Summary
The Erythrometer measures red blood cell filterability and plasma viscosity. This device aids in assessing blood flow properties by analyzing red blood cell passage through membranes.
Area of Science:
- Biomedical Engineering
- Hematology
- Medical Devices
Background:
- Assessing red blood cell deformability is crucial for understanding blood flow.
- Existing methods for measuring red blood cell filterability can be complex.
- Plasma viscosity is another key hemorheological parameter.
Purpose of the Study:
- To introduce and describe the Erythrometer, a novel device.
- To evaluate the performance of the Erythrometer for measuring red blood cell filterability and plasma viscosity.
- To present initial results obtained using the Erythrometer.
Main Methods:
- The Erythrometer utilizes a steady flow rate to filter washed red blood cells through 3 or 5-micron membranes.
- Pressure drop across the membrane is monitored during filtration.
- A red blood cell filterability index is calculated based on pressure changes.
Main Results:
- The Erythrometer successfully determines red blood cell filterability.
- The device also measures plasma viscosity.
- Initial performance data and results were obtained and are presented.
Conclusions:
- The Erythrometer is a functional device for assessing key hemorheological properties.
- This instrument offers a new approach to measuring red blood cell filterability and plasma viscosity.
- Further results and applications of the Erythrometer are anticipated.
