Motivation (1/2) Global market of blood pump is growing. Accordingly many blood pump is developed

Motivation (2/2) However, blood pump is the most important device to patient. Therefore, we should meet the scientific and reasonable standards So we develop the experimental test device for checking compatibility of future blood pumps

Goal Setting (1/2) Set main standards by referring to “Guideline for Evaluation” from ‘FDA koread’ and set other standards for compatibility To Get reliability of our device, we test existing pumps and compare results between data and proposed performance by company

Goal Setting (2/2) We should consider many factors but especially we focus on pump’s performance Therefore we choose 3 factors, RPM, Flow rate, Pressure FLOW PRESSURE RPM

FR/DP/Constraints Pressure ~ 1000 [mmHg] → 2000 [mmHg] Flow rate ~ 10 [L/min] → 15 [L/min] Cost, Size, Accuracy etc.

Schematic Design

Details (1/?) 1)Detail Properties about each part - Flowmeter - pressure sensor - Pipe - Motor - Pump connector - Daq system

Details (2/?)

Experimental Methods

Results 1. 기존 펌프의 성능 그래프로 제시 2.CFD 로 확인 ? Time(sec ) Flow rate (L/min ) Existing Pump Performance is Violet line Measured is Green line Error is in 1% so we get reliability Time(sec) Pres sure (kPa )

Conclusion 1.Measured performance is equal to proposed specification by company 2.So we get reliability that this tester could be used for checking compatibility of future blood pump

Future Works Etc
