2.4 FLUIDICS PARTS DESCRIPTION
The hydraulic part of the MYTHIC 18 is very simple and made of only three modules :
- Sampling module.
- Counting bath module.
- Syringes module.
The modules are connected together by semi rigid tubing.
2.4.1 Sampling module
This module (patent pending) enables to draw the sample and to perform the WBC and RBC/PLT dilutions.
It is assembled with a rotating rocker moving around a support which maintains the system to move up and
down the sampling needle.
A very reliable system of rack-gear moves the rocker.
The cleaning system of the sampling needle can be removed without tool (see section 9.3.2 in the user
manual).
The o-ring of the needle included in the cleaning system can also be removed without tool (see section 9.3.2
in the user manual).
The maintenance of these parts is very easy to perform.
2.4.2 Counting bath module
This module allows to count the WBC and RBC/PLA and to measure the HGB.
It is made with a manifold maintaining the reagent commutation valves and the counting bath block with their
measurement block including the apertures.
The counting bath block assembly and these apertures can be removed without tool (see section 9.3.3/4/5
in the user manual).
2.4.3 Syringes module
This module (patent pending) enables :
to draw the sample
to distribute the reagents
to drain the baths
to do the vacuum necessary for counting
and to push the waste to the waste container.
It is made with a manifold maintaining the fluid commutation valves and with the syringes bloc including five
syringes :
The sampling syringe
The lysis syringe
The two waste and vacuum/pressure syringes
And the diluent syringe.
Only one motor drives the five syringes.
The diluent input and the waste output are also included in this manifold.
