WE CLAIM:
1. A hematology analyzer (100) for analyzing a fluid sample, comprising:
a frame body (102) having
a platform (104);
a pair of rails (114) arranged above the platform (104) and supported by
one or more columns (116); and
the frame body (102) defines a first axis (X-X’) along the pair of rails
(114) and a second axis (Y-Y’) that is perpendicular to the first axis (X-X’) and
the platform (104);
a cartridge unit (200) comprising at least two compartments (202, 204, 206,
208), in which a first compartment (202, 206) of the at least two compartments contains
the fluid sample to the analyzed and a second compartment (204, 208) of the at least
two compartments contains a cleaning fluid;
a first transmission unit (120) provided on the pair of rails (114) and configured
to:
hold the cartridge unit (200); and
move the cartridge unit (200) along the first axis (X-X’) of the frame
body (102);
a second transmission unit (150) provided on the platform (104); and
a fluid analysis module (170) disposed on the second transmission unit (150)
and adapted to move along the second axis (Y-Y’) of the frame body (102) by the
second transmission unit (150), the fluid analysis module (170) comprising a first probe
(172) and a second probe (182),
wherein,
the first transmission unit (120) is configured to move the cartridge unit (200)
along the first axis (X-X’) of the frame body (102) to align the first compartment (202,
206) and the second compartment (204, 208) with the first probe (172) and the second
probe (182), respectively, and
the second transmission unit (150) is configured to move the fluid analysis
module (170) along the second axis (Y-Y’) of the frame body (102) such that the first
probe (172) pierces the first compartment (202, 206) and the second probe (182) pierces
the second compartment (204, 208)

2. The hematology analyzer (100) as claimed in claim 1, wherein the cartridge unit (200)
comprises four compartments, in which
the first compartment (202) contains a red blood cells sample to be analyzed;
the second compartment (204) contains the cleaning fluid;
a third compartment (206) contains a white blood cells sample to be analyzed;
and
a fourth compartment (208) contains the cleaning fluid.
3. The hematology analyzer (100) as claimed in claim 1, wherein each compartment of
the at least two compartments (202, 204, 206, 208) comprises an elastomeric seal (210)
which is adapted to be pierced by the respective probe (172, 182) of the fluid analysis
module (170).
4. The hematology analyzer (100) as claimed in claim 2, wherein each of the red blood
cells sample and the white blood cells sample is prepared by mixing the fluid sample
with one or more reagents,
the one or more reagents mixed with the fluid sample to form the red blood cells
sample comprises hematology diluent, and
the one or more reagents mixed with the fluid sample to form the white blood
cells sample comprises LYSE.
5. The hematology analyzer (100) as claimed in claim 1, wherein the cleaning fluid cleans
the first probe (172) of the fluid analysis module (170) and comprises RINSE.
6. The hematology analyzer (100) as claimed in claim 2, wherein
the red blood cells sample and the white blood cells sample are prepared in the
cartridge unit (200) outside the hematology analyzer (100), and
the cartridge unit (200) is a disposable cartridge unit (200).
7. The hematology analyzer (100) as claimed in claim 1, wherein the fluid analysis module
(170) is configured to count red blood cells (RBCs), white blood cells (WBCs),
hemoglobin, and platelet counts.

8. The hematology analyzer (100) as claimed in claim 2, wherein the second probe (182)
comprises a three-way valve adapted to supply the cleaning fluid to the first probe (172)
to clean the first probe (172) internally and externally.
9. The hematology analyzer (100) as claimed in claim 1, wherein the first transmission
unit (120) comprises:
a first actuator (122);
a drive shaft (126) and a driven shaft (128) adapted to be driven by the first
actuator (122);
a first roller (132) and a second roller (134) disposed opposite to the drive shaft
(126) and the driven shaft (128), respectively; and
a first conveyer belt (138) extending between the drive shaft (126) and the first
roller (132) and a second conveyer belt (140) extending between the driven shaft (128)
and the second roller (134),
each of the first conveyer belt (138) and the second conveyer belt (140) is
adapted to be driven by the first actuator (122) such that the cartridge unit (200) held
by the first transmission unit (120) is movable along with the first axis (X-X’) of the
frame body (102).
10. The hematology analyzer (100) as claimed in claim 9, wherein each of the first conveyer
belt (138) and the second conveyer belt (140) comprises a plurality of segments (144)
for holding the cartridge unit (200)
