Abstract

A hydraulic system for a flow cytometry having a reservoir for a sheath solution, at least one syringe connected to the reservoir, the at least one syringe being driven by a motor, a single HGB module connected on an inlet side to a sample inlet which is connected to the flow cell by a single flow path passing through the HGB module, a single flow cell connected to the HGB module and at least one syringe on an inlet side of the flow cell, and to a waste container on an outlet side of said flow cell.

Claims (10)

1. A hydraulic system for a flow cytometer, comprising:

a reservoir for a sheath solution;

at least one syringe connected to said reservoir, said at least one syringe being driven by a motor such that said at least one syringe draws said sheath solution from said reservoir;

a single HGB module, said HGB module being connected on an inlet side to a sample inlet;

said sample inlet being connected to a flow cell by a single flow path passing through said HGB module; and

said flow cell being connected to said HGB module and said at least one syringe on an inlet side of said flow cell, and to a waste container on an outlet side of said flow cell.

2. A hydraulic system according to claim 1 , wherein said sample inlet includes a needle effective to pierce a stopper on a blood collection tube and aspirate a sample in said tube.

3. A hydraulic system according to claim 1 , comprising at least two syringes connected to said reservoir, each of said at least two syringes being driven by a motor.

4. A hydraulic system according to claim 1 , further comprising a plurally of valves to control flow through said hydraulic system.

5. A hydraulic system according to claim 4 , wherein the number of said valves is not greater than five.
