Apparatus, method, system for the determination of the aggregation rate of red blood cells
The present invention generally relates to an apparatus, method, system for the determination of the aggregation rate of red blood cells. More specifically, the invention concerns a method, system, and the relative apparatus used to determine the aggregation rate of red blood cells, and other parameters related to these, such as viscosity, deformability, elasticity, density, in the field of in vitro medical analyses, using optical systems after or during inducted forces for red blood cell disruption and redistribution generated by ultrasound waves.
1. An apparatus comprising:
(a) a mixer device configured for mixing a blood sample within a collection tube;
(b) a needle configured for insertion within the collection tube for withdrawal of a portion of the blood sample, the needle connected to a hydraulic circuit for transporting the blood sample portion using a pump;
(c) a reading cell container operationally connected to the hydraulic circuit configured for receipt of the blood sample portion;
(d) a light emitter source positioned about the reading cell to pass light through the blood sample portion;
(e) an optical receiver positioned opposite the light emitter source and about the reading cell to detect scattered light passing through the blood sample portion; and
(f) a disruption mechanism connected to the reading cell container for disruption of the red blood cells within the blood sample portion to assist in recording the disruption rate.
2. The apparatus of claim 1 further comprising (g) a main controller operationally connected to the disruption mechanism, the main controller configured to activate the disruption mechanism for the disruption of the red blood cells within the blood sample portion until scattered light detected stops decreasing indicating the complete disruption of aggregates within the blood sample portion.
3. The apparatus of claim 2 further comprising (h) a fluid reservoir connected to the reading cell container for receipt of an evacuated blood sample portion from the reading cell container.
4. The apparatus of claim 3 further comprising (i) an evacuation mechanism to evacuate the blood sample portion from the reading cell container.
5. The apparatus of claim 4 wherein the evacuation mechanism is configured to provide ultrasound stress.
6. The apparatus of claim 1 , wherein the reading cell container is non-disposable.
7. The apparatus of claim 2 wherein the reading cell container is configured for the optical detection of aggregation reaction.
8. The apparatus of claim 2 wherein the disruption mechanism is an actuator.
9. The apparatus of claim 2 wherein the disruption mechanism is an ultrasonic inducted mechanism for the disruption of red blood cells aggregates.
10. The apparatus of claim 2 wherein the disruption mechanism is electricity from a piezoceramic material which is initially ramped up to a level where cell emulsification is detected through the reading cell.
