STEINER OPU Technology for affordable OPU in Human INF

Components of autoclavable OPU System:
- Outer pipe: Needle guide
- Middle pipe with male Luer for SL Needle.
- Narrow pipe: for aspiration
The aim of this innovative technique was to replace 16 or 17gaugee DL-Needles with Sl Needles because they are expensive and have insufficient aspiration- and flushing effect.
