 19, wherein the housing of the analysis device and the collecting device are both sized so that, when the main body of the collecting device is inserted in the housing, the distance between the collecting orifice and the measuring chamber is approximately equal to the distance between the opening of the housing and the measuring chamber, and is preferably less than or equal to 2 cm.

21. The system according to claim 19, wherein the collecting device includes a collecting portion assembled to the main body and one surface of which forms the receiving surface, this collecting portion being in contact with a wall of the casing at the edge of the opening of the housing when the main body of the collecting device is inserted in the housing.

22. The system according to claim 19, wherein the casing includes an upper wall and a lower wall connected to each other by a lateral wall having dimensions less than the dimensions of the upper and lower walls, the opening of the housing is situated at the level of the upper wall of the casing and the housing extends substantially orthogonally to the latter in the direction of the lower wall.

23. The system according to claim 22, wherein the upper wall of the casing comprises a display screen.

24. The system according to claim 19, including a bearing surface fixed relative to the housing and disposed so as to delimit in part the housing by extending parallel to the longitudinal axis of the housing and so as to be in contact with a portion of the main body containing the measuring chamber of the collecting device when the latter is inserted in the housing.

25. The system according to claim 24, wherein the detection and analysis device includes an optical sensor situated on a side of the bearing surface opposite the housing, the bearing surface being transparent to light beams coming from the measuring chamber when the main body of the collecting device is inserted in the housing.

26. The system according to claim 19, wherein the detection and analysis device includes an optical sensor situated at a longitudinal distance relative to the opening of the housing less than or equal to 2 cm.

27. The system according to claim 19, including a locking and disengagement device adapted to retain the main body in a locking position inside the housing and comprising:

a disengagement member adapted to exert an exit force on the main body when the latter is inserted in the housing in a direction parallel to the longitudinal axis of the housing and oriented toward the opening of the housing;

a locking member including at least one abutment portion adapted to be in contact with a bearing portion of the main body when the latter is inserted in the housing in the locking position so as to immobilize the collecting device subjected at this time to the exit force along the longitudinal axis of the housing.

28. The system according to claim 27, wherein the bearing portion of the main body of the collecting device is formed by a lateral shoulder of the main body situated between a so-called central first portion containing the measuring chamber and a distal end of the main body relative to the receiving surface.

29. The system according to claim 24 the bearing surface and projecting relative to the latter in the direction of the housing, the longitudinal ends of which are bevelled so as to space the main body relative to the bearing surface upon movement of the latter in the housing along the longitudinal axis.

30. The system according to claim 27, wherein the locking member is mobile relative to the housing substantially transversely to the longitudinal axis of the latter and adapted to exert a bearing force on the main body in the direction of the bearing surface when the latter is inserted in the housing.

31. The system according to claim 27, wherein the locking and disengagement device includes an unlocking member actuation of which is adapted to cause movement of the locking member so as to cause the breaking of the abutment between the abutment portion of the latter and the bearing portion of the collecting device leading to withdrawal of the main body relative to the housing by the effect of the exit force.

32. The system according to claim 27, wherein the detection and analysis device includes at least one light source and an optical sensor disposed on respective opposite sides of the housing along an axis of illumination of the measuring chamber when the main body of the collecting device is inserted in the housing, the locking member including a hollow portion positioned between the light source and the optical sensor enabling propagation of the illumination beams along the illumination axis through said hollow portion.

33. The system according to claim 19, further comprising a heating device comprising a heating element adapted to transmit heat to the measuring chamber via the bearing surface when the main body is inserted in the housing and in contact with the bearing surface.

37. The system according to claim 19, wherein the detection and analysis device includes an optical sensor situated at a transverse distance relative to the housing less than or equal to 2 cm.
